When you file your state taxes this year, the Vermont Children's Trust Foundation hopes you'll add a few dollars to line 29B. That's the line item for the Children's Trust Fund, a pool of money managed by the nonprofit VCTF. The fund supports community-based prevention efforts, including after-school, literacy and mentoring programs. Vermont organizations receive roughly $450,000 each year — about $75,000 of which comes from the tax checkoff. A note on the VCTF website urges Vermonters to give at least a dollar this way. "If we reach our goal, we will quadruple the amount given in previous years through the tax checkoff," reads the VCTF's site. That would enable the fund "to make grants to at least 15 more programs than we were able to help last year." C'mon, what's an extra dollar compared with all that cash you're already dropping on property taxes?
