There's no office to fund in Canonbury and no office to visit: records travel through our secure portal or WhatsApp, approvals happen on your phone, and filings go to HMRC and Companies House electronically.

Canonbury 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 Canonbury?
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 Canonbury or anywhere else in North London.
I searched "corporation tax near me" — is this service really local to Canonbury?
Canonbury 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 Canonbury town centre or the edge of North 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 Canonbury businesses ask us
If you're a sole trader or landlord anywhere near the £50,000 income mark, Making Tax Digital will change your filing rhythm from 2026: four digital updates a year plus a final declaration. Clients who move their records to software early find the transition a non-event.
Rental profits need reporting once they're more than trivial, and the rules differ for furnished holiday lets, rent-a-room and ordinary lets. Landlords are also in the first wave of Making Tax Digital — property income counts towards the £50,000 threshold.
The trading allowance means up to £1,000 of gross side income per year can be tax-free with no return needed. Above that, registration and reporting kick in — and platforms now report seller data to HMRC, so "under the radar" isn't a strategy any more.
If your last Self Assessment bill was over £1,000, HMRC usually asks for next year's tax in advance — half on 31 January, half on 31 July. It's the number-one cause of "why is my bill double?" calls, and it's manageable: if your income has dropped, the payments can be reduced with a claim.
Status under IR35 turns on the reality of the engagement: control, substitution, mutuality of obligation. Contracts matter, but working practices matter more. A written status assessment for each engagement is cheap insurance.
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.
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 Canonbury clients who come to us in January still file on time; the records just need to arrive before the last week.
Auto-enrolment applies from the first eligible employee: assess, enrol, contribute, declare. The Pensions Regulator does check, and the fines for ignoring it are out of proportion to how simple compliance actually is.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Canonbury, message us and we'll answer against your actual numbers.
