Accountant in Portsmouth

Tax & Accounting for Portsmouth Businesses

Portsmouth is a busy waterfront city with a strong naval, marine, defence, retail and creative economy across Gunwharf Quays, Southsea and the city centre. We act for Portsmouth sole traders, CIS subcontractors, landlords and limited companies, claiming every allowable expense and keeping you fully compliant at a fixed monthly fee. Portsmouth (PO1 & PO2) supports a diverse base of sole traders, CIS construction trades, self-employed drivers, landlords and limited-company directors, and each needs something slightly different from an accountant.

That gives Portsmouth a particular accounting profile: the engineering and manufacturing firms that Portsmouth is known for need stock, plant and capital-allowances-aware bookkeeping so every machine, tool and vehicle is claimed. Construction and CIS trades need monthly returns or an annual refund claim; self-employed drivers and trades need vehicle, tools and mileage captured; limited companies need a tax-efficient salary and dividend split; and the local landlord market needs Section 24 mortgage-interest planning and Making Tax Digital readiness. We work with Portsmouth clients entirely online at fixed monthly fees, and as an HMRC-registered agent we deal directly with HMRC on your behalf, so you never spend hours on hold or navigate their website yourself.

💡 As an HMRC-registered agent, we deal with HMRC directly on your behalf, file your returns and keep you compliant, so you can get on with running your business.

Real Client Story

How we cut a Portsmouth business tax bill by £5,500

When a Southsea marine-trades business came to us they were filing their own returns and missing a string of allowable costs, from equipment and software to home-office, travel and professional fees. They were also on the wrong VAT scheme and had never had their salary and dividend mix reviewed.

We rebuilt their bookkeeping on cloud software, claimed every legitimate expense, moved them onto the right VAT scheme and set a tax-efficient salary and dividend split. The result was a tax saving of £5,500 in the first year, with a clear fixed monthly fee and no more last-minute filing panic.
