I've used the same CPA since 1977. Most years I probably could do it myself, but every few years something comes up that would complicate things. Like settling my moms estate, or last year, with my wife and I retiring.
My CPA says the fastest growing portion of his business these days is fixing tax returns prepared in Turbotax.
Of course the IRS being slow to clarify deductions doesn't help. Here in California we all got $700 gasoline tax rebates, and the IRS still hasn't said if that is taxable, so basically anyone here is in a holding pattern on filing their taxes until that gets resolved.
I miss doing it on paper. As mine have never been complicated, only itemizing a few times and never more than 1 or 2 W2 forms, it was so much easier to fill out what you knew you had to fill out compared to software and having to click through countless screens, usually 1 item or line per screen, that I don't need to do anything with. It takes me forever to do them with software with only 1 W2 and nothing else.I currently use TurboTax, which makes it easier than when everything was hand calculations on paper forms. Just acquiring all the forms needed by everyone used to take some doing. Especially when unexpected surprises in others’ filings popped up for a given year!
I'm sure that's true (that you deal with mistakes). But I doubt the majority of taxpayers can't handle taxes themselves or with online software. I have gotten letters from the IRS a couple of times and dealt with it myself. (The IRS was wrong both times.) I pay attention to tax law changes and am very comfortable with our situation.It's amazing the amount of work we get fixing self prepared returns for returns prepared at someone's kitchen table (that people actually pay for).
More often than not, when someone makes a mistake or an omission that's in the favor of the IRS/DOR, they won't hear anything about it, so they assume no mistakes were made. However, if there's a mistake against the IRS/DOR then they get a letter, and that's when our phone rings. It's amazing how much people actually leave off that they would otherwise be able to reduce their tax liability resulting in a larger refund OR less owed.
