Reporting interest income

[ellieandelvis]

If you have interest income, you have to upgrade Turbo Tax. My interest income in 2021 was $4.52. If I choose not to upgrade, what will happen by not reporting $4.52 in interest income? Will I be taxed on that later with penalties? Or is there any consideration for such a low amount of interest income?

[DoninGA]

With an amount of interest less than $10 it is doubtful the amount would change the taxes on your taxable income.  

Do not worry about this low amount of interest.

If that is the only interest you have and the ONLY reason for upgrading  then simply ignore that small amount since the IRS will as well.
