Yes, for individual taxpayers in the U.S., capital losses can be carried forward indefinitely until they are completely used up. There is no expiration date for these losses, though they cannot be carried back to previous years. The losses must be used to offset capital gains first, with up to $ 3 , 000 $ 3 , 0 0 0 ( $ 1 , 500 $ 1 , 5 0 0 married filing separately) of excess loss allowed to reduce ordinary income annually.
You don't lose any unused balance of your capital loss because the Internal Revenue Code (IRC) includes a provision that allows you to carry any remaining balance forward for an unlimited number of years until it's depleted. This concept is referred to in tax lingo as a capital loss carryover.
You can apply your net capital loss against a taxable capital gain from another year to reduce it – either carry it back to any of the past 3 years, or carry it forward to use in a future year. To carryback a loss (apply it to a previous year), complete form T1A: Request for loss carryback.
Any excess loss can be carried forward indefinitely. Carried forward losses may be offset against gains in future years. Unlike current year losses it's only necessary to offset sufficient carried forward losses against gains in excess of the annual exemption.
Report on the Correct IRS Forms
Capital gains and losses—including carryovers—are reported on Schedule D (Form 1040) and Form 8949, which provide detailed calculations for each asset sold.
The IRS 7-year rule primarily applies to keeping records for claiming a deduction for bad debts or losses from worthless securities, allowing a longer period to file for a credit or refund, but it's not a universal audit limit; it's often a recommended safe buffer for general record-keeping, with the standard IRS audit period usually being 3 years, extending to 6 years for substantial income omission (over 25%) or foreign income issues, and indefinitely for fraud.
The "6-year rule" for Capital Gains Tax (CGT) in Australia allows you to treat a former main residence as tax-exempt for up to six years after you move out, even if you rent it out, enabling you to avoid CGT on any growth during that period. You qualify by moving out, choosing to treat it as your main home for tax, and can reset the rule by moving back in. If you rent it out for longer than six years, only the portion of the gain after the six-year mark becomes taxable.
Short-term capital loss can be adjusted against long-term capital gains as well as short-term capital gains. Such loss can be carried forward for eight years immediately succeeding the year in which the loss is incurred.
Capital losses that exceed capital gains in a year may be used to offset ordinary taxable income up to $3,000 ($1,500 for MFS) in any one tax year. Net capital losses in excess of $3,000 ($1,500) can be carried forward indefinitely until the amount is used up.
Losses on your investments are first used to offset capital gains of the same type. So, short-term losses are first deducted against short-term gains, and long-term losses are deducted against long-term gains. Net losses of either type can then be deducted against the other kind of gain.
Capital Losses
A capital loss can be offset against capital gains of the same tax year, but cannot be carried back against gains of earlier years. If you have an unused capital loss, this can be carried forward indefinitely against gains of future years.
The "36-month rule" for capital gains tax (CGT) primarily refers to the UK's Principal Private Residence (PPR) Relief, where the final 36 months (or 9 months for most) of a property's ownership period are tax-exempt, even if not lived in, provided it was a main home at some point. In the US, the relevant rule for home sales is the "2-out-of-5-year rule" for the Section 121 exclusion, allowing up to $250k/$500k profit tax-free if owned and used as a main home for 2 of the 5 years before sale, with exceptions for unforeseen circumstances.
The 20% rule for capital gains refers to the highest federal tax rate for long-term capital gains, applying to higher income brackets when you sell investments (stocks, real estate) held for over a year, with lower rates of 0% and 15% for lower incomes, and even higher rates for special assets like collectibles. This rate kicks in for single filers earning over approximately $492,300 (2024) or $533,401 (2025), and higher for joint filers, making holding assets over a year a key tax strategy.
Yes, tax-loss harvesting (TLH) is often worth it for investors with taxable accounts, especially those in higher tax brackets or with significant capital gains, as it offsets gains and reduces ordinary income (up to $3,000/year) by selling underperforming assets, then reinvesting in similar ones to avoid the wash-sale rule, enhancing after-tax returns. However, it adds complexity, requires market monitoring, and offers limited benefit if you have few gains or are in a low bracket, making professional guidance important for personalized value, note Vanguard, Creative Planning, and White Coat Investor.
Yes, for the primary residence capital gains exclusion, you generally need to have owned and lived in the home for at least 2 of the last 5 years before the sale, but these two years don't have to be consecutive; however, you can't claim the exclusion if you've excluded gain on another home in the prior two years, with exceptions for unforeseen circumstances like job changes or health issues. For other investments, holding an asset for more than one year qualifies for lower long-term capital gains tax rates, but selling before two years means short-term gains taxed at your higher ordinary income rate.
Because you can carry capital losses forward indefinitely, you can apply losses from infinitely far back up to your current return. To carry losses forward, check your CRA My Account to obtain the current balance of your unclaimed losses.
—Save as otherwise provided in this Act, where the net result for any assessment year in respect of any source falling under any head of income is a loss, the assessee shall be entitled to have the amount of such loss set off against his income from any other source under the same head.
On a $100,000 capital gain, you'll likely pay 15% for long-term gains, resulting in about $15,000 in federal tax (plus potential state tax), but it could be 0% or 20% depending on your total taxable income and filing status, while short-term gains are taxed as ordinary income (potentially 22-24%).
To qualify for 0% capital gains tax, you must have long-term capital gains (assets held over a year) and your taxable income (after deductions) must fall below specific IRS thresholds, which change annually but are roughly <$48,350 for single filers and <$96,700 for married filing jointly for the 2025 tax year, allowing for higher total income when combined with deductions like the standard deduction. The key is keeping your adjusted gross income (AGI) low enough so that after subtracting deductions, your taxable income remains within these limits.
What happens if your losses exceed your gains? The IRS will let you deduct up to $3,000 of capital losses (or up to $1,500 if you and your spouse are filing separate tax returns). If you have any leftover losses, you can carry the amount forward and claim it on a future tax return.
