Worth knowing
Rules that come up in this work
Closing a company
A solvent company that has finished its purpose can be dissolved by voluntary strike-off: form DS01 with a £13 Companies House fee, after three months without trading and with all debts paid, final accounts and tax return filed, and assets distributed. HMRC objects to any application where returns or tax are outstanding, so the sequence matters more than the form.
Switching accountants
The main reasons people switch accountant are surprise invoices, missed deadlines and not understanding what they are being told. Switching involves a clearance letter between the firms, a transfer of records and agent authorisations, and a short handover of the current position. It takes about two weeks and should cost nothing extra.
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.
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.
Employer National Insurance
The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.
Allowable expenses
The expenses sole traders most often miss are home working costs, claimed by actual proportion or HMRC's flat rate, the business share of phone and internet, mileage at 45p for the first 10,000 business miles, and training that maintains existing skills. The ones most often claimed wrongly are commuting, entertaining customers and clothes that could be worn outside work.
Questions
Self Assessment Tax Returns questions from Pen-sarn
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.
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.
Do I pay before or after filing?
The fee is invoiced when you approve the draft, before we file. Nothing is submitted to HMRC until it is paid and you have confirmed every figure, and you receive HMRC's submission receipt within minutes of filing.
Can you deal with HMRC on my behalf?
Once you authorise us as your agent we can speak to HMRC about your return, see your account and respond to letters about the return we filed. The authorisation is free, done through your Government Gateway or a code HMRC posts to you, and takes a few days to activate.
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.
Is self assessment tax returns in Pen-sarn really the same price as elsewhere?
Yes. The fee published on this page is what a client in Pen-sarn, Gwynedd 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 Pen-sarn?
No. IGI Accounting is an online-only firm. We serve Pen-sarn, Gwynedd and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically.
