As tax returns are accompanied with Laws and regulations, common people are unable to understand the requirements of it and their subsequent consequences if those were disagreed by departments. We professionals can update ourselves on every time and we know the exact requirements. Hence I preferred this section of business. Book Keeping is an art by commerce people which enables the business man to know his business stands at which stage. Financials are most demanded set of documents by everywhere. Government Departments demand financials to submit before them. If business go for Loan, Banker will demand Financials to compute business's repayment capability.
