Castelnau hmrc investigation support FAQs
I've received a compliance check letter — how bad is it?
Usually less bad than it reads. Most checks focus on one aspect — a expenses category, a VAT period, a source of income HMRC can see but your return doesn't show. The response strategy matters enormously: answer exactly what's asked, accurately, with nothing extra. That's the £299 first stage, and many checks end there.
What if I know there's actually something wrong?
Then a voluntary disclosure — made before HMRC finds it — is dramatically cheaper in penalties, sometimes the difference between 0–30% and up to 100% of the tax. We prepare the numbers, present the disclosure and negotiate the settlement. It's the conversation people put off for years and resolve in weeks.
Can you take over an investigation that's already underway?
Yes — we're appointed as your agent, HMRC redirects correspondence to us, and we review everything already said before anything else goes out. Mid-enquiry rescues are common; the file usually looks better than the stress suggests.
Do I need to visit an office in Castelnau?
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 Castelnau or anywhere else in South West London.
I searched "hmrc investigation support near me" — is this service really local to Castelnau?
Castelnau 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 Castelnau town centre or the edge of South West London. If you'd rather talk it through first, WhatsApp us — a real person answers.
Who will actually handle my hmrc investigation support?
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 notes our Castelnau clients ask about most
Register with HMRC by the 5 October after your first tax year of trading, open a separate business account, and put a fixed slice of every payment aside for tax. Do those three things and your first January will be boring — the good kind.
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.
Every tax bill is predictable months in advance — which makes tax the most plannable cost a business has. A separate tax savings account, fed a fixed percentage of every sale, converts January from a crisis into a transfer.
Selling online, freelancing on the side, renting out equipment — each can be a "trade" in HMRC's eyes once it's done with a profit motive. The good news: registering is straightforward, expenses become claimable, and done early it's a non-event.
Since Section 24, individual landlords can't deduct mortgage interest as an expense — it's a 20% tax credit instead, which pushes some higher-rate landlords into surprising bills. Whether to hold property personally or through a company is now a genuine question with genuine trade-offs.
The businesses that find January easy are the ones whose bookkeeping happened all year — automatically. Modern software matches bank transactions, files receipts photographed on a phone, and leaves nothing to reconstruct from memory in the new year.
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.
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.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Castelnau, message us and we'll answer against your actual numbers.
