Disability insurance benefits may or may not be subject to income tax, depending on how the premiums were paid. If the premiums were paid with after-tax dollars, then the benefits are generally not taxable. However, if the premiums were paid with pre-tax dollars, such as through an employer-sponsored plan, then the benefits are typically taxable as income. It's important to note that this applies to individual disability insurance policies and employer-sponsored group disability insurance plans. The tax treatment of disability insurance benefits can vary depending on the specific circumstances, so it's always a good idea to consult with a tax professional or refer to the IRS guidelines for more information.
