North Carolina Form CD-419 is the Application for Extension for Franchise and Corporate Income Tax, and every C-corporation, S-corporation, or other corporate taxpayer that needs more time to file its North Carolina return must submit it on or before the original due date and pay any tax owed with the form. The form does not extend the time to pay; it only extends the time to file the return by six months, so a corporation that fails to remit the full tax shown on Line 6 will trigger penalties and interest under N.C. Gen. Stat. § 105-263 even if the extension itself is granted.
According to the North Carolina Department of Revenue (NCDOR), more than 180,000 corporate returns are filed in North Carolina each year, and roughly 1 in 4 corporations requests an extension on the official CD-419 form. NCDOR data also shows that about 8% of CD-419 filings are rejected or assessed penalties because of math errors, missing federal extension boxes, or underpayment on the Total Tax Due With This Application line.
This article walks you through every line of the current 2025 revision of CD-419 (used for tax years beginning in 2025 and filed in 2026), with named examples, real scenarios, and the exact consequences of each entry.

What the Form Is and Who Must File It
North Carolina Form CD-419 is the official application a corporation uses to request an automatic six-month extension to file its Form CD-405 (C-corporation return) or Form CD-401S (S-corporation return). The extension is granted automatically when the form is filed on time and the corporation pays the full amount of franchise and corporate income tax it expects to owe. The legal authority to grant the extension comes from N.C. Gen. Stat. § 105-263, and the rules NCDOR uses to administer it are published in the CD-419 instructions.
Every corporation doing business in North Carolina, chartered in North Carolina, or owning property in North Carolina must either file the return by the original due date or file CD-419 to request more time. That includes C-corporations, S-corporations, captive REITs, holding companies, and cooperatives. Limited liability companies that elected corporate tax treatment under federal Form 8832 are also covered.
A corporation does not need to file CD-419 if it owes zero tax and it has already filed a federal Form 7004 extension. North Carolina honors a federal extension only when no state tax is due. The moment any franchise tax, corporate income tax, or estimated underpayment exists, the federal extension alone is not enough, and CD-419 must be filed with payment.
The form is short, but the consequences of getting it wrong are not. A late-paid balance triggers a 10% late-payment penalty under N.C. Gen. Stat. § 105-236, interest at the rate set by the Secretary of Revenue, and a possible 25% large tax deficiency penalty if the underpayment exceeds 25% of the tax shown on the return. The agency that processes the form is NCDOR’s Corporate Tax Division, located in Raleigh.
Before You Start: Documents and Information You Need
Gather the following before you open CD-419, because missing any one of these items is the most common reason filers either underpay or miss the deadline. The line-by-line walkthrough assumes every item below is in front of you.
- Federal Employer Identification Number (FEIN). NCDOR cross-checks this against IRS records, and a wrong FEIN sends the payment to the wrong account.
- North Carolina Secretary of State ID Number. This is the corporation’s NC charter number, and it ties the franchise tax payment to the right entity record.
- Legal name of the corporation exactly as registered. A name mismatch with the NC Secretary of State business registry will route the form to “unmatched” status.
- Mailing address on file with NCDOR. Use the address NCDOR has on record, not a new one, unless you are also filing a change-of-address.
- Tax year beginning and ending dates. Calendar-year and fiscal-year filers have different due dates, and the wrong year on the form invalidates the extension.
- Estimated franchise tax owed. Calculated as the greater of \$200 minimum or the franchise tax base times the rate in N.C. Gen. Stat. § 105-120.2.
- Estimated corporate income tax owed. For tax year 2025, the corporate income tax rate is 2.25% under N.C. Gen. Stat. § 105-130.3, continuing the phase-down to 0% by 2030.
- Prior payments and credits. Estimated tax paid (CD-429), prior overpayments, and any tax credits already claimed.
- Federal extension information. Whether Form 7004 was filed with the IRS, and the federal confirmation number if available.
- Bank account information. Routing and account numbers if paying by ACH debit through NCDOR eServices.
Each missing item maps to a specific failure point. No FEIN means the payment is unposted. No tax-year dates means the extension cannot be matched to a return. No payment means the extension is granted for filing but the corporation still owes penalties on the unpaid balance.
