Delivery Driver Self-Assessment Guide by Marsal Accountants in Paisley

Working as a self-employed delivery driver for platforms like Uber Eats,
Just Eat, and Deliveroo offers flexibility—but it also comes with tax responsibilities.
At Marsal Accountants, based in Paisley and serving
Glasgow and Central Scotland, we help delivery drivers prepare and submit their
Self Assessment tax returns accurately and on time.

This step-by-step guide explains what Self Assessment is, the records you need, and how professional support can save you time, money, and stress.

What Is Self Assessment for Delivery Drivers?

Self Assessment is HMRC’s system for reporting income and expenses if you’re self-employed.
Delivery drivers are responsible for completing their annual tax return to ensure they pay the correct amount of tax.

Why Filing Matters

Failing to file on time can lead to:

• Late filing penalties
• Interest on unpaid tax
• Complications with HMRC that could affect your work

Filing correctly ensures you claim all allowable expenses and only pay what you owe.

Records Delivery Drivers Should Keep

Income Records

• Delivery fees (base pay)
• Boosts, incentives, and bonuses
• Cash and card tips

Allowable Expenses

• Fuel (for car or motorbike)
• Vehicle or bike insurance
• Repairs, servicing, tyres, chain, brakes
• Protective gear and delivery bags
• Business-use portion of phone and data plan
• Parking, tolls, congestion charges
• Cycle maintenance and parts (if applicable)

Other Supporting Documents

• Receipts and invoices
• Mileage or journey logs
• Bank statements (including platform payouts)

Mileage vs Actual Costs

You can usually choose between claiming mileage (fixed rate per business mile)
or actual costs (fuel, repairs, insurance, etc.). Pick the method that gives the best legitimate deduction and keep consistent records.

Registering for Self Assessment

• Register with HMRC – Provide personal and business details.
• Get your Unique Taxpayer Reference (UTR) – A 10-digit number for your tax account.
• Set up a Government Gateway account – Required for online filing.

Filing Your Self Assessment Return

Most delivery drivers complete the SA100 (main tax return) and SA103 (self-employed pages).

• Enter all income from deliveries, incentives, and tips
• Claim all allowable business expenses
• HMRC calculates your tax automatically

Filing online is faster and gives you extra time compared to paper submissions.

Key Deadlines to Remember

• Paper return: 31 October
• Online return: 31 January
• Tax payment: 31 January

Common Mistakes Delivery Drivers Make

• Forgetting to include cash tips
• Not claiming mileage or under-claiming expenses
