Why Bohzo

What Carmarthen gets with Bohzo Accountants

Never miss a date again

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.

The price is the price

Before we touch anything for a Carmarthen client, the fee is in writing — and it stays put. Hourly billing doesn't exist here.

Everything done online

Upload, approve, filed. The whole engagement runs from your phone or laptop, on your schedule rather than office hours.

Real company, real accountability

What makes us different

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.

Serving Carmarthen

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.

Questions

Carmarthen self assessment tax returns FAQs

What does the £129 fee include?

Preparation and online filing of your full SA100 return, including the supplementary pages your situation needs. If your return is more complex — rental income, capital gains — the packages above show the fixed price, and we confirm it in writing before starting.

I've missed the deadline — can you still help?

Yes. Late returns are common and fixable: we prepare and file the outstanding return quickly, and where there's a reasonable excuse we help you appeal penalties. The sooner it's filed, the sooner the penalties stop growing.

What records do I need to send you?

Income records (invoices, statements, P60/P45 if employed), expense records, and any letters from HMRC. Not sure what counts? Send what you have through the portal and we'll tell you exactly what's missing — chasing paperwork is part of the job.

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 "self assessment 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 self assessment?

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.

Worth knowing

The short version of the rules that matter

Side income and the £1,000 allowance

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.

CIS: refunds hide in the paperwork

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.

Switching accountants is easier than you think

People stay with the wrong accountant for years because switching feels disruptive. In practice the profession has a standard handover process — clearance letters, copies of prior returns and working papers — and the new firm drives it, not you.

Payments on account, decoded

Payments on account catch people out because the first year effectively bills you one-and-a-half years of tax at once. Knowing that in advance changes how you save through the year — and if profits fall, we can apply to reduce the July payment rather than lending HMRC money interest-free.

The VAT registration threshold

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.

Dividends: the allowance is small now

Dividends can only be paid from accumulated profits, and paperwork matters: board minutes and dividend vouchers, dated correctly. "Illegal dividends" isn't dramatic language — overdrawn payments can be reclassified, with tax consequences, if the profits weren't there.

When HMRC writes to you

Scam "HMRC" messages outnumber real ones — HMRC doesn't demand payment by gift card or threaten arrest by text. Real letters have reference numbers that we can verify directly with HMRC before anyone responds.

Landlord tax has its own rules

Selling a rental property triggers capital gains tax with a tight reporting window — UK residential sales must be reported and the tax paid within 60 days of completion. It's one of the easiest deadlines in the whole system to miss, and one of the most penalised.

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.
