One of the most common questions self-employed drivers ask is whether forming an LLC changes how they deduct business mileage. The short answer is that your LLC vs sole proprietorship mileage deduction works the same way in most cases, but the business structure you choose can have a significant impact on your overall tax picture.
Understanding these differences matters because mileage is often the largest single deduction for self-employed professionals. At the 2026 IRS rate of 72.5 cents per mile, a freelancer driving 20,000 business miles claims a $14,500 deduction. How that deduction flows through your tax return depends on your entity type.
The Default: Single-Member LLC Equals Sole Proprietorship
A single-member LLC is what the IRS calls a “disregarded entity.” For federal tax purposes, it does not exist separately from you. Your LLC income, expenses, and mileage deductions all go on Schedule C of your personal Form 1040, exactly the same as a sole proprietorship.
This means a single-member LLC and a sole proprietorship use the same mileage deduction method. Both can choose between the standard mileage rate (72.5 cents per mile for 2026) and the actual expense method. Both report the deduction on the same tax form. Both reduce self-employment income dollar for dollar. Both face the same 15.3 percent self-employment tax on net income.
If you formed a single-member LLC purely for liability protection (which is a valid reason), your mileage deduction does not change at all. You still track miles the same way and claim the same deduction.
When the LLC Difference Matters: S-Corp Election
The real tax advantage of an LLC comes when you elect to be taxed as an S-Corporation. This is where mileage deductions work differently.
With an S-Corp election, you pay yourself a reasonable salary as a W-2 employee of your own company. The remaining profit passes through to you as a distribution. Distributions are not subject to the 15.3 percent self-employment tax, which is the primary tax benefit.
Here is how mileage works under an S-Corp structure. The S-Corp (your company) reimburses you for business mileage at the IRS rate under an accountable plan. The reimbursement is a tax-free payment to you and a deductible business expense for the S-Corp. You do not claim a mileage deduction on your personal return because the company already deducted it.
Compare this to a sole proprietorship where you deduct mileage on Schedule C. The tax savings come from the S-Corp paying you less in salary (which reduces payroll taxes) while covering your vehicle costs through the reimbursement plan.

Multi-Member LLCs and Partnerships
If your LLC has two or more members, the IRS treats it as a partnership by default. Partnership mileage deductions work differently.
The LLC itself does not claim the mileage deduction on its partnership return (Form 1065). Instead, each partner deducts their own business mileage as an unreimbursed partner expense on their personal Schedule E. Alternatively, the partnership can establish an accountable plan to reimburse partners for mileage, which is then deducted as a business expense on the partnership return.
The reimbursement route is typically cleaner because it keeps vehicle expenses on the business side of the ledger. Talk to your accountant about which approach makes sense for your partnership.
How to Claim Your Mileage Deduction by Entity Type
Here is a quick reference for where your mileage deduction appears on your tax return.
Sole proprietorship. Schedule C, Line 9 (Car and truck expenses). You deduct mileage directly against your business income.
Single-member LLC (default). Same as sole proprietorship. Schedule C, Line 9.
LLC taxed as S-Corp. The S-Corp reimburses you via an accountable plan. The company deducts the reimbursement on Form 1120-S. You receive the payment tax-free and do not claim a personal deduction.
LLC taxed as C-Corp. Similar to S-Corp. The corporation reimburses you and deducts the payment. However, C-Corp profits are taxed at the corporate level (21 percent) and again when distributed as dividends, making this structure less common for small businesses.
Multi-member LLC (partnership). Either each partner deducts on Schedule E, or the partnership reimburses and deducts on Form 1065.
State-Level Differences to Consider
While the federal mileage deduction is the same for LLCs and sole proprietorships, state-level costs can affect your overall calculation.
Most states charge an annual LLC filing fee or franchise tax. California’s LLC fee starts at $800 per year regardless of income. Texas imposes a franchise tax on LLCs that exceeds certain revenue thresholds. Other states like Wyoming and Nevada have minimal LLC fees.
These annual costs reduce the net tax benefit of an LLC. If you formed an LLC solely for mileage-related tax advantages, the savings may not offset the filing fees, especially in high-fee states. The LLC makes more sense when you factor in liability protection and the potential for an S-Corp election at higher income levels.
When to Consider Changing Your Business Structure
Mileage deduction alone should not drive your entity decision, but it plays a role in the bigger picture. Consider these guidelines.
Stay as a sole proprietorship if your net income is under $50,000 to $60,000, your mileage deduction is your primary write-off, and you want the simplest tax filing possible.
Form a single-member LLC if you want liability protection, your industry carries lawsuit risk, and you plan to eventually elect S-Corp taxation as income grows.
Elect S-Corp taxation if your net income consistently exceeds $60,000 to $80,000, you drive significant business miles (creating large reimbursement opportunities), and the payroll tax savings outweigh the added accounting costs. Learn more about how to claim mileage on taxes when self-employed.
Track Your Miles Regardless of Entity Type
