OH HB355

Allows taxpayers to contribute any portion of their income tax refund (under existing law) or increase their tax payment to any state fund established in the state treasury, effective for tax years beginning in 2011 or thereafter.

Permits taxpayers to designate which state fund receives the contribution or specify the purpose for which funds should be used; if purpose is designated but no fund is specified, the tax commissioner determines the appropriate fund to receive the contribution.

Requires a minimum contribution of one dollar and specifies that contributions from increased tax payments that are not fully remitted will be reduced accordingly; contributions cannot reduce the combined state and school district income taxes owed.

Maintains existing provisions allowing contributions to three specific funds (natural areas and preserves fund, nongame and endangered wildlife fund, and military injury relief fund) while expanding the system to any state fund.

Establishes administrative cost-sharing mechanism where one-fourth of system administration costs are deducted from contributions to the three named funds and other state funds proportionally, with costs capped at 2.5 percent of total annual contributions.
