Various tax liabilities can result from making improvements or modifications to real property. The parties liable under the city code, as well as the types and amounts of tax due, will depend upon the project. Each party involved, including owners, primary contractors, and subcontractors, is charged with understanding their respective liability.
Taxpayers may not avoid assessment or payment by virtue of private contract provisions specifying that another party is liable for taxes resulting from the project. A taxpayer's inability to recover assessed taxes from another party, such as a primary contractor or property owner, will not be cause for abatement. Failing to timely file or pay taxes due may result in additional fines, penalties and interest, and can even result in liens against the property improved.
