Why is my federal refund negative?

That means you have tax due and are not getting a refund.   You will need to pay your tax due by April 18, 2023.

 

Please look at your Form 1040----if you owe federal tax is it on line 37.

Click on Tax Tools on the left side of the screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

That is a tax due.  You owe.  Basically your withholding and any credits were not enough to cover the tax on your income.  Review each line on your tax return and maybe compare it to last year.  If you don't understand an amount post back.

 

Before filing,  You can preview the 1040 or print the whole return
