North Carolina Form D-400 Schedule PN is the Part-Year Resident and Nonresident Schedule that part-year residents and nonresidents must attach to Form D-400 to figure the share of total income that North Carolina can tax. The schedule turns your federal income into a North Carolina taxable percentage on Line 24, and that one decimal drives the tax on Line 14 of your D-400.
If you moved into or out of North Carolina during 2025, or you lived elsewhere but earned NC-source income, the Department of Revenue will not accept your return without this schedule. According to the NCDOR Individual Income Tax filing requirements page, thousands of part-year and nonresident returns are flagged each season for missing or miscomputed Schedule PN attachments, and the most common rejection reason is a mismatch between Column A (federal) and Column B (NC) totals.
Here is what you will learn in this guide:
- 📄 What Schedule PN does and exactly who must file it
- 🧾 Every document, date, and ID number to gather before you start
- ✏️ A line-by-line walkthrough of Parts A, B, and C, including the Line 24 decimal
- 👥 Three real scenarios — a mover-in, a mover-out, and a full-year nonresident
- ⚠️ The mistakes that trigger NCDOR notices, and how to avoid them
What the Form Is and Who Must File It
Schedule PN is the worksheet that allocates income between the world (Column A) and North Carolina (Column B). The form was last revised 9-25, meaning the 2025 D-400 Schedule PN Web-Fill version is the one you want for returns covering tax year 2025 filed in 2026. Using an older revision is a frequent reason returns are kicked back for rework.
You must file Schedule PN if any one of these is true. You moved into North Carolina during 2025 and became a resident. You moved out of North Carolina during 2025 and became a resident of another state. You were never an NC resident in 2025 but received NC-source income, such as wages from an NC employer, rental income from NC property, gambling winnings from an NC casino, or pass-through income from an NC business.
The legal authority is N.C. Gen. Stat. § 105-153.4(b) and (c), which defines NC taxable income for part-year residents and nonresidents as federal taxable income multiplied by the ratio of NC-source income to total income from all sources. The receiving agency is the North Carolina Department of Revenue. The deadline tracks the federal deadline, so 2025 returns are due April 15, 2026. The penalty for late filing is 5% per month up to 25%, plus a 10% late-payment penalty and interest at the rate published quarterly by NCDOR.
If you and your spouse were both full-year NC residents, you do not file Schedule PN. If only one spouse was a full-year resident and you file jointly, you still file Schedule PN because the nonresident spouse’s status pulls the return into part-year/nonresident territory.
Before You Start: Documents and Information You Need
Gather these items before you open the form. Missing any one of them is the single biggest cause of stop-and-restart, and the 2025 D-401 Individual Income Tax Instructions lists most of them in its part-year section.
- Federal Form 1040 for tax year 2025, fully completed. Schedule PN starts from federal AGI line items, so a finished federal return must come first; without it, every Column A number is a guess.
- Every W-2 you received in 2025. Box 15 shows the state, and Box 16 shows state wages, which is how you split wages between NC and another state.
- Every 1099 (1099-NEC, 1099-MISC, 1099-INT, 1099-DIV, 1099-R, 1099-G, SSA-1099). The payer’s address and the income’s source decide whether it lands in Column B.
- Exact NC residency dates. Write down the date you became an NC resident and the date you stopped being one, because Part A asks for both. A guessed date can void the residency claim.
- Lease, deed, or driver’s license update showing the move date. NCDOR can request proof, and a license issue date is the cleanest evidence.
- Other-state tax return if you are claiming a credit for tax paid to another state on Form D-400TC. Without it, the credit is denied.
- K-1s from partnerships, S-corps, estates, or trusts. The K-1 sourcing footnotes drive Column B for pass-through income.
- Closing statements for any NC real estate sold in 2025. Capital gain on NC property is NC-source even if you live elsewhere.
- Records of NC gambling, lottery, or prize winnings. NC sources these to the state where the wager was placed.
