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.

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.

Employer National Insurance

Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.

The trading and property allowances

Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.

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 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.

Questions

Contractor Accountants questions from Portsoken

What happens between contracts?

The company continues and so do the filings, but we can reduce the salary and pause dividends. If you expect a long gap we discuss whether to keep the company trading, make it dormant or close it. The monthly fee continues while the company is active because the compliance does, but we review it with you if circumstances change.

Can the company pay into my pension?

Yes, and it is one of the most efficient ways to extract value. Employer pension contributions are deductible for Corporation Tax, free of National Insurance and not taxed on you, up to the £60,000 annual allowance (tapered for very high earners). We include pension planning in the Complete package's annual call.

What is IR35 and does it affect me?

IR35 asks whether, but for the company, you would be an employee of your client. If a contract is inside IR35 the income is taxed like employment. Since 2021 medium and large private-sector clients make the determination and deduct tax at source; for small clients the contractor decides. We review contracts and working practices and give a written opinion for £99.

How should I pay myself from the company?

The usual approach is a salary around the National Insurance thresholds, which keeps your State Pension record intact and is deductible for Corporation Tax, with the rest as dividends taxed at the dividend rates after the £500 allowance. The exact split depends on your other income and the company's profit, and we set it at the start of each tax year.

What do Plus and Complete add?

Plus at £105 adds quarterly VAT returns and monthly bookkeeping from your bank feed, so the records are kept for you. Complete at £125 adds the director's Self Assessment return and an annual tax planning call covering salary, dividends, pension and the year ahead. Most contractors inside VAT choose Plus or Complete.

What is in the £75 Essential package?

Annual statutory accounts and CT600 filed with Companies House and HMRC, monthly director payroll with RTI submissions, dividend vouchers and minutes, the confirmation statement filed (Companies House £50 fee separate), and deadline tracking. It suits contractors outside VAT or who prefer to do their own VAT and bookkeeping.
