What forms should you use to file your tax return?

To file your tax return, you should typically use Form 1040 for individual income tax returns in the United States. Depending on your specific situation, you may also need to include additional schedules or forms, such as Schedule A for itemized deductions or Schedule C for business income. If you are self-employed, you might need to file Form 1040 and Schedule SE for self-employment tax. Always ensure to check the IRS guidelines for any updates or specific requirements based on your financial situation.
