How to Complete the 2026 Form 941 Line by Line
Complete Form 941 in order, Part 1 lines 1 to 15, Part 2 line 16, then Parts 3 to 5, on the Form 941 for 2026 (Rev. March 2026). The inputs to those lines come from records you can pull before you start, including the pay-period headcount, quarterly wage totals, deposit confirmations, and a liability record that must equal line 12.
Which Form 941 revision applies in 2026?
The 2026 form is the March 2026 revision, labeled “(Rev. March 2026)” under “Form 941 for 2026” and “Form 941 (Rev. 3-2026)” at the foot of each page (Form 941). The Instructions for Form 941 (Rev. 03/2026) say to use the March 2026 revision for quarter one, to expect it for quarters two to four, and to use no earlier revision for 2026. Schedule B (Form 941) is still the Rev. March 2024 form, as of October 2026.
As of October 2026, the changes in the instructions include the $184,500 social security wage base, a new Aggregate Return Filers Only section, direct deposit of refunds, and electronic balance-due payments. Qualified tips and qualified overtime are withholding and information-return changes with no new Form 941 line, and both remain generally subject to social security and Medicare tax.
Complete lines 1 to 11 from your payroll records
What you need first.
* Export quarterly wage totals by tax base, with 401(k) deferrals separate.
* Gather tip reports and adjustment records.
1. Enter on line 1 the number of employees paid for the pay period that includes March 12, June 12, September 12, or December 12, whichever matches the quarter. Leave out household and farm employees, employees in nonpay status, pensioners, and active military (Instructions for Form 941 (Rev. 03/2026)).
2. Enter wages, tips, and other compensation on line 2, using the amounts that would also appear in W-2 box 1, which excludes elective deferrals such as 401(k) (General Instructions for Forms W-2 and W-3 (2026)). Enter income tax withheld on line 3. Check line 4 only if no line 2 wages are subject to social security or Medicare tax.
3. Enter social security wages figured before payroll deductions on line 5a, times 0.124 (6.2% each for employer and employee), until an employee reaches $184,500, as of October 2026. Enter tips reported to you on line 5b, also times 0.124. Enter Medicare wages and tips times 0.029 on line 5c, which has no limit. Enter wages and tips subject to Additional Medicare Tax times 0.009 on line 5d, which applies to the employee only once wages pass $200,000. Line 5e adds column 2.
4. Line 5f is tax due under a Section 3121(q) Notice and Demand. Add lines 3, 5e, and 5f on line 6. Lines 7 to 9 adjust for fractions of cents, third-party sick pay, and uncollected employee social security and Medicare tax on tips and group-term life premiums for former employees. Line 10 combines lines 6 to 9, and errors from earlier quarters belong on Form 941-X.
5. Enter on line 11 the qualified small business payroll tax credit for increasing research activities, from Form 8974 line 12 or 17, attached.
Test each pay item separately for income tax withholding, social security and Medicare, and federal unemployment (FUTA) tax (Publication 15 (2026)). Employee 401(k) deferrals are generally exempt from income tax withholding but taxable for social security, Medicare, and FUTA. W-2 box 3 includes them and box 1 does not, so line 5a can exceed line 2, and leaving them off lines 5a and 5c understates those lines. Employer qualified-plan contributions and employer health savings account (HSA) contributions are exempt from all three when excludable from the employee’s income, but payroll-deduction HSA contributions outside a cafeteria plan are wages.
Hypothetical. One employee is paid $20,000 in the quarter with a $2,000 elective 401(k) deferral, no tips, and $2,150 of income tax withheld. Line 2 is $18,000 because the deferral is excluded from the box 1 basis. Line 3 is $2,150. Line 5a is $20,000, and $20,000 times 0.124 is $2,480. Line 5c is $20,000, and $20,000 times 0.029 is $580. Line 5e is $3,060. Line 6 is $2,150 plus $3,060, which is $5,210. With no adjustments or credit, lines 10 and 12 are $5,210.
Reconcile lines 12 to 15 against your deposits
Line 12 is the figure the lookback and the $2,500 test use (Publication 15 (2026); Instructions for Form 941 (Rev. 03/2026)).
What you need first.
* Gather the quarter’s deposit confirmations.
* Find any overpayment credits applied from earlier periods.
1. Subtract line 11 from line 10 to get line 12.
2. Enter total deposits on line 13, including overpayments applied from a prior quarter or from Form 941-X or 944-X filed in the current quarter.
3. Subtract line 13 from line 12 to get a balance due on line 14. No payment is due under $1.
4. Enter an overpayment on line 15a, then check one box on line 15b to apply it to the next return or take a refund by direct deposit on lines 15c to 15e, otherwise the IRS generally applies it to the next return.
The line 14 instructions set the payment method by whether you were required to deposit. A check or money order goes with Form 941-V, and electronic funds transfer (EFT) or card payments use no voucher.
