If you’ve ever had income from a partnership with foreign partners involved, there’s a good chance you’ve either come across Form 8805 or you will eventually. While it might sound like something that only applies to nonresidents, U.S. citizens can be affected by this form too—especially if you’re part of a partnership that has some international ties.
Do you have foreign business partners? Are you unsure of how to report and pay taxes on them? Don’t worry, Form 8805 has you covered. This form is a key component of partnership withholding, a process that ensures your business pays the appropriate amount in taxes for its foreign partners. With this guide, learn all about Form 8805: what it is, who should file it, and how to complete it. So let’s get started – opening up this window into the world of international taxation!
What Is Partnership Withholding?
Partnership withholding is a process that requires US businesses with foreign partners to withhold taxes on any income effectively connected to a US business or trade. This withholding tax applies regardless of whether the partnership ever makes any cash distributions to the foreign partner and even if the foreign partner’s ultimate US tax liability is zero. The IRS Form 8805 is used to report this withholding, which ensures that both the partnership and its partners are compliant with federal tax laws.
It provides an annual summary statement of what was withheld from the foreign partner’s share of income and allows for certain credits such as a tax credit allocable to nonresident aliens. Completing this form correctly is key to avoiding large penalties, so it’s important for partnerships to make sure they understand all filing requirements before submitting their tax returns.
Form 8805 is a tax form issued by the Internal Revenue Service (IRS) for US businesses with foreign partners. It is used to report the amount of income effectively connected to a US business or trade that has been allocated to a foreign partner, and any withholding taxes paid. The partnership must complete this form and send it to all foreign partners involved, even if no withholding tax is required.
If there is a withholding tax, the foreign partner can claim credit for their share of income that was withheld when they file their individual US tax return. Completing Form 8805 correctly is essential in order to avoid large penalties, so it’s important for partnerships to make sure they understand all filing requirements before submitting their tax returns.

If you’re on the receiving end of this form, it typically means you’re considered a foreign partner, or your role in the partnership has been structured that way for tax reasons. This could happen even if you live in the U.S. but hold certain types of investments in partnerships that involve international individuals or entities. In other words, the form isn’t just for people living overseas—it can impact a broader group than most people expect.
About Form 8805 and Effectively Connected Taxable Income
Form 8805 is an Internal Revenue Service (IRS) tax form used to show the amount of effectively connected taxable income (ECTI) and the total tax credit allocable to a foreign partner for the partnership’s tax year. This form is issued for US businesses with foreign partners and requires them to report any withholding taxes paid on allocated income. It’s important for partnerships to accurately complete Form 8805, as failing to do so can lead to hefty penalties from the IRS.
Partners should also make sure they understand all filing requirements before submitting their taxes, as non-compliance with them could result in additional penalties or fines. Once completed, the form should be sent to all foreign partners involved, even if no withholding tax is required. The foreign partner can then use it when filing their individual US tax return in order to claim credit for their share of the withheld income.
Who Should File Form 8805?
Form 8805 must be filed by US businesses with foreign partners in order to report any withholding taxes paid on allocated income. This form is especially important for partnerships that have nonresident aliens as shareholders, as they are required to pay US tax on their share of income from the partnership. Additionally, Form 8805 must also be filled out by any business that has an obligation to withhold or collect taxes from foreign partners.
It is highly recommended that all partnerships review their filing requirements before submitting their taxes in order to avoid any penalties or fines. Partners should also make sure to send a copy of the completed Form 8805 to each foreign partner involved regardless of whether or not withholding tax is required, as this will allow them to claim credit for their share of the withheld income when filing their individual US tax return.

