Online accountants vs the high street
A high-street accountant in Scotland 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 Grangemouth at fees a walk-in office can't match.
There's no office to fund in Grangemouth 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.

The same service in Grangemouth as anywhere — by design
Grangemouth sits in Scotland (FK3), and like everywhere we serve, it gets the identical service and fee as central London — because nothing about our work depends on where you are. What matters is your situation, your records and your deadlines; all three travel over WhatsApp just fine.
A lot of our Scotland clients switched from local firms after one too many surprise invoices. The fix wasn't a cheaper local firm; it was removing the billing model that produces surprises. Fixed fees, in writing, before the work — that's the whole trick.

Grangemouth 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 Grangemouth?
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 Grangemouth or anywhere else in Scotland.
I searched "corporation tax near me" — is this service really local to Grangemouth?
Grangemouth 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 Grangemouth town centre or the edge of Scotland. 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 notes our Grangemouth clients ask about most
Dividends can only be paid from accumulated profits, and paperwork matters: board minutes and dividend vouchers, dated correctly. "Illegal dividends" isn't dramatic language — overdrawn payments can be reclassified, with tax consequences, if the profits weren't there.
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.
Subcontractors under the Construction Industry Scheme have 20% deducted at source — often more than their final tax bill once expenses and the personal allowance are counted. That's why CIS refunds are so common: the average claim is well into four figures, but only if the deduction statements are all gathered.
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.
Online Self Assessment returns are due by 31 January, along with any balancing payment — and HMRC's £100 penalty applies the moment the deadline passes, even if you owe nothing. Most Grangemouth clients who come to us in January still file on time; the records just need to arrive before the last week.
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.
Directors paying themselves a salary still need a PAYE scheme and RTI submissions, even in a one-person company. It's a five-minute monthly task with software — and a recurring penalty generator without it.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Grangemouth, message us and we'll answer against your actual numbers.
