Primary Concern:


Serious economic circumstances worldwide have done little to diminish Oklahoma's amazing economic growth since the year 2000. Due in large part to corporate friendly tax laws, Oklahoma has become a home to many new corporations, including a number of Fortune 500 companies.

Between 2000 and 2006, Oklahoma's growth domestic product grew an astonishing 50 percent, with a ten percent jump alone happening between 2005 and 2006.  Per capita income has also jumped tremendously during that same period, though the median income ranks as one of the lowest in the nation.   What perhaps makes Oklahoma's progress most astounding is the realization of how far they have come compared to where they were.

In the 1980s, Oklahoma was caught in a catastrophic economic megatrend, as the oil business that was the main driving force in the state's economy collapsed, driving almost 90,000 people into unemployment before 2000.

Over the next two decades Oklahoma steadily supplanted energy industries in their state with other industries, which include electronics, telecommunications, aviation, food processing, and agriculture.  Nowadays, oil production accounts for less than 20% of the state's total economy, and is being steadily supplanted by other industries.

Recently, Oklahoma has agreed to a budget that is projected to eliminate what was feared to have been a $1.2 billion budget deficit, based on what it hopes to be an increase in sales taxes collected on internet orders as well as increases in the collection of traffic fines, moratoriums on tax credits, and use of federal stimulus funds.

Oklahoma is expected to have an extra reserve of $100 million to help out in the case of unforeseen budget issues.  Indeed, it is a testament to Oklahoma's economic power and taxation policies that a state that was once one of the most depressed in the nation seems prepared to whether the present economic storm.

Income Taxes:


Oklahoma collects income taxes from all individuals who either reside in the state full or part time, or reside outside the state and draw income from inside Oklahoma.  Income tax in Oklahoma is at a progressive rate with staggered bracketing.

For single taxpayers and married individuals filing separately, they have to pay 0.5% of the first $1,000 of the total income.  Between $1,001 and $2,500, the tax is $5 (0.5% of $1,000) plus 1% of all income over the base of $1,001.  Between $2,501 and $3,750 the addition percent over the base is 2%.  Between $3,751 and $4,900 the additional rate over the base is 3%.

Between $4,901 and is $7,200 is an additional 4% over the base, and between $7,201 and $8,700 is an additional 5% over the base.  All income over $8,791 is 5.5% over the base in additional to all the staggered rates of the previous incomes.

For married couples filing jointly, qualifying surviving spouses, and heads of household, the rates remain the same but the bracketing is slightly different.  The first $2000 of income is taxed at 0.5%.  Between $2,001 and $5,000 the rate is 1 percent over the base of $2,001 plus the $100 (0.5% of $2,000) owed from the previous bracket.

Between $5,001 and $7,500 the rate is 2% of excess over the base in addition to all the taxes owed from previous brackets.  Between $7,501 and $9,800 the rate of excess is 3%.  Between $9,801 and $12,200 the rate of excess above the base is 4% and between $12,201 and $15,000 it is 5%.  All income above $15,001 is 5.5% above base plus all prior taxes owed.

Corporate Income Taxes:


Oklahoma has a flat corporate income tax of 6% that is levied on all businesses either located in the state or earning income from within the state.

Oklahoma also imposes a corporate franchise tax to all corporations doing business in the state.  The rate is $1.25 for every $1,000 of all capital used in Oklahoma.  Corporations doing business in Oklahoma but are based out of state are also subjected to a $100 per year assessment.

Oklahoma's fairly lenient corporate taxes have led to it being considered one of the more corporate friendly states in the country, which has helped spur its economic growth in the last decade.

Property Taxes:

Property taxes in Oklahoma are assessed on a county basis by a county assessor.  In Oklahoma all property both in terms of real estate and personal property, is subject to property taxes.  Personal property is assessed at about 10 to 15 percent of its cash value.  Real property is assessed at its use value.  This means that vacant or unused property may be charged as much as ten times as much as occupied property in most jurisdictions.  Rates can differ from county to county.

Property tax refunds can be given to individuals who have a total income of $12,000 or less and are at least 65 years of age and/or totally disabled.  There are also homestead exemptions, and additional homestead exemptions on individuals or households making less than $20,000 a year in total income.

Sales Tax:


Sales tax in Oklahoma is 4.5 percent, and unlike in many states, the tax does not exempt unprepared food (though it does exempt prescription drugs.)  Nearly all cities, towns, and counties in the state also supplement the sales tax with their own sales taxes, which are usually another 3 to 4%.  Typically sales taxes throughout Oklahoma are 7.5 to 8.5%.

Oklahoma also participates in the Streamlined Sales Tax Initiative. The Streamlined Sales Tax Initiative has the goal of stipulating uniform standards of item taxation and means by which states collect sales tax from businesses, since those can be distinctly different from state to state.

This is another element that makes Oklahoma appear very corporation friendly, as corporations who operate vendors in many different states must pay sales taxes in different ways depending on the state.

Oklahoma residents who live in the state year round and whose gross income is less than $20,000 annually can file for sales tax relief.  Some taxpayers who can claim a dependent and are age 65 and older, or are physically disabled, but make up to $50,000 a year can also claim relief.

Tax Forms:


Oklahoma's state income tax form is called the 511 form, and it features many variations (the 511NR, for instance, is for nonresidents.)  The estimated tax form is called the OW-8 (the OW-9 is for military spouses who implement a withholding tax exemption.)

Oklahoma tax form 538-S is for individuals that can claim sales tax relief/refund based on the standards listed above.

