86 Ill. Adm. Code 130.805
Minimum Requirements for Recordkeeping
Section 130
Section 130.805
Minimum Requirements for Recordkeeping
a)Â Â Â Â Â Â Â Â In General. A taxpayer shall maintain all records that are
necessary to
determine
the correct tax
liability under the
Retailers' Occupation Tax
Act
("Act") [35 ILCS 120]
. All
required records must be made available
upon
request by the Department. Where a taxpayer's business consists of the sale of
tangible personal property at retail, the following records will be deemed by
the Department to constitute a minimum for the purposes of the Act:
1)
Cash register tapes, point-of-sale
system printouts, and other data used to prepare returns, whether monthly,
quarterly, or yearly depending on the taxpayer's filing status. The monthly,
quarterly, or yearly records shall have the capability to detail each
transaction with sufficient "transaction-level records."Â For
purposes of this Section, "transaction-level records" means, at a
minimum, the date of the transaction, invoice or transaction number,
description of the items sold, the selling price, and the amount of tax or
proper exempt status.
2)        A record of the amount of merchandise purchased. To fulfill
this requirement, copies of all vendors' invoices and taxpayers' copies of
purchase orders must be retained serially and in sequence as to date.
3)Â Â Â Â Â Â Â Â A true and complete inventory of the value of stock on hand
taken at least once each year.
4)Â Â Â Â Â Â Â Â Bank statements for all accounts associated with
the business.
5)Â Â Â Â Â Â Â Â Federal income tax returns, including all
schedules, and all working papers used to prepare the federal income tax
returns, including all Form 1099-Ks.
6)Â Â Â Â Â Â Â Â Sales tax returns, including all schedules and
working papers used to prepare the sales tax returns.
7)Â Â Â Â Â Â Â Â Monthly statements supporting all Form 1099-Ks
received (e.g., from marketplace facilitators, payment processors).
8)Â Â Â Â Â Â Â Â Log of all cash disbursements to vendors,
employees, and others.
9)Â Â Â Â Â Â Â Â Documentation for exempt and other non-taxable
receipts including such documentation as the name of the exempt entity,
Illinois Account ID number, resale certificate, or records relating to sales in
interstate commerce. See 86 Ill. Adm. Code 130.120, 130.1405, and 130.2081(c).
10)Â Â Â Â Â Â For sales requiring delivery, information
detailing the purchaser's name, street address, city, state, and ZIP code for
each sales transaction, and if shipped to an address other than the
purchaser's, the name, street address, city, state, and ZIP code where delivery
is made.
11)Â Â Â Â Â Â Any records identified by the Department from a
prior audit that the taxpayer was instructed to keep.
12)Â Â Â Â Â Â The Department reserves the right to
request any records necessary to complete verification, keeping in mind changes
in technology and the retailer's specific business.
b)Â Â Â Â Â Â Â Â Records prepared by Automated Data Processing Systems
("ADP"). When an ADP tax accounting system is used to maintain all
or part of a taxpayer's accounting or financial records, such ADP system must
include a method of producing legible and readable records which will provide
the necessary information for verifying tax liability. If a taxpayer retains
records required to be retained under Section 130.801 of this Part, in both
machine-sensible and hard-copy formats, the taxpayer shall make the records
available to the Department in machine-sensible format upon request of the
Department in accordance with subsection (b)(5) of this Section. ADP
accounting systems encompass all types of data processing systems including,
but not limited to, mainframe computer systems, stand-alone, or networked
microcomputer systems, Database Management Systems ("DBMS"), and
systems using Electronic Data Interchange ("EDI") technology.
1)Â Â Â Â Â Â Â Â Definitions
A)Â Â Â Â Â Â Â "Database Management System" or "DBMS"
means a software system that creates, controls, relates, retrieves, and
provides accessibility to data stored in a database.
B)Â Â Â Â Â Â Â "Electronic Data Interchange" or "EDI
technology" means the computer-to-computer exchange of business
transactions in a standardized structured electronic format.
C)Â Â Â Â Â Â Â "Machine-sensible record" means a collection of
related information in an electronic format. Machine-sensible records
include, but are not limited to, data created by
point-of-sale ("POS") systems or accounting software, Excel
documents, and searchable portable document format ("PDF").Â
Machine-sensible records
do not include hard-copy records that are
created or recorded on paper or stored in or by an imaging system such as
storage-only imaging systems.
