ISIS group offers services for registering businesses and establishments for value-added tax (VAT), filing periodic tax returns, reviewing tax returns, and keeping tax records. Regarding VAT, It is a general tax that is applied to purchases made by the final consumer of a product or service. If you have paid VAT on goods or services used in your professional activity, you may be able to deduct this VAT from the VAT you collect from your customers, as a credit to the government. As a general rule, all sales of products and services are subject to VAT. This means that all transactions you conduct as part of your business are taxed if they are done in exchange for payment and are subject to VAT law and its regulations.
