Can I contributed to my solo 401K if my wife has about 90K/year of salary? If so, what is my maxim contribution?
Adding/Including Spouse in the Solo 401k Plan
“If you file a joint return, you may be able to contribute to an IRA even if you did not have taxable compensation as long as your spouse did. The amount of your combined contributions can’t be more than the taxable compensation reported on your joint return. See the formula in IRS Publication 590-A.”
