A Republican candidate who is running the Colorado state Senate faced tax liens and owed $40,000 in child support.

Timothy Arvidson, who is running to represent the Douglas County-based Senate District 2, earlier admitted he made mistakes in his past.

“I’ve owned them and own up to everything I have in my past. Everything in my past is 20 or 30 years ago,” Arvidson, 62, told Colorado Politics.

Previously, Colorado Politics reported that Arvidson’s past included domestic violence, four DUI charges between 1992 and 2006 and multiple restraining orders between 1996 to 2010. The criminal and civil complaints stretched across six separate jurisdictions: Arapahoe, El Paso, Jefferson, Denver, Douglas and Summit counties.

New information revealed that Arvidson has had five DUIs. He pleaded guilty to driving while impaired on two cases, including for an arrest in Arapahoe County in March 2002, which was adjudicated the following August.

He was fined $585 and sentenced to 48 hours of community service and five days in jail. The court records in 2003 showed he did not complete the community service.

In 2006, an arrest warrant was issued tied to that case, and he was arrested on August 3. No further information was available on what happened after that, although court records noted this was his second arrest under a driving while impaired charge.

The third arrest — for which he pleaded guilty — occurred in August 2006 in Douglas County on six charges related to driving under the influence and possession of marijuana. While medical marijuana was already legal in 2006, recreational marijuana was not legalized until 2012. The DUI charges included an open container, driving under the influence and possession of drug paraphernalia.

He failed to appear in court on the charges and his $10,000 bond was revoked. The case was resolved in May 2007, when the district attorney dismissed the charges but sought fines of about $250.

Arvidson also admitted to being about $40,000 in arrears in child support in Jefferson County, according to his personal financial disclosure statement filed with the Secretary of State when he became a candidate. 

Arvidson has had at least 10 tax liens levied against him in multiple states.

The state of Illinois sought a $3,056 tax lien in 2019, and a federal tax lien in 2017 of $9,213. In 2016, the IRS filed a federal tax lien in Colorado for $67,704. It followed two others from 2003 for $77,323 and $56,572.

The last lien showed as having been “released.” Arvidson and his then-wife, Denise, had a federal tax lien of $106,020 filed against them in 2003, which does show as released in 2005.

Another federal tax lien in 2001, released in 2003, was for $28,124.

The Illinois connection was for a business in which he was a senior vice president in Highlands Park, outside of Chicago.

Those federal tax liens, plus others that went back several decades and had been satisfied, totaled more than $357,000.

He also had a Colorado tax lien that went back several decades and which appeared to have been satisfied.

Arvidson admitted to $65,000 in debt to the Internal Revenue Service in his personal financial statement.

The candidate has held voter registrations in multiple states at the same time.

He first registered to vote in Colorado in 2002. Then in 2013, he registered to vote in Sarasota County, Florida. Voting records show he voted in one election in Florida in March 2021 for a special election. His Florida voter registration is now canceled. Arvidson owned two businesses in Florida during that time, according to the Florida Department of State.

In Colorado, Arvidson did not vote in any primary election between 2004 and 2018. He dropped his Republican affiliation in 2021 to become unaffiliated but changed back again to Republican in 2022, according to Secretary of State voting records.

Arvidson did not reply to a request for comment.
