The headlines
From 2026:
- A new 40% first-year allowance (FYA) for main rate plant and machinery.
- The standard writing-down allowance falls from 18% to 14%.
This changes the pattern of relief on equipment, machinery and some fit-out costs.
What this means for your investment decisions
The Government wants you to invest, but also to smooth tax relief over time.
- You’ll get more relief up front (40%) than under pure writing-down allowances.
- But the remaining value is written down more slowly (14% instead of 18%).
For many small businesses, the Annual Investment Allowance (AIA) will still give 100% relief up to its current limit, but not all spending qualifies or fits neatly into that.
When timing really matters
- If you’re planning a big refit or machinery purchase, the year you incur the cost will affect how quickly the tax relief feeds into your cashflow.
- For companies near key profit thresholds, the pattern of allowances can push you above or below certain tax bands or affect dividend decisions.
Action steps
- Map out major capital spending for the next 3–5 years
Don’t make one-off decisions in isolation. - Ask for a capital allowances forecast
For each major project, have your accountant show the tax relief profile over several years. - Use AIA where it gives a better result
For many SMEs, AIA will remain the main tool, but you need to know when 100% AIA vs 40% FYA + WDAs is best. - Coordinate tax planning with financing
If you’re borrowing for equipment, match loan repayments with the pattern of tax relief to avoid cashflow surprises.
