How Are LLCs Taxed in Washington?

Checking documents about LLC taxes in Washington

LLCs are Taxed in Washington according to the tax structure outlined by the Internal Revenue Service (IRS), which is determined by the number of LLC Members. Notably, Washington State does not impose a state-level income tax [1].

It's important to emphasize that your chosen tax structure should be clearly defined in your LLC Operating Agreement, ensuring it aligns seamlessly with the established regulatory framework.

This is particularly relevant when considering topics such as gross receipts tax, personal property taxes, occupation tax, personal income tax, and the business and occupation tax.

State Taxes for Washington LLCs

Washington's absence of personal and corporate income tax exempts the majority of LLCs from state tax obligations, and Washington-based LLCs with employees must enroll for state unemployment insurance tax through the Employment Security Department.

Additionally, employer taxes, including federal and state requirements such as Social Security, Medicare, and unemployment insurance taxes, must be considered by LLCs with employees.

"Washington's unique absence of personal and corporate income tax positions it as an attractive hub for business ventures."

1. Single-Member LLC

Organizing single member LLC documents

The Internal Revenue Service designates all Single-Member LLCs as Disregarded Entities in terms of taxation.

Essentially, this means that the IRS doesn't anticipate the LLC itself to submit its federal income tax return.

Rather, the proprietor of the Single-Member LLC takes charge of the return filing and bears the responsibility for federal income tax payments.

The method by which the LLC fulfills federal income tax obligations hinges on the ownership structure:

  • If an individual owns the LLC, taxation mirrors that of a Sole Proprietorship.
  • If the LLC is owned by another company, taxation aligns with the role of a branch or division under the parent company.

2. Multi-Member LLC

When an LLC boasts ownership by two or more individuals, its taxation methodology mirrors that of a Partnership.

The LLC is required to submit a 1065 Partnership Return and furnish a Schedule K-1 to its owners.

These Schedule K-1 forms delineate each owner's proportionate division of profits. Consequently, the income specified in the K-1 "flows through" to the respective owners. Subsequently, each owner is accountable for settling income taxes on their personal tax return (Form 1040).

3. LLCs Taxed as S-Corp

Through the submission of Form 2553 to the IRS, your LLC can be taxed as an S-Corporation.

Opting for S-Corporation taxation can yield cost savings on self-employment taxes for businesses with established profits.

It's essential to factor in extra costs associated with S-Corporation taxation.

Typically, new business proprietors should consider this tax choice once their business is well-established and revenue streams are consistent.

4. LLCs Taxed as C-Corp

Upon submission of Form 8832 to the IRS, your LLC can seek the tax treatment of a C-Corporation.

Selecting C-Corporation taxation can benefit sizable employers aiming to economize on healthcare fringe benefits.

5. Business and Occupation (B&O) Tax

The Business and Occupation (B&O) tax is a gross receipts tax that applies to most businesses in Washington state, including LLCs. Unlike income taxes, the B&O tax is based on the gross income of the business, meaning it is calculated on the total revenue without deductions for business expenses.

The tax rate varies depending on the business classification, which is determined by the type of activity or industry.

For instance, the tax rate for retailing is 0.471%, while service and other activities are taxed at 1.5%. LLCs must file a B&O tax return and pay the tax on a periodic basis, which can be monthly, quarterly, or annually, depending on the assigned filing frequency.

6. Local Taxes

In addition to state taxes, LLCs in Washington state may be subject to local taxes, including personal property taxes, occupation taxes, and other local levies.

Local taxes vary depending on the jurisdiction, and LLCs must comply with the tax laws and regulations of the cities, counties, or special districts where they operate.

For example, personal property taxes are levied on the value of business assets such as equipment and furniture.

Occupation taxes, also known as business license taxes, may be imposed by certain cities or counties based on the type of business activity.

Federal Taxes for Washington LLCs

As the proprietor of an LLC, you are responsible for both self-employment tax and federal income tax, which are categorized under 'pass-through taxation.'

LLC members must also pay taxes on any profits generated by the LLC.

1. Federal Self-Employment Tax

Every member or manager who receives profits from the LLC is obligated to pay self-employment tax.

This tax falls under the purview of the Federal Insurance Contributions Act (FICA) and encompasses contributions to Social Security, Medicare, and other associated benefits.

Currently, the self-employment tax rate stands at 15.3 percent.

2. Federal Income Tax

In addition, you are required to remit standard federal income tax on any income you withdraw from your LLC.

The exact amount of income tax owed is contingent upon your earnings, current income tax bracket, eligible deductions, and filing status.

Federal income tax only applies to the profits you extract from your business after accounting for specific deductions and allowances.

This encompasses your tax-free portion, deductible business expenses, and other eligible deductions such as healthcare and certain retirement plans.

Alternatively, an LLC can elect corporate taxation by completing IRS form 8832 [2]. This choice is viable for those seeking to circumvent pass-through taxes.

Upon selection, the federal government imposes C corporation taxation upon the business.

Other Taxes

Washington enforces a range of additional LLC business taxes that encompass various sectors.

Businesses must collect retail sales tax when selling physical products or certain services, and this tax must be paid to the Washington Department of Revenue.
