In the desktop version of TaxSlayer Pro, diagnostic errors are displayed on a red background and prevent a return from being electronically filed.
Here is a diagnostic error you will encounter in an unusual return where the tax withheld is greater than the sum of most of the sources of income in the return:
A return containing Tax Withheld greater than the sum of Wages, Interest, Dividends, Total IRA, Total Pension, Unemployment Compensation, Social Security Benefits, Other Income and Gross Receipts from Schedule C is not eligible for electronic filing.
This diagnostic error relates to a IRS Modernized e-File Business Rule F1040-071-07:
Form 1040, 'WithholdingTaxAmt' must be less than the sum of the following: [ 'WagesAmt' and 'TipIncomeAmt' and 'TaxableInterestAmt' and 'OrdinaryDividendsAmt' and ('IRADistributionsAmt' or 'TaxableIRAAmt') and ( 'PensionsAnnuitiesAmt' or 'TotalTaxablePensionsAmt' ) and 'SocSecBnftAmt' and Schedule 1 (Form 1040), ( 'UnemploymentCompAmt' and 'TotalOtherIncomeAmt' ) and ( all Schedule C (Form 1040), 'TotalGrossReceiptsAmt' )] unless one of the following is true: (1) Form 1040, 'CapitalGainLossAmt' has a non-zero value; (2) Schedule 1 (Form 1040), 'OtherGainLossAmt' or 'RentalRealEstateIncomeLossAmt' or 'NetFarmProfitLossAmt' has a non-zero value; (3) Combat Pay has been excluded from wages.
This return will reject if it is electronically filed, thus it needs to be filed in paper form.
