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 Windsor at fees a walk-in office can't match.

You get the same qualified work — minus the overheads, the travel and the surprises on the invoice.

Windsor 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 Windsor?
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 Windsor or anywhere else in South East.
I searched "corporation tax near me" — is this service really local to Windsor?
Windsor 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 Windsor 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 Windsor clients ask about most
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.
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 Windsor businesses it saves thousands; for others it's pure extra paperwork.
Selling a rental property triggers capital gains tax with a tight reporting window — UK residential sales must be reported and the tax paid within 60 days of completion. It's one of the easiest deadlines in the whole system to miss, and one of the most penalised.
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 Windsor growing towards that line should be watching it monthly.
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.
Receipts win arguments. HMRC doesn't demand a shoebox of paper any more — photos in an app are fine — but every deduction needs evidence behind it. A ten-minute weekly habit beats a January archaeology dig, every time.
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.
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.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Windsor, message us and we'll answer against your actual numbers.
