If you ever wondered this. The answer is ONE day.
Thursday – sent check at noon
Friday – check arrived and cashed
Saturday – check clears bank
I am amazed at the speediness of this operation.
This is one area of government that is functioning like a well oiled machined. The USPS for delivering the mail in a speedy manner, and the IRS for processing the mail.
I am glad my tax payments cleared so quickly. It calms my nerves a bit knowing my obligations are taken cared of.
