If you are an owner of the corporation (S-Corp? C-Corp? Something else? It matters) then the corporate return was due March 15, 2019. The penalty for filing late is $200 per member/owner/shareholder per month. So if your corporation has 2 members your late filing penalty is already up to $1600 and it goes up another $400 on Aug 15th. If your state also requires a corporate return and you haven't filed that yet either, then you can most likely double your late filing penalties. So I would highly suggest you seek professional help yesterday, if not sooner.
Be aware also that if you are an owner and/or employee of the corporation, then you can't even start your personal tax return until the corporate return is completed and filed and all W-2's and/or K-1's have been issued to all owners, shareholders and employees.
