The Tax Laws are not simpler - but for most people they are.
It has been reported that the number of people itemizing deductions has shrunk from 25% to 8%. I believe that means the IRS can avoid complicated returns and process most people's taxes simply by compiling information returns. They have been at war with itemized deductions my entire career - the standard deduction was called "low income allowance" and hardly anyone took it back then.
An increasing number of taxpayers can now very easily file taxes themselves, online, or TurboTax.
I am recommending for taxpayers to engage in a sideline business, or buy rental property, or otherwise complicate things. Not so I can continue with their tax preparation, but for their own benefit to deduct expenses that are now lost. And I expect in the near future, the IRS will swoop down and reclassify legitimate consulting businesses to employees.
I have enough clientele left to sustain me - for most of mine have rental property, small business, exotic investments, etc.
But as an industry, I see a shrinking customer base. One telling look-around at CE seminars reveal most people at those seminars are 55 or older. It is a new year, and we've got to pay attention to handwriting on the wall.
