Form 1042 for LLCs

Form 1042 is the IRS annual return for US payers that paid US-source income to non-residents. Your Wyoming LLC files Form 1042 only if it paid US-source income (royalties, dividends, interest) to foreign persons during the year.

Answer

Form 1042 is the annual return for US payers that paid US-source income to non-residents during the year. Most non-resident Wyoming LLC operators do NOT file Form 1042 because their LLC pays customers and vendors, not US-source FDAP to other non-residents. Form 1042 is triggered when you make royalty payments to foreign licensors, pay US-source dividends to non-resident shareholders, or otherwise pay US-source FDAP that requires 30% (or treaty rate) withholding. Due March 15 of the following year.

When your LLC files Form 1042

  • Your LLC paid royalty income to a foreign licensor
  • Your LLC paid interest on a loan to a foreign lender
  • Your LLC paid dividends to a foreign shareholder (rare for LLCs)
  • Your LLC made other US-source FDAP payments to non-residents

When your LLC does NOT file Form 1042

  • You pay customers (you receive money from customers, you do not pay them)
  • You pay US vendors (vendors are US persons; 1042 is for non-resident recipients)
  • You pay foreign vendors for services performed outside the US (not US-source)
  • You pay foreign vendors for goods (goods are not FDAP)

Form 1042 vs Form 1042-S

Form 1042 is the LLC's annual summary return. Form 1042-S is the per-recipient detail form (similar to a 1099). The LLC sends 1042-S to each non-resident recipient AND to the IRS. Form 1042 summarizes all 1042-S filings.
