Making Tax Digital for Income Tax: What Sole Traders and Landlords Need to Know Right Now

If you're self-employed or you earn rental income, the way you report your finances to HMRC has fundamentally changed. Making Tax Digital for Income Tax (MTD for IT) is no longer a future concern — it's here. From 6 April 2026, sole traders and landlords with qualifying income above £50,000 are legally required to comply. And within the next two years, that threshold drops significantly, bringing hundreds of thousands more people into scope.

This isn't just an administrative tweak. MTD for Income Tax represents the most significant change to how self-employed people interact with HMRC since Self Assessment was introduced in 1996. Understanding exactly what's required, when it applies to you, and how to get set up correctly will save you from headaches, penalties, and last-minute panic.

What Is Making Tax Digital for Income Tax?

Making Tax Digital for Income Tax replaces the traditional annual Self Assessment tax return process with a system of ongoing, digital record-keeping and quarterly reporting. Instead of summarising a year's income and expenses in one go each January, you'll now maintain digital records throughout the year and submit four updates to HMRC — one for each quarter of the tax year.

At the end of the year, you'll also submit an End of Period Statement and a Final Declaration (which effectively replaces the Self Assessment return), confirming your income and making any necessary adjustments. The aim of the system, at least from HMRC's perspective, is to reduce errors that arise from annual record-keeping and to give both taxpayers and the government a clearer, more up-to-date picture of tax liabilities.

Who Does It Apply To, and When?

MTD for Income Tax is being rolled out in phases, based on the level of your qualifying income. Qualifying income means your combined gross income from self-employment and property — before any expenses are deducted.

• From 6 April 2026: Sole traders and landlords with qualifying income over £50,000 must comply.

• From 6 April 2027: The threshold drops to £30,000.

• From 6 April 2028: Anyone with qualifying income over £20,000 will be brought into the regime.

Whether you're caught by the April 2026 mandate depends on your income for the 2024/25 tax year. If your gross self-employment and property income for that year exceeded £50,000, you were required to sign up and start operating under MTD from April 2026.

It's worth noting that partnerships are not yet included in the initial rollout — the government has indicated these will follow at a later date. Limited companies are also not in scope, as corporation tax operates under a separate system.

What Are the Quarterly Submission Deadlines?

The tax year for MTD purposes runs from 6 April to 5 April, just as it always has. Within that year, it's divided into four quarters, each with its own submission deadline.

• Quarter 1 (6 April to 5 July): submission due by 7 August

• Quarter 2 (6 July to 5 October): submission due by 7 November

• Quarter 3 (6 October to 5 January): submission due by 7 February

• Quarter 4 (6 January to 5 April): submission due by 7 May

After all four quarterly updates have been submitted, you then need to complete your End of Period Statement and Final Declaration. The deadline for the Final Declaration is 31 January — the same as the current Self Assessment filing deadline — giving you until 31 January 2027 to finalise your 2025/26 affairs under the new system if you were mandated from April 2026.

What Information Do You Need to Submit Each Quarter?

Each quarterly update is a summary of your income and expenses for that three-month period. Crucially, HMRC describes this as a "light touch" submission — you're not required to categorise every transaction in exhaustive detail. The update broadly covers:

• Total turnover or rental income

• Total allowable expenses (split into broad categories)

You won't be calculating your tax bill at this stage. The quarterly updates give HMRC an estimated picture of your income, but the actual tax calculation only becomes final when you submit your End of Period Statement and Final Declaration at the end of the year.

However — and this is where the detail matters — HMRC expects your records to be maintained digitally throughout the year, not reconstructed at quarter-end from a pile of bank statements and receipts. The digital record-keeping requirement is real, and you must be able to demonstrate that records are kept in a qualifying digital format.

What Software Do You Need?

You cannot submit MTD quarterly updates through your HMRC online account. You need compatible software. HMRC maintains a list of approved software products on its website, and these fall into two broad categories.

The first is all-in-one software that handles both your digital record-keeping and the submission of quarterly updates directly to HMRC. Products like QuickBooks, Xero, FreeAgent, and Sage fall into this category, among many others. If you're not already using accounting software, this is the most straightforward route.

