Why your pay stub matters

A pay stub is more than a receipt — it’s a record you’ll use for tax filing, budgeting, benefits checks, and resolving payroll errors. Employers must provide accurate wage statements; reviewing yours every pay period helps catch mistakes early and avoid surprises at tax time. In my practice helping clients with paychecks and budgeting, I’ve seen small errors compound into large problems if left unreported.

Quick tour: the terms you’ll see and what they mean

Below are the most common pay stub fields and how to read them. I describe what to look for and practical steps you can take if something looks wrong.

  • Gross pay

  • What it is: Total earnings before any deductions for the pay period. It includes regular pay, overtime, bonuses, commissions, and taxable fringe benefits.

  • How to check it: Multiply hours worked by hourly rate (or confirm salary pro‑rata). For salaried workers, confirm the pay period portion of the annual salary matches what your employer agreed.

  • Net pay (take-home pay)

  • What it is: The amount deposited to you after all withholdings and deductions.

  • Why it matters: The figure to use when building your budget and reconciling bank deposits.

  • Taxes withheld

  • Federal income tax withholding: Amount your employer withholds based on your Form W-4 and IRS withholding tables. You can change this by updating your W-4 (see guidance on withholding and W-4 updates) (IRS — federal withholding rules).

  • Social Security and Medicare (FICA): Payroll taxes split between Social Security and Medicare. Social Security tax is a fixed percentage applied up to the annual wage base; Medicare is applied on wages and, for high earners, additional Medicare tax rules may apply (see IRS for current rates and thresholds).

  • State/local taxes: Not all states have income tax; regional or city taxes may also be withheld.

  • Pre‑tax and post‑tax deductions

  • Pre‑tax: Deductions that lower taxable income (for example, traditional 401(k) contributions, health insurance premiums for employer plans, and certain flexible spending accounts). These reduce federal and often state tax withholding.

  • Post‑tax: Deductions taken after taxes (for example, Roth retirement contributions, some voluntary benefits, or wage garnishments).

  • Retirement contributions and employer match

  • What to check: Confirm elective deferrals (employee contributions) and any employer match. Employer match typically appears separately as a non‑cash employer contribution or in benefits summaries.

  • Year-to-date (YTD) totals

  • What it is: Cumulative totals for earnings and deductions from the start of the calendar year to the current pay date. Use YTD to reconcile with your W-2 at year end.

  • How to use it: If your YTD Social Security or Medicare withholding seems off, compare with pay history and contact payroll.

  • Paid time off (PTO) and accruals

  • What to check: Some pay stubs show PTO balances and accrual rates. Confirm hours used and remaining balances match your records.

  • Other entries to watch for

  • Garnishments and levies: Court-ordered or agency collections that reduce your net pay. Employers must follow legal notices for garnishments.

  • Reimbursements or expense reimbursements: These may be taxable or non‑taxable depending on the policy and documentation.

  • Fringe benefits or imputed income: Employer paid benefits (like life insurance over certain amounts) may create taxable imputed income shown on the stub.

How to verify accuracy step-by-step

  1. Confirm the pay period dates and hours worked. Small errors here are common — for hourly workers, verify standard hours, overtime hours, and any premium rates.
  2. Recalculate gross pay: hours × rate + overtime + bonuses. For salaried employees, confirm the prorated salary matches the pay schedule.
  3. Check tax withholding: Confirm the federal withholding amount aligns with your W-4 choices. If you’ve recently updated your W-4, ensure payroll processed the change.
  4. Review benefit deductions: Identify which are pre‑tax vs post‑tax. Pre‑tax items reduce taxable wages on the stub.
  5. Compare YTD totals to your last few pay stubs to spot unexpected jumps or missing entries.
  6. If there’s a deduction you don’t recognize, ask payroll for documentation (plan names, deduction codes, or account numbers).

Common causes of surprises and how to fix them

  • Misapplied W-4: If federal withholding is too high or low after submitting a change, contact payroll and refile a corrected W-4. For details on withholding and employer responsibilities, see FinHelp’s guide to federal withholding and Form W-4 options (internal: “Federal Withholding Explained: How Employers Calculate Your Taxes” and “Completing Form W-4: Tips for Accurate Withholding”).

  • Incorrect hours/overtime: Provide time records or clock-in data to HR/payroll and request an audit.

  • Benefits enrollment timing: New hire or open enrollment elections may not take effect immediately. Verify effective dates before assuming deductions should begin.

  • Garnishments or tax levies: These are usually accompanied by formal notices. Ask payroll for the notice and for limits on garnishment amounts.

How pay stubs relate to taxes and end-of-year forms

Your pay stub’s YTD earnings and withholding are the running totals that should match the amounts on your W-2 for the calendar year. Differences can happen if adjustments occur after year-end or if corrections are posted later. Keep pay stubs and employer communications to back up any disputes. The IRS provides official guidance on withholding and payroll tax responsibilities; consult their resources at irs.gov when you need authoritative details.

Special situations to note

  • Multi-state work: Working in multiple states can produce different state withholding entries. If you’ve moved or worked remotely from another state, verify withholding with payroll and consider state reciprocity rules or multi-state filing obligations.
  • Gig, contractor, or 1099 pay: Independent contractors do not receive pay stubs in the same way and are responsible for estimated tax payments and self‑employment tax.
  • Exempt employees: Salary basis and exempt status influence overtime and pay stub reporting — if you’re classified incorrectly, raise the issue with HR or consult the Department of Labor (DOL) guidance.

Practical tips to make pay stubs useful

  • Save digital copies each pay period and back them up. They are evidence in disputes and useful for loan applications.
  • Reconcile three times a year. Match your pay stubs to bank deposits and check YTD totals midway through the year and before year end.
  • Use the pay stub to inform your budget. Track net pay trends to avoid cash shortfalls — for workers with variable pay, see our budgeting strategies for variable paychecks (internal: “Budgeting with Variable Paychecks: A Paycheck-First Method”).
  • Ask for a payroll audit if you spot recurring issues. Many payroll errors are systemic and require a formal review.

When to get outside help

If payroll won’t correct documented errors, or if you suspect tax withholding problems that could cause an unexpected tax bill, consider: contacting the IRS for withholding questions, reaching out to your state labor department for wage and hour concerns, or consulting a tax professional for complex withholding or multi-state issues. For consumer-focused guidance, the Consumer Financial Protection Bureau (CFPB) maintains resources about pay and pay statements.
