📢 Important Compliance Alert: Daily Backup of Books of Account Mandatory from 1 April 2026
Businesses maintaining books of account in electronic mode should take note of the compliance requirements under Rule 46(8) of the Income-tax Rules.
The Rule provides that:
“The books of account and other documents maintained in electronic mode shall remain accessible in India at all times, and the back-up of such books of account and other documents maintained in electronic mode shall be kept in servers physically located in India, and shall be updated on a daily basis.”
What does this mean for businesses?
✅ Books maintained electronically must remain accessible within India.
✅ Backup servers must be physically located in India.
✅ Backup data must be updated on a daily basis.
Practical Action Points
🔹 Obtain written confirmation from your software vendor or cloud service provider regarding the location of primary and backup servers.
🔹 Implement an automated daily backup mechanism.
🔹 Maintain backup logs and evidence of successful completion.
🔹 Include Rule 46(8) verification in year-end compliance reviews and tax audit checklists.
Special Attention for TallyPrime Users
If your books are maintained on TallyPrime, ensure that:
✔ Your cloud hosting provider maintains India-based backup servers; or
✔ A separate automated backup process is configured on an India-based server.
For Housing Societies, MSMEs, LLPs & Companies
I recommend implementing a formal Backup & Data Retention Policy and retaining monthly evidence of compliance.
This may soon become a routine verification point during:
• Tax Audits
• Assessments
• Departmental Inquiries
• Litigation Proceedings involving digital books of account
Businesses that act early will be better prepared to demonstrate compliance and avoid unnecessary disputes.
📌 If your organization maintains books electronically, now is the right time to review your data storage and backup architecture before FY 2026-27 begins.
