<prompt> Human: My wife makes about 500 a week with about 100 of it being a paycheck with taxes taken out. The rest is unreported income.She has filed a tax return the last few years, based on this 100 or so dollars a week.Now that we are married and filing joint-returns, I am afraid to continue this. If i claim the cash as tips or other unreported income would that cause a problem for her employer?If i suddenly claim this income for her would that raise a flag to look at her past income and bank account balancesdeposits?Any help is greatly appreciated. I want to avoid any possible future headaches and problems with the IRS. I have already had to pay back a substantial return I received a few years back after an acquaintance who did my return for me exaggerated quite a bit.  <response>: Who cares if it will cause a problem for her employer? They are just as guilty as she is paying people under the table. My advice would be for her to get a job that doesnt break the law. I want to avoid any possible future headaches and problems with the IRS. Then she should file amended tax returns and pay the tax she owes.
