Capital Allowances Before You Pay

Here's something most construction business owners don't know: you can claim tax relief on equipment before you've finished paying for it.
Sounds too good to be true? It's not - but only if you understand the timing rules.
The way capital allowances work with delayed payments and hire purchase agreements can either save you thousands in tax this year, or accidentally push your relief into next year.
Let me show you how to make the timing work in your favour.
Understanding Capital Allowances Timing
Right now, tax relief on equipment purchases is extremely generous:
Annual Investment Allowance (AIA): Up to £1 million in tax relief per year
Full Expensing: Unlimited relief for companies on qualifying equipment
100% first-year relief on many items
But here's the catch: when you get that relief depends on your payment timing.
Get it right, and you claim relief this year on equipment you won't finish paying for until next year.
Get it wrong, and you wait an extra 12 months for relief you could have claimed already.
For construction businesses buying excavators, vans, tools, or site equipment, this timing can make a £20,000+ difference to your tax bill.

Hire Purchase Capital Allowances Rules
When you buy equipment on hire purchase (HP), special timing rules apply that work in your favour.
Here's how it works:
Deposit payment - Gets capital allowances relief in the year you pay it
Future payments - Get relief in the year the equipment starts being used in your business
Interest/hire charges - Claimed separately as they're paid
This means you can claim 100% tax relief on the full purchase price in year one, even though you're paying it off over several years.
Pro tip: When signing HP agreements near your year end, ensure delivery is scheduled with enough time for installation and first use before year end. This accelerates your tax relief by a full year.

The Four-Month Payment Trap
Here's where many businesses accidentally delay their capital allowances by a full year.
The rule: If your purchase contract allows payment more than four months after the agreement becomes binding, you can only claim capital allowances in the year you actually make the payments.
This only matters if the purchase and payment dates fall either side of your year end - but when it does matter, it's costly.
Capital Allowances Timing Checklist
Before making equipment purchases, ask yourself:
✓ When does my financial year end?
✓ When will the equipment be delivered?
✓ When will it first be used in the business?
✓ What are the payment terms - within or beyond four months?
✓ Am I using hire purchase, and if so, when does the agreement start?
✓ Could I negotiate different payment terms to optimize capital allowances timing?
✓ Would delaying the purchase by a few weeks or months improve my tax position?
For hire purchase specifically:
✓ Can the equipment be delivered and used before my year end?
✓ Have I claimed capital allowances on the deposit in the year paid?
✓ Am I treating hire charges separately from capital payments in my accounts?
Common Capital Allowances Timing Mistakes
Assuming Payment Date = Relief Date
Wrong thinking: "I paid for it in March 2027, so I'll claim relief in my 2027 accounts."
Reality: If you signed the contract in November 2026 with payment due within four months, you can claim relief in your 2026 accounts even though you paid in 2027.
Missing the HP Advantage
Wrong thinking: "I'll wait until I've paid off the HP before claiming full capital allowances."
Reality: You claim the full capital balance in the year the equipment starts being used, regardless of future payment dates.
Ignoring Year-End Timing
Wrong thinking: "I'll order this in December; it doesn't matter when it arrives."
Reality: If your year ends 31 December and delivery happens 2 January, you've just delayed your relief by 12 months.

Making Capital Allowances Timing Work
The difference between claiming capital allowances this year versus next year could mean:
£25,000 tax relief claimed 12 months earlier
£6,250 cash (at 25% Corporation Tax) available sooner for reinvestment
Better cash flow when you need it most
Three key takeaways:
Hire purchase timing rules favour early relief - you claim the full amount when equipment is first used, not when you've finished paying
The four-month payment rule can trap you - if payment can be made more than four months after contract signing, relief is delayed to when you actually pay
Delivery and first use dates matter - equipment must be in use before year end to claim relief that year
Planning a major equipment purchase?
Before you sign anything, understand how the timing will affect your capital allowances claim. A conversation with your accountant before the contract is signed could save you thousands in delayed tax relief.