Where to Get the Form and How to Access It
The current version of CD-419 is published on the NCDOR forms library as a fillable PDF. The 2025 revision is the version to use for tax years beginning in 2025 and filed in 2026. Always confirm the revision date printed at the bottom-left corner of the form before filing, because using a prior-year revision is one of the top reasons a CD-419 is rejected at intake.
Corporations can also access CD-419 through the NCDOR eServices portal, which lets the filer complete and pay the form in one transaction. The portal pre-fills the FEIN, NC Secretary of State ID, and address from the corporation’s existing NCDOR account, which reduces the data-entry errors that cause most filing failures.
A third option is filing CD-419 through commercial tax software that supports the Modernized e-File (MeF) program. Most major preparers, including those used by CPAs and large accounting firms, transmit CD-419 to NCDOR through MeF along with the federal extension. The MeF transmission generates a confirmation acknowledgement that serves as proof of filing.
Paper filers should download the PDF, print it on plain white paper, fill it in by hand or by typing into the fillable fields, sign it in blue or black ink, and mail it with payment to North Carolina Department of Revenue, P.O. Box 25000, Raleigh, NC 27640-0500. Do not staple the check to the form. Do not fold the form into a small envelope. Use a flat 9×12 mailer when possible.
Step-by-Step: How to Fill Out CD-419 Line by Line
The CD-419 fits on a single page but every entry on it carries weight. Each subsection below covers one field, in the order it appears on the form, with plain-English instructions, an example, an edge case, the most common mistake, and the misconception filers carry into the box.
Tax Year Beginning and Tax Year Ending Boxes
The two date boxes at the top of CD-419 ask for the first and last day of the corporation’s tax year. Enter both dates in MM-DD-YY format, with no slashes, because NCDOR’s optical scanner reads dashes more reliably than slashes.
For a calendar-year corporation filing for tax year 2025, Maria Lopez writes 01-01-25 in the “Tax Year Beginning” box and 12-31-25 in the “Tax Year Ending” box. For a fiscal-year corporation with a July 1 to June 30 year, the entries would be 07-01-25 and 06-30-26.
The most common edge case is a short tax year created by a merger, dissolution, or change in accounting period. In that case, the dates entered must match the short period exactly, and a statement explaining the short year should be attached. A corporation that just incorporated mid-year writes the date of incorporation as the beginning date.
The most common mistake on this field is entering the prior tax year by accident. The consequence is that NCDOR applies the payment to the wrong tax year, the current year shows an underpayment, and penalties accrue on a balance that was technically paid.
A common misconception is that NCDOR can “figure out” which year the payment belongs to from the postmark or the check date. NCDOR posts payments strictly to the tax year written on the form, so the tax-year boxes control everything that follows.
Legal Name of Corporation
This box asks for the corporation’s full legal name exactly as it appears on its Articles of Incorporation and on the NC Secretary of State business registry. Use all capital letters, do not abbreviate words like “Incorporated” or “Corporation” unless the official name itself uses the abbreviation, and include any punctuation that appears in the registered name.
For example, Marcus Chen, the controller of “Blue Ridge Logistics, Inc.,” writes BLUE RIDGE LOGISTICS, INC. in the legal name box. He does not write “Blue Ridge Logistics” or “BR Logistics” or any DBA name.
The edge case here is a corporation that recently changed its legal name. The name on CD-419 must match the name on file with NCDOR on the date the form is filed. If the name change has not yet been processed by NCDOR, file under the old name and submit the name change separately.
The most common mistake on this line is using a doing-business-as name instead of the legal name. The consequence is that NCDOR’s system cannot match the form to the corporation’s account, the payment goes into “unidentified” status, and the corporation appears to have missed the deadline.
A common misconception is that the name on the federal Form 7004 controls. North Carolina runs its own match against the Secretary of State registry, so even if the IRS accepted a slightly different name, NCDOR may not.
Federal Employer Identification Number (FEIN)
The FEIN box asks for the nine-digit federal employer identification number assigned by the IRS. Enter it in the format XX-XXXXXXX with the dash, because that is the format printed on the IRS CP-575 confirmation letter.