- Your prior-year NC return, if any. It speeds up identity verification and confirms how you classified residency last year.
Where to Get the Form and How to Access It
The official 2025 schedule is hosted on the NCDOR forms page at the 2025 D-400 Schedule PN form page. Two versions are posted: a Web-Fill PDF you can type into in any browser, and a Handwritten version you print and complete in blue or black ink. Always download from ncdor.gov rather than third-party form mills, because revision dates and barcodes change yearly.
If your return needs Other Additions or Other Deductions on Schedule PN Part B Line 17e or Line 19h, you also need Schedule PN-1. Both pages of PN-1 must be attached even if only one part is used, or NCDOR may be unable to process the return.
Tax software supports Schedule PN automatically. The NCDOR eFile partner list shows which providers (TurboTax, H&R Block, TaxAct, FreeTaxUSA, TaxSlayer) carry the schedule. If you prefer paper, the form ships inside the D-401 instruction booklet. You can also request paper forms by calling NCDOR at 1-877-252-3052.
If you are visually impaired or need accommodation, NCDOR’s taxpayer assistance offices in Asheville, Charlotte, Durham, Elizabeth City, Fayetteville, Greensboro, Greenville, Hickory, Raleigh, Rocky Mount, Wilmington, and Winston-Salem provide in-person help. Bring photo ID and last year’s return.
Step-by-Step: How to Fill Out Form D-400 Schedule PN Line by Line
Schedule PN has three parts. Part A captures residency status. Part B allocates income between Column A (everywhere) and Column B (NC). Part C calculates the taxable percentage on Line 24 that you carry to Form D-400 Line 13. Each H3 below follows the form’s exact field names and box order printed on the 2025 Schedule PN Web-Fill version.
Taxpayer Name and Social Security Number Header
The header asks for your name and SSN exactly as they appear on Form D-400. Type the names in the same order: primary filer first, spouse second on a joint return.
Match the spelling and SSN to your Social Security card and to the federal 1040, because NCDOR runs a name/SSN match against IRS data. Maria Lopez writes MARIA LOPEZ and 123-45-6789 in the header boxes.
If you changed your name during the year through marriage or divorce, use the name now on file with the Social Security Administration. A common mistake is writing a married surname before the SSA record is updated, which causes a mismatch hold and a delay of 6 to 10 weeks.
The misconception here is that NCDOR will accept “close enough” name variants. It will not — the agency cross-checks names character by character against SSA records.
Part A, Line 1: Were you a resident of N.C. for the entire year?
This field asks, in plain English, whether you lived in North Carolina every single day of 2025. Fill in the Yes circle if you were a full-year NC resident, otherwise fill in No.
If you fill in No, you must then enter the dates you were an NC resident in 2025 on the lines provided. Marcus Reed moved to Charlotte from Atlanta on July 1, 2025, so he marks No and writes 07/01/2025 to 12/31/2025.
A common edge case is the snowbird who keeps a North Carolina home but spends most of the year in Florida. Domicile, not days, controls — if NC is your true permanent home, you are a full-year resident even if you slept here only a few months.
The mistake to avoid is marking Yes when you were actually a part-year resident. The consequence is that NCDOR will tax 100% of your worldwide income, ignoring your residency change.
A misconception filers carry is that “183 days” automatically makes you a resident. NC uses a domicile test plus a 183-day statutory residency rule for those who maintain a place of abode in NC, not a simple day count.
Part A, Line 2: Was your spouse a resident of N.C. for the entire year?
Skip this line if you are filing single or head of household. On a joint return, fill in Yes or No for the spouse and, if No, list the spouse’s NC residency dates.
If you and your spouse have different residency periods, both date ranges go on the form. Janet and David Park both moved from Virginia on March 15, 2025, so both ranges read 03/15/2025 to 12/31/2025.
The edge case: a military servicemember stationed in NC under orders is generally not an NC resident, while the civilian spouse may be — see the federal Servicemembers Civil Relief Act and the Military Spouses Residency Relief Act (MSRRA). Document each spouse separately.
