I received a CP14 notice. Where do I send my payment? The address I see is Internal Revenue Service, Austin TX 73301-010. Is this correct?
Most IRS collection centers are not an actual bricks-and-mortar IRS office but rather a P.O. Box without a P.O. Box number shown explicitly. The P.O.Box number is essentially "hidden" in the last 4 (sometimes 5) digits of the nine-digit zipcode. So, to explicitly answer your question "Is this correct?", the answer is is _No since you have shown only 8 of the 9 digits of the Austin TX zipcode. But if you write the zipcode correctly on the envelope in which you mail your check, you should be OK.
See this question and more especially the comments following the answers to the question for a discussion of this point.
