Our forms are an improved version of the paper / online HMRC SA100 – SA109 tax return, with helpful hints, adapting as you fill them in. Your return is automatically checked for errors before you send it, with notification that it’s been accepted within 10 seconds.

Non-residents use CalCal to send your return simply and easily.

If you’re self-employed, CalCal’s pre-fill feature asks you for things your specific business is likely to have spent money on. The figures will automatically be filled in to the correct boxes of your tax return.
