Alabama Tax Tribunal: Regulation Limiting Credit for Tax Paid to Other States Invalid
Alabama residents who paid taxes to other states and whose credits were limited by the invalid regulation may have a refund opportunity going back to 2013.
By Jeff Weinkle, SALT manager
All states that assess a personal income tax provide some kind of credit or adjustment to residents for the tax they have paid on their income to other states. Since residents are typically taxed on their entire net income in their home state, this credit prevents them from being taxed twice on the same item of income.
Beginning with the 2013 tax year, Alabama added a regulation addressing how the state’s credit for taxes paid to other states should be calculated by residents.  In an Alabama Tax Tribunal ruling issued on Sept. 29, 2016, the Tribunal determined that this new regulation was invalid since it constructed a limitation that was not provided for in the actual tax statute passed by the Alabama legislature. 
Under the existing tax statute, a resident’s credit is limited to the lower of the actual tax paid to the other state or the tax that would be due on the income taxed by the other state by applying Alabama rates.  The regulation on this statute instructs that the limiting amount of Alabama tax that would have been due on such income should be computed by multiplying the total Alabama tax calculated on all income by a fraction of the non-Alabama source income over total income. 
This calculation is different from the method used by other states, such as Georgia, which compute the resident state tax that would have been due by applying the resident state tax rate against the actual income taxed by the other state.  In using the fraction limitation, Alabama’s method could result in a lower credit and thus greater overall tax due in cases where the other state does not provide for the same deductions and exclusions as Alabama.
In its ruling, the Tribunal concluded that the regulation went beyond the plain meaning of the statute in applying this additional limitation and effectively imposes double taxation on some resident taxpayers. Since the original credit statute does not express the intent to create such a rule, the Department of Revenue goes beyond its authority to interpret the statute by regulating this additional limitation.
As a result of this ruling, Alabama residents who paid taxes to other states and whose credits were limited by the “non-Alabama source income” percentage described in the invalid regulation may have an opportunity for refund going back to the 2013 tax year.
