If an entire industry can be killed by a public service, it probably didn't deserve to exist in the first place.
I disagree. If anything, this will compel the tax preparation software companies to get even better than before, and offer an increased value proposition. Competition benefits the consumer, and for a long while there's been limited, mostly fixed competition (via Brand awareness mostly). FreeTaxUSA is amazing, and cheap, but it does not yet have the brand power the incumbents do. It's unlikely the IRS offering will be…
Yes, there are alternatives, but what possible enhancement could any of them provide that is worth anything? Tax preparation is largely deterministic, and maximizing deductions is a largely human-lead task that is only beneficial to higher earners who have an accountant that does their taxes for them and don't care about services like TurboTax and FreeTaxUSA.
For most working class Americans a guaranteed free solution provided by the IRS itself is a no-brainer. You know that the government isn't in the business of maximizing profits at all costs, and you get the peace of mind that the IRS itself calculated your taxes, and that you are unlikely to get the blame if there is an error.
Tax collection is a critical function that the government relies on, it should overwhelmingly be a government-lead process that doesn't cost people any more than what they owe in taxes. I hope all of these predatory tax filing businesses go under, because paying taxes is a civic duty that people shouldn't be reliant on private organizations to fulfill for them.
