The portion of HPIP tax credits generated in the tax year that are eligible for transfer (50%) may not be carried forward to subsequent tax years for a future transfer. For example, if a calendar year taxpayer with $2,000,000 in HPIP tax credits generated, could transfer up to 50% or $1,000,000 of tax credits. If they only transfer $700,000 to a third party, the remaining $300,000 may not be transferred in any subsequent tax year.
