Form 941 Schedule B - 2025 Filing Requirements
& Instructions

Who must file Schedule B?

Form 941 Schedule B is filed by semiweekly depositors. Generally, you are considered a semiweekly depositor if:

• You reported $50,000 or more of employment taxes during the lookback
  period or
• You incurred a $100,000 or more tax liability on any single day in the current or prior
  calendar year.

How to fill out 941 Schedule B?

Here are the step-by-step instructions to fill out Form 941 Schedule B:

1. Enter employer information: This includes your EIN, business name, and address.
2. Choose quarter: Select the quarter for which you are filing Form 941.
3. Enter tax liability breakdown: Enter your daily tax liability on the appropriate dates when wages were paid.
4. Calculate total liability: This is the sum of your monthly tax liabilities. The total must equal
   line 12 on Form 941.
5. Adjust tax liability for the qualified small business payroll tax credit for increasing research activities (Form 941, line 11): This is required if you attach Form 8974 in line 11 of Form 941.

When is the 941 Schedule B due?

Form 941 Schedule B is due each quarter along with Form 941. For the 2025 tax year, the quarterly deadlines are as follows:

• Q1 (January–March): Due April 30, 2025
• Q2 (April–June): Due July 31, 2025

While Schedule B reports your daily tax liability, your deposit due dates may differ based on your deposit schedule. Learn more about IRS deposit requirements.

What happens if you fail to file 941 Schedule B?

Schedule B is used by the IRS to determine whether you’ve deposited your employment tax liabilities on the correct dates. If you fail to file Schedule B—or if it’s incomplete, inaccurate, or late—the IRS may:

• Estimate your liability using an "averaged" method, which spreads your total quarterly tax evenly across all days in the quarter.
• Assess a Failure-to-Deposit (FTD) penalty, especially if your deposits do not align with actual liability dates.

Penalties can apply if:

• You don’t deposit taxes on time
• Your deposits are less than the required amount
• You omit or misreport dates on Schedule B

How to correct errors on Form 941 Schedule B?

If you filed a Schedule B with incorrect liability dates or amounts, the method for correcting it depends on whether your total tax liability changes.

• If the total liability does not change

  You may submit a corrected Schedule B on its own:

  • Write “Amended” at the top of the new Schedule B.
  • Send it to the address listed in your FTD penalty notice, if applicable.
  • There’s no need to file Form 941-X if the correction does not impact your total tax liability.

  Example: You originally reported a $5,000 liability on the wrong day. Since the total is still $5,000, you can simply correct the liability date using an amended Schedule B.

• If the total liability changes

  You must file:

  • Form 941-X to report the corrected liability.
  • A revised Schedule B showing the corrected daily breakdown.

  If you're correcting a decrease, ensure the total liability on Schedule B matches Form 941-X.

  If you're correcting an increase, and you were assessed an FTD penalty, you must file an amended Schedule B even if you’re submitting 941-X on time.
