Deferred revenue is not usually considered a current liability. It is generally classified as either a long-term liability or a component of equity. Deferred revenue is income that has been paid in advance for goods or services that have not yet been delivered. In essence, it is a promise to fulfill an obligation in the future.
For example, when a customer pays for an annual subscription to a magazine, the company records the money as deferred revenue. This is because the company has not yet provided the goods (the magazine subscription) to the customer and thus has a future obligation to do so. The company can then record the customer payments as deferred revenue until the goods are delivered and the obligation is fulfilled.
Therefore, deferred revenue is not a current liability but rather a “promise to deliver goods or services in the future.” It still must be reported on balance sheets as either a long-term liability or a component of equity.