A common mistake is using the same dates for both spouses out of habit. The consequence is an incorrect Column B allocation that overstates or understates NC tax.
The misconception: filing jointly does not merge residency. Each spouse keeps their own residency status, even on a joint return.
Part B, Line 3: Wages, Salaries, Tips, etc.
This line asks for total wage income. Column A gets the federal wage figure from Form 1040 Line 1z. Column B gets only the wages earned while you were an NC resident plus any wages from work physically performed in NC.
Read your W-2 Box 16 for the NC portion. Aisha Patel, a remote worker who lived in Raleigh from January through June and then moved to Texas, enters $80,000 in Column A and $40,000 in Column B (the six months of NC-resident wages).
The edge case is the cross-border commuter. If you lived in Virginia and drove to a job in Charlotte all year, none of your residency was in NC, but every paycheck is NC-source and goes in Column B.
A common mistake is using a 6/12 fraction instead of the actual W-2 Box 16 number, especially when bonuses or stock vesting hit unevenly. The consequence is an audit notice asking for W-2s and pay stubs.
The misconception is that telework from outside NC for an NC employer is not NC-source. Under NCDOR sourcing rules, wages are sourced to where the work is performed, not where the employer sits.
Part B, Line 4: Interest Income from Federal Form 1040
Enter total federal taxable interest in Column A, taken from Form 1040 Line 2b. Column B gets only the interest received while you were an NC resident.
For nonresidents, Column B is generally zero, because interest from intangible personal property is not NC-source unless the underlying loan is part of an NC trade or business. Carlos Mendez, a Florida resident with no NC business, enters $1,200 in Column A and $0 in Column B.
The edge case is interest paid into a brokerage account with an NC mailing address but earned while you lived elsewhere. The address does not change sourcing — residency on the date of receipt does.
The mistake is allocating brokerage interest by 12-month proration. The consequence is overstated NC income for movers-in who got most of their interest before the move.
A misconception: people think NC taxes municipal bond interest. NC exempts interest on its own bonds and on U.S. obligations, so adjust on Schedule S if needed.
Part B, Line 5: Ordinary Dividends
Column A is Form 1040 Line 3b. Column B captures only the dividends received during NC residency.
Dividends are sourced like interest: to the recipient’s residence on the payment date. Janet Park received a $2,400 dividend on June 30 while still in Virginia, and a $2,400 dividend on December 30 after moving to NC, so Column A is $4,800 and Column B is $2,400.
The edge case is qualified dividends inside a traditional brokerage. Qualification status does not change sourcing — only the residency on the payment date matters.
A common mistake is using the year-end 1099-DIV total without splitting by date. The consequence is a Schedule PN that does not tie to bank records if NCDOR asks for the breakdown.
The misconception is that REIT or mutual fund dividends are NC-source if the fund holds NC property. They are not — the fund’s portfolio composition does not pierce through to the shareholder.
Part B, Line 6: Taxable Refunds, Credits, or Offsets of State and Local Income Taxes
Column A pulls from Form 1040 Schedule 1 Line 1. Column B is generally zero for everyone, because NC does not tax state tax refunds.
If your federal return reports a taxable state refund, you will subtract it on Form D-400 Schedule S as an NC deduction. Marcus Reed enters his federal $300 refund in Column A and $0 in Column B.
The edge case is a refund from a state other than NC that was deducted on a prior NC itemized return. Special rules can apply, so check the D-401 instructions.
A common mistake is forgetting to also take the deduction on Schedule S. The consequence is paying NC tax on a refund that NC does not tax.
The misconception that filers hold is that if Column B is zero, they can leave the line blank. NCDOR prefers an explicit 0 to confirm the line was considered, not skipped.
Part B, Line 7: Alimony Received
Column A is Form 1040 Schedule 1 Line 2a. Column B includes only alimony received while you were an NC resident under a pre-2019 divorce decree.
