Online accountants vs the high street
A high-street accountant in South East typically bills by the hour, meets by appointment and prices each extra question. 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 Chinnor at fees a walk-in office can't match.
There's no office to fund in Chinnor 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.
Corporation Tax in Chinnor: from first message to filed
A WhatsApp message from Chinnor is enough to start: what you need, what shape your records are in, any deadline you're worried about.
The quote arrives in writing, covers everything discussed, and is the number you'll actually pay. No revisions later.
Identity checks, engagement letter, secure record upload — all handled from wherever you are in Chinnor. We chase whatever's missing.
Nothing is filed until you've seen and approved it. Once you have, submission is electronic and confirmation comes straight back.
The same service in Chinnor as anywhere — by design
Whether your business trades from Chinnor itself or you simply live there and work everywhere, the tax rules are national — and so are we. Chinnor 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.

Chinnor 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 Chinnor?
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 Chinnor or anywhere else in South East.
I searched "corporation tax near me" — is this service really local to Chinnor?
Chinnor 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 Chinnor 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 notes our Chinnor clients ask about most
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.
Changing accountant mid-year is routine: you authorise the new firm, we write a professional clearance letter to the old one, records transfer, and HMRC authorisation moves online. Clients are usually surprised the whole thing needs almost nothing from them.
Rental profits need reporting once they're more than trivial, and the rules differ for furnished holiday lets, rent-a-room and ordinary lets. Landlords are also in the first wave of Making Tax Digital — property income counts towards the £50,000 threshold.
The first tax bill is the hardest because it can arrive with payments on account attached — up to 150% of the year's tax in one go. New businesses that save a quarter to a third of profits from day one never feel it.
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.
If a return is late because HMRC asked for one you don't actually need, it can sometimes be withdrawn entirely — penalties included. And where there's a genuine reasonable excuse, appeals succeed more often than people expect. The wrong move is ignoring the letters.
HMRC receives data directly from online platforms about sellers' income. If a side hustle has grown past the £1,000 trading allowance, coming forward first is always cheaper than being written to — penalties scale with how the disclosure starts.
Online Self Assessment returns are due by 31 January, along with any balancing payment — and HMRC's £100 penalty applies the moment the deadline passes, even if you owe nothing. Most Chinnor clients who come to us in January still file on time; the records just need to arrive before the last week.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Chinnor, message us and we'll answer against your actual numbers.
