Estimated tax payments are due on 9/15.  You need to pay 90% of your current year's tax obligations through estimated payments or through withholding to avoid a penalty.  Alternatively, you can pay 100% or 110% of your prior year's tax obligation (110% if your AGI is over $150,000).  If you think your income is equal or less than 2007, you can have your CPA or tax accountant do a tax estimate to determine a smaller payment.  Don't forget.
