California Form CDTFA-401-2 is the State, Local and District Sales and Use Tax Return used by sellers who operate from non-permanent or temporary selling locations — swap meet vendors, fairground sellers, mobile food trucks, craft fair artisans, and itinerant merchants — to report taxable sales and pay sales and use tax to the California Department of Tax and Fee Administration. Every holder of a temporary or sub-permit seller’s permit who made sales during the reporting period must file this return, even when sales totaled zero.
The form drives the allocation of state tax under Revenue and Taxation Code §6051, local Bradley-Burns tax under §7202, and the patchwork of voter-approved district taxes under the Transactions and Use Tax Law. According to the CDTFA’s most recent Annual Report, California processes more than 1.6 million sales and use tax returns each year, and roughly 8% are flagged for math or allocation errors that trigger a billing notice. Getting this form right the first time saves money, audits, and stress.

What the Form Is and Who Must File It
CDTFA-401-2 is the long-form State, Local and District Sales and Use Tax Return designed for sellers who do not operate from a single fixed retail address. The current revision is dated Rev. 60 (1-24), and you should always confirm the revision printed in the lower-left corner of page 1 before filing. Filers include holders of temporary seller’s permits, sub-permit holders, swap meet operators registered under Regulation 1699, and itinerant vendors selling at multiple California venues during the reporting quarter.
The form is required by Revenue and Taxation Code §6452, which mandates that every retailer file a return for each reporting period whether or not tax is owed. The CDTFA uses the data to distribute the 1% Bradley-Burns local share to the city or county where the sale occurred and to send district tax to each special-tax jurisdiction. A misfiled return does not just create a math error — it sends money to the wrong city, and that triggers reallocation audits under Regulation 1802.
You must file CDTFA-401-2 if you hold a temporary or sub-outlet permit, made sales at non-fixed locations, or were directed to use this form by a CDTFA representative. Sellers with a single fixed place of business typically file the shorter CDTFA-401-EZ or CDTFA-401-A instead. If your gross sales exceeded the threshold set in §6471 — generally measurable monthly tax of $17,000 or more — you must also remit prepayments and reconcile them on this return.
Before You Start: Documents and Information You Need
Open every record before you log in to the CDTFA Online Services portal so you do not have to abandon a half-finished return. The portal times out after about 20 minutes of inactivity, and a dropped session can force you to re-enter every district allocation. Gather these items first.
- CDTFA account number. Your 9-digit account number appears on your seller’s permit and every prior notice; without it you cannot log in or paper-file accurately.
- Reporting period dates. Quarterly filers cover three calendar months; missing the period boundaries causes deposits to be applied to the wrong quarter.
- Gross sales totals by location. Pull point-of-sale tapes, Square or Clover reports, and handwritten receipts so you can prove the Line 1 number under audit.
- Nontaxable and exempt sales detail. Resale certificates, food-for-home-consumption sales, and labor charges all reduce taxable sales but only with backup documentation under Regulation 1668.
- Use tax purchases. Out-of-state purchases used in California — display fixtures, packaging, equipment — must go on Line 2 even if no California vendor charged tax.
- District tax allocation worksheet. A spreadsheet listing each city or unincorporated county where you made sales, with taxable sales for each, prevents Schedule A2 errors.
- Prepayment confirmations. If you remitted prepayments under §6471, pull each CDTFA-1150 confirmation; missing them creates double payment.
- Bad debt records. Any uncollectible accounts written off for income tax purposes can be claimed under Regulation 1642, but only with the customer-by-customer ledger.
- Bank account and routing numbers. ACH debit is the default payment method on the portal; a wrong routing number triggers a returned-payment penalty.
- Prior return. Last quarter’s CDTFA-401-2 helps you carry forward consistent district allocations and catch year-over-year anomalies the auditors look for.
Where to Get the Form and How to Access It
The official PDF lives at the CDTFA forms library, and the fillable version of CDTFA-401-2 is the only version the agency will accept by mail. Do not download copies from third-party tax-blog sites — those PDFs are often older revisions, and the CDTFA scanner rejects forms whose revision code does not match the current quarter’s barcode.
Most filers complete the return inside the CDTFA Online Services portal instead of using the PDF. After logging in with your username and password, choose File a Return next to your sales and use tax account, then select the correct period. The portal pre-populates your name, account number, and reporting period, which removes three of the most common header-error rejections.
