TAX TALK: Basics of Incentive Stock Options

Hal Zemel, CPA, J.D., LL.M. 02.13.2017 | TAX TALK

Incentive stock options (“ISOs”) allow you to buy your employer’s stock in the future at a fixed exercise price. The exercise price must at least equal the stock’s fair market value on the date granted. If the stock appreciates above the exercise price, the ISOs will allow you to buy the stock at a price below the fair market value (“FMV”) on the exercise date. However, complex tax rules apply to this type of compensation.

Tax Treatment of ISOs

ISOs must comply with many rules (not discussed here), but receive tax-favored treatment:

GRANT DATE: On the date your employer grants your ISOs - You owe no tax.

EXERCISE DATE (purchase stock at exercise price) On the date you exercise the ISOs:

  • Regular Tax
    1. You owe no regular income tax. There may be other tax consequences if you leave your employment and exercise the ISO.
    2. Your basis in the stock will equal the exercise price that you pay.

  • Alternative Minimum Tax (“AMT”)
    1. You will have an AMT adjustment equal to the FMV of the stock on the date of exercise in excess of the exercise price of the ISOs.
    2. Depending on your tax situation, the AMT adjustment may cause you to pay AMT.
    3. You will add the AMT adjustment to your basis in the stock in order to calculate your AMT gain or loss when you sell the stock.
    4. Generally, you will receive an AMT credit carry-forward to offset future regular tax liability to alleviate potential double taxation.

  • DISPOSITION DATE (sell stock):
    1. Regular Tax
      1. If you sell the stock after holding the shares at least one year from the exercise date and two years from the grant date, you pay tax on the sale at your long-term capital gains rate.
      2. You will calculate the gain on the excess of the amount you receive for the stock sale over the basis in the stock (the exercise price paid).
      3. If the stock has gone down in value since the exercise, you will have a capital loss.
      4. You also may owe the 3.8% net investment income tax (NIIT).
      5. If you sell the stock before long-term capital gains treatment applies, a “disqualifying disposition” occurs and any gain is taxed as compensation at ordinary-income rates.
    2. AMT
      You will have a reduction in AMT income equal to the amount of the AMT adjustment you included when you exercised the ISOs.

Exercises and Stock Sales

So, if you were granted ISOs in 2016, there likely isn’t any impact on your 2016 income tax return. But, if in 2016 you exercised ISOs or you sold stock that you’d acquired via exercising ISOs, then it could affect your 2016 tax liability. It’s important to properly report the exercise or sale on your return to avoid potential interest and penalties for underpayment of tax.

If you receive ISOs in 2017 or already hold ISOs that you haven’t yet exercised, plan carefully when to exercise them. Waiting to exercise ISOs until just before the expiration date (when the stock value may be the highest, assuming the stock is appreciating) may make sense. But, exercising ISOs earlier can be advantageous in some situations.

Once you’ve exercised ISOs, the question is whether to immediately sell the shares received or to hold on to them long enough to garner long-term capital gains treatment. The latter strategy often is beneficial from a tax perspective, but there’s also market risk to consider. For example, it may be better to sell the stock in a disqualifying disposition and pay the higher ordinary-income rate if it would avoid AMT on potentially disappearing appreciation.

The timing of the sale of stock acquired via an exercise could also positively or negatively affect your liability for higher ordinary-income tax rates, the top long-term capital gains rate and the NIIT.

Planning Ahead

Keep in mind that the NIIT is part of the Affordable Care Act (ACA), and lawmakers in Washington are starting to take steps to repeal or replace the ACA. So, the NIIT may not be a factor in the future. In addition, tax law changes are expected later this year that might include elimination of the AMT and could reduce ordinary and long-term capital gains rates for some taxpayers. When changes might go into effect and exactly what they’ll be is still uncertain.

If you’ve received ISOs, contact us. We can help you ensure you’re reporting everything properly on your 2016 return and evaluate the risks and crunch the numbers to determine the best strategy for you going forward. You can reach me at HZemel@BerdonLLP.com  or contact your Berdon advisor.
