What makes us different

Online accountants vs the high street

Traditional firms around South East still run on hourly billing, office appointments and fees you discover after the work. We work the other way round: one fixed fee agreed in writing before anything starts, every question included, and the whole engagement handled online — which is exactly why we can serve Portsmouth at fees a walk-in office can't match.

There's no office to fund in Portsmouth and no office to visit: records travel through our secure portal or WhatsApp, approvals happen on your phone, and filings go to HMRC and Companies House electronically. You get the same qualified work — minus the overheads, the travel and the surprises on the invoice.

Serving Portsmouth

The same service in Portsmouth as anywhere — by design

Whether your business trades from Portsmouth itself or you simply live there and work everywhere, the tax rules are national — and so are we. Portsmouth clients get the same preparers, the same fixed fees and the same deadline tracking as every other town on this site.

A lot of our South East clients switched from local firms after one too many surprise invoices. The fix wasn't a cheaper local firm; it was removing the billing model that produces surprises. Fixed fees, in writing, before the work — that's the whole trick.

Questions

Portsmouth cis tax returns FAQs

How much CIS refund am I owed?

Most subcontractors have 20% deducted at source all year — usually more than their final tax bill once expenses and the personal allowance are counted. Refunds of £1,500–£3,000 are common, claimed through your Self Assessment.

How quickly will my refund arrive?

Once the return is filed, HMRC typically pays CIS refunds within 2–6 weeks. We file promptly after 6 April so the claim is in the queue as early as possible.

What is gross payment status?

It lets contractors pay you without CIS deductions — better cash flow. You need to pass HMRC's turnover and compliance tests; we assess whether you qualify and handle the application.

Do I need to visit an office in Portsmouth?

No — there's nothing to visit and nothing to print. We're an online firm: records go through our secure portal or WhatsApp, and everything is filed electronically. It works the same whether you're in Portsmouth or anywhere else in South East.

I searched "cis near me" — is this service really local to Portsmouth?

Portsmouth is fully covered, yes. The work is done online, which in practice means more local than an office: same-day replies instead of appointment slots, and the same published fixed fee whether you're in Portsmouth town centre or the edge of South East. If you'd rather talk it through first, WhatsApp us — a real person answers.

Who will actually handle my cis?

Bohzo Accountants — a trading name of Bohzo Ltd, a registered UK company (No. 15031604). You get a named contact, a fixed fee in writing, and nothing is filed until you've reviewed and approved it.

How do your fixed fees work?

You tell us your situation, we quote one fixed price in writing before any work starts, and that price never changes mid-job. If your case is unusually complex we'll say so up front and agree a different fixed price — but the fee is always agreed before we begin, never after.

Worth knowing

Things worth knowing before your next filing

Payroll and pensions for small employers

Directors paying themselves a salary still need a PAYE scheme and RTI submissions, even in a one-person company. It's a five-minute monthly task with software — and a recurring penalty generator without it.

Crypto is taxable — and visible

Disposing of crypto — selling, swapping one coin for another, spending it — is a capital gains event, and staking or mining income is usually income. Exchanges share data with HMRC, so the tax position exists whether or not it's been calculated.

When HMRC writes to you

Scam "HMRC" messages outnumber real ones — HMRC doesn't demand payment by gift card or threaten arrest by text. Real letters have reference numbers that we can verify directly with HMRC before anyone responds.

CIS: refunds hide in the paperwork

Subcontractors under the Construction Industry Scheme have 20% deducted at source — often more than their final tax bill once expenses and the personal allowance are counted. That's why CIS refunds are so common: the average claim is well into four figures, but only if the deduction statements are all gathered.

Making Tax Digital is coming for income tax

From April 2026, self-employed people and landlords with qualifying income over £50,000 move onto Making Tax Digital for Income Tax: digital records and quarterly updates to HMRC, not one annual return. The year before is the right time to get bookkeeping into shape.

Capital gains: windows and allowances

Timing disposals across tax years, using losses properly, and the spousal transfer rules can all legitimately reduce capital gains bills — but only before the sale. CGT planning after completion is just arithmetic.

Payments on account, decoded

Payments on account catch people out because the first year effectively bills you one-and-a-half years of tax at once. Knowing that in advance changes how you save through the year — and if profits fall, we can apply to reduce the July payment rather than lending HMRC money interest-free.

Sole trader or limited company?

Incorporation isn't a milestone, it's a calculation: corporation tax versus income tax and NICs, dividend taxation, what you need to draw versus what can stay in the company, and whether limited liability matters for your work. For some Portsmouth businesses it saves thousands; for others it's pure extra paperwork.
