.xlsx .xls .csv

We auto-detected your columns. Review and adjust the mapping to match HMRC's required fields.

Authorise this tool via Government Gateway to submit your quarterly updates. This uses HMRC's OAuth2 flow.

Demo mode. The submission step is simulated: nothing is sent to HMRC, and the payload shown is a preview only.
Accepts .xlsx, .xls and .csv files. Choosing a file sends it to this site’s server so it can be read. It is not processed only in your browser.
Expenses are mapped to the ten fixed categories listed in the tool. Check each mapping yourself against HMRC’s guidance for your trade.
Transactions are grouped into quarters by date. Check the grouping matches the update periods you actually use.
This is a preparation aid, not tax advice and not a submission service.

Digital Adaption also helps UK firms with reporting and data migration.
