Are you ready for Making Tax Digital for Income Tax? 

Making Tax Digital for Income Tax (MTD for IT) represents a major change to how self-employed individuals and landlords report their income to HMRC. The new system will be introduced in stages from April 2026, and early preparation is essential. 
 
Under MTD for IT, affected taxpayers will need to: 
 
Keep digital records 
Submit quarterly updates to HMRC 
Use MTD-compatible accounting software 
Comply with a new points-based penalty regime 
 
When does MTD for IT apply? 
 
Your start date depends on your qualifying income, which is your total income from self-employment and property before expenses: 
 
From 6 April 2026 – qualifying income over £50,000 (2024–25 tax year) 
From 6 April 2027 – qualifying income over £30,000 (2025–26 tax year) 
From April 2028 – qualifying income over £20,000 (2026–27 tax year) 
 
Exemptions 
 
You may be exempt if: 
 
Your qualifying income is £20,000 or less 
You meet automatic exemption criteria (age, disability, or location) 
You successfully apply to HMRC due to digital exclusion 
 
If MTD for IT does not apply to you, you must continue reporting income through Self Assessment where required. 
 
Bidwell Accountancy can help you assess your start date, select suitable software, and ensure you’re fully prepared well before MTD becomes mandatory. 
 

Changes to Agricultural and Business Property Relief 

The government has announced revisions to the planned reforms to Agricultural Property Relief (APR) and Business Property Relief (BPR), effective from 6 April 2026. 
 
Key changes include: 
 
The threshold for 100% relief increasing from £1 million to £2.5 million 
Relief reduced to 50% on qualifying assets above £2.5 million 
Married couples and civil partners able to pass on up to £5 million of qualifying assets free from inheritance tax, in addition to existing nil-rate bands 
 
The transferable allowance will also apply to surviving spouses or civil partners widowed before the policy announcement. 
 
These revisions significantly reduce the impact on small farms and family-owned businesses. The government estimates that around 85% of estates claiming APR in 2026–27 will pay no additional inheritance tax. 
 
Shares traded on AIM and other “not listed” markets will attract BPR at 50%, reduced from 100%, from April 2026. 

Selling a second property? Don’t overlook Capital Gains Tax 

 
Capital Gains Tax (CGT) often applies when selling property that is not your main residence, and strict reporting deadlines apply. 
 
CGT is commonly payable on: 
 
Buy-to-let properties 
Second or holiday homes 
Business premises 
Land 
Inherited property (based on post-inheritance growth) 
 
The annual CGT exemption is £3,000, with most residential property gains taxed at 24%. Some gains may be taxed at 18% where income remains within the basic rate band. 
 
The 60-day rule 
 
Any CGT due on the sale of UK residential property must usually be: 
 
Reported via a UK Property CGT return 
Paid within 60 days of completion 
 
Missing this deadline can result in penalties and interest. Early advice can help you calculate liabilities accurately and avoid unnecessary costs. 

Construction Industry Scheme: tougher action on fraud 

New measures aimed at tackling fraud within the Construction Industry Scheme (CIS) will take effect from 6 April 2026. 
 
Where HMRC believes a business knew, or should have known, a payment was connected to fraud, it will be able to: 
 
Withdraw Gross Payment Status (GPS) immediately 
Assess the business for tax losses 
Impose penalties of up to 30% 
 
Businesses that lose GPS due to fraud or serious non-compliance will be barred from reapplying for five years, up from the current one-year restriction. 
 
Additional planned CIS changes include: 
 
Exempting payments to local authorities and certain public bodies 
Reintroducing the requirement for contractors to submit nil returns 
 
These changes are intended to strengthen compliance while simplifying administration for legitimate businesses.
