Payroll has a yearly rhythm: wage limits reset in January, tax forms arrive early in the year, benefit elections affect later checks, and life events can make an old Form W-4 inaccurate. This employee calendar is different from an employer’s federal tax-deposit calendar.
January: verify the reset
Check the first pay stub for salary or hourly rate, filing status, benefit elections, work state, and year-to-date totals reset to zero. Social Security wage-base tracking starts again. Employers generally furnish Form W-2 by the applicable late-January deadline.
February through April: reconcile
Compare Form W-2 with final pay-stub totals and prepare the prior-year return. If a balance due or very large refund reveals a mismatch, use the IRS estimator and submit a new W-4. Filing deadlines can shift for weekends, holidays, or disaster relief, so confirm the official date.
Spring and summer: review changes
Check withholding after a raise, bonus, overtime surge, second job, marriage, divorce, birth, move, or benefit change. Review year-to-date gross, federal withholding, FICA, and state tax rather than extrapolating one unusual check.
Estimated-tax checkpoints
Employees with substantial income that is not subject to withholding may need estimated payments. Applicable quarterly due dates and safe-harbor rules should be confirmed with current IRS guidance. Increasing wage withholding may be another planning option.
Autumn: benefits and year-end planning
Open enrollment can change pre-tax premiums, HSA or FSA elections, and next year’s net pay. Check retirement-contribution progress and applicable annual limits. Consider whether irregular income or credits warrant a W-4 update.
December: save records
Keep the final pay stub, confirm the employer has a current address for tax forms, and document outstanding payroll corrections. Do not rely on a fixed employer deposit calendar without identifying the employer’s assigned deposit schedule and official rules.
Worked paycheck example
A worker who adds a second job in June should not wait until tax filing season to discover underwithholding. A midyear IRS estimator review can use both jobs, year-to-date withholding, remaining pay periods, and expected credits to suggest updated W-4 entries.
Common mistakes to avoid
- Using an old calendar for a movable deadline
- Waiting until December to correct every issue
- Ignoring the first check after open enrollment
- Discarding the final pay stub before receiving Form W-2
- Confusing employee review dates with employer deposit deadlines
