Should you be on tax code 1185L?

An L-suffix code with a number other than 1257 means your Personal Allowance has been adjusted up or down. Common reasons: unpaid tax from a previous year, small benefits in kind, Marriage Allowance (M / N suffixes instead), or company car/fuel benefit. Check your latest P2 coding notice to see exactly why.

How to fix it if 1185L is wrong

  1. Check your current code in the HMRC app, your Personal Tax Account, or your latest P2 coding notice or payslip.
  2. New job with no P45? Ask your employer for a Starter Checklist — completing it correctly is what moves you off a temporary code.
  3. Not sure what your P45 figures mean, or already overpaid? See the P45 box-by-box guide to decode what your employer reported, or run the tax refund estimator to check what you might be owed.
  4. If HMRC agrees your code was wrong, most in-year corrections refund automatically through payroll; larger over- or underpayments are settled via a P800 calculation after the tax year ends.
