For foreign entrepreneurs with U.S. LLCs, the compliance period from November to March is the most crucial. Failing to complete the required IRS and state-level obligations during this time can lead to significant delays and penalties. By following this checklist, foreign LLC owners can stay fully compliant, avoid costly issues, and ensure smooth filings for the upcoming tax season.

Why November to March Matters for Foreign LLC Owners

The American tax year runs from January 1 to December 31. With multi-member LLCs, regardless of whether the business made a profit, tax returns must be filed. As for foreign-owned LLCs that are taxed as partnerships, the LLC must file Form 1065 returns by March 16, 2026. This form is used for partnership income, deductions, and expenses. A foreign partner also receives a Schedule K-1 and must file Form 1040-NR by April 15, 2026.

State annual reports also need to be taken into account. Most states and jurisdictions also require annual or biennial reports to be filed. If not filed, the state may take administrative dissolution actions, and the LLC may incur reinstatement fees.

Key IRS Tax Deadlines for the 2026 Season

Keep in Mind: The IRS has a $220 monthly (or portion thereof) penalty for each partner for up to 12 months for late filing of Form 1065. In a two-member LLC, one partner can owe the IRS $5,280 for a year of filed Form 1065 late, even if there are no tax liabilities.

Documents Foreign Founders Need to Prepare

These documents need to be gathered before the start of your compliance process:

• EIN and LLC Operating Agreements – Your Employer Identification Number is needed for all IRS filings, and the Operating Agreement contains important details about your profit-sharing percentages.
• 2025 Financial Statements – Profit and loss statement and a balance sheet for the entire 2025 calendar year, reflecting all business income, expenses, assets, and liabilities.
• Member Ownership Records – Ownership percentages and each member’s capital contributions, distributions, and ending capital account balances must be documented in detail.
• Proof of ITIN – Non-resident members need an ITIN if they don’t have a Social Security number. Expect issuances to take 8 to 12 weeks or longer if in the peak season.
• Prior-Year Returns – If your LLC has filed previously, it is best to keep a copy of Form 1065 and K-1 to ensure consistent reporting.

State Annual Compliance Checklist

Meeting the federal IRS compliance guidelines is only part of the picture. Each state adds its own stipulations:

Annual Report Filing – Most states expect LLCs to file annual reports, which include company information updates, such as the member names, the registered agent name, and the addresses of the business. Fees associated with this vary widely by state (Delaware: $300, Wyoming: $60).

Registered Agent Renewals – Your registered agent must have a physical address in your LLC’s state of formation and have availability during business hours. Make sure your agent is active and their contact information has been updated.

Franchise Tax Payments – Some states charge franchise taxes based on revenue, assets, or annual flat fees. Inactive businesses in California are still subject to the $800 franchise tax.

Business License Renewals – Check the renewal dates on business licenses or permits, as the renewals may be on cycles independent of tax deadlines.

IRS Tax Filing Checklist for Foreign-Owned LLCs

This guide simplifies the process for foreign founders’ LLC IRS filing:

1. File Form 1065

As a partnership return, reporting total income, deductions, credits, and financial information, even for zero activity, you must file to avoid penalties. It also contains schedules for balance sheet information, income reconciliation, and partner capital accounts.

2. Distribute Schedule K-1 to Partners

Each member must be given their K-1 that shows the distributive share of income, deductions, and credits, which is due to them by the Form 1065 filing date.

3. File Form 1040-NR for Each Foreign Member

Each foreign partner needs to report K-1 income and file the return to assess U.S. tax liabilities. This form requires special consideration of U.S. tax treaty provisions, which may reduce tax obligations.

4. Submit Form 5472 (If Necessary)

Foreign-owned LLCs with 25% ownership or more with foreign ownership and classified as corporations must file Form 5472 to report transactions with foreign related parties.

5. Apply for Form 7004 Extension if Needed

You can file the extension request by March 16 for a six-month extension on tax filing. Any tax owed will still be needed to file by the original deadline to avoid interest charges.

Key Compliance Tips for 2026

Start Early – Start the document collection process in November. Waiting until February does not give enough time to address complications like missing ITINs or incomplete financial records.

Maintain Clean Books – Clean records make it easy not to forget and ensure all records and files necessary to complete the compliance are in the set. Last-minute bookkeeping usually results in the loss of deductible expenses and mistakes.

Understand Treaty Benefits – Certain countries have treaties with the U.S. that can help reduce or remove some taxes. Be sure to include the benefits on your Form 1040-NR.

Consider Estimated Taxes – Foreign members of your LLC may have to make quarterly estimated tax payments to avoid underpayment penalties if your LLC makes a lot of money.

Document Your Communications – Hold on to emails regarding your timeline with the IRS, state filings, and compliance deadlines. This can help answer questions that come up later.

Common Mistakes to Avoid

Foreign LLC owners often make these mistakes:

• Filing as a single-member LLC when there are multiple members – This means you filed incorrectly and will get penalties for not filing Form 1065.
• Missing the ITIN application deadline – ITINs are necessary to file completed tax returns.
• Ignoring state requirements – You have to meet state demands as well, even if you meet the federal requirements.
• Not sending the K-1s out in time – Your partners need K-1s to file their personal tax returns.
• Not paying estimated taxes throughout the year – This will result in underpayment penalties.
