Portsmouth is the UK’s only island city — a place whose entire identity has been shaped by the sea, the Royal Navy, and the people who serve both. HMNB Portsmouth is the largest Royal Navy base in the UK. The Historic Dockyard draws over 500,000 visitors a year. Gunwharf Quays is one of England’s most successful waterfront retail and leisure destinations. And the University of Portsmouth’s 30,000 students create one of Hampshire’s most active rental and services economies. Hayes brings ACCA-qualified accounting to every corner of Portsmouth’s economy — from naval contractors and tourism businesses to the city’s large self-employed and SME community — at fixed fees that make real sense.
Hayes serves Portsmouth, Fareham, Gosport, Havant, and all of South Hampshire. Self-assessment from £150+VAT. Limited company packages from £75/month. Naval contractor IR35, tourism VAT, student landlord tax, and all 18 Hayes services. Free consultation always.
Portsmouth’s Economy — Key Tax Sectors
HAYES CHARTERED CERTIFIED ACCOUNTANTS IN PORTSMOUTH AND TAX CONSULTANTS
Many contractors working at HMNB Portsmouth or on Royal Navy programmes through the defence supply chain choose to operate through a personal service company (PSC) — but IR35 has changed how this works significantly. Since April 2021, large and medium-sized clients in the defence sector determine IR35 status rather than the contractor. If your role is assessed as inside IR35, operating through a limited company provides little tax advantage, and an umbrella company arrangement may actually be simpler. If it’s genuinely outside IR35, a limited company saves you significant National Insurance. Hayes reviews your specific contract and working arrangement, gives you an honest written assessment, and sets up whichever structure makes most financial sense for your actual situation.
People Also Ask — Portsmouth Tax

Yes — serving military personnel can claim flat rate expenses for uniform maintenance through HMRC’s flat rate expense allowance.
Do Gunwharf Quays retail businesses pay different VAT rates?
Standard VAT rules apply, but the mix of retail and hospitality tenants means VAT scheme selection is important for most Gunwharf businesses.

Hayes Chartered Certified Accountants in Portsmouth and Tax ConsuLtants offers self-assessment from £150+VAT and limited company packages from £75/month — fixed fees, no surprises.
Do Portsmouth student landlords need to worry about Section 24?
Yes — with 30,000 University of Portsmouth students, HMO demand is high and Section 24 affects most higher-rate landlords.
Can Portsmouth ferry company workers claim expenses?
Yes — cross-channel ferry crew may qualify for Seafarers’ Earnings Deduction if they spend 50%+ of the year outside UK waters.
Accountants & Tax Advisors in Portsmouth, Hampshire
Portsmouth’s economy is unlike any other city in the South of England — and its tax complexity reflects that. HMNB Portsmouth is the UK’s largest naval base, employing directly and indirectly tens of thousands of people across Royal Navy operations, civilian MOD roles, and the enormous contractor and supply chain community that supports naval programme delivery. BAE Systems’ surface ship business has its centre here. QinetiQ, Babcock, and Thales all have significant Portsmouth presences. The procurement, engineering, and programme management work that flows out of the base creates a substantial professional contractor workforce, many of them working through limited companies and navigating IR35 in a large-employer defence context.
Beyond defence, Portsmouth’s economy has transformed its public face over the last two decades. Gunwharf Quays — built on the former HMS Vernon torpedo school site — is now one of England’s most successful waterfront retail, restaurant, and leisure destinations, anchored by the Spinnaker Tower and drawing huge visitor numbers. The Historic Dockyard brings over 500,000 visitors annually to see HMS Victory, HMS Warrior, and the Mary Rose. This tourism and retail economy supports hundreds of small businesses in hospitality, food and drink, retail, and leisure — all with their own accounting and VAT needs.
The University of Portsmouth’s 30,000-strong student population creates intense HMO demand in Southsea, Milton, and Fratton — postcodes where buy-to-let landlord portfolios are common and the tax implications of Section 24 are live for most higher-rate taxpayers. Add a large self-employed trades community supporting Portsmouth’s active housing renovation market, and you have an economy that needs genuine accounting expertise across a wide range of areas. Hayes provides exactly that, remotely, at fixed fees that don’t penalise you for being on Portsea Island.
Portsmouth Tax Advisors
Portsmouth-Specific Tax Expertise
The HMNB Portsmouth and Gosport defence cluster — including BAE Systems, QinetiQ, Babcock, and Thales — employs a large contractor workforce in naval engineering, ship systems integration, programme management, and defence electronics. Since April 2021, these large clients determine IR35 status rather than the contractor. Many defence engineering roles are assessed as inside IR35 because of integration, control, and the long-term nature of the engagement. We review your Status Determination Statement against your actual working arrangement, challenge incorrectly determined assessments where appropriate, and advise on your most tax-efficient structure given the outcome.
Gunwharf Quays and the wider Portsmouth waterfront economy — including the Historic Dockyard, Spinnaker Tower, and the Old Portsmouth hospitality cluster — generate substantial retail and hospitality turnover with genuine VAT complexity. Mixed retail and food businesses need careful VAT scheme selection. Tourism and admission-based businesses like the Historic Dockyard have specific VAT treatment on entrance fees, gift shop sales, and catering. We serve Portsmouth’s tourism and retail businesses with VAT registration, scheme selection (flat rate, standard, or retail schemes), quarterly returns, and MTD compliance — all at fixed monthly prices.
The University of Portsmouth’s 30,000 students create one of Hampshire’s most active HMO markets — concentrated in Southsea, Milton, and Fratton. For landlords with mortgaged buy-to-let properties, Section 24 has materially increased tax bills since full implementation. The question of whether to incorporate your Portsmouth portfolio into a limited company depends on your specific mortgage position, income level, and long-term plans — there’s no universal right answer. We model your exact numbers, including the SDLT and CGT costs of transfer, and tell you honestly whether incorporation makes financial sense for your situation.
Portsmouth International Port is one of the UK’s busiest ferry terminals — Brittany Ferries, DFDS, and Condor Ferries all operate regular cross-channel services from here. Crew working on these vessels may qualify for the Seafarers’ Earnings Deduction if they meet the qualifying conditions — specifically, spending at least 50% of the 365-day qualifying period working on a ship outside UK territorial waters. For a cross-channel route, this depends on the frequency and duration of crossings, the specific vessel, and the individual’s time-at-sea calendar. We assess each Portsmouth ferry crew member’s position individually and claim SED where it applies.
Portsmouth has a large and active self-employed tradespeople community — builders, electricians, plumbers, plasterers, and decorators — working across the city’s residential renovation market and on commercial projects throughout South Hampshire. CIS subcontractors have tax deducted at source by contractors and are frequently owed significant refunds at year end when legitimate expenses are claimed. We file CIS annual returns, claim back overpaid deductions, and help Portsmouth tradespeople set up simple record-keeping systems that make the whole process painless year on year.
Portsmouth’s large serving military and civilian MOD community has specific tax considerations that many generalist accountants don’t know well. Serving Royal Navy personnel can claim flat rate expenses for uniform maintenance, overseas allowances may be partially tax-exempt, and those transitioning to civilian employment or setting up businesses after leaving service face a distinct set of tax planning considerations. We advise Portsmouth’s serving and veteran military community on their personal tax position, expense claims, transition planning, and business setup — and we understand the Armed Forces Pension Scheme’s interaction with self-employment income.

