Online accountants vs the high street
Most local firms near Onehouse quote low, bill by the hour and reserve the right to charge for every phone call. 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 Onehouse at fees a walk-in office can't match.
There's no office to fund in Onehouse 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.

Smaller towns like Onehouse 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.

Onehouse 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 Onehouse?
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 Onehouse or anywhere else in East of England.
I searched "corporation tax near me" — is this service really local to Onehouse?
Onehouse 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 Onehouse town centre or the edge of East of England. 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.
Things worth knowing before your next filing
Every tax bill is predictable months in advance — which makes tax the most plannable cost a business has. A separate tax savings account, fed a fixed percentage of every sale, converts January from a crisis into a transfer.
New companies often have a long first accounting period, which can mean two corporation tax returns for one set of accounts. It's normal, but it's exactly the kind of thing that's cheaper to get right first time than to unpick.
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.
Dividends can only be paid from accumulated profits, and paperwork matters: board minutes and dividend vouchers, dated correctly. "Illegal dividends" isn't dramatic language — overdrawn payments can be reclassified, with tax consequences, if the profits weren't there.
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.
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.
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.
HMRC requires records to be kept for at least five years after the filing deadline for the self-employed. Digital copies count. A cloud folder or app now beats a carrier bag of paper every time — for you and for any future enquiry.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Onehouse, message us and we'll answer against your actual numbers.
