Since state tax treatment of 529 Plans varies, one of the many
important factors to consider when selecting a 529 Plan is whether a state offers
a tax deduction or credit for contributions to that state's own plan. This
calculator allows you to compare contributions made to an in-state 529 Plan that
offers a tax deduction or credit to contributions made to an out-of-state 529 Plan
where the deduction or credit does not apply, thus illustrating the effectiveness
of the tax benefit relative to potential plan performance.
