When Do Landlords Pay Tax on Rental Income?

A tenant’s rent may arrive every month, but the tax bill rarely follows the same timetable. So, when do landlords pay tax? For most individual UK landlords, rental profits are reported through Self Assessment after the end of the tax year, with tax normally due by 31 January. Depending on the amount owed, you may also need to make advance payments towards the following year’s bill.

That is the simple answer. The practical answer depends on how you own the property, how much profit it makes, whether you have other income, and whether you sell. Missing the distinction can leave a landlord with an unexpected bill at the worst possible time.

When do landlords pay tax through Self Assessment?

The UK tax year runs from 6 April to 5 April. If you receive rental income as an individual landlord, you generally calculate the profit for that period and include it on your Self Assessment tax return.

For example, rental profits earned between 6 April 2025 and 5 April 2026 fall into the 2025/26 tax year. If you file online, the return and any balancing tax payment are normally due by 31 January 2027. The deadline to register for Self Assessment, where needed, is 5 October after the end of the relevant tax year.

You do not pay Income Tax on the total rent received. You pay tax on the taxable profit after allowable costs have been deducted. This could include letting agent fees, landlord insurance, repairs, accountancy fees, replacement domestic items and a share of relevant running costs. Costs need to be genuinely connected with letting the property and properly recorded.

The rate of tax depends on your total income. Rental profit is added to earnings from employment, self-employment, pensions and other taxable income. It may therefore be taxed at the basic, higher or additional rate. A property that looks profitable on a monthly basis can produce a larger tax liability than expected if the landlord is already a higher-rate taxpayer.

Payments on account: why January is not always the whole bill

Many landlords are caught out by payments on account. HMRC usually asks for these when your Self Assessment tax bill is more than £1,000 and less than 80% of the tax was collected at source, such as through PAYE.

A payment on account is an advance payment towards the following tax year. It is based on your previous year’s Income Tax and Class 4 National Insurance bill, where applicable. The two instalments are normally due on 31 January and 31 July.

Say your 2025/26 rental tax bill is £3,000. By 31 January 2027, you would normally pay the £3,000 owed for 2025/26, plus a first payment on account of £1,500 towards 2026/27. A second £1,500 payment would be due on 31 July 2027. That first January payment can therefore be £4,500, not £3,000.

If your income has fallen - perhaps the property was sold, sat empty, or major allowable expenses reduced the profit - you can apply to reduce payments on account. Do this carefully. If you reduce them too far, HMRC can charge interest on the shortfall.

The rental income that needs declaring

Rental income normally includes more than the monthly rent. It can also include payments from tenants for services, non-refundable deposits retained at the end of a tenancy, and income from letting a garage, parking space or furnished room.

There are useful allowances in the right circumstances. The Rent a Room Scheme may allow up to £7,500 of tax-free income where you let furnished accommodation in your own main home. If income is shared with someone else, such as a joint owner, the limit is usually halved. This is not the same as owning a separate buy-to-let property, so do not assume the relief applies simply because you rent out a room or annex.

Property income allowance may also be available where gross property income is £1,000 or less. However, it cannot simply be added on top of claimed expenses. In many cases, you choose between the allowance and deducting actual allowable costs. The better option depends on the figures.

Keep records before the deadline gets close

Good records are not just about completing the return. They show what you have spent, support expense claims and make it much easier to plan for the next payment. Keep rental statements, invoices, tenancy agreements, mortgage interest certificates, agent statements, receipts for repairs and evidence of any periods when the property was empty.

Separate repairs from improvements. Replacing broken kitchen cupboard doors or repairing a roof is usually a revenue expense. Building an extension or making a significant upgrade is more likely to be capital expenditure. Capital costs may help reduce Capital Gains Tax when you sell, but they are not normally deducted from annual rental income.

For individual landlords, cash basis accounting is now the default method in many cases. Broadly, this means income and expenses are recorded when money is received or paid, rather than when invoiced. You can elect to use traditional accounting where that better reflects the business. The treatment can affect timing, particularly around year-end, so it is worth taking advice rather than treating bookkeeping as an afterthought.

Mortgage interest does not work like a normal expense

For landlords who own residential property personally, mortgage interest relief is restricted. Rather than deducting all finance costs from rental income when calculating profit, most individual landlords receive a basic-rate tax reduction based on eligible finance costs.

This matters particularly for higher-rate taxpayers. Rising interest rates can reduce cash profit while leaving taxable rental profit comparatively high. A landlord may therefore have less money in the bank but still face a substantial tax bill.

The rules differ for property held through a limited company. Companies can generally deduct finance costs when calculating taxable profit, but company ownership brings different administration, mortgage availability, tax considerations and costs when extracting money personally. There is no one-size-fits-all answer, especially where a property is already owned personally.

When landlords pay tax after selling a property

Selling a rental property can trigger Capital Gains Tax (CGT). The gain is broadly the sale proceeds less the purchase price, buying and selling costs, and qualifying capital improvement expenditure. Any available reliefs and annual exempt amount are then considered.

For a UK residential property sale that creates CGT to pay, the gain normally needs to be reported and the tax paid within 60 days of completion. This is separate from the annual Self Assessment deadline. If you already complete a tax return, the disposal will also need to be included there.

The 60-day rule is easy to miss because the sale can feel finished once solicitors have completed the transaction. From a tax perspective, it is often only the start of a short reporting window. Get the purchase records, improvement invoices and completion statements together early, particularly if the property has been owned for many years or was once your home.

What if the property is owned by a limited company?

A limited company pays Corporation Tax on its rental profits rather than the owner paying Income Tax directly on the company’s income. Corporation Tax is normally due nine months and one day after the end of the company’s accounting period, while the company tax return is generally due 12 months after the period ends.

For a company with a 31 March year-end, Corporation Tax would usually be due by 1 January of the following year. If the director takes salary or dividends, there may then be personal tax reporting and payment obligations too. The company structure can help some landlords reinvest profits, but it is not automatically the lowest-tax route once all taxes and future sale plans are considered.

Do landlords need to pay VAT?

Residential rents are generally exempt from VAT, so most residential landlords do not charge VAT on rent and cannot normally reclaim VAT on related costs. Commercial property is different. The landlord may opt to tax a commercial property, which can change the VAT treatment of rent and purchase costs.

This is an area where getting the setup wrong can be expensive. If you let shops, offices, workshops or mixed-use property, check the VAT position before signing agreements or issuing invoices.

Plan for the tax bill as rent comes in

A practical habit is to put a proportion of net rental income aside as it is received, rather than waiting for the January deadline. The right percentage depends on your wider income, finance costs and expenses, but the aim is simple: tax money should not be mistaken for spare cash.

If your rental figures are growing, you are dealing with payments on account, or you have a property sale coming up, speak to an accountant well before the deadline. Short And Sons Accountants can help landlords turn records into a clear tax position, so the next HMRC payment is planned for rather than feared.
