Introduction: Tax Season and its importance for businesses

The Tax Season in the United States is the period in which individuals and businesses must file their tax returns with the Internal Revenue Service (IRS). For LatAm businesses with LLCs in the United States, this process can be especially challenging due to both local and international tax and accounting regulations.

At Marco, we understand the challenges businesses face and offer solutions that ensure compliance with their tax and accounting obligations in an efficient and secure manner. Below, we present a complete guide to navigating Tax Season and optimizing the process in 2025.

Key obligations for LLCs in the United States

If you own an LLC in the United States, it is essential to comply with certain obligations to maintain its good legal and tax standing. Below are the essential steps:

Tax Return: You must file an annual return, regardless of whether your LLC has generated income or not. 

Registered Agent Maintenance: It is mandatory to have a Registered Agent in the state where the LLC was formed. This agent acts as the official point of contact between your company and the state authorities. Make sure the agent's information is always up to date and that the associated fees are paid on time.

Annual Report Filing: Most states require LLCs to file an annual report that includes updated information about the company and its members. However, some states, such as New Mexico, do not require this report. Check the specific regulations of the state where your LLC is registered to ensure proper compliance.

Key deadlines:

• March 15: Applies to Multi-Member LLCs.

• April 15: Applies to Single-Member LLCs. 

Important considerations:

• Filing the tax return is mandatory, even if your LLC has not had any business activity during the fiscal year.

• Failure to comply with these obligations can result in significant fines and penalties.

It is advisable to maintain constant communication with a specialized tax advisor to ensure that all obligations are fulfilled properly and within the established deadlines.

When is Tax Season in the United States?

Tax Season generally begins on January 1 and runs until April 15 each year, although the exact dates may vary slightly. This deadline applies to both individuals and businesses. 

Key dates in 2025:

• Filing begins: January 1, 2025.

• General deadline: April 15, 2025.

• Extension for returns: until October 15, 2025 (only if requested in advance).

It is crucial for businesses to prepare in advance to avoid penalties and ensure proper filing.

Why is Tax Season especially challenging for LatAm companies with LLCs in the United States?

Companies that operate internationally or have LLCs in the United States must consider the following tax obligations:

• International income reporting: If your LLC generates income in other countries, this must be reported in accordance with U.S. tax laws.

• State and federal regulations: Each state has specific tax laws in addition to the IRS federal regulations.

• Accounting compliance under different standards: Your company may need to adhere to standards such as GAAP (Generally Accepted Accounting Principles) or IFRS (International Financial Reporting Standards).

• Double taxation: It is crucial to avoid paying taxes twice through international tax treaties.

At Marco, we help LatAm companies with LLCs in the United States comply with these obligations in a simple and efficient way.

How to prepare for Tax Season 2025: Key tips

1. Organize your documentation in advance

Make sure you have all the necessary financial records, including:

• Profit and loss statements (P & L).

• Income and expense statements.

• International transaction reports.

• Previous tax forms, such as 1099 or W-2.

2. Stay up to date with tax regulations

The IRS constantly updates tax rules and forms. It is vital to have a team that understands these changes and applies them on time.
