### Annualized Income Installment Method Definition

An Annualized Income Installment Method is a tax reporting method that helps taxpayers effectively and accurately estimate their taxes. This method calculates an employee’s (taxpayer’s) estimated tax and helps to reduce the underpayment they might have incurred as a result of fluctuations in income.

In the United States, taxpayers who do not have a steady income can have part of their paychecks withheld for tax purposes. Self-employed individuals or business owners can also set a part of their income aside or pay a lump sum as an installment payment for part of all of their estimated taxes. There are three basic methods for installment payment of tax that the Internal Revenue Service provides.

### A Little More on What is the Annualized Income Installment Method

The annualized income installment method as used by taxpayers in the United States aids an accurate assessment of taxes. This method calculates annual tax amount on installment in order to minimize cost of revenue as well as fluctuation of income due to penalties.

For a taxpayer that pays quarterly, the accurate amount to be paid is realized by dividing an annual tax amount into four parts. However, to enhance an effective use of the annual income installment method, the Internal Revenue Service provides taxpayers with necessary tools and materials for calculation. The 505 publication of IRS contains worksheets and forms that taxpayers can use. The table 2210 IRS is also introduced but because it is a bit complex, calculations are done on the IRS datasheet.

For example, if taxpayer Charles and Harrison have \$200,000 as their annual estimated tax. This is divided quarterly, making a sum of \$50,000 every quarter. If charles receives his revenue with an income of 25% every quarter, tax payments can be made on schedule.

Harrison on the other hand with an imbalance income can pay 0%, 20%, 30% and 50% in each quarter. He has four different amounts that can together make up the overall annual tax estimation. If Harrison makes payments that partly coincide in time, he can establish his donations in such a way that they can be accompanied by his income. However, calculating this contribution in this way is quite technical, it is mostly done by experts.
