Client just received a $3,000.00 even refund check from IRS... It appears that it is in error... Client, MFJ no kids, standard deduction, NO RRC, NO EIC, NO Health insurance penalty, NO unemployment comp., owed money on the return and paid it... No letter was received yet to explain the $3,000.00 check... I analyzed the return and the estimates paid and the economic impact payments and so forth and I cannot figure out why they received this check... I advised client not to cash the check and to wait for the letter from IRS to explain refund check.... Has anyone else experienced this or have a possible explanation... Thanks in advance for your help...
