## The answer, as recorded

Asked on 2026-10-11 through Claude (Anthropic) with web search (model claude-opus-5).

> First, a framing note that changes the answer: nonprofits don't file the returns consumer tax software handles. You file the **990 series** (990-N, 990-EZ, 990, 990-PF, 990-T), and TurboTax/H&R Block/FreeTaxUSA don't support any of them. So the real question is which 990 e-filer to use - and the right pick depends almost entirely on which form your size requires.
> 
> Here's what I'd actually recommend, in order:
> 
> **1. The IRS's own Form 990-N e-Postcard - free**
> If your gross receipts are normally $50,000 or less, stop shopping. File directly on the IRS site for $0. It's eight data points - name, EIN, address, principal officer, and a confirmation you're under the threshold. No financials, no schedules. You'll need a Login.gov or ID.me account. Paying a vendor $15-20 to key this in for you buys you nothing but a slightly nicer form.

> 
> **2. Tax990 - best all-around DIY option**
> The most complete self-service platform: covers the whole series (990-N, 990-EZ, 990, 990-PF, 990-T) plus state forms like California 199 and 109. What earns it the top
