Ha, no, the CPA does not need to enter transactions by hand.Most CPAs probably have software that would import Betterment's .csv formatted tax info, if desired. But most CPAS wouldn't even go to the trouble - they'd just print out your Betterment tax form and attach it to your return (this is what I've seen them do).Betterment produces your tax forms for you, and summarizes them neatly, with the few numbers you have to enter highlighted. The schedules you print include everythign the IRS needs, so you attach them. This assumes you do all your ETF investing with us - as of course you should, since we work best when we manage all your money (more tax efficient). I do my taxes myself, because they're simple (thanks to keeping all my investments at Betterment), and I used Betterment's .csv export and TaxAct software, which is cheaper and faster than the alternatives (in my unscientific opinion).I have heard one or two customers complain that our tax forms were long in past years. I'm sensitive to that issue - we've taken some steps to reduce their length, by cleverly combining transactions where there was no tax or cost disadvantage to doing so.I have to give the required disclaimer: don't take this post as tax advice and you should consult a professional tax advisor for any tax prep questions. There you have it.
