New Income Tax Checker

Yes the "pensioners" additional personal allowance is being frozen out as the standard rate rises to create the squeezed middle.

The calculator is also wrong in thinking that NI is not payable for a woman aged 60. This is no longer true. The calculator needs updating.

Have just used this tool. For a female aged 60-65, the tool calculates zero NI. I pay NI, probably due to the changes in retirement age. Can the tool be updated? Or am I wrong?

No you're not wrong.

Whether it can be updated is up to MSE.

Ok this gives me different figures to my pay slip who is right and who is wrong

Basically when I had my pension contribution it is £84 out the same as the hmrc pension why is this?

I used the tool but was confused as I have a state pension and private pension I earn 27000 per year this is made up of 18500 private pension and 8500 state pension I was not sure which income to enter. As my tax is paid from my private pension and not my state pension. My tax code is 189t but I thought the tax code should end with a P as I am over 65 yrs and retired

The final letter of the code is irrelevant for calculating the tax liability.
Your code number is worked out by taking your untaxed state pension from your personal allowance. This would normally be 10,500 - 8,500 = 2000 and a cde of 200. So you are also being taxed on unearned income of £110.
Your income is, as you say, £27,000 and your tax paid is what ever appears on your private pension documentation but don't forget you also have to enter the £110, what ever it is if indeed it is something and not an HMRC error, to get the right answer.
