35 ILCS 120/2
The imposition of the tax under this Act on persons engaged in the business of leasing tangible personal property applies to leases in effect, entered into, or renewed on or after January 1, 2025. In the case of leases, except as otherwise provided in this Act, the lessor must remit, for each tax return period, only the tax applicable to that part of the selling price actually received during such tax return period.
The inclusion of leases in the tax imposed under this Act by this amendatory Act of the 103rd General Assembly does not, however, extend to motor vehicles, watercraft, aircraft, and semitrailers, as defined in Section 1-187 of the Illinois Vehicle Code, that are required to be registered with an agency of this State. The taxation of these items shall continue in effect as prior to the effective date of the changes made to this Section by this amendatory Act of the 103rd General Assembly (i.e., dealers owe retailers' occupation tax, lessors owe use tax, and lessees are not subject to retailers' occupation or use tax).
Sales of (1) electricity delivered to customers by wire; (2) natural or artificial gas that is delivered to customers through pipes, pipelines, or mains; and (3) water that is delivered to customers through pipes, pipelines, or mains are not subject to tax under this Act. The provisions of this amendatory Act of the 98th General Assembly are declaratory of existing law as to the meaning and scope of this Act.
Remote retailers that meet or exceed the threshold in either paragraph (1) or (2) above shall be liable for all applicable State retailers' and locally imposed retailers' occupation taxes administered by the Department on all retail sales to Illinois purchasers.
The remote retailer shall determine on a quarterly basis, ending on the last day of March, June, September, and December, whether he or she meets the criteria of either paragraph (1) or (2) of this subsection for the preceding 12-month period. If the retailer meets the criteria of either paragraph (1) or (2) for a 12-month period, he or she is considered a retailer maintaining a place of business in this State and is required to collect and remit the tax imposed under this Act and all retailers' occupation tax imposed by local taxing jurisdictions in Illinois, provided such local taxes are administered by the Department, and to file all applicable returns for one year. At the end of that one-year period, the retailer shall determine whether the retailer met the criteria of either paragraph (1) or (2) for the preceding 12-month period. If the retailer met the criteria in either paragraph (1) or (2) for the preceding 12-month period, he or she is considered a retailer maintaining a place of business in this State and is required to collect and remit all applicable State and local retailers' occupation taxes and file returns for the subsequent year. If, at the end of a one-year period, a retailer that was required to collect and remit the tax imposed under this Act determines that he or she did not meet the criteria in either paragraph (1) or (2) during the preceding 12-month period, then the retailer shall subsequently determine on a quarterly basis, ending on the last day of March, June, September, and December, whether he or she meets the criteria of either paragraph (1) or (2) for the preceding 12-month period.
A marketplace facilitator who meets either paragraph (1) or (2) of this subsection is required to remit the applicable State retailers' occupation taxes under this Act and local retailers' occupation taxes administered by the Department on all taxable sales of tangible personal property made by the marketplace facilitator or facilitated for marketplace sellers to customers in this State. A marketplace facilitator selling or facilitating the sale of tangible personal property to customers in this State is subject to all applicable procedures and requirements of this Act.
The marketplace facilitator shall determine on a quarterly basis, ending on the last day of March, June, September, and December, whether he or she meets the criteria of either paragraph (1) or (2) of this subsection for the preceding 12-month period. If the marketplace facilitator meets the criteria of either paragraph (1) or (2) for a 12-month period, he or she is considered a retailer maintaining a place of business in this State and is required to remit the tax imposed under this Act and all retailers' occupation tax imposed by local taxing jurisdictions in Illinois, provided such local taxes are administered by the Department, and to file all applicable returns for one year. At the end of that one-year period, the marketplace facilitator shall determine whether it met the criteria of either paragraph (1) or (2) for the preceding 12-month period. If the marketplace facilitator met the criteria in either paragraph (1) or (2) for the preceding 12-month period, it is considered a retailer maintaining a place of business in this State and is required to collect and remit all applicable State and local retailers' occupation taxes and file returns for the subsequent year. If at the end of a one-year period a marketplace facilitator that was required to collect and remit the tax imposed under this Act determines that he or she did not meet the criteria in either paragraph (1) or (2) during the preceding 12-month period, the marketplace facilitator shall subsequently determine on a quarterly basis, ending on the last day of March, June, September, and December, whether he or she meets the criteria of either paragraph (1) or (2) for the preceding 12-month period.
A marketplace facilitator shall be entitled to any credits, deductions, or adjustments to the sales price otherwise provided to the marketplace seller, in addition to any such adjustments provided directly to the marketplace facilitator. This Section pertains to, but is not limited to, adjustments such as discounts, coupons, and rebates. In addition, a marketplace facilitator shall be entitled to the retailers' discount provided in Section 3 of the Retailers' Occupation Tax Act on all marketplace sales, and the marketplace seller shall not include sales made through a marketplace facilitator when computing any retailers' discount on remaining sales. Marketplace facilitators shall report and remit the applicable State and local retailers' occupation taxes on sales facilitated for marketplace sellers separately from any sales or use tax collected on taxable retail sales made directly by the marketplace facilitator or its affiliates.
The marketplace facilitator is liable for the remittance of all applicable State retailers' occupation taxes under this Act and local retailers' occupation taxes administered by the Department on sales through the marketplace and is subject to audit on all such sales. The Department shall not audit marketplace sellers for their marketplace sales where a marketplace facilitator remitted the applicable State and local retailers' occupation taxes unless the marketplace facilitator seeks relief as a result of incorrect information provided to the marketplace facilitator by a marketplace seller as set forth in this Section. The marketplace facilitator shall not be held liable for tax on any sales made by a marketplace seller that take place outside of the marketplace and which are not a part of any agreement between a marketplace facilitator and a marketplace seller. In addition, marketplace facilitators shall not be held liable to State and local governments of Illinois for having charged and remitted an incorrect amount of State and local retailers' occupation tax if, at the time of the sale, the tax is computed based on erroneous data provided by the State in database files on tax rates, boundaries, or taxing jurisdictions or incorrect information provided to the marketplace facilitator by the marketplace seller.
