Harefield 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 Harefield?
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 Harefield or anywhere else in North West London.
I searched "corporation tax near me" — is this service really local to Harefield?
Harefield 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 Harefield town centre or the edge of North West London. 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.
The short version of the rules that matter
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.
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.
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.
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 Harefield growing towards that line should be watching it monthly.
First-year traders around Harefield 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.
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.
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.
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.
