You signed the contract. $340,000. You did the math in your head — that's roughly $28,000 a month, $13,000 every two weeks. After years of residency at $68,000, you're finally going to feel the difference.
Then the first paycheck hits your bank account. And it's… not $13,000. It's not even close.
Welcome to attending taxes. For a physician in California, the gap between what you earn and what you keep is one of the most jarring financial experiences of your career. Maybe you mentally prepared for it, maybe you didn't.
But this is how it works. Here's exactly where every dollar goes.
The Paycheck, Dissected
Let's take a single physician earning $340,000 as a W-2 employee in California, paid biweekly (26 pay periods). No pre-tax retirement contributions yet — just the raw paycheck before any optimization.
That's 41.4% of your gross pay that never hits your bank account. On an annual basis, you're earning $340,000 and taking home roughly $199,000 to $207,000 — depending on your W-4 elections and whether Social Security withholding stops mid-year after you hit the $184,500 wage base.
In residency, your effective tax rate was probably around 22-25%. Now it's north of 38%. The jump from a $68,000 salary to $340,000 didn't 5x your take-home. It roughly 3x'd it.
Where Every Dollar Actually Goes
Federal income tax is the largest bite at roughly $82,000 on $340,000 of taxable income after the standard deduction. Your marginal rate — the rate on your last dollar earned — is 32%. But your effective rate (total tax ÷ gross income) is closer to 24%, because the progressive bracket system taxes your first dollars at 10% and 12%.
California income tax adds another $28,000 or so. California's top marginal rate is 9.3% above $68,350 (single) and 10.3% above $349,137, with an additional 1% Mental Health Services Tax surcharge above $1 million. There is no preferential rate for any type of income — wages, capital gains, retirement distributions — California taxes it all the same.
FICA taxes (Social Security + Medicare) contribute roughly $17,600. Social Security is capped at 6.2% on the first $184,500 of earnings ($11,439 maximum), but Medicare has no cap — you pay 1.45% on all earnings, plus an additional 0.9% on earnings above $200,000 (single). That Additional Medicare Tax is the one that surprises people: it's 0.9% with no employer match and no cap.
California SDI (State Disability Insurance) adds approximately $3,700 at a rate of 1.1% on wages up to $340,652 in 2026.
The Marginal Rate Is What Matters
At $340,000 in California, your combined marginal rate on the next dollar you earn is approximately 43.1%: 32% federal + 9.3% California + 1.45% Medicare + 0.9% Additional Medicare. That's the rate that determines how much every raise, bonus, or side income actually puts in your pocket — and it's the rate that makes tax planning so valuable at your income level.
The distinction between marginal and effective rates is critical, because it drives every tax planning decision you'll make. Your effective rate (the blended average across all brackets) tells you what you paid. Your marginal rate tells you what you'll save for every dollar you shelter from taxes.
Every dollar you contribute to a pre-tax 401(k) or 403(b) saves you $0.43 in combined taxes. That's not a metaphor. That's the literal math. A $24,500 pre-tax retirement contribution at a 43% marginal rate saves you $10,535 in taxes this year. That's money you would have sent to the IRS and Sacramento — instead, it's compounding in your retirement account.
What You Can Actually Do About It
You can't change the tax brackets. But you can change how much of your income is subject to them. Here are the strategies that have the largest impact for a physician at this income level, ranked by annual tax savings potential:
401(k) or 403(b): $24,500 pre-tax contribution reduces taxable income at a 43% marginal rate = $10,535 saved. Governmental 457(b) (if your hospital offers one): another $24,500 = another $10,535. These are separate buckets — you can contribute to both. Many physicians don't know the 457(b) exists, and those who do often don't realize it doesn't have an early withdrawal penalty.
We covered the full ordering in our post on the ideal investment order for high earners.
If you're enrolled in a high-deductible health plan, you can contribute $4,300 (individual) or $8,550 (family) to an HSA in 2026. Contributions are pre-tax, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. It's the only account in the tax code with a triple tax advantage. After age 65, HSA funds can be used for any purpose (taxed like a traditional IRA) — making it a stealth retirement account.
At $340,000, you can't contribute directly to a Roth IRA. But the backdoor strategy — contribute to a non-deductible traditional IRA, then convert to Roth — is available and legal. That's $7,000 per year into an account that will never be taxed again. Over 30 years at 7%, $7,000/year becomes approximately $660,000 in tax-free retirement income. If you're married, both spouses can do this — that's $14,000/year.
If you're charitably inclined, bunching two or three years of donations into a single tax year (through a donor-advised fund) allows you to itemize deductions in the bunching year and take the standard deduction in the off years. At a 43% marginal rate, a $30,000 charitable donation reduces your tax bill by $12,900. The standard deduction for 2026 is $15,700 (single) or $31,400 (MFJ) — so bunching only helps if your total itemized deductions exceed those thresholds.
If you have a taxable brokerage account, selling positions at a loss to offset gains reduces your capital gains tax. Up to $3,000 in net losses can offset ordinary income annually, with excess losses carried forward. At a combined federal + California rate of 33%+ on short-term gains and 28%+ on long-term gains, this is real money — and it's completely passive (for you) if your advisor handles it systematically.
The Optimized Paycheck vs. The Unoptimized Paycheck
| No Optimization | With Tax Strategies | |
|---|---|---|
| Gross income | $340,000 | $340,000 |
| Pre-tax retirement contributions | $0 | $49,000 (403b + 457b) |
| HSA contribution | $0 | $8,550 (family) |
| Taxable income | $324,300 | $266,750 |
| Federal income tax | ~$82,000 | ~$63,500 |
| California income tax | ~$28,000 | ~$22,500 |
| FICA (unchanged) | $17,600 | $17,600 |
| CA SDI (unchanged) | $3,700 | $3,700 |
| Total tax bill | ~$131,300 | ~$107,300 |
| Tax savings | — | ~$24,000 |
| Cash to retirement accounts | $0 | $57,550 (403b + 457b + HSA) |
The physician who maxes their pre-tax accounts doesn't take home $24,000 less in cash — they redirect that money from the government to their own retirement accounts, and the tax savings partially offsets the cash flow difference. In practice, the difference in take-home pay is closer to $33,000 ($57,550 contributed minus $24,000 in tax savings), which works out to about $1,270 per biweekly paycheck. A meaningful adjustment, not a dramatic sacrifice.
And that $57,550 per year, growing at 7% for 25 years? That's roughly $4.3 million in retirement savings — funded largely by money that would have otherwise gone to taxes.

The Bottom Line
Your first attending paycheck is going to be smaller than you expected. It's just the reality of being a newly-minted high earner in a high-tax state. Federal brackets, California's flat treatment of all income, FICA, the Additional Medicare Tax, and state disability insurance combine to take roughly 38% to 42% of your gross pay before you've bought groceries or made a loan payment.
The tax code gives high earners significant tools to reduce the bill. Pre-tax retirement accounts, HSAs, backdoor Roth strategies, charitable bunching, and tax-loss harvesting can collectively save you $20,000 to $30,000 per year — and that savings compounds alongside your investments for decades.
The physicians who end up with the largest retirement accounts are the ones who optimized the earliest. The first paycheck stings. The next 30 years of tax-smart planning is where the real money is made.
