In the Ad Accounts Settings of Ads Manager, you can check the box to confirm whether or not you’re advertising for business purposes and responsible for self-assessing and paying VAT in accordance with the Tax Code of Kenya. If you confirm you’re advertising for business purposes, Facebook doesn’t add VAT to your purchase of Facebook ads. VAT is added whenever you’re charged for your ads if you’re not purchasing Facebook ads for business purposes. Because VAT is added on top of charges, you won’t reach your billing threshold faster, but you may be charged more than your billing threshold amount. If you pay for Facebook ads with a manual payment method, VAT is accounted for and applied at the applicable local rate when your ad account is funded to determine the total balance available.
