Disputing our assessment of your claim
If you dispute our assessment of your R&D tax credit, you can request a reassessment of your claim by submitting a notice of proposed assessment (NOPA).
In some circumstances, different timeframes apply for submitting a NOPA or a detailed statement in support of a NOPA.
When the disputes process is complete, you cannot submit a NOPA for an R&D tax credit for the disputed period that has been resolved. However, we still have discretion to amend the claim.
Refer to our standard practice statements for more information about your rights and responsibilities:
