You can see the amount you've paid in your Compound App, just check the Activity in the home screen.    

Although we are working on making it available for you to download your contribution statements directly from your app soon, for now, please reach  out to Compound to have an official contribution statement on a Compound  letterhead generated for you. Please remember that if you have contributed  into any other pension - separate to Compound - you will also have to add  these contributions on if this is for your self-assessment tax return.    

You will also need to declare how much tax relief you've received on top of  these contributions.

You can do this by:    

Taking your total amount paid into your pension and multiplying it by  1.25.

For example, if you paid in £600, multiply this by 1.25 = £750.

That is how  much you would need to declare in your tax return    

Not to worry, though, your generated contribution statement will also  present all of the tax relief Compound has already added to your contributions as well, or you can see your tax relief total in the Compound  App.
