How Can Business Owners Reduce Tax Before They Sell?

Selling a business is likely the largest financial transaction you'll ever make. And for most business owners, the tax bill that comes with it is the biggest surprise,because they didn't plan for it early enough.

The strategies that meaningfully reduce your tax burden on a business sale need to be in place years before you close. Here's what every owner should understand.

This post is part of our guide to business exit planning for Colorado owners.

First: Understand What You're Selling

How your sale is structured has an enormous impact on your taxes. There are two primary structures:

Asset Sale

The buyer purchases the individual assets of your business,equipment, inventory, customer lists, goodwill. Most buyers prefer this because they get a stepped-up tax basis on assets. For sellers, portions of the proceeds may be taxed as ordinary income (on items like inventory and depreciation recapture) and portions as capital gains (on goodwill and other intangibles).

Stock Sale (or Membership Interest Sale)

The buyer purchases your ownership stake directly. Sellers generally prefer this because proceeds are more likely to be taxed at long-term capital gains rates,significantly lower than ordinary income rates. Buyers tend to resist this structure, which is why understanding your negotiating leverage matters.

The difference between an asset sale and a stock sale can easily be worth hundreds of thousands of dollars in taxes on a $2M+ transaction. This is not something to sort out at the closing table. It needs to be part of your exit strategy years in advance.

Six Strategies to Reduce Your Tax Bill Before the Sale

1. Hold for Long-Term Capital Gains

If you've owned your business (or a portion of it) for more than one year, proceeds from the sale of your ownership interest may qualify for long-term capital gains rates,currently 0%, 15%, or 20% depending on your income, versus ordinary income rates that can reach 37% federally. Make sure your ownership timeline is clearly documented. For 2026, the 20% federal rate applies to married couples filing jointly with taxable income above $613,700, and the 3.8% net investment income tax may also apply depending on your role in the business. Colorado taxes capital gains at its flat income tax rate, 4.4% as of this writing.

2. Qualified Small Business Stock (QSBS) Exclusion

If your business is a C-corporation and meets certain requirements, Section 1202 of the tax code may let you exclude some or all of your gain on a sale. For qualifying stock issued after July 4, 2025, the exclusion is 50% after three years, 75% after four years, and 100% after five years, up to the greater of $15 million or 10 times your basis per company. Stock issued on or before July 4, 2025 generally follows the prior rules: a five-year holding period and a $10 million cap. The company's gross assets generally cannot exceed $75 million when the stock is issued ($50 million for stock issued before the change), and many service businesses, including health, law, accounting, consulting, and financial services, do not qualify. If you convert an S-corporation or LLC to a C-corporation, only stock issued after the conversion can qualify, and the holding period starts then. Eligibility has to be established well before a sale.

3. Installment Sale

Rather than receiving all proceeds at closing, an installment sale spreads payments over multiple years. This lets you spread the taxable gain over time, potentially keeping you in lower tax brackets each year and deferring part of the tax bill. It also introduces risk,you're essentially financing part of the deal,so structure matters.

4. Charitable Planning Before the Sale

Donating appreciated business interests to a Donor-Advised Fund (DAF) or Charitable Remainder Trust (CRT) before a sale can allow you to avoid capital gains on the donated portion while generating a charitable deduction. This works particularly well for owners with philanthropic goals who want to give intentionally rather than reactively.

5. Maximize Retirement Contributions in Pre-Sale Years

In the years leading up to a sale, aggressively funding retirement accounts,Solo 401(k), SEP-IRA, defined benefit plan,reduces your taxable income and moves money into tax-advantaged growth. Depending on your age, income, and plan design, a defined benefit plan may allow deductible contributions of $100,000 or more per year. These plans come with ongoing funding obligations and administrative costs.

6. Entity Structure Review

The entity type you operate under,S-Corp, C-Corp, LLC,significantly affects how sale proceeds are taxed. In some cases, converting from one entity type to another several years before a sale can unlock better tax treatment. This is not a last-minute decision; the IRS has holding period rules that apply.

The Timeline Problem

Here is the timing problem: by the time you are in active sale negotiations, many of these strategies are no longer available.

QSBS eligibility has to be established years earlier. Entity conversions need time to season. Charitable planning is most effective before a sale becomes imminent. Many of these strategies work best when planning starts three to five years before a sale, not three to five months.

What Exit Planning Looks Like

At Balanced Wealth Partners, our exit planning process starts with three questions: When do you want to leave? How much do you need from the sale to fund the rest of your life? And what does your business need to look like,financially, operationally, and legally,to get there?

Tax strategy is woven into every stage of that process. We work alongside your CPA and attorney,not instead of them,to make sure your plan is coordinated across every dimension.

As a Certified Exit Planning Advisor (CEPA®), Chase works with business owners to build exit roadmaps that integrate financial planning, tax strategy, and business value optimization, years before the sale. Before choosing a strategy, it helps to know what your business is worth and how much you need from the sale.
