Different factors can affect the timing of a refund after the IRS receives a return. A manual review may be necessary when a return has errors, is incomplete or is affected by identity theft or fraud.

Other returns can also take longer to process, including when a return needs a correction to Child Tax Credit or Recovery Rebate Credit amount, includes a claim filed for an Earned Income Tax Credit or an Additional Child Tax Credit, or includes a Form 8379, Injured Spouse Allocation , which could take up to 14 weeks to process.
