Local facts
About Tregarth
Tregarth is in Wales, in the LL57 postcode district, 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 come up in this work
Closing a company
Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.
Switching accountants
You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.
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.
Crypto records and reporting
Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.
Allowable expenses
An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.
Record keeping
Record keeping is a legal obligation with a penalty of up to £3,000 for failure, but its real value is in making every other filing cheaper and more defensible. Keep invoices, receipts, bank statements, mileage logs and any HMRC correspondence, digitally if you like, for five years after the relevant filing deadline for individuals and six years for companies and VAT.
Workplace pensions and auto-enrolment
Every employer must assess its workers for automatic enrolment from the first employee's start date. Those aged 22 to State Pension age earning over £10,000 a year must be enrolled into a qualifying pension with minimum contributions of 8% of qualifying earnings, at least 3% from the employer, and a declaration of compliance made to the Pensions Regulator within five months.
Questions
Self Assessment Tax Returns questions from Tregarth
I am employed and have a small side income. Do I need a return?
If the side income is under £1,000 a year the trading allowance covers it and no return is needed. Above that you must register and file. If the side income is the only reason for the return, the £129 package applies and we make sure your PAYE figures from the P60 are reconciled correctly.
Will Making Tax Digital change my return?
From April 2026 sole traders and landlords with qualifying income over £50,000 send quarterly updates to HMRC through software, with the £30,000 threshold following in April 2027. The year-end return becomes a final declaration. We set this up through our bookkeeping service when it applies to you.
What happens after you file?
You receive HMRC's submission receipt, a PDF of the return, the tax computation and a payment schedule with HMRC's bank details and your payment reference. We diarise next year's deadlines for you and send reminders before each one.
What records should I keep, and for how long?
Invoices, bank statements, receipts, P60s and P45s, dividend vouchers and any HMRC letters. Keep them for at least five years after the 31 January filing deadline of the tax year they relate to. Photos and PDFs are acceptable to HMRC; paper is not required.
Do you handle Scottish or Welsh income tax?
Yes. Scottish taxpayers have six bands from 19% to 48% and Welsh taxpayers have Welsh rates set by the Senedd, both applied automatically from the residence HMRC holds for you. We check that address is right, because an out-of-date one is a common cause of wrong tax codes.
Which expenses can I claim as a sole trader?
Costs that are wholly and exclusively for the business: materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees and bank charges. If your expenses are under £1,000 the trading allowance may be better, and we check both.
