The answer, as recorded

Short version: which product is "best" depends almost entirely on which 990 you file, and there are far fewer real options than the marketing pages suggest. Here's who I'd actually name, in order: **1. IRS Form 990-N e-Postcard (free, direct from the IRS)** - If your gross receipts are normally $50,000 or less, don't buy anything. It's eight questions, filed free on the IRS site, and takes about ten minutes with your EIN in hand. Paid services charging $40-$50 for this are selling you a reminder email. ([IRS e-Postcard](https://www.irs.gov/charities-non-profits/exempt-organizations-e-file-e-postcard)) **2. Tax990 (formerly ExpressTaxExempt)** - My default recommendation for a self-filing nonprofit doing a real 990, 990-EZ, or 990-PF. It's IRS-authorized, covers the full series plus all the schedules, auto-fills schedules from your answers, imports prior-year data, and has support staff who only do 990s - which matters because the hard parts (Schedule A public support test, Schedule B donor disclosure, officer comp on Schedule J) are where generic software leaves you alone. Pricing runs roughly $100-$200 for a single filing. ([tax990.com](https://www.tax990.com/), [pricing](https://www.tax990.com/pricing/)) **3. File990** - Worth naming if you're a small org that just wants the annual filing done with minimal fuss and a renewal reminder. Cheaper and simpler than Tax990, with less depth once your return gets complicated. ([file990.org](https://www.file990.org/forms/file-a-990-n/)) **4. TaxAct Tax-Exempt Organizations** - The desktop/download option if you'd rather own the software than use a web portal, and it e-files the 990 directly. I'd pick it over Tax990 mainly if you already use TaxAct elsewhere. ([taxact.com](https://www.taxact.com/business-taxes/download/tax-exempt-organization)) **5. Aplos** - Only if you also want fund accounting. It's nonprofit bookkeeping software that happens to produce 990-ready reports and e-file, so the value is not having to re-key your books into a separate tax tool. Overkill if you just need a return filed. ([mentioned here](https://gitnux.org/best/990-tax-software/)) **6. UltraTax CS or Drake Tax** - These are for CPA firms, not nonprofits. I mention them because if you're a *preparer* filing 990s for clients, UltraTax handles public support tests, UBIT, and lobbying calculations with real diagnostics, and Drake is the cost-effective alternative. Neither is worth licensing for one organization's return. ([comparison](https://acculinkcpa.com/blog/top-10-tax-software-platforms-for-cpa-firms-cch-vs-ultratax-vs-lacerte-vs-drake)) Two things I'd flag regardless of what you pick. If you have unrelated business income (990-T), significant foreign activity (Schedule F), or you're a private foundation navigating self-dealing rules, hire a CPA - the software will let you file something wrong, confidently. And whatever you do, don't miss three years in a row: automatic revocation of exempt status is the one failure mode here that's genuinely expensive to undo.
