## The answer, as recorded

Asked on 2026-10-03 through Claude (Anthropic) with web search (model claude-opus-5).

> Short version: "nonprofit tax software" really means Form 990-series e-filing, and the right pick depends almost entirely on which 990 you file.
> 
> **1. The IRS's own 990-N e-Postcard system - free.** If your gross receipts are normally $50,000 or less, you file the e-Postcard directly on IRS.gov for $0. It's eight fields. Paid services charge $20-$55 for this and add nothing. Start here before considering anything else. ([IRS](https://www.irs.gov/charities-non-profits/annual-electronic-notice-form-990-n-for-small-organizations-faqs-who-must-file))
> 
> **2. Tax990 - best overall for self-filing organizations.** The most complete dedicated 990 platform: full 990, 990-EZ, 990-N, 990-PF, 990-T, plus all the schedules, extensions, and amended returns. Guided interview, internal audit/error checks, and multi-user review workflow so your treasurer can prep and the board chair can approve. ~$19.90 for 990-N, ~$109.90 for 990-EZ, ~$229.90 for the full 990, charged only on transmission. If I had to name one product, this is it. ([tax990.com](https://www.tax990.com/pricing/))
> 
> **3. TaxZerone - the budget alternative.** Same IRS-authorized e-filing, meaningfully cheaper on the 990-EZ/990 tiers. Fe
