Ask Slashdot: Open Source Tax Software?

An anonymous reader writes "I finally started looking at my taxes and instead of handing over my personal information and money to TurboTax I was wondering if there were any recommendations for freely available/open source tax software? Ideally, the data would be stored in a portable, open format. I wouldn't really need a GUI, but something that filled out PDF forms would be nice." It's a question that just won't go away. Open source solution or not, if you're a U.S. taxpayer, the deadline for filing is nearly to hand.

    Here's one: https://sourceforge.net/projects/opentaxsolver/

    Having said that, I have found that paying a professional has always been a worthwhile investment. I have a masters degree in mathematics, so it's not a question of the calculations, but my accountant knows things about tax law that I don't, and keeps me from getting audited while getting me the best refunds that the law allows.

    no, the reason turbo tax costs money is they have teams of accountants translate new tax laws in every state into easy to fill out forms and the math functions behind them

    Also, TurboTax's online tool is free if you make under $31,000 (about $14.90/hr at full time). My girlfriend did it that way - it's called Freedom Edition or something.

    Liability always falls on the person filing the tax. Even with commercial software like TurboTax. This is why Intuit, H&R Block, etc offer liability protection and audit assistance as a selling point - to help reduce your actual liability.

    Fun Fact: Even if the IRS screws up, the taxpayer is still liable.

    It's sort of open source, as open as an excel spreadsheet goes anyway. Works fine in OpenOffice Calc. I've been using it for years, haven't been audited yet.

  6. Not Open Source, but at least it's free by Anonymous Coward · · Score: 3, Informative

    I'm a CPA and I would recommend using taxact.com. While it's not open source, it is free for any income level (for federal filing) and user friendly (if you can ignore the upselling of the deluxe version along the way). Given the frequency with which the tax law changes, it's doubtful a FOSS solution will emerge in this segment.

  7. IRS Site has Free Options by mikestew · · Score: 4, Informative

    If your main criteria is "freely available" and not "open source", and your adjusted gross income is less than $57K, you can just fill out the forms for free. It uses Adobe Flash if you have an aversion to such things, and there doesn't appear to be anything open source about it.

    If your AIG is more than $57K, your tax situation is probably such that you ought to be handing over some money to a pro or Turbo Tax.

    For complex returns, that may be correct. But there's no reason there can't be an open source product with consists of nothing more than an electronic version of the forms which allows you to type rather than print and which automatically does the math (on the forms) for you. Then it either prints or electronically submits the return. It's no different from picking up the paper forms and filling them out yourself. You're responsible for selecting the correct forms, knowing which laws apply, etc.

    As amazing as this seems, the IRS (and many state and muni tax agencies) have in fact figured out how to produce a form-style PDF that can be filled in ENTIRELY electronically. The IRS does make you do the math yourself, but I am sure you can find an open source calculator to help with that, right? Many state and munis seem to do this better, with forms that run all the math for you and can be submitted electronically. And believe it or not they even make them easy to find via Google. The wonder of it all!

    Seconding TaxAct. Cheapest and best. Does not phone home, as far as I know. It's the only reason I still have to have a virtualbox Windows taking up space on my drive.

    I've been looking for a reliable, complete FOSS alternative for years. I think, as others have said, it doesn't exist because nobody (me included if I knew how!) would do that kind of tedium for free.

    You realize there's more to many peoples' taxes than the single 1040-EZ you have to file... right?

    If you think that you can simply "follow the steps" like it's a mad libs, then you're either overpaying (in which case, thanks) or underpaying (in which case, pay up) on your taxes.

    But then, it's always been the case that those who know the least grossly overestimate their ability and competence.

    I don't think it's so much that as the principle of the thing.

    By demanding you file your tax online yet not providing a half-sane product to do this free of charge, the ability to file a tax return is itself subject to another charge that you can't easily avoid. Effectively, another tax.

    We have something similar in the UK - companies are legally obliged to file their tax returns online by submitting a file in a particular format. The format itself is open and based on XML, but pretty much the only things that support it are commercial applications aimed at the accounting industry. Which means you are forced to pay an accountant even if your affairs are simple enough you could easily fill in the forms yourself.

    IIRC they may also have a form online you can fill in. Haven't checked lately...
