Tax Code 1257T Explained
What does this code mean?
1257T gives you the same £12,570 Personal Allowance as 1257L, but the T suffix means HMRC has flagged items for review. This might be because your benefits are estimated, you have income that needs checking, or HMRC requires additional information. The tax deduction is the same, but your code may change once HMRC completes the review.
Who gets this code?
Taxpayers with estimated benefits, complex circumstances, or where HMRC is in the process of reviewing your tax affairs.
