How much tax will I pay on 1257L?
1257L is a UK PAYE tax code established by HMRC. It generally links to the standard Personal Allowance of £12,570. It is not related to the US Tax system.
It presents payroll and how much income can be paid before Income Tax is taken. Then the rest is taxed by taking the UK rates that apply to you into consideration.
Three things that have the potential to vary the amount taken from each payslip:
- The pay across the tax year
- Any extra letters / markers on the code — for example, W1/M1 for “month 1”
- Whether you fall under England/Northern Ireland, Scotland or Wales law
Why doesn’t 1257L set your US tax?
If your paycheck is from a US employer, 1257L won’t affect that paystub because it belongs to the UK system.
In the US, withholding is established on the Form W-4 and federal law. In parallel, the important dollar amounts are the taxable wages & the amounts withheld.
How is a Washington paycheck calculated?
A Washington paycheck is typically gross pay minus federal withholding, FICA, and WA payroll premiums, along with any benefit deductions.
Washington has no personal state income tax. Hence, the state items you see are frequently program premiums rather than an income-tax line.

A WA salary calculator process can be outlined as below:
- Start with gross wages for the pay period
- Remove pre-tax benefits — if any
- Minus the tax amounts as well as premiums above to reach net pay
