I know there are a lot of Indians doing a lot of stuff on Bing ads promoting affiliate offers and what not. I got an email today from Bing basically saying this: As required by law, Bing Ads will begin charging Goods and Services Tax (GST) from 1 July 2017, or from the GST effective date announced by the Government. Please update or add your address (including state name), permanent account number (PAN), and GST identification number (GSTIN) to your account prior to 1 July 2017. This information is critical for invoice issuance and transaction reporting with the GST Network, and will be required to access your Bing Ads account in July. To add your address, PAN, and GSTIN to your account, sign into Bing Ads and follow these steps: Click the gear icon , and then click Accounts & Billing. In the Business Location and Tax Information section, click the pencil icon . Enter your address, PAN, and GSTIN. Click Save. I do not have a registered business...is this mandatory for me to get a GSTIN number?
