Is there something special I need to do to endorse a personal check over to my business account?

I don’t think it’s a big deal.
You could sign over the check to your business if the bank won’t let you deposit the check directly.

@The_Compassionate_Heretic That’s what I’m wondering about… how does one “sign over” the check to the business?

I would just write your business name next to your name on the check.

If that doesn’t fly, then deposit it into your personal checking account and out of that account write your business account a new check.

@prince Where you would normally endorse the check, you can write “pay to the order of <business name> and then sign it.
I would imagine that would not be necessary but if it is, that’s how you do it.

Some banks have come up with a rule that you can’t deposit third party checks, which is a check made out to one payee in another payee’s account. I don’t know if that would count if you are the same person.

They probably would, but I think it would be easier to just put it in your personal account, and then write a check to your business account.

We do that a lot when transferring money between accounts in our household, because most our accounts are interest bearing, and we get interest on the same money twice by depositing both checks on the same day.
