Online accountants vs the high street
Most local firms near March 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 March at fees a walk-in office can't match.
There's no office to fund in March 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 March: from first message to filed
A WhatsApp message from March 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 March. 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 March as anywhere — by design
We built this service so that someone in March never pays a premium — or accepts worse service — because of geography. Same specialists, same published fees, same speed, wherever in East of England you are.
A lot of our East of England 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.

March 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 March?
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 March or anywhere else in East of England.
I searched "corporation tax near me" — is this service really local to March?
March 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 March 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.
From our inbox: what March businesses ask us
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.
Since Section 24, individual landlords can't deduct mortgage interest as an expense — it's a 20% tax credit instead, which pushes some higher-rate landlords into surprising bills. Whether to hold property personally or through a company is now a genuine question with genuine trade-offs.
Miss 31 January and the £100 fine is automatic; three months later daily penalties start. If you're behind on a return, the maths almost always favours filing quickly over waiting — penalties grow on a timetable, and HMRC charges interest either way.
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.
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.
VAT registration becomes compulsory once your taxable turnover in any rolling 12 months passes £90,000 — and "rolling" is the word that catches people, because it's not your accounting year. Businesses in March growing towards that line should be watching it monthly.
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.
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.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in March, message us and we'll answer against your actual numbers.