D)Â Â Â Â Â Â Â "Storage-only imaging systems" means a system of
computer hardware and software that provides for the storage, retention, and
retrieval of documents originally created on paper
,
including but not limited to, static PDFs or joint photographic experts group
("JPEG")
. It does not include any system, or part of a
system, that manipulates or processes any information or data contained on the
document in any manner other than to reproduce the document in hard-copy or as
an optical image.
E)Â Â Â Â Â Â Â "Hard-copy" means any documents, records, reports, or
other data printed on paper.
F)Â Â Â Â Â Â Â Â "Point-of-sale
("POS") systems" means a system of computer hardware, software,
or both that manages customer purchases, accepts payment, and provides
receipts. A POS is also how a retailer and a customer record a transaction.
2)Â Â Â Â Â Â Â Â Recordkeeping Requirements - Machine-Sensible Records
A)Â Â Â Â Â Â Â General Requirements
i)Â Â Â Â Â Â Â Â Â Machine-sensible records used to establish tax compliance
shall be retained by the taxpayer. The retained records shall provide
sufficient information to establish matters required to be shown by a taxpayer
in any tax or information returns. The machine-sensible records shall contain
sufficient "transaction-level
records" as
defined in subsection (a)(1)
so that the details and the source
documents underlying the machine-sensible records can be identified and made
available to the Department upon request.
ii)Â Â Â Â Â Â Â Â The retained records should reconcile to the books and to the
tax return by establishing the relationship (e.g., the audit trail) between the
total of the amounts in the retained records to the totals in the books and to
the tax return.
iii)       The retained records must be capable of being processed. For
purposes of this Section, "capable of being processed" means to be
able to retrieve, manipulate, print hard-copy, or produce other output. This
term does not encompass any requirement that the program or system that created
the computer data be available to process the data unless the process is
essential to a tax-related computation.
iv)Â Â Â Â Â Â Â Taxpayers are not required to construct machine-sensible
records other than those created in the ordinary course of business. A
taxpayer who does not create the electronic equivalent of a traditional paper
document in the ordinary course of business is not required to construct such a
record for tax purposes.
v)Â Â Â Â Â Â Â Â All records required to be retained under this Section shall
be preserved unless the Department has provided in writing that the records are
no longer required as explained in Section 130.825 of this Part.
B)Â Â Â Â Â Â Â Electronic Data Interchange
("EDI")
i)Â Â Â Â Â Â Â Â Â Where a taxpayer uses
EDI
processes and technology, the level of record detail, in combination with other
records related to the transaction,
must satisfy the
minimum "transaction-level records" requirement as detailed in
subsection (a)(1)
.
Taxpayer may use codes
to identify some or all of the data elements,
as long
as
the taxpayer provides a method that allows the Department to
interpret the coded information.
ii)Â Â Â Â Â Â Â Â The taxpayer may capture the information necessary to satisfy
subsection (b)(2)(B)(i) at any level within the accounting system and need not
retain the original EDI transaction records provided the audit trail,
authenticity, and integrity of the retained records can be established.
EXAMPLE:Â A
taxpayer using
EDI
technology receives electronic invoices from its suppliers. The taxpayer
decides to retain the invoice data from completed and verified EDI transactions
in its accounts payable system rather than to retain the EDI transactions
themselves.
Neither
the EDI transaction nor
the accounts payable system captures information from the invoice pertaining to
the product description or the vendor name (i.e., they contain only codes for
that information). Therefore, the taxpayer must also retain other records,
such as its vendor master file and product code description lists, and make
them available to the Department.
If the taxpayer
does this
, the taxpayer need not retain its EDI transaction for tax
purposes.
C)       Electronic Data Processing Systems Requirements. The
requirements for an electronic data processing accounting system are similar to
that of a manual accounting system, in that an adequately designed accounting
system should incorporate methods and records that will satisfy the
requirements of this Section.
3)Â Â Â Â Â Â Â Â Recordkeeping Requirements - ADP Systems Documentation
A)Â Â Â Â Â Â Â Upon the request of the Department, the taxpayer shall provide
a description of the business process that created the retained records. Such
description shall include the relationship between the records and the tax
documents prepared by the taxpayer and the measures employed to ensure the
authenticity and integrity of the records.