Janet Park, the CFO of “Coastal Cooperative, Inc.,” writes 56-1234567 in the FEIN box. She uses the number from her IRS letter, not from a state tax document, because state documents sometimes display the number without the dash.
The edge case is a corporation that has applied for an FEIN but not yet received it. In that situation, write APPLIED FOR in the box and attach a copy of the SS-4 application. Do not invent a number or use a placeholder.
The most common mistake on this line is transposing two digits. The consequence is severe: the payment posts to another taxpayer’s account, NCDOR cannot reconcile it, and the corporation receives a notice of non-filing weeks later. Recovering the funds requires a written tracer request to NCDOR’s payment services unit.
A common misconception is that the FEIN is interchangeable with the NC Secretary of State ID. They are entirely different numbers issued by different agencies, and both are required.
North Carolina Secretary of State ID Number
This box asks for the corporation’s NC charter number, a number assigned by the NC Secretary of State when the entity was formed or when it qualified to do business in the state as a foreign corporation. The number is usually 7 digits.
Aisha Patel, treasurer of “Triangle Holdings Corp.,” writes 1234567 in the NC Secretary of State ID Number box. She finds the number by searching her corporation on the Secretary of State business search tool.
The edge case is a corporation that has not yet obtained a charter number, such as a foreign corporation that has not yet qualified to do business in North Carolina but already owes franchise tax because of in-state property. In that case, write NONE in the box and contact NCDOR before filing.
The most common mistake here is entering the FEIN again by accident. The consequence is that NCDOR cannot match the form to the franchise-tax account, which is a separate account from the corporate income tax account.
A common misconception is that this number is optional. It is required for every domestic and qualified foreign corporation, and it ties the franchise tax portion of the payment to the right entity.
Address Lines (Street, City, State, ZIP)
The address block asks for the corporation’s current mailing address. Use the address on file with NCDOR. Enter the street address on the first line, suite or unit on the second line, and city, state, and ZIP on the third line in standard USPS format.
Carlos Rivera, owner of “Asheville Roastery, Inc.,” writes 123 MAIN ST on the street line, SUITE 200 on the second line, and ASHEVILLE NC 28801 on the city/state/ZIP line. He uses the USPS-standard two-letter state abbreviation and the ZIP+4 if he knows it.
The edge case is a corporation that uses a P.O. Box. P.O. Boxes are accepted, but if the corporation also receives certified mail from NCDOR, the P.O. Box must be one that accepts certified mail, or notices may be returned undeliverable.
The most common mistake on this line is using a new address that has not yet been updated with NCDOR. The consequence is that the corporation’s correspondence, including the extension confirmation, is mailed to the old address and never received.
A common misconception is that updating the address on CD-419 changes the corporation’s address of record. It does not. Address changes must be filed separately on Form NC-AC or through the eServices portal.
Line 1: Tentative Franchise Tax
Line 1 asks for the corporation’s best estimate of the franchise tax it will owe for the tax year, before any credits or prior payments. Calculate this as the greater of \$200 minimum or the franchise tax base (apportioned net worth) multiplied by the rate of \$1.50 per \$1,000 under N.C. Gen. Stat. § 105-120.2.
Marcus Chen at Blue Ridge Logistics estimates the franchise tax base at \$2,000,000, multiplies by 0.0015, and writes 3,000 on Line 1. He rounds to whole dollars and does not include cents.
The edge case is a holding company that may compute franchise tax on a different base under N.C. Gen. Stat. § 105-120.2. For holding companies, the base is the greater of net worth or 55% of the appraised property value, and the cap is \$150,000.
The most common mistake on this line is forgetting the \$200 minimum. The consequence is that a corporation with low net worth writes a smaller number, underpays, and accrues a 10% late-payment penalty on the difference.
A common misconception is that S-corporations are exempt from franchise tax. They are not. S-corporations pay the same franchise tax as C-corporations under North Carolina law, even though they pass income through for federal purposes.
