What documents do I need to include with my tax return?

When filing your tax return with the Oklahoma Tax Commission, it is crucial to include essential documents to ensure accurate processing. The following documents may be required: 1. W-2 forms from each employer for wage and salary income. 2. 1099 forms for any additional income, like freelance earnings or interest. 3. Documentation for deductions, including receipts for itemized expenses, mortgage interest, or medical bills if applicable. 4. Supporting documentation for tax credits, such as education expenses or energy-saving home improvements. 5. A copy of your previous year's tax return if you are a new Oklahoma resident. 6. Any other relevant financial records or paperwork that might affect your tax situation. Remember to double-check specific requirements on the Oklahoma Tax Commission's website or consult a tax professional to avoid any omissions or errors in your tax return.
