Form ST-556 Information

              The Department of Revenue is in the
process of consolidating all taxes and
fees it administers into a single computer
system. In December of 2007, we brought
sales taxes fi led on ST-1 returns into the
new system; in September of 2009, vehicle
sales and use taxes will be added to this
system. This bulletin explains changes that
affect Form ST-556 fi lers.
What are the changes?
The biggest changes are:
The new tax system does accounting
on a period basis instead of on a
transaction basis. As illustrated later,
returns that are overpaid or underpaid
will be summarized by period (a period
is a date of delivery).
You will no longer be mailed a
Statement of Account each month.
Instead the detailed breakdown of
credits will be available on demand
as a Credit Activity Statement and the
detailed breakdown of liabilities will
be available on demand as a Detailed
Liability Statement. We illustrate these
documents and explain how to obtain
them later in this bulletin.
Other changes include:
Your Illinois Business Tax (IBT) number
is now referred to as your Account ID.

•
Your ST-556 and ST-1 are now
considered two separate accounts
although the Account ID (previously IBT
no.) will be used for both accounts.
Use of credit memoranda has changed.
Notices, bills, and statements have a
new look.
What has changed with my Illinois
Business Tax (IBT) number?
Your Illinois Business Tax number is now
referred to as your Account ID. For
ST-556 accounts, the number itself will not
change, just how we refer to it. You will
fi nd this number on your forms and on all
correspondence you receive. Continue using
your existing stock of Forms ST-556.
How are credit memoranda used?
The new system will automatically apply
an ST-556 credit memorandum to any
outstanding debt within your ST-556 account
before it is applied to your ST-1 account.
What changes can I expect on
correspondence?
Notices and bills have a new look and new
titles. Most are very similar to the ones you
recently may have received for your
Form ST-1.