Post-2018 divorces are not federally taxable, so they do not appear on the federal return or here. Aisha Patel received $6,000 of pre-2019 alimony, $3,000 of it while living in NC, so Column A is $6,000 and Column B is $3,000.
The edge case is recapture of front-loaded alimony, which is governed by federal rules and stays on the federal return; it does not change NC sourcing.
A common mistake is including child support, which is not taxable anywhere. The consequence is overpaying both federal and NC tax.
The misconception is that all post-divorce payments are alimony. Property settlements are not, and they belong nowhere on Schedule PN.
Part B, Line 8: Business Income or Loss
Column A pulls from Form 1040 Schedule 1 Line 3. Column B captures the share of net Schedule C income earned in NC or while an NC resident.
For a brick-and-mortar NC business owned by a nonresident, all of the income is NC-source. Carlos Mendez runs a consulting LLC; the $50,000 profit was earned entirely from Florida clients, so Column A is $50,000 and Column B is $0.
The edge case is a service business that performs work in multiple states. Apportion using a reasonable method tied to where services were rendered, and keep the workpaper.
The mistake is using gross receipts instead of net income. The consequence is a wildly inflated Column B and a tax bill that will not match Schedule C.
A misconception is that an LLC organized in NC automatically makes all income NC-source. The state of organization is not the test — the location of the business activity is.
Part B, Line 9: Capital Gain or Loss
Column A is Form 1040 Line 7. Column B includes gain on NC real property regardless of residency, plus gains on intangibles realized while you were an NC resident.
NC real estate sales by nonresidents are NC-source on day one. Janet Park sold a Charlotte rental for a $30,000 gain in February 2025 before moving to NC, and the entire gain is NC-source.
The edge case is a like-kind exchange under IRC §1031. Deferral works for federal purposes, and NC follows it, but the eventual taxable gain stays NC-source if it traces back to NC property.
A common mistake is netting gains and losses across states. The consequence is a misallocation that NCDOR rebuilds during exam.
The misconception is that unrealized gains matter. They do not — only realized, recognized gains hit Schedule PN.
Part B, Line 10: Other Gains or Losses
Column A comes from Form 1040 Schedule 1 Line 4. Column B includes only Section 1231 or ordinary gains tied to NC property or NC business activity.
Equipment sold from an NC trade or business is NC-source even for a nonresident owner. Marcus Reed sold a delivery van used in his Charlotte route, generating a $5,000 ordinary gain that lands fully in Column B.
The edge case is the sale of partnership interests when the partnership owns NC assets. Look-through rules can apply under N.C. Gen. Stat. § 105-153.4.
The mistake is forgetting depreciation recapture. The consequence is understated NC income and a recapture-driven adjustment letter.
A misconception is that personal-use property losses can offset NC income. They cannot — personal losses are nondeductible.
Part B, Line 11: IRA, Pension, and Annuity Distributions
Column A is the federal taxable amount from Form 1040 Lines 4b and 5b. Column B includes only distributions received while you were an NC resident.
Federal law in 4 U.S.C. § 114 bars states from taxing the retirement income of former residents. So a nonresident former NC resident reports $0 in Column B for any pension that started after they left.
The edge case is Bailey settlement income — vested NC government and federal retirees receive a full NC deduction under the Bailey decision, claimed on Schedule S, not Schedule PN.
A common mistake is taxing rollover amounts. The consequence is double tax that requires an amended return to fix.
The misconception is that 401(k) distributions follow the employer’s state. They do not — they follow the recipient’s state of residence on the date of distribution.
Part B, Line 12: Rental Real Estate, Royalties, Partnerships, S Corporations, Trusts
Column A is Form 1040 Schedule 1 Line 5. Column B is income tied to NC rental property, NC royalties, or the NC-apportioned share of pass-through K-1 income.
K-1 issuers send a state schedule showing NC apportionment. Aisha Patel’s K-1 from a Greensboro partnership shows $15,000 in Box 1 with $9,000 apportioned to NC, so Column A is $15,000 and Column B is $9,000.
