Some verifications of employment require that all of the income values are filled in their entirety, while other loan programs only require that the employment itself is verified, with no income values listed.

Normally a Verification of Employment or VOE is done by both the processor for the mortgage broker and the underwriter for the lender. There is a simple form they fill out over the phone with some one who works in the Human Resources department of your office.

If self employed, the easiest way to prove your employment is to provide a business license. In most instances you'll need to show that you have been licensed for at least 2 years.

If you are self employed there are other ways to verify your employment. One popular way is to have your Accountant provide you with a 'CPA letter'. The accountant can affirm that you are in fact self employed, that he has prepared your taxes for the past few years, and your average annual income.

A verification of employment, also referred to as a VOE, can be done either verbally or through a form that is either mailed or faxed over to an employer. Some lenders require written VOE's and other lenders allow verbal VOE's. A VOE is generally required in addition to other normal income documentation, such as W2's, income tax returns, and pay-stubs.

Depending on your lender, a VOE may or may not be required.
For some lenders, a recent paystub is all that's needed to verify employment.
