No, it doesn’t. Anything that is not on your credit reports, such as your income or your debt-to-income ratio, does not count in your FICO scores.
Your income does not reflect your credit worthiness, your credit risk, or whether or not you will make your payments. You could make a million dollars a year and that wouldn’t help your credit report one bit. Conversely, you could make $12,000 a year and it wouldn’t hurt your score one bit. It's how you manage your credit that matters.
