2026 Paycheck Tax Checklist =========================== A practical 20-minute review of your paycheck, withholding, and pre-tax benefits for the 2026 tax year. 1. Confirm the inputs --------------------- Start with the numbers your employer actually uses. A small input mistake changes every line below it. [ ] Use gross pay, not take-home pay The calculator starts from annual gross wages before taxes and deductions. If you know your hourly rate, use the hourly mode instead of guessing an annual salary. Link: /paycheck-calculator [ ] Pick the right filing status Single, married filing jointly, married filing separately, and head of household have different brackets and standard deductions. Use the status you expect on your 2026 return. [ ] Check your pay frequency Biweekly is 26 checks per year, semimonthly is 24, and weekly is 52. Confusing biweekly with semimonthly creates a visible error in per-check estimates. [ ] Add pre-tax contributions Enter your traditional 401(k) percentage and annual pre-tax health or HSA contributions. These reduce taxable income, and Section 125 health contributions usually reduce FICA too. 2. Review federal withholding ----------------------------- Federal income tax is usually the largest line on a paycheck. Check it once after a raise, a job change, or a filing-status change. [ ] Revisit your W-4 A new job, marriage, divorce, or side income can make an old W-4 inaccurate. Submit a new form to your employer rather than waiting for a surprise at tax time. [ ] Compare withholding with your estimate Use the calculator's federal income tax line as a planning benchmark. Payroll tables and your W-4 can still produce a different amount. Link: /paycheck-calculator [ ] Check the Social Security wage base In 2026, Social Security is 6.2% on wages up to $184,500. If you change jobs mid-year, watch for over-withholding and claim the excess on your return. [ ] Watch Additional Medicare Medicare is 1.45% of wages, plus 0.9% above $200,000 for single filers and $250,000 for married filing jointly. Employers withhold the extra amount once wages cross the threshold. 3. Review state and local withholding ------------------------------------- State rules vary widely, and local taxes are the most commonly missed line item when people compare offers. [ ] Confirm your work state and residence state If you live in one state and work in another, reciprocity rules and convenience-of-the-employer rules decide which state taxes your wages. Ask payroll which state is withholding. [ ] Check whether your state taxes wages Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington (wages), and Wyoming do not tax wage income. Other states use flat or graduated rates. Link: /compare [ ] Look for a local income tax New York City, Yonkers, Philadelphia, Detroit, Kansas City, St. Louis, Portland, and many Ohio and Indiana localities levy their own tax. The calculator excludes these unless noted on the state page. [ ] Check state withholding after a move Update your address and state withholding form with payroll as soon as you move. Partial-year residents often need to file in both states. 4. Check pre-tax benefits and deductions ---------------------------------------- Pre-tax benefits can lower your tax bill, but they also reduce the cash that reaches your bank account today. Make the trade-off on purpose. [ ] Capture the full 401(k) match An employer match is part of your compensation. Check the vesting schedule and contribute at least enough to receive the full match if your budget allows it. [ ] Review HSA and FSA elections HSA contributions reduce income tax and, through payroll, FICA. FSA elections are usually use-it-or-lose-it, so compare the balance with expected medical costs. [ ] Check health premium treatment Premiums under a Section 125 cafeteria plan typically reduce federal income tax, state income tax, Social Security, and Medicare. Premiums paid outside that plan may not. [ ] List post-tax deductions separately Union dues, garnishments, charitable contributions, and some insurance premiums come out after tax. They lower your net pay but not your taxable wages. 5. Audit one full pay stub -------------------------- Pick a normal paycheck and reconcile it line by line. This catches most payroll errors before they repeat all year. [ ] Match gross pay to your offer or timesheet Multiply your rate by regular hours, then add overtime, bonus, commission, and paid leave. Compare that total with the gross pay line. [ ] Confirm each tax line You should see federal income tax, Social Security, Medicare, and state income tax where applicable. A missing or duplicated line is worth a payroll ticket. [ ] Reconcile year-to-date totals Year-to-date gross, taxes, and 401(k) should equal the prior stub plus the current period. A mismatch can signal a payroll system issue. 6. Plan for year-end and job moves ---------------------------------- A few checks now can prevent a cash-flow surprise in April or when you change jobs. [ ] Estimate tax on side income Freelance, contract, and gig income usually has no withholding. Set aside money now or make quarterly estimated payments to avoid an underpayment penalty. [ ] Keep your W-2 and 1099 documents together Store 2026 tax documents in one folder as they arrive. If you move, make sure your employer and any clients have your current address. [ ] Compare an offer on take-home pay, not salary alone The same gross salary can produce thousands of dollars of difference after state tax. Compare the two states at your actual salary before accepting an offer. Link: /compare [ ] Add cost of living and local taxes Income tax is only one part of a move. Property tax, sales tax, rent, commuting costs, and local payroll taxes can outweigh a lower state income tax rate. Last reviewed: 2026-02-11 Estimates for planning only. Not tax advice.
