The team you speak to first is the team that works on your portfolio, all working together. You won't be passed between departments, and you won't have to explain your portfolio twice.
We model what each option means for your tax bill, your mortgages and your family's plans before recommending anything. Sometimes the answer is to change nothing.
After a free first call, we confirm the scope and the fee in writing. No hourly billing and no surprises.
Landlords with growing portfolios face some of the most complicated tax decisions any individual makes. Section 24 changed the economics of borrowing. Stamp duty surcharges changed the cost of buying. And the choice between personal ownership and a company, or how to pass property to the next generation, can shape a family's finances for decades.
ASWATAX found that portfolio landlords were a growing share of its work, and that many struggled to find advice focused on them. So we set up Property Tax Advisory as a specialist property practice within the firm.
Over 15+ years, our team has advised 100+ landlords and portfolios and helped incorporate £100m+ of property, in portfolios up to £30m.
We advise individual landlords, couples, families and property companies across the UK, and the brokers, letting agents and accountants who work with them.
Property Tax Advisory sits alongside ASWATAX's other specialist services, so you can get joined-up advice if your affairs go beyond property:
Qualifications
Every plan is reviewed by a Chartered Tax Adviser (CTA). The team is Big 4-trained, and includes Chartered Accountants qualified with the ICAEW and the ACCA.

FAQs
Property Tax Advisory is the specialist property practice of ASWATAX, a UK tax advisory firm. It's a service of ASWATAX LTD, a company registered in England and Wales. Advice comes from a Big 4-trained team that includes ICAEW and ACCA Chartered Accountants, with every plan reviewed by a Chartered Tax Adviser. We set it up to give portfolio landlords a team that focuses on property tax and nothing else.
It's part of ASWATAX. ASWATAX advises owner-managed businesses and their owners on a wide range of tax matters, and Property Tax Advisory is the part of the firm that works only with landlords and property investors. You get a specialist team for your portfolio, backed by the wider firm when your affairs also involve a trading business, a sale or a family company.
Our team has more than 15 years' experience and has advised 100+ landlords and portfolios. We have helped incorporate more than £100m of property, and we've worked with portfolios up to £30m. That covers individual landlords, couples, families who own property together and existing property companies looking at their next step.
Landlords with three or more properties and growing portfolios. That includes individuals and couples, families and property partnerships, landlords who already use a limited company, and UK property owners who live abroad. We also work with the mortgage brokers, letting agents and accountants who look after them. We're not set up for first-time or accidental landlords with a single let.
We advise on Section 24 and how mortgage interest is taxed, whether and how to incorporate a portfolio, running and taking money out of a property company, capital gains tax when you sell, stamp duty land tax when you buy, inheritance tax and passing property to children, Family Investment Companies and the non-resident landlord rules. We focus on planning and structure, not routine bookkeeping.
Not as our main service. Property Tax Advisory focuses on advice and structuring: the decisions that change how much tax a portfolio pays over many years. Many clients keep their existing accountant for annual returns and accounts, and we work alongside them. If you need help with a specific return, such as a 60-day capital gains return after a sale, ask us.
Property tax has rules of its own that rarely come up elsewhere: Section 24, the stamp duty surcharges, incorporation relief and its business test, ATED, and the way inheritance tax treats let property. Decisions such as incorporating a portfolio are hard to reverse and expensive to get wrong. Many accountants handle the annual work well and bring in a specialist for these one-off decisions.
Every plan is reviewed by a Chartered Tax Adviser (CTA), the senior professional qualification of the Chartered Institute of Taxation. The team is Big 4-trained and includes Chartered Accountants qualified with the ICAEW and the ACCA. That combination matters for landlords, because good property tax advice needs both technical tax knowledge and a clear grasp of the numbers.
Yes, and we prefer to. Incorporating or restructuring a portfolio usually needs a broker to arrange company lending, a conveyancer to handle any transfers and an accountant to keep the books afterwards. We design the tax side, agree the order of steps with everyone and make sure each adviser knows what they need to do and when.
ASWATAX runs a small number of specialist services. Demerger Tax (demergertax.co.uk) helps owners separate property from a trading company. Holding Company (holding-company.co.uk) covers setting up a holding company. Transaction Tax Partners (transactiontaxpartners.co.uk) advises on buying and selling businesses. Our main practice is at www.aswatax.co.uk. Each focuses on one kind of work, with the same firm behind it.
Our registered office is at 124 City Road, London EC1V 2NX. We advise landlords across the UK and UK property owners who live overseas. Most of our work happens by video call, phone and email, which suits busy landlords and fits around your broker's and accountant's timetables. If a face-to-face meeting would help at a key stage, ask us.
Yes. Income tax and capital gains tax on rental property work broadly the same across the UK, although Scottish taxpayers have their own income tax rates and bands. When you buy, Scotland has land and buildings transaction tax and Wales has land transaction tax instead of SDLT, each with its own rates and surcharges. We take those differences into account.
We work on fixed fees, agreed upfront. After a free first call we confirm in writing what we'll do and the fee for it, so you know the cost before any work starts. We don't charge by the hour or add surprise extras. If the scope changes later, we agree that with you before doing the extra work.
We respond the same working day. Property decisions often have a date behind them, such as a mortgage product ending, a purchase completing or a sale agreed. Tell us the date that matters when you get in touch and we'll plan around it, from the first call through to the final filings.
Property Tax Advisory is a service of ASWATAX LTD, a limited company registered in England and Wales. ASWATAX LTD is registered with the Chartered Institute of Taxation as Chartered Tax Advisers and for the purposes of anti-money laundering legislation. As the money laundering rules require, we'll ask for identity documents before we start work.
No honest adviser can promise that before looking at the facts. Sometimes the right answer is to change your structure; sometimes it's to keep things as they are and plan the timing of sales or gifts. Our job is to show you the real numbers for each option, including any costs of making a change, and recommend what fits your plans.
