If you own rental property in Oldham or anywhere across Greater Manchester, the chances are your tax affairs are more involved than you might expect. Many landlords we speak to discover — sometimes too late — that the rules governing property income, allowable expenses, and capital gains are far more nuanced than a standard self-assessment return suggests. At Edward Harris Accountants, your trusted partner for property businesses in Oldham, we work with landlords and property investors every day, and the complexity rarely gets simpler the more properties you hold.

This is not a post designed to frighten you. It is an honest look at why property businesses benefit from specialist accounting support, what has changed in recent years, and what a good accountant should actually be doing for you — proactively, year-round, not just at tax return time.

We will cover the most common pressure points: Section 24, Making Tax Digital, the question of incorporation, and what separates a specialist property accountant from a generalist who handles the odd landlord client.

One of the most significant changes to property taxation in recent memory is Section 24 — the restriction on mortgage interest relief for individual landlords. Before 2017, landlords could deduct their full mortgage interest costs from rental income before calculating their tax bill. That relief has since been replaced by a basic-rate tax credit, which means higher and additional-rate taxpayers can find themselves paying tax on income they have not actually received in cash.

We still meet landlords who are unaware of this, or who understand the headline but have not stress-tested what it means for their specific portfolio as interest rates fluctuate. The calculation is not complicated once you know it, but the interaction with personal allowances, pension contributions, and child benefit thresholds can produce surprises.

Beyond Section 24, there are allowable expenses that landlords routinely under-claim or misclassify. The distinction between a repair (revenue expenditure, deductible immediately) and an improvement (capital expenditure, relieved differently) is one that HMRC scrutinises. The HMRC Property Income Manual sets out the framework, but applying it to a real portfolio of mixed-age properties takes experience.

Getting these things right from the outset — rather than untangling them at the point of a compliance review — is exactly the kind of proactive work a good property accountant should be doing.

From April 2026, Making Tax Digital for Income Tax (MTD for ITSA) became mandatory for landlords and self-employed individuals whose gross income exceeded £50,000 in the 2024/25 tax year. The threshold drops further in subsequent years, drawing more landlords into the regime.

Under MTD, quarterly digital updates must be submitted to HMRC using compatible software, with a final declaration at the year end. For landlords who were managing their rental accounts on a spreadsheet or handing their bank statements to an accountant once a year, this represents a significant shift in how records are kept and reported.

In practice, MTD tends to be more administratively demanding than most landlords anticipate — particularly those with multiple properties, mixed residential and commercial holdings, or properties held in joint names. The potential for errors is real, especially when rental income is seasonal or when significant maintenance expenditure falls within a quarter and creates an unusual picture.

We help our property clients set up the right cloud accounting tools, categorise income and expenses correctly from day one, and submit quarterly updates without the process becoming a burden. The goal is to make compliance feel routine rather than stressful, and to use the quarterly data to flag tax planning opportunities as they arise — not just at the end of the year.

There is a meaningful difference between a generalist accountant who handles a landlord client or two each year and an accountant who works with property businesses regularly. The specialist will know the rules around furnished holiday lettings, the nuances of HMO licensing and its accounting implications, and when incorporation might — or might not — be worth considering.

Incorporation: not always the answer

The question of whether to move a property portfolio into a limited company is one we get asked frequently. There are genuine scenarios where a corporate structure reduces the overall tax burden, particularly for higher-rate taxpayers building a long-term portfolio. But incorporation relief is not automatic, the Stamp Duty Land Tax exposure on transfer can be significant, and the ongoing compliance costs of running a company are real.

Our view is that incorporation deserves a proper analysis rather than a default recommendation either way. We model the numbers for each client’s situation — current income, mortgage position, planned trajectory — before forming a view.

Year-round support, not year-end fire-fighting

A good property accountant is not just filing your self-assessment return. They are flagging when a rent increase might push you into a higher tax band, reviewing your allowable expense claims before you submit, and keeping an eye on capital gains exposure as the portfolio evolves. That is the kind of proactive support that prevents unexpected tax bills rather than just explaining them after the fact.

There is a practical argument for working with an accountant who understands the local property market. Oldham and the surrounding Greater Manchester area has its own dynamics — the mix of older terraced stock, strong HMO demand in certain areas, and a residential market that behaves differently to other parts of the country. An accountant who works regularly with Oldham-based landlords will have seen the scenarios you are likely to face.

That said, we work with property investors across the UK, and the technical tax work is the same wherever the properties sit. What local presence does offer is accessibility — the ability to sit down and talk through a decision properly, whether you are refinancing, considering a new acquisition, or thinking about passing assets to the next generation.

At Edward Harris, we are based at Prospect House in Oldham and we make a point of being genuinely reachable. Clients contact us by phone, email, or WhatsApp for day-to-day queries. Initial conversations are free and without pressure — because most people want to talk through their situation before they commit to anything, and that is entirely reasonable.

Property businesses do not need an accountant who processes paperwork once a year. They need a partner who understands the sector, keeps up with the changing rules, and brings that knowledge to bear proactively throughout the year. That is what we aim to be for every property client we work with.
