Worth knowing
Rules that affect most businesses here
CIS deductions
The Construction Industry Scheme affects both sides of a construction payment. Contractors must verify subcontractors, deduct the right amount, issue statements and file monthly, with penalties from £100 for each late return. Subcontractors suffer deductions on turnover and recover the excess at the year end. Limited company subcontractors offset deductions against PAYE monthly instead.
Confirmation statements and identity verification
Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition year.
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.
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.
Workplace pensions and auto-enrolment
Workplace pension compliance is part of payroll, not separate from it. Each pay period the payroll assesses who is eligible, calculates employer and employee contributions on qualifying earnings between the lower and upper thresholds, and sends the contribution file to the scheme. The minimum total is 8%, and many employers choose to contribute more as a recruitment advantage.
Questions
Questions from Windsor Great Park
Why are the fees the same in Windsor Great Park as in London?
Because the cost of an accountant is mostly premises and that is a cost we do not have. The work is done online by UK-based staff, so a client in Windsor Great Park pays exactly the published fee, as does a client in central London or a Highland village. The fee is confirmed in writing before anything starts.
Which services are available in Windsor Great Park?
Every service on this page is available to businesses and individuals in Windsor Great Park, at the fee shown. Core compliance work, accounts, tax returns, bookkeeping, VAT, payroll and company formation, is listed with its own local page. Specialist services such as R&D, crypto tax and HMRC enquiry support are national services delivered the same way from anywhere in the UK.
I already have an accountant in Windsor Great Park. How hard is it to switch?
It takes about two weeks and costs nothing extra. You authorise us, we write to your current accountant for professional clearance and your records, and we transfer the agent authorisations. We pick up the next filing without a gap. You do not need to wait for a year end, and we tell you honestly if switching mid-job would be awkward.
Can you deal with HMRC and Companies House for me?
Yes. Once you authorise us as your agent, HMRC and Companies House correspond with us about the filings we make for your Windsor Great Park business, and we can see your accounts and respond on your behalf. Authorisation is free and takes a few days to activate. Routine correspondence about work we have filed is handled at no extra charge.
Is self assessment tax returns in Windsor Great Park really the same price as elsewhere?
Yes. The fee published on this page is what a client in Windsor Great Park 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.
Do you have an office in Windsor Great Park?
No. IGI Accounting is an online-only firm. We serve Windsor Great Park 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 self assessment tax returns is the same in Windsor Great Park as anywhere else in the country, and why there is nothing to visit and nothing to print.
