Estimated Tax Payments

Individuals:

There are two ways to pay your income taxes- through withholding, like on wages, or by making estimated tax payments. Estimated tax payments for individuals are due kind of quarterly on April 15th, June 15th, September 15th and January 15th of the following year.

If Your Income Is Less Than Last Year

The amount of estimated tax you are supposed to pay is 90 % of what you “estimate” you will owe for that year, say 2009. You compute how much you think you will owe, then divide by four and pay that amount. Just use your tax return software for last year and put in your numbers for this year. This is a good method to use if your income in 2009 is a lot less than that of 2008.

If Your Income Is the Same or Higher Than Last Year

But if your income is about the same or higher than last year you should use one of the “exceptions” to penalty for underpayment of estimated tax. That is, pay an amount equal to 100 % of prior year’s tax. (You can pay less but I don’t recommend it- it’s temporary and you never know what they’re going to do with the tax code.) Take the tax on your 2008 1040 line 61, divide by four and pay that each quarter. Then you’re covered- even if you owe $ 1 million on April 15, 2010 you won’t get a penalty. If your prior year’s tax was zero, then that’s all you have to pay for estimated- zero. But be careful, you’ll have to include form 2210 with your return to prove it.

Corporations:

The rules for estimated tax payments for corporations are a little bit different from those for individuals. For a calendar year corporation (one whose tax reporting year ends on December 31) the estimated tax payments are due on April 15th, June 15th, September 15th and December 15th of the current year.

So, use the same rules as above for individuals, i.e., estimate the corporation’s actual tax if income is less than prior year or pay an amount equal to 100 % of prior year’s tax if income is equal to or greater than the prior year.

Unfortunately the “exception” to penalty for underpayment of estimated tax that allows you to pay zero if prior year’s tax was zero is not available to corporations. Attach completed form 2220 to the corporate return to prove your exception.
