Thank you for contacting Facebook. My name is Hannah and it's my pleasure to assist you today.
Starting in 2019, Facebook will collect value-added tax (VAT) on the sale of ads to individuals and businesses based in the Russian Federation. Collection of VAT related to advertising (eServices) is driven by recent changes in Russian tax law.
Future invoices and charges will be subject to local VAT. If you are registered with the appropriate local tax authority, this tax will likely be creditable. Given this change, it is important to have your most current Personal Tax Payer ID (INN) on file in order to reclaim VAT.
