Maybe something like this:

        public static MvcHtmlString MyTag(this HtmlHelper helper, string tagName, string innerText, Dictionary<string, string> attributes)
        {
            TagBuilder tag = new TagBuilder(tagName);
            tag.SetInnerText(innerText);
            tag.MergeAttributes<string, string>(attributes);
            return MvcHtmlString.Create(tag.ToString());
        }
    }

and than inside view use it like this:

@Html.MyTag("custom", "Text", attributes)