The second option is to continue using spreadsheets for your records, but connect them to HMRC via bridging software. This approach can work, but it adds a layer of complexity — you need to ensure the bridge correctly maps your spreadsheet data to the required HMRC fields, and any manual errors in the spreadsheet won't necessarily be caught before submission.

For most people, particularly those above the £50,000 threshold who are likely managing meaningful self-employment income, investing in proper accounting software is the sensible choice. The time saved and the reduction in errors more than justifies the cost, which itself may be tax-deductible as a business expense.

What Are the Penalties for Non-Compliance?

MTD for Income Tax uses a points-based penalty system. Each time you miss a quarterly submission deadline, you accumulate one penalty point. Once you reach four points, a £200 financial penalty is applied. Points expire after a period of good compliance.

There is, however, a transitional concession for those entering the system in April 2026. HMRC has confirmed that penalty points will not be applied for late quarterly updates during the 2026/27 tax year — the first year of the new regime. This is intended to give businesses time to adapt without the fear of immediate financial consequences for minor slips.

Late payment penalties and interest on unpaid tax remain entirely separate and continue to apply in the usual way.

A Practical Example: How MTD Works in Practice

Consider Sarah, a freelance graphic designer based in Manchester. She earns £65,000 a year from her design contracts and has no rental income. Her qualifying income is above £50,000, so she was required to sign up for MTD for Income Tax from 6 April 2026.

Sarah switched to FreeAgent earlier this year. Each time she raises an invoice or pays a business expense, she logs it in the software. At the end of each quarter, she reviews her figures, and her accountant confirms they look correct before the submission is sent to HMRC.

Here's how her first year of quarterly submissions looks:

• Quarter 1 (April to July 2026): gross income £16,000, expenses £2,400. Update submitted by 7 August 2026.

• Quarter 2 (July to October 2026): gross income £17,500, expenses £2,100. Update submitted by 7 November 2026.

• Quarter 3 (October 2026 to January 2027): gross income £14,000, expenses £3,200. Update submitted by 7 February 2027.

• Quarter 4 (January to April 2027): gross income £17,500, expenses £1,900. Update submitted by 7 May 2027.

In October 2027, Sarah and her accountant complete her End of Period Statement, making adjustments for capital allowances and other year-end treatments. The Final Declaration is filed by 31 January 2028, confirming her taxable profit and settling any remaining liability.

Sarah found the transition smoother than she expected — largely because she had proper software in place and an accountant reviewing each submission before it went in. The quarterly rhythm has also given her a much clearer picture of her business finances throughout the year, rather than being surprised at tax time.

Common Misconceptions Worth Clearing Up

Misconception 1: MTD means you pay tax quarterly

Your quarterly updates are informational only. You are not making tax payments four times a year under MTD. Your tax bill is still calculated once a year, based on your Final Declaration, and payment deadlines remain as they are under the current system.

Misconception 2: Only people above £50,000 need to think about this

If your income is currently between £30,000 and £50,000, April 2027 is only 12 months away. Getting your software and processes in order now — rather than scrambling in the spring of 2027 — is by far the better approach. Those with income above £20,000 should also be preparing, as the 2028 mandate will affect a very large number of sole traders across the UK.

Misconception 3: You can continue using spreadsheets without bridging software

Plain spreadsheets alone do not satisfy HMRC's digital record-keeping requirements. If you use spreadsheets, they must be connected to compatible bridging software that can submit data directly to HMRC in the correct format. A spreadsheet you fill in and then re-key manually into another system does not comply.

Steps to Take Right Now

If you're already in scope — or approaching the threshold — there are four practical steps to work through without delay.

First, confirm whether your qualifying income exceeded £50,000 in the 2024/25 tax year. If you're not sure, check with your accountant or look at your most recent Self Assessment return.

Second, choose compatible software and get it set up. Allow time for data migration if you're moving from another system or from manual records.

Third, sign up for MTD for Income Tax through HMRC's online service. You'll need a Government Gateway account and your Unique Taxpayer Reference.

Fourth, establish a quarterly review habit. Whether you work with an accountant or manage your own books, build in time each quarter to review your figures before the submission deadline arrives.