If you must paper-file — for example, because the CDTFA mailed you a pre-printed return — write only inside the boxes, use black ink, and never staple checks to the form. Mail the completed return to the address printed on the back of the form, typically California Department of Tax and Fee Administration, PO Box 942879, Sacramento, CA 94279-7072. For walk-in filing, every CDTFA field office accepts returns and payments during posted hours.
Step-by-Step: How to Fill Out CDTFA-401-2 Line by Line
Work the form top to bottom and never skip the schedules first. Each H3 below tracks one field on the official return. Use the exact box numbers and labels printed on the Rev. 60 PDF so an auditor cross-walking your return to the source data sees a clean trail.
Header: Account Number, Period, and Owner Name
The header asks for your 9-digit CDTFA account number, your reporting period in MM/DD/YYYY–MM/DD/YYYY format, and the legal name of the permit holder. Type the number with no dashes and no spaces; the OCR scanner reads only digits. Maria Lopez writes her account as 100-123456 in conversation but enters 100123456 on the form.
If you operate under a DBA, the legal name still goes on the top line and the DBA goes on the second line, exactly as printed on your seller’s permit. A common edge case is a married couple operating jointly under a single permit — both names go on the legal name line in the order shown on the permit. The most common mistake here is entering the period of the prior quarter, which causes the payment to post to a closed period and triggers a delinquency notice for the current quarter. Many filers wrongly believe the header is cosmetic; in fact, the OCR uses it to route the return, and a wrong digit can send your filing into the unidentified-payment queue for weeks.
Line 1 — Total (Gross) Sales
Line 1 asks for every dollar of merchandise you sold during the period, before any deduction. Enter the cumulative gross from all selling locations as a single number, rounded to the nearest dollar. Carlos Nguyen, a swap meet apparel vendor, totals $48,217.43 in receipts and writes 48,217 on Line 1.
Include cash, card, app, and barter sales; include sales tax reimbursement collected from customers under Regulation 1700. The most frequent edge case is a vendor who ran a single sale through a friend’s Square account — that sale still belongs on this line if the merchandise was yours. The biggest mistake is excluding tax reimbursement to “save time,” which understates Line 1 and produces a reconciliation hit when the CDTFA matches Form 1099-K data. A persistent misconception is that tips and gratuities go on Line 1; they do not, unless the tip was mandatory and added to the menu price.
Line 2 — Purchases Subject to Use Tax
Line 2 captures the cost of items you bought tax-free from out-of-state vendors and used in California — display racks, packaging, tools, even some inventory withdrawn for personal use. Enter the cost paid, not the retail value. Aisha Patel, a craft fair jeweler, bought $1,240 in display cases from an Oregon supplier and writes 1,240 on Line 2.
Use tax mirrors sales tax under §6201, so the purchase is taxable at the same combined rate as a sale at the location of first use. The edge case most filers miss is inventory withdrawn for personal or family use — that withdrawal is a taxable use under Regulation 1669. The classic mistake is leaving Line 2 blank because no California vendor invoiced sales tax; CDTFA cross-matches Franchise Tax Board income tax data and assesses use tax with penalty. The misconception that “I paid sales tax somewhere” excuses use tax is wrong unless that other state’s rate equaled or exceeded California’s combined rate.
Line 3 — Total (Add Lines 1 and 2)
Line 3 is the sum of Lines 1 and 2 and represents the gross transactions subject to tax before deductions. Add the two numbers and enter the total; the portal does this math automatically. Carlos’s Line 1 of 48,217 plus Line 2 of 0 yields 48,217 on Line 3.
The edge case is a filer with no taxable gross sales but a taxable use-tax purchase — Line 3 still has a value, and you still owe a return. The common mistake is hand-totaling and transposing digits (“48,127” instead of “48,217”), which throws off every downstream line. The misconception that a zero-sales quarter means a zero-line-3 quarter ignores Line 2; even an empty inventory month can produce use tax.
Lines 4–10 — Deductions From Gross
These lines remove non-taxable amounts from your gross before computing tax. Common deductions include sales to the U.S. Government (Line 4), sales in interstate commerce (Line 5), sales of food products for home consumption (Line 6), labor (Line 7), sales to other retailers for resale (Line 8), bad debts (Line 9), and other deductions identified on Schedule A (Line 10). Marcus Chen, a mobile food truck operator, deducts 12,400 on Line 6 for cold prepackaged food sold for off-truck consumption.
