The Tax Calculator is an essential tool for business owners to estimate their tax liabilities based on income, deductions, and business structure. By inputting financial information, users can get a clear picture of how much they owe in taxes, helping them plan for payments and avoid surprises at tax time. This tool is particularly important for small business owners who may not have access to a full-time accountant. The calculator helps them make informed financial decisions, manage cash flow, and ensure compliance with tax laws, providing peace of mind throughout the year.
