Castelnau crypto tax FAQs
Do I owe tax if I only swapped one crypto for another?
Usually yes — swapping token A for token B is a disposal for capital gains purposes, as is spending crypto. Only buying with pounds and holding is tax-free. This is the rule that surprises people most.
The CGT allowance is tiny now — does that affect me?
Almost certainly. The annual exempt amount is £3,000, so even modest gains are reportable and taxable. Losses matter more than ever too — registering them lets you offset future gains.
I've had a letter from HMRC about crypto — what now?
Don't ignore it: HMRC sends nudge letters based on exchange data they already hold. We reconstruct your position, calculate anything owed and respond properly — voluntary disclosure is always cheaper than being pursued.
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 "crypto tax 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 crypto tax?
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.
Things worth knowing before your next filing
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.
Compliance checks are usually specific: one return, one figure, one question. Answered promptly and with evidence, most close quickly. The expensive enquiries are the ones that started as unanswered letters.
Compare accountants on the things that bite later: is the fee fixed and written down, what exactly is included, who does the work, how fast do they answer in January. Proximity to Castelnau stopped being the differentiator the day filings went electronic.
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.
If you're a sole trader or landlord anywhere near the £50,000 income mark, Making Tax Digital will change your filing rhythm from 2026: four digital updates a year plus a final declaration. Clients who move their records to software early find the transition a non-event.
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 honest answer changes with your profits. At lower profits, sole trader simplicity usually wins; as profits grow, a limited company's mix of salary and dividends, corporation tax rates and liability protection starts earning its extra admin. We run the actual numbers before recommending either.
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.
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.
