The Occupancy Fork: South Carolina Taxes an Inherited Home at 4 Percent if You Move In, 6 Percent if You Do Not

Updated August 2026

South Carolina sorts every home into one of two columns, and the sorting question is not who owns it but who sleeps in it. A legal residence is assessed at 4 percent of fair market value under S.C. Code 12-43-220(c). Every other piece of real property sits in the 6 percent column under 12-43-220(e). No other state draws this line as sharply, and nowhere does it bite harder than at an inheritance, because the column is not part of the estate. The decedent's 4 percent classification ends with the decedent. Which column the house lands in next depends entirely on what the heir does.

The 4-versus-6 arithmetic also understates the real gap. Under S.C. Code 12-37-220(B)(47), a home receiving the 4 percent ratio is exempt from all property taxes imposed for school operating purposes, though not from millage repaying general obligation debt. School operating millage is typically one of the largest lines on a South Carolina tax bill, and it comes roaring back the moment a home falls into the 6 percent column. This guide walks through both forks an heir faces, the occupancy fork that sets the ratio, and the ATI fork that decides whether the appraised value resets, then covers the 25 percent discount for landlord heirs, the homestead exemption rules, and the appeal clock.

Two Columns, One Question

To hold the 4 percent ratio, the owner must hold title in fee or by life estate, occupy the home as a legal residence, and be domiciled there. The classification covers the house and up to five contiguous acres. Everything that fails that test, second homes, rentals, the vacant house an out-of-state heir is still deciding what to do with, is assessed at 6 percent.

Heirs routinely assume the house keeps its old classification because nothing about the property changed. The statute says otherwise. Under 12-43-220(c)(2)(vi), when ownership changes, a new application is required from the new owner to qualify the residence for future years. Until an heir who actually lives there files that application and proves domicile, the default column for an inherited house is 6 percent.

What the 6 Percent Column Actually Costs

Moving from 4 percent to 6 percent raises the assessed value by half. Losing the school operating exemption then applies a larger millage rate to that larger base. The two effects multiply. Here is a worked example with round, hypothetical numbers, since millage varies by county and district:

• The house: appraised at $300,000, in a district levying a hypothetical 300 mills total, of which 120 mills fund school operations.
• Occupying heir at 4 percent: assessed value $12,000, school operating millage exempt, so tax applies at 180 mills. Bill: about $2,160.
• Absentee heir at 6 percent: assessed value $18,000, all 300 mills apply. Bill: about $5,400.

Same house, same year, same market value. The absentee heir pays roughly two and a half times what the occupying heir pays in this scenario. That multiple is why the occupancy fork, not the appraisal, is usually the biggest single tax decision an heir makes in South Carolina.

The Second Fork: Does Death Reset the Appraised Value?

Separate from the ratio, South Carolina asks whether the transfer was an assessable transfer of interest, or ATI, under Act 388. When an ATI occurs, S.C. Code 12-37-3140 sets the property's fair market value fresh as of December 31 of the transfer year, and the new value is first taxed the following year. Between ATIs, owners enjoy real protection: increases from the countywide reassessments that run on five-year cycles are capped at 15 percent. An ATI value ignores that cap entirely. A house last appraised years ago can jump the full distance to market in one step.

Inheritance transfers the statute leaves alone

S.C. Code 12-37-3150(A)(6) makes a distribution under a will or by intestate succession an ATI, and then carves out two families of exceptions that cover a surprising share of real inheritances:

• The surviving spouse. A distribution to the decedent's spouse is not an ATI. The appraised value carries over untouched.
• Children of a parent who had no spouse. If the decedent had no spouse at death and the home carried the 4 percent legal residence ratio, a distribution to the decedent's child or children is not an ATI either. This is the classic second death in a family: the widowed parent passes the family home to the kids, and the appraisal does not reset. The statute adds one warning, though. When those children later convey the property, that sale is not exempt.
• Certain trust distributions. A distribution from a trust is not an ATI when the distributee is the sole present beneficiary or that beneficiary's spouse, under 12-37-3150(A)(4).
• Retained life estates. Where the decedent deeded the home away but kept a life estate, 12-37-3150(B)(2) delays the ATI until the life estate ends. Practically, the reset arrives at the life tenant's death.

