IN THE OREGON TAX COURT REGULAR DIVISION Corporation Excise Tax

MICROSOFT CORPORATION, a ) Washington corporation, ) ) Plaintiff, ) TC 5413 v. ) ) DEPARTMENT OF REVENUE, ) State of Oregon, ) ) ORDER ON PLAINTIFF’S MOTION Defendant. ) FOR RECONSIDERATION

This matter is before the court on Plaintiff’s motion under Tax Court Rule (TCR) 80A for

reconsideration of the court’s August 29, 2024, Order on Cross-Motions for Summary Judgment

(August 29 Order). The first part of the August 29 Order grants relief to Plaintiff to the extent of

concluding that ORS 314.665(6)(a) requires the 20 Percent Repatriation Amount to be

reincluded in the sales factor of Plaintiff’s Water’s Edge Group as a deemed dividend. 1 The

court uses the term “Post-Reinclusion Assessment” to refer to the assessment amount, as reduced

by the dilutive effect of reincluding the 20 Percent Repatriation Amount in the sales factor. The

second part of the August 29 Order rejects Plaintiff’s argument for further factor relief under

Oregon’s “safety valve” statute, ORS 314.667, concluding that Plaintiff failed to carry its burden

1 Terms used in this order have the meanings assigned in the August 29 Order.

ORDER ON PLAINTIFF’S MOTION FOR RECONSIDERATION TC 5413 Page 1 of 13 of proof that even the unreduced assessment violates either the statutory “fairly represent”

standard or constitutional standards. 2

Plaintiff now seeks reconsideration of the second part of the August 29 Order,

specifically objecting to the use of Defendant’s proffered adaptation of the “Augusta Formula”

when testing for constitutional factor relief. That adaptation essentially extends the Augusta

Formula over the nearly twenty-year period during which the CFCs accumulated the earnings

and profits that were deemed distributed in TYE 2018. The adaptation thus includes the sum of

each past year’s Oregon taxable income that would have been due under worldwide combined

reporting, an amount that the court now refers to as the Retrospective Worldwide Amount. 3 The

August 29 Order then compares the Retrospective Worldwide Amount to the assessment.

Because the Retrospective Worldwide Amount is greater than the assessment, the August 29

Order concludes that Plaintiff has not shown that either the original assessment amount or the

Post-Reinclusion Assessment Amount fails the statutory “fairly represent” standard or

constitutional standards. Plaintiff’s motion for reconsideration focuses on why the court should

apply a different version of the Augusta Formula, as described below.

Defendant objects to Plaintiff’s motion but does not itself move for reconsideration of

either part of the August 29 Order, citing the court’s rule disfavoring “[c]laims addressing legal

issues already argued in the parties’ briefs and addressed by the court.” TCR 80A A(4). But

2 The court’s references to the Oregon Revised Statutes (ORS) are to the 2015 edition. 3 Following entry of the court’s August 29, 2024, Order on Cross-Motions for Summary Judgment, the parties reached a Stipulation on Computational Issues (“Stipulation”), which was filed with the court on January 10, 2025. The court has reviewed the parties’ Stipulation, and the figures therein, and has determined that while it will result in a slightly different refund amount for Plaintiff, it does not materially change the outcome on any of the legal issues addressed in this Order or in the Amended Order on Cross-Motions for Summary Judgment. Therefore, unless otherwise noted, this Order continues to refer to the amounts before the court at the time the August 29 Order was entered.

ORDER ON PLAINTIFF’S MOTION FOR RECONSIDERATION TC 5413 Page 2 of 13 Defendant urges that, if the court were to grant Plaintiff’s motion, the court should also take up

Defendant’s argument under the first part of the August 29 Order that reinclusion of the 20

Percent Repatriation Amount is inherently distortive. (Def’s Response Reconsider at 9-10.)

In its discretion, the court will reconsider the August 29 Order as requested by Plaintiff,

even though on summary judgment the parties extensively briefed and argued their respective

positions regarding the constitutional fairness requirement on which the Augusta Formula is

based. The court is moved to address Plaintiff’s new, more targeted, arguments in the interest of

judicial economy, because of the potential that they otherwise could be raised for the first time in

a further appeal. See ORS 305.445 (scope of Supreme Court review includes “errors or

questions of law”).

Accordingly, this order will first analyze Plaintiff’s arguments for its version of the

Augusta Formula. Thereafter, this order will also address Defendant’s request, in order to clarify

the court’s reinclusion analysis. For the reasons discussed below, the court will not change its

ultimate conclusions, or any results, under either part of the August 29 Order. The court will

today, however, issue an Amended Order on Cross-Motions for Summary Judgment (Amended

Order) that restates its decision in full, with amendments to portions of its reasoning and

correction of minor errors, most of which were helpfully identified by the parties.

A. Plaintiff’s Arguments

According to Plaintiff, the Retrospective Worldwide Amount is an invalid comparator.

Instead, Plaintiff urges the court to compare the Post-Reinclusion Assessment Amount solely to

the TYE 2018 Oregon taxable income that would have been due under worldwide combined

reporting, a comparator that the court now refers to as a Single-Year Worldwide Amount.

Plaintiff reasons that Congress chose to require taxpayers to include the Federal Repatriation

ORDER ON PLAINTIFF’S MOTION FOR RECONSIDERATION TC 5413 Page 3 of 13 Amount in the tax base for a single tax year, instead of requiring taxpayers to amend their federal

income tax returns for prior years, and a fairness analysis for state apportionment purposes must

be based on that reality. The formula Plaintiff uses to derive its Single-Year Worldwide Amount

is to add the Federal Repatriation Amount to the taxable income of the Water’s-Edge Group for

TYE 2018, then to multiply that sum by a fraction, of which the numerator is Oregon sales for

TYE 2018 and the denominator is the sum of (1) sales everywhere by the Water’s-Edge Group

for TYE 2018 and (2) cumulative sales by the CFCs for TYE 2000 through 2018. (See Ptf’s Mot

Recons at 5, Table 3 (labeled in the motion as “WW Comparison”).

Plaintiff’s proffered Single-Year Worldwide Amount is less than the Post-Reinclusion

Assessment Amount. (Compare Ptf’s Mot Recons at 5, Table 3 (showing TYE 2018 Oregon

taxable income of $112,740,081 as Plaintiff’s Single-Year Worldwide Amount with Ptf’s Mot

Recons at 5, Table 2 (showing TYE 2018 Oregon Taxable Income of $163,223,673 as the court’s

Post-Reinclusion Assessment Amount pursuant to the August 29 Order).) 4 Plaintiff argues that

this fact proves “unconstitutional distortion.” (Ptf’s Mot Recons at 2.) According to Plaintiff,

the court must address this distortion by capping Oregon taxable income for TYE 2018 at the

Single-Year Worldwide Amount. (See Ptf’s Mot Recons at 6 (“Factor relief must be provided so
