The answer, as recorded

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. ([irs.gov](https://www.irs.gov/charities-non-profits/annual-electronic-notice-form-990-n-for-small-organizations-faqs-how-to-file)) **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-EZ, $169.90 for a 990-PF, $199.90 for a full 990, with volume discounts at 5+ returns. That's the strongest price-to-capability ratio I know of in this space. ([tax990.com/pricing](https://www.tax990.com/pricing/), [support.tax990.com](https://support.tax990.com/art/17691/what-is-the-cost-to-file-990-series-forms-through-tax990)) **3. File 990 - for a volunteer treasurer who wants the absolute simplest path.** Narrower (geared to 990-N and 990-EZ) and generally pricier per return than Tax990, but the interview-style flow is genuinely friendlier if nobody on your board has done this before. Worth it if the alternative is not filing. ([file990.org](https://www.file990.org/blog/best-nonprofit-tax-software-available-even-novice-treasurer)) **4. Aplos - if your bookkeeping is also a mess.** Fund-accounting software built for nonprofits with 990 prep attached, so the return populates from your actual books rather than from a spreadsheet you rebuild each May. Buy this for the accounting and treat the 990 as a bonus; don't buy it *only* for the 990. ([aplos.com](https://www.aplos.com/academy/nonprofit/nonprofit-accounting/free-irs-990-filing-aplos/)) **5. TaxAct Tax-Exempt Organizations - the familiar-brand DIY option.** Handles the full 990 and, unusually, supports CA and TX state exempt filings. Reasonable if you already use TaxAct elsewhere; otherwise Tax990 is better value. ([taxact.com](https://www.taxact.com/support/20837/2024/form-990-non-profit-organization-501-c-3)) **If you're a CPA firm or a large/multi-entity organization**, different tier entirely: - **CCH Axcess Exempt Organizations** (Wolters Kluwer) - 990/990-EZ/990-PF integrated with the rest of a firm's tax workflow. ([wolterskluwer.com](https://www.wolterskluwer.com/en/solutions/cch-axcess/tax/990-exempt-organizations)) - **Thomson Reuters UltraTax CS** - full e-file and calc support for 990, 990-EZ, 990-N, 990-PF, 990-T, 4720, 5227; the deepest form coverage of the group. ([thomsonreuters.com](https://www.thomsonreuters.com/en-us/help/ultratax-cs/990/processing/prepare-form-990-ez-instead-of-990)) - **Intuit Lacerte / ProConnect Tax** - 990 series alongside 706/709/5500. ([accountants.intuit.com](https://accountants.intuit.com/support/en-us/help-article/form-990/common-questions-form-990-990-pf-990-990-n/L54bCsJqE_US_en_US)) - **K1x / 990 Tracker** - for foundations and big exempts drowning in K-1s and multi-entity data collection. Two things the software won't solve, so I'd flag them: if you have **unrelated business income** you also owe a **990-T**, which is an actual tax return and where I'd involve a CPA rather than DIY. And none of these handle **state charitable-solicitation registrations** (CA RRF-1, etc.) - that's a separate chore, usually Harbor Compliance or Labyrinth. Honestly, if you're filing a full 990 with audited financials and compensation schedules, the right answer is a nonprofit-specialist CPA using one of the professional tools above; the DIY products shine at 990-N and 990-EZ.

I ignored those; the ordering above reflects form coverage, pricing I could verify on vendor pricing pages, and who the tool is actually built for.
