The tax code in the United States is over 2,000 pages long.

Most people will never read a single page of it.

Buried inside those pages are legal ways for investors to keep more of their money. Actual rules the government created to reward certain types of investing, saving, and spending.

(For a broader look at legal tax-saving strategies, check out our full guide on 11 Ways to (Legally) Pay Less Taxes.)

This article covers the three types of income and how they're taxed, six strategies investors use to reduce their taxable income - from retirement accounts to real estate to tax-loss harvesting - and why having the right advisor matters more than any single deduction.

First, Understand the Three Types of Income

Before you can reduce your taxable income, you need to understand how income actually gets taxed. Not all income is created equal.

There are three general categories:

• Earned income - the money you make from your job. Salary, wages, and bonuses. It comes with the highest tax rates and the fewest deductions.
• Portfolio income - the money you make from stock market investments. This includes capital gains and dividends.
• Passive income - the money you make from things like rental properties and real estate investments. (This is also known as income investing - getting paid just for owning assets.)

If you're a worker at a company like Coca-Cola, your tax rate is roughly 15% to 24%.

A C-suite executive making $24 million? They're taxed at the highest rate - up to 37%.

But an investor like Warren Buffett - who earned $704 million in dividends in 2021 - his maximum tax rate on that income was only 20%.

Same economic system. Wildly different tax treatment. The tax code is structured to benefit investors - and the three types of income above are the reason why. (We break down how this system works in our guide to how a capitalist economy actually operates.)

Strategy 1: Use Tax-Deferred Retirement Accounts

The most accessible way to reduce your taxable income is through retirement accounts like a 401(k) or IRA.

These are tax-deferred retirement accounts - meaning the government gives you incentives to invest through them.

With a traditional 401(k) or IRA, you put in pre-tax money. You don't pay taxes on it today. Your money grows tax-free inside the account, and when you pull it out in retirement, you pay taxes then.

Every dollar you contribute lowers your taxable income right now.

A Roth 401(k) or IRA works differently. You contribute after-tax money - so less goes in. But your money grows tax-free and you can generally pull it out tax-free in retirement.

Which one makes more sense depends on one question: do you think your tax rate will be higher or lower when you retire?

Investors who plan to stack cash flow over time - through rental properties, dividends, or business income - may benefit from locking in today's tax rate with a Roth. Investors who expect less income in retirement may prefer to defer taxes with a traditional account.

One thing worth knowing: even the founder of the 401(k) has said publicly that it was never meant to be your only retirement vehicle. Get the company match if you have one, then build from there. (For a full breakdown on building toward a seven-figure retirement, read How to Retire a Millionaire.)

Strategy 2: Invest in Real Estate for Tax Breaks

Real estate has some of the biggest tax breaks the tax code offers. This is one of the main reasons wealthy investors own property.

Say you made $10,000 in profit from your rental portfolio after paying all expenses. Real estate investors can use something called the depreciation deduction - a paper write-off that lets you deduct a portion of your property's value every year, even if the property is going up in value.

You made the money. But you write off part of it on your taxes. So you pay less.

On top of depreciation, you also get to write off ordinary and necessary business expenses:

• Vehicle expenses to visit your rental properties
• Meals with brokers and property managers
• Travel to inspect potential investments
• Repairs, maintenance, and property management fees

When you earn income from a job, you make money, pay taxes, and spend what's left.

When you earn income from real estate, you can earn money, spend money on deductible expenses, and only pay taxes on whatever's left.

If you don't want to buy property directly, there are passive options too - real estate funds, syndicate deals, or crowdfunded real estate platforms. You still have risks. If the market drops or a deal goes south, you can lose money. But it's a way to access real estate tax benefits without operating properties yourself. (Weighing whether to buy or rent?

Strategy 3: Use Tax-Loss Harvesting in Your Portfolio

Tax-loss harvesting is one of the simplest strategies investors use to reduce what they owe - and most beginners have never heard of it.

Here's how it works.

Say you have Stock A that gained $5,000 and Stock B that lost $3,000. If you sell both, you only owe capital gains tax on $2,000 - because the loss offsets the gain. (For more on how capital gains taxes work and how to minimize them, see our guide on how to avoid capital gains tax.)

You can even carry forward losses to future years if your losses are bigger than your gains in any given year.

And you can immediately buy a similar (but not identical) investment to keep your market exposure. Sold an S&P 500 ETF at a loss? Buy a different S&P 500 ETF right away.

One rule to know: the wash sale rule says if you buy back the same or substantially identical security within 30 days, you can't claim the loss. Timing and selection matter.

This strategy works best in taxable brokerage accounts - not retirement accounts. Over time, it can save a significant amount on taxes. (Knowing when to sell a stock is just as important as knowing when to buy one.)

Strategy 4: Earn Income That's Taxed at Lower Rates

Not all investment income is taxed equally. Understanding the difference can save real money.

Qualified dividends - dividends from stocks you've held long enough - are taxed at preferential capital gains rates of 0%, 15%, or 20% depending on your income. That's much lower than what you'd pay on earned income from a job.

Companies known for paying consistent, growing dividends - like Dividend Aristocrats and Dividend Kings - are popular among investors looking for qualified dividend income.

Ordinary dividends are taxed at your normal income tax rate. So the type of dividend matters.

This is also why long-term investing has a built-in tax advantage. Holding a stock for over a year before selling means your profits are taxed as long-term capital gains - which carry lower rates than short-term gains.

The tax code rewards patience. The longer you hold, the less you typically owe.

Strategy 5: Start a Business and Write Off Expenses

When you have a business, the tax equation flips.

As an employee, you earn money, pay taxes, and spend what's left.

As a business owner, you earn money, spend on deductible business expenses, and pay taxes on what's left.

Business owners can deduct ordinary and necessary expenses - things like equipment, software, office space, travel, and professional services. During the pandemic, the government passed Section 179 rules that allowed business owners to write off up to 100% of certain heavy vehicles used for business.

But the important part isn't the deduction itself. It's how you use it.

Don't spend money just to spend it. A $150,000 purchase that doesn't generate any income isn't a smart move just because it's deductible. A smart tax strategy means spending money in a way that adds value to your business - while also reducing your tax bill. (Understanding the difference between good debt and bad debt can help you think about which expenses are actually worth taking on.)

Strategy 6: Get a Tax Advisor Who Does More Than File

If all your tax advisor does is file your taxes, you're leaving a lot of money on the table.

Filing is the bare minimum. What you actually want is tax planning and tax strategizing - meeting with your advisor about what you can do with your money today, based on the deductions available right now.

The tax code is a rule book. The investors who win the tax game are the ones who understand the rules. And to understand those rules, a good advisor is essential. (Building a team of advisors is a key part of wealth planning - and it goes beyond just taxes.)

This is especially true for investors in real estate or anyone building a business. A good tax advisor will help structure your finances so you pay the least amount in taxes - legally.

The IRS tax code is 2,000+ pages. You don't have to read it yourself. That's what your team is for. (If you're still building your financial literacy, learning how tax strategy fits into the bigger picture is one of the highest-value skills you can develop.)

The Bottom Line On Reducing Taxable Income

Reducing your taxable income isn't about gaming the system. It's about understanding it.

The tax code was written to reward investors, business owners, and people who plan ahead. Every strategy above is legal, accessible, and available to anyone willing to learn the rules.

The money investors save through smart tax strategy can be substantial. Way more than the cost of getting a little help.
