What Cardiff gets with Bohzo Accountants
Before we touch anything for a Cardiff client, the fee is in writing — and it stays put. Hourly billing doesn't exist here.
Upload, approve, filed. The whole engagement runs from your phone or laptop, on your schedule rather than office hours.
Bohzo Accountants is a trading name of Bohzo Ltd, Company No. 15031604.
Every filing date that applies to you goes in our diary the day you join — and we chase the records, not the other way round.
Compare our fixed corporation tax fees
| Your situation | Fixed fee |
|---|---|
| CT600 with accounts prepared by us | included in accounts packages |
| Standalone CT600 from your accounts | £199 |
| CT600 with capital allowances review | £299 |

“From” pricing reflects the simplest case; anything more complex is quoted as a fixed fee in writing before work begins — and never changes after.
Online accountants vs the high street
Traditional firms around Wales still run on hourly billing, office appointments and fees you discover after the work. We built the opposite: written fixed fees agreed up front, unlimited questions inside the price, and a fully online workflow — no premises anywhere, so no premises priced into your fee in Cardiff.
There's no office to fund in Cardiff 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. You get the same qualified work — minus the overheads, the travel and the surprises on the invoice.
Corporation Tax in Cardiff: from first message to filed
A WhatsApp message from Cardiff is enough to start: what you need, what shape your records are in, any deadline you're worried about.
The quote arrives in writing, covers everything discussed, and is the number you'll actually pay. No revisions later.
Identity checks, engagement letter, secure record upload — all handled from wherever you are in Cardiff. We chase whatever's missing.
Nothing is filed until you've seen and approved it. Once you have, submission is electronic and confirmation comes straight back.
The same service in Cardiff as anywhere — by design
We built this service so that someone in Cardiff never pays a premium — or accepts worse service — because of geography. Same specialists, same published fees, same speed, wherever in Wales you are.
A lot of our Wales clients switched from local firms after one too many surprise invoices. The fix wasn't a cheaper local firm; it was removing the billing model that produces surprises. Fixed fees, in writing, before the work — that's the whole trick.

Cardiff 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 Cardiff?
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 Cardiff or anywhere else in Wales.
I searched "corporation tax near me" — is this service really local to Cardiff?
Cardiff 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 Cardiff town centre or the edge of Wales. 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 Cardiff
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.
The expenses rule is "wholly and exclusively" for the trade — which covers more than most people claim (proportionate home-working costs, business mileage, software subscriptions) and less than some hope (client entertaining, everyday clothing). Knowing the line is where the savings live.
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.
Compare accountants on the things that bite later: is the fee fixed and written down, what exactly is included, who does the work, how fast do they answer in January. Proximity to Cardiff stopped being the differentiator the day filings went electronic.
The best time to switch is after a filing, but it works at any point in the year. What matters is not letting a looming deadline stop you: a new firm can usually pick up an in-flight year faster than you'd think.
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.
A limited company juggles two regulators: Companies House wants accounts within nine months of year end, HMRC wants corporation tax paid at nine months and a day. Same starting point, different documents — and late filing penalties at Companies House escalate automatically and are rarely cancelled.
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.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Cardiff, message us and we'll answer against your actual numbers.