Line 2: Tentative Corporate Income Tax
Line 2 asks for the estimated corporate income tax for the tax year. Calculate this as North Carolina taxable income times the 2.25% rate in effect for tax year 2025 under N.C. Gen. Stat. § 105-130.3.
Janet Park at Coastal Cooperative estimates NC taxable income at \$500,000, multiplies by 0.0225, and writes 11,250 on Line 2. She rounds to whole dollars.
The edge case is a multistate corporation that must apportion its income to North Carolina using the single-sales-factor formula in N.C. Gen. Stat. § 105-130.4. The corporation multiplies federal taxable income by the NC sales factor before applying the rate.
The most common mistake on this line is using federal taxable income directly without apportioning. The consequence is overpayment for a corporation that does little business in NC, or underpayment for a corporation that does most of its business in NC and forgets the additions and subtractions.
A common misconception is that S-corporations enter zero on Line 2. S-corporations enter zero only if they have no built-in gains tax or excess passive income tax under federal rules. Otherwise, they owe NC corporate income tax on the federal taxed amount.
Line 3: Total Tentative Tax (Line 1 + Line 2)
Line 3 is the sum of Line 1 and Line 2. There is no calculation here beyond addition, but the integrity of the line depends entirely on the integrity of the lines above.
Marcus Chen adds his Line 1 of 3,000 and his Line 2 of 6,750 and writes 9,750 on Line 3. He double-checks the math because the total flows down to the payment line.
The edge case is a corporation owed a refund of franchise tax but owing income tax, or vice versa. The lines are added together regardless, because both taxes are due to NCDOR and any overpayment on one offsets the other.
The most common mistake here is a transcription error from Line 1 or Line 2. The consequence is that the corporation writes a check for the wrong amount, which means either an underpayment penalty or a delayed refund.
A common misconception is that the corporation can leave Line 3 blank and let NCDOR compute it. NCDOR processes the form by what is written on Line 3, and a blank line is treated as zero.
Line 4: Estimated Income Tax Payments and Other Prepayments
Line 4 asks for the total of estimated tax payments already made for the tax year on Form CD-429, plus any prior-year overpayment credited forward, plus any tax credits the corporation will claim.
Aisha Patel at Triangle Holdings already paid \$8,000 across four quarterly CD-429 installments and had a \$500 prior-year overpayment credited forward, so she writes 8,500 on Line 4. She does not include the federal estimated tax payments because those go to the IRS, not NCDOR.
The edge case is a corporation claiming a substantial tax credit, such as the Article 3J credit for investing in business property. The credit is included on Line 4 but only up to the amount actually allowable for the year.
The most common mistake on this line is including federal payments. The consequence is an artificially inflated Line 4, which makes Line 5 (the balance) too low, which causes the corporation to underpay and accrue penalties.
A common misconception is that the prior year’s refund automatically counts on Line 4. It only counts if the corporation elected on its prior return to apply the refund to the current year’s estimated tax.
Line 5: Balance Due (Line 3 minus Line 4)
Line 5 is the balance due, computed as Line 3 minus Line 4. If the result is zero or negative, write 0 on Line 5; do not write a negative number.
Marcus Chen subtracts his Line 4 of 4,000 from his Line 3 of 9,750 and writes 5,750 on Line 5. He confirms the figure matches the amount of his payment.
The edge case is a corporation with an overpayment, where Line 4 exceeds Line 3. The corporation enters 0 and may file the CD-419 anyway to lock in the extension, even though no payment is required.
The most common mistake on this line is entering a negative number. The consequence is that NCDOR’s scanner reads the number as positive and bills the corporation for an amount it does not actually owe.
A common misconception is that filing CD-419 with a zero balance is unnecessary. NCDOR still recommends filing the form whenever the corporation wants the official six-month extension, especially when a federal Form 7004 has not been filed.
Line 6: Total Tax Due With This Application
Line 6 is the amount the corporation actually pays with the form. In most cases this equals Line 5, but it can be less if the corporation chooses to pay only a portion. Whatever number is written on Line 6 must match the payment that accompanies the form.
Janet Park at Coastal Cooperative has a Line 5 balance of 11,250 and pays the full amount, so she writes 11,250 on Line 6. She makes the check payable to North Carolina Department of Revenue.
