Isle of Dogs 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 Isle of Dogs?
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 Isle of Dogs or anywhere else in East London.
I searched "corporation tax near me" — is this service really local to Isle of Dogs?
Isle of Dogs 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 Isle of Dogs town centre or the edge of East 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.
Tax, briefly — the parts that affect Isle of Dogs
Good records aren't about neatness — they're about money: claims you can evidence, VAT you can reclaim, and an accountant who spends billable time on advice rather than sorting. Bank feeds plus a receipts app gets most small businesses to "tidy" in minutes a week.
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.
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 Isle of Dogs growing towards that line should be watching it monthly.
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.
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.
Subcontractors under the Construction Industry Scheme have 20% deducted at source — often more than their final tax bill once expenses and the personal allowance are counted. That's why CIS refunds are so common: the average claim is well into four figures, but only if the deduction statements are all gathered.
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.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Isle of Dogs, message us and we'll answer against your actual numbers.
