There are many good Civil War groups that deserve financial support, probably some in your hometown or county. Today is the last day to make a tax-deductible donation to them in 2012.

If they qualify as a 501-C3 nonprofit organization, your donation should qualify as tax-deductible when you file your 2012 tax returns. If a tax deduction isn’t important, then Tuesday or any time in 2013 would be appropriate.

For those who want to make a donation and get the benefit of it come tax season, check out the group to make sure the great majority of its funds go to preservation efforts and not staff or business expenses. Many have posted such financial information on line.

Always a safe bet is the Civil War Trust, the country’s largest nonprofit battlefield organization with more than 50,000 members. Its Web site is extensive and includes its audited financial statement, as well as information on the 34,000 acres of Civil War battlefield land the group has helped preserve since its founding in 1987.

Earlier this month, the Trust announced that it had received a 2012 Top-Rated Award from GreatNonprofits as well as the Better Business Bureau Seal of Accreditation.
