Not entirely sure where you stand with rental tax?
Landlords often fall into a pattern of catching up rather than planning ahead. The rules around allowable expenses, mortgage interest relief, and what triggers a capital gains liability change with some regularity, and most people managing a property alongside a job or business have neither the time nor the inclination to stay on top of it. The Self Assessment deadline arrives, the paperwork gets scrambled together, and the tax bill lands as a surprise.
- Claiming rental expenses by guesswork rather than a clear, consistent method
- Self Assessment completed in a rush each January with incomplete rental records
- No advance visibility of the CGT position before a property sale completes
What a well-run landlord tax position looks like
Allowable expenses properly identified and recorded. Tax obligations calculated well before deadlines. Planning conversations that happen before decisions, not after. That is the difference between a reactive tax return and an accountant who understands property.
- Rental expenses identified, categorised, and claimed correctly every year
- Records maintained throughout the year so January is not a scramble
- CGT position modelled before you decide to sell, so the number is not a shock
- Fixed-fee pricing agreed upfront, no hourly billing for additional questions

What the landlord accounting service covers
A fixed-fee service covering the compliance obligations most landlords carry, with planning support built in rather than bolted on as an afterthought.
Self Assessment and Rental Income Tax
Your SA100 prepared and filed with rental income correctly reported and every allowable expense claimed. Finance costs, repairs, letting agent fees, professional charges — each assessed against HMRC’s current rules so nothing is left on the table or incorrectly claimed.
Included as standardProperty Tax Planning and CGT
Capital gains tax calculated before a disposal, not on the morning of completion. Section 24 mortgage interest restriction reviewed annually so you understand the effective tax rate on your portfolio. Inheritance tax implications can be considered where the portfolio warrants it.
Advisory servicePortfolio Bookkeeping and Cloud Records
Monthly or quarterly bookkeeping for your rental income and expenditure, maintained in Xero or QuickBooks Online. Clean records throughout the year mean your year-end return is straightforward and your position is visible at any point, not just in January.

What makes this different from a general accountant
Any accountant can file a Self Assessment. These are the things that distinguish a landlord-focused service from a generalist one.
Property tax knowledge applied from day one
Supreme Consulting has worked with landlords and property investors since 2005. The rules around Section 24, principal private residence relief, furnished holiday lets, and HMO structures are not things we look up — they are part of the day-to-day work. You will not need to spend the first twenty minutes of every call explaining how your portfolio is structured.
Planning that happens before decisions
Tax advice delivered after a transaction completes is considerably less useful than advice given before. The planning conversations here happen proactively — before a purchase, before a sale, before a change in ownership structure. That means fewer surprises and a better overall tax position over time.
Fixed fees, agreed before we start
Every engagement is scoped and priced upfront. No hourly billing, no invoice at the end of the year that bears no relation to what you expected to pay. If the scope changes, that conversation happens before the work does.
Up and running in four straightforward steps
The process is designed to involve as little effort from you as possible while we handle the transition.
A short discovery call
A no-obligation conversation to understand your portfolio, your current tax setup, and what you actually need from an accountant. No preparation required on your part. You will leave the call with a clear picture of what comes next.
A fixed-fee proposal
You receive a written proposal covering the scope of services, what is included, and the monthly or annual fee. No ambiguity about what you are paying for and no hidden extras for standard questions during the year.
Onboarding and records migration
We handle the switch from your previous accountant or spreadsheet setup. Rental income records are moved to the cloud, integrations are set up, and any catch-up work is scoped and priced separately if needed. The aim is a clean starting point.
Your tax position, visible year-round
From this point forward, your records are current, your obligations are monitored, and tax planning conversations happen before deadlines rather than in response to them. January is no longer something to dread.
“I’m so grateful for the help received with my small cleaning business. Stuart holds your hand and advises throughout!”
Things landlords usually ask before signing up
Do you understand the Section 24 mortgage interest restriction and how it affects my tax bill?
Yes. Section 24 phased out the ability to deduct mortgage interest as a business expense for individual landlords and replaced it with a 20% tax credit. For higher-rate taxpayers in particular, the impact on effective tax rates has been substantial. We review this as part of every landlord engagement, model the real-world impact on your position, and where ownership structure changes might be worth considering, we say so plainly rather than leaving it as a vague suggestion.
What does the landlord accounting service cost?
Pricing depends on the number of properties, whether you hold them personally or through a limited company, and what services you need beyond the Self Assessment return itself. A single-property landlord with straightforward rental income will pay considerably less than someone managing a portfolio with multiple tenancies, mixed structures, and quarterly bookkeeping. All fees are fixed and agreed in writing before we start. A free quote takes one working day.
My records are in a bit of a state — is that a problem?
It is not unusual. Landlords who have managed their own records for a few years, or who have moved between accountants, often arrive with gaps and inconsistencies. We assess what is there, scope any catch-up work separately, and price it transparently. The goal is a clean starting point — after that, maintaining order is considerably simpler than creating it from scratch.
Is there a minimum contract or lock-in period?
No. There is no minimum term. If after a few months it is not working for you, you give notice and we transfer your records cleanly with nothing outstanding. In practice most clients stay because the service is straightforward and the fee is predictable, but that is a choice, not an obligation.
Can you help with the tax position on a furnished holiday let or Airbnb property?
Yes. Furnished holiday lets have historically attracted different tax treatment to standard residential lets, including more favourable capital allowances and CGT treatment. Recent changes to the FHL regime have affected this, and the position is worth reviewing carefully before drawing any conclusions. We work with holiday let owners and short-term rental hosts and can advise on the current rules and what they mean for your specific situation.
When should I be thinking about capital gains tax on a property I plan to sell?
As early as possible, ideally before you accept an offer. CGT on residential property disposals is due within 60 days of completion, which catches many people out. The rate, the available reliefs — including principal private residence relief where applicable — and the impact on your income tax position for the year can all be modelled in advance. Knowing the number before you commit to a sale price is considerably more useful than finding out the morning contracts exchange.
