Digital records include the date, amount and category of each business or property transaction. You keep this information directly in your software of choice, or in a spreadsheet that connects to HMRC through bridging software.
When it comes to proof of expenses, the good news is you don’t necessarily need to scan or upload every individual receipt. You only need accurate digital records of the transactions. That said, it’s a good idea to keep any receipts separately, in case HMRC asks for evidence of them later.
