Detect tampered and deepfake P60

What a genuine P60 contains

The form covers a single tax year running 6 April to 5 April, and prints the employer's name and PAYE reference, the employee's name and National Insurance number, and totals for pay, tax deducted, NI, and any student loan repayments or statutory payments. Employers must issue it by 31 May following the year end.

The P60's totals must agree with the final payslip's year-to-date column, and the National Insurance number and PAYE reference must agree with the payslips and employment elsewhere in the file. A P60 whose totals float free of the payslips behind it, or whose employer details shift between documents, is the composite signal lenders care about.

How P60 forgeries are made

• Payslip reconciliation

  The P60's closing totals must match the final payslip's year-to-date figures for the same employment. Totals that float above the payslips behind them are the inflation pattern this document exists to catch.

• Tax-year coherence

  The label covers 6 April to 5 April of consecutive years. Mismatched year labels, or totals for a period the employment dates cannot span, point at retyped numbers.

• Reference and NI structure

  The employer's PAYE reference and the employee's National Insurance number follow fixed formats, and both must agree with the payslips and employment letters in the same file.

• Figure-level print forensics

  Edited totals betray themselves through font passes, digit spacing, and realigned columns inside the totals table, since amounts are usually the only region a forger touches.

What TamperCheck checks on a P60

TamperCheck runs 200+ forensic checks across three layers and returns a risk score from 0 to 100 with plain-English findings tied to specific regions of the document. These three carry the most weight on this document class.

• Table structure integrity

  Inserted and deleted rows leave structural artifacts behind: inconsistent spacing, misaligned columns, and formatting the visible table no longer accounts for.

• Date and validity consistency

  Issue, expiry, and period dates are checked against one another and against the file's own creation metadata, which catches backdating and validity extension.

• Reference and document number checks

  Document, account, and reference numbers are checked for issuer format conformance and against every other place the same value appears on the page.

• And many more checks

  The three above are the layers that carry the most weight on a P60. Every upload runs the full suite of 200+ checks regardless of document class, spanning file structure and metadata, pixel-level forensics, font and text rendering, optical and print characteristics, provenance signals, AI-generation signatures, and many more checks.

Who verifies a P60, and why

UK mortgage lenders, letting agents, and visa financial reviewers. In each case the document is being used to unlock money, access, or a legal status, which is exactly what makes it worth forging.

How to verify a P60 in 4 steps

1. 1

   Collect the P60 and payslips

   Gather the P60 alongside at least the final payslip of the tax year, since the reconciliation runs between the two documents.

2. 2

   Reconcile the totals

   Compare the P60's pay and tax totals against the final payslip's year-to-date column for the same employment.

3. 3

   Check identifiers and dates

   Confirm the tax-year label, PAYE reference, and National Insurance number agree with the rest of the file.

4. 4

   Run a forensic check on the file

   The reconciliation is arithmetic, but inflated totals still need edited cells to carry them. TamperCheck runs 200+ forensic checks including totals reconciliation and cell-level print analysis, returning a risk score from 0 to 100 with findings tied to specific regions of the image.
