If you can post your code in a block (or a subset to demonstrate the problem), this might make things clearer. By putting all of your code together, I get the following:

for ( keys %{$payment{$check_number}} ) {
  my $numpayment = scalar ( keys %{$payment{$check_number}{$account}} 
+);
  for ( keys %{$payment{$check_number}{$account} ) { 
    my $last_payment = 0;
    if ( ++$payment_count == $numpayments ) { $last_payment = 1 };
    if ( $last_payment == 1 ) {
      print "last record\n";
      print FH "\n";
    }

I don't think that can be correct as both of your for loops are assinging to $_, thus having your second one trounce on the value of the first. Also, this line is problematic:

  if ( ++$payment_count == $numpayments )

As a general rule, you don't want to autoincrement variables within another expression. You are not guaranteed that it will behave the way you expect. If possible, one way to correct that:

  $payment_count++;
  if ( $payment_count == $numpayments )

It may not effect the program, but it's easier to read. If you can post your code a bit more clearly, we may be able to see the issue (or maybe someone else sees it now, I don't). Since the code above doesn't actually use the $_ variable that you're stepping on, I can only assume that there's more here than meets the monitor.
