Estimated Tax & Extension of Time to File
- Do you owe estimated tax?
- Find alternative payment methods - pay online or fill out Form ES-40.
- Figure penalty (or exemption to penalty) if estimated tax was owed but not properly paid.
You may owe a penalty if:
- You didn't pay any estimated tax,
- You didn't pay enough estimated tax, or
- You didn't make your payments on time.
You may not owe a penalty if you meet an 'exception' to the penalty.
