Do I need to refile if I already filed but received a 1099-G for less ($356) than what I put as my 2016 state refund ($466).

[HelenaC · Accepted solution]

No, you don't have to file an amended income tax return, unless you want to. 

• By adding a higher state refund amount, you are probably paying a few more dollars in taxes than you would have, had you claimed the correct amount of $356. 
• The IRS does not worry about you paying too much taxes. They worry when you pay too little taxes.

To see what difference the $110 makes, you can prepare a "dummy" amended income tax return. 

• Make sure you wait until you receive your 2017 refund before making any changes and delete it after you are done. 
• If you don't delete,the wrong information will carryover to your 2018 income tax return.
