To use a life estate value calculator, you need three inputs: a current appraised value for the property, the life tenant’s age at the nearest birthday, and the IRS Section 7520 interest rate for the month of the valuation. Look up the matching decimal in IRS Table S, multiply it by the appraised value, and you have the life tenant’s interest. Subtract from the full value and you have the remainder. The calculation itself takes under a minute; the work is getting the inputs right.
The Three Inputs
Start with fair market value. For federal tax purposes this means a qualified appraisal that follows the Uniform Standards of Professional Appraisal Practice, prepared by a credentialed appraiser who signs a declaration that the report will be used in connection with a tax return.1Internal Revenue Service. Qualified Appraisal and Qualified Appraiser Fees for a single-family home generally run $575 to $1,300. A tax assessment or online estimate will not stand up to scrutiny from the IRS or a Medicaid caseworker, and stale numbers invite pushback, so time the appraisal close to the valuation date.
Next, use the life tenant’s age at the nearest birthday, not the last one. A tenant who turned 74 six months ago is treated as 74; a tenant who turns 75 in two months is treated as 75. The factor shifts every year of age, so an off-by-one error produces an off valuation.2eCFR. 26 CFR 20.2031-7 – Valuation of Annuities, Interests for Life or Term of Years, and Remainder or Reversionary Interests
The third input is the Section 7520 rate. Under Internal Revenue Code Section 7520, valuations of life estates and remainder interests must use a rate equal to 120 percent of the applicable federal midterm rate for the month of the valuation, rounded to the nearest two-tenths of a percent.3Office of the Law Revision Counsel. 26 US Code 7520 – Valuation Tables The IRS posts the current and historical rates on its website. For January 2026 the rate was 4.6%.4Internal Revenue Service. Section 7520 Interest Rates Always pull the rate for the specific month your valuation occurs.
Where to Get Table S
Table S is the IRS actuarial table with single-life factors for life estates and remainder interests. It’s part of IRS Publication 1457 and downloadable as a spreadsheet from the IRS actuarial tables page.5Internal Revenue Service. Actuarial Tables For any valuation date on or after June 1, 2023, use the version built on Table 2010CM mortality data.2eCFR. 26 CFR 20.2031-7 – Valuation of Annuities, Interests for Life or Term of Years, and Remainder or Reversionary Interests An older mortality table produces a valuation the IRS will not accept.
Doing the Calculation
Open Table S, find the column for the Section 7520 rate that applies to your month, and scroll to the row matching the life tenant’s nearest-birthday age. The intersection gives two decimals: a life estate factor and a remainder factor. They always add to 1.00000.6eCFR. 26 CFR 20.2031-7 – Valuation of Annuities, Interests for Life or Term of Years, and Remainder or Reversionary Interests – Section: (d)(2)(iii)
Multiply the appraised value by the life estate factor for the life tenant’s share. Multiply by the remainder factor, or subtract the life estate value from the total, for the remainderman’s share.
Worked example. A home is appraised at $400,000. The life tenant is 72. You pull the 7520 rate for the month, open Table S, and read a life estate factor of 0.42584 at age 72 for that column. The life tenant’s interest is $400,000 × 0.42584 = $170,336. The remainder is $400,000 − $170,336 = $229,664.
Two patterns fall out of the table. A younger life tenant carries a higher life estate factor, because the tables project more years of use. And a higher Section 7520 rate raises the life estate factor, because the present value of the right to use property climbs with interest rates.
Joint Life Estates
Table S is built for one measuring life. When a married couple holds a joint life estate, use Table R(2), which gives two-life remainder factors based on both ages.5Internal Revenue Service. Actuarial Tables The Table R(2) factor accounts for the chance that either spouse dies first and the survivor keeps the life estate. Multiply fair market value by the Table R(2) remainder factor for the remainder interest, then subtract from the total for the combined life estate value. Running Table S on only one spouse’s age would understate the life estate.
Using the Numbers on Form 709
Creating a life estate deed where the owner keeps the life estate and gives the remainder to someone else is a taxable gift. The gift’s value is the remainder interest value from Table S, and it’s reported on IRS Form 709.7Internal Revenue Service. About Form 709, United States Gift (and Generation-Skipping Transfer) Tax Return
Filing Form 709 does not by itself mean gift tax is owed. The reported gift reduces the lifetime basic exclusion, which for 2026 is $15,000,000 per individual after the One, Big, Beautiful Bill raised it from the prior year.8Internal Revenue Service. What’s New – Estate and Gift Tax Filing still matters, because it documents the transfer and establishes the remainderman’s basis.
Using the Numbers for Medicaid Look-Back
The remainder interest value drives the penalty math in Medicaid planning. Federal law sets a 60-month look-back before the date of a Medicaid application for asset transfers made on or after February 8, 2006.9Office of the Law Revision Counsel. 42 US Code 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets If a life estate deed is signed and the applicant files for Medicaid within five years, the state values the remainder interest given away, divides it by the state’s average monthly nursing home cost, and imposes a penalty period during which Medicaid won’t pay.
The divisor varies by state and changes over time, so the same remainder value produces different penalty lengths depending on where and when you apply. The clock runs from the transfer date, not the application date. If Medicaid coverage is the goal, the deed needs to be executed at least five full years before any anticipated application.
What the Numbers Mean at Sale or Death
If the property is sold while the life tenant is alive, the proceeds are split between the life tenant and remainderman using the factors at the time of closing. The title company or escrow officer usually handles the split from an updated worksheet, and each party reports their own share of the gain.
The life tenant may qualify for the Section 121 capital gains exclusion on their share if the home was their principal residence for at least two of the five years before sale. That exclusion covers up to $250,000 in gain for an individual or $500,000 for a married couple filing jointly.10Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence The remainderman usually owes capital gains tax on their proportionate share unless they independently meet the ownership and residency requirements.
Section 121 also lets a taxpayer elect the exclusion on the sale of a remainder interest in a principal residence, but the election does not apply to sales between related parties.10Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence A child selling their remainder back to a parent or sibling can’t use the exclusion.
If the property is held until the life tenant dies, the tax picture is different. Section 2036 pulls the full property value back into the life tenant’s gross estate at death.11Office of the Law Revision Counsel. 26 USC 2036 – Transfers With Retained Life Estate That inclusion triggers a stepped-up basis: the remainderman takes the property with a basis equal to its fair market value on the date of death.12Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent
A parent who bought a house for $100,000, deeded the remainder to a child, and dies when the house is worth $500,000 leaves the child with a $500,000 basis. A sale the next day at $500,000 produces zero gain. A lifetime gift of the same property, by contrast, carries over the $100,000 basis and leaves the child with a $400,000 taxable gain on sale.
Keep the Paper Trail
Save the appraisal, the Table S factors used, the Section 7520 rate for the valuation month, the completed worksheet, and any Form 709 filing for at least seven years. Both the life tenant and the remainderman should have independent copies. Disputes over life estate valuations rarely turn on the arithmetic; they turn on nobody being able to reconstruct which inputs were used.