The edge case is an S-corp that elected the NC Pass-Through Entity Tax (PTET). The owner backs out the PTET addition on Schedule S, but Column B still reflects the NC apportionment.
The mistake is using the federal K-1 number without the state apportionment schedule. The consequence is over-reporting NC income.
The misconception is that passive losses pass through unrestricted. NC honors the federal passive loss rules, so suspended losses stay suspended.
Part B, Line 13: Farm Income or Loss
Column A is Form 1040 Schedule 1 Line 6. Column B is the share earned from NC farm operations or while an NC resident.
Farm income is sourced to where the farm sits. Carlos Mendez’s tobacco farm in Wilson County produced $80,000 of income, fully NC-source, even though he lives in Florida.
The edge case is custom farming services performed across the state line. Apportion by acres serviced or revenue earned in each state.
A common mistake is netting farm and Schedule C activity. The consequence is an unmatchable return.
The misconception is that conservation reserve payments follow the recipient’s residence. They follow the land.
Part B, Line 14: Unemployment Compensation
Column A is Form 1040 Schedule 1 Line 7. Column B includes only unemployment received while you were an NC resident.
NC sources unemployment to the recipient’s residence on the payment date. Marcus Reed received $3,600 of NC unemployment after moving to NC, all of it Column B.
The edge case is benefits paid by another state’s agency to someone now living in NC. Those count as Column B because residency on the date of receipt controls.
The mistake is excluding unemployment thinking it is “tax-free.” NC fully taxes unemployment. The consequence is an unreported income notice.
A misconception is that the federal exclusion that existed in 2020 still applies. It does not.
Part B, Lines 15 and 16: Social Security Benefits and Other Income
Line 15 is Social Security; Column A is Form 1040 Line 6b, Column B is $0 because NC does not tax Social Security. Line 16 is the catch-all for items like jury duty, hobby income, gambling winnings, and prize income.
NC gambling winnings are NC-source in Column B even for nonresidents. Janet Park won $5,000 at an NC casino while still a Virginia resident; that $5,000 lands in Column B.
The edge case for Line 16 is digital asset income reported on the federal return. Source it like other intangibles — to residency on the receipt date.
The mistake is putting Social Security in Column B. The consequence is overpaying NC tax on income NC does not tax.
The misconception is that small “miscellaneous” amounts can be skipped. NCDOR matches federal totals, so skipping one line breaks the cross-check.
Part B, Line 17 (a–e): Total Additions
Lines 17a through 17e collect NC additions to federal income. Common items include the federal bonus depreciation add-back, Section 179 add-back, and certain deductions NC does not allow.
If you populate Line 17e (Other Additions), you must attach Schedule PN-1 detailing each addition. Aisha Patel adds back $2,000 of federal bonus depreciation on Line 17a.
The edge case is the PTET addition for owners of electing pass-through entities. It runs through Line 17e with PN-1.
The mistake is forgetting to add back items that NC does not conform to. The consequence is an automatic adjustment that increases NC tax.
The misconception is that “Other Additions” is a free-form line. NCDOR requires the PN-1 detail or it disallows the entry.
Part B, Lines 18 and 19 (a–h): Total Deductions
Lines 18 and 19 capture NC deductions, including the Bailey retirement exclusion, the $35,000 military retirement exclusion, and the disaster relief subtractions.
Line 19h (Other Deductions) requires PN-1 detail just like Line 17e. Marcus Reed, a 25-year retired Master Sergeant, deducts his entire military pension under N.C. Gen. Stat. § 105-153.5(b)(11).
The edge case is the Bailey benefit, available only to taxpayers vested in a qualifying plan as of August 12, 1989.
The mistake is double-deducting on both Schedule S and Schedule PN. The consequence is an NCDOR adjustment letter.
The misconception is that all military pay is tax-free. Active-duty pay rules differ from retirement pay rules, and only certain categories qualify.
