Tax filing refers to the process of submitting tax forms and paying taxes owed to the government. This typically involves gathering all necessary financial information, such as income statements and deductions, and completing the required tax forms for a given tax year.

Once the forms are completed, they are typically submitted to the relevant tax authority, either by mail or electronically. Depending on the jurisdiction and the type of taxes owed, the tax filing deadline can vary, and there may be penalties or interest charges for late filings or payments.

Tax filing can be complex and may require the assistance of a tax professional, especially for individuals or businesses with complicated financial situations.