When Should You File Form 8805?
This form usually shows up after the end of the tax year, typically in the first quarter of the next calendar year. The partnership has to file Form 8805 along with Form 8804 (which summarizes all the withholding), and they’re due by the 15th day of the third month following the close of the partnership’s tax year. If your partnership follows the calendar year, that would be March 15.
You’ll usually receive your copy of Form 8805 sometime around tax season, and you’ll need to use it when you file your individual or corporate return, depending on your filing situation. If you’re receiving one, it’s proof that tax was already withheld on your share of partnership income.
How Does Form 8805 Affect Your Taxes?
Form 8805 functions kind of like a 1099 or W-2 in that it documents income and tax withheld. If you’re a foreign partner, it helps you claim the withheld amount as a credit against your total U.S. tax liability. Even if you end up owing no additional tax, filing the form is how you reconcile that withholding with your actual return.
If you’re a U.S. citizen and somehow classified as a foreign partner through a tax election or due to ownership through a foreign entity, it’s especially important that you understand what’s being reported on the form and how it affects your personal return. In some cases, the IRS might require you to file a U.S. return just to account for this withheld tax.
Instructions for Completing Form 8805
Form 8805 is an Internal Revenue Service (IRS) tax form that is used to report income allocated to foreign partners. This form must be completed by US businesses that have foreign partners or those with an obligation to withhold or collect taxes from foreign partners. The instructions for completing Form 8805 are simple, as the majority of the information required should already be available in the business’s books and records.
The first step is to fill out Part I, which requires basic information such as a company’s name and address, Employer Identification Number (EIN), country code, and contact information.
Part II must be completed with details about the total amount of income allocated to foreign partners (line 9), tax exemptions from this income (line 8b), and any tax credits allocable (line 10).
It is important to double-check all fields before submitting Form 8805 as any errors can result in penalties or fines from the IRS. Form 8805 is an essential form for US businesses with foreign partners, so pay close attention to the instructions on the federal tax form.

Form 8805: FAQ
1. Why did I get a Form 8805 if I live in the U.S. and pay taxes here?
You could receive Form 8805 even if you’re living and working in the U.S. if you’re involved in a partnership that treats you as a foreign partner for tax reasons. This can happen if your ownership interest is held through a foreign entity or a trust. From the IRS’s perspective, it’s about who legally holds the partnership interest, not just where you live. So even though you’re filing a regular U.S. tax return, the partnership may still be required to withhold taxes and issue this form to you.
2. What do I need to do if I get a Form 8805?
If you receive a Form 8805, don’t just set it aside. It’s an important part of your tax return. You’ll need to report the income and withholding shown on the form, usually on Form 1040-NR if you’re a foreign partner or on your regular return if you’re a U.S. person who received it by mistake. The withholding amount reported can often be used as a credit against your total tax bill. In some cases, you might get a refund if too much was withheld. It’s also a good idea to double-check the amounts listed to make sure everything lines up with your records.
3. Can I use the tax withheld on Form 8805 as a credit on my tax return?
Yes, the amount of U.S. tax withheld that’s shown on Form 8805 can be claimed as a credit on your U.S. tax return. This credit reduces the total tax you owe. If more tax was withheld than you actually owe for the year, you can generally claim a refund. Just make sure to include the form with your return and enter the numbers correctly. If you’re filing electronically, you may need to manually enter the details or attach a scanned copy, depending on your tax software.
4. What if I’m the one running the partnership—how do I handle Form 8805?
If you’re managing a partnership that includes foreign partners, you’re responsible for figuring out how much U.S. tax needs to be withheld from their share of the income and reporting that through Form 8805. You’ll also need to file a summary form called Form 8804, which combines all the individual 8805s. It’s important to keep good records and issue the forms on time, because there can be penalties for missing the deadline or making mistakes. You should also send a copy of Form 8805 to the partner and keep one for your own files.
5. Do I always need to file a tax return if I get a Form 8805?
Yes, you should file a tax return if you receive Form 8805, even if the partnership already withheld tax. This is how you report the income and reconcile the taxes that were taken out. If you don’t file, the IRS won’t have a complete picture and you might end up with issues down the road, like not getting a refund you’re owed or getting letters asking for more information. Filing a return is the best way to make sure your taxes are handled correctly and to avoid unnecessary stress.
6. Can a U.S. partnership issue multiple Form 8805s to the same partner in one year?
Yes, that can happen, and it’s actually pretty common. If the partnership does quarterly withholding or has different allocations throughout the year, it might send multiple Form 8805s to the same foreign partner. Each one will cover a specific time period or portion of income. If you get more than one, make sure you include all of them when filing your tax return. The IRS wants to see the full picture, and missing even one form could cause confusion or delay a refund.
