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

Changing accountant is simpler than most people fear. You authorise the new firm, which writes to the old one for professional clearance and your records; the outgoing accountant must hand over your own documents and usually does within two weeks. The new firm registers as your agent with HMRC and picks up the next filing. There is no need to wait for a year end.

The 60-day property CGT return

Since April 2020 a gain on UK residential property must be reported and the tax paid within 60 days of completion through HMRC's dedicated service, separately from the annual return. Non-residents must report all UK land disposals in the same window whether or not tax is due. Getting the computation right first time matters because the figure is then carried into the Self Assessment.

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.

Allowable expenses

Expense claims are where a return is won or lost in an enquiry. The test is wholly and exclusively for the trade; where a cost is mixed, the business proportion can be claimed if it can be identified. Capital items such as equipment and vans are relieved through capital allowances rather than as expenses, except under the cash basis where they are simply deducted when paid.

Record keeping

Record keeping is a legal obligation with a penalty of up to £3,000 for failure, but its real value is in making every other filing cheaper and more defensible. Keep invoices, receipts, bank statements, mileage logs and any HMRC correspondence, digitally if you like, for five years after the relevant filing deadline for individuals and six years for companies and VAT.

Workplace pensions and auto-enrolment

Workplace pension compliance is part of payroll, not separate from it. Each pay period the payroll assesses who is eligible, calculates employer and employee contributions on qualifying earnings between the lower and upper thresholds, and sends the contribution file to the scheme. The minimum total is 8%, and many employers choose to contribute more as a recruitment advantage.

Questions

Self Assessment Tax Returns questions from Troed-rhiw'r-fuwch

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.

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.

What records should I keep, and for how long?

Invoices, bank statements, receipts, P60s and P45s, dividend vouchers and any HMRC letters. Keep them for at least five years after the 31 January filing deadline of the tax year they relate to. Photos and PDFs are acceptable to HMRC; paper is not required.

Do you handle Scottish or Welsh income tax?

Yes. Scottish taxpayers have six bands from 19% to 48% and Welsh taxpayers have Welsh rates set by the Senedd, both applied automatically from the residence HMRC holds for you. We check that address is right, because an out-of-date one is a common cause of wrong tax codes.

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.
