Answers to common questions

Why did it take you so long to contact me about this matter?
Our computer systems match the information you report on your tax return with information reported by employers, banks, businesses, and others. This matching takes several months to complete.

I got a deficiency notice. It says I have 90 days to petition the U.S. Tax Court. Does this notice give me more time?
No, you still only have 90 days.

The deficiency notice I got says I have 150 days to petition the U.S. Tax Court. Why doesn't it say 90 days?
You have 150 days for deficiency notices sent outside the U.S. The new notice you just received does not extend the 150 days.

Tips for next year

Consider filing your taxes electronically. Filing online can help you avoid mistakes and find credits and deductions that you may qualify for. In many cases you can file for free. Learn more about e-file.
