Telco Filing Deadline Approaching – March 1

February 13, 2023

To: Telecommunications

The Wisconsin Department of Revenue (DOR) would like to remind you of the upcoming March 1, 2023 Telco filing deadline.

File electronically or request extension – by March 1, 2023

In My Tax Account (MTA) – complete your 2023 T-R and T-P Forms for the December 31, 2023 filing period
Remember – you must file both T-R and T-P Forms even if you do not have personal or real property
You can request a filing extension in MTA – filing deadline with extension is April 3, 2023

Schedule R: Exempt Rural Broadband Property
- Schedule R is now located on our website
- Submit completed schedule by email or attach to your Telco submission in MTA
- Report all qualified broadband service property as defined in sec. 76.80(2)(2), Wis. Stats.
- 2022 claimed balances are shown on Schedule Y-P
- Report 2023 additions or deletions to Schedule R property on Schedule Y-P
Schedule C-1D: Non-Operational (Dark) Fiber Optic Cable
- Additional obsolescence for dark fiber installed during 2002 and prior years is discontinued starting in 2022
- Since DOR does not recognize additional obsolescence on dark fiber, Schedule C-1D has been discontinued and you no longer need to break out dark fiber costs. Report all costs associated with these years on Schedule C-1L.

One month or less – if you file within a month after the March 1, 2023 due date (or April 3, 2023 for an extension), DOR will charge you a 5% penalty of the 2023 taxes
For each additional month you are late – DOR will charge another 5%, not exceeding 25% of the total
