Online accountants vs the high street
A high-street accountant in South West London typically bills by the hour, meets by appointment and prices each extra question.

You get the same qualified work — minus the overheads, the travel and the surprises on the invoice.

Longthornton 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 Longthornton?
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 Longthornton or anywhere else in South West London.
I searched "self assessment near me" — is this service really local to Longthornton?
Longthornton 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 Longthornton town centre or the edge of South West London. 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.
Things worth knowing before your next filing
Can't pay the bill by the deadline? File anyway. Filing and payment are penalised separately, and HMRC's Time to Pay arrangements can spread the bill — but only once the return is in. Not filing because you can't pay turns one problem into two.
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.
Most self-employed people under-claim. Use of home, mileage at HMRC's approved rates, phone and broadband apportionment, trade subscriptions, training that updates existing skills — legitimate deductions left on the table add up to real tax overpaid year after year.
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.
Good records aren't about neatness — they're about money: claims you can evidence, VAT you can reclaim, and an accountant who spends billable time on advice rather than sorting. Bank feeds plus a receipts app gets most small businesses to "tidy" in minutes a week.
The first tax bill is the hardest because it can arrive with payments on account attached — up to 150% of the year's tax in one go. New businesses that save a quarter to a third of profits from day one never feel it.
Ask any prospective accountant two questions: "what's included in the fee?" and "what costs extra?" The quality of those two answers predicts the whole relationship.
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.
