5 HMRC Changes Every Business Owner and Landlord Should Know in 2026
For UK business owners and landlords, 2026 brings some of the most significant tax administration changes in recent years. HMRC's continued move towards digital tax reporting, combined with increased compliance activity and changing reporting requirements, means it's more important than ever to stay informed.
Understanding these changes now can help you avoid penalties, improve efficiency, and ensure your finances remain compliant throughout the year.
1. Making Tax Digital (MTD) for Income Tax Is Now Mandatory for Many Taxpayers
The biggest change in 2026 is the launch of Making Tax Digital (MTD) for Income Tax.
From 6 April 2026, sole traders and landlords with qualifying income exceeding £50,000 must comply with MTD requirements. The threshold will reduce to £30,000 from April 2027 and £20,000 from April 2028, bringing many more taxpayers into scope.
Under the new system, affected taxpayers must:
Keep digital records.
Use HMRC-compatible software.
Submit quarterly updates to HMRC.
Complete a final year-end declaration.
Importantly, the threshold is based on gross income from self-employment and property income, not profit.
How JSB Accountants Can Help
At JSB Accountants, we can:
Review whether you fall within the MTD thresholds.
Recommend suitable accounting software.
Assist with software setup and migration.
Manage your quarterly submissions on your behalf.
Provide ongoing support to ensure compliance.
By preparing early, you can avoid the stress of last-minute changes and ensure a smooth transition to digital reporting.
2. Quarterly Reporting Is Replacing Annual Tax Administration
Many sole traders and landlords have traditionally focused on their bookkeeping once a year, MTD changes that approach.
Affected taxpayers will now need to submit updates every quarter, with the first submission generally due by 7 August 2026.
While quarterly updates are not tax payments, they do require:
More frequent record keeping.
Up-to-date bookkeeping.
Better visibility of business performance throughout the year.
Businesses that maintain accurate records regularly often benefit from improved cash flow management and fewer surprises at year-end.

3. HMRC Is Increasing Compliance Checks and Data Matching
HMRC continues to expand its use of technology and third-party data to identify inaccuracies and undeclared income.
Particular areas of focus include:
Property income.
Online trading and side businesses.
Construction Industry Scheme (CIS) compliance.
Overseas income.
Cryptoasset transactions.
As HMRC receives increasing amounts of information from external sources, discrepancies are becoming easier to identify.
How JSB Accountants Can Help
We can help by:
Reviewing your tax position for potential risks.
Ensuring all income sources are reported correctly.
Assisting with voluntary disclosures where necessary.
Supporting clients during HMRC enquiries and compliance checks.
Taking proactive action is often far less costly than dealing with issues after HMRC has identified them.
4. Digital Record Keeping Is No Longer Optional
The days of relying solely on paper records and spreadsheets are gradually coming to an end.
MTD requires digital record keeping, and many businesses are now adopting cloud-based accounting systems to meet compliance requirements and improve efficiency.
Benefits include:
Improved accuracy.
Faster access to financial information.
Reduced administrative burden.
Better decision-making through real-time reporting.

5. Businesses Must Continue Planning for Rising Employment Costs

This makes it increasingly important to review:
Payroll structures.
Director remuneration strategies.
Cash flow forecasts.
Tax-efficient planning opportunities.
Regular reviews can help businesses minimise unnecessary costs while remaining fully compliant.
