What Is the Annual Investment Allowance (AIA) for Dentists?
The Annual Investment Allowance (AIA) is a UK tax relief that allows dental practices to deduct the full cost of qualifying business assets — up to £1 million per year — from their taxable profits.
This means that instead of spreading deductions over several years, practices can claim 100% tax relief in the year the asset is purchased.
Why Does the AIA Matter for Dental Practice Owners?
Dentistry is equipment-heavy — chairs, CBCT scanners, digital imaging, and IT systems require significant investment. The AIA helps owners:
- Reduce their Corporation Tax bill immediately
- Improve cash flow by accelerating tax relief
- Justify reinvestment in new surgeries, technology, or refurbishments
Example:
- CBCT scanner purchased for £25,000
- Claimed under AIA = £25,000 deducted from profit
- Tax saving at 19% = £4,750
- Net cost to practice = £20,250
What Assets Qualify for the AIA in Dental Practices?
| Asset Type | Examples |
| Dental Equipment | Chairs, delivery units, surgery lights |
| Technology | Digital X-ray, CBCT, scanners, IT servers |
| Refurbishment | Built-in cabinetry, surgery fit-outs |
| Software | Practice management or imaging systems |
| Vehicles | Business-use vehicles (restrictions apply) |
Note: Land, buildings, and assets with private use do not qualify.
