## The answer, as recorded

Asked on 2026-10-18 through Claude (Anthropic) with web search (model claude-opus-5).

> Quick framing, because it changes the answer: nonprofits generally don't file an income tax return - they file an annual **information return** (990-N, 990-EZ, 990, or 990-PF for private foundations), plus Form 990-T only if you have unrelated business income. Consumer tax software like TurboTax/H&R Block doesn't do these at all. Here's what I'd actually use, in order:
> 
> **1. The IRS's own 990-N e-Postcard filing system - free**
> If your gross receipts are normally ≤$50,000, stop here. It's eight data points (legal name, address, EIN, principal officer, confirmation of receipts), takes ten minutes, and costs nothing. Don't pay a vendor for this. ([irs.gov/990n](https://www.irs.gov/charities-non-profits/annual-electronic-filing-requirement-for-small-exempt-organizations-form-990-n-e-postcard))
> 
> **2. Tax990 - best for most small/mid nonprofits self-filing**
> The strongest purpose-built option. IRS-authorized, covers 990-N, 990-EZ, 990, 990-PF, and 990-T, includes the Schedule A-R set automatically, has an interview-style mode plus direct form entry, prior-year data import, internal audit checks, and free extensions, amendments, and retransmission of rejected returns.
