Mozilla Foundation IRS audit now closed

November 3rd, 2012

In 2008 the US Internal Revenue Service opened an audit of the Mozilla Foundation. I’m happy to note that we’ve settled the issues raised and the IRS recently closed the audit. We entered into a settlement, under which the Mozilla Foundation paid the IRS US $1.5 million.

As a result of this settlement, $15 million in funds we had held in reserve pending the resolution of the audit are now available to support the Mozilla Foundation’s mission to support innovation and opportunity on the web.

I believe this to be a very positive result. We will now go back through the various documents and will have more details on this audit to share in the future. I expect to do so before the end of this year.

    Why was there an audit in the first place? Is that obligatory for a foundation in the US? And what are the costs based on? Just curious, maybe you can share some informational links about why this audit took place?

    the IRS chooses which organizations — taxable, tax-exempt, individuals, businesses — it wishes to understand better. We’ll share a bunch of info as soon as I have time to go through the doc again. Please look for this in the next couple of months.

    On a completely unrelated topic, could we add something to the page to ask people to donate to Hurricane Sandy Disaster relief with a link to the red cross donation site? just a question.

    4 years of IRS audit, ouch.

    It’s great news that it’s over, and it’s over with this result. Congratulations, and thanks for your patience! Looking forward to next developments from Mozilla Foundation.

    Hey! I realize this is kind of off-topic but I needed to ask.
    Does managing a well-established blog like yours require a lot of work?
    I am brand new to operating a blog however I do write in my
    journal on a daily basis. I’d like to start a blog so I can easily share my personal experience and thoughts online. Please let me know if you have any kind of ideas or tips for new aspiring blog owners. Thankyou!

    I believe Mozilla Foundation will be growth significant in a recent years.
    It is because the internet users believe about Firefox’s product that was stable and up to date
