Local facts
About Swansea
Swansea is in Wales, in the SA1 postcode district, 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.

Worth knowing
Rules that come up in this work
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
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
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
Every employer must assess its workers for automatic enrolment from the first employee's start date. Those aged 22 to State Pension age earning over £10,000 a year must be enrolled into a qualifying pension with minimum contributions of 8% of qualifying earnings, at least 3% from the employer, and a declaration of compliance made to the Pensions Regulator within five months.
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.
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.
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.
Questions
Capital Gains Tax questions from Swansea
Do transfers between spouses trigger tax?
No. Transfers between spouses or civil partners living together are at no gain and no loss; the recipient takes over the original cost. This allows both annual exemptions and both basic rate bands to be used on a later sale, which is a common and legitimate way to reduce the tax on a jointly planned disposal.
What if I sell shares from an employee share scheme?
It depends on the scheme. Shares from a SAYE or SIP scheme have specific cost rules and sometimes income tax has already been paid on part of the value. Options exercised and sold on the same day may have no gain at all. We need the scheme documents and the exercise and sale figures, and we apply the correct treatment for each.
What are the Capital Gains Tax rates for 2026/27?
The annual exempt amount is £3,000. Gains above it are taxed at 18% to the extent they fall within your unused basic rate band and 24% above it, for all asset types including residential property. Gains qualifying for business asset disposal relief are taxed at 14% in 2025/26, rising to 18% from April 2026, on up to £1 million of lifetime gains.
What is the 60-day property return?
When a UK resident sells UK residential property and tax is due, they must file a return through HMRC's Capital Gains Tax on UK property service and pay the tax within 60 days of completion. This is separate from and in addition to the annual Self Assessment. Late filing penalties mirror Self Assessment: £100 immediately, then daily and tax-geared penalties.
I sold my former home that I later let out. Is it all taxable?
No. Private residence relief exempts the gain for the period you lived there plus the final nine months of ownership, and certain periods of absence can qualify. The let period is taxable. Lettings relief now applies only where you shared occupation with the tenant. We apportion the gain by days and claim every qualifying period.
What costs can I deduct from the gain?
The purchase price, stamp duty and legal fees on purchase, capital improvements that are still reflected in the asset at sale (extensions, new kitchens, not repairs), and selling costs including agent and legal fees. For shares, dealing costs and stamp duty. For inherited assets, the probate value is the cost.
