US LLC Tax Calculator

Use this calculator to estimate common US LLC tax amounts for owner income and business profit.

What this calculator does

The US LLC tax calculator estimates taxes for common limited liability company setups, especially pass-through LLCs where business profit flows to the owner.

It uses:

• annual business profit
• owner salary or draws
• self-employment tax assumptions
• estimated federal income tax rate
• optional state tax assumptions

This gives you a planning estimate for owner tax burden and take-home income.

LLC Tax Formula

For a simple single-member LLC taxed as a disregarded entity:

Estimated Tax = Self-Employment Tax + Federal Income Tax + State Tax

Where:

• Self-employment tax applies to net earnings from self-employment
• Federal income tax applies to taxable income after deductions
• State tax depends on the state and business structure

LLCs can also elect S corporation or C corporation tax treatment, which changes how salary, distributions, and payroll taxes work.

Example calculation

If an owner has 90,000 in net LLC profit, the calculator can estimate self-employment tax first, then layer on federal and state income tax assumptions.

The result is not a final tax return. It is a planning estimate that helps you decide how much to reserve for taxes and whether to discuss entity tax treatment with a professional.

When to use this calculator

Use this calculator when you want to:

• estimate tax on single-member LLC profit
• compare owner draws with estimated after-tax income
• plan quarterly estimated tax payments
• evaluate whether S corporation taxation may be worth discussing with a CPA

For self-employment tax only, use the Self-Employment Tax Calculator.

FAQs

Does an LLC pay federal income tax directly?

Usually not if it is taxed as a pass-through entity. Profit flows to the owner or members and is reported on their tax returns. LLCs taxed as C corporations are different.

Is LLC income subject to self-employment tax?

For many single-member LLCs and active owners, yes. Net earnings can be subject to self-employment tax unless the LLC has elected a different tax treatment.
