Get your taxes done using TurboTax

I can't see your tax return to tell you why you owe this year versus last year. However, there may be several reasons why you may have a shortfall. The following are some suggestions to help you find the reason why.

  • Double check the amounts you entered into TurboTax to make sure they were entered correctly.
  • Do an income tax return line by line comparison to see what is different this year versus last year.  
  • Your 2020 federal Tax Withholding was lower than 2019.  
  • You deferred less income into your Employer-Sponsored Retirement Plan or Flexible Savings Plan.
  • You didn't qualify for a tax credit you received last year (or the credit amount decreased).
  • You removed a dependent.
  • You changed your filing status.
  • If you itemize, your Itemized Deductions are lower this year. or the standard deduction is lower.
