What makes us different

Online accountants vs the high street

Most local firms near Guildhall quote low, bill by the hour and reserve the right to charge for every phone call. Our model inverts that: the fee is fixed and written down before work begins, questions are part of the service rather than billable events, and everything happens online — the reason Guildhall pays the same as everywhere else.

There's no office to fund in Guildhall 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.

Questions

Guildhall 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 Guildhall?

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 Guildhall or anywhere else in Central London.

I searched "corporation tax near me" — is this service really local to Guildhall?

Guildhall 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 Guildhall town centre or the edge of Central 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.

Worth knowing

Tax, briefly — the parts that affect Guildhall

Capital gains: windows and allowances

The capital gains annual exempt amount has shrunk to £3,000, which pulls far more ordinary disposals — shares, crypto, second properties — into reporting territory. Gains that once fell under the allowance now need a return, even when the tax due is modest.

Tax is a cash-flow event

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.

The 31 January deadline, without the panic

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.

Payroll and pensions for small employers

The first hire brings PAYE registration, Real Time Information submissions every payday, workplace pension auto-enrolment and payslips that must be right. It's all completely manageable — as a monthly routine run by software, not a monthly crisis.

What to actually look for in an accountant

Ask any prospective accountant two questions: "what's included in the fee?" and "what costs extra?" The quality of those two answers predicts the whole relationship.

Allowable expenses: claim what's yours

Most self-employed people under-claim. Use of home, mileage at HMRC's approved rates, phone and broadband apportionment, trade subscriptions, training that updates existing skills — legitimate deductions left on the table add up to real tax overpaid year after year.

Your first year in business

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.

Corporation tax dates work differently

New companies often have a long first accounting period, which can mean two corporation tax returns for one set of accounts. It's normal, but it's exactly the kind of thing that's cheaper to get right first time than to unpick.

General guidance, not personal advice — thresholds and dates change. For advice on your own position in Guildhall, message us and we'll answer against your actual numbers.
