A typical estate plan assumes assets that can be valued, divided and sold. An owner’s largest asset is often none of those.
It may be worth more with them than without them. It can’t be split evenly among children who may or may not work in it. And New York’s estate tax may be due in cash nine months after death. Owners need an estate plan built around the business, and a different one after it’s sold.
What’s different for owners
Value is uncertain
A private company needs a formal valuation, and the number can be challenged.
It’s hard to divide
One child runs the company, another doesn’t. Equal isn’t always fair.
Taxes need cash
An estate tax bill can come due before the business can be sold sensibly.
Control matters
Who votes the shares and runs the company if you can’t is as important as who inherits them.
New York’s numbers are the ones that bite
With a $15 million federal exclusion per person, most owners won’t owe federal estate tax.
New York is different. Its 2026 exclusion is $7.35 million, there’s no portability between spouses, and once a taxable estate passes 105% of the exclusion, the entire estate is taxed. A business worth $6 million plus a home and retirement accounts can put an owner over the cliff without anyone noticing.

Before a sale: the best window
- Gift shares to children or trusts while the company is valued as a private, hard-to-sell business. Once a buyer offers a price, values tend to follow it.
- Minority, non-voting interests may qualify for valuation discounts, supported by a qualified appraisal.
- New York has no gift tax, but gifts made within three years of death are added back to the estate.
- Gifting the business before a sale moves future growth, and the sale proceeds, out of your estate.
- Keep enough for yourself. Gifts are permanent, and you’ll need to live on what you keep.
The buy-sell agreement
If you have partners, the buy-sell agreement may be the most important estate document you own. It decides who can buy your shares at death, disability or departure, at what price and how it’s funded.
An outdated price or an unfunded promise can leave your family selling to your partners for far less than the business is worth, or receiving an IOU.
After a sale: a different plan
| Before the sale | After the sale | |
|---|---|---|
| Main asset | The business | Cash and investments |
| Valuation | Uncertain, discounts possible | Exact, no discounts |
| New York cliff | Maybe | Often |
| Liquidity for taxes | A problem | Solved |
| Key decisions | Gifting shares, buy-sell, succession | Gifting cash, trusts, charitable plans, the cliff |

Questions owners ask
Does New York have a gift tax?
No. But taxable gifts made within three years of death are added back into the New York estate.
When should I gift shares of my business?
Usually well before a sale is negotiated, when the company is valued as a private business. Gifts after a buyer’s offer tend to be valued near the offer.
What is the New York estate tax cliff?
If a taxable estate exceeds 105% of the exclusion, $7,717,500 in 2026, the whole estate is taxed, not just the excess.
Do I need a buy-sell agreement?
If you have co-owners, yes. It sets the price and process if an owner dies, becomes disabled or leaves, and how the purchase is paid for.
Where this guidance stops
This article is general education on estate planning for business owners: how the rules and the options generally work.
It is not tax, legal or investment advice, and nothing here is a recommendation for your situation. Rules change and outcomes turn on the facts, which is why a CPA and an attorney look at a family’s own numbers before anything is done.
