Starting July 1, 2017, Adobe is required to charge 18% GST on all goods and services in accordance with India laws. This is an increase over the 15% tax rate applicable prior to July 1, 2017. For more information on GST, visit the GST - Goods and Services Tax page.
If you have a paid monthly plan, you will see the GST on your statement at the next billing on or after July 1, 2017. If you have a prepaid annual plan with a commitment period starting prior to July 1, 2017, the GST goes into effect at the end of your annual term.
This change does not affect the base price of your Adobe subscription or membership.
