US Business Tax Returns partnerships, multi-member LLCs and sole proprietors

US pass-through businesses do not usually pay federal income tax themselves; their profits flow to the owners. But they still file returns, issue K-1s and, where partners are foreign, may have to withhold tax. We prepare Form 1065 partnership returns, Schedule C for sole proprietors and the related forms for US businesses with owners in Pakistan and elsewhere.

US business returns

No entity tax does not mean no filing

Partnerships and multi-member LLCs taxed as partnerships pass their income to the owners, who pay the tax on their own returns. The business still files an information return, issues K-1s to every partner and, where a partner is foreign, may have to pay withholding tax on their share.

A US partnership, including a multi-member LLC that has not elected corporate treatment, files Form 1065 by the 15th day of the third month after its year end, which is 15 March for a calendar-year business, with a six-month extension available on Form 7004. Each partner receives a Schedule K-1 showing their share of income, deductions and credits, which they report on their own return. Late filing penalties are charged per partner, per month, so even small partnerships can face significant penalties.

Foreign partners create additional obligations. Under section 1446, a partnership with income effectively connected with a US trade or business must withhold tax on the share allocated to foreign partners and file Forms 8804 and 8805. The foreign partner then files a US non-resident return to report the income and claim credit for the withholding. Sole proprietors, including single-member LLCs owned by US persons, report business income on Schedule C of Form 1040 and pay self-employment tax; single-member LLCs owned by foreign persons have their own reporting requirements, covered on our LLC page.

We prepare the partnership return from your books, calculate each partner's share under the partnership agreement, issue K-1s, handle foreign partner withholding and coordinate with state filings. For owners in Pakistan, we also consider how the US income is taxed in Pakistan, using the double tax treaty and foreign tax credits, and report it in the Pakistani return.

For corporations, see US corporate tax returns; for foreign-owned single-member LLCs, US LLC tax services; and for state obligations, US state tax filing.

Partnership penalties are charged per partner per month. A two-partner LLC that files three months late can already owe a meaningful amount.

By the 15th day of the third month after the year end, which is 15 March for calendar-year partnerships, with a six-month extension available on Form 7004.
What is a Schedule K-1?
A form issued to each partner showing their share of the partnership's income, deductions and credits, used to prepare their own return.
What if a partner lives in Pakistan?
The partnership may need to withhold tax on the foreign partner's share of effectively connected income under section 1446, and the partner files a US non-resident return.
How are sole proprietors taxed?
Business income is reported on Schedule C of Form 1040 and subject to income tax and self-employment tax.
What about a single-member LLC owned from Pakistan?
It is usually disregarded for income tax but must file Form 5472 with a pro forma Form 1120. See US LLC tax services.
