## The answer, as recorded

Asked on 2026-10-08 through Claude (Anthropic) with web search (model claude-opus-5).

> Quick framing: nonprofits mostly file *information* returns (the 990 series), not income tax returns, so mainstream products like TurboTax Business won't do it. Here's what I'd actually point you to, roughly in the order I'd consider them.
> 
> **1. The IRS's own Form 990-N e-Postcard - free, and the right answer if gross receipts are normally ≤ $50,000.** Don't pay a vendor for this. It's eight data points (EIN, tax year, legal name/address, principal officer, a gross-receipts attestation) filed directly on IRS.gov. Three consecutive missed years = automatic revocation of exempt status, which is the real risk here, not the filing cost.

> 
> **2. Tax990 - best overall for a nonprofit self-filing a real return.** It's IRS-authorized and covers the whole series (990-N, 990-EZ, 990, 990-PF, 990-T, 8868 extensions), pulls your org's details from IRS records by EIN, copies prior-year data forward, auto-attaches the required schedules, and has internal error checks plus multi-user review/approval before transmit. Pay-per-return: $19.90 for a 990-N, $99.90 for a 990-
