Rule 46(8) Income Tax Rules 2026: Mandatory Daily Backup of Digital Books of Account

Effective 1st April 2026, a new compliance requirement under Rule 46(8) of the Income-tax Rules 2026 mandates that every person maintaining their books of account in electronic form must create a daily backup of their data. This rule is particularly relevant for businesses using cloud-based accounting software or servers hosted outside India.

What does Rule 46(8) require? Any person whose books of account are maintained electronically must ensure that a backup is created each day. If the data is stored on a server outside India, the backup must also be kept on a server within India. The rule aims to ensure that tax records are accessible and preserved for audit and scrutiny purposes under the new Income Tax Act 2025.

Who does this apply to? The rule applies to all businesses, professionals, and individuals required to maintain books of account under the Income Tax Act. This includes companies using popular cloud-based accounting platforms where servers may be located abroad, making India-based backup compliance particularly critical.

Penalties for non-compliance: Failure to comply with Rule 46(8) can attract penalty proceedings under the Income Tax Act 2025. Non-compliance during a tax scrutiny or survey could also raise red flags with the Assessing Officer.

Practical steps to comply: First, check where your accounting software stores data. If it is on overseas servers, ensure your provider offers an India-based data residency option or set up a local backup process. Second, configure automated daily backups and maintain backup logs. Third, ensure backups are retrievable and readable for tax audit purposes.

This new rule affects users of Tally offline, QuickBooks, Zoho Books, and similar platforms. SpotOn Business Solutions LLP can help you assess your current setup and build a compliant digital bookkeeping process. Contact us today.
