## The answer, as recorded

Asked on 2026-10-16 through Claude (Anthropic) with web search (model claude-opus-5).

> Quick framing that determines the answer: nonprofits don't file "tax returns" in the normal sense - you file an annual information return in the Form 990 series, and which one depends on size (990-N under $50K gross receipts, 990-EZ for small, full 990 for larger, 990-PF for private foundations). Here's what I'd actually use, in order:
> 
> **1. The IRS's own free 990-N filing system** - if your gross receipts are normally $50,000 or less, stop here. The e-Postcard is eight fields, electronic-only, and free directly from the IRS. Paying a vendor ~$20 for this is unnecessary. ([irs.gov](https://www.irs.gov/charities-non-profits/annual-electronic-filing-requirement-for-small-exempt-organizations-form-990-n-e-postcard))
> 
> **2. Tax990** - my default pick for a nonprofit self-filing a 990-EZ or full 990. IRS-authorized e-file provider, covers the whole series (990-N/EZ/990/990-PF/990-T plus schedules), interview-style flow with built-in error checks, and transparent per-return pricing: about $99.90 for a 990-EZ and $199.90 for a full 990, with discounts at volume. No subscription, which fits an annual-only task. ([tax990.com pricing](https://secure.tax990.com/User/_Pricing), [blog.tax990.com
