Compare our fixed corporation tax fees
| Your situation | Fixed fee |
|---|---|

| Standalone CT600 from your accounts | £199 |

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 work the other way round: one fixed fee agreed in writing before anything starts, every question included, and the whole engagement handled online — which is exactly why we can serve Carmarthen at fees a walk-in office can't match.
There's no office to fund in Carmarthen 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 Carmarthen: from first message to filed
Start with a message — no forms, no phone queue. Tell us what needs doing and we take it from there.
One fixed price before any work starts. Complex case? We say so now, not on the invoice.
The legal bits — ID verification, engagement letter — happen online in minutes, then your records come in via the portal or WhatsApp.
We prepare, you check and approve, we submit — and you get the HMRC confirmation the same day it's filed.
The same service in Carmarthen as anywhere — by design
We built this service so that someone in Carmarthen 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.

Carmarthen 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 Carmarthen?
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 Carmarthen or anywhere else in Wales.
I searched "corporation tax near me" — is this service really local to Carmarthen?
Carmarthen 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 Carmarthen 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.
From our inbox: what Carmarthen businesses ask us
From April 2026, self-employed people and landlords with qualifying income over £50,000 move onto Making Tax Digital for Income Tax: digital records and quarterly updates to HMRC, not one annual return. The year before is the right time to get bookkeeping into shape.
First-year traders around Carmarthen tend to make the same three mistakes: registering late, mixing business and personal spending in one account, and saving nothing for the first tax bill. All three are avoidable in an afternoon of setup.
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.
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.
Subcontractors under the Construction Industry Scheme have 20% deducted at source — often more than their final tax bill once expenses and the personal allowance are counted. That's why CIS refunds are so common: the average claim is well into four figures, but only if the deduction statements are all gathered.
VAT registration becomes compulsory once your taxable turnover in any rolling 12 months passes £90,000 — and "rolling" is the word that catches people, because it's not your accounting year. Businesses in Carmarthen growing towards that line should be watching it monthly.
If a return is late because HMRC asked for one you don't actually need, it can sometimes be withdrawn entirely — penalties included. And where there's a genuine reasonable excuse, appeals succeed more often than people expect. The wrong move is ignoring the letters.
A good accountant should be able to tell you, in plain English, what they'll do, when, and for exactly how much. Vagueness on any of the three is the tell. Everything else — size of firm, fancy office, distance from Carmarthen — is decoration.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Carmarthen, message us and we'll answer against your actual numbers.
