Edition 37 of selfmanagedsuper examines an issue that has implications for every single SMSF trustee – Director Identification Numbers – and what needs to be done to comply with this new regime. Our regular contributors consider the value of alternative assets in an investment portfolio, and optimising tax outcomes for an SMSF. The details of different property purchases are also examined, as is the best way to use a withdrawal and recontribution strategy while end of life considerations are covered in two articles covering winding-up a fund and estate planning within an SMSF.
