We are using “Sponge Document Template” for customer invoice. It will be good not to print Tax information and remaining unpaid if the values are Zero. It will save space of the Invoice. please find attached image

Would be great if the following logic implemented in the Invoice printing (Tax details)…  
If Tax-2 & Tax-3 used then no need to print Tax-1  
Since In India either Tax-1 used OR Tax-2 & Tax-3 used.for both Sales and Purchase (All 3 tax are not used anywhere).  
Also if Remaining unpaid=0 then need not to print this line (to save the space)  
thank you

Inside the class pdf\_sponge , locate the method drawTotalTable and find the section that displays the VAT breakdown.

```auto
if (!getDolGlobalInt('PDF_INVOICE_SHOW_VAT_ANALYSIS')) {
    // VAT
    foreach ($this->tva_array as $tvakey => $tvaval) {
        if ($tvakey != 0 || getDolGlobalString('INVOICE_SHOW_ALSO_VAT_LINE_IF_ZERO')) {
            // ... output the line
        }
    }
}

```

Replace the `if` condition with one that also checks that the tax amount is not zero:

```auto
if (($tvakey != 0 || getDolGlobalString('INVOICE_SHOW_ALSO_VAT_LINE_IF_ZERO')) && $tvaval['amount'] != 0) {

```
