Self Assessment Software Checklist for Drivers Who Are Also Landlords

The right self assessment software for a driver who also lets property must handle two separate income sources: your driving business and your UK property business. It must keep separate digital records for each, send a separate quarterly update for each, and pull both into one tax return by 31 January.

This checklist is for ride-hailing, private hire and taxi drivers who also receive rent. It covers how your driving and rental income combine for Making Tax Digital (MTD), what to check before you pay for a product, and how to set it up so the property rules work properly. If you only drive, start with our general guide to Self Assessment software and MTD instead.

Key takeaways

• MTD for Income Tax adds your gross self-employment turnover and your gross property income together. A driver with £35,000 of fares and £20,000 of rent has £55,000 of qualifying income.
• Your self assessment software must treat driving and letting as two separate businesses, with two sets of records and two quarterly updates every quarter.
• It must flag residential finance costs, such as mortgage interest, separately, because they get a 20% tax reduction rather than a straight deduction.
• It should let you choose between the £1,000 property allowance and actual expenses, and record only your share of any jointly owned property.
• Use HMRC's own software finder to shortlist products. HMRC recognises software but does not recommend any provider.

What is self assessment software for driver-landlords?

Self assessment software for driver-landlords is an HMRC-recognised product that keeps digital records for both a self-employed driving business and a UK property business. It sends quarterly updates for each source and files one combined tax return, including the property-only rules on finance costs and allowances.

Why does rental income change which software you need?

Rental income changes your software needs because HMRC treats letting as a separate business with its own records, categories and quarterly updates. Self assessment software built only for sole traders may not support a UK property business at all. If it cannot, you would need a second product, and the two must work together.

Most drivers start with simple self assessment software or an app that tracks fares, fuel and mileage. That is fine for a driving-only return. Once rent arrives, the software has to report a second business, apply a different set of expense categories and handle rules that only exist for landlords.

HMRC's guidance on choosing software for MTD for Income Tax says compatible software must support all your income sources, let you make your submissions and work with your accounting period. It also says you can use more than one product, but only one per separate submission. For a driver-landlord, that means checking property support before anything else.

Does rental income count towards the MTD £50,000 threshold?

Yes. HMRC defines qualifying income as your total income from self-employment and property, before expenses. Your gross fares and your gross rent are added together. Employment pay, dividends and pensions do not count. So rent can push a driver over the threshold even when driving alone would not.

According to HMRC's guidance on working out your qualifying income, the figure is your turnover, not your profit. For a driver, that is gross fares before platform service fees, fuel and other costs, as shown in your accounts. For a landlord, it is the rent received before letting fees, repairs and mortgage interest.

The thresholds are phased in. Qualifying income above £50,000 brought people into MTD from 6 April 2026, above £30,000 does so from 6 April 2027, and above £20,000 from 6 April 2028. HMRC looks at your Self Assessment return for the tax year two years earlier, so the 2024/25 return decided who started in April 2026.

How joint ownership affects the threshold

If you own a rental property with someone else, only your share of the rent counts. HMRC's own example shows two siblings sharing £50,000 of rent equally, with each having qualifying income of £25,000. If you co-own a flat with your partner, your software should hold your share only, not the whole rent.

Self assessment software checklist: 10 things to confirm before you buy

Use this list when you compare self assessment software on HMRC's finder or ask a provider questions. Each point relates to something a driver-landlord return actually needs. If a product fails one of the first four, it is probably not right for you, however good the mileage tracker looks.

