Expert Tax Prep for Every Business Structure

LLCs:

If you own a single-member LLC as a foreign person, the IRS treats it as a disregarded entity by default. This means the LLC itself doesn’t pay taxes, but it must file Pro Forma Form 1120 and Form 5472 to disclose transactions between the LLC and its foreign owner or related parties. Additionally, if the LLC has engaged in U.S. trade or business, the owner needs to file Form 1040-NR to report income and claim deductions.

For multi-member LLCs, the IRS classifies them as partnerships, requiring Form 1065 and Schedule K-1s for each partner.

Failure to file forms like Form 5472 can result in penalties starting at $25,000 per missed filing. Timely and accurate submissions are essential to avoid such costly penalties.

Partnerships:

In case your business structure is a Partnership, you’ll need to file Form 1065, U.S. Return of Partnership Income, to report income, deductions, and distributions. Each partner receives a Schedule K-1 detailing their share of the partnership’s results. Nonresident partners must file Form 1040-NR if they receive U.S.-sourced income.

If the partnership pays FDAP (Fixed, Determinable, Annual, or Periodical) income to foreign persons, such as dividends, interest, or royalties, it must withhold taxes and report the payments using Forms 1042 and 1042-S. Additionally, income connected to a U.S. trade or business requires withholding and reporting on Forms 8804, 8805, and 8813.

Penalties for non-compliance can add up quickly—$210 per partner per month for late filings of Form 1065 and steep fines for missing 1042 or withholding filings.

At Duatax, we ensure your partnership meets all IRS requirements on time, keeping you compliant and penalty-free.

C-Corps:

As a C Corp, you’ll need to file Form 1120, U.S. Corporation Income Tax Return, to report your corporation’s income and deductions. If you or other foreign shareholders own 25% or more of the company, Form 5472 is also required to disclose any reportable transactions. Missing deadlines can cost you, with penalties starting at $25,000 for Form 5472 or 5% of unpaid taxes for late Form 1120 filings. 

At Duatax, we guide you through these obligations seamlessly so you can avoid penalties and focus on your business.
