Investors got a rare piece of good news buried in the latest IRS inflation adjustments: the income thresholds for long-term capital gains taxes are creeping higher again for tax year 2026.
That means more of your investment profits could fall into the 0% bracket, or stay out of the top 20% rate, depending on where you land.
For 2026, the 0% long-term capital gains rate applies to taxable income up to $49,450 for single filers and $98,900 for married couples filing jointly.
The 15% rate stretches up to $545,500 for singles and $613,700 for joint filers.
Anything above those numbers gets hit with the 20% rate.
Those thresholds matter more than most people realize.
A married couple who sells a rental property or cashes out decades of stock gains could save thousands simply because the cutoff moved up.
The increases are modest — a few hundred to a few thousand dollars — but they compound across every asset you sell in a given year.
One detail that trips up even experienced investors: capital gains taxes are calculated on your total taxable income, not just the profit from the sale.
A big one-time gain can push you from the 0% bracket straight into 15% or even 20% territory, catching people off guard in April.
If you're sitting on a large unrealized gain, spreading sales across two calendar years can keep more of it in a lower bracket.
Retirees living mostly on Social Security and a small pension often qualify for the 0% rate entirely — a fact that surprises many who assume any investment profit gets taxed.
There's also the net investment income tax, a 3.8% surcharge that kicks in once modified adjusted gross income tops $200,000 for singles or $250,000 for couples.
That's separate from the capital gains brackets and frequently overlooked until the tax bill arrives.
Short-term gains — assets held a year or less — are taxed as ordinary income, which can mean rates as high as 37%.
That single rule is why financial planners keep repeating the same advice: hold longer than 12 months whenever you possibly can.
Worth noting for homeowners: the primary residence exclusion still lets singles shield $250,000 of profit and couples $500,000, provided you've lived in the home two of the last five years.
That's on top of whatever the capital gains brackets allow.
These numbers shift every year with inflation, and a five-minute check of where your income lands could change when you decide to sell — or how much you sell in one shot.
Most people never look until it's too late. **Our take:** The annual bracket adjustments aren't dramatic, but they're free money for anyone paying attention.
Final Thoughts
If you're planning a big sale in 2026, run the numbers before December, not after.
