If you are a sole trader earning over £50,000, HMRC is about to fundamentally change how you report your taxes.
From April 2026, the era of the annual tax return panic is ending. Instead, you must submit quarterly updates to HMRC using approved software. If you miss a deadline, you face fines.
I have spoken to hundreds of sole traders who have no idea this is coming. Some think it only affects VAT-registered businesses, while others believe their accountant will simply “sort it out” without any input from them. Both assumptions are wrong.
In this guide, I will explain exactly what Making Tax Digital (MTD) means for you, when you need to act, and the steps you must take to avoid penalties.
The Shift to Digital Reporting
Making Tax Digital is HMRC’s plan to move the UK tax system away from paper records and manual submissions towards digital records and software-based reporting. You have probably already experienced MTD for VAT if you are VAT registered. Now, HMRC is rolling this out to Income Tax.
The key change is significant. Instead of submitting one Self Assessment tax return per year, you will need to submit quarterly updates throughout the year using approved software. HMRC will no longer accept paper returns or their online portal for those within scope.
Who Is Affected and When?
MTD for Income Tax applies to sole traders and landlords. The rollout is happening in stages based on your gross turnover (income before expenses), not your profit.
- April 2026: Turnover over £50,000.
- April 2027: Turnover over £30,000.
- April 2028: Turnover over £20,000.
The New Obligations: 4 Quarterly Updates
Under MTD, the single annual deadline disappears. Instead, you must complete four specific tasks every year.
- Keep Digital Records: You must maintain digital records of your income and expenses using HMRC-approved software. Spreadsheets are only acceptable if you connect them to “bridging software” that can submit data to HMRC.
- Submit Quarterly Updates: Every three months, you must submit a summary of your income and expenses. These are not full tax returns, just simple summaries from your software. The deadlines are fixed at the 7th of August, November, February, and May.
- Submit an End of Period Statement (EOPS): After the tax year ends, you finalize your figures. This is where you confirm allowable expenses and apply capital allowances.
- Submit a Final Declaration: This replaces your current tax return. It confirms all your income, including sources like bank interest or dividends, and calculates your final tax position.
Will You Pay Tax More Often?
This is a common concern, but the answer is no. MTD does not mean paying tax quarterly.
You still pay Income Tax through the normal Self Assessment deadlines (January and July). The quarterly submissions are for reporting only. You are giving HMRC visibility of your figures throughout the year, but you are not settling a tax bill each quarter.
However, understanding your numbers throughout the year becomes more important because it eliminates surprises in January.
The Cost of Missing Deadlines
HMRC is introducing a new points-based penalty system. You receive one penalty point for each late quarterly update. Once you accumulate four points, you receive a £200 fine. Every additional late submission after that triggers another £200 penalty.
There is some good news for the first wave of mandated businesses. If you join in April 2026, HMRC will not issue penalty points for late quarterly updates during the first year (2026/27). This gives you a “soft landing” to get used to the system. However, this grace period does not apply to your Final Declaration.
Software Is No Longer Optional
You need HMRC-recognized software that can submit directly to HMRC. Crucially, HMRC will not provide free software for this. You must choose a commercial product like Xero, QuickBooks, or FreeAgent.
Many sole traders make the mistake of choosing software that is technically compliant but not practical for their daily work. For example, ecommerce sellers need software that handles marketplace integrations, while landlords need something designed for property income.
The Bottom Line
MTD for Income Tax is coming whether you like it or not. The businesses that start preparing now will have a smooth transition, while those who ignore it until the last minute will face stress, confusion, and penalties.
The quarterly updates themselves are not complicated. The real challenge is having your digital records in order to produce them. That is what you need to focus on now.
