E0F8-O025-012101p3 Instructions for Idaho Form ID K-1 GENERAL INSTRUCTIONS Form ID K-1 is used to provide the partner, shareholder, or beneficiary of a pass-through entity (PTE) with information required to complete the pass-through owner’s (PTO’s) Idaho income tax return. Form ID K-1 isn't intended to be a substitute for the federal Schedule K-1 . The information reported on the Form ID K-1 relates to Idaho law and identifies Idaho adjustments, allocation and apportionment amounts, credits, andrecapture amounts. Items that are included on federal Schedule K-1, such as the Section 179 deduction, aren't shown on the ID K-1 as most amounts required on the Form ID K-1 aren't found on the federal Schedule K-1 . A copy of each PTO's federal Schedule K-1 and Form ID K-1 must be included with the PTE's Idaho tax return filed by: ● Every partnership or S corporation transacting business in Idaho ● Every estate or trust required to file an Idaho income tax return A copy of the Form ID K-1 must be provided to each PTO. If the PTE has withheld income tax, the PTO should include Form ID K-1 with the PTO's income tax return; otherwise, the PTO should keep it for his records. Reporting of Pass-Through Items by Individual PTOs Idaho part-year resident and nonresident individuals need to modify the amounts reported on the Form ID K-1 before entering them on their Idaho individual income tax returns. A nonresident uses the Idaho apportionment factor to determine how much of his share of income and deduction from the PTE is from an Idaho source. A part-year resident is considered to have earned the income from a PTE ratably during the tax year. For the portion of the year that the PTO was a nonresident, he will use the Idaho apportionment factor to determine how much of his share of income and deductions considered earned during that time is from an Idaho source. For the portion of the year he is a resident of Idaho, he must report all the Idaho income and deductions considered earned during that portion of the year. A resident of Idaho will be taxed by Idaho on his entire share of the income from the PTE even if the income is apportioned between Idaho and other states. Qualified Investment Partnerships Special rules apply to a PTO who is a nonresident individual when the PTE is a qualified investment partnership under Idaho law. A qualified investment partnership is an entity classified asa partnership for federal income tax purposes and isn’t a publicly traded partnership taxed as a corporation, with at least 90% of its gross income from investments whose income wouldn’t be taxed by Idaho if received directly by a nonresident individual. Noninvestment income from an Idaho source is subject to Idaho tax. If the PTE is a qualified investment partnership, include a statement on Form ID K-1, Part E, Supplemental Information that the PTE is a qualified investment partnership and that anonresident may not be taxed on certain investment income. SPECIFIC INSTRUCTIONS All amounts on the Form ID K-1 should be included before applying the Idaho apportionment factor of the PTE. A PTO whois a nonresident individual will apply the Idaho apportionment factor in computing the amounts to include on his Idaho individual income tax return. HEADING AND QUESTIONS Tax Year File the 2011 form for calendar year 2011 or a fiscal year that begins in 2011. If the PTE’s tax year is a fiscal year, fill in the tax year space at the top of the form. Final Return and Amended Return If this is the last year the PTE is filing an Idaho income tax return or if the PTE is filing an amended Idaho return, check the applicable box at the top of the form. Identification Numbers, Name and Address Write the PTE’s federal employer identification number (EIN), business name, and address in the spaces provided. Write the PTO’s social security number or EIN, name, and address in the spaces provided. If the PTO is treated as a disregarded entity
