Since his 2010 election, Brumbaugh authored 18 bills (14 House bills and 4 Senate bills) which have been signed into law. Brumbaugh's HB 2908 seeks to transform state government process by allowing state agencies to pool inefficient processes into a single efficient process potentially saving millions of taxpayer dollars. Likewise, HB 2912 removes unnecessary bureaucratic red tape and SB 436 allows Oklahoma school district to cut through costly administrative overhead. His HB 1989 created the "Student Data Accessibility, Transparency and Accountability Act of 2013 ". It prevents certain aspects of student data from being shared by government officials. HB 1489 from the 2011 session, known as the "Taxpayer Transparency Act," makes all state road funding available online to the public. Brumbaugh stated, "With the problem of almost 80% of road funding through some sources going to non-transportation agencies, this will help make everything more transparent, accessible, and understandable. Hopefully this will be a start in the process of getting resources to our crumbling roads and bridges where they need to be." HB 1489 was eventually signed into law by
Governor Mary Fallin on May 19, 2011. Brumbaugh authored HB 1488 to extend incentives for oil and gas production and keep jobs in Oklahoma. It was signed into law on May 20, 2011. In 2012, Brumbaugh proposed legislation to eventually end Oklahoma's state income tax. "In the past decade, states without a personal income tax outpaced Oklahoma in economic growth and job creation," said Brumbaugh. "Those states also doubled Oklahoma's rate of state and local tax revenue growth. Basically, as those states attracted productive individuals, those individuals gave more to state and local governments through sales and property taxes and the like". The bill, sponsored by 23 members of the House of Representatives, would gradually phase out state income tax by decreasing percentages until 2022 when the percentage would be zero. In 2015, Brumbaugh won approval for HB 1008, the "Urban Renewal Transparency Act" which provides additional notice and hearings before local governments can take private property using eminent domain. Brumbaugh's House Bill 1007, the "Protecting Religious Liberty Act" protects licensed or ordained religious officials from solemnizing or recognizing any marriage that violates their conscience or religious beliefs. Both bills were signed by the Governor. ==Convention delegate==