Real Questions from Portsmouth Clients
Not necessarily — and it’s worth checking. Since April 2021, the end client (in this case, the MOD or a large defence prime like BAE Systems or QinetiQ) is responsible for issuing a Status Determination Statement (SDS) that sets out their assessment and the reasoning behind it. You have the right to formally disagree with the determination if you believe it’s wrong. The IR35 status tests focus on substitution (can you send someone else to do the work?), control (does the client control how, when, and where you work, or do you have genuine autonomy?), and mutuality of obligation (is there an expectation of ongoing work being offered and accepted?). Long-term embedded defence roles often score as inside IR35 on these tests — but not always. We review the SDS against your actual working arrangement and tell you honestly whether the assessment looks correct. If it doesn’t, we advise on the right way to challenge it.
Serving Royal Navy personnel can claim a Flat Rate Expense (FRE) allowance for the upkeep of uniform and protective clothing — for most ratings and officers, this is £100 per year and is applied automatically through your tax code, though some personnel have never had it applied correctly. If you use tools or specialist equipment that you purchased yourself for work, you may be able to claim the cost above the standard FRE. Overseas allowances — including operational allowances paid during qualifying overseas deployments — are exempt from income tax under the Armed Forces operational tax relief provisions. If you have additional income from property rental, investments, or side work, you’ll need to register for self-assessment and declare it. We review the complete tax position for Portsmouth’s serving personnel and make sure everything is set up correctly.
Restaurant VAT is one of the most commonly mishandled areas of UK tax, and the Gunwharf Quays and Waterfront restaurant cluster has a particularly complex mix of eat-in, takeaway, and event catering. Hot food and eat-in food (at any temperature) is standard-rated at 20%. Cold food sold as takeaway is generally zero-rated — but not hot drinks, which are always standard-rated, and not food sold alongside a standard-rated service. Alcoholic drinks are always standard-rated. The practical challenge is that most restaurant tills aren’t set up to split these categories correctly from day one, and many restaurant operators are paying more VAT than they need to (or less, creating a future liability). We set up Portsmouth restaurant clients on the right VAT scheme and ensure the VAT accounting reflects what’s actually happening at the till.

Every fee is agreed before we start work. There are no hourly rates, no chargeable phone calls, and no end-of-year additions. The free initial consultation helps us understand exactly what you need so we can give you a precise quote with no obligation.
With four mortgaged HMOs in the Southsea student rental market, Section 24 is likely to be affecting your tax bill significantly — especially if you’re a higher-rate taxpayer. Before Section 24, you could deduct your mortgage interest from rental income before calculating tax. Now you get a 20% tax credit on the interest instead. For a 40% taxpayer, this effectively means you’re paying 20p of income tax on every £1 of mortgage interest you pay — a real and substantial cost. Across four Southsea HMOs, depending on your mortgage balances and rental income, this could be adding thousands to your annual tax bill compared to pre-2017. Whether moving your portfolio into a limited company makes sense involves modelling the CGT on transfer (if properties have risen in value), the SDLT on re-purchase, the mortgage availability and rate differential for company mortgages, and your long-term plan for the properties. We do this modelling honestly — and sometimes the answer is that incorporation doesn’t make economic sense, in which case we say so.
What Portsmouth Clients Say
“I’ve been contracting at the base for six years. My agency told me I was inside IR35 and I just accepted it. Hayes actually read my contract, looked at how I actually work, and confirmed the SDS was incorrect. Challenged it properly — saved me over £8,000 last year alone.”
Mark T.Naval Systems Contractor, HMNB Portsmouth“I run a restaurant on Gunwharf and had never had my VAT set up properly. Hayes sorted the scheme, found we’d been overclaiming on some lines and underclaiming on others, and got everything on a clean footing. Much better peace of mind going forward.”
Fatima A.Restaurant Owner, Gunwharf Quays, Portsmouth“Four HMOs in Southsea and my previous accountant had never mentioned Section 24 once. Hayes ran the numbers properly, showed me exactly what I was overpaying, and set me up with a plan. Haven’t incorporated yet — they said it wasn’t the right call for my situation — but I’m finally managing it correctly.”
