When a taxpayer signs a tax return they sign under an statement (jurat) that says:
"Under penalties of perjury, I declare that I have examined this return and accompanying schedules and statements, and to the best of my knowledge and belief, they are true, correct, and complete. Declaration of preparer (other than taxpayer) is based on all information of which preparer has any knowledge."
Taxpayer is an employee of a C Corp. Taxpayer is also a 50% shareholder in that C corp and signs on the bank account and signs payroll tax returns.
Taxpayer knows that payroll taxes are not being paid. Taxpayer has a W-2 that shows withholding. When taxpayer files the return it will show an overpayment and generate a refund.
Can taxpayer sign the return pursuant to the jurat above?
