I have an appt. with a taxpayer later in the week regarding his LLC partnership changing to SMLLC due to his wife passing away. Wife passed away a few years ago but taxpayer's tax preparer continued to file partnership returns and IRS is wanting corrected. I have done a few partnership returns, but am not an expert by any means. My research has found that the partnership needs to liquidate the assets and partnership needs to file a final return. One of my questions is regarding the tax consequences of the liquidation of assets and the step-up value that husband will receive on wife's 50% ownership. Can someone direct me to good info on these issues? Much appreciated.
