Overview

Rental income and your tax return

If you receive rental income from UK property you normally need to report it on a Self Assessment return, using the SA105 UK property pages. The rules on expenses, mortgage interest and joint ownership are easy to get wrong.

We prepare your rental income and expenses, apply finance cost relief correctly, split joint income fairly and tell you exactly what you owe. We can also help with capital gains tax when you sell a property.

This service is for you if…

You own one or more buy-to-let properties
You rent out a room or a second home
You own property jointly with a partner or family member
You have mortgage interest on rental property
You have sold or are selling a rental property
Your rental income is over £1,000 a year

Know the rules

Key Self Assessment rules for landlords

The property allowance gives you £1,000 tax-free property income, but you cannot also claim expenses against that income.
Residential mortgage interest is not deductible; instead you get a 20% basic rate tax credit.
Jointly owned property is normally taxed 50:50 between spouses unless you make a declaration for different shares.
Repairs are allowable; improvements are capital and are dealt with when you sell.
From 6 April 2026, Making Tax Digital for Income Tax applies to landlords with qualifying income over £50,000.
Selling UK residential property may require a 60-day capital gains return. See capital gains tax returns.

 Trustindex verifies that the original source of the review is Google. I highly recommend Imran to anyone looking for a reliable and knowledgeable accountant. He helped me sort out a very complicated backlog of accounts and prepared my overdue tax returns with professionalism and attention to detail.

Throughout the process, he was incredibly patient, took the time to answer all of my questions, and explained everything clearly. He guided me through each step and helped rectify issues that had built up over time, making what felt like an overwhelming situation much more manageable.

I'm very pleased with the service I've received and truly appreciate his support. If you need help with your accounts or taxes, I would highly recommend Imran.

 Trustindex verifies that the original source of the review is Google. We worked with a few different accountants before finally settling with Accotax, and we’re really glad we did.

Their team is great. Abdul is responsive and easy to reach whenever I have a question, which makes a big difference. They take the time to understand how our business works and what our needs are. They are very knowledgeable, and when they don’t have the answer straight away, they take the time to look into it and get back to us quickly.

Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing. She is professional, efficient, and follows the processes we have put in place together. She's also very quickin getting back to us whenever needed. We’re very happy to work with her and hope to continue doing so for as long as possible.

Overall, Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow.

I would 100% recommend them.

 Trustindex verifies that the original source of the review is Google. I have really impressed to date with all dealings with Accotax highly enough. From day one, they've made what can often be a complicated and stressful part of running a business feel straightforward and hassle-free.

A special mention has to go to Anum, who has been friendly, incredibly responsive, and genuinely cares about providing the best possible service. No question is ever too much trouble, and she consistently goes above and beyond to make sure everything is dealt with efficiently.

I wouldn't hesitate to recommend you to anyone looking for an accountant they can genuinely trust.
