Making Tax Digital for Income Tax (MTD ITSA): What It Means for You
At our Sunbury-based accountancy practice, proudly supporting clients across Twickenham, Middlesex and Surrey, we are guiding individuals and businesses through one of the most significant developments in the UK tax system: Making Tax Digital for Income Tax Self Assessment (MTD ITSA).
MTD ITSA forms part of the UK government’s wider digital transformation programme led by HM Revenue & Customs (HMRC). If you are self-employed or receive rental income from UK property, these changes are likely to affect you. Early preparation will be essential to ensure compliance and avoid disruption.
Understanding MTD ITSA
Making Tax Digital for Income Tax Self Assessment introduces a new framework for how self-employed individuals and landlords maintain records and report income to HMRC. The traditional once-a-year Self Assessment tax return will be replaced with a system requiring digital record keeping and more regular submissions.
Under MTD ITSA, affected taxpayers will be required to maintain digital records of income and expenses using compatible software. Quarterly updates must be submitted to HMRC summarising income and expenditure for each period. At the end of the tax year, an End of Period Statement (EOPS) will be submitted to finalise business figures, followed by a Final Declaration confirming total taxable income.
The objective of the reform is to improve the accuracy of tax reporting, reduce administrative errors and provide taxpayers with greater visibility over their tax position throughout the year.
Who Will Be Affected?
MTD ITSA will apply to self-employed individuals and landlords whose combined gross income from self-employment and UK property exceeds the relevant threshold set by HMRC. It is important to note that the threshold is based on gross income, not profit, and excludes employment income taxed through PAYE.
The implementation is being phased in according to income levels. Reviewing your latest tax return is the most effective way to determine when the new requirements may apply to you. Our team works closely with clients across Sunbury, Twickenham, Middlesex and Surrey to assess their position and plan accordingly.
What This Means in Practical Terms
In practical terms, paper-based record keeping alone will no longer be sufficient. While spreadsheets may still be used in certain circumstances, they must be linked to HMRC-compatible software to ensure digital compliance.
Instead of submitting a single annual tax return, taxpayers within MTD ITSA will provide quarterly updates during the year. These updates are summaries rather than full tax calculations, but they represent a significant shift in reporting frequency. At year end, the EOPS and Final Declaration will complete the compliance process, effectively replacing the current Self Assessment submission.
For many businesses and landlords, this will require adjustments to bookkeeping processes, internal systems and timelines.
Potential Benefits of Digital Reporting
Although the transition to quarterly digital reporting may appear demanding, there are tangible benefits. Digital record keeping can provide improved visibility of income and expenses, allowing for more accurate forecasting and better-informed financial decisions. Regular updates reduce the likelihood of errors accumulating over a twelve-month period, and many clients find that modern accounting software improves efficiency once fully implemented.
With the right guidance and systems in place, MTD ITSA can become an opportunity to strengthen financial management rather than simply a compliance obligation.

Frequently Asked Questions
When does MTD ITSA come into effect?
The start date depends on your qualifying gross income from self-employment and/or property. The rollout is phased by income level. We recommend reviewing your most recent Self Assessment figures to determine your likely commencement date.
Will I still submit a tax return?
The traditional Self Assessment return will be replaced by a Final Declaration submitted after the end of the tax year. However, quarterly updates will also be required throughout the year.
What income counts towards the threshold?
Gross income from self-employment and UK property rental is included. Employment income taxed through PAYE is not counted towards the MTD ITSA threshold.
Do I need specific software?
Yes. HMRC requires the use of compatible digital software. We advise clients on suitable platforms and provide full implementation and training support.
What are the consequences of non-compliance?
Failure to meet MTD ITSA obligations may result in penalties under HMRC’s points-based system. Timely preparation significantly reduces this risk.
Does this apply if I only have one rental property?
If your gross rental income exceeds the relevant threshold, MTD ITSA will apply regardless of the number of properties owned.
Will compliance increase my accounting costs?
While quarterly reporting increases submission frequency, efficient digital systems often reduce time spent on year-end corrections. We offer flexible service packages tailored to different business needs.
