I assume you are the sole member of the LLC. As an initial matter, an LLC with only one owner is a disregarded entity by default for US federal income tax purposes unless an election is made to treat it as a corporation. Other countries could have varying views on whether the LLC is disregarded or considered a corporation. I will consider first the case of a disregarded LLC and then one treated as a corporation.If the LLC is disregarded, you will be considered the person earning the income from its business. In that case you will calculate your taxable income in accordance with the laws of each country in which the LLC does business. You will also calculate your income from is business under US tax rules for US income tax purposes. You may either deduct any foreign taxes paid or claim them as a foreign tax credit on your personal income tax return.Depending on your state of residence, this income could also be subject to state income tax. States generally follow the federal rules in calculating taxable income, but often with a number of adjustments - both additions to and subtractions from - federal taxable income to arrive at state taxable income. This amount is then allocated and apportioned to the state according the to formula used by that state. I might be corrected on this by a state tax expert, but I believe that income not apportioned to another state may be includible in the tax base of the state of residence of the person earning it. Since the income is earned outside the US, it is not allocable or apportionable to any US state and hence would be taxed in your state of residence.If the LLC is a corporation, the same rules apply, only its income generally is taxed initially at the LLC level only in the manner described above. You will not personally pay any tax on the income until such time that it is distributed to you in the form of a dividend. There is a tax on the accumulated earnings of corporations that prevent corporations from building up earnings without distributing them so as to avoid the second level of tax on shareholders, but Iu2019m not aware of how often, or successfully, the IRS has deployed this tool in the last 30 years. The LLC would be taxable in its state of domicile, generally where its headquarters is located, on its entire income in the manner described above.
