The fastest way to spot a fake pay stub is to check the math: on a genuine stub, gross pay minus deductions equals net pay to the penny, Social Security withholding is exactly 6.2% of taxable wages, and year-to-date totals grow logically from one stub to the next. Fabricated stubs almost always fail at least one of those checks, because whoever typed the numbers invented them instead of calculating them.

This guide is written for the people doing the checking — landlords, property managers, loan officers, and employers verifying an applicant's documents — and for honest applicants who want to understand exactly what reviewers look at.

What Are the Biggest Red Flags on a Fake Pay Stub?

Work through this checklist in order. Most fabricated stubs fail within the first five items.

1. The math doesn't reconcile. Add every deduction and subtract from gross pay. If the result isn't the stated net pay — exactly — stop there. Real payroll software never produces a stub that is off by even one cent.
2. FICA percentages are wrong. Social Security withholding is 6.2% of taxable wages (up to the 2026 wage base of $184,500) and Medicare is 1.45% with no cap. Divide the Social Security line by gross pay: if you get 5.8% or 7.1%, the number was typed by hand.
3. Everything is a round number. Real withholding produces figures like $427.83, not $430.00. A stub where gross, taxes, and net are all round numbers is a strong signal of fabrication.
4. Letter O where a zero should be, and other character swaps. Template-edited fakes often contain "O" instead of "0", lowercase "l" instead of "1", or inconsistent decimal formatting ($1,500.00 on one line, $1500 on the next).
5. Fonts and alignment shift between fields. When someone edits a PDF template, the fields they typed over rarely match the original font, weight, or baseline. Zoom in: mixed fonts inside one column are a classic tell.
6. Year-to-date totals don't add up. YTD figures must equal the previous stub's YTD plus the current period — and must be plausible for the date. A $48,000 YTD gross on a March stub for a $50,000/year salary is arithmetic fiction. (See our glossary entry on YTD for how these totals work.)
7. Dates don't match the stated pay frequency. A "biweekly" stub with pay periods 10 days apart, a pay date on a Sunday, or a period end date after the pay date all point to manual invention.
8. Employer details are thin or unverifiable. A real stub carries the employer's full legal name and address. A stub with only a company name — no address, no phone traceable to a real business — deserves a direct call.
9. The template is suspiciously generic. No company identity, placeholder-looking layout, or design that matches known "fake stub" templates circulating online.
10. Net pay is implausibly high. Take-home pay above roughly 85–90% of gross for a normal W-2 employee means taxes are missing or understated. Federal withholding, FICA, and state tax (where it applies) take a predictable bite.

What Should You Check, Line by Line?

Ask for two or three consecutive stubs rather than one. Faking a single stub is easy; faking a sequence in which every YTD column reconciles across periods is where most fabrications collapse.

How Do Landlords Verify Pay Stubs?

Experienced landlords and lenders treat the stub as a claim to be verified, not as proof in itself. The standard verification ladder:

1. Call the employer directly. Look up the company's main phone number independently (never use a number printed on the stub or supplied by the applicant) and ask HR to confirm employment dates and position. Many employers confirm employment even when they won't discuss salary.
2. Cross-check bank statements. Ask for 1–2 months of statements and match payroll deposits against the stub's net pay. Deposits that don't exist, don't match, or arrive on different dates contradict the stub.
3. Use a payroll or income-verification service. The Work Number (Equifax), Truework, and payroll-linked services such as Plaid, Argyle, and Pinwheel pull employment and income data straight from payroll systems, bypassing the document entirely.
4. Request tax documents for larger decisions. Mortgage lenders routinely require W-2s and IRS transcripts (via Form 4506-C), which no fabricated stub can survive.

If an applicant is self-employed, expect tax returns, 1099s, and bank statements instead of employer-issued stubs — our guide on how many pay stubs you need covers the standard alternatives reviewers accept.

Can Landlords Detect Fake Pay Stubs?

Yes — routinely, and usually without any document forensics at all. A landlord does not need to spot a flaw in the stub itself: one phone call to the employer's publicly listed number, or a bank statement whose deposits do not match the stub's net pay, settles it. Larger decisions add payroll-linked verification services and tax transcripts, which a fabricated document cannot survive at all.

The practical consequence is that a doctored stub tends to fail on the outside evidence rather than on its own appearance. Getting the maths and the formatting right does not help when the employer says the applicant never worked there, or when the deposits are absent from the account.

Why Does an Honest Pay Stub Always Pass These Checks?

Because every test above is just arithmetic and corroboration. A stub generated from real earnings — whether it came from an employer's payroll system or a generator fed with accurate numbers — has correct FICA percentages, a net figure that reconciles, YTD totals that grow correctly, and bank deposits that match. Verification only threatens documents whose numbers were invented.

That is also the difference between lawful record-keeping and fraud: creating an itemized record of income you actually earned is legal; putting invented numbers in front of a landlord or lender is prosecutable. Our guide on whether it's legal to make your own pay stubs walks through exactly where that line sits.

Frequently Asked Questions

What is the single most reliable check?

Recompute the stub. Gross − deductions = net, Social Security = 6.2%, Medicare = 1.45%. It takes two minutes with a calculator and catches the majority of fakes.

Can a fake pay stub look completely professional?

Yes — appearance proves nothing either way. Clean design is trivial to fake; internally consistent math across consecutive stubs plus matching bank deposits is not. Judge the numbers, not the layout.

Is it illegal to submit a fake pay stub?

Yes. Submitting falsified income documents to obtain a lease, loan, or job can be prosecuted as fraud under state law — and as bank, loan, or mortgage fraud under federal law when a lender is involved. Penalties scale with the money at stake: fines, restitution, and probation at the low end, felony charges carrying multi-year prison sentences when a lender relied on the document — plus the immediate civil fallout of eviction, loan acceleration, or termination once the fake is discovered.

How do you spot a fake ADP pay stub?

The same way as any other — the ADP look is easy to imitate, so the layout proves nothing. Run the math checks above (6.2% Social Security, reconciling net pay, YTD continuity), then look for ADP-specific structure: a genuine ADP earnings statement carries the company code, file number, and department reference fields in the header, statutory taxes listed before other deductions, and rate/hours/this-period/YTD columns that multiply out exactly. Our ADP-style template page describes that layout element by element, which makes a useful checklist. When in doubt, skip the document: employment run through ADP can be confirmed via The Work Number or by calling the employer.

Is there a fake pay stub detector?

There is no magic scanner, but payroll-linked verification comes close: The Work Number (Equifax), Truework, and bank/payroll-connection services such as Plaid, Argyle, and Pinwheel pull employment and income data straight from the source, so a fabricated document simply never enters the picture. Some proptech screening tools also run automated document forensics (metadata, fonts, template fingerprints) on uploaded stubs, but their output still needs the manual checks in this guide — recompute the math, demand consecutive stubs, and match deposits against bank statements.

Do verification services catch every fake?

Payroll-linked verification (The Work Number, Plaid-style connections) is very hard to defeat because it never relies on the document. Manual review catches most fakes too, but only if the reviewer actually runs the math and calls the employer.

What should I do if I suspect a stub is fake?

Don't accuse — verify. Ask for consecutive stubs and bank statements, call the employer through an independently sourced number, or run a verification service. A genuine applicant's documents will corroborate each other; a fabricated stub will stand alone.

Bottom line: fake pay stubs fail on arithmetic, consistency, and corroboration — wrong FICA math, round numbers, YTD totals that don't add up, and bank deposits that don't exist. Run the checklist, verify through an independent channel, and remember that a stub built from real earnings passes every one of these tests by construction.
