In case you missed it—because of the recent flurry of activity in Congress and the administration, followed by lawmakers quickly skipping town for the Easter recess—Tuesday was Tax Day.

We’ll pause for you to file your taxes or ask for an extension (remember you have to pay any taxes due even if you get an extension).

But if you want to amend your taxes, we have some ideas on how you could save big. Sure, you’d have to incorporate, but that’s the hardest part. Turns out there are some lucrative tax breaks that you don’t have to do much for, and the returns could be great (for you, pretty bad for the rest of us tax-paying folks). And with the cuts to the IRS, who is going to audit you?

Here are a few tricks that TurboTax or your H&R Block tax advisor probably missed:

Ever think about getting in the transportation fuel production game? This might be the perfect time to start, since it is the first year the IRS is offering a tax credit of up to $1.75 per gallon for so-called sustainable aviation fuel and up to $1 per gallon for other fuel that meets certain greenhouse gas emissions requirements. The Department of Treasury is estimating $3.6 billion in 45Z Clean Fuel Production Credits will be claimed this fiscal year alone, with that number rising to $5 billion next year and $5.5 billion the year after that. And the tax credit may be getting even more lucrative—and more expensive for American taxpayers—as the IRS recently proposed expanding eligibility, which would allow more producers to claim 45Z under less stringent emissions requirements. Sure, producing transportation fuel requires a big investment, but there are other federal subsidies available (like the Bioenergy Program for Advanced Biofuels) and even a federal mandate (called the Renewable Fuel Standard) that requires transportation fuel refiners blend a certain amount of biofuels every year.

Any chance you’re a race car driver or want to pick up a new hobby? NASCAR track owners get to write off their investments ahead of schedule. This accelerated depreciation—seven years for any “motorsport entertainment complex”—means that track owners can write off improvements to their facilities, reducing their taxable income, in less than half the time most other investors do with similar real estate. So too for film, television, and stage productions. And the owner of next month’s Kentucky Derby winner can depreciate that horse this year even though it clearly has a far longer economic life than the three years suggested by the U.S. Tax Code.

Maybe you’re still taking advantage of some pandemic-era breaks that live on? The Employee Retention Credit created during COVID is still on the books and ripe for abuse well after the pandemic. Latest estimates suggest more than $200 billion in credits have been claimed, with some projecting that price tag to grow to a whopping $550 billion if left untouched. And an IRS review last year found the vast majority of claims appear to be fraudulent—as much as 90 percent.

How about structuring your business instead as a pass-through entity, like a sole proprietorship, partnership or S-Corporation so you can report profits and losses on your personal tax return? That gets you 20% deduction on your business income. This provision (199A) is projected to cost the Treasury nearly half a trillion dollars over a decade.

Interested in investing in carbon capture and storage (CSS) infrastructure—designed to capture carbon emissions from power plants, industrial processes, or directly from the air? While studies have shown that constructing and operating CCS is prohibitively expensive and may even crowd out investments in smarter energy solutions, the federal government still offers up to $36 per metric ton of carbon oxide captured and stored. The Treasury Department estimates $530 million in 45Q Carbon Sequestration Credits will be claimed this fiscal year, with that amount more than quadrupling in just four years (to $2.5 billion in fiscal year 2029). Much like “sustainable” transportation fuel, there are also billions of dollars in other government subsidies available for CCS, including funding for research and development and taxpayer-backed loan guarantees.

Want to join the latest energy craze, hydrogen has certainly been getting a lot of hype on Capitol Hill and plenty of federal subsidies to boot. The 45V Credit for Production of Clean Hydrogen offers a four-tier production incentive of up to $3 per kilogram of hydrogen and can be claimed for 10 years, as long as facility construction begins before 2033. The credit is anticipated to cost taxpayers $860 million this fiscal year and ten times that by 2032 ($8.9 billion). While the final rule is supposed to ensure hydrogen production doesn’t divert existing renewable energy from the grid—which could otherwise lead to increased fossil fuel use elsewhere—there are plenty of exemptions for nuclear plants, CCS, or facilities in states with robust clean electricity standards.

Or maybe you are looking for a second job? If you decide to work as an investment manager, you can take advantage of the carried interest loophole and treat your salary (income) as capital gains instead and get a lower tax rate. Don’t forget capital gains are taxed at 15 or 20 percent (depending on your income), which will reduce federal tax revenues by more than $200 billion this year.

As you can tell, we could go on.

Truth is, we’re not giving tax advice. We actually think these breaks—and many others across the tax code—squander tax revenue without providing equivalent benefits to taxpayers. Every year, taxpayers spend billions of dollars in subsidies across economic sectors, many of which work at cross purposes, subsidize activities that are inefficient, distort markets, or increase pollution.

Tax Day is not the only reason we should be mindful of the billions of dollars in subsidies going out the door this year—policymakers are also planning a massive budget reconciliation package and looking for cuts that can help offset the cost. Paying for $4.5 trillion in extended tax cuts is no easy task, and hiding behind accounting gimmicks is not the answer.

Our national debt is more than $36 trillion, with annual interest to service the debt at $1 trillion and rising. The serious fiscal crisis facing our country requires serious solutions. Adding these tax subsidies to the chopping block may not be enough, but it would be a start.
