Sales Tax:

Iowa-6.00% + Local Tax (Bettendorf 1.00%, Davenport 1.00%)
(Food and drugs exempt)

Illinois-6.25% + Local Tax (Moline 1.00%, Rock Island .75%, East Moline .50%, Silvis .50%)
(1.00% - Food and drugs)
Personal Income Tax:

Iowa:


Escalating tax scale from .36% to 8.98%. The 8.98% tax bracket starts at $62,056 of taxable income. Numerous deductions from state tax are allowable, including federal income taxes paid and certain itemized deductions such as property taxes, interest, etc. Dual income families can submit a “married filing separately” return thereby decreasing the tax rate. A partial exemption is provided for Retirement Income. The exemption is up to $12,000 for joint filers and up to $6,000 for all other filers. In order to use this exemption, the taxpayer must be 55 years or older, disabled, or a surviving spouse or a survivor having an insurable interest in an individual who would have qualified for the exemption. Iowa generally follows the Federal Internal Revenue Code to determine income and deductions. Only a maximum of 50% of the Social Security income is subject to tax.

Illinois:


Flat rate of 3% based on federal adjusted gross income excluding Social Security and Retirement Income and after certain other adjustments. Illinois does not allow itemized deductions. However, there is a $2,000 deduction for each Illinois exemption. There is also a credit for 5% of the real estate taxes paid on a taxpayer’s personal residence.

Reciprocity:


Iowa and Illinois have reciprocity with each other. Therefore, Iowa and Illinois residents are deemed to have earned wage income in their state of residence, and not their state of employment if they are employed in Iowa or Illinois.

Real Estate Property Taxes:

Difficult to make generalizations due to variance between cities and counties within Iowa and Illinois. These taxes are potentially somewhat less in Iowa.

Gain On Sales Of Residences:

For federal, Iowa, and Illinois tax purposes, taxpayers may exclude gain on sale of their principal residences once every two years, subject to ownership and use tests, as follows: single taxpayers up to $250,000 and married taxpayers up to $500,000. Gains in excess of these amounts are taxed at capital gains rates on federal returns, and at regular rates on Iowa and Illinois returns.

Note:


Tax impact of one state versus another requires a case-by-case analysis by a knowledgeable tax advisor.
