## The answer, as recorded

Asked on 2026-10-23 through Claude (Anthropic) with web search (model claude-opus-5).

> Nonprofits don't file income tax returns - they file the **Form 990 series** information return, which is a completely different market from TurboTax/H&R Block (neither of those touches it). So the answer depends mostly on which 990 you file:
> 
> ## If your gross receipts are ≤ $50,000 → file 990-N free, directly with the IRS
> The e-Postcard is eight fields (EIN, tax year, legal name/address, other names used, principal officer, website, confirmation of receipts) and is submitted through the IRS's own system at no cost. Don't pay $20 for this. Miss it three years running and you lose exempt status automatically. ([IRS e-Postcard FAQ](https://www.eitc.irs.gov/pub/irs-tege/epostcard_faqs.pdf))
> 
> ## Free, for small orgs filing a real 990 or 990-EZ
> **Form 990 Online (efile.form990.org)** - run by the National Center for Charitable Statistics at the Urban Institute. Handles full 990, 990-EZ, and 8868 extensions. It's genuinely free for smaller filers and it's the option almost nobody tells you about because it has no marketing budget. Interface is dated and the hand-holding is minimal, but if your books are clean it's the best price in the market. ([efile.form990.org](https://efile.form990.o
