TurboTax has free self-service for qualifying people, and TurboTax Live Assisted, where you file online with tax expert help if needed, and TurboTax Full Service, where a tax expert will do your taxes and review them with you before filing. Here’s the nitty gritty: friends can receive 20% off the preparation and filing of federal tax return or business federal tax return through a TurboTax Online or TurboTax Live product, through October 31. TurboTax ensures a “Maximum Refund Guarantee,” meaning if you get a larger refund or less taxes due from another tax preparation method, they’ll refund the applicable TurboTax federal and/or state purchase price paid.
