Question

How much money is allowed to put in your bank account without the IRS getting suspicious?

Answer 1

IRS doesn't get suspicious unless something odd is brought to its attention.  Large cash deposits are reported but if they are from a business that normally deals in a lot of cash, no big deal.

Answer 2

I suggest you don't add any more to your account than you claim as income on your tax return, and actually quite a bit less to avoid suspicion.

Answer 3

Any cash deposit of $10K or more is automatically reported.  Other than that, you can have as much money flowing in and out of your account without trouble from the IRS unless you have been flagged for some reason.
