Quarterly prep checklist

Stick it on the fridge. Deadlines: 7 Aug · 7 Nov · 7 Feb · 7 May.

1. Two weeks before the deadline

  • Download the quarter's bank statement (CSV) from your bank
  • Import it into your MTD software and confirm the suggested categories
  • Add any cash income or expenses that never touched the bank
  • Photograph and attach receipts for anything unusual or large

2. One week before

  • Check mortgage interest sits under "finance costs" — not repairs or other
  • Jointly-owned property: confirm only your share is being reported
  • Compare the quarter's totals against your own expectations — investigate surprises
  • Chase any missing invoices from letting agents or contractors

3. Deadline week

  • Review the final quarterly figures, category by category
  • Submit the update before the 7th
  • Save/print the confirmation for your records
  • Glance at your year-to-date tax estimate — no January surprises
