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. 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 Harmondsworth pays the same as everywhere else.
There's no office to fund in Harmondsworth 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.

Harmondsworth 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 Harmondsworth?
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 Harmondsworth or anywhere else in West London.
I searched "startup accounting near me" — is this service really local to Harmondsworth?
Harmondsworth 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 Harmondsworth 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.
From our inbox: what Harmondsworth businesses ask us
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.
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.
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 capital gains annual exempt amount has shrunk to £3,000, which pulls far more ordinary disposals — shares, crypto, second properties — into reporting territory. Gains that once fell under the allowance now need a return, even when the tax due is modest.
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.
The July payment on account is the forgotten deadline: no return is due, but money often is. We diary it for every client it applies to, because HMRC charges interest from the day it's late even though nothing was "filed" late.
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.
A limited company juggles two regulators: Companies House wants accounts within nine months of year end, HMRC wants corporation tax paid at nine months and a day. Same starting point, different documents — and late filing penalties at Companies House escalate automatically and are rarely cancelled.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Harmondsworth, message us and we'll answer against your actual numbers.
