English translation published by the NBR in its bilingual Regulations file (marked unofficial). The Arabic text published in the Official Gazette remains the legal reference in the event of any discrepancy.
A Taxable Person must notify the NBR, using its prescribed form, of any change to its information, transactions or activities in Bahrain, or any other material information in the registration application, within 30 days from the change.

Updating internal records or another authority does not replace NBR notification. The 30 days run from the change itself, so material changes need an immediate internal escalation route.