B)Â Â Â Â Â Â Â The taxpayer shall be capable of demonstrating:
i)Â Â Â Â Â Â Â Â Â the functions being performed as they relate to the flow of
data through the system;
ii)Â Â Â Â Â Â Â Â the internal controls used to ensure accurate and reliable
processing; and
iii)Â Â Â Â Â Â Â the internal controls used to prevent the unauthorized
addition, alteration, or deletion of retained records.
C)Â Â Â Â Â Â Â The following specific documentation is required for
machine-sensible records pursuant to this Section:
i)Â Â Â Â Â Â Â Â Â record formats and layouts;
ii)Â Â Â Â Â Â Â Â field definitions, including the meaning of all
"codes" used to represent information;
iii)Â Â Â Â Â Â Â file descriptions (e.g., data set name); and
iv)Â Â Â Â Â Â Â detailed charts of accounts and account descriptions.
D)Â Â Â Â Â Â Â Any changes to the items specified in subsections (b)(3)(B) and
(C) above, together with their effective dates, shall be documented and made
available to the Department upon request.
4)Â Â Â Â Â Â Â Â Machine-Sensible Records Maintenance Requirements
A)Â Â Â Â Â Â Â The establishment of records management practices is solely at
the discretion of the taxpayer, who ultimately bears the burden of producing
records capable of being processed at the time of an examination by the
Department. The Department recommends but does not require that taxpayers
refer to the National Archives and Record Administration's ("NARA")
standards for guidance on the maintenance and storage of electronic records.
B)Â Â Â Â Â Â Â In establishing records management practices, taxpayers should
consider
the following to maintain the integrity of
the records:
the labeling of records, the security of the storage
environment, the creation of back-up copies and their storage location, and the
use of periodic testing.
C)Â Â Â Â Â Â Â The NARA standards may be found at 36 CFR 1234, July 1, 1995
edition.
D)Â Â Â Â Â Â Â The taxpayer's computer hardware or software shall accommodate
the processing of or the extraction and conversion of retained machine-sensible
records.
5)        Access to Machine-Sensible Records. The manner in which the
Department is provided access to machine-sensible records as required in
subsection (b) of this Section and Section 130.801(d) of this Part may be
satisfied through a variety of means that shall
,
after consultation with the taxpayer,
take into account the taxpayer's
individual
circumstances. Such access will be provided
in one or more of the following manners:
A)       A taxpayer may provide the Department copies of the machine‑sensible
records for use on the Department's equipment;
B)Â Â Â Â Â Â Â The taxpayer may arrange to provide the Department with the
hardware, software, and personnel resources necessary to access and process the
machine-sensible records;
C)Â Â Â Â Â Â Â The taxpayer may arrange for a third party to provide the
hardware, software, and personnel resources necessary to access and process the
machine-sensible records;
D)Â Â Â Â Â Â Â The taxpayer may convert machine-sensible records to a standard
electronic
record format specified by the
Department. These records may be processed on the Department's equipment or at
the taxpayer's location; or
E)Â Â Â Â Â Â Â The taxpayer and the Department may agree on other means of
providing access to the machine-sensible records.
6)Â Â Â Â Â Â Â Â Taxpayer Responsibility and Discretionary Authority
A)
Taxpayers are responsible for
determining
which of their machine-sensible records must be retained and
which records may be discarded. These determinations require a consideration
of all the facts and circumstances, including whether duplicated or redundant
records exist.
B)Â Â Â Â Â Â Â In general, taxpayers should retain the machine-sensible
records that are the most direct evidence of the transactions and have
discretion to discard duplicated records and redundant information. In
exercising this discretion, the taxpayer should generally retain those records
that best facilitate the retrieval and processing of the data during an audit.Â
For example, departmental records stored in departmental data files that are
duplicated in a central system could be discarded provided that all required
information in the departmental records is contained in the central system and
the requirements of this Section are met. Similarly, daily or weekly data
files could be discarded provided that appropriate monthly, quarterly, or
annual data files with the ability to access appropriate transaction-level
records are available.
C)Â Â Â Â Â Â Â In conjunction with meeting the requirements of this Section, a
taxpayer may create files solely for the use of the Department. For example,
if a database management system is used, it is consistent with this Section for
the taxpayer to create and retain a file that contains the transaction-level
detail from the database management system and that meets the requirements of
the Section. The taxpayer should document the process that created the
separate file to show the relationship between that file and the original
records.
