quick tax help

[Taylor Caby]

I'm not sure I understood my CPA correctly when he answered this question the first time and I'm having a hard time getting ahold of him.

I am filing for an extension for 2006 taxes. I have had a fairly large amount of income in 2006 and have been up to date on 110% of my taxes for 2005 for my estimated payments in 2006. I will certainly owe more though once we figure out exactly what that is.

-Do I need to send in what i "expect" to owe in addition to my 110% of 2005's estimated payments (which i already paid) tomorrow? How do i estimate this number and do i need to send it in tomorrow?

-I know i need to pay my first qtr 2007 estimate. I am sending that in tomorrow morning, but how do I estimate that? I don't have my total 2006 income calculated yet due to the extension. Do I just make a guess?

Thanks,
tc
