Worth knowing
Rules that come up in this work
Dormant companies
Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.
The trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Employer National Insurance
The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.
Workplace pensions and auto-enrolment
Every employer must assess its workers for automatic enrolment from the first employee's start date. Those aged 22 to State Pension age earning over £10,000 a year must be enrolled into a qualifying pension with minimum contributions of 8% of qualifying earnings, at least 3% from the employer, and a declaration of compliance made to the Pensions Regulator within five months.
Switching accountants
You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.
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.
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.
Questions
Self Assessment Tax Returns questions from Holborn and Covent Garden
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.
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.
How quickly can you file once I send my records?
Most straightforward returns are drafted within five working days of receiving complete records and filed the day you approve. In January we prioritise by deadline risk and tell you your slot when you book, so late bookers are not left guessing.
I have never filed before. Do I need a UTR first?
Yes. If you have not registered we handle the registration as part of the job and HMRC posts your Unique Taxpayer Reference within about ten working days. Start early if your first deadline is close, because HMRC will not accept a return without it.
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 Holborn and Covent Garden 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.
