@HelloCrypto:
1. Next to the "Tax year" label, you will find a link called "custom date range".
Use it if you want to create a tax report from 1 April to 31 March.
2. At the end you will see the total calculated gain for the tax period.
You can just subtract £11,500 from it and multiply it with your tax rate.
But I will put a Capital Gains Tax Allowance on the to do list to make it easier

Hey Dario. Sure, the custom date range is a great feature - without that I would be having major issues! Just saying it would be nice to have a radio button at the top to switch between 'standard calendar years' and 'UK financial years', then if the latter is selected, the drop downs become 01.04.yy - 31.03.yy

Also, when I do input a custom date range and run the report, the value of 'Tax Year' in the table becomes 'Custom' for each report - when you have a few reports there it's hard to follow which one is which, so it would be great if rather than displaying 'Custom', it actually displayed the date range that the user has picked.

Cheers