D)Â Â Â Â Â Â Â A taxpayer may contract with a third party to provide custodial
or management services of the records. Such a contract shall not relieve the
taxpayer of its responsibilities under this Section.
c)        Alternative Storage Media. For purposes of storage and
retention, taxpayers may convert hard-copy documents received or produced in
the normal course of business and required to be retained under this Section to
storage-only imaging systems
, such as static PDFs or
JPEGs,
and may discard the original hard-copy documents, provided the
conditions of this Section are met. These records are not a substitute for
machine-sensible records described in subsection (b) of this Section.Â
Documents which may be stored on these media include, but are not limited to,
general books of account, journals, voucher registers, general and subsidiary
ledgers and supporting records of details, such as sales invoices, purchase
invoices, exemption certificates, and credit memoranda.
Storage-only
imaging systems shall meet the
following requirements:
1)Â Â Â Â Â Â Â Â Documentation establishing the procedures for converting the
hard-copy documents to storage-only imaging systems must be maintained and made
available upon request. Such documentation shall, at a minimum, contain
sufficient description to allow an original document to be followed through the
conversion system as well as internal procedures established for inspection and
quality assurance.
2)Â Â Â Â Â Â Â Â Procedures must be established for the effective
identification, processing, storage, and preservation of the stored documents
and for making them available for the periods they are required to be retained
under the Retailers' Occupation Tax Act [35 ILCS 120].
3)Â Â Â Â Â Â Â Â All data stored on storage-only imaging systems must be
maintained and arranged in a manner that permits the location of any particular
record.
4)
Storage-only
imaging systems
records must be indexed, cross-referenced, and labeled to show beginning and
ending numbers or beginning and ending alphabetical listing of documents
included, and must be systematically filed to permit the immediate location of
any particular record. A posting reference must be on each document and a
control log or catalog of such documents must be maintained.
5)Â Â Â Â Â Â Â Â Upon request of the Department, a taxpayer must provide
facilities and equipment, in good working order, for reading, locating, and
reproducing any documents maintained on storage-only imaging systems.
6)Â Â Â Â Â Â Â Â When displayed on such equipment or reproduced on paper, the
documents must exhibit a high degree of legibility and readability. For this
purpose, legibility is defined as the quality of a letter or numeral that
enables the observer to identify it positively and quickly to the exclusion of
all other letters or numerals. Readability is defined as the quality of a
group of letters or numerals being recognized as words or complete numbers.
7)Â Â Â Â Â Â Â Â There must be no substantial evidence that the storage-only
imaging systems lack authenticity or integrity.
d)Â Â Â Â Â Â Â Â Effect on Hard-Copy Recordkeeping Requirements
1)Â Â Â Â Â Â Â Â Except as otherwise provided, the provisions of this Section
do not relieve taxpayers of the responsibility to retain hard-copy records that
are created or received in the ordinary course of business as required by
existing law and regulations. Hard-copy records may be retained on a
recordkeeping medium provided in subsection (c).
2)Â Â Â Â Â Â Â Â If hard-copy records are not produced or received or required
to be produced or received in the ordinary course of transacting business
(i.e., when the taxpayer uses electronic data interchange technology), such
hard-copy records need not be created.
3)Â Â Â Â Â Â Â Â Unless hard-copy records are required to be provided or
received, hard‑copy records generated at the time of a transaction need
not be retained if all the details relating to the transaction are subsequently
received by the taxpayer in an EDI transaction and are retained by the taxpayer
in accordance with this Section.
4)Â Â Â Â Â Â Â Â Hard-copy records generated at the time of a transaction using
a credit or debit card must be retained unless all the details necessary to
determine correct tax liability relating to the transaction are subsequently
received and retained by the taxpayer in accordance with this Section. Such
details include, but may not be limited to, those listed in subsection
(b)(2)(B).
5)Â Â Â Â Â Â Â Â Computer printouts that are created for validation, control,
or other temporary purposes need not be retained.
6)Â Â Â Â Â Â Â Â Nothing in this Section shall prevent the Department from
requesting hard-copy printouts of retained machine-sensible records. These
requests may be made either at the time of an examination or in conjunction
with the testing described in Section 130.825 of this Part.
