## The answer, as recorded

Asked on 2026-09-12 through Claude (Anthropic) with web search (model claude-opus-5).

> Short version: "tax software for nonprofits" almost always means Form 990-series e-filing, and the right pick depends on which flavor of 990 you file. Here's what I'd actually recommend, in order:
> 
> **1. The IRS's own Form 990-N e-Postcard system - if your gross receipts are normally ≤$50,000.** It's free, it's eight fields, and it takes about five minutes. Don't pay a vendor $50-$130 for this. The only real caution: three consecutive missed years means automatic revocation of exempt status, so calendar it (due the 15th day of the 5th month after year-end).

> 
> **2. Tax990 (formerly ExpressTaxExempt) - the best all-around DIY choice for 990-EZ and full 990 filers.** It covers the whole series (990-N, 990-EZ, 990, 990-PF, 990-T, 8868 extensions, 1120-POL), auto-generates the schedules based on your answers, has internal audit/error checks before transmission, and supports a board-review-and-approve workflow before you e-file - genuinely useful when a treasurer preps and a board chair signs. This is my default recommendation for a small-to-midsize org filing
