I never know what I'm going to make and that guessing game becomes more crazy as time goes on. With one search engine update here and there, one can go from $100 a day to $25 a day to $2,000 a day. And you never know how long it will last til the next ranking shake up dramatically alters the landscape of your business and pocketbook. In the last several months, my rates have gone from middle class to the highest tax bracket and then the poor house. It can be quite a rollercoaster.
Estimated quarterly payments are the self-employed person's tax-withholding equivilent. If an employer doesn't withhold enough, the employee doesn't pay penalties.. they just pay the difference.
If you don't have a good relationship with an accountant, you might want to either download the estimated tax instructions from the IRS, or if you use one of the DIY tax return packages, they generally have good calculators that walk you through what you should need to estimate. Also, keep in mind that you can vary the amount of estimated tax you pay each quarter as your annual income becomes clearer.
But, I'm not an accountant.
I am a engineering consultant with self-employement income (much the same as most non-incorporated internet businesses. Each year I meet with my lawyer to do my taxes. After he enters all of the information into his computer program and it calculates my taxes for the past year it then calculates the estimated taxes for this year, based on my taxes for last year.
My income varies greatly from year to year. The economy has had its ups and downs (hoping for an up for a change), and also I have problems like having heavy travel expenses (and deductions) in one year for a project and receiving the payment the following year. So the first years income is low. The second year the income is higher (big check, no deductions). So the estimated taxes that year are too low (based on the pervious year, with low income). However, as long as I pay the estimated tax based on the previous year's tax I am OK.
The lesson: If you have income from web (or other) activities other than a "real" job with tax withholding, see a lawyer or accountant. They know the details. They can also help with finding deductions. It is well worth the cost.
