If you ask most business owners what taxes they pay, the answer is usually the same:
- Income tax
- Capital gains tax
And while those are certainly real, they are only part of the picture.
In reality, successful business owners face six different taxes that can erode their wealth over time. Some show up every year. Others appear only during major financial events. And one of them isn’t even imposed by the government.
The real issue is not that these taxes exist. The issue is that most business owners never plan for them.
The better your business performs, the more complex your tax exposure becomes. Without a clear strategy, you can end up paying far more than necessary.
Let’s break down the six taxes every business owner eventually faces and how proactive planning can turn tax surprises into strategic decisions.
Quick Summary: The 6 Taxes Business Owners Pay
- Ordinary Income Tax: Levied on W-2 wages and business distributions.
- Capital Gains Tax: Triggered when selling a business, real estate, or stocks at a profit.
- Net Investment Income Tax (NIIT): A 3.8% surtax on passive investment income for high earners.
- Self-Employment Tax: A 15.3% tax covering Social Security and Medicare for self-employed individuals.
- Estate Tax: A tax on the transfer of business assets and personal wealth after death.
- The Behavior Tax: The financial losses caused by emotional investing and lack of financial planning.
1. Ordinary Income Tax for Business Owners
The most obvious tax business owners pay is income tax.
This applies to:
- W-2 wages from your company
- Owner compensation
- Schedule C income for sole proprietors
Income taxes can include both federal and state taxes, depending on where you live.
The federal system uses marginal tax brackets, meaning your business income is taxed in progressive layers rather than a flat rate.
For example:
- 10%
- 12%
- 22%
- 24%
- 32%
- 35%
- 37%
Each portion of income falls into a different bracket.
This is why your marginal tax rate and your effective tax rate are not the same.
Your marginal rate is the highest bracket you fall into.
Your effective rate is the average rate across all income after deductions and credits.
Another common misunderstanding among business owners is assuming that cash flow equals taxable income.
It does not.
Many tax deductions and accounting rules change the relationship between money coming into your bank account and what the IRS considers taxable income.
Examples include:
- Depreciation
- Bonus depreciation
- Section 179 deductions
- Business write-offs
You might generate large cash flow while reporting relatively modest taxable income.
Or the opposite can happen.
Understanding that distinction is essential when planning for taxes.
2. Short-Term and Long-Term Capital Gains Tax
Capital gains taxes occur when an asset is sold for a profit.
This could include:
- Real estate
- Stocks
- Cryptocurrency
- A business sale
Capital gains are calculated based on the difference between your cost basis and the sale price.
Example:
- Purchase property for $500,000
- Sell for $600,000
- Capital gain = $100,000
You only pay tax on the gain.
Capital gains fall into three federal brackets:
- 0%
- 15%
- 20%
However, these brackets stack on top of ordinary income.
This means your regular income determines where your capital gains begin to be taxed.
Another key distinction is short-term vs long-term capital gains.
If you hold an asset:
- Less than 12 months → taxed as ordinary income
- More than 12 months → taxed at long-term capital gains rates
For many business owners, this difference can mean paying 37% instead of 20%.
That is why timing matters.
Through professional exit planning, simply waiting a few weeks or months before selling a business asset can significantly reduce taxes.
This is a common planning opportunity many investors overlook.
3. The 3.8% Net Investment Income Tax (NIIT)
The Net Investment Income Tax (NIIT) is one of the most misunderstood taxes affecting successful individuals.
It adds an additional 3.8% tax on certain types of investment income.
The thresholds are:
- $200,000 for single filers
- $250,000 for married couples
Once income crosses those levels, the NIIT applies to passive investment income, including:
- Capital gains
- Rental income
- Dividend income
- Interest income
For example:
If a married couple earns $200,000 in ordinary income and has $100,000 in investment gains:
- The first $50,000 is below the threshold
- The next $50,000 may be subject to the extra 3.8% tax
So a 15% capital gains rate becomes 18.8%.
Many business owners do not realize this tax exists until they see the final tax bill.
There is one important exception.
If you actively participate in a business, income from selling that business typically does not trigger NIIT.
This is why tracking time spent in a business and documenting active participation can be extremely important.
4. Self-Employment and Payroll Taxes (FICA)
Self-employment tax often surprises new business owners.
When you are self-employed, you effectively pay both sides of payroll taxes:
- Employer portion
- Employee portion
Combined, this equals 15.3%.
This tax covers:
- Social Security
- Medicare
For sole proprietors, this tax can apply to all earned income.
For S-Corporations, it generally applies only to W-2 wages, not distributions.
This is why entity structure matters.
Some business owners unknowingly operate as sole proprietors while earning significant income, paying self-employment taxes on the entire amount.
In contrast, an S-Corporation may allow income to be split between:
- Salary (subject to payroll taxes)
- Distributions (not subject to payroll taxes)
However, salaries must still be reasonable compensation under IRS rules.
Choosing the correct business structure, such as an LLC versus an S-Corporation, can dramatically reduce your self-employment tax exposure.
5. The Federal Estate Tax on Business Wealth
Estate tax is often ignored during a business owner’s working years.
But it can become one of the largest taxes ever paid on your wealth.
Estate taxes apply when assets are transferred after death.
As of recent law changes, the federal estate tax exemption is approximately:
- $15 million per person
- $30 million per married couple
Any amount above that threshold may face a 40% estate tax.
Some states also impose additional estate taxes.
For business owners who build valuable companies, this tax can become a major issue.
Without planning, heirs may be forced to:
- Sell business interests
- Liquidate investments
- Borrow funds to pay the tax bill
Working with a fiduciary advisor on estate planning strategies can help reduce this burden, including using:
- Trust structures
- Family limited partnerships
- Grantor trusts
- Strategic gifting
- 529 education planning
Estate planning is not just for billionaires. For many successful business owners, it becomes essential long before retirement.
6. The Behavior Tax: The Hidden Cost of Bad Planning
The final tax is rarely discussed, but it is often the most expensive.
This is the behavior tax.
It has nothing to do with the IRS.
Instead, it comes from poor financial decisions.
Examples include:
- Overconcentration in a single investment
- Panic selling during market downturns
- Overspending and running out of liquidity
- Ignoring diversification
- Failing to plan for major tax events
These mistakes quietly destroy wealth over time.
In many cases, the hidden cost of the behavior tax exceeds the actual taxes paid to the government.
The behavior tax is essentially a transfer of wealth caused by poor decision-making.
Avoiding it requires discipline, planning, and objective advice.

For business owners focused on building long-term wealth, understanding these taxes is not optional.
It is essential.
Because the real question is not whether you will pay these taxes.
The real question is how much you will pay — and how much you keep.
Most business owners only think about taxes when their CPA sends the bill.
By then, it’s too late to do anything about it.
The best tax strategies happen before the event occurs, not after.
