Here’s a detailed LLC formation guide on filing taxes in Oklahoma.

Quick Summary

  • All members of an LLC in Oklahoma are required to pay self-employment tax at the rate of 15.3%.
  • LLCs with C-Corp status must pay federal corporate income tax at the rate of 21% and 4% corporate income tax.
  • Some LLCs pay Oklahoma sales tax on $100,000 worth of taxable merchandise.


How Are LLCs Taxed in Oklahoma?

LLCs in Oklahoma are taxed as pass-through entities based on the number of LLC members who pay individual income taxes on business profits and pay state pass-through entity tax of 4%.

However, the Oklahoma tax department also charges other federal, corporate, and income taxes for LLCs.

State Taxes for Oklahoma LLCs

In Oklahoma, the state taxes for LLCs are different depending on the structure of the LLC.

1. Single-Member LLC

A single-member LLC is considered a sole proprietorship by default status, which means your single-member LLC is not expected to submit federal tax returns.

Instead, you, as the owner, will file the return and pay federal income taxes. This is known as pass-through taxation, where the LLC doesn’t pay its own taxes.

2. Multi-Member LLC

A multi-member LLC owned by two or more owners is considered a partnership by default status.

Owners must report LLC income and expenses on their personal tax returns and are responsible for filing quarterly estimated LLC tax returns.

Your LLC should file a 1065 partnership return and send the owners a Schedule K-1, which has a distributive share of their profits.

Also, the K-1 income “flows through” to the owners. Then, the income taxes are paid by each owner on their personal income tax return (Form 1040) [1].

Additionally, each member must report their share of the LLC's income on their personal Oklahoma income tax return.

3. LLCs Taxed as S-corp

LLCs registered as S-Corp companies are exempted from paying additional federal income taxes. Your LLC keeps its pass-through status and does not pay the self-employment tax.

Owners are allowed to declare some of their income as salary and other income as withdrawals or distributions.

This means that the business's taxable income passes through to the owners liable for filing federal taxes.

To have your LLC taxed as an S-Corporation, you should submit Form 2553 to the IRS.

4. LLCs taxed as C-corp

C-corp LLC documents

The C-corp status is the default tax status used for corporations. However, very few LLCs choose to be taxed as C-corps.

Having your LLC taxed as a C-Corporation can help owners save money on healthcare fringe benefits. A C-corp is considered a legal entity separate from its shareholders and must submit a separate tax return.

LLCs taxed as C-corps must file separate tax returns and pay a flat corporate tax of 4% on their Oklahoma taxable income.

LLCs with C-corp status are required to pay federal corporate income tax at the nominal rate of 21%, Oklahoma’s 4% corporate income tax, and the state’s franchise tax on taxable earnings and then distribute money to the owners either by salary or dividends.

In addition to paying corporate taxes, owners must pay taxes at the individual level.

Dividends are taxed at 10% to 37%, depending on the shareholder’s tax bracket, while if owners take salaries, they pay 15.3% self-employment tax for Social Security and Medicare (FICA).

Your LLC can request to be taxed like a C-corporation by filing Form 1120 with the IRS [2].

Federal Taxes for Oklahoma LLCs

Shaking hands as a sign of agreement

LLCs in Oklahoma are not subject to federal income tax since they are considered pass-through entities. However, the owners pay federal taxes on the LLC’s income.

1. Federal Income Tax

You are required to pay federal income tax on the earnings you take out of your LLC. The sum of your tax depends on your current income tax bracket, earnings, filing status, and deductions.

The federal income tax often includes the profits you take out of your LLC, fewer allowances, and specific dedications such as some retirements and healthcare plans.

2. Federal Self-Employment Tax

All members of an LLC are required to pay self-employment tax. The federal self-employment tax applies to all members who take profits out of the business.

It is administered by the Federal Insurance Contributions Act (FICA), which includes Medicare, Social Security, and other benefits. In Oklahoma, the self-employment tax rate is 15.3%.

When calculating how much self-employment tax you may owe, you will be able to deduct your business expenses from your income.

However, you may pay less self-employment tax by treating your LLC as an S-Corp. This allows you to declare some of your earnings as salary and others as withdrawals or distributions.

Other Taxes

As a business owner, you must pay the Oklahoma Tax Commission these three types of Oklahoma tax. Also, you may be required to pay use tax depending on your business type.

These LLC business taxes apply despite having an S Corp or C Corp.

1. Oklahoma Income Tax

As an LLC owner, you will need to pay Oklahoma income tax on the earnings you pay yourself. Your employees are also required to pay the state income tax. 

The tax rates range from 0.5% to 4.75%, depending on the amount of your taxable income. Consult with a tax advisor to ensure that you meet the required amount.

Additionally, the Oklahoma Tax Commission requires every corporation to file a corporate income tax return at the rate of 4%.

2. Oklahoma Sales and Use Tax

You may need to collect Oklahoma sales tax at the point of purchase if your business involves certain services or physical products such as books, furniture, or raw materials.

Oklahoma does not levy sales tax on products regarded as necessities, including clothing, gas, and medication [3].

However, the sales tax in some regions may be high due to additional sales tax that local taxing jurisdictions may impose.

Additionally, Oklahoma requires business owners to pay use tax at the rate of 4.5% if they purchase physical products outside the state for use in Oklahoma.

3. Oklahoma Franchise Tax

LLCs in Oklahoma are not subject to the franchise tax but may still be subject to state income taxes requiring $1.25 for each $1000 of capital used in Oklahoma.

4. Local Income Taxes

In addition to state income taxes, Oklahoma LLCs may also be required to pay local income taxes.

These taxes are typically imposed by cities or counties and can vary depending on the location of the LLC. For instance, cities like Tulsa and Oklahoma City have local income taxes, while others may not.

To determine if your LLC is required to pay local income taxes, you should check with the local government where your LLC is located. This information is usually available on the city or county’s website or by contacting their tax department directly.

It’s crucial to stay informed about these local requirements to ensure compliance and avoid any penalties.

Moreover, some cities in Oklahoma impose a local sales tax, which can range from 1% to 4%. This tax is typically collected by the Oklahoma Tax Commission and distributed to the local governments.

Understanding both local income and sales taxes is essential for accurate financial planning and compliance.

5. Payroll Taxes (Oklahoma Employer Taxes)

If your LLC has employees, you will be required to pay payroll taxes, also known as Oklahoma employer taxes.

These taxes include:

  • Federal Income Taxes: You will need to withhold federal income taxes from your employees’ wages and remit them to the IRS.
  • State Income Taxes: You will need to withhold state income taxes from your employees’ wages and pay them to the Oklahoma Tax Commission.
  • Social Security Taxes: You are required to pay Social Security taxes on behalf of your employees.
  • Medicare Taxes: You must also pay Medicare taxes on behalf of your employees.
  • Unemployment Taxes: You will need to pay state unemployment taxes to the Oklahoma Employment Security Commission.

To comply with payroll tax requirements, you will need to:

  • Obtain an Employer Identification Number (EIN) from the IRS.
  • Register with the Oklahoma Tax Commission and obtain a sales tax permit.
  • File quarterly payroll tax returns with the Oklahoma Tax Commission.
  • Pay payroll taxes on time to avoid penalties and interest.

Additionally, as an LLC owner, you may be required to pay self-employment tax on your share of the LLC’s profits.

This tax is used to fund Social Security and Medicare, ensuring that you contribute to these essential programs.
