Self-Employed Gardener Tax Guide UK 2026/27
From mowing a few local lawns to running a full landscaping round with a van and equipment, self-employed gardeners have their own set of allowable expenses and registration thresholds. Here is how gardening income is taxed in 2026/27.
The trading allowance threshold
Whether you cut a handful of neighbours' lawns for pocket money or run a full landscaping round, the same £1,000 gross income threshold determines whether you need to register with HMRC at all — below it, the income is entirely tax-free.

Steve runs a regular gardening round earning £26,000 a year, driving a van he uses solely for the business (11,200 business miles that year), plus £1,900 of other allowable expenses (tools, insurance, disposal fees).
| Item | Amount |
|---|---|
| Gross income | £26,000 |
| Mileage claim: 10,000 miles at 45p | £4,500 |
| Mileage claim: remaining 1,200 miles at 25p | £300 |
| Other expenses | £1,900 |
| Total allowable expenses | £6,700 |
| Taxable profit | £19,300 |
| Class 4 NI (6% on profit above £12,570) | £402 |
| Income Tax at 20% on profit above the Personal Allowance | £1,346 |

Steve also does a one-off garden redesign job, buying £600 of plants and turf, and charges the client £900 for the materials (a £300 markup) on top of his labour fee.
| Item | Amount |
|---|---|
| Materials cost | £600 (allowable expense) |
| Amount charged to client for materials | £900 (taxable income) |
| Net effect on taxable profit | +£300 (the markup) |
Choosing mileage over actual costs
For most sole trader gardeners, simplified mileage rates remove the need to apportion insurance, servicing, fuel receipts and depreciation between business and any personal use of the vehicle — a meaningful administrative saving, provided the vehicle is not so expensive or high-mileage that actual costs would clearly produce a larger, defensible claim instead.
Frequently asked questions
At what point do I need to tell HMRC about my gardening income?
You need to register for Self Assessment once your gross gardening income for a tax year exceeds £1,000 (the trading allowance). Below that threshold, occasional or hobby-level gardening income is entirely tax-free and does not need to be reported, though many gardeners with a regular round quickly exceed £1,000 and need to register.
What counts as an allowable business expense for a self-employed gardener?
Common allowable expenses include a mower, strimmer, hedge trimmer and other tools, fuel and maintenance for equipment, a van or vehicle used for the round (either mileage at HMRC's approved rates or actual running costs), public liability insurance, waste disposal or green-waste tipping fees, marketing (flyers, a website, local advertising), and a proportion of home costs if you do admin or store equipment at home.
Should I claim mileage or actual vehicle costs for my van?
Most self-employed gardeners with a dedicated work van find HMRC's simplified mileage rates (45p per mile for the first 10,000 business miles in the tax year, 25p per mile after) simpler to track than actual costs, though if your vehicle has high running or finance costs relative to its mileage, calculating actual costs (fuel, insurance, servicing, a business-use proportion of finance or depreciation) can sometimes produce a larger claim — you must pick one method per vehicle and use it consistently.
Can I claim for a chainsaw, ride-on mower or other expensive equipment?
Yes — larger equipment purchases are generally claimed via the Annual Investment Allowance, deducting the full cost against your trading profit in the year of purchase (subject to the AIA limit, which is far higher than most individual gardening equipment purchases), rather than spreading the cost over several years.
Do I charge VAT on my gardening work?
Only once your total self-employed turnover exceeds £90,000 in a rolling 12-month period, at which point VAT registration becomes compulsory. Most individual and small-team gardeners remain below this threshold, though a growing landscaping business with several staff and larger contracts should monitor cumulative turnover carefully.
How is my gardening profit taxed?
Profit (gross income minus allowable expenses, or minus the £1,000 trading allowance if that produces a lower figure) is taxed through the normal Income Tax bands, plus Class 4 National Insurance at 6% on profits between £12,570 and £50,270 and 2% above that, reported annually via Self Assessment.
Can I claim for plants and materials I buy and then charge the client for?
Yes — where you buy plants, compost, turf or other materials specifically for a client's job and recharge the cost (with or without a markup), the cost of those materials is an allowable expense, and the amount you charge the client for them forms part of your taxable income, so the two roughly net off, with any markup you add being genuine taxable profit.
Do I need public liability insurance and is it tax deductible?
It is not a strict legal requirement, but many clients (particularly commercial or larger residential contracts) expect proof of public liability insurance before hiring a gardener, given the obvious risks of using power tools and ladders on someone else's property, and the premium is a straightforward allowable business expense.
