This form allows a foreign partner in a partnership to certify specific financial details to help lower or remove the amount of IRS withholding tax (the 1446 tax) taken out on their income. By filing Form 8804C, the partner confirms that their investment is their only activity generating this taxable income, provided the estimated tax is under $1,000.
A foreign partner must use Form 8804C to provide a certification to a partnership. This action allows the partnership to reduce or eliminate the 1446 tax it must withhold and pay on ECTI allocable to that foreign partner.
Part I collects basic identifying information, including the foreign partner's name, address, and identifying number, along with the partnership's EIN. Part II allows the foreign partner to list the amounts and character of eligible deductions and losses available to offset their allocable share of ECTI.
The certificate must be submitted to the partnership by July 23, 2012 (a specific date mentioned), or one year after the due date set forth in section 6072(c) for filing such return. For updated certificates, submission must occur within 10 days of the tax return's filing.
The instructions do not specify a single service center address for mailing; rather, it requires submitting the form to the partnership itself. The form can also be attached to IRS Form 8813 or Form 8805 when those are being filed.
First, complete Part I entirely, ensuring all applicable questions are answered and providing your full name, address, and identifying number. If certifying deductions/losses, complete Part II accurately (or Part III if applicable). Finally, sign and date Part IV; if signed by a representative, attach the power of attorney.
If errors occur, such as failing to answer questions completely, the Form 8804C may not be accepted by the partnership. Furthermore, if a lower-tier partnership relies on this certificate, insufficient information could prevent the IRS from reliably associating the ECTI and Form 8804C with the foreign partner.
A foreign partner must use Form 8804-C to provide a certification to a partnership under Regulations section 1.1446-6 to reduce or eliminate the 1446 tax on their allocable share of ECTI. Check Part I, Item B for confirmation that the filer is a foreign partner.
