Our federal tax code is a disaster.
It's a bureaucratic nightmare, requiring armies of CPAs and lawyers to navigate. It's a damper on growth, imposing penalties on positive behaviors like research and offering harmful special breaks for bad things like coal extraction. It's a distributional mess, imposing higher rates across the board to make room for an endless litany of lobbyist-extracted carveouts and loopholes. Worst yet, it's not getting better; it's getting worse.
Politicians of all stripes are constantly promising even more complexity on the campaign trail. There is little more fashionable on the Hill than a new tax credit, deductions, exclusion, or exemption. These tax expenditures (as they are collectively called) never cease to fail to solve the problem they are aimed at, yet have been deployed ambitious and bipartisanly for decades.
To point to one timely example, our newly elected President Trump proudly campaigned on creating new exclusions for overtime pay, tips, and even things as marginal and specific as car payments. Needless to say, these changes would add more intricacies to our already endlessly spanning pages of code.
Earlier today, I was pondering this fact as a thought jumped into my mind: "I wonder exactly how many tax expenditures there are and how much they cost in total?" It didn't take long for me to find the answer. Thankfully, the Department of Treasury makes the data on tax expenditures readily available on its website.
From their data, there appear to be 169 tax expenditures in total, costing the United States over $1.5 trillion dollars last year. This is a truly whopping sum—nearly equivalent in size to Social Security. I've listed them here so you can look at each one for yourself.

Clearly, not all of these can or should be eliminated, but the vast majority should. To point to just three opportunities for consolidation:
Our fragmented array of complicated healthcare tax breaks, which are far from guaranteeing universal affordable access to care, would be better replaced with a single simple health insurance subsidy, done external to the tax code.
Our various accelerated depreciation schemes and special investment tax breaks would be best replaced by a blanket deduction for all investment costs of all varieties (full expensing).
Our litany of tax exclusions for government-provided benefits would be better replaced by a single large tax exclusion for all government-provided entitlement benefits.
Simplicity does not require us to abandon the aspirations of our tax code, nor does it require us to give up progressive tax brackets, as many on the right have claimed. What it requires is taking up a large and politically challenging task, one that will put us at odds with a powerful army of special interest groups.
Difficult as that might be, it's a worthwhile priority and one essential for curbing the unsustainable budget deficit we are currently faced with.
Nothing is certain, save for death and taxes. 100 percent agreed with you Micah. There is simply no reason to further "complexify" an already unfathomably complex tax code.
At this point, it doesn't appear that anyone has the gumption to do what is necessary and set the code on fire and start anew.
We best ought to begin moving to consumption taxation and reducing tax on production. A VAT would be a good place to start, alongside an LVT. Simpler administration, harder to evade, and more economically efficient on several fronts.
The question is, why is the tax code getting more complicated? If you were to poll people and ask them whether they want a simpler or a more complex code, everyone would choose the former.
This reminds me of the situation in universities. If you had asked people 40 years ago whether universities should hire more professors or more administrators, of course they’d all said more professors! Yet here we are.
