What does C1257L mean?
The prefix C stands for Wales. The number and letter, 1257L, work as normal: £12,570 of tax-free pay a year. The prefix only changes which income tax rates are used on your pay.
Why the prefix matters
Income tax on earnings is set separately in Scotland and Wales, so employers need to know which rates to use. If you moved country or your address changed, tell HMRC so your prefix is right.
