Derwent Mouth Lock 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 Derwent Mouth Lock?
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 Derwent Mouth Lock or anywhere else in East Midlands.
I searched "self assessment near me" — is this service really local to Derwent Mouth Lock?
Derwent Mouth Lock 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 Derwent Mouth Lock town centre or the edge of East Midlands. 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.
From our inbox: what Derwent Mouth Lock businesses ask us
HMRC receives data directly from online platforms about sellers' income. If a side hustle has grown past the £1,000 trading allowance, coming forward first is always cheaper than being written to — penalties scale with how the disclosure starts.
Disposing of crypto — selling, swapping one coin for another, spending it — is a capital gains event, and staking or mining income is usually income. Exchanges share data with HMRC, so the tax position exists whether or not it's been calculated.
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.
If a return is late because HMRC asked for one you don't actually need, it can sometimes be withdrawn entirely — penalties included. And where there's a genuine reasonable excuse, appeals succeed more often than people expect. The wrong move is ignoring the letters.
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.
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.
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.
If you contract through your own limited company, IR35 asks whether you'd be an employee without it. For medium and large clients, the status decision is theirs; for small clients, it's still yours — and getting it wrong in either direction costs money.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Derwent Mouth Lock, message us and we'll answer against your actual numbers.
