Yes: the non-itemizer deduction of $1,000 ($2,000 married filing jointly)2026 · IRS, the 0.5% of AGI2026 · IRS floor and the benefit capped at 35%2026 · IRS for top-bracket itemizers.
Is the EIC calculator a substitute for the IRS EIC table?

Who uses the clergy housing allowance calculator?
Ministers and the preparers who serve them. It compares the designated allowance with actual costs and fair rental value.

Why put a credit calculator on a firm site?
Credit questions often come from households who need a return prepared. An EIC estimate followed by a request is a clear engagement.
Do they handle phase-outs?
The EIC calculator models phase-in and phase-out by income. Others note phase-outs they leave out.
Can we feature these in the fourth quarter?
