This paper aims to present the effect of life-cycle on financial reporting quality (FRQ). I used Discretionary accruals, small profit, and audit aggressiveness to test the FRQ from different approaches for Borsa Istanbul-listed companies between 2008 and 2017. The sample comprises 1,645 observations, 217 companies, and nine years. I estimated the life stages with Dickinson’s (2011) cash flow patterns. Following Hansen et al. (2018), I assigned values of 0, 0.25, 0.5, 0.75, and 1 for introduction, growth, mature, shake-out, and decline, respectively. The findings for small profit and discretionary accruals are consistent with conjecture. Discretionary accruals and small profit decrease as the companies move forward in their life-cycles. On the other hand, audit aggressiveness increases when the firms grow further in their life-cycles. I observed a negative coefficient, but it was insignificant for the other dependent variables. The findings provide an insight into the effect of life-cycle stages on FRQ. My results showed that the introduction and decline stages negatively affect FRQ. My results also showed that audit aggressiveness of Turkish companies decreases with increased listing duration.
