WageLens is a UK AI payslip checker that detects tax code errors, underpayments, missing overtime, National Insurance mistakes, pension shortfalls and student loan errors using HMRC 2025/26 rates. Upload your payslip and get a plain-English report in seconds — free preview, full reports from £2.99.
WageLens reads your payslip (PDF, image or text), extracts your gross pay, tax code, NI, pension and student loan figures, then recalculates each value against UK 2025/26 statutory rates and your contracted pay. Any discrepancy is flagged with an explanation and a recommended action.
Yes — a free preview is available at /free-analysis with no sign-up needed. The full detailed report and HMRC/employer correction letter templates require the £2.99/month Pro plan, which you can cancel at any time.
Yes. WageLens validates the tax code on your payslip against the income tax actually deducted, identifies emergency codes (W1/M1/X), K-prefix codes, and BR/D0 misuse, and tells you whether you're overpaying or underpaying.
If you've underpaid tax, HMRC normally adjusts your tax code to recover the shortfall through future PAYE. If you've overpaid, you can claim a refund through your Personal Tax Account on gov.uk or by phoning HMRC on 0300 200 3300.
WageLens uses deterministic UK tax-rule calculations (2025/26 rates) layered on top of AI extraction — numeric outputs are computed, not guessed. Reports are informational and you should verify any concerns with HMRC, your employer or a qualified professional before formal action.
