Illinois requires a number of taxes for other activities, including utilities taxes, gambling and bingo taxes, aircraft use tax, hotel taxes, watercraft use taxes, automobile taxes, and a number of other licenses and registration fees required throughout the state. 

Within the state of Illinois, amid the plethora of tax forms in connection to the filing of income taxes, there also remains Illinois tax related to sales in contrast to the recognition given to non-profit organizations as well as "charitable games." Illinois tax, that which is imposed upon a retailer's receipts stemming from the sale of "tangible property" for both application as well as consumption," is what sales tax entails. Such Illinois tax falls upon 3 areas of specification according to the state. 

These include "qualifying food/drugs/medical supplies," "vehicles," and another for all "other general merchandise." In order for food to fall under this category, it must have been created for instant consumption, examples of which would be certain products you may find at supermarkets. "Vehicles" include that of the motorized type, such as those that assisted in relocating a business to the state of Illinois. 

"Other merchandise, then, encompasses other tangible property, such as sodas and photo processing fees. The base rates include 1% for qualifying foods and 6.25% for both vehicles and "other" general merchandise. This is subject to variation, however, depending upon "location specific" rates. These local taxes may be imposed by specified municipalities, for instance.

Now that we have covered Illinois tax related to sales, we must venture towards areas in which Illinois tax law may leave exempt. One such category is that which non-profit organizations fall into. 

In order to apply for an "Exempt (E) number, the organization must convey a letter of request as well as the following pertinent documents: "articles of incorporation if applicable, a constitution if unincorporated, by-laws, an IRS letter acknowledging the organization's exempt status, most recent financial statement, concise explanation of the organizations purpose and functions, brochures or other organization-related materials, as well as any other materials that present information specific to the non-profit. 

Charitable games present another area connected to such purposes, however, does receive taxing upon its "gross proceeds." In total, 14 games are allowed to be conducted in relation to this Illinois tax law. Some examples include black jack, craps, poker, and merchandise wheel. Earnings from these games must be put toward the organization's mission, such as that of charity or education for instance.

Eligibility to organize and run such charitable games includes the following qualifications. The organization must be either "religious, charitable, educational, veteran-related, or labor organization-related." They must have been in operation for a minimum of 5 years. In addition members must not be garnering profit, and they must already have been classified as exempt under a number of sections of "Internal Revenue Code." 

In order to satisfy requirements by the state of Illinois, the appropriate Illinois tax forms must be filled out. Also, license fees must be paid to ensure the licensing of such activities. One yearly application is enough to satisfy as many as 4 charitable games events. Despite its status as "charitable," such games are not wholly exempt from taxes.
