Data scientists often receive significant equity compensation, especially at tech companies. RSU vesting creates lumpy income that can push you into higher brackets in certain years. Conference speaking fees and consulting income on the side are common in this field and must be reported as self-employment income.

Consider tax-loss harvesting on personal investments to offset gains from equity compensation.
