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.
Late filing penalties
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
Making Tax Digital for Income Tax
Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.
The Self Assessment calendar
Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.
Payments on account
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
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
CIS Tax Returns questions from Guildhall
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.
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.

No. IGI Accounting is an online-only firm. We serve Guildhall, City of London and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically.
