Explore the UK's new 40% plant and machinery tax relief for 2026, how it affects investment decisions, and what it means for plant equipment traders and buyers.
Government Introduces New 40% First-Year Tax Relief on Plant & Machinery
A new 40% tax relief for plant and machinery investment came into force on 1 January 2026, offering businesses a powerful incentive to invest in essential equipment. This change is part of the UK government's ongoing drive to boost business investment and support economic growth.
Under the updated tax regime, eligible businesses can now claim a 40% First-Year Allowance (FYA) on qualifying plant and machinery purchases in the first year — reducing taxable profits and lowering overall tax bills for 2026 and beyond.
This new relief replaces part of the previous "full expensing" rules and expands the benefit to a broader group of businesses, including those buying equipment for leasing or operating as unincorporated entities.
What Counts as Plant & Machinery for Tax Relief?
In tax terms, plant and machinery refers to tangible assets used in the operation of a business, excluding land and buildings. Examples include:
- Construction plant like excavators, bulldozers, and cranes
- Industrial equipment and tools
- Office machinery and IT systems necessary for operations
- Warehouse handling equipment
- Lease-eligible assets used in plant hire businesses
This broad definition means that many purchases you make across your business — from key construction assets to essential tools — may now qualify for immediate tax relief through the new allowance.
How the New Tax Relief Benefits Your Plant Machinery Investments
Immediate Tax Savings
Businesses can write off 40% of qualifying plant and machinery costs in the first year, significantly reducing taxable profit and freeing up cash flow for reinvestment. This makes new equipment purchases more affordable and can help upgrade ageing fleets.
Relief Extended to More Businesses
Previously, full expensing (100% first-year relief) was limited mainly to companies. The new 40% FYA expands eligibility to:
- Unincorporated businesses (sole traders, partnerships)
- Plant hire and leasing companies
- Businesses that did not previously qualify for full expensing
What's Changing in April 2026
From April 2026, main rate Writing Down Allowances (WDAs) — the standard method for deducting plant and machinery value over time — will be reduced from 18% to 14%. This change makes the upfront 40% FYA even more valuable for qualifying investments made before or during early 2026.
