How to Spot Fake Pay Stubs: A Guide for Lenders and Landlords

Search for "pay stub generator" and you'll find dozens of sites that will produce a professional-looking stub for the price of a sandwich. Most exist for legitimate reasons — contractors and small businesses need payroll paperwork too. But the same tools show up constantly in rental applications and loan files, filled with income that doesn't exist.

If you're a landlord, property manager or lender, learning how to spot fake pay stubs is one of the highest-return skills in your process. Here's what the fakes get wrong.

Start with the math, because the math is hard to fake

A real pay stub is the output of a payroll system doing precise, boring arithmetic. A fake is a form somebody filled in by hand. That difference shows up in the numbers almost every time.

Step 1: Check gross-to-net. Take the gross pay, subtract every listed deduction, and see if you land on the net. On generated fakes it's frequently off — the author typed a net figure that "looked right" without doing the subtraction.

Step 2: Check the year-to-date columns. YTD figures are where fakes fall apart. If this is the pay period ending June 30 and the applicant is paid twice monthly, gross YTD should be roughly twelve times the period gross. YTD that's suspiciously round, doesn't scale with the pay period, or is smaller than a previous stub's YTD is a hard stop.

Step 3: Sanity-check the withholdings. Federal and state tax, Social Security and Medicare aren't creative-writing fields — they follow published rates. A $6,000 monthly gross with $150 of total withholding isn't an aggressive accountant. It's a fake built by someone who didn't know what the numbers should be.

Then the document itself

The stub is a document, and documents carry their own evidence:

• The employer details. Does the company exist, at that address, with a phone number that answers? A two-minute business lookup settles this. Fakes love real company names with wrong addresses — close enough to survive a lazy check.
• The formatting fingerprint. Real payroll providers have consistent, distinctive layouts. If the applicant supplies three months of stubs, the format should be identical across all three — same fonts, same alignment, same field order. Stubs that drift are stubs made one at a time.
• The file's metadata. A stub supposedly issued monthly by a payroll platform, delivered as a PDF that was created yesterday with a design tool and modified twice since — that file is telling you its own story, and it isn't the applicant's story. This is where automated document scanning earns its keep: fonts, metadata and editing traces on every application file, not just the ones that felt off.

The verification that beats all of it

Document checks filter out most fakes. For anything that matters — a mortgage file, a high-value lease — pair them with verification the document can't fake: employment confirmation through a number you found independently (not the one printed on the stub), or bank deposits that corroborate the claimed income.

The order matters, though. Verifying employment on every applicant is expensive; scanning every document is cheap. Filter first, verify what survives.

What a fake usually costs you

For a landlord, a tenant who inflated income by half is a tenant heading toward arrears and an eviction that eats months and thousands. For a lender, a synthetic income file is a charge-off waiting to season. Set against that, minutes of document checks per application is about the cheapest underwriting control that exists — and it's the same problem lenders face at scale.

Frequently asked questions

What's the most reliable sign of a fake pay stub?

The year-to-date columns. Faithfully maintaining YTD figures across a series of fake stubs requires spreadsheet-level discipline, and most fraudsters don't bother. Cross-check YTD against the pay period and against any earlier stubs in the file.

Are online pay stub generators illegal?

The generators themselves, no — self-employed people and small businesses use them legitimately. Using a generated stub to misrepresent income on a loan or rental application is fraud in most jurisdictions.

Can I detect a fake stub without calling the employer?

Usually. The arithmetic, formatting consistency, employer existence and file metadata catch the large majority. Treat employer verification as the confirmation step for documents that survive those checks, not the first move.

Do these checks work on scanned or photographed stubs?

Yes, with a shift in emphasis. A photo destroys file metadata but exposes image-level evidence instead — pasted regions, resolution seams, clone marks. And the arithmetic never stops applying.
