I'm a little confused by your question, but I think you're asking whether the IRS updates your mailing address, in its own databases, based upon the address you used on your last tax return. That answer is yes. By law the IRS is required to mail notices to your "last known address." The address that you used on your last tax return is the most common way of setting the "last known address."Ask a similar question
go to irs.gov request the address change form and file it yourself by certified mail. Always best to have the IRS have the most current address.

You incorporated with the Department of State with an address to have service of process on the corporation (assuming NY corp.). When you requested an EIN you had to insert an address on the form SS-4. If your tax return you filed recently has a different address then those address' then you should file with the IRS a change of address form.Ask a similar question
