How much capital loss can you deduct?
You can deduct up to $3,000 in capital losses against your ordinary income each year ($1,500 if married filing separately). Any losses exceeding this limit carry forward to future tax years indefinitely.
According to IRS Publication 550, capital losses first offset capital gains of the same type (short-term losses offset short-term gains), then offset the opposite type, and finally up to $3,000 offsets ordinary income.
Example: Capital loss deduction calculation
Let's say you're married filing jointly with these 2026 transactions:
Step-by-step calculation:
1. Net short-term: $8,000 loss
2. Net long-term: $2,000 gain - $4,000 loss = $2,000 loss
3. Overall net loss: $8,000 + $2,000 = $10,000 loss
4. Current year deduction: $3,000 against ordinary income
5. Carryforward to 2027: $7,000 remaining loss

Advanced strategy: Loss harvesting timing

You have $12,000 in unrealized losses and $5,000 in unrealized gains:

Important limitations:
What you should do
1. Track all investment transactions - Use Form 8949 and Schedule D
2. Maintain carryforward records - The IRS doesn't track this for you
3. Consider tax-loss harvesting - Systematically realize losses to offset gains
4. Time your sales strategically - Maximize the $3,000 annual deduction
5. Review before year-end - December is prime time for loss harvesting

Special rules for trader tax status
If you qualify for trader tax status, your capital loss limitations work differently than regular investors.
Mark-to-market election (Section 475)
Traders can elect mark-to-market accounting, which treats all trading gains and losses as ordinary income/loss rather than capital:
Example: Trader vs. investor treatment
Say you have a $25,000 trading loss:
Business vs. investment activity
The key factors for trader status include:
What you should do
1. Document trading activity - Maintain detailed records of time spent and transactions
2. Consider Section 475 election - Must be made by the return due date (including extensions)
3. Evaluate the trade-offs - Ordinary loss treatment vs. capital gains rates
Key takeaway: Traders with Section 475 elections can deduct unlimited trading losses as ordinary losses, but must treat all gains as ordinary income too.
Key Takeaway: Traders with Section 475 elections can deduct unlimited trading losses as ordinary losses, but must treat all gains as ordinary income too.

Best for retirees managing substantial capital loss carryforwards
Managing capital loss carryforwards in retirement
Retirees often accumulate large capital loss carryforwards that can take decades to utilize at $3,000 per year.
Example: Retiree capital loss strategy
A retiree has $45,000 in capital loss carryforwards and needs income:
Strategic gain realization
Roth conversion coordination
Realize capital gains in the same year as Roth IRA conversions:
Asset location benefits
Estate planning considerations
Capital loss carryforwards do not transfer to beneficiaries - they disappear at death. This makes accelerated utilization important for older investors.
Key takeaway: Retirees should actively realize capital gains to accelerate the use of loss carryforwards, especially since these losses disappear at death.
