Tax carryovers are important provisions in the U.S. tax code that help taxpayers preserve and maximize tax benefits that can’t be fully used in a single year. Instead of losing deductibles, credits, or losses that exceed the yearly limits, taxpayers can carry them forward — and in some cases backward — to other tax years.
Background and History
Tax carryovers have been part of U.S. tax law for decades. They serve to prevent taxpayers from losing value on deductions or credits simply because their income or tax liability isn’t sufficient to fully utilize these benefits in one year. The concept helps promote fairness by allowing these tax advantages to be applied over multiple years. Common areas with carryover rules include capital losses, charitable contributions, net operating losses (NOLs) for businesses, and certain tax credits.
How Tax Carryovers Work
Here’s a practical example with capital losses: if you have a $10,000 capital loss from selling investments, IRS rules allow you to deduct only $3,000 of that loss against ordinary income each year. The remaining $7,000 doesn’t disappear; instead, you carry over that amount to the next tax year(s) until it is fully deducted. This carryover reduces your taxable income and potentially lowers your tax bill over multiple years.
Carryovers also apply to:
- Charitable contributions above AGI limits, which can be carried over up to five years
- Net operating losses (NOLs) for businesses, which can offset income by carrying losses backward 2 years or forward up to 20 years under current law
- Tax credits with limits or income phase-outs, such as certain energy or child tax credits
- Alternative Minimum Tax (AMT) credits that can be applied over several years
Each type of carryover has specific IRS rules regarding how long it can be carried forward or backward and how much can be applied annually.
Real-World Examples
-
Capital Loss Carryover: Selling stocks at a $10,000 loss lets you immediately deduct $3,000 against income; the remaining $7,000 carries forward, reducing taxable income in future years. See our detailed article on Capital Loss Carryover.
-
Charitable Contributions: If you donate $25,000 in one year but your deductions are limited to 60% of your AGI (say $20,000), you can carry forward the excess $5,000 for up to five additional years.
-
Net Operating Loss (NOL): Businesses with losses can apply these losses to offset taxable income in prior or future tax years, helping smooth tax burdens. Visit our Net Operating Loss (NOL) page for details.
Who Benefits from Tax Carryovers?
Tax carryovers mainly help:
- Investors facing capital losses exceeding current deduction limits
- Donors making large charitable contributions beyond annual deduction caps
- Business owners experiencing net operating losses
- Taxpayers with credits phased out by income limits
These provisions offer a helpful way to manage taxes across fluctuating income years.
Tips and Best Practices
- Maintain accurate records of carryovers each year using IRS forms like Schedule D or Form 1045.
- Plan large expenses or donations to maximize use of carryovers in years where you can benefit most.
- Use tax preparation software or consult a tax professional to properly track and apply carryovers.
- Be mindful of expiration periods for certain carryovers to avoid losing benefits.
Common Mistakes to Avoid
- Forgetting to report carryovers on future tax returns, resulting in overpayment
- Misunderstanding limits or expiration dates of carryovers
- Confusing carrybacks (applying benefits to earlier years) with carryovers (applying to future years). For comparison, learn more about Carryforward vs Carryback and Carryback.

A: No. Most credit carryovers have defined time frames, often ranging from 5 to 20 years, depending on the credit.
Q: Do all deductions allow carryovers?
A: No. Only specific deductions like capital losses and charitable contributions exceeding income limits have carryover rules.
Q: How can I find out if I have carryovers?
A: Review previous tax returns, IRS forms, and consult with tax software or professionals. IRS forms such as Schedule D and Form 1045 reflect carryover amounts.
