Stay updated with HMRC changes for April 2026. Understand MTD rules, key deadlines, penalties, and allowances to stay compliant.
April marks the start of a new tax year, and with it come important updates from HMRC. For many taxpayers, especially those under the Construction Industry Scheme (CIS) and self employed individuals, these changes can feel difficult to keep up with.
Understanding the latest updates around Making Tax Digital (MTD), deadlines, penalties, and allowances will help you stay compliant and avoid unnecessary costs.
This guide explains the key changes in simple terms so you know what to expect and what action to take.
What has changed for April 2026
At the start of the new tax year, HMRC introduces updates that affect how income is reported and how tax is calculated.
While not all rules change every year, it is important to review:
• Reporting requirements under Self Assessment
• Progress towards Making Tax Digital for Income Tax
• Updated thresholds and allowances
• Compliance expectations from HMRC
Staying informed early in the tax year helps you avoid surprises later.
Making tax digital updates
Making Tax Digital for Income Tax continues to move forward, affecting how many taxpayers will report their income.
Key points to understand include:
• Requirement to keep digital records of income and expenses
• Use of compatible software for reporting
• Quarterly updates submitted to HMRC
• A final end of year declaration replacing the traditional approach
Although full implementation may not apply to everyone immediately, preparing early is strongly recommended.
Key deadlines you should not miss
Understanding deadlines is essential to avoid penalties.
Important dates include:
• 5 April as the end of the tax year
• 6 April as the start of the new tax year
• 31 January for Self Assessment submission and payment
Missing deadlines can result in penalties and interest charges, so it is important to stay organised.
Understanding HMRC penalties
HMRC applies penalties when taxpayers fail to meet their obligations.
Common reasons for penalties include:
• Late submission of Self Assessment returns
• Late payment of tax
• Inaccurate or incomplete information
• Failure to keep proper records
Under newer systems, penalties may also apply to late updates under MTD.
Staying organised and accurate can help you avoid these issues.
Allowances and what to review
At the start of the tax year, it is important to review available allowances.
These may include:
• Personal allowance for income
• Dividend allowance for company directors
• Allowable expenses for self employed individuals
• Capital allowances for business assets
Using these correctly can reduce your overall tax liability.
What CIS workers should be aware of
For those working under CIS, April is a key time to review tax matters.
You should ensure:
• CIS deduction statements are accurate
• Income and expenses are properly recorded
• Your Self Assessment is prepared correctly
• You are ready to claim any refund due
Good organisation at the start of the tax year can make a big difference.
