What Are At-Risk Rules?


The at-risk rule deals with the amount of your investment in a business that you are personally at risk of losing if the business fails. In other words, this rule has nothing to do with whether the business itself is at risk but rather what you, personally, are at risk of losing.

Purpose of the At-Risk Rules

The purpose of the at-risk rule is to prevent you from claiming a loss in excess of what you actually stand to lose. Only the amount you are personally at risk of losing counts towards your at-risk basis, which is also called your tax basis.

Your Tax Basis

Your initial tax basis is in an S corporation is equal to your investment in the business plus loans you make to the business. For example, if you own an S corporation and invest $10,000 in the stock and also lend the S corporation $5,000, your tax basis would be $15,000 and is the amount you have at risk. The amount you invest in the capital stock is called your stock basis and the amount you lend the company is called your debt or loan basis.

S corporations

If you invest in an S corporation or partnership, the amount of a loss incurred by these entities that you may deduct on your individual income tax return is limited to the amount of your investment your at-risk basis.

Example
  • You start an S corporation In 2020.
  • You invest $10,000 in the stock of your S corporation.
  • You are the sole shareholder/employee.
  • You have not made any loans to the S corporation.
  • In 2020 the S corporation has a $12,000 loss.

Result: Your tax basis equals your stock basis plus your loan basis (which in this case, there is none).

  • Your tax basis equals your stock basis, $10,000.
  • Since you did not make any loans to the S corporation during 2020, your at-risk basis is also $10,000.
  • Since your 2020 tax basis is $10,000, you may only deduct $10,000 of the $12,000 loss.
  • The $10,000 loss deduction is subtracted from your stock basis, reducing your tax basis to zero (stock basis $10,000 minus $10,000 loss deduction).
  • Since you're only allowed to deduct $10,000 of the $12,000 loss for 2020, the remaining $2,000, which is called a suspended loss, may be carried forward indefinitely until there is sufficient basis to absorb it or when you dispose of the business.
  • Increasing Your Tax Basis

    Continuing with the above example where you had a suspended loss of $2,000:

    Suppose you wanted to deduct the entire $12,000 loss in 2020 instead of just $10,000. This could be done by increasing your tax basis in by at least $2,000 during 2020. You may do this by investing an additional $2,000 in the stock of the S corporation or by lending the S corporation $2,000 for which you would be personally liable to repay.

    If you were to lend $2,000 to the S corporation instead on investing $2,000 in S corporation stock, you would have a loan basis of $2,000 and a stock basis of $10,000 which would equal the $12,000 tax basis needed to deduct the entire $12,000 in 2020.

    TIP:

    If you expect a loss in any given tax year, check your stock basis and loan basis (if any) prior to the end of the year to see if you will have enough basis to absorb the anticipated loss. If you don't think you will have enough basis, give yourself enough time to increase your tax basis before the end of the year.

    Form 6198

    If you have a business loss and if any part of your investment in the business is not at risk, you must complete Form 6198, At-Risk Limitations.

    Sole proprietorships

    If you're a sole proprietor, you and your business are not considered separate entities; you and the entity are considered one and the same and you would file Schedule C (Schedule F for farming) to report business income and expenses.

    For Schedule C filers, at risk means you are using your own money for the business. Only check Box 32a if "All investment is at risk". Check box 32b if "Some investment is not at risk". A loss may only be deducted up to the amount you personally have at risk. If a loss exceeds your at-risk investment, the excess amount is a suspended loss and may be deducted in a future year indefinitely, until you have sufficient at-risk basis to absorb the loss.

    Amounts Invested in the Business for Which You Would Not Be At Risk May Include:
    • Non-recourse loans used to finance the business
    • Cash, property or borrowed amounts used in the business that are protected against loss by a guarantee, stop-loss agreement, or other similar arrangement (excluding casualty insurance and insurance against tort liability).
    • Amounts borrowed for use in the business from a person who has an interest in the business, other than as a creditor.

    In other words, if you have no money at risk in your business, you may not deduct any part of a Schedule C loss. The amount of a loss you may deduct must be equal to or less than the amount you personally stand to lose.