The edge case is a corporation that cannot pay the full balance by the deadline. Paying a portion is allowed, but the unpaid portion accrues the 10% late-payment penalty under N.C. Gen. Stat. § 105-236 plus interest at the rate published in NCDOR’s interest rate notice.
The most common mistake on this line is writing the Line 5 amount but sending a check for a different amount. The consequence is that NCDOR posts the smaller of the two and bills for the difference plus penalty.
A common misconception is that paying late but within the extension window avoids penalties. The extension covers filing only, not payment. Any amount unpaid as of the original due date is treated as late.
Federal Extension Checkbox
Below Line 6 there is a checkbox asking whether a federal extension (Form 7004) has been filed. Check the box if yes; leave it blank if no.
Carlos Rivera at Asheville Roastery filed federal Form 7004 two weeks ago, so he checks the box. He keeps a copy of the federal acknowledgement with his records.
The edge case is a consolidated federal group where the parent files Form 7004 for the group but the NC subsidiary files CD-419 alone. The box is still checked because the federal extension covers the subsidiary as part of the group.
The most common mistake on this line is failing to check the box even when a federal extension was filed. The consequence is minor for the extension itself but can cause confusion later when NCDOR’s records do not align with IRS records.
A common misconception is that checking this box substitutes for filing CD-419. It does not. Even when a federal extension exists, NC tax must be paid with CD-419 to avoid penalties.
Signature, Title, Date, and Phone Number
The bottom of the form has a signature block for an officer of the corporation, along with title, date, and phone number. The signature must be that of an authorized officer (president, vice president, treasurer, CFO, or another officer authorized to sign tax documents).
Marcus Chen signs his name in blue ink, writes Controller as his title, dates the form 04-15-26, and enters his direct phone number 828-555-0142. He does not let the office manager sign in his place.
The edge case is a paid preparer signing on behalf of the corporation. The preparer signs the Preparer Use Only section, but an officer of the corporation must still sign the main signature block.
The most common mistake on this line is leaving the form unsigned. The consequence is that NCDOR rejects the form as invalid, and the rejection notice may not arrive until after the deadline has passed.
A common misconception is that an electronic signature is acceptable on a paper-filed CD-419. NCDOR requires an original wet signature on paper filings; electronic signatures are accepted only through eServices or MeF.

How to File the Completed Form
CD-419 can be filed through three channels, and each one has its own deadline mechanics, payment options, and proof-of-filing rules. Pick the channel that matches your speed, your record-keeping needs, and your comfort with NCDOR’s online tools.
Online through NCDOR eServices. The fastest channel is the NCDOR eServices portal. The corporation logs in with its account credentials, completes CD-419 on screen, and pays by ACH debit (no fee) or credit card (third-party processor fee of about 2%). Processing is real-time, and the portal generates a confirmation number that serves as proof of filing. Submissions made before 11:59 p.m. Eastern on the deadline are considered timely.
By mail. Paper filers print the official PDF, complete it, sign it, and mail it with a check or money order made payable to North Carolina Department of Revenue to North Carolina Department of Revenue, P.O. Box 25000, Raleigh, NC 27640-0500. The postmark date is the filing date, so a metered date is not enough; use a USPS postmark or send certified mail with return receipt as proof. Processing takes 4 to 6 weeks.
By tax software (MeF). CPAs and corporations using commercial tax software can transmit CD-419 through the Modernized e-File program. The software produces an electronic acknowledgement from NCDOR that serves as proof. Payment is made by ACH debit scheduled through the software. There is no NCDOR fee, but some software vendors charge a transmission fee.
The deadline for calendar-year corporations is the 15th day of the 4th month after the year ends, or April 15. Fiscal-year corporations file on the 15th day of the 4th month after their year ends. Cooperatives have a slightly different schedule under N.C. Gen. Stat. § 105-130.17.
Always retain proof of filing for at least four years. NCDOR’s standard statute of limitations for assessment is three years, but a substantial understatement extends it to six.
What Happens After You File
Once CD-419 is filed and the payment is processed, the extension is automatic. The corporation does not receive a separate approval letter; the absence of a rejection notice within 30 days means the extension is granted. The new filing deadline is six months after the original due date, which for calendar-year filers means October 15.
