When Family Business Meets Estate Planning: Why Your CPA and Attorney Need to TalkJune 10, 2026

Family business estate planning is not estate planning with a business added on top. It is a fundamentally different challenge that requires your CPA and attorney to coordinate at every step – not just hand off documents at the end.

The reason is simple: in a family business, the personal estate and the business are deeply intertwined. Decisions made on the business side (ownership structure, compensation, buy-sell terms) have direct tax consequences on the estate side, and vice versa. When these two tracks are managed independently, the result is almost always conflict, unnecessary tax, or both.

At The Curchin Group, our team has advised family businesses across Monmouth County for decades. The ones that successfully transition between generations are the ones where the business plan and the estate plan were developed together.

The Coordination Problem

Most family business owners have an attorney for estate documents and a CPA for taxes. The problem is that these professionals often work in parallel rather than together.

The attorney drafts a will and trusts based on the owner’s stated wishes. The CPA files tax returns and advises on annual tax strategy. Neither may be fully aware of what the other has recommended, and neither may have seen the business operating agreement, the buy-sell provisions, or the current valuation.

The gaps between these parallel tracks are where the expensive problems live:

• The trust removes business interests from the estate, but the operating agreement does not permit the transfer. Legal conflict delays the succession for months.
• The buy-sell agreement sets a purchase price based on book value, but the estate tax valuation uses fair market value. The IRS assesses the estate at a higher amount than the buyout provides.
• Annual gifts of ownership interest have been made for years, but no formal valuation supports the reported values. The IRS challenges the gift tax returns retroactively.
• The succession plan transfers leadership to one child, but the estate plan divides ownership equally among all children. The child running the business has no control, and the siblings who are not involved demand distributions the business cannot afford.

Every one of these scenarios is preventable when the CPA and attorney plan together from the start.

What Your CPA Brings to the Table

Your attorney handles the legal structure: wills, trusts, powers of attorney, operating agreement amendments. Your CPA brings the financial and tax analysis that determines whether those structures actually work.

Business Valuation

A current, defensible business valuation is the foundation of family business estate planning. It determines gift tax obligations, estate tax exposure, buy-sell pricing, and the financial feasibility of the succession plan.

Valuations are not one-time events. As the business grows, as market conditions change, and as ownership gradually transfers, the valuation needs to be updated. Your CPA ensures the valuation methodology is defensible and consistent with IRS standards.

Tax Modeling

Every succession option has different tax implications. Selling the business, gifting shares over time, transferring to a trust, recapitalizing into voting and non-voting interests – each approach creates a different tax outcome for the owner, the heirs, and the business itself.

Your CPA models these scenarios so you can make informed decisions rather than discovering the tax consequences after the fact. This includes federal estate tax, NJ inheritance tax, capital gains tax, gift tax, and income tax implications for both the business and individual family members.

Succession Timing

Succession planning is not just about who takes over. It is about when and how, with tax efficiency at every stage. Your CPA helps determine:

• The optimal pace for transferring ownership (annual gifting vs. one-time transfer vs. sale)
• When to implement valuation discounts (minority interest, lack of marketability)
• How to structure compensation for the successor during the transition
• When insurance purchases need to be in place
• How to align the succession timeline with the owner’s retirement income needs

Ongoing Compliance

Family business estate planning creates ongoing tax obligations: trust tax returns, gift tax returns, updated valuations, and coordination of individual and business tax filings. Your CPA manages this compliance and flags issues before they become problems.

The Three Conversations That Cannot Wait

If you own a family business and have not addressed these three topics with your CPA and attorney together, you are behind.

1. What Happens If You Die Tomorrow?

Not in five years. Tomorrow. Is the business succession plan funded? Does your family know who takes over operations? Can the estate pay its tax obligations without selling the business? If the answer to any of these is “I am not sure,” the planning is incomplete.

2. What Is the Business Actually Worth?

Not what you think it is worth. Not what a buyer once offered. What would the IRS say it is worth on the date of your death? If you do not have a formal valuation conducted within the past two to three years, you are guessing. Guessing is expensive.

3. Who Gets What, and Can They Afford It?

Equal distribution among children sounds fair, but it rarely works in a family business. The child running the company and the siblings who are not involved have fundamentally different needs. The plan needs to address both fairness and functionality, and the tax treatment of each person’s share needs to be modeled before commitments are made.

Frequently Asked Questions

Why can’t my attorney handle family business estate planning alone?

Attorneys draft the legal documents, but they do not typically model the tax implications of different succession scenarios, prepare business valuations, or manage the ongoing tax compliance that family business transfers create. A CPA provides the financial analysis that determines whether the legal structure achieves your goals.

When should family business succession planning start?

At least five to ten years before the planned transition. Many of the most effective strategies – gradual gifting, trust funding, valuation discount planning – require time to implement. Starting early gives you the most options and the best tax outcomes.

Does every family business need a formal valuation?

If you plan to transfer any ownership interest, whether through gifting, a buy-sell agreement, or estate distribution, a formal valuation is strongly recommended. The IRS requires a defensible valuation to support gift and estate tax returns, and informal estimates do not meet that standard.

Bring Your Advisors Together

The most important step in family business estate planning is getting your CPA, attorney, and financial advisor into the same room. Not sequentially. Together.