Part B, Lines 20 and 21: Total Income from All Sources / Total Income from N.C. Sources
Line 20 sums Column A across Lines 3 through 19. Line 21 sums Column B the same way.
These two totals feed Part C. Janet Park totals $120,000 on Line 20 Column A and $48,000 on Line 21 Column B.
The edge case is negative totals from large losses; carry the negative through, do not floor at zero.
The mistake is adding instead of subtracting deductions. The consequence is an inflated taxable percentage on Line 24.
The misconception is that Lines 20 and 21 must match the federal AGI. They will not — Schedule PN includes NC-specific additions and deductions.
Part C, Lines 22, 23, and 24: Taxable Percentage
Line 22 carries the Column B Line 21 amount. Line 23 carries the Column A Line 21 amount. Line 24 divides Line 22 by Line 23 and expresses the result as a decimal carried to four places.
For example, Janet Park divides $48,000 by $120,000 and enters 0.4000 on Line 24, then writes 0.4000 on Form D-400 Line 13. That decimal multiplies her Line 12b NC taxable income to give Line 14, which is then taxed at 4.25% on Line 15.
The edge case is a result above 1.0000 — possible when NC additions push Column B above Column A. Cap at 1.0000; the D-401 instructions require it.
The mistake is rounding to two decimal places. The consequence is a tax difference of hundreds of dollars and a recalculation notice.
The misconception is that Line 24 is a simple time-based fraction (months in NC ÷ 12). It is income-based, not time-based, as Intuit’s TurboTax community thread on NC allocation explains.

How to File the Completed Form
Schedule PN never travels alone — it always attaches to Form D-400. Pick a channel based on your comfort level, time pressure, and whether you owe or expect a refund.
By mail with a refund or no payment: send the package to N.C. Department of Revenue, P.O. Box R, Raleigh, NC 27634-0001. By mail with payment: send to N.C. Department of Revenue, P.O. Box 25000, Raleigh, NC 27640-0640, with a check made payable to N.C. Department of Revenue and Form D-400V attached. Postage is your responsibility, certified mail is $4.85, and the postmark date controls timeliness.
By eFile through an NCDOR-approved provider: no separate filing fee from NCDOR, though the provider may charge $0 to $60. Acknowledgment usually arrives within 24 to 48 hours. Keep the IRS and NC e-file confirmation numbers as your proof of filing.
By tax professional: a CPA or enrolled agent files electronically through professional software. Fees range from $200 to $600 for a part-year return with Schedule PN. Demand a signed Form 8879 equivalent and a copy of the NC e-file acceptance.
In person at a NCDOR Service Center: drop off paper returns Monday through Friday, 8:00 a.m. to 5:00 p.m. Bring two copies — one stamped Received by the clerk is your proof. Payment by check, money order, or in-person card (with a 2% convenience fee through the third-party processor).
Direct payment online: pay through NCDOR’s online payment portal by bank draft (no fee) or credit card (about 2% fee). Save the confirmation page as a PDF.
Processing time runs 6 to 8 weeks for paper and 2 to 3 weeks for e-file, per NCDOR’s published timelines.
What Happens After You File
NCDOR routes the return through automated matching first. The system cross-checks your federal AGI, W-2 totals, and 1099 totals against IRS data. A clean match moves your refund into the payment queue.
If something does not match, NCDOR sends a Notice of Individual Income Tax Assessment or a Request for Information by U.S. mail. You have 45 days to respond. Ignore the notice and the proposed assessment becomes final, with collection action to follow.
Refunds direct-deposit within 2 to 3 weeks of e-file acceptance, or arrive by paper check within 6 to 8 weeks. You can track status at Where’s My Refund. Balances due accrue interest from April 15, 2026 forward at the rate set quarterly under N.C. Gen. Stat. § 105-241.21.
If you discover an error, file an amended return on Form D-400 with the Amended Return circle filled in, attach a corrected Schedule PN, and include a written explanation. Amended returns generally must be filed within 3 years of the original due date or 2 years of payment, whichever is later.
