Running your own gardening or landscaping business? Whether you're mowing lawns for domestic clients, maintaining commercial grounds, or building patios and garden rooms — the tax rules apply from day one. This guide covers everything self-employed gardeners need to know about tax, expenses, and keeping HMRC happy.
Contents
When to Register with HMRC
You must register as self-employed if you earn more than £1,000 from gardening in a tax year. Register within 3 months of starting or face a £100 penalty.
Many gardeners start casually — mowing a neighbour's lawn, tidying a friend's garden. That's fine under the £1,000 trading allowance. But once you're doing regular work for paying customers, register properly.
See our registration guide for the step-by-step process.
Allowable Expenses for Gardeners
Every legitimate expense reduces your taxable profit — and gardening has plenty of them.
Materials and consumables
- Seeds, bulbs, plants, turf (if not charged to client separately)
- Compost, soil, mulch, bark
- Fertiliser, weed killer, pest control products
- Paving slabs, gravel, sand, cement (for landscaping)
- Timber, fencing panels, posts
- Plastic sheeting, landscape fabric
- Ties, stakes, netting
Business running costs
- Public liability insurance (essential — typically £60-£200/year)
- Professional indemnity insurance
- Employer's liability insurance (if you have staff)
- Phone and internet (business proportion)
- Accounting software or accountant fees
- Advertising: leaflets, Bark, Checkatrade, Facebook ads, Google Ads
- Website hosting and domain
- Business bank account fees
- Waste disposal / tip fees / skip hire
- Waste carrier licence (required if transporting green waste)
Clothing and PPE
- ✅ Steel-toe boots, safety goggles, ear defenders
- ✅ Waterproof jacket and trousers (work-specific)
- ✅ Branded uniform (polo shirts/fleece with business name)
- ✅ Gardening gloves (heavy-duty work gloves)
- ❌ Ordinary clothes — even if they get muddy and ruined
Equipment and Capital Allowances
Gardening equipment can be expensive. The good news: most of it qualifies for capital allowances, meaning you can deduct the full cost from your taxable profit in the year of purchase.
Claim in full (revenue expenses)
- Hand tools: secateurs, shears, rakes, forks, spades
- Replacement parts: mower blades, strimmer line
- Petrol and oil for equipment
- Small items under ~£500
Capital allowances (AIA — 100% first-year deduction)
- Lawn mowers (ride-on or push)
- Strimmers and brush cutters
- Hedge trimmers
- Leaf blowers
- Chainsaws
- Pressure washers
- Rotavators / tillers
- Mini diggers or tracked barrows
- Trailers
💡 Equipment tip: If you buy a £3,000 ride-on mower, you can deduct the full £3,000 from your taxable profit that year under AIA. At 20% tax rate, that saves you £600 in tax. Time big purchases before your tax year end (5 April).
Vehicle and Travel Costs
Most gardeners need a van or truck to carry equipment. You have two options:
Option 1: Simplified mileage
- 45p per mile (first 10,000 business miles)
- 25p per mile after that
- Keep a log of every business journey
Option 2: Actual costs
- Fuel, insurance, MOT, road tax, servicing, repairs
- Van lease or HP interest payments
- Claim the business-use proportion (e.g., 85% business = claim 85%)
For gardeners with high-mileage vans and significant fuel costs, actual costs usually work out better. See our Mileage Allowance Guide to compare both methods.
Trailer costs
If you tow a trailer with equipment or green waste:
- Trailer purchase: capital allowance (AIA)
- Trailer insurance, maintenance, tyres: revenue expenses
- Towing equipment: revenue expense
Managing Seasonal Income
Gardening income is seasonal — busy March to October, quieter November to February. This creates specific tax challenges:
The problem
- You earn most of your money in summer
- Your tax bill arrives in January — when income is lowest
- Payments on account (advance tax) add to the shock
The solution
- Set aside 25-30% of every payment into a separate savings account — immediately, not later
- Annual maintenance contracts: Offer customers monthly retainers for regular visits. This smooths your income across the year
- Winter services: Add pressure washing, gutter clearing, fence painting, leaf clearing to your services
- Equipment maintenance: Use winter downtime for tool servicing and repairs

Cash Payments and Record-Keeping
Gardening is one of HMRC's target sectors for cash economy investigations. Many domestic customers prefer to pay cash — that's fine, but you must declare it all.
Essential records to keep:
- A record of every job — date, customer, what you did, how much they paid
- Issue receipts for every cash payment
- Bank cash promptly — don't just spend it
- Keep receipts for all materials and fuel
How HMRC catches undeclared income:
- Material purchases that don't match declared turnover
- Lifestyle checks (nice van, holidays, but low declared income)
- Customer tip-offs (especially after disputes)
- Social media activity
- Checkatrade/Bark reviews showing more work than declared
Penalties range from 15% to 100% of unpaid tax. Keep clean records using our Invoicing Guide.
CIS for Landscapers
If you do landscaping work on building sites or for construction contractors (patios, driveways, groundwork), you may fall under the Construction Industry Scheme (CIS).
Under CIS:
- Contractors deduct 20% from your payments (30% if unregistered)
- Deductions count towards your tax bill — not extra tax
- You may get CIS refunds if you've overpaid
Pure garden maintenance (mowing, weeding, planting) typically doesn't fall under CIS. But hard landscaping (patios, walls, driveways, groundwork) often does when working for construction firms.
See our CIS & MTD Guide for details.
Tax-Saving Strategies for Gardeners
1. Claim everything
Most gardeners under-claim because they don't keep receipts for small purchases. Fuel, materials from the garden centre, dump fees, replacement tools — it all adds up. Aim to capture every expense.
2. Time equipment purchases
Had a good year? Buy that new mower or strimmer before 5 April. AIA lets you deduct the full cost immediately, reducing that year's tax.
3. Consider voluntary VAT registration
If most of your costs are VAT-able (fuel, materials, equipment) and your turnover is growing, voluntary VAT registration can let you reclaim VAT on purchases. But you'll need to charge VAT to customers — fine for commercial clients, less attractive for domestic ones.
4. Pension contributions
Put money into a SIPP to reduce your tax bill. Higher-rate taxpayers get 40% relief — the government adds £67 for every £100 you contribute (net cost £60). See our Pension Guide.
5. Employ family members
If your spouse or older children help with admin, bookkeeping, or physical work, you can pay them a reasonable wage. This uses their personal allowance and potentially saves tax overall. But the work must be genuine and the pay must be reasonable for the role.
Making Tax Digital (MTD)
From April 2026, self-employed gardeners earning over £50,000 must use MTD-compatible software for digital records and quarterly HMRC submissions. The threshold drops to £30,000 from April 2027.
Most gardeners keep simple records — income from clients, expenses for materials and fuel. An MTD-compatible app makes this easy. Many are free or low-cost.
