The at-risk rules are IRS tax guidelines that limit the amount of business or investment losses you can deduct on your tax return. They ensure that you can only deduct a loss up to the actual amount of money or property you personally stand to lose in an activity. In short, you cannot claim a tax deduction for a loss using money that was never truly yours to lose.

1. Meaning of “At-risk rules”

In the past, some investors bought into heavily debt-funded business ventures (often called “tax shelters”) using loans they were never personally required to pay back. They would then claim massive tax deductions for business losses, even though their own wallets were completely safe.

To stop this, the IRS created the at-risk rules. “At-risk” simply means you have real financial skin in the game. For tax purposes, your at-risk amount includes your own cash invested, the value of the property you contributed, and any business debt that you are personally legally liable to repay (known as recourse debt).

2. Why “At-risk rules” Matters

These rules matter because they act as a ceiling on your tax deductions. When you invest in a business or a rental property, it may experience a loss during the tax year. Normally, business losses are valuable because they can offset your other income and lower your overall tax bill.

However, if the IRS determines that your share of the business loss is larger than your actual at-risk amount, your deduction gets capped. You will not be able to write off the full loss that year, which could result in you paying more in taxes than you originally anticipated.

3. How “At-risk rules” Works

When you participate in a business or investment, you establish an “at-risk basis.” This number goes up when you invest more of your own cash or take on debt that you personally guarantee. It goes down when the business distributes money to you or when you claim a loss deduction.

When tax time arrives, you compare your business loss to your at-risk amount. If your at-risk amount is higher than the loss, you can typically deduct the full loss (subject to other tax rules). If the loss is larger than your at-risk amount, you can only deduct up to the amount you are at risk for. The leftover loss doesn’t disappear; it gets “suspended” and carried forward to future tax years until your at-risk amount increases.

4. Simple Example of “At-risk rules”

Let’s say you invest $10,000 of your own savings into a new partnership. The partnership also borrows $50,000 to buy equipment. However, the loan is nonrecourse, meaning the bank can only take back the equipment if the business fails—they cannot come after your personal bank account. Therefore, your “at-risk” amount is just your original $10,000.

In the first year, the partnership struggles, and your share of the business loss is $15,000. Because of the at-risk rules, you are only allowed to deduct $10,000 (the amount you actually have on the line). The remaining $5,000 loss is suspended and carried forward to next year.

5. Who Is Affected by “At-risk rules”?

The at-risk rules apply to almost any trade, business, or income-producing activity. The taxpayers most commonly affected include:

Sole proprietors and freelancers (filing Schedule C)
Partners in a Partnership
Shareholders in an S Corporation
Real estate investors and landlords (filing Schedule E)
Farmers (filing Schedule F)
Certain closely held C Corporations

6. Common Mistakes Related to “At-risk rules”

Confusing the types of debt: Assuming that all business loans increase your at-risk amount. Only debt you are personally liable for (recourse debt) generally counts.
Losing track of suspended losses: Forgetting to carry forward disallowed losses to future tax years when your at-risk amount might have increased.
Mixing up at-risk and passive rules: Thinking that because you actively manage a business, you don’t have to worry about at-risk limitations. Your time spent managing doesn’t matter if you don’t have financial risk.
Not tracking distributions: Forgetting that taking cash out of the business lowers your at-risk amount, which could trigger a surprise tax bill if your at-risk amount drops below zero.

7. Forms Related to “At-risk rules”

If you have a loss from an activity and you are not completely at risk for your entire investment, you generally have to deal with the following forms:

Form 6198 (At-Risk Limitations): This is the primary IRS worksheet used to calculate your current year profit or loss, figure out your exact at-risk amount, and determine your allowable deduction.
Schedule C, E, or F: These forms (used for business, rental, and farm income) all contain a specific checkbox asking if all of your investment in the business is at risk.

8. “At-risk rules” vs. Related Terms

At-Risk Rules vs. Passive Activity Loss Rules: At-risk rules test your financial exposure (can you personally lose money?). Passive activity rules test your time exposure (do you actively work in the business?). To deduct a loss, you must clear the at-risk hurdle first, and then the passive activity hurdle second.
At-Risk Basis vs. Tax Basis: Your tax basis is your total investment for tax purposes, which includes both debt you are responsible for and debt you aren’t. Your at-risk basis is usually lower, as it strips away the debt you aren’t personally liable for.

10. FAQs About “At-risk rules”

Does a mortgage on a rental property count as at-risk?
Usually, nonrecourse debt does not count toward your at-risk amount. However, there is a special exception in real estate for “qualified nonrecourse financing.” If the loan comes from a standard commercial lender and is secured by the real estate, the IRS generally allows it to be counted as at-risk.

What happens to my losses if they are limited by the at-risk rules?
They are not permanently lost. Disallowed losses become “suspended” and carry forward indefinitely. You can use them in a future tax year if your at-risk amount increases, or when you sell your interest in the business.

Do I have to file Form 6198 every year?
You only need to file Form 6198 if you have a loss in an activity and a portion of your investment is not at risk (for example, you used nonrecourse loans or stop-loss agreements). If your business is profitable, or if every penny invested is fully at risk, you typically do not need the form.

Do the at-risk rules apply to traditional employees with W-2 income?
No. The at-risk rules apply to business owners, investors, and partners who claim business and investment losses. They do not apply to standard W-2 wages.

11. Final Takeaway

The at-risk rules are a fundamental IRS safeguard designed to keep tax deductions realistic. They ensure that you can only write off business or investment losses up to the amount of money you actually stand to lose. Understanding the difference between money you are personally responsible for and money you aren’t is essential for accurately forecasting your tax deductions and avoiding surprises at filing time.