Each deduction has a backup-document rule. Resale deductions need a valid CDTFA-230 on file under Regulation 1668; without it, the deduction collapses on audit. The signature mistake is deducting “labor” for taxable fabrication labor under Regulation 1526; fabrication labor is taxable. A widespread misconception is that hot prepared food is exempt — it is not, even when sold to-go.
Line 11 — Total Nontaxable Transactions
Line 11 is the sum of Lines 4 through 10 and represents every dollar that drops out before tax. Enter the total; the portal calculates it automatically when you e-file. Marcus totals his deductions to 12,400 and writes that on Line 11.
The edge case is a deduction that overlaps two categories — a sale of cold food to the U.S. Government, for example — claim it once, never twice. The mistake of double-claiming a deduction is one of the top three findings in CDTFA office audits. The misconception that “more deductions means lower tax forever” ignores the backup-documentation requirement; an unsupported deduction is added back with interest under §6482.
Line 12 — Transactions Subject to State Tax
Line 12 is Line 3 minus Line 11 and represents the base on which state-level sales and use tax is computed. Enter the difference; the portal performs the subtraction. Carlos’s 48,217 less 0 yields 48,217 on Line 12.
The edge case is a negative Line 12, which only happens with credit balances from prior bad debts or returned merchandise — write 0 and carry the credit on the next quarter’s Line 9. The recurring mistake is not matching Line 12 to the taxable sales number filed on the federal Schedule C; mismatches above 5% draw correspondence audits. The misconception that Line 12 is the figure tax is computed on at the local rate is partly wrong — state tax uses Line 12, but local and district tax can differ when rules treat fixtures and fuel differently.
Line 13 — State Tax (6.00%)
Line 13 multiplies Line 12 by the state rate of 6.00% — a 5.00% general fund rate plus a 1.00% Local Revenue Fund rate authorized under §6051.15. Enter the result rounded to the nearest cent. Carlos’s 48,217 × 0.06 equals 2,893.02 on Line 13.
The edge case is a partial-period rate change; California has not changed the state rate since 2017, but plan for one by checking the current rate page every quarter. The mistake of using 7.25% (the statewide minimum combined rate) instead of 6.00% on Line 13 is one of the most common errors. The misconception that the 1.00% Bradley-Burns is part of Line 13 is wrong; Bradley-Burns goes on Schedule B.
Line 14 — County Tax (¼%)
Line 14 calculates the ¼% county transportation tax authorized by §7202(a). Multiply Line 12 by 0.0025 and enter the result. Carlos’s 48,217 × 0.0025 equals 120.54 on Line 14.
The edge case is sales at a venue straddling two counties; allocate by the physical booth location, never by the customer’s home. The mistake is rounding to the nearest dollar; the portal expects two decimal places. The misconception that this is the same as the local 1.00% Bradley-Burns is wrong — the ¼% is a separate county-level transportation tax.
Schedule A2 — District Tax Allocation
Schedule A2 distributes district transactions and use taxes to each city, county, or special district where you made sales. List each district by code, enter taxable sales for that district, and apply the rate published on the CDTFA District Tax Rates chart. Marcus made 15,200 of taxable sales in the City of Los Angeles and applies the 1.50% combined district rate, yielding 228.00 of district tax.
The most common edge case is sales delivered into a district where you did not physically sell — under §7262, district use tax is based on the address where the customer takes delivery. The most expensive mistake is allocating all district sales to your home city; the CDTFA reallocates under Regulation 1802 and bills the difference to the right city. A persistent misconception is that small vendors are exempt from district tax — there is no de minimis under California law; one $5 sale in a district triggers the obligation.
Schedule B — Local Tax Allocation
Schedule B allocates the 1.00% Bradley-Burns local tax under §7202 to the city or unincorporated county where the sale occurred. Enter taxable sales by jurisdiction code, and the form computes the 1.00% share. Aisha sold 7,800 at a Sacramento craft fair and writes 7,800 next to code 34-998, producing 78.00 in local tax.
The edge case is online sales fulfilled from a temporary booth — those sales allocate to the booth location, not the buyer’s address, under Regulation 1802(a). The classic mistake is allocating every sale to the seller’s home address; that practice is the single biggest reason cities petition the CDTFA for reallocation hearings. The misconception that Bradley-Burns is “city tax” is incomplete — half a percent goes to the county-level transportation pool even when the sale happens inside a city.
