On December 13, 2016, final regulations were issued regarding new reporting requirements for domestic disregarded entities wholly owned by a nonresident, whether the nonresident owner is an individual or an entity. The most typical domestic disregarded entity is a single member Limited Liability Company (Single Member LLC).

These rules are in effect for tax years beginning on or after January 1, 2017 and they are extremely relevant now since we are in tax season for the year 2017. The new rules do not apply if the Single Member LLC has already made the election to be treated as a corporation.

Historically, for tax purposes, a foreign-owned U.S. disregarded entity was just that – disregarded. The reporting taxpayer was the owner of the disregarded entity, whether the owner was an individual or an entity.

Under the new requirements, a domestic disregarded entity will have a pro-forma corporate filing requirement with forms that disclose transactions with related parties.  The types of transactions that are covered by this reporting relate to amounts paid or received in connection with the formation, dissolution, acquisition and disposition of the entity, including contributions to and distributions from the entity. Among the type of transactions that will require disclosure are sales, cost-sharing transaction payments, rents, royalties, leases, licenses, commissions, loans, interest, etc.

The penalty for failure to file when due and in the manner prescribed by the IRS or even the failure to maintain records as required under the law is $10,000. If a taxpayer is notified by the IRS of a failure to file and the failure continues for more than 90 days after notification by the IRS, an additional penalty of $10,000 will apply.


  • Obtain a U.S. tax identification number for the company;
  • File IRS Form 5472 by April 17;
  • Maintain the appropriate records in order to comply with the requirements. Such records must be permanent, accurate, and complete, and must clearly establish income, deductions, and credits.


Scenario 1: A U.S. Single Member LLC, owned by a foreign individual, holds rental U.S. real estate. In addition to filing his personal tax return, the taxpayer will now have an entity filing requirement to report specific transactions.

Scenario 2: A U.S. Single Member LLC, owned by a foreign corporation, holds U.S. real estate for investment purposes (i.e., not rented).  Previously, neither the foreign corporation nor the Single Member LLC had U.S. tax filing requirements until disposal of the real estate. Under the new rules, the Single Member LLC has a filing requirement every year to report the above specified transactions.

Scenario 3: A U.S. Single Member LLC, owned by a foreign corporation, holds U.S. real estate and rents the property. Previously, the foreign corporation had a corporate filing requirement with related IRS Form 5472, if applicable. Under the new rules, the foreign corporation is still required to file a corporate tax return and a related IRS Form 5472, if applicable.  However, the Single Member LLC also has an entity filing requirement with disclosure of related party transactions on IRS Form 5472 that may be much more comprehensive than what required to be disclosed by the foreign corporation.
