A practical guide for Illinois business owners who want their life’s work to stay in the family
If you’ve spent decades building a business, you’ve probably had that thought late at night: What happens to all of this when I’m gone?
It’s a heavy question. And if you’re like most business owners we meet, you might be putting off the answer because it feels overwhelming. Maybe you figure your kids will work it out. Or that a simple Will covers it.
We get it. But here’s the hard truth we need to share: without the right planning, even a thriving business can be forced to close its doors just to pay the tax bill after you pass away. That’s not meant to scare you; it’s meant to help you protect what you’ve built.
The good news is that with some smart planning now and an experienced Small Business & Corporate Law team, you can protect both your business and your family’s financial future.
The Hidden Pitfalls of Family Business Succession
Many business owners assume that leaving their company to their children in a Will is enough. Unfortunately, this approach often creates more problems than it solves.
Estate Tax Exposure
In 2025, the federal estate tax exemption is generous, but it’s scheduled to drop significantly in 2026. For Illinois business owners, there’s an additional concern: Illinois has its own estate tax with a much lower threshold (currently $4 million). If your business is valued above this amount—and many successful small businesses are—your heirs could face a substantial tax bill before they even take ownership.
Liquidity Crisis
Even if your business is worth millions on paper, that doesn’t mean your heirs will have cash on hand to pay estate taxes. The IRS typically wants payment within nine months of death. This timeline can force families to sell business assets, take out loans, or even liquidate the entire company just to satisfy the tax obligation.
Family Conflict and Unclear Ownership
What happens when you leave your business equally to three children, but only one has been actively involved in operations? Or when one heir wants to sell while another wants to continue the family legacy? Without clear succession planning, these disagreements can tear families apart and destroy the business in the process.
Valuation Disputes
The IRS may value your business differently than you do. Without proper documentation and planning, you could face challenges that inflate the taxable value of your estate, resulting in higher taxes than necessary.
Loss of Key Relationships
Customers, suppliers, and employees need to know the business is in stable hands. A chaotic transition can cause key relationships to crumble, taking your business’s value with them.

How to Make Succession Smooth
Illinois law provides several powerful tools to help you pass down your business efficiently while minimizing taxes and family conflict.
1. Trusts: The Foundation of Smart Business Succession
Revocable Living Trusts
A revocable living Trust allows you to maintain control of your business during your lifetime while ensuring a smooth transition upon your death. Unlike a Will, a Trust potentially avoids probate—the costly and time-consuming court process that can tie up business assets for months or even years. This means your successors can step in immediately without disruption.
Irrevocable Life Insurance Trusts (ILITs)
One of the smartest strategies for business owners is pairing an ILIT with a life insurance policy. Here’s how it works: the Trust owns a life insurance policy on you, and when you pass away, the death benefit is paid to the Trust—not your estate. This means the insurance proceeds aren’t subject to estate tax, and your heirs have immediate liquidity to pay any taxes owed, buy out other family members, or invest in the business’s future.
Grantor Retained Annuity Trusts (GRATs)
For business owners looking to transfer wealth while minimizing gift taxes, GRATs can be incredibly effective. You transfer business interests into the Trust, receive annuity payments for a set term, and at the end of the term, the remaining assets pass to your heirs with minimal tax consequences.
Special Needs Trusts
If you have a family member with special needs who shouldn’t directly own business assets (due to government benefit eligibility), a properly structured special needs Trust can protect both their benefits and their inheritance.
2. Buy-Sell Agreements: Preventing Family Feuds
A buy-sell agreement is essentially a prenuptial agreement for business partners—including family members. This legally binding contract determines what happens to a business owner’s share when they die, become disabled, or want to exit the business.
Key Benefits:
- Fixed Valuation: The agreement establishes how the business will be valued, providing clarity for both the IRS and family members
- Guaranteed Buyers: Active family members or co-owners have the right (or obligation) to purchase the departing owner’s share
- Funding Mechanism: Often paired with life insurance to ensure buyers have the cash needed to complete the purchase
- Business Continuity: Prevents unwanted outsiders (like a son-in-law after a divorce) from gaining ownership
For family businesses, buy-sell agreements can be structured as:
- Cross-purchase agreements: Where individual family members buy each other’s shares
- Redemption agreements: Where the business itself buys back the shares
- Hybrid agreements: Combining both approaches for maximum flexibility
3. Strategic Tax Planning: Keeping More for Your Family
Annual Gifting
You can gift up to $19,000 per person per year (2025 limit) without triggering gift tax. For a family business, this means you can gradually transfer ownership to your children over time, reducing the size of your taxable estate. If you’re married, you and your spouse can jointly gift $38,000 per child annually.

Valuation Discounts
When transferring minority interests in a family business, you may be able to claim valuation discounts for lack of control and lack of marketability. This can significantly reduce the taxable value of transferred interests. However, these discounts must be properly documented and structured to withstand IRS scrutiny.
Installment Sales
Rather than gifting business interests outright, you can sell them to your heirs using an installment sale. This spreads out the tax impact and can be structured with favorable terms for family members.
Qualified Small Business Stock (QSBS) Exclusion
If your business is structured as a C-corporation and meets certain requirements, your heirs may be able to exclude up to $10 million (or 10 times their basis) in capital gains when they eventually sell the business.
Step-Up in Basis
When your heirs inherit your business, they get a tax advantage called a “step-up in basis.” In plain terms: if they decide to sell, they’ll only owe capital gains tax on growth that happens after they inherit, not on all the value you built over the years. This can save them a significant amount in taxes.
Illinois offers several strategies to help you pass down your business efficiently while minimizing taxes and family conflict.
Why You Need an Attorney Who Speaks Both Languages
Business succession planning works best when you have an attorney who understands both the operational side and the estate planning side. It’s about creating a cohesive strategy where your business structure, ownership agreements, and estate documents all work together.
The intersection of estate and business law is where comprehensive planning happens.
An attorney with experience in both areas can:
- Structure your business entity properly from the start, considering both operational needs and estate planning goals
- Coordinate your personal estate plan with your business succession plan so they work together seamlessly
- Navigate complex tax issues that span both business and estate tax law
- Draft operating agreements and shareholder agreements that complement your Trust and Will documents
- Advise on timing and strategy for transferring interests while you’re still active in the business
- Handle both the business and probate sides if estate administration becomes necessary
- Mediate family dynamics with an understanding of both the emotional and legal complexities involved
At M.W. Brady Law, we’ve built our practice around exactly this intersection. Every business is different. Every family is different. The farm that’s been in your family for four generations needs a different approach than the manufacturing company you started 20 years ago.
That’s why we treat every consultation as a conversation, not a sales pitch. We want to understand what you’ve built, what you want to happen to it, and what keeps you up at night. Then we can lay out the options in plain language and help you make the choices that fit your situation.
