Any errors or inconsistencies in filing or paying payroll taxes may cause your business to be audited. Failing to file payroll taxes, inconsistently filing, or paying late, deducting the wrong amount from employee paychecks, and even making math errors in returns may flag a payroll tax audit. Sometimes, according to the IRS, a business return may be selected for audit if the taxes of a business partner with whom you had transactions are being audited. And in some cases, business returns are randomly selected for audit based on a statistical IRS formula. If you have received an audit notice from the IRS, reach out to a payroll tax lawyer who will represent your interests during the audit process.
