Carshalton on the Hill 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 on the Hill?
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 on the Hill or anywhere else in South London.
I searched "corporation tax near me" — is this service really local to Carshalton on the Hill?
Carshalton on the Hill 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 on the Hill 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.
From our inbox: what Carshalton on the Hill businesses ask us
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.
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.
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.
Directors paying themselves a salary still need a PAYE scheme and RTI submissions, even in a one-person company. It's a five-minute monthly task with software — and a recurring penalty generator without it.
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.
HMRC receives data directly from online platforms about sellers' income. If a side hustle has grown past the £1,000 trading allowance, coming forward first is always cheaper than being written to — penalties scale with how the disclosure starts.
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.
New companies often have a long first accounting period, which can mean two corporation tax returns for one set of accounts. It's normal, but it's exactly the kind of thing that's cheaper to get right first time than to unpick.
