Answer 1

This will work.
<td><?php echo $row['count(*)']; ?></td>
<td>N<?php echo number_format($row['sum(basic)'],2); ?></td>
<td>N<?php echo number_format($row['sum(hmo)'],2); ?></td>
<td>N<?php echo number_format($row['sum(dha)'],2); ?></td>
<td>N<?php echo number_format($row['sum(tax)'],2); ?></td>
<td>N<?php echo number_format($row['sum(netpay)'],2); ?></td>
<td>><?php echo $row['year(date)'];?> </td>
</tr><?php }?>
Reason: You were tried to pass value in month inside href. And tried to retrieve from get year parameter. Just change from month to year inside href. And you could able to retrieve year now. name parameter must to equal to get name parameter.

Answer 2

This is the URL in your link:
view_payroll_month.php?month=...
The query string parameter is called month. But you try to fetch a value called year:
$_GET['year']
Query string and/or form values are key/value pairs. The values are uniquely identified by the keys (names) with which they're associated. So you need to either:
Fetch the value by month instead of year, or
Pass the value year instead of month, or
Pass the value year in addition to month.
Something like this:
<a href="view_payroll_month.php?month=<?php echo $row['month(date)']; ?>&year=<?php echo $row['year(date)']; ?>">