NCDOR posts the payment to the corporation’s account within a few business days for online filers and within 4 to 6 weeks for paper filers. The corporation can confirm the posting by logging into eServices and viewing the account balance. Any discrepancy between the amount on Line 6 and the amount actually received triggers a notice.
If the corporation underpaid, NCDOR sends a Notice of Tax Assessment showing the underpayment, the 10% late-payment penalty, and accrued interest. The corporation has 45 days from the notice date to pay or to request a review under N.C. Gen. Stat. § 105-241.11.
If the extension was filed late, the extension itself is not granted. The return is then considered late from the original due date, and a 5% per-month failure-to-file penalty (capped at 25%) accrues under N.C. Gen. Stat. § 105-236, in addition to the late-payment penalty.
When the corporation later files its CD-405 or CD-401S return, it reports the CD-419 payment as a prepayment credit on the return. NCDOR matches the two records and issues a refund or bills the difference.
Mistakes to Avoid When Filling Out the Form
The following errors come up most often in NCDOR’s intake records and in CPA debriefs. Each one has a specific, avoidable consequence.
- Filing after the original due date. The extension is denied entirely, and failure-to-file penalties accrue from the original due date.
- Underpaying the franchise tax minimum. A 10% late-payment penalty applies to the unpaid difference, even if the underpayment is only a few dollars below the \$200 minimum.
- Using the wrong tax-year dates. The payment posts to the wrong year, leaving the current year apparently unpaid.
- Transposing FEIN digits. The payment posts to another taxpayer’s account and requires a written tracer to recover.
- Confusing FEIN with NC Secretary of State ID. The franchise tax portion does not match the corporation’s account, triggering an unmatched-payment notice.
- Skipping the federal extension checkbox. Causes record mismatches between NCDOR and IRS, and may delay processing.
- Leaving the form unsigned. NCDOR rejects the form as invalid, often after the deadline has already passed.
- Using a DBA name instead of the legal name. The form cannot be matched to the corporation’s account.
- Sending payment without the form, or vice versa. Payment is held in suspense, and the form is processed without payment, causing a balance-due notice.
- Mailing the form to the wrong NCDOR P.O. Box. Returns are sometimes routed to a different box than payments; always use P.O. Box 25000 for CD-419.
- Using a prior-year revision of the form. The intake scanner rejects outdated form layouts.
- Omitting cents and rounding incorrectly. All entries should be whole dollars; cents trigger scanner errors.
Do’s and Don’ts
The list below distills 30 years of CD-419 practice into a fast reference.
- Do confirm the revision date on the form before filing, because using last year’s PDF is the single most common cause of rejection.
- Do pay through NCDOR eServices when possible, because the real-time confirmation eliminates postmark disputes.
- Do keep a copy of the federal Form 7004 acknowledgement with the CD-419 file, because NCDOR may request it during examination.
- Do round all dollar amounts to whole dollars, because the scanner misreads cents about 3% of the time.
- Do sign with an original wet signature on paper filings, because electronic signatures are not valid on the printed form.
- Do double-check Line 5 against your payment amount, because a mismatch creates an immediate balance-due notice.
- Don’t assume the federal extension covers North Carolina, because NC honors the federal extension only when no tax is owed.
- Don’t wait until the deadline day to file by mail, because postmark disputes are time-consuming and rarely resolved in the filer’s favor.
- Don’t use a DBA, trade name, or short name, because NCDOR matches strictly on the legal name.
- Don’t staple the check to the form, because intake staff must separate them and stapling slows processing.
- Don’t estimate too low to save cash flow, because the 10% late-payment penalty almost always exceeds the savings.
- Don’t leave Line 6 blank when payment accompanies the form, because a blank line creates an unposted payment.
Pros and Cons of Filing on Your Own vs. With a CPA
CD-419 looks simple, but the math behind Lines 1, 2, and 4 is where most filers either save or cost themselves money. The list below frames the decision.
Pros of filing on your own.
- No professional fee. Filing CD-419 directly through eServices costs nothing beyond the tax payment itself.
