Iceland has several tax agreements with other countries. Natural persons permanently resident and subject to full and unlimited tax in one of the Contracting States may be entitled, in accordance with the provisions of the respective conventions, to an exemption/reduction from the taxation of income and capital, without which income would otherwise be subject to double taxation. Each agreement is different and it is therefore necessary to review the agreement in question in order to determine where the tax debt of the person concerned really lies and what taxes the agreement provides. The provisions of tax agreements with other countries may result in a restriction of Icelandic tax legislation. In principle, U.S. citizens are taxable on their global income, wherever they live. However, some measures mitigate the resulting double taxation obligation.  Some investments with a flow-through or passe-through structure, such as for example. B master limited partnerships, are popular because they avoid the double taxation syndrome.
4. In the event of a tax dispute, agreements may provide a two-way consultation mechanism and resolve current issues. Double taxation is the levying of taxes by two or more laws on the same income (in the case of income tax), on wealth (in the case of capital taxes) or on financial transactions (in the case of turnover taxes). Countries can reduce or avoid double taxation by granting either a tax exemption (MS) of income from foreign sources or a foreign tax credit (FTC) for taxes on foreign income. Double taxation is achieved when the same transaction or source of income is subject to two or more tax authorities. This can be done within a single country if independent government entities have the power to tax a transaction or source of income, or can lead different sovereign states to levy separate taxes, in which case it is called international double taxation. The problem of double taxation is due to the fact that tax jurisdictions do not follow a common principle of taxation. A tax country may tax income at source, while other income is taxable on the basis of the residence or nationality of the beneficiary. .
