rehabilitation may be refunded if the credit exceeds the State
tax liability. A credit may not exceed $3,000,000 for commercial

For Commercial Rehabilitations. If within the rst 5 years

performed that would disqualify a certication or the certied
rehabilitation is disposed of, a portion of the credit is subject
to recapture. A recapture must be made on the tax return for
the tax year in which the disqualifying work or the disposal of
a certied rehabilitation is done.
For Other Rehabilitations. If within the rst 5 years (starting
with the rst year the credit was claimed), work was performed
that would disqualify a certied rehabilitation for which a credit
was claimed, a portion of the credit must be recaptured.
Calculation of the Recapture. The recapture is calculated
• In the rst year, 100% of the credit must be recaptured.
• In the second year, 80% of the credit must be recaptured.
• In the third year, 60% of the credit must be recaptured.
• In the fourth year, 40% of the credit must be recaptured.
• In the fth year, 20% of the credit must be recaptured.
No recapture is required for disqualifying work performed after
the rst 5 years or disposal after the rst 5 years. Line 5 must
be reduced by the amount of the recapture and entered on
