Questions

Mill Hill 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 Mill Hill?

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 Mill Hill or anywhere else in North London.

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

Mill Hill 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 Mill Hill 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 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

From our inbox: what Mill Hill businesses ask us

Payroll and pensions for small employers

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.

CIS: refunds hide in the paperwork

Limited companies in CIS reclaim differently to sole traders — through payroll or the company tax return rather than Self Assessment. Plenty of construction companies sit on refundable deductions without realising; a quick review of the CIS position often pays for itself immediately.

What to actually look for in an accountant

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 Mill Hill stopped being the differentiator the day filings went electronic.

Side income and the £1,000 allowance

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.

Payments on account, decoded

If your last Self Assessment bill was over £1,000, HMRC usually asks for next year's tax in advance — half on 31 January, half on 31 July. It's the number-one cause of "why is my bill double?" calls, and it's manageable: if your income has dropped, the payments can be reduced with a claim.

Landlord tax has its own rules

Since Section 24, individual landlords can't deduct mortgage interest as an expense — it's a 20% tax credit instead, which pushes some higher-rate landlords into surprising bills. Whether to hold property personally or through a company is now a genuine question with genuine trade-offs.

Penalties escalate on a timetable

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.

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.
