The answer, as recorded
## The short version "Tax prep software for nonprofits" almost always means **Form 990-series e-filing**, not income tax prep - a 501(c)(3) doesn't owe income tax, it files an annual information return. Which product is right depends almost entirely on which 990 you file, so here's the order I'd actually give: **1. The IRS's own Form 990-N e-Postcard system - free.** If your gross receipts are normally $50,000 or less, you file the e-Postcard and nothing else. It's eight data fields on the IRS site. Do not pay anyone for this. ([IRS](https://www.irs.gov/charities-non-profits/annual-electronic-filing-requirement-for-small-exempt-organizations-form-990-n-e-postcard)) **2. Tax990 (formerly ExpressTaxExempt) - best all-around paid option for a nonprofit filing its own return.** It's IRS-authorized across the whole series (990-N, 990-EZ, 990, 990-PF, 990-T) plus state forms like CA 199, so you don't have to switch vendors when you outgrow the EZ. It auto-attaches required schedules, imports prior-year data, has an internal audit check before transmission, and includes free extensions, amendments, and retransmission of rejected returns. Published per-return pricing is roughly $109.90 for a 990-EZ and about $200-$230 for a full 990 - verify on their pricing page, since the figures quoted in different places don't agree. ([tax990.com pricing](https://www.tax990.com/pricing/), [Capterra](https://www.capterra.com/p/10041549/Tax990/)) **3. File990.org - the cheapest sane entry point for 990-N and 990-EZ only.** Narrower than Tax990, but if you're a volunteer treasurer who just needs the EZ done section by section once a year, the simpler interface is a real advantage. ([File990](https://www.file990.org/blog/best-nonprofit-tax-software-available-even-novice-treasurer)) **4. Aplos - pick this if you want bookkeeping and the 990 in one place.** Aplos is fund-accounting software for nonprofits that also does 990 prep and e-file (IRS-authorized since 2012, and free for 990-N). Buying it purely as tax software is overkill; buying it because your chart of accounts is a mess and the 990 falls out of clean books is a good reason. ([Wikipedia](https://www.wikipedia.com/wiki/Aplos_Software)) **5. Drake, TaxAct Professional, or Intuit ProConnect/Lacerte - only if you're the accountant, not the nonprofit.** These are professional preparer suites priced and designed for firms filing many returns with multi-preparer review workflows. A single organization filing one return a year should not buy one. ## The thing worth saying out loud If you file a **full Form 990 or a 990-PF**, or you have unrelated business income (990-T), employees in multiple states, or anything approaching an audit requirement - hire a CPA who does exempt-org work rather than buying software. The full 990 is a public document that funders, Candid/GuideStar, and charity raters read; Schedule A public support tests and Schedule J compensation reporting are where organizations get themselves in trouble, and software will happily let you file a technically-accepted return that misrepresents you. Expect roughly $300-$1,200 per return for professional prep depending on complexity. One caution on sources: several of the top-ranking "Top 10 Best 990 Software of 2026" pages (gitnux, zipdo, worldmetrics) are auto-generated affiliate content with no actual testing behind the rankings. I've leaned on vendor and IRS primary sources above instead. **Sources:** - [IRS - Form 990-N (e-Postcard) filing requirement](https://www.irs.gov/charities-non-profits/annual-electronic-filing-requirement-for-small-exempt-organizations-form-990-n-e-postcard) - [Tax990 - Pricing](https://www.tax990.com/pricing/) - [Tax990 - Form 990 electronic filing](https://www.tax990.com/form-990-electronic-filing) - [Capterra - Tax990](https://www.capterra.com/p/10041549/Tax990/) - [File990 - nonprofit tax software](https://www.file990.org/blog/best-nonprofit-tax-software-available-even-novice-treasurer) - [Aplos Software](https://www.wikipedia.com/wiki/Aplos_Software)
