Can I switch to a limited company later?
Yes. If you start out with us as a sole trader, you can change to a limited company later down the line. This is also known as incorporating. We’ll help you complete the admin and notify Companies House when you’re ready to make the switch and adapt our services as you evolve. If your net profits are consistently above £50,000, incorporating may reduce your tax bill by up to £6,000 a year. We advise on timing based on your forecast, pension goals, and reinvestment plans.
Common reasons for incorporating:
– Protecting personal assets by limiting liabilities.
– Saving around 6k in tax if annual net profits exceed 50k.
– Tax planning with pensions, dividends & investments.
As you grow and when the time is right, we’ll also advise you whether incorporating is the right move.

Sole traders in Cardiff, Newport and Bristol
A sole trader's year has four moments that matter, and three of them are dates. Registering on time, knowing which year of income drags you into Making Tax Digital, filing and paying by 31 January, and keeping the payments on account from becoming a surprise. Everything else is bookkeeping.
The local part is narrower than people expect. If you live in Wales you are a Welsh taxpayer, HMRC puts a C at the front of your code, and for 2026 to 2027 the Welsh bands are the same as England and Northern Ireland. Trading in Bristol while living in Newport does not make you an English taxpayer. Where your main home sat across the tax year does.
The threshold that decides whether you file at all. Gross trading income over £1,000 in the tax year, before any expenses, means a return. The government has announced an intention to lift that to £3,000 within this Parliament, with no commencement date published, so £1,000 is the live figure for 2025 to 2026 and 2026 to 2027.
The Making Tax Digital timetable, as legislated
- Already live. Qualifying income over £50,000 in 2024 to 2025, mandatory from 6 April 2026. Quarterly updates began, with the first deadline on 7 August 2026.
- From 6 April 2027. Qualifying income over £30,000 in 2025 to 2026.
- From 6 April 2028. Qualifying income over £20,000 in 2026 to 2027.
- None of it changes the 2025 to 2026 return or the 31 January 2027 deadline.

What a sole trader accountant costsCommon questions
Do I have to register for Self Assessment as a sole trader?
If your gross trading income was more than £1,000 in the tax year, before expenses, yes. The registration deadline is 5 October following the end of that tax year. Miss it and HMRC sets your filing deadline three months from the date on its letter instead of 31 January, and a failure to notify penalty comes into play.
When does Making Tax Digital actually hit me?
It depends on your qualifying income in the year HMRC tests. Over £50,000 in 2024 to 2025 means you should already be in, from 6 April 2026. Over £30,000 in 2025 to 2026 brings you in from 6 April 2027. Over £20,000 in 2026 to 2027 brings you in from 6 April 2028. None of that changes the 31 January 2027 filing.
Why am I being asked for a payment on account?
Because last year's Self Assessment bill was £1,000 or more and less than 80 per cent of your tax was already collected at source. Each instalment is normally half of last year's bill, due 31 January and 31 July. You can ask HMRC to reduce them if you expect to earn less, but if the real bill comes in higher, HMRC charges interest on the difference.
I trade in Newport but most of my work is in Bristol. Which rates apply?
Your main home decides it, not where the work is. If you live in Wales you are a Welsh taxpayer with a C prefix code, whatever side of the border your customers are on. For 2026 to 2027 the Welsh bands match England, so the figure does not change, but the code on HMRC's record needs to be right.
Bring us last year's figures and we will tell you what you owe, when, and whether Making Tax Digital reaches you before it reaches your neighbour.
