Investors and high earners filing as single taxpayers will keep the 15 percent rate on long-term capital gains until their taxable income crosses $545,500 in 2026, according to newly published IRS figures. Above that line, the rate jumps to 20 percent. The threshold, adjusted upward for inflation, means some households that would have faced the top rate under 2025 numbers will stay in the lower bracket even if their wages tick higher.
How the $545,500 Threshold Reshapes 2026 Tax Planning
The federal tax code taxes long-term capital gains and qualified dividends at three rates: 0 percent, 15 percent, and 20 percent. Which rate applies depends entirely on a filer’s taxable income. For single filers in 2026, the 15 percent rate holds until income reaches $545,500, as published in Revenue Procedure 2025-32 within Internal Revenue Bulletin 2025-45. Once taxable income exceeds that amount, the 20 percent rate kicks in on gains above the cutoff.
The practical effect for households earning between $400,000 and $600,000 is straightforward. Because the threshold rises each year with inflation, a filer whose income grew modestly from 2025 to 2026 could find that gains previously exposed to the top rate now fall entirely within the 15 percent bracket. Wage growth alone does not automatically push more filers into the 20 percent tier when the threshold climbs faster than most salaries. That dynamic matters most for taxpayers near the boundary who are deciding whether to realize gains before or after the calendar turns.
The legal framework behind these annual adjustments sits in Section 1(h) of the Internal Revenue Code, which establishes the 0, 15, and 20 percent structure for net capital gains. A separate provision, Section 1(j)(5), supplies the inflation-adjustment formula the IRS uses each fall to recalculate the dollar cutoffs. Together, those statutes have governed capital gains brackets since the rate structure was last overhauled more than a decade ago.
What Revenue Procedure 2025-32 Confirms for Single Filers
The IRS announced the 2026 inflation adjustments through News Release IR-2025-103, which directed taxpayers to Revenue Procedure 2025-32 for the detailed tables. That procedure lists the “maximum 15% rate amount” of $545,500 for the filing status labeled “All Other Individuals,” the category that covers single filers. The 20 percent rate applies above that figure, a point the IRS restates in its own plain-language guidance on capital gains and losses.
A Congressional Research Service report on the federal tax system confirms that only higher-income households face the top long-term capital gains rate. The three-rate structure concentrates the 20 percent burden on a relatively narrow slice of filers, while most investors with more modest incomes see their gains taxed at 15 percent or even 0 percent. The new $545,500 threshold continues that pattern by keeping the 20 percent bracket reserved for those with substantial taxable income.
For single taxpayers who hover just below or above the new cutoff, the updated figure has immediate implications for year-end strategy. Investors considering whether to sell appreciated stock, exercise stock options, or close out concentrated positions may find that deferring a large gain into 2026 keeps more of it in the 15 percent band if their projected income remains under the threshold. Conversely, those expecting a one-time spike in earnings-such as a business sale or large bonus-might accelerate some gains into a year when their income is lower to avoid tipping more of their portfolio into the 20 percent tier.
The interaction between wages, deductions, and investment income also becomes more important as the threshold rises. Because the capital gains brackets are keyed to taxable income, not gross income, steps that reduce adjusted gross income or increase itemized deductions can indirectly preserve access to the 15 percent rate. Retirement plan contributions, charitable gifts, or timing of deductible expenses may slightly lower taxable income and keep a filer from crossing the $545,500 line when gains are realized.
Tax professionals caution, however, that the capital gains rates do not operate in isolation. The 3.8 percent net investment income tax still applies above its own income thresholds, and state taxes can add another layer of cost on top of the federal 15 or 20 percent rates. In addition, the long-term rate structure applies only to assets held more than one year; short-term gains are taxed at ordinary income rates, which for high earners can exceed the top long-term rate by a wide margin.
Even with those caveats, the higher 2026 cutoff provides a modest tailwind for upper-middle-income investors. Households that might have expected to face the top rate on at least a portion of their gains may discover that the inflation adjustment has effectively expanded the 15 percent bracket enough to keep their realized gains out of the 20 percent range. For planners modeling multi-year liquidation of large positions, the new threshold offers slightly more room each year to harvest gains at the middle rate.
Ultimately, the $545,500 benchmark underscores how inflation indexing shapes the real-world burden of capital gains taxes. As long as statutory rates remain unchanged and thresholds continue to rise, more gains for single filers will be taxed at 15 percent rather than 20 percent, particularly for those whose incomes grow more slowly than the IRS inflation factors. For investors on the cusp of the top bracket, incorporating the updated 2026 figures into their planning can help align portfolio moves with the most favorable available rate.
