Longthornton 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 Longthornton?
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 Longthornton or anywhere else in South West London.
I searched "corporation tax near me" — is this service really local to Longthornton?
Longthornton 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 Longthornton 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.
Tax, briefly — the parts that affect Longthornton
Online Self Assessment returns are due by 31 January, along with any balancing payment — and HMRC's £100 penalty applies the moment the deadline passes, even if you owe nothing. Most Longthornton clients who come to us in January still file on time; the records just need to arrive before the last week.
MTD for Income Tax starts with the £50,000+ income group in April 2026, with lower bands following. Quarterly digital updates sound worse than they are — with software doing the bookkeeping, the quarters largely take care of themselves.
The July payment on account is the forgotten deadline: no return is due, but money often is. We diary it for every client it applies to, because HMRC charges interest from the day it's late even though nothing was "filed" late.
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.
Company deadlines run off your accounting year end, not the tax year: corporation tax is payable nine months and one day after year end, and the CT600 return is due twelve months after. Confusingly, the payment is due before the return — a sequencing quirk that catches new directors.
The businesses that struggle with tax bills rarely have a tax problem; they have a timing problem. Knowing the bill in September instead of January — which filing early gives you for free — is the difference between planning and scrambling.
Crypto traders rack up hundreds of taxable events without noticing, because every swap counts as a disposal. Specialist software plus the pooling rules turns the mess into a number; guessing does not.
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 Longthornton, that one habit is worth real money.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Longthornton, message us and we'll answer against your actual numbers.
