Compare our fixed self assessment tax returns fees
| Your situation | Fixed fee |
|---|---|
| Straightforward return — one income source | £129 |
| With rental property income | £169 |
| With capital gains (property, shares, crypto) | £199 |
| Late-return rescue — filed fast, penalties appealed where possible | £179 |
“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 South West still run on hourly billing, office appointments and fees you discover after the work. 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 Marlborough pays the same as everywhere else.
There's no office to fund in Marlborough 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.
Self Assessment Tax Returns in Marlborough: from first message to filed
A WhatsApp message from Marlborough 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 Marlborough. 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 Marlborough as anywhere — by design
Marlborough sits in South West (SN8), and like everywhere we serve, it gets the identical service and fee as central London — because nothing about our work depends on where you are. What matters is your situation, your records and your deadlines; all three travel over WhatsApp just fine.
Smaller towns like Marlborough are exactly why we work online: the nearest high-street firm may be a drive away, keep office hours, and price like scarcity. Your accountant should be as close as your phone — and priced like competition exists.

Marlborough 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 Marlborough?
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 Marlborough or anywhere else in South West.
I searched "self assessment near me" — is this service really local to Marlborough?
Marlborough 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 Marlborough town centre or the edge of South West. 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.
The short version of the rules that matter
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.
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.
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.
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.
The £90,000 VAT threshold is measured over any 12-month rolling window, so a strong few months can tip you over mid-year. There's a 30-day window to register once you cross it; miss that and HMRC can backdate the liability to when you should have registered.
The first hire brings PAYE registration, Real Time Information submissions every payday, workplace pension auto-enrolment and payslips that must be right. It's all completely manageable — as a monthly routine run by software, not a monthly crisis.
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.
Plenty of people incorporate too early because it "sounds established", then pay for accounts, confirmation statements and payroll they didn't need. The switch pays for itself at the right profit level — the trick is knowing yours.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Marlborough, message us and we'll answer against your actual numbers.
