How we prepare your rental income tax return
If you earn income from renting out property, you need to tell HMRC. That means registering for Self Assessment and filing a tax return each year. We handle the entire process for landlords across Cardiff, the Vale of Glamorgan, Newport, and the wider South Wales area.
We start by gathering your records: rental income statements, bank records, receipts for repairs, insurance, letting fees, and any other expenses. Then we calculate your taxable profit by deducting every allowable expense from your total rental income. Once we've prepared your return, we review it with you, answer any questions, and submit it directly to HMRC using approved software.
We make sure you claim every deduction you're entitled to, so you never pay more tax than you need to.
More information
What counts as an allowable expense?
You can deduct the cost of maintaining and running your rental property. That includes repairs and maintenance, buildings and contents insurance, letting agent fees, utility bills if you pay them, council tax, cleaning, gardening, and advertising for tenants. Mortgage interest has restrictions if you're an individual landlord, but we'll work out exactly what you can claim based on your circumstances.
One thing that catches landlords out is the difference between repairs and improvements. Fixing a broken boiler is allowable. Replacing it with a brand-new system might not be, depending on the specifics. We help you get this right so your return stands up if HMRC ever asks questions.
Deadlines and compliance
If you're new to rental income and earn more than £1,000 from property in a tax year, you must register for Self Assessment by 5 October following the end of that tax year. Your return is then due by 31 January, and any tax owed is due the same day. Miss those dates and you'll face penalties, even if there's no tax to pay.
We keep track of every deadline for you. You'll never have to worry about missing a filing date or a payment, because we'll remind you well in advance and make sure everything is submitted on time.
Local landlords, local knowledge
We work with buy-to-let landlords, HMO operators, and anyone renting out a second property across Cardiff and South Wales. Whether you own a terrace in Cathays, a flat in Cardiff Bay, or a house in Penarth, we understand the local market and the expenses that come with it. If you're claiming for repairs after a tenant moves out or deducting costs for a property manager, we know what HMRC expects to see.
Once your return is filed, we're still here if HMRC writes to you with questions or if you need advice on structuring your property business more tax-efficiently. You'll have a direct point of contact and a team that knows your situation inside out.
