Even before it became that easy, it was always possible to get a so-called “R75” statement before filing. R75 contains all the information that the tax authority has on you for a given tax year, including all filings from employers, banks, stock brokers, lenders, etc. That way it was easy to see if you missed anything and to double check the return.
(Today R75 is easily available online.)
IRS has a lot of information from W-2 and 1099 filings, but it’s not possible to quickly and easily get that. A FOIA or Privacy Act request would probably not be processed in time to be useful for a tax return, and it might raise suspicion. Mailing all the reported information to taxpayers, without pre-filling a tax return, would be a good first step to making tax time easier in the US.
As such fraud creeps in.
You pay Inuit because there are nearly eighty thousand pages of tax law that even IRS workers cannot properly comprehend all because politicians use the IRS as a political tool to benefit those they like and punish those they don't.
Hence why any attempt to overhaul the tax process is quickly denounced by supposed neutral groups; groups at the beck and call of powerful political interest. There is an entire FUD industry built to keep the current system to benefit of the political class and those well off enough to pay them.
Intuit is one if the powerful political interests you refer to, an integral part of the FUD system you talk about built to keep the current system as-is for their own benefit.
Intuit is a convenient fall guy and nothing more. The real threat is that if the system were simpler and more open it could not be used to political advantage.
The real problem is that the US tax code is horribly, unnecessarily complicated.
Also, I believe mortgage interest is reported to the IRS.
Well, there is a reason, and is that tax preparation software and services companies spend lots of money lobbying Congress to keep the existing system since simplified filing would kill much of their business.
All those other forms are the same way. 1098s and 1099 are sent to the IRS at the same time they are sent to the taxpayers. The IRS takes who knows how long to process those forms from all the various generators, and it is highly likely that most people are done with their tax returns before the IRS gets to the forms submitted by the banks and brokerages. Same thing again for W2s.
So yes, the IRS has all this information. Eventually. They do not have it by the deadline they set for people to make their tax accounts right.
To the extent that is true for some information simply due to filing and delivery deadlines and processing times for various forms, the policy changes necessary to rectify it are fairly trivial to implement alongside any provision allowing IRS precomputation.
Because you choose to?
