What Is Form 1120-L

Form 1120-L is one facet of the suite of forms used by the Internal Revenue Service (IRS) specifically designed for life insurance companies to report their annual income and expenses. This form allows such entities to calculate their taxable income and any taxes due or overpayments that need to be refunded. Life insurance companies must consider a unique set of financial circumstances and regulations, which is why this specialized form is crucial for their tax reporting obligations.

  • The life insurance company has taxable income adjustments tied to the insurance industry.

Life insurance companies operating in the United States use this form to comply with federal regulations, regardless of their size or the complexity of their financial activities.
