Business account - High Yield Savings

I set money aside every month to pay taxes at the end of the year. I’m looking for a financial product I can store all this money so I make a little on it during the year, withdrawal to pay taxes, and continue to transfer funds into for the following year.

I’ve looked into CD’s with Schwab but the minimum balance is incredibly high. Can’t seem to find a HYSA for business.

Any suggestions?
