Welcome to CGTCalculator - keep track of your capital gain
Anyone who has tried working through the Inland Revenue matching
rules for share trades will know that the process can quickly become very
complicated for even a modest number of trades. The 30 day rule especially can cause unexpected gains/losses.
The purpose of this site is to help UK tax payers to calculate, and to
keep track of, their capital gain (or loss) based on their share trades. This is
important for effective tax planning and can potentially save you a significant
amount on your tax bill.
To use the capital gains calculator simply store your trades in a spreadsheet, or a simple text
editor like Notepad, in a simple format.
If you use an online stockbroker then check the conversion utilities for a suitable converter.
Also note that rights issues and transfers to spouse are supported.
This calculator is updated every tax year and is fully up to date for 2014-2015.
