EXAMPLE: Taxpayer purchases $400,000 worth of qualifying section 179 assets and places all of them in service in 2018. Taxpayer claims a section 179 deduction of $400,000 for the full cost of the assets on the 2018 federal return. The Iowa section 179 deduction for 2018 is phased out dollar for dollar by the amount of section 179 assets placed in service in excess of $280,000. This means that, for 2018, the Iowa deduction is fully phased out if the taxpayer placed in service section 179 assets that cost, in total, more than $350,000. Since the cost of the qualifying assets in this example exceeds the Iowa section 179 phase-out limit, the taxpayer cannot claim any section 179 deduction on the Iowa return. However, the taxpayer may depreciate the entire cost of the assets for Iowa purposes.
EXAMPLE: Taxpayer purchases a $100,000 piece of equipment and places it in service in 2018. Taxpayer claims a section 179 deduction of $100,000 for the full cost of the equipment on the 2018 federal return. Taxpayer is also required to claim a section 179 deduction of $70,000 on the 2018 Iowa return (the full amount of the federal deduction up to the Iowa limit). The taxpayer can depreciate the remaining $30,000 cost of the equipment for Iowa purposes.
EXAMPLE: Partner A (an individual and an Iowa resident) owns 50 percent interests in each of three partnerships: C, D, and E. Partnership C does business exclusively in Iowa, places $200,000 worth of section 179 assets in service during tax year 2019 and claims a federal section 179 deduction for the full cost of the assets. Because C is required to file an Iowa partnership return, C is subject to the Iowa section 179 limitations for 2019 and must adjust its Iowa section 179 deduction as provided in 302.65(2)"e" (1) "1." C passes 50 percent of its section 179 deduction ($100,000 for federal purposes, $50,000 for Iowa purposes) through to A. A also receives $50,000 each in section 179 deductions from D and E, for a total of $150,000 in section 179 deductions (for Iowa purposes) in 2019. A is subject to the $100,000 Iowa section 179 deduction limitation for 2019, but because A received total section 179 deductions from one or more pass-throughs in excess of the 2019 Iowa limitation, A is eligible for the special election referenced in 302.65(2)"e" (1) "2."
EXAMPLE: Taxpayer purchases a $100,000 piece of equipment and places it in service in 2019. Taxpayer claims a section 179 deduction of $100,000 for the full cost of the equipment on the 2019 federal return. Taxpayer is also required to claim a section 179 deduction of $100,000 on the 2019 Iowa return (because the federal deduction is equal to the Iowa limit for the year, the Iowa and federal deductions are the same). However, the taxpayer has only $50,000 in business income for 2019, so the allowable deduction for that year is limited to $50,000. The remaining $50,000 may be carried forward and applied as a section 179 deduction (subject to all limitations) in 2020, and in any future years until the amount is fully deducted.
EXAMPLE: A is a sole proprietor who places in service $20,000 worth of section 179 assets in tax year 2018 and claims the deduction for the full amount for federal purposes. A is also a partner in Partnership B, an out-of-state partnership with no Iowa filing obligation. Partnership B also places section 179 assets in service, properly claims a federal section 179 deduction, and passes a total of $100,000 of that deduction through to A. For federal purposes, A has a total of $120,000 in section 179 deductions. Because A has section 179 deductions from a pass-through that exceed the Iowa limitation for the year, A is eligible for the special election. A makes the special election and claims the maximum Iowa section 179 deduction of $70,000 on the amount passed through from Partnership B. Under the special election, A will be allowed to deduct the remaining $30,000 passed through from Partnership B over the next five years, as described in paragraph 302.65(3)"e." However, because A made the special election, A will be required to depreciate the entire $20,000 cost of the assets A placed in service as a sole proprietor.
EXAMPLE: A is an Iowa resident who is a partner in a partnership that does not do business in Iowa. In 2019, the partnership passes through a $600,000 federal section 179 deduction and does not recalculate the deduction for Iowa purposes, because the partnership has no obligation to file an Iowa return. A claims an Iowa section 179 deduction of $100,000 (the 2019 Iowa limitation) and elects the five-year carryforward for the rest, meaning A will be allowed to take a $100,000 Iowa deduction in each of the next five years.
In 2020, A is eligible for the $100,000 deduction carried forward under the election, but A only has $50,000 in business income. The deduction is limited to business income, so A can only use $50,000 of the deduction in this year. However, A will be permitted to treat the excess $50,000 as a section 179 carryforward and use it to offset business income in future years until the deduction is used up.
This rule is intended to implement Iowa Code section 422.7 as amended by 2019 Iowa Acts, Senate File 220.
