2026 Tax Filing Guide for Small Businesses

Small businesses include sole proprietorships, partnerships, limited liability partnerships (LLPs), and private limited companies with limited turnover. Each structure has distinct filing requirements, but the objective remains consistent: transparent reporting of income, expenses, and tax liabilities.

The purpose of tax filing is not only revenue collection for the government but also financial accountability. Accurate tax filing supports business credibility, access to finance, regulatory compliance, and structured financial planning.
