The formulas
- ASC = 14% x (current QREs - 50% x average QREs of the 3 prior years)
- If any of the 3 prior years has no QREs: ASC = 6% x current QREs
- Reduced credit election: credit x (1 - 21%)
How it works
The alternative simplified credit under section 41(c)(4) is 14 percent of qualified research expenses above half of the average QREs of the three preceding years. If the taxpayer has no QREs in any one of those three years, the credit is 6 percent of current QREs.
Without an election, domestic research expenditures are reduced by the credit under section 280C(c)(1). A taxpayer can elect a reduced credit instead, cut by the credit times the highest corporate rate, and the election cannot be revoked. The ASC is an election of the taxpayer. This tool does not compute the regular credit or any credit limits.

Common questions
What are qualified research expenses?
Section 41(b) defines them. Enter the total you determined under that section.
Why is the credit smaller with the election?
You trade a smaller credit for keeping the full deduction, with the credit cut by the 21 percent corporate rate.
Can I get the credit with no QREs in a prior year?
Yes, at 6 percent of current QREs when any one of the three prior years has none.
