What action might be recommended for clients receiving large yearly tax refunds?

The recommended action for clients receiving large yearly tax refunds is to readjust their withholding to improve monthly cash flow. Receiving a large tax refund indicates that clients have been overpaying their taxes throughout the year, which means they are giving the government an interest-free loan with their own money. By adjusting their withholding, clients can have a more accurate amount deducted from their paychecks, resulting in a higher take-home pay each month. This improvement in monthly cash flow enables them to access and utilize their earnings immediately rather than waiting for a refund at tax time.

In contrast, increasing tax deductions or investing the refunds in a retirement account may not immediately address the issue of overwithholding, nor do they directly improve monthly cash flow. Filing for a refund on previous year's taxes is not relevant to managing current financial situations involving withholding adjustments. Thus, readjusting withholding strategically aligns with the goal of optimizing clients' financial situations.
