Desperate for correct advice

Hello.... My mother is turning 86 in February 2016. She rents out rooms in her house on an informal basis and this provides an irregular income. She has small monthly annuity payment of about R1000 which ceases on her death. What is the taxable income threshold for someone of her age and does she really need to to submit a yearly tax return?
