St. Mark's 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 St. Mark's?
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 St. Mark's or anywhere else in South West London.
I searched "corporation tax near me" — is this service really local to St. Mark's?
St. Mark's 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 St. Mark's town centre or the edge of South 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.
From our inbox: what St. Mark's 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.
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.
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.
The capital gains annual exempt amount has shrunk to £3,000, which pulls far more ordinary disposals — shares, crypto, second properties — into reporting territory. Gains that once fell under the allowance now need a return, even when the tax due is modest.
The first hire brings PAYE registration, Real Time Information submissions every payday, workplace pension auto-enrolment and payslips that must be right. It's all completely manageable — as a monthly routine run by software, not a monthly crisis.
The best salary-dividend mix moves with each year's thresholds and your other income. Setting it once in April — rather than guessing through the year — is one of the simplest pieces of planning a director can do.
Plenty of people incorporate too early because it "sounds established", then pay for accounts, confirmation statements and payroll they didn't need. The switch pays for itself at the right profit level — the trick is knowing yours.
CIS deduction statements go missing constantly — contractors change, emails vanish. HMRC's records can fill some gaps, but the fastest refunds belong to subcontractors who keep every monthly statement. If you're in construction around St. Mark's, that one habit is worth real money.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in St. Mark's, message us and we'll answer against your actual numbers.
