We built the opposite: written fixed fees agreed up front, unlimited questions inside the price, and a fully online workflow — no premises anywhere, so no premises priced into your fee in Caledonian.
There's no office to fund in Caledonian 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.

Caledonian self assessment tax returns FAQs
What does the £129 fee include?
Preparation and online filing of your full SA100 return, including the supplementary pages your situation needs. If your return is more complex — rental income, capital gains — the packages above show the fixed price, and we confirm it in writing before starting.
I've missed the deadline — can you still help?
Yes. Late returns are common and fixable: we prepare and file the outstanding return quickly, and where there's a reasonable excuse we help you appeal penalties. The sooner it's filed, the sooner the penalties stop growing.
What records do I need to send you?
Income records (invoices, statements, P60/P45 if employed), expense records, and any letters from HMRC. Not sure what counts? Send what you have through the portal and we'll tell you exactly what's missing — chasing paperwork is part of the job.
Do I need to visit an office in Caledonian?
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 Caledonian or anywhere else in North London.
I searched "self assessment near me" — is this service really local to Caledonian?
Caledonian 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 Caledonian town centre or the edge of North London. If you'd rather talk it through first, WhatsApp us — a real person answers.
Who will actually handle my self assessment?
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 Caledonian clients ask about most
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 Caledonian stopped being the differentiator the day filings went electronic.
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.
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.
Auto-enrolment applies from the first eligible employee: assess, enrol, contribute, declare. The Pensions Regulator does check, and the fines for ignoring it are out of proportion to how simple compliance actually is.
The trading allowance means up to £1,000 of gross side income per year can be tax-free with no return needed. Above that, registration and reporting kick in — and platforms now report seller data to HMRC, so "under the radar" isn't a strategy any more.
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.
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.
Self Assessment lateness is priced in stages: £100 immediately, daily £10 penalties after three months (up to £900), then percentage-based charges at six and twelve months — all separate from interest on unpaid tax. The curve is designed to reward filing sooner, whatever the state of your records.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Caledonian, message us and we'll answer against your actual numbers.
