I have a question about traditional Ira contribution. Since we exceed the income limit, so the contribution of $8000 cannot be used for tax deduction. Then we put it in a traditional Ira account, so is it after tax money? Can after tax money put in a traditional Ira account? Or should we convert it back door to Roth IRA? if so we do not need to pay tax when doing the conversion, correct? or should we just let the money stay in traditional Ira account? What is the benefit of it? Thanks
