Buy vs Lease for Business Equipment: Tax and Cash Flow

When you're deciding whether to buy or lease business equipment, the numbers matter — but so does the tax treatment. This guide breaks down the tax implications of buying vs leasing business equipment, shows you how capital allowances work, and gives you a framework to calculate which option saves your business the most money.

Buy vs Lease: Understanding the Tax Difference

When you buy business equipment, the Inland Revenue treats it differently than when you lease. The key difference is capital allowances.

If you buy a piece of equipment — a delivery van, manufacturing machinery, office furniture, or IT hardware — you can claim capital allowances against your business profits. This is a tax relief that reduces your taxable income. You don't claim the full cost in year one; instead, you claim an annual allowance (usually 18% of the reducing balance, with some assets getting 50% in year one under the "super-deduction" rules).

If you lease the same equipment, there's no capital allowance. Instead, the lease payment itself is a business expense — it's deductible directly from your business profits, like rent or wages. You get the relief year by year as you pay the lease, rather than as a capital deduction upfront.

Sounds like buying is always better? Not necessarily. It depends on your cash flow, tax rate, and how quickly you need the relief.

How Capital Allowances Work: A Real Example

Let's walk through the maths with a real scenario.

Imagine you're a plumbing contractor buying a new van. You buy it for £25,000.

Under current rules, your first-year capital allowance (FYA) on equipment like this is usually 18% per year on a reducing balance. (Some equipment might qualify for the 50% super-deduction, but let's assume you use the standard 18% writing-down allowance.)

Year 1: £25,000 × 18% = £4,500 allowance Year 2: (£25,000 − £4,500) × 18% = £3,690 allowance Year 3: (£25,000 − £4,500 − £3,690) × 18% = £3,025 allowance

If you're a limited company paying 20% corporation tax, that £4,500 allowance in year 1 saves you £900 in tax. If you're a sole trader paying 40% income tax, it saves you £1,800. Over time, the allowances compound, and you recover the full cost — spread over many years, not all at once.

Capital allowances are covered in detail on the HMRC website. The exact rate depends on the type of asset and whether you're a limited company or self-employed.

Leasing: The Tax Treatment

When you lease equipment, there's no capital allowance. Instead, the monthly (or annual) lease payment is a standard business expense.

Using the same van example: suppose a lease costs £350 per month (£4,200/year).

You deduct £4,200 from your business profit each year you're leasing. If you're paying 20% corporation tax, that saves you £840/year in tax. If you're a sole trader paying 40% income tax, it saves you £1,680/year. Lease payments are covered under business expenses guidance.

The advantage: relief is straightforward and doesn't depend on tracking asset values or depreciation. The disadvantage: you get no equity in the asset. After 3 years of leasing a van, you've paid £12,600 and own nothing.

Total Cost of Ownership: Buy vs Lease Over 5 Years

To compare properly, look at the full cost over the period you're actually using the equipment.

Buying scenario (limited company):

Purchase price: £25,000
Annual running cost (fuel, maintenance, insurance): £2,000/year
Tax rate: 20% corporation tax
Capital allowance: 18% reducing balance
Residual value after 5 years: £12,000 (typical for a van)

Year 1 costs: £2,000 − (£4,500 allowance × 20% = £900 tax relief) = £1,100 net cost, plus £25,000 upfront = £26,100 (first-year cash out) Years 2–5: £2,000/year − £168–280 annual tax relief ≈ £1,750/year net cost Total over 5 years: £26,100 + (4 × £1,750) = £33,100 Less residual value: £33,100 − £12,000 = £21,100 net cost

Leasing scenario (limited company):

Lease payment: £350/month = £4,200/year
Annual running cost: £500/year (tyres, minor repairs — lessor covers most)
Tax rate: 20% corporation tax
Total annual cost: £4,700
Tax relief on lease: £4,200 × 20% = £840/year
Net annual cost: £4,700 − £840 = £3,860

Total over 5 years: 5 × £3,860 = £19,300 net cost

In this scenario, leasing is cheaper by about £1,800 over 5 years. But the difference is narrower than the headline numbers suggest — the capital allowance on the purchase reduces the tax burden significantly.

Cash Flow vs Total Cost: The Hidden Trade-Off

The numbers above show total cost, but they don't tell the full story about cash flow.

