(1)
As used in this section, "GIS database" means the geographic information system database that the department of revenue owns and maintains, that meets the defined scope of work set forth in the request for solicitation, and is provided to vendors to determine the jurisdictions to which tax is owed and to calculate appropriate sales and use tax rates for individual addresses.
(2)
The department of revenue shall immediately notify vendors when the GIS database is online, tested, and verified by the department of revenue to be operational, supported, and available for use. Notification to vendors may be provided in any way that the department deems appropriate and must be accomplished within existing resources.
(3)
Any vendor that collects and remits sales tax to the department of revenue as provided by law, including any local sales or use tax pursuant to part 2 of title 29, may use the GIS database. Any vendor that directly uses the data contained in the GIS database, or uses data from a third-party database that is verified to use the most recent information provided by the GIS database, to determine the jurisdictions to which tax is owed is held harmless for any tax, charge, or fee liability to any taxing jurisdiction that otherwise would be due solely as a result of an error or omission in the GIS database data.
(3.5)
(a)
The general assembly finds and declares that:
(I)
The task force has overseen the implementation of an electronic sales and use tax simplification system, which is commonly known as "SUTS" and includes the GIS database, in furtherance of the general assembly's goal to address the complex and cumbersome nature of Colorado's unique state and local sales tax system, which is a matter of statewide concern;
(II)
SUTS and the GIS database are designed, among other things, to assist businesses operating in multiple taxing jurisdictions in Colorado by providing them with a single, reliable source of sales and use tax information for the state and local taxing jurisdictions, including any county, city and county, or municipality governed by a home rule charter;
(III)
While the sales and use tax bases and rates of the state and local taxing jurisdictions and the jurisdictional boundaries of such local taxing jurisdictions are subject to change over time, SUTS was specifically designed in anticipation of such changes pursuant to section 39-26-802.5 (1)(c)(IV) and (1)(c)(V);
(IV)
It is a matter of statewide concern to ensure that SUTS, including the GIS database, continues to serve and evolve as an effective simplification tool upon which businesses can rely in navigating Colorado's unique and complex state and local sales tax system;
(V)
Improving SUTS in this manner will decrease filing complexity, make audits of retailers more uniform for all state and local taxing jurisdictions, help streamline and reduce administrative burdens, and, consequently, encourage more businesses to begin or continue to operate across multiple taxing jurisdictions across this state; and
(VI)
Any business that uses the data collected in SUTS, inclusive of data collected in the GIS database, to determine the local taxing jurisdictions to which tax is owed should be held harmless in an audit by the state or any local taxing jurisdiction, including any county, city and county, or municipality governed by a home rule charter for any tax, charge, or fee liability to any local taxing jurisdiction that would be due solely as a result of an error or omission in the SUTS or GIS database data.
(b)
As used in this subsection (3.5), unless the context otherwise requires:
(I)
"Electronic sales and use tax simplification system" means the electronic system described in section 39-26-802.7 for the collection and remittance of sales and use taxes.
(II)
"Local taxing jurisdiction" means a city, town, municipality, county, special district, or authority authorized to levy a sales or use tax pursuant to title 24, 25, 29, 30, 31, 32, 37, 42, or 43, and any county, city and county, or municipality governed by a home rule charter that uses the electronic sales and use tax simplification system.
(III)
"Tax rate" means the general sales or use tax rate imposed by a local taxing jurisdiction, without regard to any local sales or use tax exemption or special tax rate.
(c)
(I)
Any vendor that uses the data contained in the GIS database to determine the tax rate and the local taxing jurisdictions to which sales or use tax is owed is held harmless in an audit by any local taxing jurisdiction for any tax, charge, or fee liability to the local taxing jurisdiction that otherwise would be due solely as a result of an error or omission in the GIS database data.
(II)
To be held harmless pursuant to subsection (3.5)(c)(I) of this section, a vendor must collect, retain, and produce upon request documentation reasonably sufficient to demonstrate the vendor's proper use of and reliance on the GIS database data to determine the tax rate and local taxing jurisdiction to which tax was owed.
(III)
A vendor that queries the GIS database using an incomplete or erroneous address shall not be held harmless pursuant to subsection (3.5)(c)(I) of this section for the failure to pay any tax, charge, or fee liability to a local taxing jurisdiction.
(d)
The department of revenue, or its third-party contractor, shall update the data contained in the GIS database, including jurisdictional boundaries and tax rates, within thirty days of the receipt by the department of revenue of updated or corrected data from a local taxing jurisdiction, and shall maintain the GIS database data in an accurate condition in accordance with subsection (4) of this section. The department shall provide a reasonably convenient method for local taxing jurisdictions to inform the department of any errors in the GIS database data.
(4)
(a)
The department of revenue shall ensure that the GIS database data is at least ninety-five percent accurate based on a statistically valid sample of addresses from the database, or based on another acceptable method of proving accuracy.
(b)
The department of revenue shall update the GIS database with respect to any geographic boundary changes described in section 29-2-205 (4) within thirty days of receipt of the written notice described in section 29-2-205 (1). If the department of revenue does not timely receive the notice described in section 29-2-205 (1), then the department shall update the GIS database as soon as possible after receiving the geographic boundary change information.
(5)
The executive director of the department of revenue shall promulgate rules for the administration of this section. Such rules must be promulgated in accordance with article
4
