Tax Return in Glasgow: Step-by-Step Filing Guide for Drivers

To file your tax return in Glasgow as a ride-hailing, private hire or taxi driver, you sign in to HMRC online, enter your gross fares and allowable expenses on the self-employment pages, and submit by 31 January 2027. The tax return is the same as anywhere in the UK, but your profit is taxed at Scottish Income Tax rates.

This is a practical, screen-by-screen walk-through for the 2025/26 tax return, which covers 6 April 2025 to 5 April 2026. It is written for drivers licensed in Glasgow who want to file it themselves, or who want to understand what their accountant is doing. We explain each step in order, show a full worked bill, and flag the Glasgow details that trip people up.

We do not repeat the background here. If you want the bigger picture on registering and deadlines, read our Glasgow Self Assessment 2026 update. This piece is the how-to: what to type, where, and what to check before you press submit.

Key takeaways

• Glasgow drivers file their tax return with HMRC, not Revenue Scotland. The online deadline for 2025/26 is 31 January 2027.
• Enter gross fares and tips as turnover, then claim platform fees, mileage and other costs as expenses.
• For 2025/26, the simplified mileage rate is 45p a mile for the first 10,000 business miles, then 25p. The 55p rate only starts in 2026/27.
• Scottish Income Tax bands apply to your driving profit, but Class 4 National Insurance is the same UK-wide.
• Glasgow licence fees are normally allowable; Low Emission Zone fines are not.

What is a tax return?

A tax return is the yearly Self Assessment form you send to HMRC to report income that has not been taxed at source. For a self-employed Glasgow driver, it records fares, expenses and profit, and HMRC uses it to work out your Income Tax and National Insurance.

Who in Glasgow needs to file a 2025/26 tax return?

You need to file if you were self-employed as a driver in 2025/26 and your gross driving income was over £1,000. That covers ride-hailing drivers, private hire drivers working through Glasgow operators, and hackney cab drivers. It applies even if you also have a PAYE job, because both incomes go on one return.

If you started driving during 2025/26 and never registered, you should have told HMRC by 5 October 2026. If you missed that, register now through the Self Assessment registration service on GOV.UK. You cannot file online until your 10-digit Unique Taxpayer Reference (UTR) arrives, and that can take a couple of weeks. Our guide to your first tax return as a new ride-hailing driver covers registration in detail.

What do you need before you start your tax return?

Before you sign in to start your tax return, gather your UTR, National Insurance number, Government Gateway login, annual statements from every app, cash and account fare records, a mileage log, and receipts for each expense. Add any P60, pension or savings interest figures. Having everything in one folder turns a stressful evening into about an hour's work.

• Your 10-digit UTR and National Insurance number.
• Your Government Gateway user ID and password for your HMRC online account.
• The annual tax summary from each driver app you use, showing gross fares, tips and service fees for 6 April 2025 to 5 April 2026.
• Records of cash fares and account work from Glasgow private hire or taxi operators.
• A business mileage log for the year. Our guide to HMRC mileage logs and bookkeeping shows what it should contain.
• Receipts for licence fees, medicals, phone, accountancy, parking and any other business costs.
• A P60 if you also had a job, plus details of pension contributions, Gift Aid and savings interest.

How do you file your tax return in Glasgow, step by step?

Sign in to HMRC online, confirm your personal details and Glasgow address, choose the self-employment section, enter turnover and expenses, add any other income, then review the tax calculation before submitting. Finally, note the amount due and pay HMRC using your UTR followed by K. The ten steps below follow the order you will see on screen.

1. Sign in to your HMRC online account through the Self Assessment sign-in page on GOV.UK and choose the 2025/26 tax return.
2. Check your personal details, especially your Glasgow home address, because HMRC uses where you live to decide whether you are a Scottish taxpayer.
3. Answer the tailoring questions. Say yes to self-employment, and yes to employment only if you also had a PAYE job.
4. Enter your business details: a short description such as private hire driver, your start date if you began in the year, and your accounting period, usually 6 April 2025 to 5 April 2026.
5. Enter your turnover: gross fares and tips from every app and operator, before platform fees are taken off.
6. Enter your expenses, either as itemised categories or as one total if turnover was under the VAT threshold of £90,000. Include platform service fees, simplified mileage at 45p and 25p, licence fees, phone and accountancy.
7. Add any other income, such as PAYE wages from your P60, bank interest or rental income, and any pension contributions or Gift Aid.
8. Save, then view the tax calculation. Check that it shows Scottish rates such as the 19% starter rate and the 21% intermediate rate, and that Class 4 National Insurance is at 6%.
9. Submit the tax return and save the submission receipt and reference number HMRC shows on screen.
10. Pay the tax return balance and any first payment on account by 31 January 2027, quoting your UTR followed by the letter K.

