Understanding LLC Taxation Basics

How Mississippi LLCs Are Taxed By Default

Your Mississippi LLC doesn’t pay taxes itself. Instead, profits flow through to you and your members, who report them on personal tax returns. This is called pass-through taxation.

Here’s how it works:

  1. Your LLC earns income from business activities
  2. The LLC itself files no tax return (unless you elect otherwise)
  3. Profits “pass through” to members based on ownership percentage
  4. Each member reports their share on their personal tax return
  5. Members pay tax at their individual income tax rates

What this means for you: Unlike corporations, your business profits are only taxed once, which typically saves money.

Time-Saving Tip: If you’re uncertain about your LLC’s tax classification, a tax professional can review your LLC’s tax setup in 30 minutes and help you choose the most tax-efficient option.

Tax Classification Options

While pass-through taxation is the default, your Mississippi LLC can choose alternative tax treatments:

Default LLC Tax Status:

  • Single-member LLC: Taxed as a sole proprietorship
  • Multi-member LLC: Taxed as a partnership

Optional Tax Classifications:

  • S Corporation: Can reduce self-employment taxes by paying “reasonable salaries”
  • C Corporation: LLC pays corporate tax on profits, members pay personal tax on distributions (creates double taxation)

Mississippi Pass-Through Entity Tax Option:

  • Optional tax that allows LLCs taxed as partnerships or S Corps to pay tax at the entity level
  • Can help overcome the $10,000 SALT deduction limitation
  • Tax structure maintains until revoked by owners or shareholders

Federal Tax Obligations

Income Tax

As a Mississippi LLC owner, you’ll report your share of business profits on your personal tax return using:

Federal income tax rates range from 10% to 37% based on your tax bracket (actual brackets will depend on inflation adjustments and any tax law changes).

Simply Put: Whatever money your business makes (after expenses) gets added to your personal tax return, just like income from a job.

Self-Employment Tax

LLC members actively involved in the business must pay self-employment tax of 15.3% (covering Social Security and Medicare) on their share of LLC profits.

Key points:

  • Applies to net earnings of $400 or more
  • Calculated on Schedule SE
  • You can deduct 50% of the self-employment tax as an “above-the-line” deduction, which lowers your adjusted gross income

What happens if I miss this payment? The IRS charges penalties of 0.5% per month plus interest. However, first-time mistakes can often qualify for penalty abatement if you have a clean compliance history.

Employment Taxes

If your LLC has employees, you must:

  • Withhold federal income tax
  • Pay and withhold FICA taxes (7.65% each for employer and employee)
  • Pay federal unemployment tax (FUTA)
  • File quarterly employment tax returns (Form 941)
  • Provide W-2 forms annually

Estimated completion time: 2-3 hours per quarter (significantly less with payroll software or professional help)

Estimated Tax Payments

Because no tax is withheld from your LLC profits, you’ll likely need to make quarterly estimated tax payments using Form 1040-ES. These payments cover both income and self-employment taxes on your share of the business income. Missing deadlines or underpaying can lead to IRS penalties, even if you pay in full later.

Working with an accountant can help ensure accurate calculations, on-time payments, and a smarter overall tax strategy.

Key deadlines:

  • April 15
  • June 16
  • September 15
  • January 15

Pro Tip: Set calendar reminders 15 days before each deadline. This gives you time to prepare without the last-minute rush that leads to mistakes.

Mississippi State Taxes

Mississippi Income Tax

Mississippi has a personal income tax rate of 0%-4.7% that applies to your LLC’s profits on your personal return. 

This is a gradual rate that changes each tax year. Taxable income under $10,000 is 0%, the rate for higher income is as follows:

  • Tax year 2026 → 4% on taxable income over $10,000

Tax Strategies for Mississippi LLCs

S Corporation Election Benefits

Converting your LLC to an S Corporation for tax purposes can save on self-employment taxes:

  1. File Form 2553 with the IRS
  2. Pay yourself a “reasonable salary” subject to employment taxes
  3. Take remaining profits as distributions exempt from self-employment tax

Example: An LLC making $100,000 in profit pays 15.3% self-employment tax on the entire amount. As an S Corp, if $60,000 is a reasonable salary and $40,000 is taken as distributions, only the $60,000 is subject to employment taxes.

Potential Savings: In this example, you’d save about $6,120 in self-employment taxes.

Pass-Through Entity Tax Election

Consider electing Mississippi’s Pass-Through Entity Tax if:

  • You’re affected by the $10,000 SALT deduction cap
  • Your LLC has elected to be taxed as an s corp or partnership already
  • All members agree to the election

Business Expense Deductions

Common deductions Mississippi LLC owners often overlook:

  • Home office deduction
  • Business mileage (70¢ per mile for 2025)
  • Health insurance premiums
  • Retirement plan contributions
  • Professional development expenses

Mississippi LLC Taxes FAQs

If you own an LLC in Mississippi, the way you pay taxes is primarily structured as a pass-through entity. This means that any profits and losses will pass through to your personal tax returns. However, you may still be subject to the state’s annual franchise tax and owe state income taxes on any profits that you make.

If your Mississippi LLC elects to be taxed as a corporation, then it’s required to pay both income and franchise taxes in the state. The minimum franchise tax rate for corporations is $25. 

Mississippi business income tax is imposed on the income of corporations and pass-through entities (LLCs. corporations, partnerships) that operate in the state. The tax rate is graduated, ranging from 0% to 5%, depending on the taxable income level. The tax is due annually and can be paid online through the TAP system.
