President Donald Trump and Treasury Secretary Steve Mnuchin have targeted April 6. Tax experts (and lawmakers working on this) are very skeptical of that date. There’s no question they want — and need to turn this around — ASAP. There are also different ways it could be done — through direct deposit (which would be the quickest delivery mechanism), through mailing a paper check or even, according to some people involved in the discussions, through mailing pre-loaded debit cards. But the reality is there isn’t a firm answer yet. In other words, Treasury has a lot of work ahead of it.