Step 2 in detail: the Scottish taxpayer check

You do not apply to become a Scottish taxpayer. If your main home is in Scotland, Scottish Income Tax applies automatically. The risk is that HMRC holds an old address in England, so your tax return is calculated at the wrong rates. Update your address in your HMRC account before you file, not after. Drivers with homes on both sides of the border should read our Scottish taxpayer FAQ for drivers.

Step 6 in detail: itemised or one total

If your turnover was below £90,000, the short self-employment pages let you enter one figure for total expenses. That is quicker, but itemising is safer if you ever face questions, because you can match each box to a pile of receipts. Whichever you choose, keep the working papers that show how you reached the figure.

How do you work out turnover from app work and cab fares?

Turnover is your gross takings for 6 April 2025 to 5 April 2026, before any deductions. For app drivers that means total fares plus tips, not the lower amount paid into your bank. Add cash fares, account work and any bonuses. Platform service fees are then claimed separately as an expense, so nothing is counted twice.

The most common error we see is entering the weekly payouts as turnover. Payouts are net of service fees, so entering them understates turnover and hides costs you could claim. HMRC receives information from digital platforms, so your figures should reconcile to the annual summaries. If you drive for more than one app, add each summary separately, then add your own records for cash and street hails.

Hackney cab drivers in Glasgow often take more cash. Keep a daily takings sheet or a log in an app, and bank cash regularly so the deposits match your records. A tidy cash record is the strongest evidence you can have if HMRC ever opens an enquiry.

Which expenses go on a Glasgow driver's tax return?

You can claim costs incurred wholly for the business: platform service fees, vehicle costs or simplified mileage, Glasgow City Council licence fees, licensing medicals, phone use, accountancy and parking. You cannot claim fines, commuting or private trips. For 2025/26, simplified mileage is 45p a mile for the first 10,000 business miles, then 25p.

According to HMRC's simplified expenses guidance for vehicles, cars are claimed at 45p a mile for the first 10,000 miles before 6 April 2026, and 55p from 6 April 2026. Both bands drop to 25p after 10,000 miles. So the 2025/26 return uses 45p, and the 55p rate first appears on your 2026/27 return. Once you use flat rates for a vehicle, you must keep using them for as long as that vehicle is in the business.

The flat rate replaces your actual running costs: fuel, insurance, servicing, repairs, road tax and depreciation. Do not claim private hire insurance or fuel on top of mileage. Parking and tolls are separate and can still be claimed. Our Glasgow mileage allowance guide compares the flat rate with actual costs, and the full list of claims is in our allowable expenses guide for ride-hailing drivers.

Glasgow City Council licence fees

Glasgow City Council licenses taxi drivers, private hire car drivers and their vehicles. The fees you pay to grant or renew a driver's licence or vehicle licence are a cost of being able to trade, so they are normally allowable in the year you pay them. The council's website blocked our automated checks this run, so we do not quote a fee here. Check the current amount on the council's licensing pages and claim the figure on your receipt.

Related costs, such as a licensing medical or the course and certificate the council requires, are usually claimable too, if they relate to your driving business. Scottish licence renewals also require an HMRC tax check, which is one more reason to keep your returns up to date. Search GOV.UK for the taxi and private hire licence tax check to see what a renewal needs.

Glasgow Low Emission Zone fines

Glasgow's Low Emission Zone (LEZ) covers the city centre and runs 24 hours a day. According to mygov.scot's LEZ fines page, the first Penalty Charge Notice is £60, cut to £30 if paid within 14 days, and it doubles for repeat breaches in the same zone within 90 days, up to £480 for cars. HMRC's travel expenses guidance says fines and penalty charges cannot be claimed. Leave any LEZ penalty out of your expenses.

How do Scottish tax bands change your tax return?

Your tax return looks identical, but HMRC applies Scottish Income Tax bands to your driving profit and other non-savings income. For 2025/26 there are six Scottish rates, from a 19% starter rate to a 48% top rate. Savings interest and dividends use UK rates, and National Insurance is UK-wide, so only part of the bill changes.

According to GOV.UK's Scottish Income Tax rates for 2025 to 2026, the bands below apply to the return you are filing now. We show 2026/27 alongside so you can budget for next year's bill. Both assume the standard £12,570 Personal Allowance.

