Advanced Tax Planning for $150k+ Earners
Standard tax advice — maximize 401(k), contribute to HSA — applies at every income level. But high earners have additional strategies worth tens of thousands annually.
Strategy 1: Mega Backdoor Roth
The mega backdoor Roth lets you contribute after-tax dollars to your 401(k) — beyond the $23,500 employee limit — up to the total 401(k) limit ($70,000 in 2026 including employer contributions). Then convert those after-tax dollars to Roth.
How it works:
- Confirm your plan allows after-tax contributions and in-plan Roth conversions
- Contribute after-tax dollars up to the plan limit (typically $40,000–$46,500 in after-tax space)
- Convert immediately to Roth (avoiding any growth that would be taxed)
Strategy 2: Tax-Loss Harvesting
If you have taxable investment accounts, tax-loss harvesting sells investments at a loss to offset capital gains:
- Offset short-term capital gains (taxed as ordinary income at up to 37%)
- Offset long-term capital gains (taxed at 0–23.8%)
- Deduct up to $3,000 in losses against ordinary income
Strategy 3: Qualified Small Business Stock (QSBS)
If you hold stock in a qualified startup (Section 1202), gains up to $10 million can be completely tax-free. For employees at early-stage companies, this is potentially the single largest tax benefit available.
Requirements: C-corp, acquired at original issue, held 5+ years, company had under $50M in assets at issuance.
Strategy 4: Deferred Compensation Plans (NQDC)
Many large employers offer non-qualified deferred compensation plans allowing high earners to defer additional salary or bonuses beyond 401(k) limits. This defers income tax until a future date (ideally lower-income years).
Risk: This is an unsecured liability of your employer. If the company goes bankrupt, you may lose the deferred amount.
Strategy 5: Donor-Advised Funds (DAFs)
If you give to charity, a Donor-Advised Fund lets you:
- Deduct the full amount in the contribution year (even if grants go out over years)
- Donate appreciated securities (avoid capital gains tax)
- "Bunch" multiple years of giving into one year to exceed the standard deduction
Strategy 6: Relocation to a No-Tax State
At $200,000 in California:
- California state income tax: ~$15,000–$18,000/year
- Moving to Texas: $0 in state income tax
- Annual savings: $15,000–$18,000