Line 15 — Combined State, Local, and District Tax
Line 15 adds Line 13, Line 14, the Schedule B local total, and the Schedule A2 district total. The portal sums them automatically; on paper, double-check the addition. Carlos’s combined tax totals 3,492.74 on Line 15.
The edge case is a partial credit from a return that brought Line 15 below zero — never enter a negative number; carry it forward as a credit. The mistake is summing only Lines 13 and 14 and forgetting the schedules, which understates tax by 1% to 4%. The misconception that Line 15 equals “the tax I collected from customers” is dangerous — you owe Line 15 even if you under-collected at the register, under Regulation 1700.
Line 16 — Excess Tax Collected
Line 16 captures any tax you collected that exceeded the legal rate — for example, charging 9.50% in a 9.00% district. Enter the over-collection amount; you owe it to the state under §6901.5 unless you refund customers. Marcus over-charged 15.00 in tax across one weekend and writes 15.00 on Line 16.
The edge case is voluntary refunds to customers — keep cancelled checks or refund receipts to remove the obligation. The mistake of pocketing excess tax is a misdemeanor under §7153. The misconception that small over-collections “wash out” in rounding is false; CDTFA audits reconstruct the math from POS data.
Line 17 — Total Amount of Tax
Line 17 is Line 15 plus Line 16 and shows the gross tax due before prepayment credits. Enter the sum. Marcus totals 1,540.00 plus 15.00 and writes 1,555.00 on Line 17.
The edge case is a quarter where Line 16 is the only nonzero line — you still owe the excess. The mistake of skipping Line 17 because the portal “auto-calculates” lets typos slip through; review the screen before submitting. The misconception that Line 17 is what you remit ignores prepayment credits on Line 18.
Line 18 — Less Tax Prepayments
Line 18 reduces tax due by amounts you prepaid during the quarter under §6471. Enter the sum of all CDTFA-1150 prepayment confirmations issued during the period. A larger filer who prepaid 2,000 in months one and two enters 4,000 on Line 18.
The edge case is a prepayment posted to the wrong account number; pull the CDTFA-1150 confirmation and contact the field office before filing. The mistake of double-claiming prepayments triggers an automatic billing notice. The misconception that prepayments are optional applies only below the $17,000 monthly tax threshold; above it, prepayment is mandatory.
Line 19 — Remaining Tax Due
Line 19 is Line 17 minus Line 18 and represents the amount you must pay with the return. Enter the difference. Carlos’s 3,492.74 minus 0 equals 3,492.74 on Line 19.
The edge case is a negative Line 19 — that is a credit, not a refund; claim it on next quarter’s return or file CDTFA-101 for a refund. The mistake of under-paying Line 19 produces a 10% penalty under §6591. The misconception that paying Line 17 is enough ignores the credit you already earned through prepayments.
Line 20 — Penalty
Line 20 is the 10% late-filing or late-payment penalty under §6591. Enter 10% of Line 19 if you are filing or paying after the due date; otherwise leave blank. A return one day late on 3,492.74 triggers 349.27 on Line 20.
The edge case is timely filing with late payment — the 10% still applies to the unpaid portion. The mistake of self-assessing 5% (federal-style) is wrong; California’s penalty is 10% from day one. The misconception that an extension waives the penalty applies only to filing, never to payment.
Line 21 — Interest
Line 21 is interest on tax paid late under §6591.5, at the rate posted on the CDTFA Interest Rates page. Multiply Line 19 by the daily rate times the number of days late. A 3,492.74 liability paid 30 days late at the current 12% annual rate is 34.45 on Line 21.
The edge case is partial payments; interest stops accruing on each dollar as it is paid. The mistake of skipping interest because “the bill will come” still produces correct interest, but it triggers a billing notice that complicates clean-record applications for licensing. The misconception that interest is waivable is wrong; only penalty is waivable for reasonable cause under §6592.
Line 22 — Total Amount Due and Payable
Line 22 is the sum of Lines 19, 20, and 21 — the check or ACH total. Enter the grand total. Carlos pays 3,492.74 on time with no penalty or interest, so Line 22 equals 3,492.74.
The edge case is overpayment intentionally remitted to absorb a future liability; do not do this on Line 22, instead file a separate prepayment under CDTFA-1150. The mistake of paying less than Line 22 produces an immediate billing notice with collection-cost add-ons. The misconception that paying through a third-party processor satisfies the obligation is risky; processor delays count against you.
