What payment methods are available if I have an amount due on my individual income tax return?
You have three options to pay the amount you owe. You may pay by:
* Web Pay (electronic payment taken from your checking or savings account);
* credit card (Visa, MasterCard, Discover, or American Express);
* or check or money order.
If you choose to mail a check or money order, mail your payment to:
Illinois Department of Revenue
Springfield IL 62726-0001
Make your check payable to the Illinois Department of Revenue. Write your
Social Security number, your spouse’s Social Security number if filing
jointly, and the tax year in the lower left-hand corner of your payment.
Who must file the IL-1120?
You must file Form IL-1120, Illinois Corporation Income and Replacement Tax
Return, if you are a corporation that
* has net income or loss as defined under the Illinois Income Tax Act (IITA);
or
* is qualified to do business in the state of Illinois and is required to file
a federal income tax return (regardless of net income or loss).
Are there any electronic payment methods for business income tax?
The only electronic method for businesses is the Electronic Funds Transfer
(EFT) for certain payments. The EFT is an electronic payment method that you
use to pay your tax liabilities. Instead of writing a check for the amount of
tax due, you instruct your financial institution to transfer the funds from
your account to ours. We then apply the transferred amount to your liability.
Businesses may pay their IL-1120-ES and IL-505-B with this method.
Who is required to register with the Illinois Department of Revenue?
You may be required to register with us if your business is a sole
proprietorship (individual or husband/wife), an exempt organization, or a
government agency, and you are liable for reporting Sales and/or Use Tax, sale
for resale, or withholding for Illinois employees. Please refer to the
Illinois Admin. Code, Section 130.701. It is unlawful for any person to
engage in business of selling tangible personal property at retail in Illinois
without a Certificate of Registration from the department. "Persons" include
many types of businesses, including, but not limited to, sole proprietorships,
corporations, limited liability companies, partnerships, and the like.
You may be required to register with us if your business is a partnership, a
small business corporation, or a corporation and you conduct business in
Illinois or with Illinois customers.
If I send you a payment, what address should I use?
You should mail the payment to the address shown on the notice or bill you
received from us. Generally the address is located on the payment voucher of
the notice or bill. If you do not have a notice or bill you can mail the
payment to
Illinois Department of Revenue
PO Box 19044
Springfield, IL 62794-9044.
