Online accountants vs the high street
Traditional firms around Central London still run on hourly billing, office appointments and fees you discover after the work. We work the other way round: one fixed fee agreed in writing before anything starts, every question included, and the whole engagement handled online — which is exactly why we can serve Mansion House at fees a walk-in office can't match.
There's no office to fund in Mansion House 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.

Being in London, Mansion House clients often come to us comparing against firms charging central-London rates for the same compliance work. The work is identical; the overheads aren't — and since we carry no premises anywhere, our fees don't care about postcodes.

Mansion House 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 Mansion House?
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 Mansion House or anywhere else in Central London.
I searched "startup accounting near me" — is this service really local to Mansion House?
Mansion House 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 Mansion House town centre or the edge of Central 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 Mansion House businesses ask us
Dividends can only be paid from accumulated profits, and paperwork matters: board minutes and dividend vouchers, dated correctly. "Illegal dividends" isn't dramatic language — overdrawn payments can be reclassified, with tax consequences, if the profits weren't there.
Timing disposals across tax years, using losses properly, and the spousal transfer rules can all legitimately reduce capital gains bills — but only before the sale. CGT planning after completion is just arithmetic.
Receipts win arguments. HMRC doesn't demand a shoebox of paper any more — photos in an app are fine — but every deduction needs evidence behind it. A ten-minute weekly habit beats a January archaeology dig, every time.
First-year traders around Mansion House tend to make the same three mistakes: registering late, mixing business and personal spending in one account, and saving nothing for the first tax bill. All three are avoidable in an afternoon of setup.
From April 2026, self-employed people and landlords with qualifying income over £50,000 move onto Making Tax Digital for Income Tax: digital records and quarterly updates to HMRC, not one annual return. The year before is the right time to get bookkeeping into shape.
Scam "HMRC" messages outnumber real ones — HMRC doesn't demand payment by gift card or threaten arrest by text. Real letters have reference numbers that we can verify directly with HMRC before anyone responds.
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.
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 Mansion House, message us and we'll answer against your actual numbers.
