The question asked, verbatim: best tax preparation software for nonprofits

Brands named, in the order the engine gave

1. Form 990 mentioned
   Short version: nonprofits don't file a normal income-tax return, so what you actually need is Form 990-series software (990-N, 990-EZ, 990, 990-PF, plus 990-T if you have unrelated business income).
2. US mentioned
   It's an IRS-authorized e-file provider covering the whole series (990, 990-EZ, 990-N, 990-PF, 990-T, 1120-POL) and all schedules, with interview-style prep, auto-populated schedules, prior-year import, internal audit/error checks, and US-based support that only does 990s.
3. TaxBandits mentioned
   TaxBandits - Same parent company and essentially the same filing engine, but worth naming separately because if you're already using it for 1099s and W-2s, you can keep payroll-adjacent reporting and the 990 in one account.
4. File 990 mentioned
   File 990 - The cheapest credible option for small and mid-size orgs, and genuinely fast for 990-N and 990-EZ.
5. Aplos mentioned
   Aplos - Pick this if your bookkeeping is the actual problem.
6. TaxAct mentioned
   TaxAct Tax-Exempt Organizations - A solid, familiar desktop download for 990/990-EZ/990-N with e-file.
7. TaxAct Tax-Exempt Organizations mentioned
   TaxAct Tax-Exempt Organizations - A solid, familiar desktop download for 990/990-EZ/990-N with e-file.
8. Thomson Reuters UltraTax CS mentioned
   Thomson Reuters UltraTax CS or CCH Axcess Tax - Only relevant if you're a CPA firm or a large nonprofit with in-house tax staff.
9. UltraTax CS mentioned
   Thomson Reuters UltraTax CS or CCH Axcess Tax - Only relevant if you're a CPA firm or a large nonprofit with in-house tax staff.
10. Full Form 990 mentioned
    Two things worth knowing regardless of which you pick: a full Form 990 with complicated schedules (compensation, foreign activity, related orgs, fundraising events) is often cheaper and safer to hand to a nonprofit-specialist CPA than to DIY - the return is a public document that funders read.

The answer, as recorded

Short version: nonprofits don't file a normal income-tax return, so what you actually need is Form 990-series software (990-N, 990-EZ, 990, 990-PF, plus 990-T if you have unrelated business income). Here's what I'd actually point you to, in order: **1. IRS Form 990-N Electronic Filing System (free)** - If your gross receipts are normally $50,000 or less, stop here. The "e-Postcard" is eight questions, filed directly on IRS.gov, and costs nothing. Paying a vendor for this is throwing money away. Miss it three years running and you lose exempt status automatically, so just set a calendar reminder for the 15th day of the 5th month after your year end. ([IRS e-Postcard](https://www.irs.gov/charities-non-profits/exempt-organizations-e-file-e-postcard), [who must file](https://www.irs.gov/charities-non-profits/annual-electronic-notice-form-990-n-for-small-organizations-faqs-who-must-file)) **2. Tax 990** (formerly ExpressTaxExempt) - My default recommendation for any org self-filing a real return. It's an IRS-authorized e-file provider covering the whole series (990, 990-EZ, 990-N, 990-PF, 990-T, 1120-POL) and all schedules, with interview-style prep, auto-populated schedules, prior-year import, internal audit/error checks, and US-based support that only does 990s. Pricing scales with form complexity rather than a big annual license. ([tax990.com](https://www.tax990.com/)) **3. TaxBandits** - Same parent company and essentially the same filing engine, but worth naming separately because if you're already using it for 1099s and W-2s, you can keep payroll-adjacent reporting and the 990 in one account. ([taxbandits.com](https://www.taxbandits.com/form-990-series/)) **4. File 990** - The cheapest credible option for small and mid-size orgs, and genuinely fast for 990-N and 990-EZ. Thinner on complex schedules and the bigger 990, so I'd treat it as the budget pick rather than the all-rounder. ([file990.org](https://www.file990.org/forms/file-a-990-n/)) **5. Aplos** - Pick this if your bookkeeping is the actual problem. It's fund-accounting software for nonprofits and churches with 990 filing bolted on, so the return pulls from your chart of accounts instead of being retyped. Overkill if you only want to file a form; the right answer if your books are a spreadsheet mess. ([aplos.com](https://www.aplos.com/irs-form-990-efile)) **6. TaxAct Tax-Exempt Organizations** - A solid, familiar desktop download for 990/990-EZ/990-N with e-file. Reasonable if someone on staff already knows the TaxAct interface; otherwise the cloud options above are less clunky. ([taxact.com](https://www.taxact.com/business-taxes/download/tax-exempt-organization)) **7. Thomson Reuters UltraTax CS or CCH Axcess Tax** - Only relevant if you're a CPA firm or a large nonprofit with in-house tax staff. Both have real 990 modules with consolidated workflows and multi-state support, at firm-level pricing. Note that Drake Tax handles 990 but won't convert prior-year 990 data, so switching to it means manual entry. ([UltraTax modules](https://www.oneupnetworks.com/post/ultratax-cs-tax-software-cloud-hosting/), [Drake conversion FAQ](https://kb.drakesoftware.com/kb/Drake-Tax/10869.htm)) Two things worth knowing regardless of which you pick: a full Form 990 with complicated schedules (compensation, foreign activity, related orgs, fundraising events) is often cheaper and safer to hand to a nonprofit-specialist CPA than to DIY - the return is a public document that funders read. And none of these handle state charitable-solicitation registrations or state annual reports, which are a separate obligation in most states.
