Landlord and property SPV accountants.

Landlord and property SPV accountants work out whether a portfolio should sit in personal names or in a company, then run the reporting each structure demands. Personally held property is taxed on rental profit with mortgage interest relieved only as a basic rate reduction, while a company deducts interest in full and pays Corporation Tax.

UK property taxation has been reshaped by Section 24 (the mortgage-interest restriction), ATED (the Annual Tax on Enveloped Dwellings), and the residential property CGT 60-day reporting regime. Most generalist accountants get at least one of these wrong, and the cost of errors lands on landlords directly through penalties and missed reliefs.

We work with individual landlords filing on Self-Assessment (SA105), with portfolio landlords running through Limited Company SPVs (typically one SPV per property or per portfolio segment), and with mixed-portfolio operators holding some properties personally and others in structures. Each model has tax consequences and we model them transparently.

For SPV-based portfolios, the dominant structure for buy-to-let above 4 properties, we handle the entity-level bookkeeping, mortgage-interest deductibility (preserved inside Ltd companies), Corporation Tax, dividend extraction strategy, and the inter-company arrangements when groups span multiple SPVs.

From April 2026, MTD for Income Tax begins phasing in for landlords with income above £50,000. We're fully MTD-ready, quarterly digital updates plus the final annual declaration will run inside our standard cycle. The phasing, the qualifying income test and the quarterly cadence are set out in our guide to Self-Assessment and MTD for Income Tax, and the wider UK filing calendar on our UK accounting page.

The question is usually asked because of the finance cost restriction. Since April 2020, interest on personally held residential lettings is not deductible from rental profit at all. Relief is given instead as a reduction in the tax bill worth 20 percent of the finance cost, which means a higher-rate landlord pays tax on income that has already gone to the lender. A company is not caught by that rule and deducts interest as an ordinary expense, which is why incorporation looks obvious on the first page of the calculation.

It stops looking obvious on the second. Moving property into a company is a disposal at market value, so latent capital gains crystallise, and Stamp Duty Land Tax is generally payable by the acquiring company on the same market value. Lender consent, higher SPV mortgage pricing, and the cost of extracting profit from the company all sit on top. Incorporation relief and partnership routes exist but are fact-specific and are not available to most landlords holding a handful of properties passively. We model the whole cost, including the exit, before anyone signs anything.

Whichever structure applies, the reporting calendar is unforgiving. Capital gains on UK residential property must be reported and paid within 60 days of completion under HMRC's report and pay Capital Gains Tax service, which is a separate filing from the annual return and is the single most commonly missed deadline in this sector. Companies holding residential dwellings valued above 500,000 pounds fall into the Annual Tax on Enveloped Dwellings regime, with a return due by 30 April even when a relief reduces the charge to nil. Where a portfolio sits across several SPVs, the consolidated view comes from our monthly management accounts service.

Two further changes are already in the diary. The furnished holiday lettings regime was abolished from April 2025, so short-let properties are taxed as ordinary property businesses and lose the interest, capital allowances and pensionable-income advantages that made them attractive. And Making Tax Digital for Income Tax begins phasing in from April 2026 for landlords with qualifying income above 50,000 pounds, dropping to 30,000 pounds from April 2027. HMRC's general guidance for landlords sits at renting out a property. Personal returns are filed through our Self-Assessment service. Setting the SPV up, including the share structure and the first Companies House filings, runs through our company incorporation service. The rest of what a property business needs each year is listed in our accounting and tax services directory.