Mistakes to Avoid When Filling Out the Form
- Using a 12-month proration instead of actual income by date. The consequence is a wrong Line 24 decimal and a recalculated tax bill.
- Skipping Schedule PN-1 when Line 17e or Line 19h has a number. The consequence is a return NCDOR cannot process.
- Forgetting to enter the NC residency date range on Part A. The consequence is NCDOR defaulting you to nonresident with no allocation, often causing higher tax.
- Putting Social Security in Column B. The consequence is overpaying NC tax on income NC does not tax.
- Allocating wages by 6/12 rather than W-2 Box 16. The consequence is a mismatch flagged by the W-2 cross-check.
- Reporting NC pension to a former resident. The consequence is violating federal law under 4 U.S.C. § 114 and overpaying.
- Rounding Line 24 to two decimals. The consequence is a tax variance large enough to trigger an adjustment.
- Sending a photocopy instead of the original Web-Fill or Handwritten form. The consequence is rejection by the scanner.
- Using red ink or pencil. The consequence is a return the scanner cannot read, sent back for re-execution.
- Mailing without Form D-400 attached. The consequence is an orphan schedule that NCDOR cannot apply to any taxpayer.
- Claiming the credit for tax paid to another state without attaching that state’s return. The consequence is denial of the credit.
- Filing Schedule PN when both spouses were full-year NC residents. The consequence is unnecessary processing delay while NCDOR sorts the issue.
Dos and Don’ts
- Do download the current Web-Fill PDF directly from ncdor.gov, because revision dates change yearly.
- Do compute Column B by actual receipt date, since NC sources income by residency on the day it is received.
- Do attach W-2s and 1099s showing NC withholding, because NCDOR requires them to release withholding credits.
- Do keep a PDF copy of the entire packet for at least 3 years, since that is the assessment statute of limitations.
- Do double-check that Line 24 carries the exact decimal to Form D-400 Line 13, because the two must tie.
- Do sign and date the bottom of Form D-400, since an unsigned return is treated as not filed.
- Don’t staple — clip — the schedules to the D-400, because staples jam the agency scanner.
- Don’t use dollar signs, commas, or pencil, since the form processor rejects them.
- Don’t mix tax years on a single packet, because each tax year has its own D-400.
- Don’t forget Schedule S when you have NC additions or deductions outside of Schedule PN-1’s scope, because the two schedules cover different items.
- Don’t claim Bailey retirement on Schedule PN; claim it on Schedule S, since Schedule PN handles allocation, not exclusion.
- Don’t paper-file when you can e-file, because e-file cuts processing time by more than half.
Pros and Cons of Filing on Your Own vs. With Help
| Filing on Your Own | Filing With a Tax Professional |
|---|---|
| Costs $0–$60 through e-file software | Costs $200–$600 per return |
| Full control over every entry | Professional spots edge cases (Bailey, MSRRA, PTET) |
| Software guides Line 24 math | Pro signs the return and stands behind it |
| Direct interaction with NCDOR if questions arise | Pro handles NCDOR notices on your behalf |
| Faster turnaround for simple moves | Better for multi-state, K-1, or rental fact patterns |
| Risk of misallocating wages or pensions | Lower audit risk on complex allocations |
| You learn your tax picture deeply | Saves hours during a stressful season |
Pro side: e-file software like TurboTax, H&R Block, and FreeTaxUSA handles Schedule PN automatically, math errors are unlikely, and you keep your information private. Pro side for hiring help: a CPA or enrolled agent brings audit defense, edge-case knowledge, and peace of mind in messy years like a mid-year move plus a property sale.
Con side of going alone: software does not always catch Bailey eligibility, MSRRA elections, or proper K-1 sourcing, and you carry the audit risk yourself. Con side of hiring help: cost, scheduling friction during peak season, and the need to gather every document anyway.
