Unfiled payroll tax returns (Form 941 and 940)
Last updated · Reviewed for accuracy against IRS.gov guidance
If a business doesn't file required Forms 941 or 940, the IRS sends delinquency notices such as CP259 and can prepare substitute returns under IRC section 6020(b), assessing tax from wage data. Failure-to-file penalties of 5% a month (up to 25%) build quickly. Filing every missing return is the first step toward any payment plan or relief.

How the IRS finds missing returns
When you get an EIN and report employees, the IRS sets filing requirements for Forms 941 and 940. If they stop arriving, CP259 and similar notices follow — one per form and period. W-2 data from the Social Security Administration also lets the IRS see wages without matching 941s.
Substitute returns under 6020(b)
IRC section 6020(b) allows the IRS to prepare an employment tax return from available information when a business doesn't file. These substitute returns often overstate liability because they don't credit deposits correctly or reflect actual wages. Filing your own original return generally replaces the IRS figures. A revenue officer will usually set a deadline to file before preparing them.
Gathering the information
- Payroll registers and W-2/W-3 copies for each year.
- EFTPS deposit history and bank statements.
- Prior-quarter returns for consistency.
- For missing records, wage and income transcripts from the IRS can help reconstruct totals.
Each quarter needs its own Form 941 — use the version for that year. A payroll professional can reconstruct liability schedules accurately, which matters for deposit penalties.
Penalties for late payroll returns
Failure to file runs 5% per month of the unpaid tax, up to 25%, plus failure-to-pay and interest at 7%. Filing quickly limits the failure-to-file penalty; if the business has no recent penalties, First Time Abate may remove it for one period.
After you file
Expect balances to be assessed and a trust fund investigation if trust fund taxes are unpaid. Then set up a payment plan and keep current deposits going. Take the business assessment and answer "yes" to unfiled returns to see matched options.

Do I need to file 941s for quarters with no wages?
+
Generally yes, unless you filed a final return or are registered as a seasonal employer.
How far back should I file?
+
The IRS generally expects all delinquent employment tax returns; a revenue officer may specify which periods.
Can I file all missing 941s at once?
+
Yes. File each quarter separately, all in one batch if you're catching up.
Will filing trigger a TFRP?
+
Filing reveals unpaid trust fund taxes, but not filing doesn't avoid the TFRP and adds penalties.
What if I disagree with an IRS substitute return?
+
File your own original return with accurate figures for that period.
Do I also need to file missing W-2s?
+
Yes. Forms W-2 and W-3 go to the Social Security Administration, and late or missing ones carry separate information return penalties.
