LLC Tax Deductions: What You Can Write Off in 2026

Learn which LLC tax deductions you can claim in 2026, from home office to vehicle costs. Practical guide to lowering your small business tax bill.

LLC tax deductions let you lower your taxable income by writing off the ordinary and necessary costs of running your business. As an LLC owner, you report business income on your personal return, and the deductions you claim directly reduce what you owe. This guide covers the most common deductions and how to track them.

How LLC taxes work

An LLC is a pass-through entity, which means the business itself does not pay income tax. Instead, profits flow through to your personal return, and you pay tax on them. That makes deductions especially valuable, because every dollar you write off is a dollar you do not pay tax on.

To claim a deduction, the expense must be ordinary and necessary for your business. Ordinary means common in your industry, and necessary means helpful and appropriate. Personal expenses generally do not qualify.

Common LLC tax deductions

Most LLC owners can claim a range of business expenses. The most common ones include:

• Home office if you use part of your home regularly and exclusively for business
• Vehicle costs for business travel, using either the standard mileage rate or actual expenses
• Equipment and supplies like computers, software, and office materials
• Marketing including ads, website costs, and promotional materials
• Professional fees for accountants, lawyers, and consultants

These are the basics, but the full list is longer. Keep receipts for everything so you can back up your claims if the IRS asks.

Home office deduction

If you work from home, you may qualify for the home office deduction. The space must be used regularly and exclusively for business, meaning it is not also your living room. You can use the simplified method, which gives a flat rate per square foot, or the regular method, which tracks actual expenses.

The simplified method is easier and works well for most small businesses. It gives a set deduction based on the size of your office, up to a limit. The regular method can yield more but requires more record keeping.

Vehicle and travel deductions

If you drive for business, you can deduct vehicle costs using the standard mileage rate or actual expenses. The mileage rate is simpler, but you need to track your business miles. Travel for business, including lodging and meals, is also deductible, though meals are often limited to a portion of the cost.

Keep a log of your business miles and save receipts for travel. The IRS expects you to separate business use from personal use, so good records are essential.

Tracking your deductions

Good record keeping makes tax time much easier. Keep receipts, bank statements, and a log of business expenses throughout the year. Many LLC owners use accounting software or a separate business bank account to keep things organized.

Separating business and personal finances also strengthens your LLC and simplifies your deductions. For more on that, read our LLC bank account guide.

Getting help

Tax rules change and vary by situation, so it is worth working with a tax professional who understands small businesses. They can help you claim every deduction you qualify for and avoid mistakes.
