Why IGI
Working with Onllwyn businesses
Clients in Onllwyn are not a branch or a territory to us; they are files handled by the same team that serves the rest of the UK, at the same price. The fee you see is confirmed in writing before work starts. The dates you see are diarised and chased. And the person who prepares your first return is the person who prepares the next one.
We work to the HMRC and Companies House calendar, not an appointment diary. Clients in Onllwyn get reminders at 60, 30 and 7 days before each date that applies to self assessment tax returns.
No hourly rate and no surprise invoice. Onllwyn clients know the fee for self assessment tax returns before they send a single document, and it stays fixed.
Continuity matters in self assessment tax returns: the person who prepared last year's work for your Onllwyn business prepares this year's, and remembers what was agreed.
Local facts
About Onllwyn
Onllwyn sits in Wales. Businesses in Wales file with the same HMRC and Companies House as England, and for now the Welsh rates of income tax equal the English ones, though the Senedd can vary them. The practical differences are Land Transaction Tax on property and Welsh-specific business support schemes, and company names and documents may be in Welsh.

Worth knowing
Rules that affect most businesses here
Workplace pensions and auto-enrolment
Workplace pension compliance is part of payroll, not separate from it. Each pay period the payroll assesses who is eligible, calculates employer and employee contributions on qualifying earnings between the lower and upper thresholds, and sends the contribution file to the scheme. The minimum total is 8%, and many employers choose to contribute more as a recruitment advantage.
Employer National Insurance
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
The trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Dormant companies
Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.
The 60-day property CGT return
The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.
Questions
Questions from Onllwyn
I already have an accountant in Onllwyn. How hard is it to switch?
It takes about two weeks and costs nothing extra. You authorise us, we write to your current accountant for professional clearance and your records, and we transfer the agent authorisations. We pick up the next filing without a gap. You do not need to wait for a year end, and we tell you honestly if switching mid-job would be awkward.
Can you deal with HMRC and Companies House for me?
Yes. Once you authorise us as your agent, HMRC and Companies House correspond with us about the filings we make for your Onllwyn business, and we can see your accounts and respond on your behalf. Authorisation is free and takes a few days to activate. Routine correspondence about work we have filed is handled at no extra charge.
Why are the fees the same in Onllwyn as in London?
Because the cost of an accountant is mostly premises and that is a cost we do not have. The work is done online by UK-based staff, so a client in Onllwyn pays exactly the published fee, as does a client in central London or a Highland village. The fee is confirmed in writing before anything starts.
Which services are available in Onllwyn?
Every service on this page is available to businesses and individuals in Onllwyn, at the fee shown. Core compliance work, accounts, tax returns, bookkeeping, VAT, payroll and company formation, is listed with its own local page. Specialist services such as R&D, crypto tax and HMRC enquiry support are national services delivered the same way from anywhere in the UK.
How do I get started from Onllwyn?
Message us on WhatsApp or email with a sentence about your business and what you need. We reply in working hours with any questions and a fixed fee for self assessment tax returns. Once you confirm, we tell you exactly which records to send and the work begins. Most Onllwyn clients are set up within a day.
Which deadlines matter most for self assessment tax returns?
The next four dates that apply to self assessment tax returns are shown at the top of this page, calculated from today. For Onllwyn clients we diarise every one of them from the day you join and send reminders before each, so the work is done in good time rather than in the last week before a penalty.
