What time of year are people most likely to deposit funds into their savings accounts?

Behavorial Economics
A report by Common Cents Lab, associated with Duke University, found that the period each year where Americans are most likely to be open to saving money, talking about savings or setting up plans to save is during tax season. With an average tax refund about $3,000 per family, tax season can be one of the few times each year when a family can save money, pay down debts and think clearly about their financial stability and future planning.
How much they save depends on when they are asked.
Common Cents used a control group of users right after a tax refund appeared in their bank accounts and asked what percentage of the refund the user would like to save. The average answer was 10%. The experimental group was texted before a refund arrived and asked the same question. Their average answer was 15%.