For 2025/26, Class 4 National Insurance is 6% on profits between £12,570 and £50,270 and 2% above that, wherever you live in the UK. Class 2 is treated as paid once profits reach £6,845, so most full-time drivers pay nothing extra. Below that you can choose to pay voluntary Class 2 at £3.50 a week to protect your State Pension record.

Illustrative example: a Glasgow private hire driver's 2025/26 tax return

This is an illustrative example using an invented driver. Ewan lives in Dennistoun and drives a private hire car through an app and a local operator. 2025/26 is his first year of self-employment, he has no other income, and he uses simplified mileage. He drove 14,000 business miles in the year.

Ewan's Scottish Income Tax is £1,949.73. A driver with the same profit in England would pay £1,978 at the 20% basic rate, so at this level the Scottish bill is £28.27 lower. National Insurance is the same either side of the border. Had Ewan also paid a £60 LEZ penalty in the year, it would stay out of his expenses entirely.

Because his bill is over £1,000 and none of it was taxed at source, HMRC will also ask for payments on account towards 2026/27. Each is half of this year's bill, £1,271.57. So on 31 January 2027 Ewan pays £3,814.70, and on 31 July 2027 he pays another £1,271.57. Our tax calculator lets you run your own figures.

How do you check and submit the tax return?

Before submitting, open the tax calculation and compare it with your own estimate. Check that turnover matches your app summaries, that mileage uses 45p for 2025/26, and that Scottish bands are shown. Then submit the tax return, save the receipt and reference, and diary the payment dates. You can still amend the tax return later if you spot an error.

Read the calculation line by line. If you see a single 20% basic rate band running from £12,571 to £50,270, HMRC is treating you as a taxpayer outside Scotland, and your address needs checking. If Class 2 appears as a charge when your profit is well above £6,845, look again at the figures you entered.

According to GOV.UK, you must wait 72 hours after filing before updating your tax return, and you can amend it online within 12 months of the deadline. For 2025/26 that means up to 31 January 2028. If the correction increases the tax due, pay the difference quickly to keep interest down.

How do you pay HMRC, and when is the money due?

Pay the 2025/26 balance, plus any first payment on account, by 31 January 2027. The second payment on account is due by 31 July 2027. Pay online through your bank, by debit card or by Direct Debit, using your UTR followed by K as the reference, and allow extra days for slower methods.

HMRC's Self Assessment bank details page confirms the reference is your 10-digit UTR followed by the letter K. Using the wrong reference can delay the payment or put it against a different bill. Faster Payments and card payments usually arrive the same or next day, but setting up a Direct Debit for the first time takes 5 working days.

According to HMRC's guidance on payments on account, you do not make them if last year's bill was under £1,000, or if more than 80% of your tax was already collected outside Self Assessment, for example through PAYE. If your 2026/27 earnings are falling, you can ask HMRC to reduce them, but only on a realistic estimate.

What does this year's tax return mean for Making Tax Digital?

Your 2025/26 return matters beyond this year's bill. HMRC uses the qualifying income it shows to decide whether you must join Making Tax Digital (MTD) for Income Tax. If qualifying income is over £30,000, you must use MTD software and send quarterly updates from 6 April 2027. The threshold falls to £20,000 from April 2028.

Qualifying income is broadly your gross self-employment and property income before expenses, so a busy Glasgow driver can cross £30,000 even with a modest profit. Ewan's £36,000 turnover would bring him into MTD from April 2027. Our guide to Making Tax Digital for ride-hailing drivers explains the quarterly routine, and turnover above £90,000 also triggers VAT, covered in our Glasgow VAT registration FAQ.

Common tax return mistakes and the penalty each triggers

• Filing after 31 January 2027: HMRC's Self Assessment penalties page sets an automatic £100 penalty, then £10 a day after 3 months up to £900, then 5% of the tax due or £300 at 6 and 12 months, whichever is greater.
• Paying late: 5% of the unpaid tax at 30 days, 6 months and 12 months, plus interest on the amount owed.
• Entering bank payouts instead of gross fares: understated turnover can lead to an HMRC enquiry and inaccuracy penalties based on the extra tax due.
• Using 55p a mile on the 2025/26 return: that rate only starts on 6 April 2026, so it overclaims and has to be corrected, with interest on any tax underpaid.
• Claiming insurance or fuel on top of simplified mileage: this double-counts vehicle costs and is a common reason for an amended return.
• Including a Low Emission Zone penalty as an expense: fines are not allowable, so the claim must be reversed.
• Leaving an old English address on file: your profit is taxed at the wrong rates and you will need to correct it with HMRC.
• Registering late: if you register late and do not pay in full by 31 January, you may get a failure to notify penalty.
