Reliefs and timing
A property CGT accountant calculates the gain after acquisition costs, improvements and selling costs, applies private residence relief where it is due, and files the sixty day UK property return and payment on time.
Disposals of UK residential property that produce a taxable gain must be reported and the tax paid within sixty days of completion, separately from the Self Assessment return. Late filing brings penalties and interest, and the deadline catches many sellers who expect to deal with it at the year end.
The gain is proceeds less purchase price, purchase SDLT and legal fees, capital improvements, and selling costs including agent and legal fees. Improvements are the commonly missed item, particularly extensions or conversions carried out years earlier. Finding those records is often worth thousands.
Private residence relief covers periods the property was your main home plus the final period of ownership. Transfers between spouses are at no gain no loss, which can use two annual exemptions and two sets of basic rate band. Timing a disposal across a tax year can also matter where income fluctuates.
Rates, thresholds and deadlines quoted here reflect the current UK position and current HMRC and Companies House guidance. Check GOV.UK, or ask us, before relying on them for your own business.

Frequently asked
For UK residents with no tax due, usually no separate sixty day return. Non residents must report regardless.
Only in restricted circumstances where you shared occupancy with the tenant.
Residential property gains are taxed at the residential rates depending on your income band for the year.
The answer depends on financing, existing gains, income tax rates, extraction plans and long-term ownership. Moving an existing property can trigger tax and legal costs, so compare the full life-cycle position before changing ownership.
Repairs that restore an asset are commonly revenue costs, while improvements and acquisition costs are usually capital. The distinction affects current tax relief and the gain on a later sale, so invoices should describe the work clearly.
Keep bank statements, sales and platform reports, purchase invoices, payroll records, VAT workings, finance agreements and Companies House correspondence. We confirm the exact list at onboarding and identify gaps before a filing deadline becomes urgent.
The fee depends on transaction volume, record quality, VAT and payroll requirements, historic catch-up and the level of reporting needed. We agree a fixed scope and price before technical work starts, with published packages available on our fees page.

“We worked with a few different accountants before finally settling with Accotax, and we're really glad we did. They take the time to understand how our business works and what our needs are. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing, professional, efficient, and follows the processes we have put in place together. Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.”
