Tax Relief on Business Assets (AIA)
We help small businesses across Cardiff and South Wales claim the tax relief they're entitled to on equipment and machinery, often saving thousands on their next bill. Our team makes sure you get every penny of Annual Investment Allowance you qualify for, with none of the confusion.

Making the most of your investment
Annual Investment Allowance is just one way to reduce your tax bill when you invest in your business. We'll help you find every relief and allowance that applies to your situation.
Plant and Machinery Claims
Full relief on production equipment, tools, and commercial vehicles bought for your business.
IT and Office Equipment
Immediate deductions on computers, servers, desks, and everything else that keeps your office running.
Capital Allowances Planning
Strategic advice on timing purchases to maximise relief across accounting periods.
Writing Down Allowances
Tax relief on spending over the £1 million AIA limit, claimed at 18% or 6% per year.
How we help you claim Annual Investment Allowance
Annual Investment Allowance lets you deduct the full cost of qualifying business assets from your taxable profits in the year you buy them, up to £1 million per accounting period. That means if you spend £50,000 on a new van, machinery, or IT equipment, you can knock £50,000 off your profit before tax. We make sure you claim everything you're entitled to, whether you're a sole trader buying your first work vehicle or a growing company kitting out a new workshop.
The process starts with a conversation about what you've bought or plan to buy. We check which items qualify (most plant, machinery, commercial vehicles, and office equipment do), record them correctly in your accounts, and claim the relief in your Corporation Tax or Self-Assessment return. You'll need to keep your invoices for at least six years, and we'll flag anything that doesn't qualify, like cars or assets you use personally.
Most of our Cardiff clients don't realise how much tax relief is sitting in their recent purchases until we review their accounts.
More information
Common concerns include whether second-hand equipment qualifies (it does, as long as it's for business use) and what happens if you later sell an asset you've claimed for (you may owe some tax back on the proceeds). If your spending exceeds the £1 million limit, we'll apply Writing Down Allowances to the excess at 18% or 6% per year, depending on the asset type. We also check whether you can combine AIA with other reliefs like First-Year Allowances for energy-efficient kit.
What's included
- Review of all asset purchases in your accounting period
- Identification of qualifying plant, machinery, and equipment
- Accurate claim preparation in your tax return
- Advice on timing purchases to maximise relief
- Guidance on record-keeping and HMRC compliance
We work with tradespeople, retailers, salons, and small manufacturers right across South Wales, from Pontypridd to Newport. Many of our clients are at the stage where they're reinvesting profits into better equipment or a bigger premises, and AIA can make a real dent in the tax bill that comes with growth. Whether you're based in Riverside, Roath, or further out in the Valleys, we'll make sure your investment works as hard as possible.
If you've bought qualifying assets in the past year and haven't claimed AIA yet, it's not too late. Get in touch and we'll review your accounts to see what relief you're owed.
