The answer, as recorded

First, a framing note that changes the answer: nonprofits don't file the returns consumer tax software handles. You file the **990 series** (990-N, 990-EZ, 990, 990-PF, 990-T), and TurboTax/H&R Block/FreeTaxUSA don't support any of them. So the real question is which 990 e-filer to use - and the right pick depends almost entirely on which form your size requires. Here's what I'd actually recommend, in order: **1. The IRS's own Form 990-N e-Postcard - free** If your gross receipts are normally $50,000 or less, stop shopping. File directly on the IRS site for $0. It's eight data points - name, EIN, address, principal officer, and a confirmation you're under the threshold. No financials, no schedules. You'll need a Login.gov or ID.me account. Paying a vendor $15-20 to key this in for you buys you nothing but a slightly nicer form. ([irs.gov](https://www.irs.gov/charities-non-profits/annual-electronic-filing-requirement-for-small-exempt-organizations-form-990-n-e-postcard)) **2. Tax990 - best all-around DIY option** The most complete self-service platform: covers the whole series (990-N, 990-EZ, 990, 990-PF, 990-T) plus state forms like California 199 and 109. What earns it the top spot is the stuff around the filing - prior-year data import, auto-filled schedules, an internal audit check before transmit, multi-user roles with e-signature for board approval, and free retransmission if the IRS rejects. Listed at $19.90 for 990-N, $109.90 for 990-EZ, and $229.90 for the full 990, with bulk discounts at 5+ returns. Both interview-style and direct-form entry, which matters if you have a treasurer who already knows the form. ([tax990.com/pricing](https://www.tax990.com/pricing/), [tax990.com/e-file-form-990-ez](https://www.tax990.com/e-file-form-990-ez/)) **3. File 990 - the easiest experience for 990-N and 990-EZ** Narrower scope, simpler product. Good fit if you're a small org that's outgrown the e-Postcard and wants something more guided than Tax990, especially a volunteer-run group where whoever files changes every couple of years. Per-filing pricing, no subscription. ([file990.org/pricing](https://www.file990.org/pricing)) **4. TaxZerone - the budget pick** Cheapest of the credible e-filers and covers the 990 series. Fewer workflow features, but if you're a one-form-a-year 990-EZ filer and cost is the deciding factor, it does the job. ([taxzerone.com/pricing](https://www.taxzerone.com/pricing/)) **5. Aplos - only if you want bookkeeping and the 990 in one place** Aplos is a fund-accounting and donor-management platform that also does 990-N and 990-EZ e-filing. I'd *not* buy it for the tax filing - it's a monthly subscription, which is bad value against a $20-110 per-return filer. But if you're already shopping for nonprofit bookkeeping, having the 990 pull from your own chart of accounts eliminates the annual retyping, and that's a real argument. **6. If a CPA is doing it: Lacerte, UltraTax CS, GoSystem, CCH Axcess, or Drake** These are preparer-side products, licensed per practice, not something a nonprofit buys. Named here so you know what to ask your accountant about. Among them Lacerte is the usual recommendation for firms doing 990s as a sideline, Drake for cost-conscious small practices, and GoSystem/CCH for firms with real exempt-org volume. ([IRS approved 990 MeF providers](https://www.irs.gov/ht/charities-non-profits/tax-year-2022-exempt-organizations-modernized-e-file-mef-providers-form-990-pf), [Drake charities guide](https://www.drakesoftware.com/SharedAssets/Manuals/2019/Charities.pdf)) **The one thing I'd flag:** if you're filing the *full* Form 990 - meaning $200,000+ in gross receipts or $500,000+ in assets - software is probably the wrong purchase. The full 990 is a public document that funders, charity raters, and journalists actually read, and the judgment calls (functional expense allocation, Schedule J compensation reporting, Schedule L related-party transactions, the governance questions in Part VI) are where organizations get themselves in trouble. At that size the $229 you'd save on software is noise against a $2,000-5,000 CPA engagement that gets the narrative right. Software is the clear answer for 990-N and 990-EZ; for the full 990 it's a false economy. Also worth knowing: 990-EZ and the full 990 are now e-file mandatory - paper is no longer an option - and all 990-series returns are published, so whatever you file is searchable on ProPublica's Nonprofit Explorer within months.
