The state of Illinois has a Personal Income Tax. When you pay wages to your Illinois employees, those employees will have an Income Tax obligation with the Illinois Department of Revenue on the wages that you pay them. The Department of Revenue wants to make sure that they get the taxes due them from your employees.

This includes both filing reports and paying the Withholding amounts on a regular basis, usually quarterly. Income Tax is withheld from employees' wages. There are no employer contributions.

Generally, if someone who works for you is considered to be your employee for Federal Income Tax purposes, that person is also considered to be your employee for Illinois Income Tax purposes.

Illinois Employer Income Tax Withholding information

As an Illinois employer you are also required to withhold Federal Payroll and Income taxes from your employees' wages. Payroll taxes include Social Security and Medicare taxes. Employers send the withheld amounts to the federal government.

The US Internal Revenue Service requires that every employee must provide an employer with a signed withholding exemption form, IRS Form W-4, on or before the date of employment. The employer must then submit Form W-4 to the IRS. Employers use Form W-4 to determine how much Income and Payroll Tax to withhold from each employee's wages. Note that independent contractors are not considered to be employees.

The amount withheld for each employee is expected to be the employee's approximate tax obligation to both the state of Illinois and the federal government.

The Illinois Unemployment Insurance program is administered by the Illinois Department of Employment Security.

Illinois Unemployment Insurance is an employer obligation. Payments are not deducted from an employee's wages. The Illinois Unemployment Insurance program is part of a nation-wide program administered by the US Department of Labor. Unemployment Insurance provides temporary payments to individuals who are unemployed through no fault of their own.

Unemployment Insurance is, like other insurance policies, a numbers game. Employer tax liability is based on a percentage of each employee's wages. When a new Illinois employer registers for Unemployment Insurance, the state has no numbers on which to base the percentage. First time Illinois employers are assigned an introductory rate based on the type of business and number of employees among other factors.

After the state has had enough time to compile insurance numbers on your business (total contributions vs. total paid to former employees over time) they will assign an "Experience Rate" to compute the percentage of wages to be paid going forward. The percentagde rate is commonly adjusted on an annual basis.Illinois Department of Employment Security Contact Information

The Federal Unemployment Tax Act is a federal law that imposes an unemployment tax on employers. The FUTA tax funds the federal government's oversight of each state's unemployment program. Only employers pay FUTA tax; there is no requirement for withholding amounts from employee wages. Employers must deposit the tax quarterly and file an annual form.

FUTA Tax is used to fund the administrative costs of the Illinois Unemployment Insurance program while Unemployment Tax is used solely for the payment of benefits to unemployed Illinois workers.

The current FUTA tax rate is 6%. FUTA tax only applies to the first $7,000 you pay to each employee in a calendar year. You will stop paying FUTA taxes on an employee's wages once you pay the employee more than $7,000. Currently, the largest FUTA amount you will have to pay is $420 per employee ($7,000 x 0.06).

If you have FUTA tax liabilities, you need to make quarterly deposits and file IRS Form 940.

All employers must now deposit FUTA taxes by using electronic funds transfer (EFT). Usually, EFT payments are made using the Electronic Federal Tax Payment System (EFTPS). EFTPS is a free service offered by the U.S. Department of the Treasury that allows you to pay federal taxes online or over the phone. When you request a new EIN and indicate you will have federal tax payments, you are automatically pre-enrolled in EFTPS. The IRS will notify you about the pre-enrollment and how you can activate the account. If you are not pre-enrolled, you can sign up directly on the EFTPS website or by calling the EFTPS at 800-555-4477.

All Illinois employers may be required to have Workers' Compensation Insurance even if they have only one employee. While there are exceptions, almost all Illinois employees who are injured on the job are eligible for Workers' Compensation Insurance benefits.

Insurance rates vary depending on the type of business being conducted, the carrier's rate and the employer's annual payroll. On average the current cost of an approved Workers' Compensation Insurance policy in the state of Illinois is approximately $0.00 per $100 in payroll.

An Illinois Employer who fails to obtain Workers' Compensatoin Insurance may be fined up to $500 for every day of noncompliance, with a minimum fine of $10,000. In addition. corporate officers can be held personally liable if the company fails to pay the penalty.