Schedule PN vs. Schedule S — Side-by-Side
| Schedule PN | Schedule S |
|---|---|
| Allocates income between NC and elsewhere | Lists NC additions and deductions |
| Required for part-year residents and nonresidents | Required when you have any NC adjustment |
| Output is the Line 24 decimal | Output is dollar adjustments to D-400 Lines 7 and 9 |
| Companion form is Schedule PN-1 | Pulls from Form D-400TC and others |
Key Agencies and Statutes That Interact with Schedule PN
The North Carolina Department of Revenue administers Schedule PN, processes the return, and issues refunds or assessments. The Internal Revenue Service supplies the federal AGI baseline that flows into Column A. The Social Security Administration drives the name/SSN match. The North Carolina General Assembly writes the statutes that govern sourcing — primarily N.C. Gen. Stat. § 105-153.4 for part-year/nonresident taxable income and § 105-153.5 for additions and deductions.
The federal Bailey v. State of North Carolina settlement, implemented through the NCDOR Bailey decision page, continues to control whether certain government retirees deduct their pensions on Schedule S. The Servicemembers Civil Relief Act and the Military Spouses Residency Relief Act protect military residency claims and feed straight into Part A.
NCDOR Directive PD-14-1 and later guidance address sourcing nuances for telework and pass-through allocations; check the NCDOR Directives library for the latest interpretations before filing a complex return.
FAQs
Do I need to file Schedule PN if I lived in NC all year?
No. Full-year NC residents do not file Schedule PN. The schedule allocates income for part-year residents and nonresidents only, and attaching it unnecessarily can delay processing.
Do I file Schedule PN if my spouse moved to NC mid-year but I did not?
Yes. If either spouse on a joint return was a part-year resident or nonresident, the joint return must include Schedule PN to allocate the couple’s income.
Is Line 24 a time-based or income-based percentage?
No, it is not time-based. Line 24 divides Column B income by Column A income, so it reflects actual NC-source dollars, not months in NC.
Do I write my maiden name or married name in the header?
No maiden name unless that is what is on file with SSA. Use the exact name shown on your Social Security card to avoid an SSN/name-match hold.
Do I include Social Security benefits in Column B?
No. NC does not tax Social Security, so Column B for Line 15 is $0 even if you received benefits while an NC resident.
Do I report my pension to NC after I moved out?
No. Federal law in 4 U.S.C. § 114 bars NC from taxing the retirement income of a former resident, so Column B is $0.
Do I have to attach Schedule PN-1?
Yes, if Line 17e or Line 19h has any amount. Attach both pages of PN-1 even if only one part is used, or NCDOR may be unable to process the return.
Do nonresidents pay NC tax on gambling winnings from an NC casino?
Yes. NC sources gambling income to where the wager was placed, so the winnings go in Column B and into the taxable percentage.
Do I round Line 24 to two decimals?
No. Carry Line 24 to four decimal places. Rounding to two decimals shifts the tax by enough to trigger an NCDOR recalculation.
Do I file a paper Schedule PN if I e-file Form D-400?
No. When you e-file, the schedule transmits with the return automatically. Mailing a paper copy after e-filing creates duplicate records.
Do I include a P.O. Box for the residency address?
Yes, if that is your only mailing address, but enter the physical address on the D-400. NCDOR uses physical addresses to verify residency dates.
Do military servicemembers always file Schedule PN?
No. A servicemember whose state of legal residence stays elsewhere under SCRA does not become an NC resident just by being stationed here, and the spouse may also keep out-of-state residency under MSRRA.
Do I attach W-2s and 1099s to Schedule PN?
Yes. Attach every W-2 and 1099 that shows NC withholding. NCDOR will not release withholding credits without the supporting documents.
Do I file Schedule PN if I only had a few days of NC income?
Yes. Any NC-source income, no matter how small, requires Schedule PN if you are not a full-year resident, because there is no de minimis exception.
Do I have to use blue or black ink on the handwritten form?
Yes. Red ink, pencil, dollar signs, and commas all confuse the scanner, and the return will be returned for re-execution.
