A year end payroll forms checklist lists each form a client's payroll must produce, usually W-2s, the W-3 transmittal, the fourth-quarter Form 941 and the annual Form 940, plus state forms. It then lists the totals to agree first: payroll register to general ledger, and tax deposits to the bank statements. Filing comes only after both agree.
Which forms go on a year end payroll forms checklist?
A year end payroll forms checklist starts with the federal forms every employer files and adds the state forms for each state where the client has employees. For most small clients, the federal list is short: a W-2 for each employee, one W-3, the last quarterly Form 941 and the annual Form 940 for federal unemployment tax.
Dates come from the forms' own instructions, which the IRS updates each year. The General Instructions for Forms W-2 and W-3 set February 1, 2027 as the date for filing Copy A of 2026 W-2s and the W-3 with the Social Security Administration, and the same date for giving employees their copies. The W-3 is the transmittal that accompanies Copy A. An employer filing at least 10 information returns in total, counting W-2s and the 1099 series together, generally has to file electronically.
The Instructions for Form 940 give that form's due date each year and allow ten more days when all federal unemployment tax was deposited on time. Check the current year's version rather than last year's date.
The checklist in order:
- Confirm the employee list, addresses and taxpayer numbers.
- Agree the payroll register to the books.
- Trace every tax deposit to the bank statements.
- Review the draft W-2s, including box 12 codes.
- File the W-2s and W-3, and give employees their copies.
- File the fourth-quarter 941 and the annual 940.
- File the state wage and unemployment forms.
- Save copies with the year's records.
The W-2 instructions say to keep Copy A and the W-3 for at least four years.
Payroll register totals agreed to the books before W-2s
The payroll register is the payroll provider's record of every paycheck, and its annual totals must agree to the general ledger before any W-2 is filed. Gross wages, employer taxes, withholdings and benefits each have a ledger account, and each should match the register to the cent or have a written reason why not.
Here is an example agreement for a small client. The figures are made up.
| Total | Payroll register | General ledger | Difference |
|---|---|---|---|
| Gross wages | 312,480.00 | 312,480.00 | 0.00 |
| Employer social security and Medicare | 23,904.72 | 23,904.72 | 0.00 |
| Federal unemployment tax | 840.00 | 840.00 | 0.00 |
| Employee 401(k) deferrals | 14,600.00 | 13,400.00 | 1,200.00 |
| Health premiums withheld | 7,800.00 | 7,800.00 | 0.00 |
The 1,200.00 gap in deferrals is the kind of difference that matters. It usually means one withholding sent to the retirement plan provider was coded to the wrong account, or was never sent. Retirement deferrals are reported on W-2s with a box 12 code, and the W-3 instructions note that box 12a on the W-3 totals only certain codes, including D through H. Getting the deferrals right in the books is covered in retirement contributions in client books.
Payroll tax deposits traced to the bank statements
Payroll tax deposits are the employer's payments of withheld and employer taxes to the IRS and the state. Each deposit the payroll provider reports should appear as a line on the client's bank statement, on or near the reported date and for the same amount. Tracing them proves the returns match what actually left the bank.
Work deposit by deposit for the fourth quarter at minimum, and for the whole year if the client changed payroll providers. Look for a line naming the IRS or the state tax agency for each deposit, then mark it as matched. A deposit the provider reports but the bank never shows means the provider did not pull the money, or pulled it from a different account.
This step is faster when statements are already converted and coded. With AutoBankConvert, each client's bank lines land in their own workspace with payroll tax debits already sorted by the client's rules, so the trace is a comparison of two short lists.
What if a year end payroll total does not match?
A year end payroll total that does not match usually traces to a manual check outside the payroll system, a ledger-only correction, a miscoded deposit, or a paycheck dated in one year but posted in another. Find the cause before filing, because changing a W-2 later means a corrected form.
The W-3 instructions say amounts on Forms W-2, 941 and related returns should agree with the W-3, and that differences can lead to contact from the IRS or SSA. They also advise keeping the reconciliation for future reference.
Common sources to check first:
- Manual checks. A final paycheck written by hand that never reached the payroll register.
- Year boundary. A pay period ending December 31 and paid January 2 counts in the year it was paid.
- Bonuses paid through accounts payable. A bonus paid as a vendor check is still wages.
- Fringe benefits. Personal use of a company vehicle or other taxable benefits may need adding to wages.
If a form was already filed with a wrong figure, the fix is a correction, and the books may need a note too. Books changed after taxes were filed covers handling the ledger side.
Year end payroll forms for people paid outside payroll
Some people who worked for a client never appear in the payroll register: an owner who took draws, a family member paid by app, a worker paid by check or transfer. The year end payroll forms checklist should ask about each, because the register cannot show what it never recorded.
Three cases to settle before filing:
- The owner. A sole proprietor's draws are not wages and get no W-2. An S corporation owner who works in the business is usually an employee, and pay taken as transfers instead of payroll is a problem for the preparer to hear about now.
- People paid by Zelle or Venmo. App transfers to a worker may be wages or contractor payments. Sort them by asking who each payee is; the section on Zelle and Venmo payments to workers and tax authorities covers how.
- Late hires and departures. An employee hired in December or let go in January still needs a W-2 for the year they were paid.
Each of these is a question for the client, asked in writing before the forms go out. A filtered list of transfers from converted statements in AutoBankConvert makes the question specific: names, dates and amounts.
