SAVAGE, Minn. /ScoopCloud/ -- In 2007, the IRS made the Research & Development (R&D) tax credit a Tier 1 issue, says ICS Tax, LLC (ICS). Tier 1 issues were those of high strategic importance that had a significant impact on one or more industries, essentially meaning that the IRS would audit taxpayers filing amended returns on such issues. To taxpayers' relief, the Tiered Issue Process was eliminated in 2012, effectively placing the R&D tax credit in the same audit pool as other issues.