1. Both income sources supported. It must handle self-employment and UK property in the same account, or work alongside a second product that covers the gap.
2. Separate quarterly updates. It should create one update for your driving business and one for your property business, each quarter.
3. Residential finance costs flagged. It must let you record mortgage interest and similar costs in their own category, so the 20% tax reduction can be worked out at year end.
4. Property allowance option. It should let you choose the £1,000 property allowance or actual expenses, and stop you claiming both.
5. Joint property support. It should let you record your share only, and choose whether to include joint expenses in quarterly updates or add them at year end.
6. Driving categories. It should support simplified mileage or actual vehicle costs, platform fees, licensing and phone costs for the driving side.
7. Other income on the tax return. It must let you add employment, savings or other income before you submit your tax return by 31 January.
8. Bank feeds or imports. It should import transactions from your bank, or accept spreadsheet uploads, so you are not retyping every fare.
9. Agent access. If an accountant helps you, check they can view your records and submit on your behalf.
10. Export and history. You should be able to download your records, because you must keep them even if you change provider.

Cost matters, but it is the last check, not the first. A cheap product that cannot report property income will cost you more in time and corrections than it saves.

What records does the software need for each income source?

Each digital record needs a date, an amount and a category. Driving and letting use different categories, so your self assessment software must keep them apart. You do not need a separate business for each UK rental property, because all your UK lets form one property business. Foreign property follows different rules.

HMRC's guidance on creating digital records lists examples. Self-employment income includes sales, takings and fees, and expenses include travel costs, office costs and financial costs. Property income includes rent and lease premiums, and property expenses include repairs, maintenance and services. The categories match those on the Self Assessment return.

HMRC allows simpler categorisation if your turnover from a source is under £90,000. A sole trader can then record only whether each item is income or an expense. Landlords with UK residential property must still record whether an expense is a restricted finance cost, even below that limit. Check your self assessment software applies this correctly.

For the driving side, a clean mileage log is still the foundation. Our guide to mileage logs and bookkeeping records explains what to keep, and our mileage calculator works out the 2026/27 simplified rate of 55p a mile for the first 10,000 miles and 25p after that.

How should software handle the property allowance and actual expenses?

Good self assessment software lets you compare the £1,000 property allowance with your actual expenses and pick one. You cannot claim both. GOV.UK also says you cannot use the property allowance if you claim relief for residential finance costs, such as mortgage interest. Each joint owner gets their own £1,000 allowance against their share.

According to HMRC's guidance on the property and trading allowances, if your gross property income is £1,000 or less, you may not need to declare it. Above that, the allowance is deducted instead of expenses. It suits a driver who lets a driveway or a small room with almost no costs.

For most buy-to-let landlords, actual expenses are higher than £1,000, so the allowance rarely helps. Self assessment software should make the comparison visible rather than choosing silently. Keep a record of which method you used each year, so your figures stay consistent.

How does the finance cost restriction work in your software?

For residential lets, mortgage interest and other finance costs are not deducted from rental income. Instead, you get a tax reduction worth 20% of the lowest of your finance costs, your property profits or your adjusted total income. Your self assessment software must record finance costs separately so this calculation is right.

According to HMRC's guidance on tax relief for residential landlords, this rule has been fully in place since 6 April 2020. Any unused amount can be carried forward to later years. The reduction cannot create a tax refund.

This is where generic sole trader apps often struggle. If mortgage interest is coded as an ordinary expense, your quarterly figures will show a lower property profit than HMRC's calculation will use. Test this during a free trial by entering a sample interest payment and checking where it lands.

How many quarterly updates will a driver-landlord send?

A driver who also lets UK property sends two quarterly updates each quarter: one for driving and one for letting. That is eight updates across the tax year, plus one tax return by 31 January. Each update is a year-to-date summary of category totals, not a tax bill and not a tax return.

HMRC's guidance on sending quarterly updates sets the standard periods from 6 April. The deadlines are 7 August, 7 November, 7 February and 7 May. If your accounting period runs from 1 April, you can use calendar quarters instead, with the same deadlines. For 2026/27, the update covering 6 April to 5 October 2026 is due by 7 November 2026.

Mistakes are corrected in your next update rather than by resubmitting. For jointly owned lets, you can choose to include only your share of income in quarterly updates and add the joint expenses before you submit your tax return. If you also own other properties alone, their income and expenses must go into the updates as normal.

