Damone Tyson filed his notice of appeal one day late. Because the government has raised this issue, we must dismiss.

On February 8, 2017, the district court entered a criminal judgment against Da-mone Tyson. Since Tyson was incarcerated, he had until February 22 to mail his notice of appeal to the court. See Fed. R. App. P. 4(b)(1) (criminal defendant must file notice of appeal within fourteen days of the entry of the judgment being appealed), 4(c)(l)-(2) (providing that, where certain requirements are met, inmate’s notice of appeal is deemed filed on date of mailing), 26 (setting out deadline-calculation rules). He did so on February 23. One day late.

Although Rule 4(b) is not jurisdictional, “[w]e are required to dismiss late-filed criminal appeals when the government has raised the issue.” United States v. Dominguez, 513 Fed.Appx. 458, 463 (6th Cir. 2013) (citing United States v. Gaytan-Garza, 652 F.3d 680, 681 (6th Cir. 2011) (per curiam)). Here, the government raised the untimeliness issue, Tyson’s notice of appeal was indeed one day late, and Tyson has offered no response.

This appeal is therefore DISMISSED.
