"The IRS considers a single member LLC to be a disregarded entity. Therefore, the owner of the business can not make contributions to the business. Period." is a very authoritative statement. It is also 100% WRONG.
I had to shut down my first LLC, formed in 2019, after taking to an advisor and then a lawyer who pointed out that since I never documented capital contributions to my LLC, I had no (or very weak) personal legal protections for any claims against my business.
I believe every state is different, but the IRS wants to see clear documentation showing where money came from into the business and where money went out.
As previously pointed out: it is neither income nor business expense to transfer money too and from your separate business account, so nothing to report on taxes but very thorough records are important.
Don't take my word for it and don't get your legal advice from a tax software blog. Pay a few bucks to get professional advice; in 2025, it doesn't cost as much as you might think.
one more nugget: It was pointed out to me that unless I want "LLC" on my name, which I do, an LLC is a waste of money and a headache when starting out. Just form a sole-proprietership and get some liabiility insurance. Depending where you are, insurance might be a lot cheaper than anual LLC fees/taxes.