What a correct result looks like. Line 13 matches deposits you hold confirmations for, and any difference from line 12 shows on line 14 or line 15a.
Line 16 and Schedule B, the liability record deposits are tested against
Line 16 and Schedule B report liability by the date wages were paid, not by deposit date, and each total must equal line 12.
The lookback rule, not pay frequency, sets the deposit schedule before each calendar year (Publication 15 (2026)). For 2026 the lookback period is July 1, 2024 through June 30, 2025 (calendar year 2024 for 2024 or 2025 Form 944 filers), measured on line 12, with $50,000 or less monthly and more than $50,000 semiweekly, as of October 2026. Only the $100,000 rule moves a monthly depositor mid-year, to semiweekly the next day for at least the rest of that year and the following year.
What you need first.
* Export the quarter’s liability by wage-payment date.
* Note any day this quarter when $100,000 or more in tax accumulated.
1. Check the first box on line 16 if line 12 is under $2,500 this quarter or last quarter and no $100,000 next-day obligation arose this quarter, then go to Part 3. If last quarter was under $2,500 but line 12 is $100,000 or more, give a liability record.
2. Check the second box if you were a monthly depositor for the whole quarter, and enter each month’s liability by the dates wages were paid, totaling line 12.
3. Check the third box if you were a semiweekly depositor for any part of the quarter, and attach Schedule B (Form 941). An employer that became semiweekly mid-quarter files it for the whole quarter.
4. List liability on Schedule B, the Report of Tax Liability for Semiweekly Schedule Depositors, by the date wages were paid, totaling line 12. The IRS uses it with EFT data to test timeliness (Instructions for Schedule B (Form 941)). It can be skipped when line 12 is under $2,500.
5. If the line 16 or Schedule B total does not equal line 12, deposits may not be counted as timely, and a semiweekly depositor that omits Schedule B may be assessed an “averaged” failure-to-deposit penalty (Instructions for Form 941).

Complete Parts 3 to 5 and file by the due date
Parts 3 to 5 cover final-return and seasonal status, a designee, and the signature (Instructions for Form 941).
What you need first.
* Identify who signs for your entity type.
* Locate the final wage date if this is a final return.
1. Check line 17 on a final return, enter the final wage date, and attach a statement naming who keeps the payroll records and where.
2. Check line 18 on every Form 941 a seasonal employer files, because otherwise the IRS expects a return for every quarter.
3. In Part 4, check Yes to let a named person discuss the return with the IRS, and enter that person’s name, phone number, and five-digit PIN. Then complete both pages of Form 941 and sign in Part 5. The owner signs for a sole proprietorship, a duly authorized principal officer for a corporation, and a responsible and duly authorized partner, member, or officer for a partnership. The quarter marked on Schedule B must match the return.
4. File by the last day of the month after quarter end, or by day 10 of the second month after quarter end if all taxes were deposited on time in full (Instructions for Form 941). As of October 2026, the third quarter of 2026 is due Monday, November 2, 2026, or Tuesday, November 10, 2026, and the fourth quarter is due Monday, February 1, 2027, or Wednesday, February 10, 2027.
Frequently Asked Questions
What wages are included in Form 941?
Wages, bonuses, and tips are included to the extent each is subject to income tax withholding, social security, or Medicare tax, and a payment can be exempt from one and taxable under another. Employee 401(k) deferrals are generally exempt from income tax withholding but taxable for social security and Medicare (Publication 15 (2026)).
What wages are not reported on Form 941?
Payments exempt from all of income tax withholding, social security, and Medicare are not reported, such as employer qualified-plan contributions, employer HSA contributions, and a deceased worker’s wages paid after the year of death. Family-member wages for work in the employer’s business are not exempt from all three, since income tax withholding generally applies (Publication 15 (2026)).
What type of depositor must file Schedule B with Form 941?
Semiweekly depositors must file Schedule B unless line 12 is under $2,500, and monthly depositors do not file it. An employer is semiweekly if it reported more than $50,000 in the lookback period or accumulated $100,000 or more on any day in the current or prior calendar year (Instructions for Schedule B (Form 941)).
What are five places a Form 941 can go wrong?
Five places are an earlier revision for 2026, 401(k) deferrals left off lines 5a and 5c, a line 16 or Schedule B total that differs from line 12, a missing Schedule B from a semiweekly depositor, and quarterly totals that differ from Form W-3 for withholding, social security, and Medicare, which may bring IRS contact (Instructions for Form 941; Publication 15 (2026)).
Is there a new Form 941 for 2026?
Form 941 for 2026 (Rev. March 2026) is the current version, and as of October 2026 the IRS expects employers to use it for all four 2026 quarters (Instructions for Form 941).
Do I have to e-file Form 941?
Not for an ordinary employer, since the IRS employment tax due dates page says Form 941 may be filed on paper or through e-file. The Instructions for Form 941 encourage e-filing, and certified professional employer organizations (CPEOs) must generally e-file Form 941 with Schedule R.
