Welcome, @Anonymous. 
From a scoring perspective, actual charges will count toward your current balance. Your current balance at reporting time is what hits your report.
Your deposit would reduce your available credit, i.e. you'll have less room to charge stuff. But that number doesn't get reported.
In your case, I'm concerned that you're coming within $4 of your limit. Do you have any other options, such as using different payment methods for the deposit and the rental itself?

First time poster and new credit card user here. I'm planning a trip out-of-town for work and hoping to put the balance of a rental car for a month on my credit card, rather than my debit card. The car's total cost is $647, but with the hold that the company places I think it'll come to $1496. If my credit limit is $1500, but I pay off the balance I put on the card by the end of the month, will this still negatively affect my credit? I heard it's unadvised to exceed a 30% ratio. Any advice is appreciated.
Most credit cards report the balance as of the statement date. But there are a few exceptions, so we would need to know with lender you use.
