Is software sold with a click-through license taxable in Illinois, and does it matter whether the software is downloaded or purely cloud-based?
It depends on delivery and license terms: software delivered purely through the cloud with nothing downloaded is generally not taxable (it's a nontaxable service), but software that includes any local…
Is an out-of-state municipality's tax-exempt certificate enough to avoid Illinois telecommunications tax on a data-center internet connection located in Illinois?
No. Illinois's telecommunications-tax exemption for 'sales at retail' is limited to the federal government, the State government, and Illinois state universities -- it does NOT extend to local governm…
Is a telephone cooperative's dark fiber lease subject to Illinois's Telecommunications Excise Tax or sales tax, and is its wholesale local loop service exempt?
Dark fiber (unlit fiber optic cable carrying no signal) is NOT subject to the Telecommunications Excise Tax, because it doesn't transmit any information. Buried dark fiber cable is treated as real pro…
What are all the different taxes and fees listed on an Illinois landline phone bill, and who collects each one?
A landline bill in Illinois can show up to six separate items: a $1.50-per-connection 911 surcharge, a 0.1% Public Utilities Fund tax, a 0.5% Telecommunications Infrastructure Maintenance Fee, a Unive…
We provide cloud-based data-processing services that translate and relay medical lab test results to physician practices and patients (some of whom can also download free mobile apps), and we've recently crossed Illinois's $100,000 economic-nexus threshold -- do any of our fees trigger Illinois Retailers' Occupation Tax, Use Tax, Service Occupation Tax, Service Use Tax, or the Telecommunications Excise Tax, and do we have to register and collect?
No on all counts, on these specific facts. The Department ruled the company's Monthly Data Processing Fees and Initial Setup Fees are not taxable because the company acts as a "serviceman" providing t…
Does Illinois sales tax, service occupation tax, or telecommunications excise tax apply to cloud-based practice-management software sold to healthcare providers?
The Department did not issue a yes/no ruling on this taxpayer's specific facts (that requires a binding Private Letter Ruling), but it confirmed the general framework: canned computer software is taxa…
Does Illinois's Telecommunications Excise Tax apply to dark fiber leased under an Indefeasible Right of Use (IRU) or to a non-indefeasible right to use fiber strands between two locations?
No. Dark fiber -- fiber-optic strands with no light or signal running through them -- carries no messages or information, so it doesn't meet the statutory definition of "telecommunications" in 35 ILCS…
Is Voice Over Internet Protocol (VoIP) voice service subject to Illinois's Telecommunications Excise Tax and the Simplified Municipal Telecommunications Tax?
Yes. Illinois taxes VoIP voice service the same as any other telecommunications — both the statewide Telecommunications Excise Tax and, where a municipality has adopted it, the Simplified Municipal Te…
Does Illinois sales tax apply to a records-management company's document storage, shredding, scanning, software, and related service fees?
Generally, no. The Department confirmed that if a transaction does not involve transferring tangible personal property to the customer, no Retailers' Occupation Tax, Use Tax, Service Occupation Tax, o…
Does a company that resells hosted phone system licenses have to collect and remit Illinois telecommunications tax or sales tax on those licenses?
It depends on what's actually being resold: hosted telecommunications service is generally subject to the 7% Telecommunications Excise Tax unless the reseller holds an active Illinois resale number, w…
Does Illinois Telecommunications Excise Tax or sales tax apply to a fleet-telematics company's purchased data plans and its monthly customer fee?
No to both questions. The Department concluded that the company's purchased cellular data connectivity qualifies as exempt 'internet access' under the federal Internet Tax Freedom Act, so it is not su…
Does Illinois's Telecommunications Excise Tax exemption for 'State governments' cover sales to OTHER states' governments (and their agencies), not just Illinois's own government -- and can a taxpayer get a binding ruling on that?
Yes -- the state-government exemption in the Telecommunications Excise Tax Act applies to Illinois and all 49 other states, and to their executive, legislative, and judicial agencies and instrumentali…
Our company sells an enhanced communications-platform product to Illinois customers, and separately some businesses offer software as a service or resell conferencing/telecom services -- when is computer software a taxable retail sale versus a non-taxable license, when does SaaS/cloud delivery escape sales tax, and when does audio-conferencing trigger the Telecommunications Excise Tax?
The Department did NOT classify the taxpayer's own PRODUCT -- it first declined to issue the binding Private Letter Ruling the taxpayer requested, citing "the lack of information regarding the product…
IDOC's inmates fund 'offender debit accounts' by paying money at prison commissaries, and IDOC forwards that money to its telecom vendor to pay for phone service. Does that arrangement make IDOC a 'reseller' of telecommunications services -- entitled to give the vendor a certificate of resale -- and does a separate statute capping per-minute inmate calling charges relieve the vendor of its own Telecommunications Excise Tax liability?
No on both counts. IDOC is not acting as a retailer or reseller of telecommunications services merely because it collects money from inmates at commissaries and forwards it to the telecom provider, so…
My state government agency buys telecom services used by our staff in Illinois -- does Illinois's telecommunications excise tax exemption for 'state governments' cover MY state, or only Illinois's own government?
Yes -- the Illinois Department of Revenue confirmed that the Telecommunications Excise Tax Act's exemption for 'State governments' is not limited to Illinois's own government; it covers state governme…
Is Illinois Telecommunications Excise Tax imposed on fire alarm monitoring services?
It depends on how the fire alarm company bills for the phone/transmission line. Fire alarm services provided by telecommunications retailers, or by other retailers that resell telephone services, ARE …
If I separately state equipment rental or lease charges from VoIP service charges on the bill, do I still owe Illinois Telecommunications Excise Tax on the equipment charges?
No, equipment rental or lease charges are excluded from the Illinois Telecommunications Excise Tax as long as they are disaggregated and separately stated from the telecommunications service charges i…
When did Illinois tax a telecommunications late fee, and could the Department decide whether the fee on this customer's bill was taxable?
A late fee separately stated from telecommunications charges was not subject to Telecommunications Excise Tax, while a fee not separately stated was taxable. For sales tax, a true finance charge was e…
Were urgent-response medical monitoring, wireless data, and ordinary cell-phone services subject to Illinois Telecommunications Excise Tax?
IDOR would not confirm the company's specific treatment in a nonbinding GIL. It said ordinary mobile phone service incurred Telecommunications Excise Tax, while wireless data plans generally fell unde…
How did Illinois tax a cloud-based hotel texting service and separately charged printer usage?
A service transferring no tangible property generally avoided retail, use, and service taxes, and online text or data was intangible. IDOR did not expressly classify the texting service for telecommun…
Did Illinois Telecommunications Excise Tax apply to bandwidth an Internet provider bought to supply Internet access?
To the extent the provider bought and supplied the bandwidth so customers could connect to the Internet or access online content and services, the 2015 letter treated it as Internet access covered by …

