The 2026 federal rate schedule tops out at 37 percent. A Virginia Beach physician with $560,000 of income is paying roughly 45 cents of federal tax on her next dollar anyway, and nothing in her return will say so.
The culprit is not a rate. It is a disappearing deduction.
Here is the mechanic. The One Big Beautiful Bill Act, Public Law 119-21, raised the cap on the state and local tax deduction from $10,000 to $40,000 for 2025, with a one percent step-up each year through 2029. For 2026 the cap is $40,400. But above a modified adjusted gross income of $505,000, that cap shrinks by 30 cents for every additional dollar of income — and it stops shrinking when it hits the old $10,000 floor.
Do the arithmetic and the band defines itself. There is $30,400 of cap to lose, at 30 cents per dollar, which takes $101,333 of income. The phasedown is complete at roughly $606,300.
What the Band Actually Costs
Inside that roughly $101,000 stretch, every extra dollar you earn destroys 30 cents of deduction. At a 35 percent marginal bracket, losing 30 cents of deduction costs about 10.5 cents of additional tax. Add that to the stated rate and your true federal marginal rate in the band runs somewhere around 45 to 47 percent, depending on where the dollar lands in the rate schedule.
Then it stops. At $610,000 of income the cap is already at its $10,000 floor, so the next dollar goes back to costing you the ordinary bracket rate. The surcharge is real, it is steep, and it is confined.
One detail that catches Hampton Roads two-income households: the $505,000 threshold is the same number for single filers and for married couples filing jointly. Two physicians in one household do not get two thresholds. They get one.
Priya's December Bonus
Priya is an anesthesiologist in Chesapeake. She and her husband expect about $585,000 of modified adjusted gross income for 2026, and her practice is deciding whether to pay a $45,000 productivity bonus in December or in January.
Paid in December, roughly the first $21,000 of that bonus lands inside the phasedown band, where it carries the extra 10-plus cents per dollar. Paid in January, the same bonus lands in a year where her income starts from zero and the first $505,000 of it sits under the threshold entirely.
Nothing about the bonus changed. Only the calendar did. That is what makes this band worth knowing about in October rather than in April.
The Band Is Crowded
The SALT phasedown does not run alone. Two other things are happening in the same neighborhood of income.
The 3.8 percent net investment income tax is already fully engaged well below $505,000, so any investment income you realize in the band carries that on top.
And the income you report in 2026 sets your Medicare premium in 2028. The income-related adjustment looks back two years. For context, the standard Part B premium is $202.90 per month in 2026; the surcharge tiers sit well above that. A one-time bonus or a large Roth conversion in the band can raise a premium two years later that has nothing to do with that year's income.
Meanwhile the new half-percent floor on charitable deductions, which took effect for 2026, means the charitable gift you might use to manage income in this band is itself worth slightly less than it used to be.
Five Levers Before December 31
- Move the income. Defer a bonus, delay a December billing cycle, or push a partnership distribution into January if it lands inside the band.
- Size the Roth conversion to the threshold, not the bracket. The old instinct was to fill up the 24 or 32 percent bracket. In this range the better instruction is often to stop at $505,000 and convert the rest next year.
- Time gains and harvest losses deliberately. Realized capital gains count toward modified adjusted gross income. A loss harvest that pulls you under $505,000 is worth more than its face value.
- Fund the pre-tax plans fully, including a cash balance plan if your practice or business has one. These reduce the income that drives the phasedown.
- Look hard at Virginia's elective pass-through entity tax. If you own an interest in a partnership or S corporation, Virginia's PTET lets the entity pay the state tax and deduct it before income reaches you. That state tax never touches your Schedule A, so it is never subject to the cap or the phasedown. Virginia has made the election permanent, and the One Big Beautiful Bill Act left these state regimes untouched.
Should I Just Stop Itemizing?
For some households in this band, yes, and it is worth running rather than assuming.
The 2026 standard deduction is $32,200 for married couples filing jointly and $16,100 for single filers. If your SALT deduction has been phased down toward $10,000 and your mortgage is modest or paid off, itemizing may no longer beat the standard deduction at all. In that case the SALT phasedown costs you nothing, because you were not using the deduction anyway.
That is not a consolation prize. It is a planning fact. It means the levers above matter enormously for one household and not at all for the one next door, and the only way to know which one you are is to run your own numbers before year end rather than in April.
Why This Does Not Belong to Your CPA Alone
The phasedown is a tax rule. Every lever that addresses it is something else.
Deferring a bonus is a compensation decision. Sizing a Roth conversion is a retirement income decision. Harvesting losses is a portfolio decision. Electing Virginia's pass-through entity tax is an entity decision that touches your operating agreement. When those conversations happen in four different offices between January and April, the year is already over.
