Why IGI
Working with Mynyddislwyn businesses
We built the service around what business owners in places like Mynyddislwyn 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 Mynyddislwyn clients.
Nothing is filed for Mynyddislwyn until you have reviewed and approved it. You see the draft, you ask questions, you sign off, then we submit and send you the receipt.
We explain self assessment tax returns in the words Mynyddislwyn business owners use, not in accountant's shorthand, and we show our working so you can check it.
Continuity matters in self assessment tax returns: the person who prepared last year's work for your Mynyddislwyn business prepares this year's, and remembers what was agreed.
Local facts
About Mynyddislwyn
Mynyddislwyn 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
Allowable expenses
Expense claims are where a return is won or lost in an enquiry. The test is wholly and exclusively for the trade; where a cost is mixed, the business proportion can be claimed if it can be identified. Capital items such as equipment and vans are relieved through capital allowances rather than as expenses, except under the cash basis where they are simply deducted when paid.
Record keeping
HMRC requires records of all income and expenses, bank statements, invoices and receipts to be kept for at least five years after the 31 January filing deadline of the tax year they relate to, and companies must keep records for six years from the end of the accounting period. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software.
The 60-day property CGT return
Selling UK residential property that was not your main home for the whole period of ownership triggers a separate Capital Gains Tax return, due within 60 days of completion along with payment of the tax. This is in addition to the annual Self Assessment. The gain is taxed at 18% or 24% depending on your income band, after the £3,000 annual exempt amount.
Crypto records and reporting
HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.
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.
Questions
Questions from Mynyddislwyn
Do you work with businesses in Wales that are not in Mynyddislwyn 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 Mynyddislwyn 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 Mynyddislwyn: 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 Mynyddislwyn 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 Mynyddislwyn 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 Mynyddislwyn really the same price as elsewhere?
Yes. The fee published on this page is what a client in Mynyddislwyn 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 Mynyddislwyn?
No. IGI Accounting is an online-only firm. We serve Mynyddislwyn 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 Mynyddislwyn as anywhere else in the country, and why there is nothing to visit and nothing to print.
