Simplified Expenses vs. Actual Costs: Which Vehicle Tax Deduction Method is Best for Delivery Drivers?

Simplified Expenses vs. Actual Costs for Your Vehicle

As a delivery driver or courier, your vehicle is your biggest business asset – and your vehicle costs are likely your largest tax deduction. But which method should you use: Simplified Expenses (Mileage) or Actual Costs?

Here's a detailed comparison to help you make the right choice for your delivery driver expenses.

Option 1: Simplified Expenses (Mileage Allowance)

HMRC's flat-rate mileage allowance lets you claim a set amount for every business mile driven:

• Cars & Vans: 45p per mile for the first 10,000 miles, then 25p per mile.
• Motorcycles: 24p per mile.
• Bicycles: 20p per mile.

Advantages:

• Simple – just track your miles, no receipts needed.
• Covers fuel, insurance, servicing, and depreciation in one rate.
• Great for newer or reliable vehicles with low running costs.

Disadvantages:

• Once you start using this method for a vehicle, you must continue with it.
• You cannot claim any other vehicle expenses (fuel, repairs, etc.).
• May not be beneficial if you have high maintenance or insurance costs.

Option 2: Actual Costs Method

With this approach, you claim the business proportion of your actual vehicle expenses:

• Fuel
• Insurance (including Hire & Reward)
• Road tax
• MOT and servicing
• Repairs and maintenance
• Lease payments or depreciation (capital allowances)

You calculate your business percentage by dividing business miles by total miles driven.

Advantages:

• Can result in higher deductions if you have significant vehicle expenses.
• Ideal for older vehicles needing frequent repairs.
• Beneficial if you have expensive insurance (e.g., Hire & Reward cover).

Disadvantages:

• More admin – you must keep all receipts and records.
• Requires calculating business vs. personal use percentage.
• Once you choose actual costs for a vehicle, you cannot switch to mileage.

Which Method Saves More Tax?

Let's look at an example. Assume you drive 15,000 business miles in a year:

Simplified Expenses:

• First 10,000 miles × 45p = £4,500
• Next 5,000 miles × 25p = £1,250
• Total deduction: £5,750

Actual Costs (example):

• Fuel: £3,000
• Insurance: £1,500
• Servicing & repairs: £800
• Road tax: £180
• Total costs: £5,480
• Business use: 80% → £4,384 deduction

In this example, Simplified Expenses wins (£5,750 vs £4,384). But if your repairs were £2,500 instead, actual costs might come out ahead.

Key Considerations for Gig Workers

• New or efficient car: Mileage is usually better.
• Older car with high repairs: Actual costs may save more.
• High-mileage driver: Mileage allowance becomes less attractive after 10,000 miles (drops to 25p).
• Electric vehicle: Actual costs can include home charging – potentially more beneficial.
