Frequently Asked Questions

Why is my bonus taxed so heavily?

Bonuses aren't taxed at a higher rate, but they may be withheld at a higher rate (22% flat federal). When you file taxes, the actual tax is based on your total income. You may get excess withholding back as a refund.

What is the flat rate method for bonuses?

The IRS allows employers to withhold a flat 22% federal tax on bonus payments up to $1 million (37% above $1 million). This is simpler but may over-withhold for lower earners.

What are employee stock options?

Stock options give employees the right to buy company shares at a fixed price (strike price). If the share price rises above the strike price, the difference is your profit. They typically vest over 4 years.

What is the difference between ISOs and NSOs?

ISOs (Incentive Stock Options) have favorable tax treatment — gains may be taxed as long-term capital gains. NSOs (Non-Qualified Stock Options) are taxed as ordinary income upon exercise.
