Tips for next year

You can avoid future problems by:

  • keeping accurate and full records
  • waiting until you get all of your income statements to file your tax return
  • checking the documents you get from your employer, mortgage company, bank, or other sources of income (W-2s, 1098s, 1099s, etc.) to make sure they're correct
  • including all your income on your tax return
  • following the instructions on how to report income, expenses, and deductions
  • filing an amended tax return for any information you receive after you've filed your return

Consider filing your taxes electronically. Filing online can help you avoid mistakes and find credits and deductions that you may qualify for. In many cases you can file for free. Learn more about how to file electronically.
