<div style="float:left; width:100pt">
        <h2>                                           
        :<xsl:value-of select="format-number(cbc:TaxAmount,'#,##0.00', 'us')"/>
        </h2>
</div>

Answer 1

You can use abs() function

<xsl:value-of select="format-number(abs(cbc:TaxAmount),'#,##0.00', 'us')"/>

You can use if statement

<xsl:choose>
     <xsl:when test="cbc:TaxAmount < 0">
       <xsl:value-of select="format-number(cbc:TaxAmount * -1,'#,##0.00', 'us')"/>
     </xsl:when>
     <xsl:otherwise>
      <xsl:value-of select="format-number(cbc:TaxAmount,'#,##0.00', 'us')"/>
     </xsl:otherwise>
   </xsl:choose>
