Tax Reform
Income tax in the U.S. is continually being reformed in hopes of simplifying it.
In 2001, Congress enacted the Economic Growth and Tax Relief Reconciliation Act (EGTRRA):
Reduction in MTRs for all brackets
Reduction in the “marriage penalty”
Increase in child credits, tuition credits, contribution to tax-deferred retirement accounts
Jobs and Growth Tax Relief Reconciliation Act of 2003 accelerated many EGTRRA provisions.
EGTRRA changes will expire at the end of 2010 unless it is renewed by Congress.
Obama Plan
Cut income tax for households with less than $250,000 annual income
Increases in marginal tax rates on the upper 2 percent of income earners
Tax cuts for senior citizens, those without health insurance, first-time homebuyers, and families with college age children
Calculating Taxable Income
Taxable income – portion of income received by individuals that is subject to personal income tax
Gross income – all income received during the year from taxable sources
Adjusted gross income (AGI) – gross income minus any allowable adjustments
Personal exemption – certain sum of money a taxpayer is allowed to deduct from AGI that varies with number of dependents claimed
Standard deduction – fixed dollar amount that is adjusted for inflation each year and varies with filing status of the taxpayer
Itemized deductions – expenses deducted as alternative to the standard deduction from AGI in figuring taxable income
Calculating Taxable Income
