Thanks, TaxPhd. I also checked the IRS web site (
http://www.irs.ustreas.gov/prod/forms_pubs/forms.html ), and (based upon the year 2000 form 1040-ES), the following is current law for 2000 estimated taxes, regarding the 'safe harbor':
"In most cases, you must make estimated tax payments if you expect to owe at least $1,000 in tax for 2000 (after subtracting your withholding and credits) and you expect your withholding and credits to be less than the smaller of:
1. 90% of the tax shown on your 2000 tax return, or
2. The tax shown on your 1999 tax return (108.6% of that amount if you are not a farmer or fisherman and the adjusted gross income shown on that return is more than $150,000 or, if married filing separately for 2000, more than $75,000).

Dennis, you should do what you're comfortable with ... tax planning gets pretty 'nerdy', and requires a pretty tight ship. To be honest, my 'ship' is often not as tight as it should be, and I simply make sure I've paid in just a little more than necessary based upon my reasonable estimate. However, the advice above remains true - the smart cookies pay only what they must, and invest the difference until the piper must be paid on April 15.
I should also mention the usual hedge: 'everyone's tax situation is different, so you should consult with your own tax professional' ...