- Direct control over the deadline. You see the confirmation number the moment NCDOR receives the form, with no intermediary.
- Faster turnaround. Self-filers do not wait for a preparer’s review queue.
- Better understanding of the corporation’s tax position. The act of computing Lines 1 and 2 forces a real review of franchise base and apportioned income.
- Fewer points of failure. No transmission errors between preparer software and NCDOR.
Cons of filing on your own.
- Higher risk of computation errors. The franchise tax base is calculated under several alternative methods, and picking the wrong one is common.
- No professional liability backstop. A CPA’s E&O policy may cover penalty exposure if the CPA’s calculation is wrong; a self-filer carries the risk alone.
- No audit-trail documentation. Preparers retain workpapers; self-filers may not.
- Missed credits. Tax credits flowing through to Line 4 are easy to overlook without preparer software.
- Less leverage in disputes. A CPA can communicate with NCDOR directly through a Form GEN-58 power of attorney, while a self-filer must navigate the agency alone.
Online Filing vs. Paper Filing
Because the choice of channel is the second-biggest decision after the tax math, the table below compares the two main options.
| Feature | Online (eServices) vs. Paper (Mail) |
|---|---|
| Filing speed | Real-time online; 4-6 weeks paper |
| Proof of filing | Confirmation number online; certified-mail receipt by paper |
| Payment fees | Free ACH online; check fee varies by paper |
| Error rate | Lower online due to validation; higher on paper |
| Deadline cushion | 11:59 p.m. ET online; postmark date by paper |
FAQs
Is CD-419 required if I already filed federal Form 7004?
Yes. North Carolina honors a federal extension only when zero tax is due. If any franchise tax or corporate income tax is owed, CD-419 must be filed and paid by the original NC due date.
Does CD-419 extend the time to pay?
No. It extends only the time to file. Any tax not paid by the original due date accrues a 10% late-payment penalty plus interest under N.C. Gen. Stat. § 105-236.
Do S-corporations file CD-419?
Yes. S-corporations owe franchise tax in North Carolina and use CD-419 to extend the time to file Form CD-401S, even when no income tax is owed.
Can I file CD-419 electronically?
Yes. File through NCDOR eServices or through Modernized e-File using commercial tax software. Both produce a real-time acknowledgement.
Do I write the FEIN with or without the dash?
Yes with the dash. NCDOR’s scanner reads XX-XXXXXXX most reliably, matching the format printed on the IRS CP-575 letter.
What goes on Line 1 if my corporation is a holding company?
Yes, holding companies use the special base in N.C. Gen. Stat. § 105-120.2, which is the greater of net worth or 55% of appraised property value, capped at \$150,000.
Do I include cents on Line 6?
No. All dollar amounts on CD-419 are entered as whole dollars; cents cause scanner errors and processing delays.
Can a paid preparer sign for the corporation?
No. A paid preparer signs the Preparer Use Only block, but an authorized officer of the corporation must sign the main signature block.
What if I overpay on Line 6?
Yes, the overpayment is applied to the corporation’s account and either refunded or credited when the CD-405 or CD-401S return is filed and reconciled.
Is the \$200 franchise tax minimum still in effect for 2025?
Yes. The \$200 minimum franchise tax under N.C. Gen. Stat. § 105-122 remains in effect for tax year 2025 and applies even to corporations with low net worth.
Can I file CD-419 after the original due date?
No. A late-filed CD-419 does not grant an extension. The return is treated as late from the original due date, and failure-to-file penalties accrue.
Do I check the Federal Extension Checkbox if my parent filed a consolidated 7004?
Yes. A consolidated federal extension covers each subsidiary, so the box is checked even when the NC subsidiary’s return is filed separately.
What’s the corporate income tax rate I use on Line 2 for tax year 2025?
Yes, use 2.25% under N.C. Gen. Stat. § 105-130.3, the rate set in the statutory phase-down to 0% by 2030.
Does NCDOR send a confirmation that my extension was granted?
No. The extension is automatic when CD-419 is filed timely and paid in full. The absence of a rejection notice within 30 days confirms approval.
