Each joint owner reports their own share of the rent and expenses on their own tax return.
If you live with your spouse or civil partner and own a rental property jointly, you'll normally be taxed on an even split of the income, whatever your actual ownership shares. To be taxed on your real shares, the beneficial interests must actually be unequal (for example under a declaration of trust or deed). You then send HMRC Form 17 with that evidence (gov.uk).
Unmarried partners, friends and family members are generally taxed on their share of the income, in line with what they actually own and their arrangement.
Each joint owner can use their own £1,000 property allowance against their share of gross rent (gov.uk).
Set each property's ownership % once on the tracker's Properties tab. Then enter rent and costs at 100%, and your share is worked out on every line and in the SA105 and MTD totals. This is general information, so check unusual arrangements with an accountant.
Keep MTD-ready records for every property with the UK Landlord Property Tracker (£12), or try the free Section 24 calculator.
