Payslip / YTD check
Check whether your payslip deductions look broadly right
This is one of TaxDecod’s strongest differentiators. Use it when PAYE, National Insurance, or year-to-date totals feel off and you want a first-check reading before going deeper.
Current tax-year framing
This payslip checker uses 2025/26-style UK salary assumptions and annualised pay to estimate whether your year-to-date Income Tax and National Insurance look broadly on track.

Why this page matters
This is where salary tools become more useful than generic calculators
A salary number can look fine while a real payslip still feels wrong. This route exists to help users test whether tax and National Insurance paid to date look broadly aligned, instead of guessing from one payslip line in isolation.
YTD payslip checker
Check if your payslip deductions look right so far
This tool uses your gross pay to date and compares your paid tax and National Insurance with an estimated year-to-date reading.
Best use
Mid-year payslip check
Best inputs
YTD gross, tax, and NI
Step 1
Enter your year-to-date payslip numbers
Use your payslip year-to-date values where possible. This works best once you already have a few months of payroll history.
Step 2
Read the year-to-date signal
This is a first-check PAYE signal, not a payroll or HMRC ruling.
Headline reading
Your deductions may be running low
Based on your year-to-date pay, one or more deductions look lower than the estimated year-to-date amount. This can happen when tax catches up later, or when payroll timing and cumulative PAYE have not fully evened out yet.

This is a year-to-date estimator using annualised pay. It is useful for a first check, but PAYE timing, bonuses, tax code changes, salary sacrifice, and irregular income can make actual payslips differ.

Decode the tax code first
Use this when the payslip feels wrong and the tax code may be the reason deductions look unusual.
Check for refund or underpayment
Use this when the year-to-date tax paid may be too high or too low overall.

Follow-up and saving
Send your payslip check to your email
Keep the year-to-date reading for later if you want to compare it with a later payslip, P60, or another salary setup.
For now, the most reliable way to keep this result is to save the route where available, bookmark the page, or return through the same salary path later. This keeps the experience calm and avoids promising a delivery step that is not central to the product.
