How to Enter Capital Loss Carryover in TurboTax

A capital loss carryover is a valuable tax deduction that can save you money for years. If you had investment losses in a prior year that exceeded the annual deduction limit, you need to report them in your tax software. This guide provides step-by-step instructions on where and how to enter your capital loss carryover in TurboTax, helping you claim all eligible deductions.

What is a Capital Loss Carryover?

Before entering the amount, understand what it means. When you sell an asset-like stocks, bonds, or real estate-for less than your purchase price (your "cost basis"), you have a capital loss. The IRS lets you use these losses to offset capital gains.

If your losses are greater than your gains for the year, you can deduct up to 3,000 of the excess loss against your other income (like your salary). If your net capital loss is more than 3,000, the remaining amount becomes a capital loss carryover that you can use in future tax years.

Here’s an example:

• In 2023, you sold stocks and had a net capital loss of $12,000.
• On your 2023 tax return, you used $3,000 of that loss to reduce your taxable income.
• The remaining 9,000 (12,000 - $3,000) is your capital loss carryover for your 2024 tax return and later.

This carryover amount does not expire. You can carry the loss forward indefinitely until you fully use it against future capital gains or with the annual $3,000 deduction.

Finding Your Capital Loss Carryover Amount

The amount you carry over comes from your prior year's tax return. You cannot calculate it from scratch this year; you must use the official figure from last year’s forms. Recalculating or guessing the amount is a common mistake.

Here’s where to find it:

1. Locate last year's tax return. You need the complete return, not just Form 1040.
2. Find your Schedule D (Capital Gains and Losses). This form summarizes your investment sale activity.
3. Look for the "Capital Loss Carryover Worksheet." This worksheet is the official source of your carryover figure. For recent tax years, this worksheet is typically in the IRS Instructions for Schedule D, but your tax software from last year should have generated and saved it as part of your completed return PDF.

On that Capital Loss Carryover Worksheet, you will find two key numbers for TurboTax:

• Short-Term Capital Loss Carryover: Often on line 6 or 14 of the worksheet, this is the remaining loss from assets you held for one year or less.
• Long-Term Capital Loss Carryover: Often on line 14 or 22, this is the remaining loss from assets you held for more than one year.

Write down both of these numbers. It's important to distinguish between short-term and long-term amounts because they offset gains differently.

If you cannot find your prior year's return, you can usually download it from the tax software provider you used last year. If that is not an option, you can request a tax return transcript from the IRS website for the specific tax year you need.

Step-by-Step Guide: Entering the Carryover in TurboTax

Once you have your short-term and long-term carryover figures from last year’s return, you are ready to enter them. TurboTax makes this process simple once you know where to look.

Step 1: Get to the Right Section

The quickest way to get to the correct screen is by using the search function. After signing into your TurboTax account and opening your return:

1. Click the search icon in the top right corner.
2. Type "capital loss carryover" into the search box.
3. A result will appear that says "Jump to capital loss carryover." Click it.

Alternatively, you can go there manually:

1. Go to the Wages & Income section (it might be called Federal Taxes or Income & Expenses depending on your TurboTax version).
2. Scroll down to the Investments and Savings section.
3. Click "Show more" or the arrow to expand this section.
4. Find the line for Capital Loss Carryover and click "Start" or "Revisit."

Step 2: Answer the Initial Prompt

TurboTax will ask questions. The first screen will likely ask, "Do you have a capital loss carryover from 2023?" or "Did you have investment losses in 2023 that you couldn't deduct?"

Click Yes.

Step 3: Enter Your Short-Term and Long-Term Loss Amounts

On the next screen, you will input the numbers you found earlier. You will see two clearly labeled boxes:

• A box for your short-term capital loss carryover from the prior year.
• A box for your long-term capital loss carryover from the prior year.

Carefully enter the numbers from your prior-year Capital Loss Carryover Worksheet into the corresponding boxes. If you only have one type of carryover (for example, long-term but not short-term), enter zero in the empty box. Do not leave it blank.

Double-check that you’ve put the right number in the right box. Mixing them up can cause tax calculation errors, as short-term losses and long-term losses offset gains in a specific order. Once you confirm the numbers are correct, click "Continue."

That's it. TurboTax will automatically apply this carryover to your current year's tax return. It will first use the losses to offset any capital gains you have this year, following IRS netting rules. If a loss remains, it will apply up to $3,000 of it as a deduction against your ordinary income.

Common Mistakes to Avoid

This process is straightforward, but small oversights can create problems. Be aware of these common errors:

• Guessing the Amount: Never estimate or try to recreate your carryover loss amount. The IRS expects you to use the exact number from your prior return. Using a different number can trigger a review.
• Forgetting About It: Some people forget they have a carryover and never claim it. This means missing out on a valuable deduction. The carryover is an asset; make sure you use it.
• State Differences: Most states with an income tax follow federal rules for capital losses. However, a few states have different carryover rules or separate deduction limits. As you complete your state return in TurboTax, pay attention to any questions about capital loss carryovers to ensure the figure is applied correctly there too.

Final Thoughts

Entering your capital loss carryover is an important step to reduce your tax liability for both this year and future years. By locating your carryover amounts from last year's tax return and carefully entering them into TurboTax, you ensure the deduction is correctly applied against gains and ordinary income.

While software like TurboTax is good for data entry, tax professionals often handle more complex client situations such as tax-loss harvesting, entity restructuring to optimize losses, or interpreting multi-state carryover regulations.
