Summarise a Year of Spending for Your Self-Assessment Tax Return

The Self Assessment deadline is approaching and your records are a shoebox of receipts and bank entries. This organises the year: every income source totalled, allowable expenses grouped by HMRC category, and a provisional tax position so there's no nasty surprise. You arrive at the return knowing your numbers, not guessing them.
