## The answer, as recorded

> # Best tax prep software for nonprofits
> 
> The right answer depends almost entirely on which 990 you file, so here's my ranked list with that in mind.
> 
> **1. IRS Form 990-N e-Postcard (free, directly from the IRS)** - If your gross receipts are $50,000 or less, stop here. File at [irs.gov/990n](https://www.irs.gov/charities-non-profits/annual-electronic-notice-form-990-n-for-small-organizations-faqs-how-to-file). It's eight data fields and it costs nothing. Paid services charging ~$55 for this are selling you a nicer interface around a form you can finish in ten minutes. Note the old Urban Institute site (efile.form990.org) hasn't handled 990-N since 2016 - it now redirects to the IRS.
> 
> **2. [Tax990](https://www.tax990.com/) (formerly ExpressTaxExempt)** - My default recommendation for nonprofits filing a real return (990-EZ, full 990, 990-PF, or 990-T) without a CPA. It covers the whole series plus schedules, pulls your org details automatically from IRS records via EIN, runs an internal error check before transmission, and supports board-member review workflows before filing. Prior-year and amended returns are supported too.
> 
> **3. [TaxBandits](https://www.taxbandits.com/form-990-ser
