Tax return pack (SA105)

Year-end summary of rental income and allowable expenses, mapped to HMRC's SA105 (UK property) form.

This pack is an automated estimate to help you and your accountant — it isn't tax advice, and figures depend on the rent and expenses you've logged. Check it against your records before filing.
What's allowable (key rules)
  • Mortgage interest isn't deducted from profit — it's relieved as a 20% basic-rate tax credit (shown as Box 44). Only the interest counts, not capital repayment.
  • Repairs that restore the property are allowable; improvements are capital and aren't (they may reduce CGT on sale instead).
  • Replacing domestic items (white goods, carpets, furniture) is allowable under Replacement of Domestic Items Relief; the first purchase and upgrades are not.
  • During void periods only your actual costs (council tax, utilities) are allowable — there's no notional “void allowance”.

Mileage claim

Visit miles for this tax year are automatically included in Box 29 below, computed at HMRC tiered rates (45p first 10,000 mi, 25p after). The breakdown table shows the line item.
