According to a QuickBooks Payroll survey, 6 in 10 business owners prefer to leave payroll to the pros. Business owners who don’t outsource spend 4 hours and 52 minutes each pay period calculating, filing and paying payroll taxes (a total of 21 days a year). Getting it wrong can trigger IRS problems, with 40% of businesses with more than 10 employees saying they were audited or fined with respect to payroll taxes.
