Single-Member LLC Tax Overview

A single-member LLC is the most popular business structure for solo entrepreneurs. By default, the IRS treats it as a disregarded entity — meaning the LLC itself does not file a separate tax return. For domestic owners, all income and expenses are reported on Schedule C of Form 1040.

For foreign owners, the tax treatment differs significantly. Foreign-owned single-member LLCs must file Form 5472 along with a pro forma Form 1120 annually, reporting all transactions between the foreign owner and the LLC. This filing is required even if the LLC had zero income.

Liability Protection and Tax Simplicity

The single-member LLC combines liability protection (separating personal and business assets) with tax simplicity. Unlike a corporation, there is no double taxation — income flows directly to the owner. Unlike a sole proprietorship, the LLC provides a legal shield for personal assets.

However, the simplicity comes with responsibilities. Self-employment tax applies to domestic owners on all LLC income, and foreign owners face specific information return requirements that carry significant penalties for non-compliance.
