## What’s Changing and Who’s Affected Making Tax Digital (MTD) for Income Tax has become **mandatory from 6 April 2026** for individuals with self-employment or property income that exceeds £50,000 in the previous tax year. This means that instead of only submitting a Self Assessment once per year, you’ll also be required to submit **quarterly updates** of income and expenses using **compatible software**. ([gov.uk](https://www.gov.uk/government/collections/making-tax-digital-for-income-tax?utm_source=openai)) If your qualifying income (turnover before expenses) was over £30,000 in 2025-26, or over £20,000 in 2026-27, you'll join mandatory MTD in later years. ([gov.uk](https://www.gov.uk/guidance/use-making-tax-digital-for-income-tax/before-you-use-this-guide?utm_source=openai)) ## Key Deadlines & Milestones * **7 August 2026**: Submit your **first** quarterly update covering the period from 6 April to 5 July 2026. ([gov.uk](https://www.gov.uk/government/news/deadline-approaches-for-first-making-tax-digital-quarterly-update?utm_source=openai)) * After that, updates are due by **7 November 2026**, **7 February 2027**, and **7 May 2027**. ([makingtaxdigital.campaign.gov.uk](https://makingtaxdigital.campaign.gov.uk/quarterly-updates/?utm_source=openai)) * The annual Self Assessment return still due by **31 January 2027**, and includes all income, reliefs, and other sources. ([makingtaxdigital.campaign.gov.uk](https://makingtaxdigital.campaign.gov.uk/quarterly-updates/?utm_source=openai)) ## Practical Steps to Get Ready 1. **Check if you fall in scope**: If your self-employment income + property income in 2024-25 exceeded £50,000, you’re required from April 2026. If you don’t yet exceed that, prepare ahead. ([gov.uk](https://www.gov.uk/guidance/use-making-tax-digital-for-income-tax/before-you-use-this-guide?utm_source=openai)) 2. **Select compatible software**: Ensure your accounting/book-keeping solution is MTD-ready and can generate updates & keep digital records. Keep up-to-date with software finds on GOV.UK. ([gov.uk](https://www.gov.uk/government/collections/making-tax-digital-for-income-tax?utm_source=openai)) 3. **Create digital records**: From the start of the new tax year (6 April 2026 or your accounting calendar equivalent), start logging every income and expense in software by date, category and amount. Supporting docs still need to be kept offline. ([gov.uk](https://www.gov.uk/guidance/use-making-tax-digital-for-income-tax/create-digital-records?utm_source=openai)) 4. **Quarterly updates**: For each 3-month period, total your income and expenses and submit the update by the deadline. It’s not a full tax return but contributes to forecasting your liability. ([makingtaxdigital.campaign.gov.uk](https://makingtaxdigital.campaign.gov.uk/quarterly-updates/?utm_source=openai)) 5. **Watch for penalties in years ahead**: For 2026-27, HMRC will not issue penalty points for missed quarterly updates. That changes for **future years**, where late or missed updates accrue points which may lead to fixed-penalty charges after several misses. ([gov.uk](https://www.gov.uk/government/news/deadline-approaches-for-first-making-tax-digital-quarterly-update?utm_source=openai)) ## Common Pitfalls & Tips to Avoid Them * **Underestimating software changes**: Some accounting tools default to accounting period 6 April–5 April; if your business uses calendar year, you’ll need to change software settings before submitting your first update. ([gov.uk](https://www.gov.uk/government/publications/agent-update-making-tax-digital-for-income-tax/agent-update-making-tax-digital-for-income-tax--2?utm_source=openai)) * **Mixing up income sources**: You must include income from property and self-employment. If you also receive dividends, pensions, or employment income, these still go on your annual SA return. ([gov.uk](https://www.gov.uk/guidance/use-making-tax-digital-for-income-tax/add-or-cease-income-sources?utm_source=openai)) * **Starting or stopping incomes mid-year**: If you begin a self-employment or property income source during the year, you’ll need to report it in the upcoming return and begin quarterly updates later for certain thresholds, unless you opt in earlier. ([gov.uk](https://www.gov.uk/guidance/use-making-tax-digital-for-income-tax/add-or-cease-income-sources?utm_source=openai)) ## Example Sarah runs a small B&B (self-employment) and let’s out one holiday cottage (property income). In 2024-25 she made £35,000 from the B&B and £20,000 from the cottages—so £55,000 qualifying income. She must use MTD from April 2026. Sarah buys software, starts logging income & expenses from 6 April, submits her first quarterly update by 7 August, then the second by 7 November, etc. In January 2027, she also submits her full SA tax return that includes dividend income she gets from investments, even though that was outside her MTD income sources. ## Bottom Line MTD for Income Tax marks a major shift to continuous reporting. If you’re in scope now, the key is **software, record-keeping, and meeting quarterly deadlines**. Get ahead this tax year to make future years smoother—and avoid surprises. With proper preparation, what seems a burden now becomes part of good practice for business and tax hygiene.
