UK Investment Tax Calculator
Browser-based UK capital gains and dividend tax calculator for Interactive Brokers exports.
What it does
Works out UK capital gains and dividend tax from Interactive Brokers Flex Query XML, with limited CSV import for three other brokers and manual corporate actions, applying same-day, bed-and-breakfast and Section 104 matching and offshore fund excess reportable income. It runs entirely in the browser, so trade data stays on your machine. Options, the ii parser and PDF export are experimental.
Where it fits on the map
Not on the map: for individual taxpayers.
The map places maintained projects for a company tax department or a tax authority, without a demo or paid-service flag. Everything else stays on the list with its label.
