1. Scope the job

   We find out what you need filed, when it is due and what state the records are in, and tell you which fixed-fee package applies.

2. Agree the price

   The fee is confirmed in writing. There is no hourly billing and nothing added for questions during the work.

3. Hand over the records

   Photographs, PDFs, software access or a spreadsheet, sent however suits you. We confirm what we have and what is missing within two working days.

4. Approve, then we submit

   You review the draft with our explanation, sign off, and we file. Receipts, copies and the next deadlines come back to you immediately.

Gwaenysgor is in Wales, Wales. Businesses in Wales file with the same HMRC and Companies House as England, and for now the Welsh rates of income tax equal the English ones, though the Senedd can vary them. The practical differences are Land Transaction Tax on property and Welsh-specific business support schemes, and company names and documents may be in Welsh.

CIS deductions

CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.

Confirmation statements and identity verification

The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.

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.

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.

Payments on account

If your Self Assessment bill exceeds £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards the following year, each half of the current bill, due 31 January and 31 July. The first year this happens the January payment is effectively one and a half times the bill. We model it in advance and show you how to reduce the payments if income is falling.

The Self Assessment calendar

Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.

The 60-day property CGT return

Selling UK residential property that was not your main home for the whole period of ownership triggers a separate Capital Gains Tax return, due within 60 days of completion along with payment of the tax. This is in addition to the annual Self Assessment. The gain is taxed at 18% or 24% depending on your income band, after the £3,000 annual exempt amount.
