I have a client who cannot make Roth contributions due to income. He makes an annual nondeductible contribution and the following tax year we make a Roth conversion on his account. The fund company used has told me it is not necessary to wait until the following year and that they can accept his nondeductible contribution and convert it to his Roth account on the same day. Is this correct? I have been under the belief that there needed to be a longer timeframe before conversion.
