Tax Relief and Agricultural Equipment Finance
The tax treatment of agricultural finance is a critical factor in choosing between HP, finance lease and operating lease - and often makes a significant difference to the total net cost of an investment. Understanding the interaction between AIA, full expensing, writing-down allowances, and the deductibility of finance charges can reduce the effective cost of a major equipment purchase by tens of thousands of pounds.
The information below is a general guide. Always take specific tax advice from your accountant before making a major finance decision.
Tax Treatment by Finance Type
| Finance Type | Capital Allowances | Revenue Deduction | VAT Recovery |
|---|---|---|---|
| Hire Purchase (HP) | AIA in year 1 (up to £1m) or WDA 18% p.a. | Interest element only | Full VAT at inception |
| Finance Lease | Lender claims - not the farmer | Full rental deductible | VAT on each rental |
| Operating Lease | Lender claims | Full rental deductible | VAT on each rental |
| Full Expensing (Ltd Co, new assets) | 100% in year 1 - no limit | Interest only (on HP) | Full VAT at inception |
Annual Investment Allowance - How It Works
The AIA provides 100% first-year tax relief against trading income for qualifying plant and machinery purchases. For a limited company paying 25% corporation tax, a £200,000 tractor purchased on HP with AIA generates a £50,000 tax saving in year one - partially offsetting the finance cost immediately.
Key points about AIA for agricultural businesses:
- Current AIA limit: £1 million per annum (as at October 2026)
- Applies to new and used assets
- Available to sole traders, partnerships and limited companies
- Cannot be claimed on leased assets where the lender retains legal ownership
- Where AIA limit is exceeded, Writing Down Allowances (WDA) of 18% per annum apply
Full Expensing for Limited Company Farmers
Since April 2023, UK limited companies can claim 100% first-year allowance on qualifying new plant and machinery with no upper limit. This supersedes AIA for limited companies investing heavily in new equipment. Used equipment is excluded - AIA remains the relief for second-hand purchases.
