As a self-employed driving instructor you can deduct allowable business expenses from your turnover, so you only pay tax on your actual profit. The main claims are your tuition car and its running costs, fuel, insurance, franchise fees, ADI registration and training, and your phone and business software. Anything used wholly and exclusively for the business is generally allowable; for the car you choose either flat-rate mileage or actual costs plus capital allowances.
This guide lists what you can claim, explains the two ways to handle car costs, and covers the record-keeping that keeps it all defensible.
What counts as an allowable expense?
An allowable expense is a cost incurred wholly and exclusively for your instructing business. Claiming it reduces your taxable profit, which directly lowers your Income Tax and National Insurance bill, so every legitimate expense you record is money you keep.
The “wholly and exclusively” test is the key one. A cost that is purely business (your ADI registration, tuition insurance, a booking subscription) is fully allowable. A cost that is part business and part personal (your mobile phone, a car you also use privately) can only be claimed for the business proportion. You cannot claim personal spending, fines and penalties, or the cost of your own everyday clothing. Claiming everything you are entitled to, and nothing you are not, is the goal.
What expenses can a driving instructor claim?
Here are the expenses instructors most commonly claim. The list is not exhaustive, but it covers the great majority of a typical ADI’s costs.
| Expense | Allowable? | Notes |
|---|---|---|
| Tuition car (dual controls) | Yes | Via capital allowances or mileage method |
| Fuel | Yes | Business proportion; or covered by mileage rate |
| Car insurance, tax, servicing, repairs, tyres | Yes | Actual-cost method only |
| Franchise fees | Yes | Fully allowable if on a franchise |
| ADI registration and standards check | Yes | Ongoing professional costs |
| Training and CPD | Yes | To maintain or update skills |
| Mobile phone | Partly | Business proportion of the bill |
| Business software (booking, diary, finance) | Yes | Includes tools like Passly |
| Advertising and marketing | Yes | Website, listings, ads, printing |
| Accountancy and bank charges | Yes | Business account and accountant fees |
| Stationery, dash cam, teaching aids | Yes | Used for the business |
| Use of home as office | Yes | A reasonable proportion, or flat rate |
Two costs deserve their own explanation, because they are the biggest and the most-asked-about: the car and your software and phone.
How do you claim car costs: mileage or actual?
The car is almost always an instructor’s largest expense, and HMRC gives you two ways to claim it. You must pick one method per vehicle and stick with it for that car; you cannot mix them or swap year to year for the same car.
The simplified mileage method
You claim a flat rate for every business mile driven (HMRC’s approved mileage rate), and that single figure is meant to cover fuel, servicing, insurance, depreciation and repairs. You keep a mileage log and claim nothing separately for those running costs.
This method is simple and light on record-keeping, and it can suit instructors with a lower-value or personally-owned car. The trade-off is that it may under-claim for an expensive, heavily-used tuition car, because the flat rate is designed for average motoring, not high-mileage professional use.
The actual-cost method with capital allowances
Here you claim the real running costs (fuel, insurance, tax, servicing, repairs, tyres) for the business proportion of use, plus capital allowances on the car itself. A capital allowance spreads the cost of the vehicle across several years as a deduction against profit; for cars the rate depends on CO2 emissions.
This method usually gives a bigger deduction for a costly, high-mileage tuition car, which describes most instructors, but it demands full records of every cost and correct handling of capital allowances and private-use adjustments. Because capital allowances get fiddly (especially with part-personal use, leasing, or an electric car), this is the area where an accountant most often earns their fee. If in doubt, get advice before you choose, because the decision is hard to reverse for that vehicle.
Can you claim your phone and software?
Yes. You can claim the business proportion of your mobile phone contract and the full cost of software you use to run the business. For a phone used for both pupils and personal life, estimate a fair business percentage and claim that share consistently.
Business software is fully allowable when it is used wholly for the business. That includes booking, diary, pupil-management and finance tools. Passly is exactly this kind of cost: your Passly subscription is an allowable business expense, and its finances and expense tracking also helps you record income and payments through the year so your figures are ready at tax time. The subscription pays for itself in admin time and then reduces your tax bill on top.
What about franchise fees, training and registration?
If you work on a franchise, your weekly or monthly franchise fee is a fully allowable business expense, which is worth remembering when you compare the franchise and independent routes. So are your professional costs as an ADI: your registration fee, any standards-check-related costs, and ongoing training or continuing professional development to maintain and update your skills.
These are ordinary, recurring costs of being an instructor, and they add up, so make sure they are all captured. Our franchise versus independent guide looks at how franchise fees affect your overall economics, and the franchise cost calculator helps you weigh the fee against what it includes.
How should you keep records of expenses?
You must keep evidence of every expense you claim (receipts, invoices, bank statements and a mileage log) for at least five years after the 31 January filing deadline. You do not send them to HMRC, but you must be able to produce them if asked.
The easiest approach is to record costs as they happen rather than reconstructing the year in January. A dedicated business bank account keeps personal and business spending cleanly separated, a photo of each receipt saves you hunting for faded paper, and a simple running total tells you where you stand. Tracking income and payments in Passly alongside your expense records gives you and your accountant a clean, exportable picture at year end.
How do expenses fit into your tax bill?
Every allowable expense reduces your profit, and it is profit (not turnover) that you pay Income Tax and National Insurance on. So a well-kept expenses list is one of the most effective legitimate ways to lower your tax bill as an instructor.
The mechanics are covered in our tax guide for instructors, and you can see how expenses feed into take-home pay in the salary guide and the earnings calculator. This article is general guidance rather than tailored advice; because expenses, capital allowances and private-use adjustments can get genuinely complicated, it is worth speaking to an accountant to make sure you claim everything correctly and nothing you should not.
