Charitable Giving Tax Calculator

The rules for charitable giving changed for tax year 2026. Three of the decisions people ask about most, run on your own numbers: whether to bunch several years of giving into one, whether to give from an IRA instead of writing a check, and whether to give appreciated stock instead of cash.

Bunch or give every year

New for 2026: itemized charitable gifts only count above one half of one percent of your income. Giving the same amount every year pays that toll every year. Concentrating several years of giving into one pays it once.

Give from your IRA, or write a check

From age 70 and a half you can send money straight from a traditional IRA to a charity. It never lands in your income at all, which is different from taking the money out and deducting the gift. The 2026 limit is $111,000 per person.

Give stock, or sell it and give cash

If you have held a stock more than a year and it has gone up, giving the shares directly can beat selling them first. You skip the capital gains tax and can still deduct the full market value, though a lower ceiling applies to gifts of property.

What this calculator does not do

Every calculator makes assumptions. Most do not tell you what they are. Here are ours, so you can judge whether the answer applies to you.

It does not model

  • State and local income tax. Federal only. Several states do not follow the new federal charitable rules, so your state answer can differ from this one.
  • The alternative minimum tax, the qualified business income deduction, or the taxation of Social Security benefits.
  • Medicare premium surcharges. Income above certain thresholds raises your Part B and Part D premiums two years later. This can make keeping income down worth more than the tax number alone suggests, which matters most in the IRA comparison.
  • Deduction carryforwards from earlier years, or gifts to private foundations, donor advised funds, and supporting organizations, which follow different limits.
  • Anything about whether you should give at all. That is not a tax question.

Which way it is likely to be wrong

Where it errs, it errs toward understating the benefit of giving from an IRA, because keeping income lower also helps with Medicare premiums, the taxable share of Social Security, and other thresholds tied to income that are not modeled here. For the bunching and stock comparisons the figures should be close, though a large gift can push you between brackets in ways a simpler estimate would miss. This tool computes your actual tax twice and takes the difference, rather than multiplying a deduction by a tax rate, which is why its answers may be smaller than the numbers other calculators show.

Where the numbers come from

The 2026 brackets, standard deduction, and capital gains thresholds come from IRS Revenue Procedure 2025-32. The half percent floor, the deduction for people who do not itemize, the cap on the value of itemized deductions, and the permanent 60 percent ceiling on cash gifts come from Public Law 119-21. The 2026 IRA charitable distribution limit of $111,000 comes from IRS Notice 2025-67.
