Is treasury bill gain dividend or interest?

[TaxTheFish]

the form I downloaded from treasuryDirect is 1099-INT. But it gains by purchasing at a discount price, I am not which one it is.

The treasury bill gain would still be considered interest even when purchased at a discount. 

 A dividend is a distribution of earnings from a company to it's shareholders.  The government does not have shareholders nor does it pay dividends. 

So you will enter it in the 1099-INT section by selecting the following:

• Federal
• Income and Wages
• Show More next to Interest and Dividends
• Start next to Interest on 1099-INT
