Married couples filing jointly who keep their taxable income below $98,900 in 2026 will owe zero federal tax on long-term capital gains realized that year. The IRS locked in that threshold through Rev. Proc. 2025-32, published after applying inflation adjustments required by the Internal Revenue Code. The new figures take effect for tax year 2026, with returns due in 2027, giving households months to plan around a zero-rate bracket that has quietly expanded again.
How the $98,900 zero-rate bracket changes 2026 planning
The zero-percent rate on long-term capital gains is not new, but the income ceiling that controls access to it shifts each year with inflation. For 2026, the IRS set the married-filing-jointly breakpoint at $98,900 of taxable income in its annual inflation tables, which list the updated brackets for multiple provisions. Taxable income, in this context, means gross income minus deductions, not total wages or portfolio value. That distinction matters because a couple earning well above the threshold in gross terms can still land below it after the standard deduction and other adjustments.
The practical question for investors and retirees is timing. One plausible hypothesis holds that households near the boundary will rush to sell appreciated assets in late 2025 to lock in whatever zero-rate ceiling applies for the current tax year, before the 2026 band takes effect. But that logic runs backward. Because the 2026 threshold is higher than the 2025 figure, couples actually gain more room to harvest gains at zero percent by waiting until January 2026 rather than selling in December 2025. Accelerating sales into 2025 would only make sense for taxpayers who expect their ordinary income to jump significantly in 2026, pushing them above the expanded ceiling.
Households also need to remember that the $98,900 figure is a cliff for the zero-rate band, not a hard cap on realizing gains. A couple can sell enough appreciated assets to push their taxable income well above that level; the portion of their long-term gains that falls within the band is taxed at 0%, while the excess is taxed at 15% or 20% depending on where total income lands. That creates opportunities to “fill up” the zero-rate bracket each year with carefully sized sales, especially for retirees who can flex their ordinary income by adjusting IRA withdrawals or delaying Social Security.
Statutory framework behind the zero-percent rate
Long-term capital gains and qualified dividends can be taxed at 0%, 15%, or 20%, depending on where a filer’s taxable income falls relative to statutory breakpoints. The IRS describes this tiered structure in its guidance on capital gains, which confirms that net long-term gains qualify for the zero-percent rate when taxable income stays within the lowest bracket. The statutory authority sits in 26 U.S. Code Section 1(h), which lays out the capital gains framework and ties the bracket thresholds to annual inflation indexing.
H.R. 1, which became Public Law 119-21, reshaped parts of the post-2025 tax regime. The IRS incorporated those legislative changes into its 2026 inflation adjustments, as noted in IR-2025-103, which links directly to Rev. Proc. 2025-32 for the full technical details. The result is a capital gains schedule that preserves the three-rate structure but nudges the breakpoints higher, including the $98,900 zero-rate ceiling for joint filers.
Coordinating deductions, income, and capital gains
Because the zero-percent band is based on taxable income, deductions play a central role in planning. A married couple that expects $110,000 of gross income in 2026 might still qualify for the zero-rate on some or all of their long-term gains after subtracting the standard deduction and any above-the-line adjustments. Itemized deductions such as mortgage interest or charitable gifts can widen the gap further, effectively creating more room to realize gains at 0%.
At the same time, taxpayers need to consider how other decisions interact with the bracket. Large traditional IRA withdrawals, Roth conversions, or bonuses can crowd out space in the zero-rate band by raising ordinary income. Conversely, strategically delaying such income into a later year-or spreading it over multiple years-can preserve more of the $98,900 ceiling for long-term gains and qualified dividends.
Reporting zero-rate gains correctly
Even when long-term gains fall entirely within the zero-percent bracket, they still must be reported. The IRS explains the mechanics of reporting sales, calculating net gains, and applying the appropriate rate on Schedule D instructions. Taxpayers typically report individual transactions on Form 8949 and then summarize totals on Schedule D, where the zero, 15%, and 20% rates are applied through a worksheet or tax computation.
For households near the $98,900 threshold, careful recordkeeping and use of tax software or professional advice can ensure that the zero-rate benefit is fully captured. Misclassifying short-term trades as long-term, overlooking basis adjustments, or failing to coordinate gains with other income can all erode the intended advantage of the expanded 2026 bracket. With the rules now set well in advance, couples have time to model different income and harvesting strategies before committing to major portfolio moves.
