Schedule B (Form 941) (2024) Report of Tax Liability for Semiweekly Schedule Depositors
Purpose and Requirements
Schedule B (Form 941) 2024 documents daily tax liability for employers on semiweekly deposit schedules. Employers must complete and attach this schedule to Form 941 if they reported more than $50,000 of employment taxes in the lookback period or accumulated a tax liability of $100,000 or more on any given day in the current or prior calendar year. The total liability on the final line of Schedule B must match Form 941 line 12 without adjustment for prior-year Forms 941-X corrections.
The current form carries a March 2024 revision date and accompanies the Instructions for Schedule B (Form 941) revised in June 2025. These instructions clarify that employers cannot reduce current quarter tax liability by adjustments reported on any Form 941-X or Form 944-X filed for prior periods. Schedule B reflects gross liability for the current quarter only and serves as a detailed support document for Form 941 line 12 reconciliation during IRS audits.
Filing Steps and Procedures
Step 1: Verify Semiweekly Depositor Status
You must determine whether semiweekly depositor status applies before filing Schedule B. You become a semiweekly depositor if you reported more than $50,000 of employment taxes during the lookback period. You also become a semiweekly depositor if your accumulated employment tax liability reaches $100,000 or more on any single day in the current or prior calendar year, regardless of your normal deposit schedule.
Step 2: Select the Correct Quarter Box
Mark the appropriate quarter box (1, 2, 3, or 4) corresponding to the calendar quarter you are reporting. This selection must align with the quarter reported on your Form 941.
Step 3: Enter Your Employer Identification Number
Record your employer identification number at the top of Schedule B. Confirm the EIN matches your Form 941 and all employment tax records for the quarter.
Step 4: Record Daily Tax Liability
Enter your tax liability in the numbered spaces (1–31) for each day of the month wages were paid. You must use Section 11 in Publication 15 (Circular E), Employer's Tax Guide, to calculate daily liability. Daily amounts must reflect combined federal income tax withheld, employee and employer Social Security tax, and employee and employer Medicare tax.
Step 5: Complete Month 1 Entries and Subtotal
Sum all daily entries for the first month of the quarter and enter this subtotal on the designated line for the month 1 tax liability.
Step 6: Complete Month 2 Entries and Subtotal
Repeat the daily entry and subtotal process for Month 2 of the quarter. Record all wage payment dates and corresponding tax liabilities in the second section of the form.
Step 7: Complete Month 3 Entries and Subtotal
Record all daily entries for the third month of the quarter. Calculate the Month 3 subtotal and ensure all three months of the selected quarter are reported consistently.
Step 8: Calculate Total Quarterly Liability
Add the subtotals for Month 1, Month 2, and Month 3 to determine the total liability for the quarter, which must equal line 12 of Form 941 without modification or reduction for any Forms 941-X filed in prior years.
Step 9: Verify Matching Totals
Compare the quarterly total on Schedule B to Form 941 line 12 before submitting your return, and you must correct any discrepancy on Form 941 first, rather than altering Schedule B to force a match.
Step 10: Attach Schedule B to Form 941
Attach Schedule B to Form 941 as a required supporting document. You cannot file Schedule B separately from Form 941.

Key Regulatory Updates for 2024
The following regulatory clarifications apply to Schedule B for the 2024 tax year:
- The March 2024 revision of Schedule B emphasizes that prior-year adjustments reported on Forms 941-X or 944-X must not reduce the tax liability reported on Schedule B for the current quarter.
- The $100,000 accumulated liability threshold triggering semiweekly status applies to any day in the current or prior calendar year and remains unchanged for 2024.
- Employers who accumulate $100,000 or more in tax liability on any day become semiweekly depositors beginning the next business day and must complete Schedule B for the entire quarter.
- Publication 15 (2024 edition) remains the authoritative source for daily tax liability calculation methodology under Section 11.
- Employers must reference the current year's Publication 15 Section 11, not prior editions, when calculating deposit schedules and daily liability amounts.
Deposit Schedule Determination
You determine your deposit schedule based on the total taxes reported during the lookback period. The lookback period for Form 941 filers covers the 12 months from July 1 two years ago through June 30 of the prior year. Employers reporting $50,000 or less during this period follow a monthly deposit schedule unless they trigger the $100,000 next-day deposit rule.
Employers reporting more than $50,000 during the lookback period become semiweekly depositors for the entire calendar year. New employers without a lookback period history are monthly depositors unless they accumulate $100,000 or more on any single day. The $100,000 threshold is determined before you consider any reduction of liability for nonrefundable credits and immediately changes your deposit schedule regardless of your prior status.
Schedule B Compliance and Record Alignment
Schedule B serves exclusively as a detailed support document for Form 941 line 12 reconciliation. The schedule does not replace deposit records or payment documentation, but must align with them for audit purposes. The IRS uses Schedule B to determine if you deposited federal employment tax liabilities on time and may propose an averaged failure-to-deposit penalty if you fail to complete and file Schedule B as a semiweekly depositor properly.
You must maintain accurate daily liability records that correspond to the dates wages were paid, not the dates payroll liabilities were accrued, or deposits were made. You cannot use Schedule B to show federal tax deposits because the IRS receives deposit data from electronic funds transfers through the Electronic Federal Tax Payment System.
