Have I overpaid tax?

DE_612183

your tax for 2021/22 should have been £9.1k 

You actually paid £8.3k

£4000 gives you an additional £800 tax free - the difference between £9.1 and £8.3 is the £800 less tax you should pay.

You have paid £800 less than you would have done - I think perhaps where your figures may be getting skewed is that you are not taking into account high tax bracket?

Penny has dropped... I think. 

My tax for the year was only £7,550. The the additional £800 on my P60 for tax is actually offset by the £800 automatic top up that is applied to my £3,200 SIPP contribution. 

I knew I was missing something somewhere.. 

Ah well got there in the end...

It's always worthwhile asking the question - you can never rely on HMRC

Personal contributions to a SIPP are paid using the relief at source method.

This means you get 25% added to your payment (20% of the gross contribution) and your basic rate band is increases by the gross contribution.

So in your example you paid £3,200 and £800 in basic rate tax relief was added making a gross contribution of £4,000.

Your basic rate band for 2021:22 is increased from £37,700 to £41,700.

What method is used to make your normal contributions?

Usually one of relief at source, net pay or salary sacrifice.
