Business Categories for Taxes (BCT) is a system of classifying businesses according to their primary activity, with the purpose of determining the amount of tax they must pay. This process allows taxation authorities to accurately assess and collect taxes from businesses based on their activities. Each business is assigned one or more BCTs and these categories are used for both the national level classification of businesses in the United States, as well as the international standardization of businesses across multiple countries. With the help of the BCT system, businesses can easily calculate their taxes accurately, while taxation authorities can efficiently track activities and prevent tax evasion. So, whether you’re an accountant or a business owner, BCT is here to ensure that everyone pays their fair share!
