Brett Walters, CFP, financial advisor at TBH Advisors, connects with Financial Advisor Magazine reporter Jeff Stimpson about why wealthy clients should not file their taxes early. “Your financial situation may change and you may wish to delay paying your tax liability until the filing deadline. You may incur penalties and interest on the liability if the payment is delayed, but there may be an opportunity cost to paying early when the funds could have been used for another investment,” said Walters.
