By never having paid the IRS before, I'm assuming you've never had to pay over what was already taken from your paycheck and pension checks. Anyway, what I'm about to say is not a political statement, it's simply the facts. The top 50% of earners in the USA pay more than 90% of the taxes. It's that simple. And the more income you earn, the percentage of that income that they take from you escalates in a non-linear fashion. I owned a business in a low-tax State and I had every conceivable deduction you could mention and I still ended up paying 20% of my income in taxes. The only way to pay less tax, is to earn less money, earn money that is taxed at a lower rate, like capital gains, or earn money outside the US. Of those three options, the only desirable and practical one is to earn money that is taxed as capital gains. While I think you should consult a tax professional to save as much as you can. That doesn't fix the real issue, which is the rate you pay. In order to earn more from capital gains, you need to consult an investment professional that can help you find and invest in income-producing investments that are taxed as capital gains. Dividend stocks, alternative investment category vehicles like, BDCs, MLPs, closed-end funds, venture capital firms, and REITs are some examples. Something I think is a very attractive income investment is real estate. But investing in RE is far outside the scope of this discussion. All-in-all, either make less or learn to make more through means that are taxed at a lower rate. Now, to illustrate how impactful this is, if your total income is less than $47,000, you pay no capital gains tax. If you earn between $47,000+ and $519,000, your CG rate is only 15% and anything above $519,000 is taxed at 20%. So, the greater percentage of your total income that is classed as capital gains, the lower your overall tax burden will be. Ideally, you'd want all your income to be from capital gains. You should - if feasible - consider moving to a State with no State income tax.
All the best.