Introduction


The topic of tax is a sensitive one in any state. In Oklahoma, the discussion on tax has been heated, with many people expressing varied opinions. The primary objective of this article is to provide information on Oklahoma taxes, highlighting the current situation and any recent changes. Furthermore, the article aims to point out how the Oklahoma tax structure works, the taxes that the state imposes, and how they affect the residents.

Oklahoma tax Structure


Like most US states, Oklahoma has a unique tax system. The state constitution mandates that taxes can only be levied ""uniformly, upon the same class of subjects."" Personal income tax, sales tax, property tax, and excise taxes are some of the taxes that Oklahoma collects.

Personal Income Tax


Oklahoma has a progressive personal income tax system, composed of six tax brackets, with rates ranging from 0.5% to 5%. The Oklahoma Tax Commission (OTC) administers the income tax collection.

Individuals who have an income of less than $1,000 annually are not required to pay any personal income tax in Oklahoma. For individuals earning a maximum income of $8,300 annually, the state imposes a tax rate of 0.5%. The highest income tax rate of 5% applies to individuals earning $8,701 and above.

Sales Taxes


Oklahoma imposes a 4.5% state sales tax for most retail goods, which is then combined with city, county, and other special taxes in various areas, taking the overall tax a shopper pays to different levels. For example, Oklahoma City residents pay an 8.625% combined tax, while Muskogee residents pay 9.25%, including the city tax and county education tax.

Property Taxes


Property in Oklahoma is taxed by various jurisdictions, including school districts, cities, and counties, at varying tax rates. The amount that an individual pays in property taxes is determined by the assessed property valuation and the tax rate in the jurisdiction. Homeowners with a homestead exemption might receive a tax break.

Excise Taxes


Like in many other US states, excise taxes also apply in Oklahoma, where various goods and activities such as tobacco and gasoline are taxed.

Tax Credit Programs in Oklahoma


Oklahoma offers a few tax credit programs meant to encourage businesses to set up in the state and provide incentives for some taxpayers. Below are some of the tax credit programs that Oklahoma provides:

1. Historic Preservation Tax Credit program - This credit is meant to incentivize the preservation of buildings in the state by offering up to 20% of the expenses that the property owner incurs in eligible renovations or refurbishments.

2. Oklahoma Small Business Capital Formation Incentive program – provides a credit to individuals who invest in small businesses with revenues of less than $10 million, subject to a few limitations.

3. Land donation credit - This program provides a tax credit to those who donate land to conservancies and other similar nonprofit organizations.

4. Investment/New Jobs Credit - This credit program serves as an incentive to businesses that add jobs and invest a specific amount of capital in Oklahoma.

Recent Oklahoma Tax Changes


Over recent years, Oklahoma has made several changes to its tax structure, some of which impacted residents positively, while others had negative ramifications.

1. High-Income Tax Increase

During the 2021 Legislative Session, legislators agreed to increase the top income tax rate from 5% to 6% for individuals earning over $200,000 and joint filers earning over $400,000. The tax rate for earners below these levels remained unchanged.

2. Lowered the Corporate Income Taxes

In 2020, Oklahoma lowered the corporate tax rate from 6% to 4%. This move was aimed at encouraging business growth and creating jobs in the state.

3. Sales Tax on Online Purchases

In 2018, Oklahoma implemented a sales tax collection requirement for online retailers. The law mandates that if a seller who has no physical presence in Oklahoma realizes over $100,000 or makes at least 200 transactions in the state, they're required to collect and remit sales taxes to Oklahoma.

4. Education Credit Caps

In Oklahoma, tax credits for education come from two types of programs - one offering tax credits for private school scholarships, while the other offers credits for individuals contributing to public schools. In 2020, lawmakers reduced the maximum education tax credit available to a single taxpayer from $1,000 to $625.

5. Tax on Wind Energy

The Oklahoma legislature approved increasing the tax rate on wind energy production from 0.5% to 3% in 2017. This move was controversial since the tax rate on other oil and gas production remained the same.

How Taxes Impact Oklahoma Residents


Tax rates, structure, and credits are essential because they impact the residents of Oklahoma. Let's take a closer look at how these taxes work and how they impact Oklahoma residents:

1. Personal Income Tax

The progressive income tax in Oklahoma means that individuals earning more money pay a higher tax rate. For instance, if an individual earns $15,000 annually, their tax rate is 1%; meanwhile, a taxpayer earning $250,000 pays up to a 5% tax rate. This tax structure affects residents differently by their income levels and the amount of taxes they owe the state.

2. Sales Taxes

Sales taxes affect Oklahoma residents differently, depending on the sales tax rate on various items. The overall taxes that an individual pays are determined by the location of the purchase, the type of product bought, and other unique local taxes. With a 4.5% sales tax rate, Oklahoma is among the states with the lowest sales tax rates, positively impacting residents.

3. Property Taxes

Property tax rates vary according to the assessed property valuation and the tax rate in various jurisdictions. Homeowners who don't have homestead exemptions pay higher taxes than those with getting one. Furthermore, property taxes in urban and rural areas of Oklahoma vary, meaning the tax burden is different depending on where one lives.

4. Excise Taxes

Excise taxes on items like gasoline and cigarettes impact consumers differently, depending on various factors such as income and spending habits. The tax amounts on excise taxes remain the same regardless of income, meaning low-income households that might struggle to afford these items pay a relatively higher percentage of their income towards these taxes.

Conclusion


Oklahoma tax has remained a divisive and emotive subject among residents and policymakers in the state. Understanding the tax structure is essential in comprehending the taxes that the state imposes and how they impact residents. While tax policies can be controversial, Oklahoma has attempted to make a few changes to encourage business growth and job creation. As the state continues to make changes in the tax system, it's essential to ensure that those changes positively impact the residents more than anything.
