What is a proof of income letter?
A proof of income letter (or income verification letter) is a signed document confirming how much a person earns and their employment status. Landlords, banks, lenders and government agencies ask for one to verify that an applicant can afford rent, a loan or a service. It is usually written by an employer, accountant, or the person themselves if self-employed.
