The answer, as recorded

The honest answer is that "best" depends almost entirely on which 990 your org files. Here's who I'd actually name, in order: **1. IRS Form 990-N e-Postcard (direct, free)** - If your gross receipts are normally $50,000 or less, don't buy software at all. The e-Postcard is eight questions, filed free directly on the IRS site. Any vendor charging you for this is selling convenience you don't need. Note the hard rule: miss three consecutive years and you lose exempt status automatically. **2. Tax990 (formerly ExpressTaxExempt)** - My default recommendation for self-filing nonprofits. It's an IRS-authorized e-filer covering the whole series - 990, 990-EZ, 990-N, 990-PF, 990-T, 1120-POL - plus all schedules, with an interview-style flow, automatic schedule population, prior-year data import, and internal audit/error checks before transmission. It also supports multi-user review workflows, which matters if your treasurer prepares and your board chair signs. **3. File990.org** - The cheaper, simpler option if you only ever file 990-N or 990-EZ. Less feature depth than Tax990, but a lower price and a shorter path for a small all-volunteer org. Skip it if you'll ever need a full 990 or 990-PF. **4. Aplos** - Worth it specifically if you already use Aplos for fund accounting. The value is that your books and your 990 live in one system, so the return pulls from your actual ledger instead of a spreadsheet you retype. As standalone 990 software it's not compelling, and pricing requires contacting them. **5. TaxAct Tax-Exempt Organization Edition** - A reasonable desktop middle ground if you want a traditional forms-based product rather than a web interview, and e-files 990 directly with the IRS. **6. Drake Tax / Intuit ProConnect / UltraTax CS / CCH Axcess** - These are for your CPA, not for you. If you file a full 990 with significant schedules, a 990-PF, or have UBIT on a 990-T, hire a nonprofit-experienced CPA and let them use their own platform. Drake's flat unlimited-return pricing makes it common at small firms; CCH Axcess and UltraTax show up at larger ones. One practical note regardless of vendor: verify the provider is on the IRS authorized e-file list before paying, and confirm it supports every schedule you need - Schedule B donor reporting and Schedule A public support tests are where cheap tools tend to fall short.