Signature, Date, and Telephone
The signature block requires the owner, partner, corporate officer, or LLC member to sign, date, and provide a daytime phone. The signature certifies the return is true under penalty of perjury per §7152. Maria signs as Maria E. Lopez, Owner, dates the return 04/22/2026, and writes her cell phone.
The edge case is a paid preparer signing — a preparer signature does not replace the owner signature, which still must appear. The mistake of an unsigned return is jurisdictional; the CDTFA treats it as not filed and the late penalty runs until a signed copy arrives. The misconception that an electronic acknowledgement on the portal replaces the signature is correct only if you submitted under your own login.
Three Filled-Out Examples Using Real Scenarios
The three scenarios below show how three real-world filers complete CDTFA-401-2 from header to signature. Each filer used the CDTFA Online Services portal to file Q1 2026.

How to File the Completed Form
You can file CDTFA-401-2 four ways: online, by mail, in person, or — for limited cases — by fax to your assigned field office. Online filing is mandatory for most accounts under §6479.3, and the CDTFA Online Services portal is the only channel that produces an instant filing acknowledgement.
Online. Log in at the portal, choose File a Return, complete each line, and pay by ACH debit, credit card, or ACH credit. ACH debit is free; credit card runs about 2.3% via the Official Payments processor. Processing is real-time, and the system emails a confirmation number — save it as your proof of filing.
By mail. Send the signed paper return with a check payable to California Department of Tax and Fee Administration to CDTFA, PO Box 942879, Sacramento, CA 94279-7072. Use certified mail with return receipt; the postmark date controls timeliness under §6479. Processing takes four to six weeks.
In person. Walk into any CDTFA field office during posted hours with the return and a check, money order, or cashier’s check. Ask the cashier to date-stamp your duplicate copy as proof of filing. Same-day posting; no fee.
By fax. Available only when a CDTFA representative authorizes it for a specific account. The fax number is provided in writing; never assume a public number is acceptable. Keep the fax confirmation page as proof.
What Happens After You File
Within minutes of an online filing, the portal posts a confirmation number and updates your account ledger. Paper returns post in four to six weeks; until then your account shows the period as “expected” rather than “received.” If you owe and paid, the ACH debit clears within 1–3 business days; if it bounces, the CDTFA assesses a returned-payment penalty under §6591(d).
The CDTFA matches every return against Franchise Tax Board income data, IRS Form 1099-K reports, and prior-quarter trends. A mismatch above the agency’s tolerance triggers a CDTFA-1296 audit notice within 6 to 18 months. Keep every supporting record for at least four years per §7053; auditors will ask for invoices, resale certificates, bank statements, and POS reports.
If you discover an error after filing, file an amended return under Regulation 1585 or write to your field office. Amended returns within three years of the original due date can claim refunds; after three years, the statute of limitations under §6902 closes the door.
Mistakes to Avoid When Filling Out the Form
- Wrong reporting period in the header. Money posts to the wrong quarter, generating a delinquency notice for the actual quarter.
- Skipping Line 2 because no California vendor charged tax. CDTFA matches FTB data and bills use tax with penalty.
- Allocating all district sales to your home city. Reallocation under Regulation 1802 shifts tax and triggers correspondence audits.
- Deducting fabrication labor. Fabrication labor is taxable under Regulation 1526; the deduction collapses on audit.
- Forgetting to claim tax prepayments on Line 18. You pay twice and must request a refund through CDTFA-101.
- Pocketing excess tax collected on Line 16. Treated as a misdemeanor under §7153.
- Filing without a valid resale certificate on file. The Line 8 deduction disappears, and you owe tax plus 10% penalty.
- Using the wrong district tax rate. District rates change every April and October; check the CDTFA-105 chart each filing.
- Stapling a check to a paper return. Causes scanner jams and processing delays; CDTFA may misapply your payment.
- Skipping the signature. The return is treated as not filed, and the 10% late-filing penalty keeps running.
- Leaving the phone number blank. Auditors call for clarification, and a missing number forces a written-correspondence audit.
- Rounding inconsistently. Mixing whole-dollar and dollars-and-cents entries produces math mismatches and billing notices.
Do’s and Don’ts
Do file every period — even zero-sales quarters — because non-filing triggers an estimated-billing notice that can exceed actual liability. Do keep four years of records under §7053. Do collect tax-included pricing legibly on every receipt. Do download the district tax rate chart at the start of every quarter. Do use the portal for instant proof of filing. Do request reasonable-cause penalty relief under §6592 when illness or disaster disrupts filing.
