Wern-y-cwrt is in Wales, Wales. Welsh taxpayers pay Welsh rates of income tax, set by the Senedd and currently matching the English bands, collected under a C-prefixed tax code. National Insurance, VAT and Corporation Tax are UK-wide. Property purchases in Wales pay Land Transaction Tax to the Welsh Revenue Authority rather than Stamp Duty, with its own bands and rates.

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.

CIS deductions

Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.

Late filing penalties

HMRC's penalties for a late Self Assessment return are automatic: £100 the day after 31 January, £10 a day from three months late up to £900, then the greater of £300 or 5% of the tax at six and twelve months. Interest and separate late-payment penalties apply to the tax itself. Companies House charges £150 to £1,500 for late accounts, doubling for a second consecutive year.

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

The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.

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.

Salary versus dividends

Paying yourself from a company involves two routes with different tax treatment. Salary through payroll is a company expense and builds a National Insurance record; dividends come from post-tax profit at lower personal rates. Undocumented drawings that are neither become director's loans, with a 35.75% section 455 charge if not repaid within nine months of the year end.
