I have been a loyal customer of Tax Slayer for 4 years, but I will never use again. They incorrectly added me and my spouses Social Security and caused us a penalty of $1,790.19... When questioned, the person on the phone had me on hold for ~30 minutes and then told me to call the IRS. She said there was no line 72 on tax form 1040... which is clearly false.
Be smart - DO NOT USE TAX SLAYER
