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.

Worth knowing
Rules that come up in this work
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
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.
Dormant companies
Companies formed to protect a name or hold a future business are dormant but not exempt: Companies House still expects dormant accounts within nine months of the year end and a confirmation statement annually with its £50 fee, and HMRC must be told the company is dormant or it will demand Corporation Tax returns. The filings are short, but the penalties for missing them are the same as for a trading company.
The trading and property allowances
Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.
Crypto records and reporting
HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.
The 60-day property CGT return
The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.
Record keeping
Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.
Questions
CIS Tax Returns questions from Merthyr Tydfil
When are contractor returns due?
The CIS300 monthly return covers the tax month to the 5th and must reach HMRC by the 19th. Deduction statements must go to subcontractors by the same date. A nil return is still required if you paid no subcontractors. Late returns cost £100 immediately, rising to £200 after two months and then percentage-based penalties.
What rate do I deduct from a subcontractor?
You must verify each new subcontractor with HMRC before the first payment. HMRC tells you 20% if they are registered, 30% if not, or 0% if they hold gross payment status. Deductions apply to the labour element only, never to materials, VAT or plant hire. We verify every new subcontractor and record the result.
What does the £149 subcontractor return include?
Your full Self Assessment with the self-employment pages, every CIS deduction statement reconciled to your income, allowable expenses claimed, the refund calculated and the return filed. We then track the repayment with HMRC, which usually arrives within two to six weeks of filing in the quieter months.
How much CIS refund can I expect?
It depends on your profit and expenses. Deductions are 20% of the labour element of your invoices; tax is only due on profit after expenses and the £12,570 personal allowance, with Class 4 National Insurance on top. Many subcontractors earning under £35,000 get back several thousand pounds. We give you the figure before filing.
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.
