How we help you navigate Capital Gains Tax
Capital Gains Tax can catch you off guard if you're selling a second property, cashing in investments or disposing of business assets. The rules changed significantly in late 2024, with rates rising from 10% to 18% for basic-rate taxpayers and 20% to 24% for higher earners. We help Cardiff business owners, landlords and individuals understand what they owe, when they need to pay it and how to reduce the bill legally.
Our approach starts with a full review of your situation: what you're selling, when you bought it, what it cost and any improvements you've made. We calculate your gain, apply the annual exempt amount (currently £3,000 for 2025/26) and identify any reliefs you're entitled to, such as Private Residence Relief or Business Asset Disposal Relief. If you're selling property, we'll register you with HMRC if needed and prepare your CGT return within the 60-day deadline. For other assets, we'll include the disposal in your self-assessment return and make sure everything's filed correctly.
We'll help you time your disposal to make the most of allowances and reliefs.

Common concerns we address
Many clients worry they've left planning too late, or that they'll be penalised for mistakes. The truth is, there's often room to manoeuvre even after a sale, and HMRC is more forgiving when you've worked with a professional. We'll handle any correspondence, support you through disputes or investigations and give you peace of mind that your records are accurate. If you're thinking about selling in the future, we can model different scenarios and show you the tax impact of waiting, gifting or transferring assets to a spouse.
Cardiff and South Wales context
We work with clients across Cardiff, the Vale of Glamorgan, Newport and the valleys who are selling buy-to-let properties, downsizing or realising investment gains. Whether you're a Pontcanna landlord, a Penarth retiree or a Caerphilly business owner winding down, we understand the local property market and the practical realities of selling here. Our office is in Cardiff, so we're easy to reach for a face-to-face chat or a quick call when you need clarity.
What happens next
Once we've helped you with a disposal, we stay in touch for future planning. CGT is rarely a one-off event, and the rules keep changing. We'll update you on rate changes, new reliefs and opportunities to restructure your assets. If you're planning further sales or investments, we'll factor CGT into your wider tax strategy so you're never caught out. And if HMRC ever queries your return, we'll deal with them on your behalf.
