10. Warm-up: March 4, 2016 All states impose excise taxes on gasoline. According to data from the Federal Highway Administration, the state of California imposes an excise tax of $0.18 per gallon of gasoline. In 2005, gasoline sales in California totaled 15.6 billion gallons. a. What was California’s tax revenue from the gasoline excise tax? b. If California doubled the excise tax, would tax revenue double? Why or why not?

11. D. State income tax (3/4/16) Single Filing Status - 2015

12. E. Other taxes 1. Payroll tax: FICA (Social Security and Medicare) a. Proportional tax: same % regardless of income b. Soc Sec: 6.2% up to $118,500 (up from $117,000 in 2014) - 12.4% total i. Becomes a regressive tax: 2. Medicare: 1.45% (2.9% total) 3. Taxes on corporate profits (progressive)

13. 4. Estate and gift taxes: a. Estate tax: the “death” tax Calendar yearExemptionRate (percentage) 2006$2 million46 2007$2 million45 2008$2 million45 2009$3.5 million45 2010repealed0 2011$5 million35 2012$5.12 million35 2013$5.25 million40 2014$5.34 million40 2015$5.43 million40

15. 5. Sales tax a. Varies by state, county (CA: 7.5%; Alameda Co: 9.5%) b. Tends to be regressive: 6. Property tax a. Depends on value of property – flat percentage b. Helps fund schools c. Proposition 13 (1978):

16. Impact of Prop 13 Average home price in CA, 1975: $41,600 Property taxes paid (1.02%) = $424.32 Value of home cannot increase by more than 2% per year Property taxes 39 years later = 41,600 x (1.02^39) = $901 Value of home for taxation = $90,100 Current average value in 2014 in CA = $424,900 Current property tax for new home = $4333.98 If you keep your 1975 home… Home value increased by 10x, but property tax bill only increased by 2x!

17. Another example: If there was no Prop 13 in California… In the town where I live, median home values have increased 11% from January 2013 to January 2014 Let’s say I bought my home for $1m in 2013 Tax of 1.02% = $10,200 In 2014, my home is re-assessed (increased in value 11%) – now valued at $1.11m Tax of 1.02% = $11,322 2015? $1,232,100 at 1% tax rate = $12,567.42 New Jersey? 2.32% (highest in nation) 2013 – 2014 $1m x 2.32% = $23,200 $1.11m x 2.32% = $25,752

18. 7. Excise taxes a. Tax charged on each unit of a good or service sold b. Famous example: the luxury tax of 1991 c. Other examples: Luxury Tax 1991 – 10% on all: Cars sold for more than $30,000 Boats sold for more than $100,000 Jewelry and furs above $10,000 Aircraft above $250,000 Guess what happened?

19. So, if you impose a tax on either the producer or a consumer of a product…. Will more or fewer products be sold? Will the price consumers pay be more or less than before?

Supply curve shifts upwards by the amount of the tax. New equilibrium = 5000 rooms supplied at $100 per room. Burden of tax shared by hotel and customers (hotel loses $20 per room, customers pay $20 more per room) Tax creates DEADWEIGHT LOSS

24. An Excise Tax Paid Mainly By Consumers D S $2.95 2.00 1.95 Price of gas (per pound) 0 Quantity of gasoline (pounds) Tax burden falls mainly on consumers Excise tax = $1 per gallon When the price elasticity of demand is low and the price elasticity of supply is high, the burden of an excise tax falls mainly on consumers.

25.

29. Deadweight Loss and Elasticities To minimize the efficiency costs of taxation, one should choose to tax only those goods for which demand or supply, or both, is relatively inelastic. For such goods, a tax has little effect on behavior because behavior is relatively unresponsive to changes in the price.
