Every July, between €700M and €800M in tax refunds for donations land back in the taxpayer's account and dissolve into everyday spending before becoming the next donation. Redona closes that leak with a single checkbox.
A new checkbox on the tax return: "Would you like your donation refund transferred directly to the beneficiary organizations instead of your account?" The taxpayer checks it once; it's revocable at any time.
The Tax Agency had already decided to refund that amount. Box 723 doesn't change the sum, only the recipient of the transfer — from the donor's account to the NGO's, in the same proportion as the original donations.
The mechanism activates at the peak liquidity moment for Spanish households: the annual tax season, culminating on July 2nd.
The box is checked at the moment of highest generous intent — when declaring the donation — not months later, once the refund has blended with other income.
Illustrative example based on current deduction brackets. Not a substitute for tax advice.
| Refund via Box 723 | — |
|---|---|
| Real cost to the donor | — |
| Compound effect (×2.9, 3 cycles) | — |
The same precommitment principle adapts to other fundraising contexts: Donalizar, Viaje Semilla, Matching Seed, WallaDona and Teaming Five are variants of the Magic Box applied to charity events, crowdfunding and the sharing economy.
