<prompt> Human: Ive had a few emails over the last 6 months from my credit card company asking me to update my income to help them assess eligibility for a credit line increase.I earn significantly more since I last updated it 15 years or so ago, but I dont need additional credit. In fact, I dont really need it at all, and just use it our of convenience.Are there any upsides to updating this? E.G. My credit used to credit available ratio decreases. Or should I just ignore them?Thanks!  <response>: You hit the nail on the head -- theyll likely raise your limit on your card. That can potentially improve your credit score, depending on where your credit utilization ratio is at right now. But, its not necessary you share it and if you think it will tempt you to spend more and go into debt, then dont do it. Theres not any other real con to it though, unless you just dont want to share that info with a company generally.
