This next application is one that is meant to provide professionals of all fields with a picture of their actual income. The Income Tax Estimator is a program that provides a highly detailed and highly comprehensive look into actual income tax returns (Zamora, 2009). The application allows the user to identify the actual amount of tax that has to be deducted from the revenues generated and also allows the user to develop a picture of any returns that may possibly be coming from taxes.What sets the Income Tax Estimator apart from rudimentary tax calculators is the fact that it does not merely calculate the tax as a certain percentage of the income but allows the user to take advantage of the intricate details of the income tax system that are a part of the application. This is brought about by allowing the user to enter in data about the income and generate estimates of income tax on the income (Zamora, 2009). The application also allows the user to save the data entered along with the estimates derived for future reference. An added option comes in the form of the fact that the user can edit and re-estimate the entered data to their preferences at any time. The Income Tax Estimator also periodically alerts the user of the approaching date by which income tax dues have to be cleared if the user chooses.
