Tower of London 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 Tower of London?
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 Tower of London or anywhere else in Central London.
I searched "corporation tax near me" — is this service really local to Tower of London?
Tower of London 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 Tower of London 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.
Tax, briefly — the parts that affect Tower of London
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.
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.
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 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.
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.
Most HMRC letters are routine — a statement, a code change, a reminder. The rule is simple: never ignore one, and never panic over one. Forwarded to your accountant the day it arrives, almost every letter is a five-minute job.
The £90,000 VAT threshold is measured over any 12-month rolling window, so a strong few months can tip you over mid-year. There's a 30-day window to register once you cross it; miss that and HMRC can backdate the liability to when you should have registered.
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.
