Landlord Tax Made Simple for Portsmouth Property Owners

Portsmouth has one of the south coast's most active regional buy-to-let markets, with strong rental demand across PO1, PO2, PO3, PO4 and PO5 from naval families (the Portsmouth Naval Base remains the home of the Royal Navy surface fleet), city-centre professionals, the substantial student-let trade supporting the University of Portsmouth, the Southsea family-let market, and city-centre tower BTL across the substantial Gunwharf Quays and Tipner West regeneration. Many Portsmouth landlords hold portfolios across central Portsmouth and the wider PO postcodes and face the full complexity of the modern landlord tax landscape: Section 24 mortgage interest restrictions have significantly increased tax bills for higher rate taxpayers, Making Tax Digital is now live for landlords with income over £50,000, and capital gains exposure on appreciated central Portsmouth properties is substantial. Naval-family lets (typically short-tenure as personnel rotate between postings) are a distinctive feature of the Portsmouth rental market.

Your Tax Help Accountants, HMRC-registered, handles all aspects of landlord tax for Portsmouth property owners across PO1, PO2, PO3, PO4 and PO5. Self-Assessment, Section 24 planning, MTD compliance, capital gains tax and incorporation advice, all at a fixed monthly fee with same-day filing available when it matters.

💡 As an HMRC-registered agent, we deal with HMRC directly on your behalf, filing returns, managing compliance and advising on strategies to reduce your landlord tax burden legally and permanently.

Real Client Story

How we restructured a Portsmouth portfolio landlord

Client Q owns seven rental properties across Portsmouth and Southsea, including four naval-family-let semis with short rolling tenancies, two student-let HMOs near the University of Portsmouth campus and a Gunwharf Quays apartment. When they came to us they were declaring rental income on Self-Assessment as a sole landlord, being hit hard by Section 24, juggling the very high tenant turnover typical of naval-family lets (frequent posting moves), and the additional admin of maintaining HMO licences on the student properties. Their effective tax rate on the portfolio was sitting around 39 per cent of net rental income once the disallowed mortgage interest was factored in, and they had never had a proper conversation about whether their structure suited their portfolio size.

We modelled the position of incorporating the portfolio into a Property Investment Company against keeping it personal. The incorporation had transfer costs (Capital Gains Tax on the latent gains and Stamp Duty Land Tax including the Additional Dwelling Supplement) of around £44,000 upfront. Against that, the ongoing tax saving from full mortgage interest deductibility inside the company plus Corporation Tax rates substantially lower than their higher-rate income tax was around £15,000 a year. The breakeven was just under three years.

Outcome: ongoing tax saving of around £15,000 a year going forward, a Section 24 problem that no longer exists inside the corporate structure, a substantially improved Inheritance Tax position compared with holding the portfolio personally, and a structure now ready to absorb future portfolio growth without the headwind of the mortgage interest restriction.

Landlord Tax Questions Answered

Frequently Asked Landlord Tax Questions

What rental expenses can Portsmouth landlords claim to reduce their tax bill?
Allowable expenses include letting agent fees, repairs and maintenance (not improvements), buildings and contents insurance, ground rent and service charges, accountancy fees, mortgage arrangement fees spread over the loan term, professional cleaning and gardening, council tax during void periods, advertising for tenants and reasonable travel costs to manage or inspect the property. You cannot claim the mortgage capital repayment, your own time or improvements. We review your expenses thoroughly every year to ensure every legitimate deduction is claimed.
How does Section 24 affect Portsmouth buy-to-let landlords with mortgages?
Section 24 replaced full mortgage interest deductibility with a 20 per cent basic rate tax credit. For a Portsmouth higher rate taxpayer with significant mortgage debt, this means paying 40 per cent tax on rental income that includes the mortgage interest cost, then receiving only 20 per cent back. The effective additional annual tax per £10,000 of mortgage interest for a higher rate taxpayer is £2,000. We calculate your exact position across your full portfolio and model all available strategies to mitigate this.
Do Portsmouth landlords need to comply with Making Tax Digital?
MTD for Income Tax has applied from April 2026 for landlords with income over £50,000, and from April 2027 for those over £30,000. Many Portsmouth landlords are caught by these thresholds. We handle the complete MTD setup, recommending and setting up the right cloud accounting software, connecting your bank feed, filing quarterly digital updates and preparing the annual declaration, all as part of your fixed monthly service. No technical knowledge required.
Should Portsmouth landlords incorporate their portfolio into a limited company?
For Portsmouth higher rate taxpayers with multiple mortgaged properties, incorporation can offer significant long-term tax savings. Mortgage interest remains fully deductible in a company, profits are taxed at Corporation Tax rates and retained profits can be reinvested before personal tax is triggered. However, stamp duty and CGT on transfer can be substantial. We model the transfer costs against the projected long-term savings for your specific Portsmouth portfolio and give you a clear numbers-based recommendation.
Can you advise on capital gains tax when selling Portsmouth rental properties?
Yes. Portsmouth PO1, PO2, PO3, PO4 and PO5 property values have appreciated significantly with Gunwharf Quays regeneration, meaning many landlords are sitting on very large latent capital gains. CGT on residential property is charged at 18 per cent or 24 per cent depending on your tax band, and you must report and pay within 60 days of completion. Advance planning, including timing of disposal, use of annual exemptions, spousal transfer and principal private residence relief for former homes, can make a very significant difference to your net proceeds. We work with you well before any planned sale.
I let predominantly to naval families with short tenancies. What additional expenses can I claim?
High-turnover naval-family lets generate substantial deductible expenses at each tenancy change: re-advertising costs, letting agent fees per new tenancy, end-of-tenancy cleaning, gas safety certificates issued at change of tenancy, inventory check-ins and check-outs, and any routine repairs of wear-and-tear from frequent moves. Replacement of Domestic Items relief applies to furniture, white goods and similar items as they are replaced (not the initial purchase, but like-for-like replacements after that). Void periods between tenancies are also a deductible expense for council tax. We capture every legitimate expense at year-end.
Can you take over from my current Portsmouth accountant?
Usually 7-10 working days from signature of our engagement letter. Professional clearance, HMRC agent authorisation, records transfer, software migration. No break in your filing, no double charging.
