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. Our model inverts that: the fee is fixed and written down before work begins, questions are part of the service rather than billable events, and everything happens online — the reason Polygon pays the same as everywhere else.
There's no office to fund in Polygon 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.

You review everything first. Then it goes to HMRC electronically and you get confirmation immediately.
The same service in Polygon as anywhere — by design
We built this service so that someone in Polygon never pays a premium — or accepts worse service — because of geography. Same specialists, same published fees, same speed, wherever in South East you are.
Smaller towns like Polygon are exactly why we work online: the nearest high-street firm may be a drive away, keep office hours, and price like scarcity. Your accountant should be as close as your phone — and priced like competition exists.

Polygon corporation tax FAQs
What rate of corporation tax will my company pay?
19% on profits up to £50,000, 25% above £250,000, and marginal relief in between — an effective rate that climbs gradually. Associated companies split those thresholds, which catches many owners with more than one company. We calculate it precisely.
The payment is due before the return — is that right?
Yes, oddly: payment is due 9 months and 1 day after year end, but the return itself isn't due until 12 months. We prepare everything well before the payment date so you know the bill with time to plan.
Can you review whether I've missed reliefs in past years?
Yes — you can generally amend a CT600 up to 12 months after its filing deadline, and some claims reach back further. If you think allowances went unclaimed, we'll review and quote a fixed fee for any amendment worth making.
Do I need to visit an office in Polygon?
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 Polygon or anywhere else in South East.
I searched "corporation tax near me" — is this service really local to Polygon?
Polygon 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 Polygon 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 corporation tax?
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.
Tax, briefly — the parts that affect Polygon
The capital gains annual exempt amount has shrunk to £3,000, which pulls far more ordinary disposals — shares, crypto, second properties — into reporting territory. Gains that once fell under the allowance now need a return, even when the tax due is modest.
First-year traders around Polygon tend to make the same three mistakes: registering late, mixing business and personal spending in one account, and saving nothing for the first tax bill. All three are avoidable in an afternoon of setup.
Every year a wave of returns gets filed in the final days of January. It works, but it's the most expensive way to do it: no time to check for missed reliefs, and any tax due lands as one surprise. Sending your records early — even unsorted — is the single best gift you can give your January self.
CIS deduction statements go missing constantly — contractors change, emails vanish. HMRC's records can fill some gaps, but the fastest refunds belong to subcontractors who keep every monthly statement. If you're in construction around Polygon, that one habit is worth real money.
Can't pay the bill by the deadline? File anyway. Filing and payment are penalised separately, and HMRC's Time to Pay arrangements can spread the bill — but only once the return is in. Not filing because you can't pay turns one problem into two.
The first hire brings PAYE registration, Real Time Information submissions every payday, workplace pension auto-enrolment and payslips that must be right. It's all completely manageable — as a monthly routine run by software, not a monthly crisis.
A limited company juggles two regulators: Companies House wants accounts within nine months of year end, HMRC wants corporation tax paid at nine months and a day. Same starting point, different documents — and late filing penalties at Companies House escalate automatically and are rarely cancelled.
MTD for Income Tax starts with the £50,000+ income group in April 2026, with lower bands following. Quarterly digital updates sound worse than they are — with software doing the bookkeeping, the quarters largely take care of themselves.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Polygon, message us and we'll answer against your actual numbers.
