Local facts

About Ynys-fach

Ynys-fach 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.

Worth knowing

Rules that come up in this work

Employer National Insurance

The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.

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.

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

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.

Questions

Corporation Tax questions from Ynys-fach

Does R&D affect my Corporation Tax return?

Yes. Research and development relief is claimed on the CT600 and reduces the tax or generates a credit. Since the merged scheme, first-time claimants must notify HMRC within six months of the period end. Our R&D service prepares the technical report and the computation; the claim then goes on the return we file.

Can you deal with HMRC if they open an enquiry into the return?

Yes. As your authorised agent we receive and respond to HMRC correspondence. Routine queries about a return we filed are handled at no extra charge. A formal enquiry is handled through our HMRC investigation service at fixed fees per stage, so you know the cost before deciding how to proceed.

What expenses are not allowed for Corporation Tax?

Business entertainment of customers, most fines and penalties, depreciation (replaced by capital allowances), general provisions, and the private element of mixed-use costs. Legal fees on capital items are also disallowed. The computation adds these back to accounting profit and we list every adjustment so you can see the effect.

Are dividends and salary treated differently for Corporation Tax?

Yes. Salary, employer National Insurance and employer pension contributions are deductible expenses that reduce taxable profit. Dividends are paid from profit after tax and are not deductible. This asymmetry is central to the salary-versus-dividend planning we do for directors.

What are associated companies and why do they matter?

Companies under common control count as associated, and the £50,000 and £250,000 thresholds are divided between them. A director who owns two companies has thresholds of £25,000 and £125,000 for each. Missing this is a common error that produces an underpayment and interest.

My company made a loss. What can be done with it?

A trading loss can be set against the company's other profits of the same year, carried back one year for a repayment of tax already paid, or carried forward against future profits. The right choice depends on cash flow and expected profits. We model the options and make the claim on the return.
