## The answer, as recorded

Asked on 2026-09-27 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd rank them, depending on which 990 you actually file:
> 
> **1. Tax 990 (formerly ExpressTaxExempt) - best overall for most nonprofits self-filing**
> IRS-authorized, covers the whole series (990-N, 990-EZ, 990, 990-PF, 990-T, 1120-POL) plus auto-included schedules, extensions (8868), and amended returns. Pricing is transparent: ~$19.90 for 990-N, ~$109.90 for 990-EZ, ~$229.90 for a full 990. It also has internal review/approval workflow for boards, which matters if your treasurer prepares and the ED signs off. Volume pricing (~$14.90-$17.90/return) if you're a bookkeeper filing for multiple orgs.

> 
> **2. The IRS's own 990-N e-Postcard portal - if your gross receipts are ≤$50,000, use this and pay nothing**
> It's eight data fields. Don't buy software for it. The only reason to pay a vendor for a 990-N is if you want filing records and reminders kept alongside other orgs.

> **3. File 990 - best for small orgs that only ever file 990-N or 990-EZ**
