Did a Guam tax adjustment reported to California trigger the historical six-month refund-claim period for changes by the IRS or another competent authority?

Plain-English summary

California Legal Ruling 346 held that an adjustment by Guam's Commissioner of Revenue and Taxation did not trigger California's historical six-month refund-claim extension.

The phrase "other competent authority" covered authorities able to change returns filed with the United States Treasury Department. Guam's commissioner changed a separate Guam return, not a U.S. Treasury return.

Reporting the Guam adjustment to FTB therefore did not activate the special six-month period under former section 19053.6.

How the historical extension worked

Former section 18451 required a taxpayer to report a change or correction by the Commissioner of Internal Revenue or another competent authority.

When the taxpayer reported such a qualifying change, former section 19053.6 allowed a refund claim based on that change within six months after the report.

The ruling read "other competent authority" through section 18451 and limited it to persons or entities authorized to change tax returns filed with the U.S. Treasury Department.

Why Guam did not qualify

The ruling cited Guam law requiring Guam income-tax returns to be filed with the territory's own Commissioner of Revenue and Taxation.

It also cited Guam law treating the taxes remitted with those returns as Guam's exclusive funds.

Because the Guam commissioner was changing a Guam return under that separate system, FTB concluded the commissioner was not an "other competent authority" for the California federal-change provision.

Result for the refund claim

The taxpayer could not rely on the Guam adjustment and subsequent California report to obtain the special six-month limitations period.

The ruling decided only that extension issue. It did not state that no refund claim could ever be filed under another timely California provision.

What this means for you

Taxpayers reporting non-IRS changes

Under the historical ruling, not every outside tax-agency adjustment counted as a federal competent-authority change. The nature of the return and the authority changing it mattered.

Guam taxpayers

A Guam adjustment did not receive the same limitations treatment as an IRS adjustment under the provisions addressed by the ruling.

Legal ruling 346

STATE OF CALIFORNIA
Franchise Tax Board - Legal Division

December 14, 1970

Statute of Limitations - Refund Claims

The words "other competent authority" contained in Revenue and Taxation Code Section 19053.6 do not include such non-federal authority as the Guam Commissioner of Revenue and Taxation. An adjustment by that department to a Guam income tax return thereafter reported to California thus does not activate the special provisions of that section extending the statute of limitations for filing refund claims.

Advice has been requested as to whether an adjustment to a Guam income tax return by the Commissioner of Revenue and Taxation of that Territory and thereafter reported to California is considered to be made by "other competent authority" within the meaning of Section 19053.6 of the Revenue and Taxation Code so as to extend thereunder the limitations period for filing certain refund claims.

If a taxpayer is required by Section 18451 to report to the Franchise Tax Board "a change or correction by the Commissioner of Internal Revenue . . . or other competent authority" and so reports such change then he may, under Section 19053.6, file a claim for refund based on this change within six months from the date it was reported. Section 18451, governing the meaning of the words "other competent authority" contained in Section 19053.6, restricts that language to persons or entities with the authority to change only those tax returns filed with the "United States Treasury Department."

Section 19513.01 of the Guam Government Code requires that Guam income tax returns be filed with that Territory's Commissioner of Revenue and Taxation and its Section 19501.04 provides that tax revenues remitted with those returns are the exclusive funds of Guam. Accordingly, a change made to a Guam return by its commissioner is not made by "other competent authority" for Section 18451 purposes and Section 19053.6 would not be applicable to extend the statute of limitations for filing a refund claim based upon such a change.
