Online accountants vs the high street
A high-street accountant in South East London typically bills by the hour, meets by appointment and prices each extra question. 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 Southend at fees a walk-in office can't match.
There's no office to fund in Southend 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.

Southend corporation tax FAQs
What rate of corporation tax will my company pay?
19% on profits up to £50,000, 25% above £250,000, and marginal relief in between — an effective rate that climbs gradually. Associated companies split those thresholds, which catches many owners with more than one company. We calculate it precisely.
The payment is due before the return — is that right?
Yes, oddly: payment is due 9 months and 1 day after year end, but the return itself isn't due until 12 months. We prepare everything well before the payment date so you know the bill with time to plan.
Can you review whether I've missed reliefs in past years?
Yes — you can generally amend a CT600 up to 12 months after its filing deadline, and some claims reach back further. If you think allowances went unclaimed, we'll review and quote a fixed fee for any amendment worth making.
Do I need to visit an office in Southend?
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 Southend or anywhere else in South East London.
I searched "corporation tax near me" — is this service really local to Southend?
Southend 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 Southend town centre or the edge of South East London. If you'd rather talk it through first, WhatsApp us — a real person answers.
Who will actually handle my corporation 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.
From our inbox: what Southend businesses ask us
The businesses that struggle with tax bills rarely have a tax problem; they have a timing problem. Knowing the bill in September instead of January — which filing early gives you for free — is the difference between planning and scrambling.
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 Southend growing towards that line should be watching it monthly.
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.
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.
Inside-IR35 and outside-IR35 engagements need different setups — sometimes umbrella, sometimes the company, sometimes both across a year. Contractors who plan this per-engagement keep more and worry less.
Changing accountant mid-year is routine: you authorise the new firm, we write a professional clearance letter to the old one, records transfer, and HMRC authorisation moves online. Clients are usually surprised the whole thing needs almost nothing from them.
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.
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.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Southend, message us and we'll answer against your actual numbers.
