Self-Assessment for Landlords.
Letting a property – whether a single buy-to-let or a growing portfolio – is a significant business venture. We help you build a tax-efficient property business, not just file a return.
Rental income: understanding your tax obligations
All income from buy-to-let property is subject to Income Tax – but what you actually pay depends on your income profile and how well you use the reliefs available.
Net rental profit
You are taxed on profit, not turnover – every allowable cost is deducted first.
Mortgage interest relief
No longer deducted as an expense – it now qualifies for a 20% basic-rate tax credit instead.
Higher-rate taxpayers
Strategic planning to mitigate rental income pushing you into a higher bracket.
Maximising your returns: allowable expenses
One of the most common ways landlords overpay tax is by not claiming everything they are entitled to.
Letting & management fees
Agent and management fees, fully deductible.
Repairs & maintenance
Not improvements – genuine repairs and upkeep.
Council tax, utilities & insurance
Ongoing running costs of the let property.
Legal fees for tenancy agreements
Up to 7 years of agreement-related legal costs.
Accountancy fees
Our own fees are an allowable expense.
Replacement of domestic items relief
Furnishings, white goods and carpets when replaced.
Joint buy-to-let properties
If you own a property with a spouse, civil partner or business partner, how you declare the income can significantly change your combined tax bill.
HMRC typically assumes married couples and civil partners are entitled to 50% of the income each ("joint tenancy"). If you own as "tenants in common" with unequal shares, you can elect to be taxed on your actual beneficial ownership via Form 17 – Declare beneficial interests in joint property and income.
To use Form 17 you need evidence that your beneficial interests are unequal – usually a Declaration of Trust (or Deed of Trust) or a formal partnership agreement. If you are a higher-rate taxpayer and your spouse is basic-rate, structuring ownership so they hold a larger share can produce substantial savings. We handle the joint tax planning and paperwork so it withstands any HMRC challenge.
