Case study: a SAR payout at a private company

What does a stock appreciation right actually feel like when it finally pays? Like a giant bonus with a tax bill that does not match the cash you kept. Here is a composite of an engineer I will call Daniel, who held SARs at a private company for four years and learned the hard way that the word “stock” in the name buys you nothing at tax time.

The setup

Daniel joined a late-stage private company early enough to get a grant of stock appreciation rights on 20,000 units, with a base price of $8 a share. No strike to pay, no shares to buy. The deal was simple: whenever the company created a liquidity event, he would collect the rise in share price above his $8 base, in cash.

He thought of it as equity. It tracked the stock, it vested like the stock, his offer letter talked about it like the stock. So in his head, he was building a position that would someday get the long-term capital gains rate. That assumption was the expensive part.

The tender offer

Four years in, the company ran a tender offer, a private liquidity event where an outside buyer purchases shares from employees at a set price. The price came in at $30 a share. Daniel’s SARs were finally worth something real.

The math on the payout was clean. The $30 sale price minus his $8 base, times 20,000 units, came to $440,000 in cash. After years of paper value, a near-half-million-dollar payout hit his account.

The tax surprise

Daniel assumed the $440,000 would be taxed as a long-term capital gain. He had held the grant for four years, well past any one-year mark he had heard about. He was wrong, and not by a little.

The entire $440,000 was ordinary income, taxed at the same rate as his salary, plus payroll taxes. There was no holding period to clear, because he never owned an asset whose clock could start. A SAR puts nothing at risk and gives you nothing to own, so the appreciation is wages, no matter how many years go by.

Then came the second hit. The company withheld at the flat federal supplemental rate of 22% for 2026 2026, which on $440,000 is $96,800. Daniel’s real marginal rate, federal plus his state, was far above 22 percent, so the withholding came in light by a wide margin. The rest was his to cover at tax time.

What he should have done

The one real lever a SAR gives you is timing, and Daniel did not use it. He could not control the tender offer, but he could have planned for the bill the moment the offer was announced. Three moves would have saved him the April scramble.

He should have sized the true tax against the flat withholding the week the price was set, then parked the difference in cash instead of spending against the full payout. He should have made a quarterly estimated payment to cover the gap and dodge the penalty. And going in, he should have valued the SAR as deferred wages, not as stock, so the ordinary-income result was no surprise at all. The mechanics of that gap are the same one RSU holders hit at vesting.

What this means for you

If you hold SARs, read the payout as a wage event before it ever arrives, because that is what the code calls it. The capital gains rate never comes, the flat 22 percent withholding almost always falls short, and the only thing you control is when the income lands. Plan the tax the day the price is set, not the day the return is due. If a liquidity event is coming and the numbers are large, a quick fit check on the timing pays for itself many times over.
