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
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.
Employer National Insurance
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
Record keeping
Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.
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
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.
Questions
Contractor Accountants questions from Southfields
I am about to leave permanent employment to contract. Where do I start?
With the company formation and the first contract review. Our £99 formation-plus-registrations package sets up the company with Corporation Tax and PAYE registered; the IR35 review of your first engagement decides how the income will be taxed. Join the Essential package from the month you start invoicing.
Do I need business insurance?
Most client contracts require professional indemnity and public liability cover, and employer's liability is a legal requirement if the company employs anyone other than the director. Insurance is not something we sell, but we tell you what your contracts require and the premiums are deductible for Corporation Tax.
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 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.
My client has put me inside IR35. Should I still use my company?
It can still be worth it if you have other outside-IR35 work, but for a single inside-IR35 engagement an umbrella company or direct PAYE is often simpler and cheaper. We run the comparison for your specific numbers and tell you honestly, even if the answer is that you do not need us for that contract.
Can I claim travel and subsistence?
For engagements outside IR35, travel to a client site that is a temporary workplace is claimable, subject to the 24-month rule: once you know an engagement will exceed 24 months at the same site, it stops being temporary. Subsistence follows the travel. Inside-IR35 engagements lose these claims. We check each engagement.
