Online accountants vs the high street
A high-street accountant in West London typically bills by the hour, meets by appointment and prices each extra question. Our model inverts that: the fee is fixed and written down before work begins, questions are part of the service rather than billable events, and everything happens online — the reason Chiswick pays the same as everywhere else.

You get the same qualified work — minus the overheads, the travel and the surprises on the invoice.

Chiswick 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 Chiswick?
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 Chiswick or anywhere else in West London.
I searched "corporation tax near me" — is this service really local to Chiswick?
Chiswick 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 Chiswick town centre or the edge of 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 Chiswick businesses ask us
Can't pay the bill by the deadline? File anyway. Filing and payment are penalised separately, and HMRC's Time to Pay arrangements can spread the bill — but only once the return is in. Not filing because you can't pay turns one problem into two.
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 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.
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.
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 Chiswick clients who come to us in January still file on time; the records just need to arrive before the last week.
Inside-IR35 and outside-IR35 engagements need different setups — sometimes umbrella, sometimes the company, sometimes both across a year. Contractors who plan this per-engagement keep more and worry less.
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.
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.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Chiswick, message us and we'll answer against your actual numbers.
