Edit: I contacted Every.org and they clarified that their email was incorrect. Details are below.

I got an email from Every.org saying that non-itemizers can now deduct up to $1000 of charitable donations on this year's taxes:

But I'm seeing conflicting information on whether this applies starting with this year's income, or next year's. Here's a relevant article from the Tax Foundation:

The expansion takes effect for tax year 2025, and the standard deduction will be $15,750 for single filers and $31,500 for joint filers in 2025 (and inflation-adjusted thereafter). Tax Foundation estimates nearly 86 percent of taxpayers will take the standard deduction in 2026, an increase from projections under TCJA policy.
Taxpayers who take the standard deduction have not typically been able to deduct their charitable donations on their tax returns. The OBBBA, however, creates a permanent above-the-line deduction for charitable donations of $1,000 per filer who takes the standard deduction beginning in tax year 2026.

which looks like it's saying the standard deduction is increased for income earned in 2025, and the above-the-line deduction goes into effect for income earned in 2026. Which interpretation is right?

Update: the above-the-line tax deduction for filers who do not itemize goes into effect for income earned in 2026. The standard deduction is increased in 2025, but you cannot deduct charitable donations on your 2025 tax returns unless you itemize, as before. Starting next year, everyone will be able to deduct up to $1000 of charitable donations.
