Capital Loss Carryforward Rules 2026: The $3,000 Limit

Updated for tax year 2026 · 6 min read

Sold RSU shares at a loss? Sitting on losses from a rough year in the market? The tax code doesn't let losses go to waste — but it rations how fast you can use them. Here is exactly how capital loss carryforwards work in 2026, in what order they apply, and how they interact with equity compensation sales.

The three-step ordering

Every year, your capital losses are applied in a strict sequence:

Offset capital gains dollar-for-dollar. Losses first cancel out gains of the same type (short-term losses against short-term gains, long-term against long-term), then any remainder nets against the other type. $40,000 of losses and $40,000 of gains = $0 net, regardless of type.
Deduct up to $3,000 against ordinary income. If losses still exceed gains, you can deduct up to $3,000 of the net loss against wages and other ordinary income ($1,500 if married filing separately).
Carry the rest forward indefinitely. Whatever remains carries to next year, where the same three steps repeat. There is no expiration and no limit on the number of years.

Worked example: the $50,000 loss

Jordan carries a $50,000 capital loss into 2026 This year Jordan realizes $30,000 of capital gains from selling RSU shares.

Step 1 — gains: $30,000 of gains wiped out dollar-for-dollar. Remaining loss: $20,000.
Step 2 — ordinary income: $3,000 deducted against salary.
Step 3 — carryforward: $17,000 carries to 2027.

At $3,000 per year with no future gains, the remaining $20,000 takes about 7 years to absorb — which is why step 1 matters so much: gains are where big carryforwards actually get used.

How carryforwards interact with RSU and ESPP sales

This is where equity compensation meets loss harvesting. Gains from selling vested RSU shares or ESPP shares are capital gains — which means an existing carryforward wipes them out dollar-for-dollar before the $3,000 trickle even starts. If you hold a large carryforward:

Selling appreciated RSU shares can be effectively tax-free at the federal level, up to the carryforward amount.
Tax-gain harvesting — deliberately selling winners to "use up" a carryforward and reset your cost basis higher — can make sense, since the gain costs you nothing in tax today and the higher basis reduces future tax.
Run the tradeoff in our sell-vs-hold calculator, which takes a carryforward input.

Note the boundary: the carryforward offsets capital gains freely, but only $3,000 per year of ordinary income — so it does almost nothing against salary, bonuses, or RSU vest income itself.

What the carryforward can't do

No carryback for individuals. You can't apply this year's losses to last year's return (unlike some business provisions). Forward only.
The $3,000 cap is real. A $300,000 net loss with no gains genuinely takes a century to deduct against salary alone. Plan around gains, not the annual drip.
Wash sales kill the loss. If you sell at a loss and buy a "substantially identical" security within 30 days before or after, the loss is disallowed (it gets added to the new shares' basis instead).
State rules mostly conform. Most states follow the federal treatment, including the annual limit, but a few have quirks — check your state's rules or model them in a state-aware calculator.

Putting the rules to work: tax-loss harvesting

The carryforward rules aren't just something that happens to you — they can be a deliberate strategy called tax-loss harvesting. The idea: in years when you have gains (say, $25,000 from selling RSU shares), you deliberately sell losing positions to realize ~$25,000 of losses, netting the gains to near zero. Because losses offset gains dollar-for-dollar with no annual cap, harvested losses are worth your full marginal capital-gains rate — far more valuable than the $3,000 yearly drip against salary.

A few ground rules for harvesting done right. First, respect the wash sale rule: don't repurchase the same (or "substantially identical") security within 30 days before or after the sale, or the loss is disallowed. Second, harvest before year-end — December is the classic window, but you can harvest any time gains appear. Third, think of an unused carryforward as a multi-year asset: a $60,000 carryforward lets you realize $60,000 of future gains tax-free whenever you choose, which pairs beautifully with rebalancing out of concentrated company stock. Just remember the ordering from above: harvesting only helps to the extent you have gains to absorb — beyond that, you're back to $3,000 a year.

Carryforward FAQ

Do capital losses expire?

No. Unused capital losses carry forward indefinitely at the federal level until fully used. Keep records — you'll need the running balance every year.

Can I use a carryforward against RSU vest income?

Only $3,000 per year ($1,500 MFS) against ordinary income like vest income. But the same carryforward offsets gains from selling those shares dollar-for-dollar without limit.

What happens to my carryforward if I die?

It dies with you — capital loss carryforwards generally can't be transferred to heirs or used on a final return beyond that year's limits. Another reason to use them against gains while you can.

Do I need to do anything special to claim it?

Report it on Schedule D and the Capital Loss Carryover Worksheet each year. Tax software usually tracks it automatically once entered; switching software is where people lose the thread.
