具体的退税条文摘抄如下,英语不熟悉的话,找个报税的问问:
Any of these tax credits that are claimed but that are not used in any
taxable year may be
carried forward for five years from the close of the taxable year in which
the vehicles were
purchased or converted. In no event shall the amount of any of these tax
credits exceed
the taxpayer’s income tax liability.
