Is There a Fake Pay Stub Detector? What Actually Catches One

If you’re searching for a “fake pay stub detector” or a “pay stub checker,” you’re probably hoping for a box you can drop a document into that says real or fake. Here’s the honest answer: a tool can catch a lot — but the fakes that actually cost landlords money slip past anything that only looks at the document. Here’s what a detector can and can’t do, and the one check that exposes the convincing ones.

What an instant detector can actually catch

A good automated check reads things your eye can’t, and catches the lazy fakes fast:

• Hidden file metadata — whether the document came from a payroll system or was built in Photoshop, Canva, or Word.
• The math — gross-to-net, year-to-date, and whether the tax lines hold together (Social Security and Medicare sit in a fixed 4.28-to-1 ratio a forger usually gets wrong).
• Tax logic against the state — state income tax on a stub from a no-income-tax state, for instance.

That catches the careless fakes. The problem is the careful ones.

Why the best detector still misses the worst fakes

Here’s the trap. Every check above looks at the *document*. But the most damaging fraud isn’t an *altered* document — it’s a *perfect* document for an employer that doesn’t exist. Someone invents a company, makes a clean, internally-consistent pay stub for it, and every “is this edited?” detector waves it through, because technically nothing was edited. The math adds up. The metadata’s clean. And the income is entirely fictional. That’s the invented-employer scam — exactly what a document-only checker can’t see.

The check that actually catches it

The only thing that exposes an invented employer is stepping *outside* the document and confirming the company is real: registered with the state, a genuine commercial address on a map, a phone that independently reaches the business, an online footprint. Here’s how to check whether an employer is a real company — and why you should never call the number printed on the stub.

So — is there a tool that does all this?

You can do a surprising amount yourself with our fake-pay-stub checklist — the file, the math, the taxes. The part that’s genuinely hard to do by hand is the employer side: pulling the state registry, confirming the address is a real office, finding an independent phone and web presence. That’s the piece ProofSweep automates. It isn’t an instant browser gadget — it’s a real check, run properly, that reads the document *and* verifies the employer behind it, with a plain-English report in 24 hours.

The employer side is the hard part to do by hand — and it’s exactly what ProofSweep automates. Upload a pay stub and get the document and the employer both checked, in a plain-English report within 24 hours. Not a background check; just the income documents, done right.
