Local facts
About Trearddur Bay
Trearddur Bay sits in Wales. Welsh taxpayers pay Welsh rates of income tax, set by the Senedd and currently matching the English bands, collected under a C-prefixed tax code. National Insurance, VAT and Corporation Tax are UK-wide. Property purchases in Wales pay Land Transaction Tax to the Welsh Revenue Authority rather than Stamp Duty, with its own bands and rates.

Worth knowing
Rules that affect most businesses here
Confirmation statements and identity verification
Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
Late filing penalties
Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.
Making Tax Digital for Income Tax
MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.
The Self Assessment calendar
The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.
Questions
Questions from Trearddur Bay
Which services are available in Trearddur Bay?
Every service on this page is available to businesses and individuals in Trearddur Bay, 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.
Why are the fees the same in Trearddur Bay 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 Trearddur Bay 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.
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 Trearddur Bay 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.
I already have an accountant in Trearddur Bay. 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.
Do you have an office in Trearddur Bay?
No. IGI Accounting is an online-only firm. We serve Trearddur Bay 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 Trearddur Bay as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is self assessment tax returns in Trearddur Bay really the same price as elsewhere?
Yes. The fee published on this page is what a client in Trearddur Bay 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.