Don’t file from a third-party PDF copy of the form — only the official CDTFA PDF is accepted. Don’t allocate all sales to your home address. Don’t assume non-California purchases avoid use tax. Don’t sign on behalf of a co-owner without written authority. Don’t estimate Line 1 — always tie it to POS data. Don’t cancel an ACH debit after submission; it triggers a returned-payment penalty.
Pros and Cons of Filing on Your Own vs. With Help
Filing on your own through the CDTFA Online Services portal is free, instant, and self-paced. Pros: zero professional fees; immediate confirmation; full control over allocations; ability to amend the same way; clear audit trail in your portal account. Cons: every error is your error; no professional liability backstop; you must learn district tax rules; no guidance on edge cases like withdrawn inventory; no representation if an audit follows.
Hiring a CPA or CTEC-registered preparer costs $150–$600 per quarter for a small itinerant seller. Pros: fewer math errors; correct district allocation; preparer-signature audit support; advice on prepayments and bad debts; time savings during peak selling weeks. Cons: ongoing fees; you still sign and remain personally liable; preparers vary widely in sales-tax expertise; some lack CDTFA representation rights; slow turnaround during busy seasons.
CDTFA-401-2 vs. CDTFA-401-A — Which One Do You File?
| Feature | What Differs |
|---|---|
| Primary filer | CDTFA-401-2: itinerant or temporary-permit sellers; CDTFA-401-A: fixed-location retailers |
| Schedules required | CDTFA-401-2: Schedules A2, B, sometimes C; CDTFA-401-A: typically just Schedule A |
| Multi-location allocation | CDTFA-401-2: required by booth/event; CDTFA-401-A: by sub-outlet |
| Online portal default | Both file in the same portal |
| Prepayment treatment | Identical under §6471 |
FAQs
Do I file CDTFA-401-2 if I had zero sales this quarter?
Yes. Every active permit holder must file under §6452; enter zeros and submit. Skipping a zero-sales return triggers an estimated billing and a 10% late-filing penalty.
Can I file CDTFA-401-2 on paper?
Yes, but only if you are not subject to the mandatory e-file rule under §6479.3. Most accounts must e-file. Confirm by logging into the portal first.
Do I write my legal name or DBA on the top line?
No to DBA on the top line. Put the legal name shown on the seller’s permit on the legal-name line; the DBA goes on the second line. The CDTFA matches by legal name.
Do I include sales tax I collected on Line 1?
Yes. Tax reimbursement collected from customers is part of gross under Regulation 1700. Excluding it understates Line 1 and triggers a 1099-K reconciliation.
Do tips go on Line 1?
No, unless the tip was mandatory and added to the menu price. Voluntary gratuities are excluded under Regulation 1603.
Do I owe use tax on display cases bought from out of state?
Yes. Use tax under §6201 applies to fixtures used in California, even when no California vendor charged tax. Report the cost on Line 2.
Do I allocate online sales to the buyer’s address or my booth address?
No to the buyer for in-person delivery; yes to the buyer for shipped delivery. Bradley-Burns under Regulation 1802 allocates by where title passes.
Can I claim a bad debt on Line 9 if I wrote the customer off later?
Yes, but only after writing it off for income tax purposes per Regulation 1642. Keep the customer-by-customer ledger as backup.
Do I include hot prepared food in the Line 6 deduction?
No. Hot prepared food is taxable, even when sold to-go, under Regulation 1603. Only cold food for home consumption qualifies.
Can I get the 10% late penalty waived?
Yes, for reasonable cause under §6592. File CDTFA-735 with documentation; interest under §6591.5 is not waivable.
Do I sign electronically on the portal?
Yes. Submitting under your own login satisfies the signature requirement of §7152. Save the confirmation as your signed copy.
Can I amend a CDTFA-401-2 after filing?
Yes. File an amended return through the portal or by paper under Regulation 1585. Refund claims must be filed within three years per §6902.
What if I write the wrong district code on Schedule A2?
No filing-rejection happens, but the CDTFA reallocates under Regulation 1802 and bills the correct district. File an amended return to fix the error.
Do partners both sign the return?
No, only one general partner needs to sign under §7152. The signing partner accepts liability for the entire return on behalf of the partnership.
