Welcome to CGTCalculator - keep track of your capital gain
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.
Anyone who has tried working through the Inland Revenue matching
rules for share trades will know that the process can quickly become very
complicated. This is especially true if you have made more than a couple of dozen
or so trades, if you have
taper relief to
take into account or if one or more of your shares has changed
status from a business asset to a non-business asset (or vice versa!) during
the period of ownership. This calculator will make it easy.
