Calculating tax from my payslip?

w00519773

I had a slight inflation salary increase this month from my employer, which was backdated to January 1st.  Here are the values:
Salary 3,600
Salary (Back Pay) 75.58
Pension Salary Sacrifice -144
Pension Salary Sacrifice (Back Pay) -3.82 
What should the tax and NI be on this? My tax code is: 1282L as I am working from home.  My tax code changed from 1250 to 1282 in December last year.
Please note the values are slightly different (but in exact proportions).   The actual values are less than the ones quoted.

Not sure if I am missing something here; but what is the point of working out tax/NI on these figures if they are not the actual figures.

These are simple calculators you can use.

As your tax code is cumulative no one here can calculate the tax as that will depend on what is included (taxable pay and tax deducted) from your previous pay slip.

But all things being equal expect to pay 20% tax on the additional pay (net of the salary you have agreed to forego).

And 12% National Insurance.
