Why IGI
Working with Pentraeth businesses
We built the service around what business owners in places like Pentraeth actually complain about: not knowing what the accountant will charge, finding out about a deadline after it has passed, and receiving a set of accounts with no explanation. Each is fixed by design: fixed fees, deadline tracking shown on every page, and a plain-English summary with every draft for Pentraeth clients.
Approval before filing is a rule, not a courtesy. For self assessment tax returns in Pentraeth, every submission to HMRC or Companies House follows your written go-ahead.
The output for Pentraeth clients is never just a form. It is the form, a one-page summary of what it says, and a note of the decisions it points to for self assessment tax returns.
A named person handles your self assessment tax returns from Pentraeth and knows the file, so you are not re-explaining your business to a different helpdesk each time.
Local facts
About Pentraeth
Pentraeth sits in Wales, postcode district LL75. 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
Corporation Tax rates and marginal relief
Companies pay Corporation Tax at 19% on profits up to £50,000 and 25% on profits over £250,000. Between those figures marginal relief applies, producing an effective rate that rises gradually and a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies, so a director with two companies has thresholds of £25,000 and £125,000 for each.
The VAT registration threshold
Watching the rolling twelve-month turnover figure is one of the quiet jobs of monthly bookkeeping, because the £90,000 VAT threshold arrives silently. Crossing it brings quarterly returns, Making Tax Digital software and a decision about schemes. Crossing it late brings a bill for VAT you could not recover from customers and a penalty for failing to notify.
Making Tax Digital for Income Tax
Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.
Late filing penalties
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
Payments on account
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
Questions
Questions from Pentraeth
Do you work with businesses in Wales that are not in Pentraeth itself?
Yes. Every place in Wales has its own page on this site and the same fees apply throughout. The nearest-places list on this page links to them. Wherever in Wales your business is based, the service is identical because none of it depends on where you are.
What if my Pentraeth business is a partnership or an LLP?
Both are covered. Partnerships need a partnership return and a Self Assessment for each partner; LLPs file accounts with Companies House under company-style rules as well. We quote a fixed fee for the set based on the number of partners or members, and the process is the same as for any other client in Pentraeth: records in, draft out, approve, filed.
Are your fees inclusive of everything?
Our fee covers the work described for the package. Companies House fees, such as £100 to incorporate or £50 for a confirmation statement, are charged separately and passed on at cost. Software subscriptions are in your own name. There is nothing else: no hourly extras, no charge for questions, and no additional year-end invoice for Pentraeth clients on monthly packages.
How quickly do you respond?
In UK working hours, usually within a few hours and always the same working day. Each Pentraeth client has a named contact who knows the file. Outside working hours, WhatsApp and email messages are picked up first thing the next morning. In January and at other peak times we tell you your turnaround when you book rather than leaving you guessing.
Is self assessment tax returns in Pentraeth really the same price as elsewhere?
Yes. The fee published on this page is what a client in Pentraeth pays and what a client in any other part of Wales pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
Do you have an office in Pentraeth?
No. IGI Accounting is an online-only firm. We serve Pentraeth and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for self assessment tax returns is the same in Pentraeth as anywhere else in the country, and why there is nothing to visit and nothing to print.
