Sooner State income tax forms are due April 15, or the next business day if that date falls on a weekend or holiday.
Oklahoma's sales tax rate is 4.5 percent.
Oklahoma is a participant in the Streamlined Sales Tax Initiative, or SSTI, designed to create a nationwide, simplified system to bring uniformity to definitions of items in the sales tax base, reduce the paperwork burden on retailers and incorporate new technology. A document by the Streamlined Sales Tax Governing Board lists the taxable items under Oklahoma law in relation to the SSTI.
Oklahoma residents who live in the state for the entire year and whose total gross household income is $20,000 or less can file for sales tax relief. Taxpayers who can claim an exemption for a dependent, are age 65 or older or who are physically disabled and make up to $50,000 also are eligible.
The sales tax refund can be claimed by filing Form 538-S along with personal state income tax returns by the April due date. If no state income tax return is required, the form can be filed separately by June 30 (or the next business day if June 30 falls on a weekend) with the Oklahoma Tax Commission.
State law allows incorporated cities and towns as well as counties to levy local sales and use taxes for general and specific purposes of municipal government.
Personal and real property taxes
Property taxes, also known as ad valorem taxes, are the primary source of funding for county government operations.
Property taxes are paid based on the value of a taxpayer's property. The county assessor, a locally elected officeholder, determines the value of most property in the county for tax purposes.
Taxpayers owning tangible personal property in the state of Oklahoma must file a property tax return with each county where property was located Jan. 1 of each year on or before the following March 15. Personal property then is assessed at an amount between 10 percent and 15 percent of its fair cash value.
Real property is also assessed as of Jan. 1. It is valued at its "use value" fair cash value for the highest and best use for which the property was actually used (or classified for use) during the previous calendar year.
A homestead exemption of $1,000 of the property's assessed valuation is available to homeowners living in the property as of Jan. 1.
Oklahoma offers homeowners a credit for or refund of property taxes by filing Form 538-H.
Some older Oklahoma residents also are entitled to a property valuation freeze by filing Form OTC 994. While you can download OTC 994 from OKAssessor.com by selecting your county and then clicking "tax forms," the document must be completed at your county courthouse.
Many questions regarding property tax issues are handled at the county level. Each of Oklahoma's 77 counties has a county tax assessor. Information on your county assessor is available at the state's tax website.
Further questions regarding property tax issues can be directed to the Oklahoma Tax Commission's Ad Valorem Division at (405) 319-8200.
