There are many reasons why your refund may have changed from last year. Income and wages, credits and deductions, tax reform, and other factors may cause your tax obligation to change from year to year.
Some common reasons your tax obligation may have changed are:
- Many implications with tax reform going into effect this tax year
- Your filing status changed
- Your income changed
- There were changes to your qualifying dependents
- You chose a standard deduction instead of an itemized deduction
You may want to review this year's and last year’s returns and compare them to identify any changes. You can also get your IRS transcript to review your return from last year.
