An Employment Verification Letter for the Self Employed is an official document that confirms an individual’s employment status and earnings. These letters are usually requested by landlords, lenders, and insurance companies to confirm a person’s income source and job status. Self-employment verification letters are also sometimes needed when applying for certain government benefits or business contracts. A letter of self-employment verification should include details such as length of employment, job description, income earned and taxes paid. In addition, the letter must be legally signed and dated in order to be accepted as evidence of employment.
