    FAQ

    What files can I upload?

    PDFs or photos (JPG, PNG) of tax slips and returns. Canada: T4, T5, T4A, T2202, Notice of Assessment. US: W-2, 1099, 1040. UK: P60, P45, SA302.

    What happens to my files?

    They are read on our server, ID numbers (SIN, SSN, NI number) are removed from the text, and the file is deleted straight after. We never store your documents. Only the redacted text goes to our AI provider to pull out the figures.

    Do I need an account?

    No. No signup, and you can delete your session at any time.

    Do you file my return?

    No. RefundSift gives information only. You claim any refund yourself, or with a professional.

    What if nothing is found?

    The preview is free, so you only pay if there is something worth claiming.
