Multistate Tax Alert: Oregon Tax Package Contains Corporate Tax Increases

Reduced tax rates for investors in certain pass-throughs, and favorable IC-DISC provisions



As part of a “grand bargain” involving reforms to Oregon retirement benefits, education spending, and increased tax revenues, Oregon Governor Kitzhaber recently signed House Bill 3601 (“H.B. 3601”),1 which includes the following modifications to Oregon law:

  • For tax years beginning on or after January 1, 2013, a reduced threshold (from $10 million to $1 million taxable income) for imposition of Oregon’s 7.6% corporate income and excise tax rate
  • For tax years beginning on or after January 1, 2015, reduced personal income tax rates on nonpassive income earned by partnerships and S corporations (and LLCs taxed as such) for qualifying individual taxpayers
  • Favorable tax treatment of “interest charge domestic international sales corporations,” or “IC-DISCs,” formed prior to January 1, 2014 

H.B. 3601 is by its terms effective January 1, 2014, with some provisions having retroactive application. However, the bill may be subject to public voter referendum, which could defer its actual enactment or cause the bill to not be enacted. In this Tax Alert we summarize the above-mentioned modifications2 and we discuss briefly the effective date and referendum issues.

Reduced threshold for top corporate excise and income tax rate 

Under current law, the top Oregon corporate income and excise tax rate of 7.6% applies to all Oregon taxable income in excess of $10 million.3 For tax years beginning on or after January 1, 2013, H.B. 3601 would reduce the threshold for imposition of the 7.6% rate to taxable income in excess of $1 million.4

Reduced personal income tax rates for nonpassive income earned by certain pass-throughs

Under current law, Oregon personal income taxpayers are subject to a top income bracket of 9.9% that applies to individuals (on income in excess over $125,000); and to taxpayers filing jointly, head of household, or qualifying widowers with a dependent child (on income in excess of $250,000). For tax years beginning on or after January 1, 2015, H.B. 3601 would permit personal income taxpayers to elect, irrevocably, to apply reduced tax rates on nonpassive income earned by partnerships, S corporations, and LLCs taxed as either a partnership or S corporation.5 Depending upon the level of qualified nonpassive taxable income from pass-through entities, the tax rates6 would be as follows:

Oregon pass-through taxable income Tax rate
Up to $250,000 7%
In excess of $250,000 up to $500,000 7.20%
In excess of $500,000 up to $1 million 7.60%
In excess of $1 million up to $2.5 million 8%
In excess of $2.5 up to $5 million 9%
In excess of $5 million 9.90%

Several requirements must be satisfied in order to qualify for the reduced rates, including but not limited to:

  • Income must be “nonpassive,” meaning income other than from a “passive activity” as defined in I.R.C.§ 469;
  • The electing partner must materially participate in the management of the pass-through entity;
  • The pass-through entity must employ at least one non-owner, member or limited partner; and
  • Qualifying employee(s) must perform at least 1,200 aggregate hours of work in Oregon for the passthrough entity by the close of the tax year for which the reduced rate is allowed, and work hours may be considered only for weeks in which a worker works at least 30 hours.7

IC-DISC provisions

A thorough discussion of the IC-DISC structure is beyond the scope of this Alert. Generally speaking, however, an IC-DISC is a tax-exempt corporate entity that benefits exports. A domestic C corporation requests approval from the IRS to be treated as an IC-DISC for federal tax purposes. As a result of its status as an IC-DISC, the IC-DISC pays no federal income taxes and reduces the exporter’s tax liability by effectively converting a portion of the exporter’s net export income, which is taxable at ordinary income rates as high as 39.6 percent, into qualified dividends generally taxed at 20 percent after 2012. The exporter pays a deductible commission to the IC-DISC, which pays no income tax on that commission. The IC-DISC later distributes its income to its shareholders as qualifying dividends, taxed at the reduced 20% rate for individual shareholders. Various states, including Oregon, have refused to conform to this federal treatment and often require taxpayers to disregard transactions between the taxpayer and its IC-DISC as related-party transactions. 

For IC-DISCs formed on or before January 1, 2014,8 H.B. 3601 would create special provisions, including:

  • IC-DISCs would be exempt from Oregon tax except for a 2.5% tax on commissions received
  • Commission payments to the IC-DISC would be deductible; and
  • IC-DISC dividends received by Oregon personal income taxpayers would be subtracted from federal taxable income for purposes of calculating personal taxable income.9

Effective date / Oregon’s referendum process / financial reporting effect

Although H.B. 3601 has been passed by the state legislature, signed into law by the governor, and is scheduled to become effective on January 1, 2014, the bill is not considered enacted until: (1) it is affirmatively confirmed by the state’s voter referendum process,10 or (2) upon expiration of that process without voters having timely filed a qualified referendum petition.11 Therefore, in Oregon, in addition to being signed into law by the governor (i.e., not vetoed), a law also has to survive the referendum process, or the period for such referendum process must expire, in order for the law to be considered enacted. Accordingly, H.B. 3601 is not presently considered enacted law for financial reporting purposes.


Various provisions of H.B. 3601 may provide potential opportunities for further consideration. For example:

  • Can a partnership or S corporation adjust its operations to increase its nonpassive income?
  • Are there certain actions that a taxpayer may take prior to January 1, 2014, in order to potentially derive benefit from the IC-DISC provisions?
