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
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.
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.
Dormant companies
Companies formed to protect a name or hold a future business are dormant but not exempt: Companies House still expects dormant accounts within nine months of the year end and a confirmation statement annually with its £50 fee, and HMRC must be told the company is dormant or it will demand Corporation Tax returns. The filings are short, but the penalties for missing them are the same as for a trading company.
The trading and property allowances
Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.
Crypto records and reporting
HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.
Questions
CIS Tax Returns questions from Mitcham Eastfields
What counts as construction work under CIS?
Site preparation, building, alteration, repair, decoration, demolition, and installing systems such as heating, lighting and water. Professional work such as architecture and surveying, scaffolding hire without labour, and carpet fitting are outside the scheme. Mixed contracts fall within it entirely. We check borderline cases against HMRC's list.
What records do I need to keep for CIS?
Subcontractors: every deduction statement, invoices and bank records. Contractors: verification references, gross payments, materials costs, deductions made and the statements issued, for at least three years. Missing deduction statements are the most common reason refunds are delayed, so we help you obtain copies from contractors.
When are contractor returns due?
The CIS300 monthly return covers the tax month to the 5th and must reach HMRC by the 19th. Deduction statements must go to subcontractors by the same date. A nil return is still required if you paid no subcontractors. Late returns cost £100 immediately, rising to £200 after two months and then percentage-based penalties.
What rate do I deduct from a subcontractor?
You must verify each new subcontractor with HMRC before the first payment. HMRC tells you 20% if they are registered, 30% if not, or 0% if they hold gross payment status. Deductions apply to the labour element only, never to materials, VAT or plant hire. We verify every new subcontractor and record the result.
What does the £149 subcontractor return include?
Your full Self Assessment with the self-employment pages, every CIS deduction statement reconciled to your income, allowable expenses claimed, the refund calculated and the return filed. We then track the repayment with HMRC, which usually arrives within two to six weeks of filing in the quieter months.
How much CIS refund can I expect?
It depends on your profit and expenses. Deductions are 20% of the labour element of your invoices; tax is only due on profit after expenses and the £12,570 personal allowance, with Class 4 National Insurance on top. Many subcontractors earning under £35,000 get back several thousand pounds. We give you the figure before filing.
Do you have an office in Mitcham Eastfields?
No. IGI Accounting is an online-only firm. We serve Mitcham Eastfields and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for cis tax returns is the same in Mitcham Eastfields as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is cis tax returns in Mitcham Eastfields really the same price as elsewhere?
Yes. The fee published on this page is what a client in Mitcham Eastfields pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
