Tax Optimization for Data Scientists

Maximize 401k

💼 401k Contributions (2026 Limits)

Contribute up to $23,500 to your traditional 401k ($31,000 if age 50+). This reduces your federal taxable income dollar-for-dollar. A data scientist in the 24% bracket saves $5,640 in federal taxes by maxing out their 401k. Washington has no state tax, so you don't get additional state savings (unlike California where you'd save another ~$2,400).

Mega Backdoor Roth

🚀 Mega Backdoor Roth (Amazon, Microsoft, etc.)

Many Washington tech companies (Amazon, Microsoft, Google) allow after-tax 401k contributions up to $70,000 total (2026 limit including employer match). Convert after-tax contributions to Roth 401k or Roth IRA. This allows $30,000+ additional Roth contributions annually, providing massive tax-free growth potential for high earners.

RSU Strategy

💰 Stock Compensation Tax Planning

RSUs are taxed as ordinary income upon vest. Consider: (1) Withholding adjustment — ensure enough federal withholding to avoid underpayment penalties; (2) Timing — if you expect lower income next year, negotiate delayed vesting; (3) 83(b) election — for stock options (not RSUs), consider early exercise to start capital gains clock.

Backdoor Roth

📈 Backdoor Roth IRA Strategy

High-earning data scientists (income >$161,000 single / $240,000 married) can't contribute directly to Roth IRA. Use the Backdoor Roth: contribute $7,000 to traditional IRA (non-deductible), then immediately convert to Roth. No tax on conversion since basis = contribution. Future growth is tax-free.
