You can use the SyntaxForm option of TagBox to resolve this. A common pattern that you'll find with many template styles in Core.nb for situations very much like this (i.e., where the TagBox should simply act as a standalone thing and not as a thing with a given precedence) is using a value of SyntaxForm->=94symbol=94. MakeBoxes[test, form_] := TagBox[RowBox[{"test", "END"}], "myBox", SyntaxForm -> "symbol=94] While the meme of using SyntaxForm->=94symbol=94 isn't documented, SyntaxForm is otherwise documented and I encourage you to look it up.

Thus I cannot simply write "testEND" together as a single string. Also, the parentheses appears in TraditioinalForm, which further appear in all forms as TeXForm, etc. >
