For my Tax Refund I received in 2019. I invested my $1000 right away into my Roth IRA. I purchased over 35 shares of $EADSY (Airbus SE) as a long-term investment in the aviation industry and will continue to purchase additional shares into 2019.
Most people who receive their tax refunds will spurge into unnecessary purchases into materialistic items or vacations they cannot afford and become broke. The smart ones will invest their money into their Roth IRA, save it in a emergency fund, or start a business to grow their money.
In the end it is up to you on what you want to do with your Tax refund but you must have the financial discipline to save and invest, then spurge later on without having to worry about money.
