0T
Tax Code 0T
What does this code mean?
0T means you have no personal allowance remaining. This can happen if you earn over £125,140 (where the personal allowance is fully tapered away), or if your new employer does not have your P45 details yet. If you earn under £125,140 and have this code, you are almost certainly overpaying tax and should contact HMRC.
Emergency Tax Warning
This is often an emergency or temporary tax code. You might be paying too much tax while on this code.
Who gets this code?
Very high earners (over £125,140) or new starters without P45 info. If applied incorrectly, it leads to significant overpayment.
Is it correct?
Check your latest P45 or Payslip to see if this matches your current situation.
