How to Run Year-End Payroll and File W-2s
Year-end payroll is where twelve months of pay runs get reconciled into one accurate set of W-2s. Do the reconciliation early and January is calm; leave it and every small error surfaces at the worst time.
What year-end payroll involves
Closing payroll for the year means reconciling total wages and withheld taxes against your remittances, verifying every employee’s legal name, address, and tax ID, accounting for special items like fringe benefits and multi-state wages, and then generating and filing accurate W-2s with the SSA and each employee. Multi-state wages and equity compensation are the two areas that most often need attention.
- Reconcile year-to-date wages and taxes to your remittances
- Verify employee legal names, addresses, and Social Security numbers
- Account for fringe benefits, imputed income, and equity comp
- Allocate wages correctly for multi-state employees
- Generate, distribute, and file W-2s by the deadline
The year-end checklist
Before you file W-2s
- Final payroll of the year processed and posted
- Quarterly filings reconciled against year-to-date totals
- Employee data verified - no missing or mismatched SSNs
- Fringe benefits and imputed income captured
- Multi-state wage allocations reviewed
- W-2s reviewed for accuracy before transmission

How Fintra runs year-end payroll
Fintra’s multi-state payroll reconciles wages and taxes throughout the year, so year-end is a verification rather than a rebuild. It tracks per-state wage allocation for employees who move, folds in equity-related income, and generates and files W-2s with the SSA and employees. Because payroll, HRIS, and equity share one record, the numbers on the W-2 already tie out.
- Continuous wage and tax reconciliation, not a year-end rebuild
- Per-state wage allocation for employees who relocate
- Equity-related income folded into year-end wages
- W-2 generation and filing with the SSA and employees
Frequently asked questions
When are W-2s due?
W-2s are generally due to employees and to the Social Security Administration in late January. Reconciling wages and verifying employee data through the year is what keeps that late-January deadline manageable.
How do multi-state wages affect W-2s?
Employees who work in or relocate between states need their wages and withholding allocated to each state correctly. Getting this wrong misstates state income on the W-2 and often forces a corrected filing, so review allocations before transmitting.
What should year-end payroll reconciliation cover?
Total wages and withheld taxes reconciled to your remittances and quarterly filings, verified employee identity data, captured fringe benefits and imputed income, and reviewed multi-state allocations - all before W-2s are generated.
How does equity compensation show up at year-end?
Income from events like NSO exercises and RSU settlements is generally taxable wages that must appear on the W-2. Folding equity income into year-end payroll ensures wages and withholding are complete and accurate.
