Income Tax Before Credits -- line 40, Form 1040; line 23, Form 1040A; line 7, Form 1040EZ. 35. Income Subject to Tax -- For taxpayers filing current year returns, "income subject to tax" is identical to taxable income except for those upper income taxpayers paying 28% average and marginal tax and those dependents paying "kiddie" tax from Form 8615. For the upper income taxpayers the deduction for personal exemptions is phased out and their "income subject to tax" becomes taxable income plus the exemption amount. For dependents filing Form 8615 (TXST = 5 or 6), this is the income taxed at child's rate. For prior year returns, "income subject to tax" is computed by using the tax rate schedule to impute a hypothetical taxable income amount necessary to yield the given amount of tax reported. 36. Marginal Tax Base -- This is the amount of income subject to tax at the highest tax rate applicable to the return (TXRT), using the 1990 Tax Rate Schedules for all returns. 37.
