Why it matters
Miss a deadline once and HMRC remembers every year after.
Sole trader registration, allowable expenses, Class 4 National Insurance and the January balancing payment are not side tasks — they are the rhythm that keeps you trading without penalty letters.
Dinson & Co. exists so freelancers and sole traders in Nottingham and across the UK get accurate figures, on-time filings, and a named accountant who already knows the plan.

Common questions
Self Assessment, explained plainly
Still unsure about deadlines or records? Ask us directly — a clear answer beats another forum thread.
Ask a questionAnyone who is self-employed or a sole trader, a company director, a landlord, or who has untaxed income above certain thresholds generally needs to file a return with HMRC each year.
Paper returns are due by 31 October following the end of the tax year, and online returns by 31 January — the same date your balancing payment is due.
HMRC apply an initial fixed penalty, followed by further daily and percentage-based penalties the longer a return or payment stays outstanding, plus interest on late payments.
Sales invoices, expense receipts, bank statements and records of any other income, kept for at least five years after the filing deadline in case HMRC ask to see them.
Yes — we handle sole trader and self-employment registration with HMRC on your behalf, start to finish.
Let’s get your return filed properly, this year.
