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
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.
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.
The 60-day property CGT return
Since April 2020 a gain on UK residential property must be reported and the tax paid within 60 days of completion through HMRC's dedicated service, separately from the annual return. Non-residents must report all UK land disposals in the same window whether or not tax is due. Getting the computation right first time matters because the figure is then carried into the Self Assessment.
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.
Allowable expenses
Expense claims are where a return is won or lost in an enquiry. The test is wholly and exclusively for the trade; where a cost is mixed, the business proportion can be claimed if it can be identified. Capital items such as equipment and vans are relieved through capital allowances rather than as expenses, except under the cash basis where they are simply deducted when paid.
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.
Questions
CIS Tax Returns questions from Deptford
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 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.
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.
Do you have an office in Deptford?
No. IGI Accounting is an online-only firm. We serve Deptford, Greenwich 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 Deptford as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is cis tax returns in Deptford really the same price as elsewhere?
Yes. The fee published on this page is what a client in Deptford, Greenwich 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.
