To verify a pay stub, run five overlapping checks: inspect the document for visual red flags, audit the math from gross to net, contact the employer directly, cross-reference the net pay against bank deposits and prior tax records, and, where the stakes justify it, pull an electronic income verification. Any single check can miss a well-made forgery. Together they rarely fail, because sustaining the fraud would require the applicant to have forged several independent records at once.
Start With the Document Itself
Before you touch a calculator, look at the stub. Fraudulent ones tend to share features that payroll software almost never produces.
- Perfectly round numbers. Real payroll runs produce figures like $3,847.62, not $3,800.00. If gross pay, taxes, and net pay all land on clean round numbers, the stub was likely typed into a template.
- Inconsistent formatting. Mismatched fonts, uneven column alignment, blurry or pixelated logos, and random spacing changes suggest a word processor rather than a payroll export.
- Spelling and grammar errors. Professional payroll platforms don’t misspell “Medicare” or “Federal.” Typos in field labels are a near-certain sign of fabrication.
- Missing or implausible deductions. A stub showing gross pay and net pay with nothing in between is either fake or reflects an illegal payroll arrangement. A line showing $12 of federal income tax on $5,000 of gross pay fails basic math.
- No employer contact information. Legitimate companies include a phone number, an address, or both. A stub with only a company name is designed to discourage the next verification step.
None of these on its own is conclusive. A small employer might use a template that looks amateurish. Stack two or three together and you have reason to demand more documentation before going further.
While you’re inspecting, confirm the stub carries the identifiers you’d expect: the employer’s legal name, address, and federal Employer Identification Number; the employee’s name and at least the last four of their Social Security number; pay period start and end dates; regular and overtime hours; the pay rate; itemized deductions; and both current-period and year-to-date totals for gross pay, each deduction, and net pay.1Internal Revenue Service. Publication 15 (2026), (Circular E), Employers Tax Guide A stub missing an EIN, deduction line items, or pay period dates deserves extra scrutiny.
Audit the Numbers From Gross to Net
Mathematical verification is where most fakes fall apart, because reconciling every line requires understanding how payroll actually works.
Gross Pay
For an hourly employee, multiply the regular rate by regular hours. If overtime appears, the federal rate is at least one and one-half times the regular rate for hours worked beyond 40 in a workweek.2eCFR. 29 CFR Part 778 – Overtime Compensation Add the two together. The result should match gross pay exactly. For a salaried employee, divide annual salary by the number of pay periods in the year — 26 for biweekly, 24 for semimonthly, 12 for monthly. Any variance beyond a rounding difference is a problem.
Pre-Tax Deductions Come Off First
This is the step most people skip, and skipping it produces false positives. Contributions to a 401(k) or 403(b) and health premiums paid through a cafeteria plan (sometimes labeled “Section 125”) come out of gross pay before taxes are calculated. That means taxable wages are lower than gross pay whenever the employee participates. Miss this and every tax withholding will look slightly too low, and you may flag a legitimate stub as fraudulent.
Tax Withholdings
After pre-tax deductions, check the remaining withholdings against known rates. Social Security tax is 6.2% of taxable wages, but only up to $184,500 in total earnings for 2026. Once year-to-date wages hit that ceiling, Social Security withholding drops to zero for the rest of the year.3Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Medicare tax is 1.45% of all wages with no cap.4Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates An additional 0.9% Medicare surtax kicks in once cumulative wages for the year exceed $200,000, so a high earner’s Medicare withholding will jump partway through the year.5Internal Revenue Service. Topic No. 560, Additional Medicare Tax
Federal income tax withholding is harder to verify to the penny because it depends on W-4 elections, filing status, and any additional withholding the employee requested. You can still check whether it falls in a plausible range. A single filer earning $4,000 biweekly with no special elections should show federal withholding in the hundreds, not $30 and not $1,200. State income tax varies enough that all you can realistically confirm is that it’s present in states that levy it and roughly proportional to gross pay.
Net Pay and Year-to-Date Totals
Subtract every deduction — pre-tax, taxes, and post-tax items like Roth 401(k) contributions or wage garnishments — from gross pay. The result should match the net pay printed on the stub. Then check the year-to-date column: the current period’s gross pay added to the prior YTD balance should equal the new YTD total. Run this check on gross pay, federal tax, and Social Security at minimum. Fabricators often reconcile the current period but forget to update running balances consistently, so YTD is where the forgery shows.
Contact the Employer
A call to the employer’s HR or payroll department is the single most reliable verification step, and the one fraudsters have the hardest time defeating. Look up the company’s phone number independently through its website or a public directory, not the number printed on the stub. A fake stub will sometimes list a personal line where a friend answers pretending to be HR.
