Local facts
About Cellan
Cellan is in Wales, 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
CIS deductions
The Construction Industry Scheme affects both sides of a construction payment. Contractors must verify subcontractors, deduct the right amount, issue statements and file monthly, with penalties from £100 for each late return. Subcontractors suffer deductions on turnover and recover the excess at the year end. Limited company subcontractors offset deductions against PAYE monthly instead.
Confirmation statements and identity verification
The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.
Payments on account
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
The Self Assessment calendar
Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.
Making Tax Digital for Income Tax
The biggest change to Self Assessment in a generation is Making Tax Digital for Income Tax, now live for higher-earning sole traders and landlords and arriving for the rest in stages. Quarterly updates are due by 7 August, 7 November, 7 February and 7 May, built from digital records. The practical consequence is that spreadsheet-and-shoebox bookkeeping is ending for anyone above the threshold.
Late filing penalties
HMRC's penalties for a late Self Assessment return are automatic: £100 the day after 31 January, £10 a day from three months late up to £900, then the greater of £300 or 5% of the tax at six and twelve months. Interest and separate late-payment penalties apply to the tax itself. Companies House charges £150 to £1,500 for late accounts, doubling for a second consecutive year.
Corporation Tax rates and marginal relief
Corporation Tax is not a flat rate. Profits to £50,000 pay 19%, profits above £250,000 pay 25%, and the band between is taxed at an effective marginal rate of 26.5% through the marginal relief mechanism. Associated companies share the thresholds, which catches directors who own more than one company and is the most common cause of underpaid tax in owner-managed groups.
Questions
Sole Trader Accounts questions from Cellan
Can you deal with my previous accountant?
Yes. Once you authorise us we write for professional clearance and your records, including the previous year's accounts and capital allowance pools, which we need for continuity. Most firms respond within two weeks and nothing about switching changes our fee.
What if HMRC checks my return?
HMRC can enquire into a return within twelve months of filing, and longer if something was omitted. Well-prepared accounts with organised records are the best protection. If an enquiry opens, routine correspondence about a return we filed is handled free, and formal enquiries go through our fixed-fee investigation service.
Should I become a limited company?
It depends on profit level, how much you need to draw, liability exposure and whether you want to retain profits. At modest profits the saving is small after the extra compliance cost; at higher profits incorporation can help. Our free comparison tool gives a first view and the tax planning review gives a definitive one.
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.
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.
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.
How do I get started from Cellan?
Message us on WhatsApp or email with a sentence about your business and what you need. We reply in working hours with any questions and a fixed fee for sole trader accounts. Once you confirm, we tell you exactly which records to send and the work begins. Most Cellan clients are set up within a day.
Which deadlines matter most for sole trader accounts?
The next four dates that apply to sole trader accounts are shown at the top of this page, calculated from today. For Cellan clients we diarise every one of them from the day you join and send reminders before each, so the work is done in good time rather than in the last week before a penalty.
