Your $40,000 Donation Just Raised Your Medicare Bill

You write a check to your church every December. Same amount. Same church. Same feeling. Starting in 2026, that check passes through three machines before it helps you on your taxes. Each one takes a bite.

The One Big Beautiful Bill Act created a new floor under your charitable deduction. The first 0.5% of your income in giving? Dead. Gone. No deduction. Think of it as the first water out of the pipe hitting the ground before it reaches the bucket.

Say your AGI is $250,000. Half a percent of that is $1,250. Your first $1,250 in donations does nothing on your return. At $500,000 AGI, the dead zone is $2,500. That money fell through the hole. You gave it. God bless. But the IRS shrugs.

And here's the part that stings. For most donors, those lost dollars don't carry forward. They're gone.

What survived the floor gets shaved again. The new law caps the tax benefit of your itemized deductions at 35 cents on the dollar instead of 37. They call it the 2/37ths rule. I call it the skim.

Sure. Two grand. Doesn't sound like much. But stack it on the floor you already lost. And remember: the ordering matters. The floor hits first. Then the cap shaves what's left. Both losses are permanent. No carryforward on the cap either.

Two cuts. Both invisible unless you read the fine print. Both forever.

This is the one I find interesting.

You're retired. You pull $40,000 from your IRA to fund the church donation. That $40,000 lands in your bank account. It counts as income. You write the check. You claim the deduction. But the deduction just got chewed by the floor and the cap. Meanwhile, the full $40,000 pumped up your MAGI.

And MAGI is what Medicare uses to set your premium surcharge. They call it IRMAA.

IRMAA works like a cliff. Not a slope. A cliff. For a married couple filing jointly, the 2026 threshold is $218,000. One dollar over that line and your Medicare premium jumps. Both of you. The surcharge is $1,148 per person per year. A married couple pays $2,296 extra. Because of a donation.

I mean. You gave money to your church. And Medicare charged you for it.

(The surcharges can climb to $6,936 per person per year at higher tiers. But that first cliff is the one most retirees will trip over.)

Look. There is one pipe that bypasses all three machines. It's called a Qualified Charitable Distribution. QCD.

Here's how it works. The money goes straight from your IRA to the church. It never touches your bank account. It never hits your AGI. It never shows up in your MAGI.

Floor? Doesn't apply. The money was never a deduction. It was never income in the first place.

Cap? Doesn't apply. Same reason.

IRMAA cliff? You stayed under it. The $40,000 never inflated your income. Medicare never saw it.

And if you're 73 or older, the QCD counts toward your Required Minimum Distribution. Dollar for dollar. The IRS forced you to pull money out. You sent it to church instead. Done.

You must be 70½ or older. The money must come from an IRA. Not a 401(k). Not a 403(b). The limit is $111,000 per person in 2026. Married couple with two IRAs? $222,000.

The check must go straight from the IRA custodian to the charity. Trustee to trustee. If the money hits your personal account first, even for a day, you lose everything. It becomes taxable income. The whole point collapses.

One more thing. QCDs cannot go to a donor-advised fund. Cannot go to a private foundation. Must be a real 501(c)(3). Your church counts. Your community fund counts. Your DAF does not.

The church still gets the same money. The amount is the same. The only thing that changed is which pipe it travels through.

Same donation. Three fewer cuts.