Before the employer shares anything, you’ll need a signed authorization from the employee consenting to release of their payroll information. Most companies require this in writing with the employee’s signature, the date, and a clear statement of what you’re requesting. Without it, employers typically decline, and they’re right to do so, because sharing payroll data without consent creates liability for them.
Once you have authorization, ask the employer to confirm the employee’s current status (active, on leave, or terminated), start date, pay frequency, and whether the gross pay figure on the stub is consistent with their records. Some employers will only answer yes or no to each item rather than quote exact figures. That’s enough. If the employer has never heard of the person, you have your answer.
Cross-Reference Bank Statements and Tax Records
A pay stub tells you what the employer says they paid. A bank statement tells you what actually arrived. Pull up the deposit history for the pay date on the stub (or the next business day if it fell on a weekend or holiday) and match the direct deposit against the net pay. The numbers should be identical. Paper checks may post with a small delay, but the amount should still match once cleared.
When you have several pay periods, look for consistency. Legitimate payroll produces deposits of roughly the same amount on a predictable schedule. A biweekly employee should have deposits about every 14 days. Wild swings in amount or irregular timing — say, $2,400 one period and $4,100 the next with no overtime explanation — deserve follow-up.
Prior-year tax documents give you a longer-range check. A W-2 shows total annual wages; divide by the number of pay periods for an average per-period gross. Compare against the current stub. Promotions and raises happen, so a jump isn’t automatically suspicious, but a 60% increase from last year’s W-2 to this month’s stub warrants independent confirmation.
Use Electronic Verification for Higher-Stakes Reviews
Many large employers outsource income verification to The Work Number, a database run by Equifax that pulls earnings data directly from employer payroll feeds. You enter the employer’s unique code and the employee’s Social Security number to generate a report showing pay history, employment dates, and current status. Fees start at roughly $70 per report, though enterprise clients may negotiate lower rates.6The Work Number. Pricing The data comes straight from payroll, so it’s harder to fake than a document the applicant hands you.
Because The Work Number is a consumer reporting agency under federal law, using it triggers Fair Credit Reporting Act obligations. You need a permissible purpose before pulling a report; evaluating someone for a lease, a loan, or employment all qualify. For employment-related reports specifically, you must give the applicant a standalone written disclosure that you intend to obtain a consumer report, and they must authorize it in writing before you request it.7Office of the Law Revision Counsel. 15 U.S.C. 1681b – Permissible Purposes of Consumer Reports Skipping this step exposes you to statutory damages under the FCRA, and applicants do sue.
If you deny an application based on information from one of these reports, send the applicant an adverse action notice. It must identify the consumer reporting agency, state that the agency didn’t make the denial decision, and tell the applicant of their right to obtain a free copy of the report and dispute inaccuracies within 60 days.8Office of the Law Revision Counsel. 15 U.S.C. 1681m – Requirements on Users of Consumer Reports This applies to landlords and lenders equally.
When the Applicant Is Self-Employed
Self-employed applicants and gig workers don’t receive traditional pay stubs, so the five checks above don’t map cleanly onto them. The strongest substitute is an IRS tax transcript through the Income Verification Express Service. The applicant signs Form 4506-C consenting to release, and the IRS faxes the transcript within two to three business days for $4 per transcript.9Internal Revenue Service. Income Verification Express Service for Participants The transcript reflects income actually reported to the IRS, so it’s extremely difficult to falsify.
For gig workers paid through platforms, Form 1099-K reports gross payments from third-party settlement organizations. Platforms must issue a 1099-K when payments exceed $20,000 and transactions exceed 200 in a calendar year.10Internal Revenue Service. Understanding Your Form 1099-K Workers who accept direct credit or debit card payments receive one from the processor regardless of amount. For freelancers paid by individual clients, ask for the 1099-NEC forms they received; each shows what a single client paid during the tax year. Compare the totals against bank deposits for the same period. They won’t match exactly, since deposits include all sources and payments can straddle years, but they should be in the same neighborhood.
If the Stub Turns Out to Be Fake
If the math doesn’t add up, the employer has no record of the person, or the bank deposits don’t match, you’re likely looking at a fabricated document. Don’t confront the applicant with an accusation during verification. Document every discrepancy and the steps you completed, then deny the application on factual grounds. “Unable to verify income” is sufficient language.
For lenders, submitting a fraudulent pay stub to obtain a loan can constitute bank fraud or wire fraud under federal law, both of which carry serious criminal penalties. For landlords, a fake pay stub used to secure a lease is grounds for eviction in every state and may support a civil fraud claim for damages. Reporting the fabrication to local law enforcement is an option, though most landlords and small lenders deny the application and move on. Institutional lenders with compliance departments typically have mandatory reporting protocols to follow.