Bridging software or full software: which suits a driver-landlord?

Bridging software suits a driver-landlord who already keeps tidy spreadsheets and only needs to send figures to HMRC. Full software suits someone who wants bank feeds, receipt capture and a running tax estimate. Both can be compatible, as long as the product covers property and self-employment for your submissions.

HMRC's software guidance says bridging software connects to records you already keep, such as spreadsheets, and makes submissions for you. Some bridging products send quarterly updates and also file the tax return. Others do not, which would leave you needing a second product at year end.

• Bridging suits you if: you have one rental property, a simple spreadsheet you trust, and you are happy to update it weekly.
• Full software suits you if: you drive for more than one platform, have several transactions a day, or want receipts stored with each entry.
• Either way: confirm the product covers UK property income and the final tax return, not just quarterly updates.

How to set up self assessment software: step by step

1. Work out your qualifying income from your latest return: gross fares plus your share of gross rent.
2. Use HMRC's finder to list recognised products that support both self-employment and UK property income.
3. Sign up for MTD for Income Tax through GOV.UK, or ask your agent to do it, before connecting the software.
4. Create two businesses in the software: your driving business and your UK property business.
5. Set your accounting period, usually 6 April to 5 April, and choose standard or calendar quarters.
6. Set up categories, including a separate finance cost category for mortgage interest.
7. Connect your bank account or upload your spreadsheet, and record mileage from day one of the tax year.
8. Diarise the four deadlines and review each update for both businesses before you submit it.

If this is your first property, read our landlord tax update for drivers before step 1. It explains registering rental income and how the Furnished Holiday Lettings changes affect you, which we do not repeat here.

Worked example: a driver-landlord choosing software

This is an illustrative example using an invented driver. Dele drives for two ride-hailing apps and owns a one-bedroom flat outright in his own name, with a buy-to-let mortgage. His 2024/25 return showed £35,000 of gross driving income and £20,000 of gross rent.

• Qualifying income: £35,000 + £20,000 = £55,000. That is over £50,000, so Dele had to use MTD from 6 April 2026.
• Driving side in 2026/27: 18,000 business miles. Simplified mileage is 10,000 × 55p = £5,500, plus 8,000 × 25p = £2,000, so £7,500.
• Property expenses: letting agent £1,800, repairs £1,200, landlord insurance £400. Total £3,400.
• Mortgage interest: £6,000, recorded in the finance cost category, not as an expense.
• Property profit: £20,000 − £3,400 = £16,600. The 20% reduction is worked out on the lowest of £6,000, £16,600 and his adjusted total income. Assuming £6,000 is lowest, the reduction is £1,200.
• Property allowance check: £20,000 − £1,000 = £19,000 taxable, and no finance cost reduction. Actual expenses are clearly better.

Dele's first shortlist included a driver app that only handled self-employment. It would have needed a second product for the flat. He chose a product from HMRC's list that supports both, created two businesses, and now sends eight quarterly updates a year. This illustrative example is simplified and ignores other income and personal circumstances.

Common mistakes and what each can trigger

• Using profit instead of turnover for the threshold. You may miss your MTD start date, and missed quarterly updates can lead to penalty points. Check the current regime on GOV.UK.
• One combined update for driving and rent. HMRC expects separate updates per business, so your submissions may be rejected or need correcting.
• Mortgage interest coded as an ordinary expense. Your property profit is understated, which can lead to underpaid tax, interest and possible inaccuracy penalties.
• Claiming the £1,000 allowance and expenses together. This is not allowed and HMRC can amend the return, adding tax and interest.
• Recording the whole rent on a joint property. You overstate your income and may be pulled into MTD earlier than necessary.
• Missing 31 January. A late online return attracts a late filing penalty. See GOV.UK's Self Assessment deadlines; registration for a new source is due by 5 October.
