What to know at this income level
Between $130,000 and $200,000 you cross into the 24% bracket at $103,350 taxable income (single). The marriage penalty or bonus becomes significant at this level — filing jointly can shift your brackets materially. You are approaching the Social Security wage base ($176,100 in 2025), meaning your SS tax stops accruing above that amount. Roth IRA direct contributions phase out between $150,000 and $165,000 (single), pushing higher earners toward the backdoor Roth strategy.
24% bracket strategy
At the 24% bracket, pre-tax 401(k) contributions save 24 cents per dollar — significantly more than at 22%. Maxing out the $23,500 limit saves $5,640 in federal tax. If you are over 50, the catch-up contribution adds another $7,500. Use calculator →
Roth IRA income phase-out
Direct Roth IRA contributions phase out between $150,000 and $165,000 MAGI for single filers in 2025. Above $165,000, use the backdoor Roth strategy — contribute to a Traditional IRA and convert to Roth. There is no income limit on conversions. Use calculator →
Social Security wage base
Social Security tax (6.2%) stops at $176,100 in 2025. If you earn $180,000, you effectively get a "raise" in your final paychecks of the year when SS withholding stops. Medicare (1.45%) has no cap and continues on all earnings. Use calculator →
Marriage tax implications
At this income, marriage significantly affects taxes. If both spouses earn similar amounts, you may face a marriage penalty (higher combined tax). If one spouse earns much more, you likely get a marriage bonus. Use our marriage calculator to model the difference. Use calculator →
Typical roles at this level: Senior engineers and developers, managers and directors, physicians in training, experienced lawyers, airline pilots, senior federal employees (GS-14/15), and established small business owners.
Frequently asked questions
How are RSUs (Restricted Stock Units) taxed?
RSUs are taxed as ordinary income when they vest, based on the fair market value at vesting. Your employer withholds federal and state income tax plus FICA. If you hold the shares after vesting and sell later at a profit, the gain is taxed as a capital gain (short-term if held under 1 year, long-term if over 1 year).
Do remote software engineers owe taxes in multiple states?
Generally, you owe income tax to the state where you physically perform work. If you work remotely from one state for a company in another, you typically only owe tax in your state of residence. However, some states have convenience-of-the-employer rules that could create dual-state obligations.
Can software engineers deduct a home office?
Only if self-employed or a 1099 contractor. W-2 employees cannot deduct home office expenses under current federal tax law, regardless of whether their employer requires remote work.
What is the backdoor Roth IRA and do I need it?
The backdoor Roth is a two-step process: (1) contribute to a Traditional IRA (no income limit), then (2) convert it to a Roth IRA. It is used by high earners who exceed the Roth IRA income limit ($165,000 single in 2025). The strategy works best if you have no existing pre-tax IRA balances — otherwise the pro-rata rule can create tax complications.
