Thanks for the advice. I've had the same exact question about quarterly estimated tax payments. Could you add links to the sources where you got this information such as the IRS? I'd like to investigate some of the topics further. Where did you learn about this information? From your fight with the IRS? Do you know of any book or guide on taxes for small businesses?
