How property landlords must track rental income across multiple properties

Owning several rental properties does not usually mean sending a separate MTD quarterly update for every address. For an individual landlord, the starting point is the property business, rather than the number of front doors.

That is helpful, but there is still a distinction between the information you send HMRC and the detail that makes your own records useful. You need to understand which rent, repair or finance cost sits behind the totals.

Here is how UK properties, overseas properties and shared costs fit together under Making Tax Digital for Income Tax.

Your UK lets normally form one UK property business

An individual’s UK property letting activities normally form a single UK property business. This can include residential and commercial lets, as well as the individual’s share of jointly let property. HMRC explains the underlying position in Property Income Manual PIM1020.

For MTD, the software aggregates the relevant UK property records into one quarterly update for that business. A portfolio of three personally owned UK rental houses does not ordinarily create three separate quarterly filing obligations.

This is different from a limited company holding property or a genuine property partnership. The legal ownership and the arrangement under which income arises matter. Do not combine company receipts with your personal property business merely because you own the company too.

Are records by property address mandatory?

HMRC’s MTD guidance explicitly says that you do not need separate digital records for each UK property. The legal requirement should not be overstated. Read HMRC’s digital records guidance.

Nevertheless, attaching an address or property reference to transactions is often very useful. It helps you answer practical questions: which tenant is behind on rent, where repair costs are rising, and what documents support a particular expense?

It also makes a portfolio easier to hand over to an accountant. A total labelled “repairs” may be enough for a reporting category, but the invoice and property reference explain what happened.

Treat property-level detail as sensible management practice for UK lets, rather than an invented additional MTD obligation.

Foreign property is a separate business

Foreign property income belongs to a separate foreign property business. It should not be mixed into the UK property quarterly totals.

HMRC’s current guidance requires separate digital records for each individual foreign property, including your share where it is jointly let. Those records are then combined into a quarterly update for the foreign property business.

For example, two Spanish properties and one Polish property form part of one foreign property business for this purpose. Keep each property distinguishable in the records and use software that supports the necessary overseas information and year-end tax treatment.

Currency conversion and any foreign tax relief questions also need attention. A single GBP transfer from an overseas agent may not provide all the information needed to calculate the UK tax position.

Worked example: three UK houses and one overseas flat

Assume Martin owns three UK houses personally and also owns a flat overseas. All four are within his digital obligations, and none is held through a company or partnership.

Martin’s UK income total is £10,800. His foreign property income total is £2,700. Subject to any other relevant income and adjustments, those belong in separate business updates.

The example assumes the income is reportable in that period under the accounting basis being used. It does not establish a tax bill, and the overseas amount would need appropriate supporting conversion records.

Martin can keep property references for all four lets. The records for the foreign flat must remain separately identifiable, while property references for the UK houses also help him manage the portfolio.

How to handle repairs and shared overheads

Costs for one property

If a plumber repairs a leak at house B, attach the invoice to house B’s records. The cost can then flow into the appropriate UK property expense category, subject to the normal deductibility rules.

A payment to a builder does not automatically mean an allowable repair. An extension or substantial improvement can have a different tax treatment. Keep enough detail to distinguish the work carried out.

Costs covering several properties

Suppose Martin pays £900 for an insurance policy covering the three UK houses. If the insurer’s schedule attributes £400, £300 and £200 to the properties, those figures provide a straightforward management allocation.

Record the £900 expense once in the business records, with the supporting split. Avoid adding the full invoice and then adding the three allocated amounts again.

Where no exact split is supplied, use a reasonable, documented method if an allocation is needed. A split between UK and foreign activity, or between business and private use, can affect the tax treatment and needs particular care.

Mortgage interest needs its own treatment

For individual residential landlords, the restriction commonly called section 24 generally means qualifying finance costs are not deducted in the ordinary way when calculating taxable property profit. Instead, relief is given through a basic-rate tax reduction, subject to statutory limits.

This restriction originated in section 24 of the Finance (No. 2) Act 2015. HMRC’s residential finance-cost guidance explains the calculation and limitations.

The quarterly reporting categories distinguish residential finance costs from other expenses. Even where a landlord can use simpler income-and-expense totals, relevant residential finance costs still need separate treatment. See the quarterly update direction.

Do not categorise the whole mortgage payment as an expense. The capital repayment and interest are different components.

A simple finance-cost illustration

Suppose an individual residential landlord has £24,000 rent, £4,000 other allowable revenue expenses and £6,000 qualifying mortgage interest.

The simplified taxable property profit before other adjustments is £20,000, rather than £14,000. The potential basic-rate reduction associated with £6,000 interest is £1,200, if the statutory limits permit full relief. It is not an automatic cash refund.

Commercial property borrowing and mixed-use arrangements can have different treatment. Keep those amounts identifiable instead of applying the residential restriction to every loan indiscriminately.

Joint owners report their own position

Your records should reflect the share of income and expenses taxable on you. Two joint owners do not normally submit a single personal MTD update between them.

There are also easements for jointly let property, including an option to report income during the year and provide the related expenses before completing the annual return. Conditions apply, and expenses for solely owned properties are treated separately. Read HMRC’s digital record-keeping direction.

Agree the ownership shares, information timetable and reporting approach before the next submission. If the agent only sends a net statement, ask for the detail needed to understand it.

Give each transaction a clear home

Start by separating UK and foreign property businesses, recording the correct ownership share and identifying residential finance costs. Then add property references and supporting documents that make the portfolio easy to understand.

Avona.app provides property record-management tools at the core self-service price of £15/month. Review the supported property features against your portfolio, especially where overseas income or joint ownership is involved.

Clear records let the software produce useful totals and give you a better view of the properties behind them.
