Marylebone High Street 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 Marylebone High Street?
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 Marylebone High Street or anywhere else in Central London.
I searched "corporation tax near me" — is this service really local to Marylebone High Street?
Marylebone High Street 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 Marylebone High Street town centre or the edge of Central 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.
Things worth knowing before your next filing
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.
Register with HMRC by the 5 October after your first tax year of trading, open a separate business account, and put a fixed slice of every payment aside for tax. Do those three things and your first January will be boring — the good kind.
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.
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.
Status under IR35 turns on the reality of the engagement: control, substitution, mutuality of obligation. Contracts matter, but working practices matter more. A written status assessment for each engagement is cheap insurance.
A good accountant should be able to tell you, in plain English, what they'll do, when, and for exactly how much. Vagueness on any of the three is the tell. Everything else — size of firm, fancy office, distance from Marylebone High Street — is decoration.
Payments on account catch people out because the first year effectively bills you one-and-a-half years of tax at once. Knowing that in advance changes how you save through the year — and if profits fall, we can apply to reduce the July payment rather than lending HMRC money interest-free.
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 Marylebone High Street growing towards that line should be watching it monthly.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Marylebone High Street, message us and we'll answer against your actual numbers.
