Quarterly Tax question

[smittymatt]

As a professional gambler, am I forced to declare and pay taxes quarterly, or can I just declare for the entire year each year on April 15th. What if I declare as recreational? I'm asking now because the quarterly deadline is coming up on June 15th, but I will be at the WSOP during this time and have to get this settled before tomorrow when I leave... yes, I'm a horrible procrastinator.

If you don't pay quarterly, they will just charge interest and compute your amount owed accordingly.
