What Is a Step-Up in Basis Appraisal—and When Do You Need One?

If you inherited a farm, ranch, home, or other real estate after someone passed away, you may hear your accountant or attorney say:

“We need a date-of-death appraisal for the step-up in basis.”

That sounds complicated. The basic idea is actually pretty simple.

What Is a Step-Up in Basis?

Think of basis as the starting value used when figuring taxes if a property is later sold. Let's use a simple example.

Grandpa bought the farm for $100,000. When he passed away, it was worth $500,000.

Think of that $500,000 as your new starting point.

If you later sell the farm for $550,000, it has gained $50,000 in value since you inherited it. That $50,000 is the gain your CPA may use when figuring your capital gains tax—not the entire $550,000 sale price.

In simple terms, the date of death can act like the start of the clock for you.

Your CPA or tax professional will determine the actual taxable gain and how the tax rules apply to your situation.

What Is a Date-of-Death Appraisal?

A date-of-death appraisal answers one main question:

What was this property worth on the date the owner passed away?

If the date of death was June 1, 2026, the appraisal looks at the property and market as of that June 1, 2026 date.

The appraisal may be completed weeks, months, or even years later. The important part is that the appraiser is developing an opinion of value as of that past date.

This is called a retrospective appraisal.

Why Is It Better to Get the Appraisal Done Early?

If you know you need a step-up in basis appraisal, getting it completed sooner is usually easier.

When only a few weeks or months have passed, the property often hasn't changed much. The appraiser can see the property close to the date being valued, making it easier to know what was there and what condition it was in.

The market information is also fresh. Comparable sales, leases, photographs, property records, and other information from around the date of death are generally easier to find.

There is another practical benefit. If the family plans to sell the property soon after the date of death, the appraisal can also help determine a reasonable asking price. In a stabilized market, where property values have not changed significantly, a recent date-of-death appraisal may still provide a good starting point for the sale price.

A new appraisal may still be needed for a lender, court, or another purpose, but getting the date-of-death appraisal done early gives you the information you need while everything is still fresh.

One Less Thing to Worry About

I understand that this can be a hard and emotional time. My goal is to make the appraisal one of the easiest things on your list.

I try to gather as much information as possible during our first phone call, email, or text so I don't have to keep coming back to you with questions.

Once I have what I need, let me take it from there. I'll research the property, gather the information, and complete the appraisal so you have it when you need it.

What If the Date of Death Was Years Ago?

Don't assume it's too late. An appraiser can complete a retrospective appraisal years after the date of death.

For example, suppose a parent passed away in 2018 and the family kept the farm. Now it's 2026, and the family decides to sell.

An appraiser can go back and research the 2018 market to determine what the farm was worth at that time.

If it was worth $400,000 in 2018 and sells for $650,000 in 2026, that $400,000 value may become an important starting point when your CPA figures the gain.

Going back several years can take a little more research. Buildings may have been added or removed, the house may have been remodeled, or the land itself may have changed. The appraiser's job is to figure out what the property looked like and what it was worth on the date of death—not what it is worth today.

That may mean using old aerial photos, property records, maps, previous listings, family photos, and historical sales.

It may be easier to get the appraisal done early, but harder does not mean impossible. Even if the date of death was years ago, talk with your CPA or attorney before assuming you've missed your chance.

What Should You Have Ready for the Appraiser?

Don't worry if you don't have everything. The appraiser can help determine what information is needed.

With today's technology, we can go back and find a surprising amount of historical information. We can pull old aerial photos, soil maps, topography maps, property records, and other information from years ago to help understand what the property looked like at the time.

Honestly, it's kind of cool how much information we can find!

The Bottom Line

A step-up basis appraisal doesn't have to be complicated.

Someone passed away. You need to know what the property was worth at that time. The appraiser's job is to help answer that question.

Your CPA or attorney determines how that value should be used for tax or estate purposes.

For families who own farms, ranches, rural homes, and other agricultural property, having a well-supported date-of-death value can provide an important piece of information—whether the loss occurred a few months ago or many years ago.
