Principles of Taxation Chapter 13 The Individual Tax Formula
Objectives • filing status • computing taxable income • standard deduction versus itemized deductions • exemptions • tax rates • credits and AMT • payment and filing requirements
Filing Status - Married • If married on the LAST day of the year. • MFJ (married filing joint) rates • If spouse incomes very similar, single rates generate lower tax • If spouse incomes dissimilar, married rates generate lower tax. • MFJ rates apply to Surviving Spouse • widow or widower with a dependent child for 2 more years after death of spouse. • MFS (married filing separately) rates are less favorable. Typically used by separated spouses.
Filing Status - Unmarried • Single is the default category for unmarried individuals (neither surviving spouse nor head of household). • SeeAP1 for filing status examples.
Taxable Income Computation • Calculate total income totalling Line 22 on 1040. • Calculate Adjusted Gross Income (AGI) on Line 32 of 1040. • Subtract the greater of: • standard deduction or • itemized deductions • Subtract total exemptions
Standard Deduction • Depends on filing status. For 1999: • MFJ = $7200 • MFS = $3600 • HOH = $6350 • Single = $4300 • Blind or aged (>=age 65) • MJF, MFS = $850 per item • HOH or Single = $1050 • See AP2 for standard deduction examples.
Itemized deductions • See Schedule A (Chapter 16 details) • Bunching. If itemized deductions are about equal to standard deduction each year, bunch deductions on alternate years and claim standard deduction on other years. • Example: My dad gives $5,000 to charity each year. He is 72 and single. What is his standard deduction each year? Does he itemize? Suppose he gave $10,000 to the church every other year?
Exemptions • Personal exemption for the taxpayer (2 for MFJ). • You cannot claim yourself if someone is claiming you. • Exemption = $2750 in 1999 for each personal or dependency exemption.
Exemptions for dependents • Family member OR live in your home for entire year. • You provide > 1/2 financial support • Dependent’s gross income < exemption amount • waived for child < 19 OR student-child<24. • Dependent may not generally file a joint return. • Dependent must be a U.S. citizen OR a resident of US, Mex, Can • See AP3 for practice with rules.
Rich People • Phase-out of itemized deductions - If AGI greater than $126,600 (MFJ) in 1999, itemized deductions are reduced by 3% of income > $126,600. Can’t reduce itemized deductions below 20% of the total. • Phase-out of exemptions - IF AGI greater than $189,950 (MFJ) in 1999, reduce exemption by 2% for each $2500 that AGI is above the threshold. Can reduce to 0.
Tax Formula • Total Income - Adjustments = AGI - stand ard or itemized deductions- exemp tions= Taxabl e Income • Take Tax able Income to the rate schedules at the front of the book.
Tax computations • See AP 4 and 5 for practice with tax rate schedules. What do you notice about married versus single rates? • AP4 Would Ms. G and Mr. H prefer married or single? • AP5 Would Mr. P and Mrs. P prefer married or single?
Credits • Child Credit = $500 per child in 1999. Phases out for rich. • Dependent care credit (child < 13 years old). Credit amount between 30% and 20% of child care costs depending on income range. • Earned income credit. This is refundable - a transfer payment to working poor. Increases progressivity of tax rates. Credit is higher for taxpayers with children and phases out as income increases. • Excess FICA withholding is refunded through a tax return claim.
AMT (again!!) • Same purpose - make sure rich people using “loopholes” pay some tax. • Taxable income+ or - adjustments+ preferences= AMTI before exemption- exemption= AMTIx 26% or 28%= TMT
Payment and Filing Requirements • Taxes on wages are withheld each pay period. • Estimated taxes on other income due 4/15, 5/15, 9/15 and 1/15. • Pay 90% of current year tax, 100% of prior year (or 105% of prior year if 1998 AGI>$150,000). • Tax return due 4/15, but may be extended to 8/15 then 10/15 (LAST DATE).
