It is too late to file an amended return for 2016.
What is the deadline to amend 2016 tax return?
April 15, 2020, Based on the three-year rule, you have until April 15, 2020, to file an amended 2016 return and claim your refund.
The following is from your State:
How Long Do You Have to File an Amended Return?
- If you or the IRS changes your federal return, you must file an amended Virginia return within one year of the final IRS determination.
- If you file an amended return with any other state that affects your Virginia income tax, you must file an amended Virginia return within one year.
Interest on any amount due will still accrue from the original due date, so file the corrected return as soon as you can.
We can only issue a refund if the amended return is filed within:
- 3 years from the due date of the original return, including valid filing extensions; (last day to file 2016 amended return is April 15, 2020)
- 1 year from the final determination of the amended federal return or federal change, whichever is later, provided that the allowable refund is not more than the decrease in Virginia tax attributable to the federal change or correction;
- 1 year from the final determination of the amended return of any other state, or change or correction in the income tax of the taxpayer for any other state, provided that the refund does not exceed the amount of the decrease in Virginia tax attributable to such change or correction;
- 2 years from the filing of an amended Virginia return resulting in the payment of additional tax, provided that the current amended return raises issues relating solely to the prior amended return and that the refund does not exceed the amount of the tax payment made as a result of the prior amended return; or
- 2 years from the payment of an assessment, provided the amended return raises issues relating only to the prior assessment and the refund does not exceed the amount of tax paid on the prior assessment.
