1. Check the sales taxes in your state. All but five states impose sales and use taxes on retail sale, lease, and rental of many goods, as well as some services. Sales tax is calculated as the purchase price times the appropriate tax rate. Tax rates vary widely from less than one percent to over ten percent. Sales tax is collected by the seller at the time of sale.
  2. File your tax return. Filing your tax return is more than an obligation: it's also a duty and responsibility of citizenship. You may receive tax forms in the mail, or pick them up at the local Post Office or library. Fill the forms in and then mail or electronically send completed tax forms and any necessary payments to the Internal Revenue Service (IRS) and your state's department of revenue. The IRS provides free resources to help people prepare and electronically file their tax returns; go to IRS.gov to learn more. Note: certain things such as charitable donations and business expenses are tax deductible.
