Home Energy Audits: Missouri Personal Income Tax Deduction

Interested in making energy-efficiency upgrades and improvements to your home? You may qualify for a deduction on your Missouri personal income taxes.

Senate Bill 1181, passed by the General Assembly and signed into law in 2008, includes a Missouri personal income tax deduction for qualified home energy audits and the recommendations of those audits, beginning with the 2009 tax year. SB 601 passed in 2014 extended this tax deduction through December 31, 2020.

A Home Energy Audit must be performed before implementation of energy efficiency upgrades to be eligible for the tax deduction.

Any taxpayer who paid an individual certified by the Division of Energy to complete a home energy audit may deduct 100 percent of the costs incurred for the audit and the implementation of any energy efficiency recommendations made by the auditor. The maximum subtraction may not exceed $1,000 per year, for an individual taxpayer or $2,000 per year for taxpayers filing combined returns. To qualify for the deduction, you must have incurred expenses in the year you are filing a claim, and the expenses incurred must not have been excluded from your federal adjusted gross income or reimbursed through any other state or utility energy program.

Auditor Certification

The department has certification requirements and guidelines for energy auditors to help insure that residents and businesses are getting the most up-to-date advice and financially beneficial recommendations on methods to reduce their energy consumption.
