In the most general sense, a liability is anything that is a hindrance, or puts individuals at a disadvantage.

Accounting liability

In financial accounting, a liability is defined as an obligation of an entity arising from past transactions or events, the settlement of which may result in the transfer or use of assets, provision of services or other yielding of economic benefits in the future. Individual or group must adopt corporate charter and file it with the state.

• They embody a duty or responsibility to others that entails settlement by future transfer or use of assets, provision of services or other yielding of economic benefits, at a specified or determinable date, on occurrence of a specified event, or on demand;
• The duty or responsibility obligates the entity leaving it little or no discretion to avoid it; and,
• The transaction or event obligating the entity has already occurred.

Liabilities in financial accounting need not be legally enforceable; but can be based on equitable obligations or constructive obligations. An equitable obligation is a duty based on ethical or moral considerations. A constructive obligation is an obligation that can be inferred from a set of facts in a particular situation as opposed to a contractually based obligation.

The accounting equation relates assets, liabilities, and owner's equity:

Assets = Liabilities + Owner's Equity

The accounting equation is the mathematical structure of the balance sheet.

The Australian Accounting Research Foundation 1 defines liabilities as future sacrifice of economic benefits that the entity is presently obliged to make to other entities as a result of past transactions and other past events.

Probably the most accepted accounting definition of liability is the one used by the International Accounting Standards Board (IASB). The following is a quotation from IFRS Framework:

Regulations as to the recognition of liabilities are different all over the world, but are roughly similar to those of the IASB.

Examples of types of liabilities include: money owing on a loan, money owing on a mortgage, or an IOU.

Classification of accounting liabilities

Liabilities are reported on a balance sheet and are usually divided into two categories:

• Current liabilities  these liabilities are reasonably expected to be liquidated within a year. They usually include payables such as wages, accounts, taxes, and accounts payables, unearned revenue when adjusting entries, portions of long-term bonds to be paid this year, short-term obligations (e.g. from purchase of equipment), and others.
• Long-term liabilities  these liabilities are reasonably expected not to be liquidated within a year. They usually include issued long-term bonds, notes payables, long-term leases, pension obligations, and long-term product warranties.
