Here’s a conversation we have too often.

A family business owner calls. The founder is 68, wants to hand things over to their kids in the next five years, and wants to know what they need to do.

We ask when they started thinking about it.

“This year,” they say.

That’s the problem.

The Short Answer: Succession Tax Planning Has a Shelf Life

The biggest tax-saving strategies in a family business transition — gifting appreciated assets, installment sales, GRATs, family limited partnerships — only work if you have time. Years, not months.

If you start planning two years out, you’re not too late. But you’ve probably already given up six figures in tax savings you didn’t know you were leaving on the table.

This post covers the four most common tax mistakes family-owned businesses make during succession — and the specific moves that only work if you start early.

Mistake #1: Waiting Until the Founder Is Ready to Retire

Most owners start succession planning when the founder decides they’re done. That feels logical. It’s backwards.

Succession tax planning works best when the business value is growing — not when the founder is mentally checked out and the business has plateaued. Gifting strategies, installment sales, and ownership restructuring all depend on where the business is valued today versus where it’ll be when you actually transfer it.

If you wait until the founder is ready, you’re usually transferring at peak value — which means maximum tax exposure.

What works better: Start conversations about ownership structure 5–10 years before the intended transfer. The strategies don’t require any action that soon — but they require that much runway to implement properly.

Mistake #2: Skipping the Valuation Until the Last Minute

Every succession plan lives or dies on the business valuation. And most families get their first serious valuation 12–18 months before they need it.

That’s too late to do anything with the number.

A good valuation done early does three things. It tells you what you’re actually working with. It identifies whether there are legitimate reasons the number could be lower (which matters for gift tax and estate tax planning). And it gives your CPA time to structure the transfer in a way that works with that number.

Valuation discounts — for lack of control, lack of marketability — are legitimate and legal planning tools. But they require documentation, defensible methodology, and time. You can’t manufacture them at closing.

Mistake #3: Treating the Estate Plan and the Business Plan as Separate Documents

Most family business owners have an estate plan. Most have a business succession plan. Very few have one that talks to the other.

When the estate plan and the business transfer plan aren’t integrated, you end up with situations like: a buy-sell agreement that conflicts with the will, a surviving spouse who inherits a minority interest in a business with no liquidity provision, or kids who get equal ownership of a business they can’t equally run.

These aren’t rare edge cases. They’re the default outcome when the estate attorney and the business CPA never sit in the same room.

The fix isn’t complicated — it’s just coordination. Your CPA, your estate attorney, and if relevant your financial advisor need to review both documents together. Once. Before anything is finalized.

Mistake #4: Not Using the Business’s Income to Fund the Transition

Families often think of succession as a transfer event — a single moment when ownership changes hands. In reality, the most tax-efficient successions are designed as processes, often spanning 5–10 years.

One underused approach: using current business income — through salary, distributions, or structured buyout payments — to gradually fund the transition. This can reduce estate exposure, minimize gift tax, and give the next generation time to build equity without a lump-sum capital event.

Whether this fits your situation depends on your structure, your family dynamics, and the business’s cash flow. But if nobody’s asked you about it yet, ask them why not.

What This Means for You

If you own a family business and succession is in the next 10 years — even loosely — here’s the short version:

• The tax-saving moves disappear the longer you wait.
• Valuation discounts, gifting strategies, and installment structures all require runway.
• Your estate plan and your business plan need to be in the same room at least once.
• You don’t have to start a formal process today — but you should at least have the conversation.

We work with family business owners across Illinois and Wisconsin on exactly this kind of planning. If you’re not sure where you stand, a single conversation with a Client Advisor is worth a lot more than it costs.

Frequently Asked Questions

When is the right time to start succession planning for a family business?

Earlier than you think. The most effective tax strategies for family business transitions require 5–10 years of runway. If the intended transfer is within the next decade, now is the time to at least have an initial conversation with your CPA.

Does succession planning only matter for large family businesses?

No. The tax exposure is proportional to the business value — but the mistakes we see are just as common in $2M businesses as in $15M ones. The structure of the planning is the same regardless of size.

What’s the biggest tax risk in a family business succession?

Transferring appreciated assets — business equity that has grown significantly over time — without a plan. If ownership transfers at death rather than through a planned transition, the estate may face a bill that forces a sale of the business. Advance planning can dramatically reduce or eliminate that exposure.

Do we need a special attorney for succession planning?

Ideally yes — an estate attorney with business succession experience. But the process should be coordinated with your CPA, not siloed from them. The tax structure and the legal structure need to align. We help facilitate that coordination for our clients in Illinois and Wisconsin.
