Purpose of Form
What’s New: Change in tax rates. The Tax Cuts and Jobs Act of 2017 has modified the tax rates and brackets that you will use to figure the tax on your 2018 unearned income. Your tax rate is no longer affected by the tax situation of your parents or the unearned income of any siblings. Instead, all net unearned income over a threshold amount of $2,100 for 2018 is taxed using the brackets and rates for estates and trusts. These are shown in the following chart.
