Alert (Jan. 11, 2013): Tax Act's Impact On Stock Comp
This email alert summarizes the provisions in the American Taxpayer Relief Act of 2012 and other recent legislation that have an impact on stock compensation. With effect from January 1, 2013, the following changes in tax rates apply to income from stock option exercises, restricted stock and RSU vesting, ESPP purchases, sales of stock, and dividends. (See related FAQs at myStockOptions.com that show the taxes and withholding rates for various types of equity awards.)
- The top federal withholding rate on supplemental income rose to 39.6%. Supplemental income, such as stock compensation, is subject to one of two flat rates that are linked to income tax rates. For aggregate supplemental wage payments totaling up to $1 million during the year, the rate is 25% (the rate of the third income tax bracket). For aggregate supplemental wage payments that exceed the level of $1 million in a calendar year, the rate is now 39.6% (the new rate of the highest income tax bracket).
- The Social Security rate returned to 6.2% after a temporary cut to 4.2% in 2011 and 2012, as the new tax law did not extend the reduction in payroll tax. Social Security tax applies up to a certain amount of yearly income ($113,700 in 2013) and not to yearly income above that threshold.
- The capital gains tax rate that applies to the proceeds from a stock sale increased to 20% for single filers with yearly taxable income of more than $400,000 and for married joint filers with yearly taxable income of more than $450,000. (For taxpayers whose yearly taxable income is below these thresholds, the top rate of capital gains tax remains 15%.)
- Similarly, the tax rate on dividends grew to 20% for single filers whose yearly taxable income is over $400,000 and for married joint filers whose yearly taxable income is over $450,000. This applies to any qualified dividends received on company stock you own or on unvested restricted stock for which you have filed a Section 83(b) election.
- For people with incentive stock options, the income exemption amounts (commonly known as the "AMT patch") for calculating the alternative minimum tax in 2012 are $50,600 for single filers and $78,750 for married joint filers. Additionally, the new tax law indexed the annual AMT income exemption amounts permanently for inflation. The projected exemption amounts for 2013 are $51,900 and $80,750. The new tax legislation did not extend the refundable AMT credit that was available for the tax years 2007 through 2012.
- qualified small business stock issued between now and the end of 2013, 100% of the gains will be excludable from capital gains tax (0% rate) and omitted from the AMT calculation. The provision was made retroactive to September 27, 2010. The exclusion helps anyone buying stock in a small privately held company, including stock from an option exercise or restricted stock vesting.
- Separately from the American Taxpayer Relief Act, in 2012 the Affordable Care Act increased the Medicare tax rate on compensation income for high-income taxpayers from 1.45% to 2.35%, and a new 3.8% Medicare surtax now applies to investment income, such as capital gains from stock sales. Both of these tax changes became effective on January 1, 2013.
For high-income taxpayers, the new income thresholds for increased tax rates, the new Medicare taxes, and the return of exemption/itemized deduction phaseouts will make it more appealing to:
- defer income into the future with restricted stock units and performance share units that allow the deferral of share delivery (see a related FAQ)
- defer salary and bonus in nonqualified deferred compensation plans
- receive stock options, as options offer the ability to time the year for recognizing income, depending on when you exercise them
For people in the highest tax bracket, the tax advantages of ISOs over NQSOs have been slightly reduced, as the spread between the highest ordinary income rate and the capital gains rate (plus 3.8% Medicare surtax) is now 15.8% (39.6% – 23.8%). This is less than from the previous spread of 20% (35% – 15%). However, the bigger gap between the higher top ordinary income rate and the top AMT rate (still 28%), makes it less likely that individuals in the 39.6% bracket will trigger the AMT from an ISO exercise/hold.
