A year-to-date pay-stub audit should reconcile beginning balances plus every current-period amount to the latest totals for gross earnings, taxable wages, federal and state withholding, Social Security, Medicare, benefits, retirement contributions, leave, repayments, and net deposits. Investigate resets, duplicate deductions, missing codes, or unexplained jumps before year-end payroll closes and Form W-2 is issued.
Payroll workers say many employees never inspect a pay stub, while workers discover months of missing overtime or wrong deductions only after a large variance appears. A cumulative audit catches errors while records are accessible.
Start here: a practical action plan
- Download every stub.
- Roll forward YTD balances.
- Investigate resets.
- Match Forms W-2.
- Losing portal access.
- Ignoring off-cycle checks.
- Forcing different taxable wage bases to match.
Build a roll-forward instead of checking one check
Download every pay stub before portal access changes. Create columns for pay-period dates, pay date, regular and overtime hours, gross earnings, each taxable-wage base, every tax, benefit, retirement line, reimbursement, repayment, leave balance, and net deposit.
Roll forward the balances. Prior year-to-date plus the current amount should equal the new year-to-date figure unless payroll documents a correction or system change. A new job, new employing entity, or corrected payroll can legitimately start another record, but it should not disappear from the annual reconciliation.
Worked example: find a year-to-date reset
Example: the previous stub shows $48,200 year-to-date gross and the current period shows $3,100. Expected new year-to-date gross is $51,300. The current stub instead shows $3,100.
The apparent reset is $51,300 - $3,100 = $48,200. Ask whether the employer changed legal entities, payroll systems, or employee records and how Forms W-2 will preserve the earlier wages.
| Hypothetical year-to-date roll-forward | Calculation | Amount |
|---|---|---|
| Prior YTD gross | Previous stub | $48,200 |
| Current gross | Current stub | $3,100 |
| Expected new YTD | $48,200 + $3,100 | $51,300 |
| Displayed new YTD | Current stub | $3,100 |
| Apparent missing history | $51,300 - $3,100 | $48,200 |
Audit earnings, taxes, benefits, and cash together
Compare gross earnings with federal taxable wages, Social Security wages, and Medicare wages. Pretax retirement, health, HSA, FSA, and other benefits can affect these bases differently. Ask for plan-specific treatment rather than forcing them to match.
Tie net pay to actual bank deposits. A correct stub with a missing or reversed deposit is a banking or delivery problem, while an incorrect stub requires a payroll correction. Track off-cycle checks and voids.
Close the year with a correction log
Review contribution caps, deductions that should have ended, employer matches, leave balances, garnishment balances, overpayment recovery, and taxable benefits. A wrong current line can compound over many checks.
Before the final payroll cutoff, send payroll a numbered discrepancy list with evidence and requested outcomes. Reconcile the final stub to every Form W-2 and W-2c, then preserve the file with the tax return.

Frequently asked questions
Which year-to-date totals should I check?
Check earnings, taxable wage bases, taxes, benefits, retirement, leave, repayments, and net pay.
Why can federal taxable wages differ from Social Security wages?
Different pretax benefits and statutory rules can affect the wage bases differently.
Does a YTD reset always mean lost wages?
No. It can reflect a new entity or payroll record, but annual forms must still report the proper amounts.
How do I handle an off-cycle check?
Add it as its own row and confirm it enters the correct year-to-date totals and bank deposits.
When should I run the audit?
Review every pay period and perform a full reconciliation before the final payroll cutoff and again after Form W-2 arrives.
What if the portal will close after I leave?
Download stubs, tax forms, benefit records, leave history, and payroll messages before access ends.
