Online accountants vs the high street
Traditional firms around West London still run on hourly billing, office appointments and fees you discover after the work. We built the opposite: written fixed fees agreed up front, unlimited questions inside the price, and a fully online workflow — no premises anywhere, so no premises priced into your fee in Sipson.
There's no office to fund in Sipson 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.

Sipson startup accountants FAQs
What is SEIS/EIS advance assurance and do I need it?
It's HMRC's provisional confirmation that investment in your company qualifies for SEIS/EIS tax relief — and most angels won't invest without it. We prepare and submit the application, including the business plan framing HMRC expects.
We haven't made any money yet — do we still need an accountant?
Your filing duties start at incorporation, revenue or not — accounts, confirmation statements, corporation tax registration. Getting software and structure right from day one is also dramatically cheaper than untangling a year of DIY records later.
Can you handle share options and multiple share classes?
Yes — growth shares, EMI options and investor share classes are common startup territory. We'll flag when you need a specialist valuation and handle the accounting and filings around it.
Do I need to visit an office in Sipson?
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 Sipson or anywhere else in West London.
I searched "startup accounting near me" — is this service really local to Sipson?
Sipson 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 Sipson 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 startup accounting?
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.
Tax, briefly — the parts that affect Sipson
HMRC runs nudge-letter campaigns to crypto holders based on exchange data. If there are undeclared gains in past years, a voluntary disclosure is dramatically cheaper than waiting for the letter — penalties are scaled to cooperation.
The tax-free dividend allowance is down to £500, so almost any director taking dividends now pays some dividend tax — and needs a Self Assessment return to report it. The classic small-salary-plus-dividends strategy still works; it just needs actual planning rather than folklore.
Changing accountant mid-year is routine: you authorise the new firm, we write a professional clearance letter to the old one, records transfer, and HMRC authorisation moves online. Clients are usually surprised the whole thing needs almost nothing from them.
Some businesses register for VAT before they must — reclaiming input VAT can be worth it if your customers are VAT-registered themselves. Others should stay below deliberately. It's a real decision with real numbers, not a formality.
Filing early doesn't mean paying early: submit a return in May and the tax is still not due until the usual dates. Early filing buys certainty, refund speed and time to arrange payment — it costs nothing.
Limited companies in CIS reclaim differently to sole traders — through payroll or the company tax return rather than Self Assessment. Plenty of construction companies sit on refundable deductions without realising; a quick review of the CIS position often pays for itself immediately.
UK residential property sales have their own regime: report and pay within 60 days of completion, separately from Self Assessment. Other gains report annually. Mixing up the two timetables is a common and expensive mistake.
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.
