I agree with John's insight that it is wise to pay attention to what Block is doing--they have the resources to do the number crunching and projections. I think that the upcoming season will be booming for everyone due to all the confusion, but once people get the realization that itemizing won't do them any good and their refunds are shrinking due to lower withholding, that business will drop off.
I read Block's conference call transcript, and there's a lot more going on. Interestingly, millennials comprised something like 35% of their new business--evidence that young people are now working and don't have time or inclination to learn taxes or attempt their own? I think the office closures are a response to competition. Back in the heyday of RALs, Jackson Hewitt and Liberty were opening offices wherever they saw Block's busiest offices. And where they opened anywhere else, Block opened to lure traffic away. Those days are over and Liberty in particular is losing franchisees, closing offices, and may be delisted. No need to have all those offices so close to one another if a competitor is gone. Block said most of the closures are within five miles of other Block offices, more like the distance used to be before they decided to out-office the competition.
Block does know something, which is why they were on a mission to buy out small independents. Are they still doing that? They knew for some time that software would replace the easy-return market, and this week they acknowledged that they will do something about pricing. Didn't say which direction they would move prices, but they do charge a lot and likely can't see a way to justify the fee when a large share of their clientele no longer will itemize.
When I worked there years ago, they said that changes in the tax law drew a lot of business. They staffed accordingly, and they were always right. I think this upcoming season will be crazy busy for all tax preparers. While those who no longer itemize may DIY after that, I don't think anyone who is self-employed (including the part-time gig folk, those who sell occasionaly on the internet, etc) will ever attempt their own return. Ditto for landlords. And with the magnitude of the changes under the new law, I believe a lot of preparers who were thinking about retiring will just do it rather than try to learn all the new rules and unlearn the old ones. That too will drive more business to those who stick it out.
