Local facts
About Castell
Castell is in Wales, 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 come up in this work
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
Dormant companies
A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.
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.
Crypto records and reporting
Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.
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.
Record keeping
Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.
Questions
Sole Trader Accounts questions from Castell
Do I need accounts as well as a tax return?
HMRC requires a profit figure on the self-employment pages, and the accounts are how that figure is produced and supported. Very small businesses can complete the three-line account on the return, but once turnover is meaningful, proper accounts protect you in an enquiry and show you how the business is actually doing. The £229 bundle includes both.
When does Making Tax Digital apply to me?
From April 2026 if your combined self-employment and property income was over £50,000 in 2024/25; from April 2027 if over £30,000; and planned for April 2028 if over £20,000. It means digital records and quarterly updates to HMRC. Our bookkeeping service handles it, and we tell you your start date as part of the accounts work.
What records do I have to keep?
Records of all sales and takings, all purchases and expenses, and bank statements, for at least five years after the 31 January filing deadline of the relevant tax year. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software from your start date.
How are vehicles treated?
You can claim actual running costs with a business-use percentage plus capital allowances on the vehicle, or HMRC's simplified mileage rate of 45p a mile for the first 10,000 business miles and 25p after that. Once you choose a method for a vehicle you keep it. We compare both for your mileage and show the difference.
What National Insurance do sole traders pay?
Class 4 at 6% on profits between £12,570 and £50,270 and 2% above that, collected through Self Assessment. Class 2 is no longer compulsory; profits above £7,105 earn National Insurance credits automatically, and below that you can pay Class 2 voluntarily at £3.65 a week to protect your State Pension record.
I started trading part-way through the year. What is my first accounting period?
Since the basis period reform, sole traders are taxed on profits of the tax year, 6 April to 5 April, regardless of accounting date. A first period runs from your start date to 5 April. If you prefer a different accounting date we apportion the profits, but for most new traders a 5 April year end is simplest.
Do you have an office in Castell?
No. IGI Accounting is an online-only firm. We serve Castell 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 sole trader accounts is the same in Castell as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is sole trader accounts in Castell really the same price as elsewhere?
Yes. The fee published on this page is what a client in Castell 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.
