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.

One fixed price before any work starts. Complex case? We say so now, not on the invoice.

The same service in Mansion House as anywhere — by design
Mansion House sits in Central London (EC4V), and like everywhere we serve, it gets the identical service and fee as central London — because nothing about our work depends on where you are. What matters is your situation, your records and your deadlines; all three travel over WhatsApp just fine.
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 contractor accountants FAQs
How does IR35 affect me?
If a contract is 'inside IR35', tax is broadly like employment; outside, you keep the company's flexibility on salary and dividends. Since the off-payroll rules, medium and large clients determine status — but the risk and planning still land on you. We review contracts and working practices so you know where each engagement stands.
What's the most tax-efficient way to pay myself?
Typically a modest salary (keeping NI credits) plus dividends from post-tax profits, reviewed each April as thresholds move. It depends on your other income and pension plans — the review is included in every package.
Can I switch accountants mid-contract?
Yes, any time. We handle professional clearance with your current accountant and take over the records — most switches complete within two weeks with nothing for your agency or client to notice.
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 "contractor 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 contractor 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 Mansion House
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.
Subcontractors under the Construction Industry Scheme have 20% deducted at source — often more than their final tax bill once expenses and the personal allowance are counted. That's why CIS refunds are so common: the average claim is well into four figures, but only if the deduction statements are all gathered.
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.
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.
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.
Every year a wave of returns gets filed in the final days of January. It works, but it's the most expensive way to do it: no time to check for missed reliefs, and any tax due lands as one surprise. Sending your records early — even unsorted — is the single best gift you can give your January self.
Directors paying themselves a salary still need a PAYE scheme and RTI submissions, even in a one-person company. It's a five-minute monthly task with software — and a recurring penalty generator without it.
VAT registration becomes compulsory once your taxable turnover in any rolling 12 months passes £90,000 — and "rolling" is the word that catches people, because it's not your accounting year. Businesses in Mansion House growing towards that line should be watching it monthly.
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.
