Giver

Give before the money reaches the checking account. Giver extends Form 145 — the form workers already use to adjust their withholdings — to include recurring donation commitments.

The problem

The average donor finances the State for months before recovering their deduction: they give in January and don't see the tax benefit until next year's return. That lag — the Financial Death Valley — keeps recurring generosity out of reach for anyone who can't afford to front the money.

Mechanism

How it works Giver

Paced Withholding

The employee tells their employer, via Form 145, about a recurring donation commitment. The employer adjusts monthly withholding, anticipating the corresponding deduction.

Applied example

A €240/year commitment translates into roughly €16 less withheld per month: the tax benefit arrives the same month as the donation, not a year later.

B2B integration

Designed to plug directly into flexible-benefits platforms already used by companies — a social benefit at no extra cost to the employer.

Product architecture

Giver 240 (individuals), Giver 145 (via payroll), Giver 48 (short recurrence), B Giver and GiverS (versions for B Corp companies).
