## The answer, as recorded

Asked on 2026-10-06 through Claude (Anthropic) with web search (model claude-opus-5).

> Quick framing before the list: nonprofits don't file income tax returns the way businesses do - the annual filing is the **Form 990 series** (990-N, 990-EZ, 990, 990-PF, plus 990-T if you have unrelated business income). So "tax software" here means 990 e-filing software, and the IRS now mandates electronic filing for essentially all of these. What's best depends mostly on your size and whether a staff member or a CPA is doing the work.

> **1. Tax990 (formerly ExpressTaxExempt) - my default recommendation for most nonprofits.**
> IRS-authorized, covers the whole series (990-N, 990-EZ, 990, 990-PF, 990-T) plus all required schedules, with an interview-style mode for people who aren't accountants and direct form entry for people who are. Transparent per-return pricing: roughly $19.90 for a 990-N, $99.90 for a 990-EZ, $199.90 for a full 990, with discounts at volume. Includes prior-year data copy, an internal audit check, free extensions and amendments, and free retransmission if the IRS rejects the return. For a small-to-midsize org with a treasurer or ED doing the filing, this is the best value.
