Online accountants vs the high street
Most local firms near Osterley quote low, bill by the hour and reserve the right to charge for every phone call. 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 Osterley pays the same as everywhere else.
There's no office to fund in Osterley 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.

Osterley 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 Osterley?
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 Osterley or anywhere else in West London.
I searched "self assessment near me" — is this service really local to Osterley?
Osterley 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 Osterley town centre or the edge of 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
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.
CIS deduction statements go missing constantly — contractors change, emails vanish. HMRC's records can fill some gaps, but the fastest refunds belong to subcontractors who keep every monthly statement. If you're in construction around Osterley, that one habit is worth real money.
Miss 31 January and the £100 fine is automatic; three months later daily penalties start. If you're behind on a return, the maths almost always favours filing quickly over waiting — penalties grow on a timetable, and HMRC charges interest either way.
If you contract through your own limited company, IR35 asks whether you'd be an employee without it. For medium and large clients, the status decision is theirs; for small clients, it's still yours — and getting it wrong in either direction costs money.
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.
New companies often have a long first accounting period, which can mean two corporation tax returns for one set of accounts. It's normal, but it's exactly the kind of thing that's cheaper to get right first time than to unpick.
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.
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.
