Tax Tips for Petroleum Engineer Earnings
At this income level, you're in the 24% federal bracket and have access to more sophisticated tax reduction strategies:
Backdoor Roth IRA: If your income exceeds direct Roth contribution limits, use the backdoor strategy—contribute to a traditional IRA then convert to Roth. This provides tax-free growth and withdrawals in retirement.
Mega Backdoor Roth: If your employer's 401(k) allows after-tax contributions and in-plan conversions, you can contribute up to $69,000 total (employee + employer) and convert the after-tax portion to Roth—a powerful wealth-building strategy.
SALT Cap Strategy: The $10,000 state and local tax deduction cap may limit your itemized deductions. If you're in a high-tax state, consider strategies like bunching charitable deductions in alternate years using a donor-advised fund.
Tax-Loss Harvesting: If you have taxable investment accounts, systematically harvesting losses to offset gains can save significant taxes while maintaining your investment strategy through substantially different replacement positions.
401(k) + HSA Maximum: Prioritize maxing both accounts—$23,500 (401k) + $4,300 (HSA) = $27,800 in pre-tax deductions, saving you $6,672 in federal taxes at the 24% bracket.
