Now we are in the new tax year, it may be a suitable time to check your tax code. Millions of employees are probably not on the tax code that is appropriate to them.
If your annual earnings are under £100,000, then you are likely to be entitled to an amount of free pay of £12,570. This is represented by a tax code of 1257L.
Some couples where they qualify.may share an amount of 10% with their partner.
Others may have benefits or prior year tax debts which can impact their tax code making the free pay entitlement included in their tax code lower.
Many new employees don’t realise that they should have completed a starter checklist or didn’t have or forgot to provide their new employer with form P45 from their old employer before their first new pay day. They will have been placed on a 0T tax code and have no tax free pay and are likely to be paying too much.
Your tax code is used by your employer or pension provider to work out how much Income Tax to take from your pay or pension. HM Revenue and Customs (HMRC) will tell them which code to use.
