The CP16 means the IRS corrected one or more errors on your return, and the corrections changed your refund amount. This is similar to the CP12 but may involve different types of corrections. The notice shows what was changed and your adjusted refund.
Types of Corrections
The CP16 can reflect math errors, mismatched entries between schedules and the main return, incorrectly transferred amounts from supporting forms, duplicate entries, and other processing corrections. The IRS uses its math error authority to make these changes without a full audit.
Your 60-Day Rights
Like other math error corrections, you have 60 days to request abatement. If you dispute the corrections within 60 days, the IRS must reverse them and follow normal deficiency procedures. After 60 days, the corrections become final.
Review Carefully
Compare every correction to your original return. The IRS usually gets math corrections right, but errors in their processing do occur. Common IRS mistakes include not properly crediting estimated tax payments, misreading amounts from paper returns, and incorrectly adjusting entries that were actually correct.
If your refund was reduced and the corrections are wrong, respond within 60 days with documentation. If the corrections are right, your adjusted refund will be processed automatically.
