I just relocated to UK, and I received my very first payslip. I run some simulations on salary calculators, to understand how much I would have received in my bank account. The payslip states the following:
Gross pay: X GBP NIAble pay: X GBP Taxable pay: X GBP Tax (PAYE): ~ X / 4 National insurance: ~ X / 11 Net pay: ~ X / 1.7
So, I understand that the net pay is the gross pay subtracted with tax and NI, but I have some doubts on how these are calculated, since I get different results in salary calculators online, where the taxable amount is lower than the gross. My annual gross was ~ X * 13 at that time.
Why is the taxable amount the same as the gross amount?
