What you need
You only need the file or text you want to work with and a modern browser. No install, no account, and no upload to a third-party server.
Steps
- Open the Tax Calculator tool.
- Add your file or paste your input.
- Choose any options the tool offers.
- Download or copy the result.
Why do this in the browser?
Browser-based tools process data on your device. That keeps contracts, photos, drafts and personal numbers private, and it is usually faster than waiting on an upload.
Tips
- Keep a copy of the original file before you overwrite anything.
- Double-check the output before you share or print it.
- If a result looks wrong, adjust options and try again — the original stays untouched on your device.
