Worth knowing
Rules that come up in this work
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.
Closing a company
Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.
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.
Allowable expenses
An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.
Crypto records and reporting
Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.
The 60-day property CGT return
The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.
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.
Questions
Self Assessment Tax Returns questions from Sulham
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.
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.
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.
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.
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.
What does the £129 return cover?
A full SA100 with the supplementary pages for one income source, prepared, checked and filed online. Rental income, capital gains or several income sources move you to the £169 or £199 package, and we tell you which applies before we start, never on the invoice.
Which deadlines matter most for self assessment tax returns?
The next four dates that apply to self assessment tax returns are shown at the top of this page, calculated from today. For Sulham 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.
