## The answer, as recorded

Asked on 2026-10-19 through Claude (Anthropic) with web search (model claude-opus-5).

> Quick framing: nonprofits don't file a "tax return" like a business does - you file an annual **information return** in the 990 series (990-N, 990-EZ, 990, or 990-PF), and e-filing has been mandatory since the Taxpayer First Act.

> 
> **2. [Tax990](https://www.tax990.com/pricing/)** - My default recommendation for a self-filing nonprofit on 990-EZ or full 990. IRS-authorized, covers the whole series (990-N, 990-EZ, 990, 990-PF, 990-T) plus Form 8868 extensions, California Forms 199/109, and 1120-POL. It auto-attaches the required schedules, imports prior-year data, has an internal audit check before transmission, and includes free retransmission if the IRS rejects. Pricing is $19.90 for 990-N, $109.90 for 990-EZ, $229.90 for 990, with volume dis