When you buy equipment, you pay the capital cost upfront. That's £25,000 out of your business bank account on day one. The tax relief comes later, as you claim capital allowances (and you only get relief if your business is profitable enough to use it).

When you lease, you spread the cost over time. You're paying £350/month for 5 years. If your cash is tight, that's easier to manage. But leasing also means you pay more over the full term (in this example, £19,300 vs £21,100).

The decision between buy and lease often boils down to this: Do you have £25,000 to spare right now, and would you rather own the equipment at the end? Or would you prefer to preserve cash and hand it back?

If you're unsure whether to spend capital on equipment at all, our cash vs investing guide walks through how to think about opportunity cost — what else could that £25,000 earn if you didn't spend it?

Key Variables That Change the Calculation

A few factors can shift the buy vs lease decision dramatically:

Your tax rate. If you're a sole trader paying 40% income tax on profits, the capital allowance is worth more to you than it is to a limited company paying 20% corporation tax. That tilts toward buying. Our standard vs higher-rate taxpayer guide breaks down how tax brackets affect financial decisions like this one.

Equipment type. Some equipment qualifies for accelerated allowances or the super-deduction (50% first-year relief). Machinery and vehicles can qualify; some office equipment doesn't. Check with your accountant.

Lease terms. A cheap lease might tie you in for 5 years. A 3-year lease might be pricier per month but gives flexibility to upgrade.

Residual value. A van that holds its value well means you recover more at the end. IT hardware that's obsolete in 3 years means you recover almost nothing. We've covered the economics of new vs second-hand equipment — the same logic applies. Residual value is part of the total cost calculation.

Obsolescence risk. Do you need the equipment to be state-of-the-art? Leasing often includes upgrades; buying doesn't.

Which Option Is Right for Your Business?

Buy if:

You need the equipment for 5+ years
The asset holds its value well (vehicles, machinery)
You're a high-rate taxpayer (the capital allowance is worth more to you)
You want to own the asset at the end
The equipment is unlikely to become obsolete quickly

Lease if:

You're uncertain how long you'll need the equipment
You want a predictable monthly cost (easier budgeting and cash flow forecasting)
The equipment is likely to become obsolete (IT, vehicles needing replacement every 3 years)
You prefer to avoid upfront capital outlay
You want the lessor to handle maintenance and repairs

Frequently Asked Questions

Q: Can I claim capital allowances on a lease? A: No. When you lease, the lease payment is your deduction — there are no capital allowances on leased equipment. You get tax relief through the expense deduction, year by year, not as a capital allowance.

Q: What's the super-deduction, and does it apply to my equipment? A: The super-deduction was a temporary relief (2021–2023) offering 50% capital allowance in year one for eligible equipment. It has largely expired, but some provisions remain. Check the HMRC guidance on capital allowances for what your specific asset qualifies for.

Q: If I lease equipment for my business, is the lease payment fully deductible? A: Yes — the full lease payment is a business expense and reduces your taxable profit. However, if you use the equipment partly for personal use, you can only deduct the business-use portion.

Q: What happens to the capital allowance if I sell the equipment before it's fully written down? A: When you sell an asset, any difference between the sale price and the written-down value creates a balancing allowance (if you sell below) or balancing charge (if you sell above). If you sell for less than the written-down value, you can claim additional relief. If you sell for more, you may owe back some relief. Your accountant will handle this.

Q: Is leasing always more expensive than buying? A: Not necessarily. In the example above, the 5-year lease was slightly cheaper (£19,300 vs £21,100) than buying and selling. The actual comparison depends on the lease rate, residual value, your tax rate, and how long you use the equipment. Always run your own numbers.

Q: Can I use money saved from tax relief to pay down debt? A: Yes. The tax relief reduces your tax bill. What you do with that cash saving is up to you — reinvest it, pay down debt, or expand the business. The point is understanding how the tax impact affects how much you actually keep.

Q: Should I buy or lease if I'm unsure how long I'll need the equipment? A: Leasing is usually safer if uncertainty is high. You avoid the risk of owning equipment you no longer need. The trade-off is that you pay a bit more over the full term for that flexibility.

The Bottom Line

Buying business equipment gives you capital allowances and eventual ownership. Leasing gives you a predictable cost and flexibility. The real choice isn't about which is "better" — it's about which fits your business's cash flow, tax position, and growth plans.

Model both scenarios using your actual numbers: equipment cost, lease rate, tax rate, and duration of use. That's when the decision becomes clear.
