Right. Two observations:
1) Like we've found so often in the past, the folks here aren't representative of the public at large.
2) This poll is going to find the "mode" of those who respond (i.e. the most frequent response--either "got more" or "got less"). The IRS press release discussed the "mean" refund. If the poll here shows most respondents got a lower refund, it's still very possible that the average (mean) of all refunds among respondents is higher than in 2017.
I agree. I suspect those of us that file later have more complicated returns and didn’t expect large refunds due to our tax planning. My cpa called me today and I am 38 refund in federal and owe state 200. He has emailed me my info to look over but I won’t have a chance to look at it until Monday. Once I smoke everything over I will share if overall taxes under the new system was more or less than before.
