INSTRUCTIONS
Taxpayers can take the Certified Historic Structure Credit against their Income Tax or Corporate License Fee. The credit
is for qualified rehabilitation expenditures to a certified historic structure, as defined in IRC Section 47 and applicable
Internal Revenue Service regulations. To be eligible, a rehabilitation project must meet all requirements for the federal
20% Income Tax credit under IRC Section 47.
Additional work done within five years must be consistent with the Secretary of the Interior's Standards for Rehabilitation.
The State Historic Preservation Officer may review and inspect the additional work. If the State Historic Preservation
Officer determines the additional work is inconsistent with the Standards for Rehabilitation, you will forfeit any unused
credit. If you disagree with the determination, you can request a review by filing an appeal with the State Review Board.
Complete a separate TC-21 for each rehabilitated property. To claim a credit for rehabilitation expenses for a certified
historic residential structure, complete the TC-22.
Line instructions
Line 1: Enter the amount of qualifying rehabilitation expenses made to a certified historic structure located in South
Carolina and placed in service during this tax year.
For projects with rehabilitation expenses of $500,000 or greater, a taxpayer claiming a credit must pay a preliminary fee
and final fee to the SCDAH. The fee schedule is located in SC Code Section 12-6-3535, available at dor.sc.gov/policy.
When filing the TC-21, include a copy of the documentation from the SCDAH confirming that you have paid the fees.
Line 2: The South Carolina credit amount is 10% of the amount qualifying under IRC Section 47. You may elect a 25%
tax credit instead of the 10% credit, not to exceed $1 million for each certified historic structure.
Line 3: The credit is claimed in equal installments over a three-year period beginning with the tax year the property is
placed in service. To calculate the installment amount in the year the property is placed in service, divide line 2 by 3. If the
property was placed in service in a prior year, enter the amount from line 3 of last year's TC-21.