Inheritance transfers that do trigger the reset

Outside those carve-outs, the ATI rules apply with full force. A home passing to siblings, grandchildren, nieces, or friends is an ATI. So is a home passing to the decedent's children when the decedent left a surviving spouse, or when the property was not the decedent's 4 percent legal residence, which means the family beach rental at 6 percent resets even when it goes straight to the kids.

Keep the two forks straight, because they move independently. A child who escapes the ATI still pays the 6 percent ratio if they never move in. An heir who triggers the ATI can still claim 4 percent by making the house home. One fork sets the value, the other sets the ratio, and the bill is the product of both.

Claiming the 4 Percent Column as the New Owner

An heir who occupies the inherited house applies with the county assessor, not the state, and must do so before the first penalty date for taxes of the first year claimed. The application is a sworn certification of domicile, and the burden of proof sits with the owner-occupant. Assessors can require a copy of your South Carolina income tax return and motor vehicle registrations showing the property's address. A household may claim only one 4 percent residence, and the home cannot be rented for more than 72 days in a calendar year without losing the classification. If the assessor denies the application, the 6 percent ratio applies and the classification itself can be appealed through Chapter 60, the same track as a value appeal.

One recovery tool worth knowing: under S.C. Code 12-37-252(C), if the person you inherited from qualified for the 4 percent ratio or the homestead exemption but never filed the paperwork, the estate's personal representative is deemed the decedent's agent and can file those applications, and claim the resulting refunds, for the years that were still open at death. Estates of elderly owners who quietly overpaid for years should check this before closing.

Keeping It as a Rental: The 25 Percent ATI Exemption

Landlord heirs get one meaningful discount. Under S.C. Code 12-37-3135, when property subject to the 6 percent ratio undergoes an ATI, the owner may claim an exemption equal to 25 percent of the ATI fair market value. There is a floor: the exemption cannot push the taxable value below the current fair market value already on the assessor's books. In other words, it softens the jump from the old book value to the new appraisal, but never cuts below where the value already stood.

The claim is not automatic. The owner or the owner's agent must notify the county assessor that the property will be subject to the 6 percent ratio before January 31 of the first tax year the exemption is claimed. Miss the notice and the full ATI value applies. File it once and no further notice is needed while the property stays at 6 percent.

The $50,000 Homestead Exemption Belongs to a Person, Not the House

Separate from the 4 percent ratio, S.C. Code 12-37-250 exempts the first $50,000 of fair market value from county, municipal, school, and special assessment taxes for an owner who has been a South Carolina resident for at least one year and is 65 or older, totally and permanently disabled, or legally blind. Application goes to the county auditor, generally before July 16 of the tax year. Heirs do not inherit this exemption; a 45-year-old heir moving into a late parent's home can claim the 4 percent ratio but not the senior homestead.

The one continuation the statute allows is for a surviving spouse. If the deceased owner qualified, or would have qualified at death, the exemption continues for the spouse who acquires fee simple title or a life estate to the home within nine months of the death, remains unmarried, and keeps the home as their legal residence. A qualifying surviving spouse who sells and buys another South Carolina home can even carry the exemption to the new dwelling.

No Death Taxes, and a 90 Day Clock if the Number Is Wrong

South Carolina imposes no inheritance tax on heirs, and the Department of Revenue confirms the state has had no estate tax for decedents dying on or after January 1, 2005. Only the federal estate tax can reach a South Carolina estate, and only above the federal exemption, which the overwhelming majority of estates never approach. The recurring cost of inheriting here is the property tax structure described above, not a transfer tax at death.

If the county's number is wrong, the remedy is a written objection to the county assessor within 90 days after the assessment notice is mailed, under S.C. Code 12-60-2510(A)(3). A written request to meet with the assessor counts as the objection, and if the conference does not resolve it, you have 30 days after the conference to file a formal written protest. ATI reassessments are bulk appraisals of a home the assessor has usually never entered, and estate properties often carry deferred maintenance and dated records that mass appraisal misses, so the reset value deserves scrutiny, not deference.

One quirk that favors heirs: South Carolina assessors only mail assessment notices when a value rises by $1,000 or more, so in most years no notice comes at all. Under 12-60-2510(A)(4), in a year with no notice you may appeal in writing at any time, and an appeal filed before the first penalty date counts for the current tax year.
