The results found that the profitability and company size had a negative and insignificant effect on the timeliness of financial statements submission. Meanwhile, the capital structure has a positive and insignificant effect on the timeliness of financial statements submission. Simultaneously, profitability, capital structure, and company size do not affect the timeliness of financial statements submission.
