Carshalton South and Clockhouse 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 Carshalton South and Clockhouse?
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 Carshalton South and Clockhouse or anywhere else in South London.
I searched "corporation tax near me" — is this service really local to Carshalton South and Clockhouse?
Carshalton South and Clockhouse 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 Carshalton South and Clockhouse town centre or the edge of South 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
People stay with the wrong accountant for years because switching feels disruptive. In practice the profession has a standard handover process — clearance letters, copies of prior returns and working papers — and the new firm drives it, not you.
Limited companies in CIS reclaim differently to sole traders — through payroll or the company tax return rather than Self Assessment. Plenty of construction companies sit on refundable deductions without realising; a quick review of the CIS position often pays for itself immediately.
The businesses that find January easy are the ones whose bookkeeping happened all year — automatically. Modern software matches bank transactions, files receipts photographed on a phone, and leaves nothing to reconstruct from memory in the new year.
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.
Some businesses register for VAT before they must — reclaiming input VAT can be worth it if your customers are VAT-registered themselves. Others should stay below deliberately. It's a real decision with real numbers, not a formality.
Selling online, freelancing on the side, renting out equipment — each can be a "trade" in HMRC's eyes once it's done with a profit motive. The good news: registering is straightforward, expenses become claimable, and done early it's a non-event.
UK residential property sales have their own regime: report and pay within 60 days of completion, separately from Self Assessment. Other gains report annually. Mixing up the two timetables is a common and expensive mistake.
Selling a rental property triggers capital gains tax with a tight reporting window — UK residential sales must be reported and the tax paid within 60 days of completion. It's one of the easiest deadlines in the whole system to miss, and one of the most penalised.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Carshalton South and Clockhouse, message us and we'll answer against your actual numbers.
