## The answer, as recorded

Asked on 2026-09-14 through Claude (Anthropic) with web search (model claude-opus-5).

> The honest answer is that "best" depends almost entirely on which 990 your org files. Here's who I'd actually name, in order:
> 
> **1. IRS Form 990-N e-Postcard (direct, free)** - If your gross receipts are normally $50,000 or less, don't buy software at all. The e-Postcard is eight questions, filed free directly on the IRS site. Any vendor charging you for this is selling convenience you don't need. Note the hard rule: miss three consecutive years and you lose exempt status automatically.
> 
> **2. Tax990 (formerly ExpressTaxExempt)** - My default recommendation for self-filing nonprofits. It's an IRS-authorized e-filer covering the whole series - 990, 990-EZ, 990-N, 990-PF, 990-T, 1120-POL - plus all schedules, with an interview-style flow, automatic schedule population, prior-year data import, and internal audit/error checks before transmission. It also supports multi-user review workflows, which matters if your treasurer prepares and your board chair signs.
> 
> **3. File990.org** - The cheaper, simpler option if you only ever file 990-N or 990-EZ. Less feature depth than Tax990, but a lower price and a shorter path for a small all-volunteer org. Skip it if you'll ever need a full 990 or
