Any fiduciary who is required to file an income tax return in another state, and who receives changes made by such state in the fiduciary's state income tax return which are material to the tax liability owed to this state or to the amount of distributable income attributable to Nebraska must report the changes to the Nebraska Department of Revenue within ninety days of the final determination of the change. Reportable changes include changes made to the state's return by any competent authority of the state. In reporting any change to the other state's tax return, the fiduciary must furnish the department complete information regarding the amount of income reported and taxes paid to the other state. The report must also concede the accuracy of the final determination or give a statement outlining the specific errors of the final determination.
Any adjustments made by the other state's amended returns or by the other state's revenue service must be reported to the department by filing an amended Nebraska Fiduciary Income Tax Return for the taxable year involved. The amended return for Nebraska must be filed within ninety days of the filing of the amended return for the other state, and must include copies of any reports issued by state authorities. A fiduciary who files an amended return with the other state as a protective claim is not required to file an amended return with Nebraska. The acceptance of the claim, or the payment of the refund, constitutes a state change that must be reported. A protective claim is a claim filed to protect the taxpayer from the expiration of the statute of limitations while a separate action challenging a position of the other state is pending.
The amended return for Nebraska must be filed separately and should not be attached to or filed with a return for another taxable year. Payment of any additional tax must accompany the amended return.
For the purpose of determining when adjustments in state income tax constitute a final determination, the following acts will be considered to be a final determination even though the taxpayer and the other state may still be contesting the amount due:
If a fiduciary fails to file an amended return reporting any change or correction which increases its Nebraska taxable income, tax liability, or distributable income, the department may mail a notice of deficiency to the fiduciary at any time. If a fiduciary properly reports any change in the other state's taxable income, tax liability, or distributable income, the department may make an assessment relating to the change at any time within two years after the amended return was filed.
Any change in the other state's adjusted taxable income, tax liability, or distributable income which has not been reported to the other state cannot be used as the basis for a change or reduction in the Nebraska liability.
The amended return reporting a change that results in an overpayment of tax for Nebraska is a claim for credit or refund.
