Worth knowing
Rules that come up in this work
Switching accountants
The main reasons people switch accountant are surprise invoices, missed deadlines and not understanding what they are being told. Switching involves a clearance letter between the firms, a transfer of records and agent authorisations, and a short handover of the current position. It takes about two weeks and should cost nothing extra.
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.
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.
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
HMRC requires records of all income and expenses, bank statements, invoices and receipts to be kept for at least five years after the 31 January filing deadline of the tax year they relate to, and companies must keep records for six years from the end of the accounting period. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software.
Questions
CIS Tax Returns questions from Greenwich West
Can my CIS deductions be set against my VAT or other taxes?
For sole traders, no; CIS deductions are credited against your income tax and Class 4 National Insurance through Self Assessment, with the excess refunded. For companies, deductions are offset against PAYE and CIS owed, and the remaining balance is repaid by HMRC after the year end or, on request, set against Corporation Tax.
I have not filed for several years. Can you catch me up?
Yes. Late Self Assessment returns can be filed for the last four tax years to reclaim CIS deductions, and HMRC will offset refunds against any penalties. We quote a fixed fee for the set based on the number of years and reconcile each year's statements. The sooner this is done the more years remain claimable.
What is gross payment status and can I get it?
Gross status means contractors pay you in full with no deduction; you pay your tax through Self Assessment or Corporation Tax instead. You need a construction turnover of at least £30,000 (sole trader) or £30,000 per director for companies, a clean compliance record for the previous 12 months and a UK bank account. Our £199 service prepares and submits the application.
How does CIS work for a limited company subcontractor?
Deductions suffered by a company are not reclaimed through Self Assessment. They are offset against the company's own PAYE and CIS liabilities each month through the Employer Payment Summary, and any excess at the year end is reclaimed from HMRC in writing. The £49 CIS plus payroll bundle handles this monthly.
How does the VAT reverse charge affect CIS work?
Since March 2021, where both parties are VAT and CIS registered and the supply is within the scheme, the subcontractor does not charge VAT; the contractor accounts for it on their own return. The invoice must state that the reverse charge applies. We check your sales and purchase invoices for this on every return.
Do I need to register for CIS?
Subcontractors should register so deductions are 20% rather than 30%; registration is free with HMRC or £49 through our service with your UTR sorted at the same time. Contractors must register before paying their first subcontractor. If you are both, both registrations are needed; our dual package is £99.
