Introduction
If you own an LLC, 2026 is going to be a confusing year.
New laws are taking effect, deadlines are shifting, and the IRS has unleashed a new wave of audits on partnerships.
But it’s not all bad news. The “Bonus Depreciation” rule has been restored to 100%, and the controversial “BOI Reporting” requirement has seen massive changes that might save you time.
In this ultimate guide, we break down everything an LLC owner needs to know for the 2026 tax season—from filing deadlines to the “hidden” deductions that can save you $5,000.
Part 1: How is My LLC Taxed?
The IRS doesn’t have a tax form for “LLC.” Instead, they treat you based on how many owners you have. This is the #1 source of confusion for new founders.
1. Single-Member LLCs (Disregarded Entity)
If you are the only owner, taxes are easy. You file a Schedule C with your personal return.
- Deadline: April 15, 2026.
- Complexity: Low.

2. Multi-Member LLCs (Partnership)
If you have a partner, you are a “Partnership.” You must file Form 1065 and issue K-1s to partners.
- Deadline: March 16, 2026 (Note: This is one month early!).
- Complexity: High. You need specialized software.
- Recommended Tool: 👉 TurboTax Business (Review)
3. S-Corp Election (The Tax Hack)
Once your LLC makes over $80,000 in profit, you can ask the IRS to treat you as an “S-Corp.” This can save you thousands in Self-Employment taxes, but it requires running payroll.
Part 2: The 2026 Tax Deadlines (Don’t Miss These)
Mark these dates on your calendar. Missing them triggers a penalty of $220 per partner, per month.
- January 31, 2026: Deadline to send 1099-NEC forms to contractors.
- March 16, 2026: Deadline for Multi-Member LLCs and S-Corps (Form 1065/1120-S).
- April 15, 2026: Deadline for Single-Member LLCs and C-Corps (Form 1040/1120).
Part 3: 2026 Tax Deductions (Write Off $5,000+)
The best way to pay less tax is to track your expenses. For 2026, the limits have increased.
- Startup Costs: Deduct the first $5,000 of startup expenses (legal fees, branding) immediately.
- Mileage Rate: The standard rate is now 70 cents per mile.
- Bonus Depreciation: You can now write off 100% of the cost of equipment (laptops, desks) in Year 1.

Part 4: Breaking News – The “BOI” Reporting Update
For the last year, LLC owners have been panicked about the Beneficial Ownership Information (BOI) report.
The Update (March 2025): Following recent court battles, FinCEN has issued interim rules that may exempt US domestic entities from this reporting requirement.
- Previously: Every LLC had to file by Jan 1, 2026.
- Now: Watch the news closely. You may be off the hook.
However, if you do business in New York, a new “LLC Transparency Act” goes into effect January 1, 2026 that mimics the federal rule.
