“(a) In General.—
Except as provided in subsection (b), nothing in the laws of the United States shall prevent Guam, American Samoa, or the Northern Mariana Islands from enacting tax laws (which shall apply in lieu of the mirror system) with respect to income—
“(1) from sources within, or effectively connected with the conduct of a trade or business within, any such possession, or
“(2) received or accrued by any resident of such possession.
“(b) Agreements To Alleviate Certain Problems Relating to Tax Administration.—
Subsection (a) shall apply to Guam, American Samoa, or the Northern Mariana Islands only if (and so long as) an implementing agreement is in effect between the United States and such possession with respect to—
“(1) the elimination of double taxation involving taxation by such possession and taxation by the United States,
“(2) the establishment of rules under which the evasion or avoidance of United States income tax shall not be permitted or facilitated by such possession,
“(3) the exchange of information between such possession and the United States for purposes of tax administration, and

Any such implementing agreement shall be executed on behalf of the United States by the Secretary of the Treasury after consultation with the Secretary of the Interior.
“(c) Revenues Not To Decrease.—
The total amount of the revenue received by any possession referred to in subsection (a) pursuant to its tax laws during the implementation year and each of the 4 fiscal years thereafter shall not be less than the revenue (adjusted for inflation) which was received by such possession pursuant to tax laws for its last fiscal year before the implementation year.
“(d) Nondiscriminatory Treatment Required.—
Nothing in any tax law of a possession referred to in subsection (a) may discriminate against any United States person or any resident (corporate or otherwise) of any other possession.
“(e) Enforcement.—
“(1) In general.—
If the Secretary of the Treasury (after consultation with the Secretary of the Interior) determines that any possession has failed to comply with subsection (c) or (d), the Secretary of the Treasury shall so notify the Governor of such possession in writing. If such possession does not comply with subsection (c) or (d) (as the case may be) within 90 days of such notification, the Secretary of the Treasury shall notify the Congress of such noncompliance. Unless the Congress by law provides otherwise, the mirror system of taxation shall be reinstated in such possession and shall be in full force and effect for taxable years beginning after such notification to the Congress.
“(2) Special rule for revenue requirements.—
If the failure to comply with subsection (c) is for good cause and does not jeopardize the fiscal integrity of the possession, the Secretary may waive the requirements of subsection (c) for such period as he determines appropriate.
“(f) Definitions and Special Rules.—
“(1) Implementation year.—
For purposes of this section, the term “implementation year” means the 1st fiscal year of the possession in which the tax laws authorized by subsection (a) take effect.
“(2) Mirror system.—
For purposes of this section, the mirror system of taxation consists of the provisions of law (in effect on the day before the date of the enactment of this Act [Oct. 22, 1986]) which make the provisions of the income tax laws of the United States (as in effect from time to time) in effect in a possession of the United States.
“(3) Special rule for northern mariana islands.—
Notwithstanding the provisions of the last clause of section 601(a) of Public Law 94–241 [48 U.S.C. 1801 note], the Commonwealth of the Northern Mariana Islands may elect to continue its mirror system of taxation without regard to whether Guam enacts tax laws under the authority provided in subsection (a).”
