Can I deduct my mortgage payments from rental income?

Not directly. Instead you get a tax credit at the basic rate (20%) on your finance costs. TaxGo calculates this credit and applies it to your return.

What expenses can I claim as a landlord?

Allowable expenses include letting agent fees, building insurance, repairs and maintenance (not improvements), ground rent, service charges, accountancy fees and advertising for tenants. TaxGo sorts your receipts into the right categories.

I only rent out one room in my home — do I need to file?

If you earn under £7,500 a year from renting a furnished room in your main home, rent-a-room relief means you usually don't owe tax on it. TaxGo checks your eligibility and applies the relief.

How TaxGo handles it

01
Multiple properties
Own more than one rental? Upload documents for each property and TaxGo consolidates them into one property section — income, expenses and profit calculated for you.
02
Expenses sorted for you
Drop in your receipts and TaxGo identifies what they are — repairs, insurance, letting fees, ground rent — and puts them in the right expense category.
03
Finance cost credit applied
Mortgage interest isn't deducted from rent any more. TaxGo applies the 20% basic-rate tax credit on finance costs for you.
04
Property income allowance
If your gross rental income is under £1,000, you may not need to report it. TaxGo checks whether the allowance or actual expenses works out better.