How did Illinois tax videoconference room, bridging, and ISDN charges?
IDOR did not specifically classify the described bridging or ISDN services. A room or service transferring no tangible property avoided retail, use, and service taxes. Actual telecommunications charge…
Did Illinois's Telecommunications Excise Tax exempt all interstate calls?
No. The interstate-commerce entry was not a blanket deduction. Illinois taxed an interstate call originating or received in Illinois when the charge went to an Illinois service address, subject only t…
How did Illinois's 2014 Telecommunications Excise Tax guidance treat Internet access, lit fiber, and dark-fiber leases?
During the federal Internet-access moratorium then ending November 1, 2014, qualifying Internet access and lit fiber used by ISPs to provide it generally were not taxable. Other telecom services, incl…
Did a cloud collaboration provider owe Illinois Telecommunications Excise Tax when customers used their own internet and telecom connections?
Generally no, if customers accessed the cloud applications through internet or telecommunications connections they bought from third parties. In that situation the cloud provider was not itself provid…
Are one-time customer account setup fees subject to Illinois Telecommunications Excise Tax?
Generally yes. IDOR said one-time account setup fees were necessary for and directly related to providing telecommunications, so they were included in gross charges subject to the 7% Illinois Telecomm…
Did prepaid home-phone packages qualify as prepaid telephone calling arrangements taxed as tangible personal property rather than telecommunications?
Generally yes. A package paid in advance that enables calls through an access or authorization code and stops service when the purchased amount is consumed generally qualifies as a prepaid telephone c…
Were charges for web-based meetings, webinars, and training subject to Illinois Telecommunications Excise Tax when users supplied their own connectivity?

What amount was subject to Illinois sales tax when a cellular phone was sold below cost with a service contract?
IDOR did not classify the retailer's exact bundle on the limited facts. It said a sold phone was tangible personal property and Retailers' Occupation Tax was measured by the gross receipts actually re…
Were subscriber line charges and primary interexchange carrier charges subject to Illinois Telecommunications Excise Tax?
Yes. Subscriber line charges were included in taxable telecommunications gross charges because they recovered the local exchange company's cost of providing service. Primary interexchange carrier char…
Which Illinois taxes and 9-1-1 surcharge applied when a wireless retailer accepted payments for prepaid or subscription plans?
A true prepaid calling arrangement—service bought in advance and exhausted in known units or dollars—was tangible personal property subject to Retailers' Occupation Tax. A payment credited to an exist…

Did Illinois's prepaid wireless 9-1-1 surcharge apply to every prepaid calling card reported for sales tax, including an international access-code card?

How did Illinois tax media postproduction, film or videotape duplication, and electronic transmission services?
Pure services without a transfer of tangible personal property were outside Retailers' Occupation, Use, Service Occupation, and Service Use Tax. When film, videotape, or other tangible media was trans…
Did unreimbursed loyalty-point and coupon discounts reduce Illinois taxable receipts for retail goods and wireless telecommunications?

Did Illinois's rolling-stock exemption cover cellular data charges for GPS tracking on interstate trucks?

Did Illinois decide whether hosted call-automation software, phone-number charges, and a regulatory recovery fee were taxable telecommunications?

Should an Illinois telecommunications carrier charge Telecommunications Excise Tax to a consular official who holds a federal diplomatic tax exemption?
