Most families settle their giving in December, one tax year at a time. Generosity runs on a longer clock than that. Here is how to think about thirty years of giving in three decades, what Scripture says about planning ahead, and a one-page plan you can start this quarter.

Most generosity in America already happens without a tax deduction: the rent covered for a friend, the neighbor's medical fundraiser, the check that never gets a receipt. Scripture never mentions the deduction at all. What it does talk about, again and again, is the motive behind the gift.

In 2018 the country ran an accidental experiment on whether the tax code makes people generous. Giving fell by about $20 billion — except at churches, where it barely moved. The 2026 rules shrink the deduction again, and that old result is worth sitting with before you decide what to give.
