How to Calculate the Arizona R&D Tax Credit

Arizona offers two methods: regular (incremental) and Alternative Simplified Credit (ASC). Both use Arizona-sourced QREs only.

Regular Method
  • Determine total Arizona QREs for the tax year.
  • Compute base amount = fixed-base percentage × average Arizona gross receipts for prior 4 years (minimum 50% of current QREs).
  • Calculate excess QREs = current QREs - base amount.
  • Apply tiered credit: 24% on excess ≤$2.5M; 15% on excess >$2.5M (until 2030).
Example Calculation
QREs = $3M;
Base = $500K;
Excess = $2.5M
→ Credit = (24% × $2.5M) + (15% × $0) = $600K
If excess = $4M:
→ (24% × $2.5M) + (15% × $1.5M) = $600K + $225K
= $825K
Alternative Simplified Credit (ASC)

Simplifies base to 50% of average QREs over prior 3 years (or 0% if no prior QREs). Credit = tiered percentage of excess (same as regular).

Calculation Steps:

1.Calculate average Arizona QREs from prior 3 years
2.Base = 50% of that average (or 0% if no prior QREs)
3.Excess = Current year QREs - Base
4.Apply tiered rates: 24% on first $2.5M excess, 15% above

Important: Election is irrevocable without approval.

Gross Receipts for Base Calculation
  • Use Arizona-sourced gross receipts only (exclude returns, allowances).
  • Startups: Fixed-base starts at 3% for first 5 years, phases to 16% by year 10.
  • No Arizona gross receipts? Base defaults to 50% of current QREs.
