my $outfile = $_."_"."$nm" for @lines ;

This line will set/declare $outfile in a loop, which is unlikely to be what you want.

Did you want a loop over @lines instead? Or did you want to take the first element of @lines?

print sprintf "Have %d items\n", 0+@lines;

my $item = $lines[0];
my $outfile = $item . '_' . $nm;
print "$outfile\n";

I tried the following code with the input data in the __DATA__ section for convenience:

#! / usr/bin/perl -w

use strict;
use warnings;

use POSIX 'strftime';

my $nm = strftime('%Y', localtime).".txt";

my @lines = map  { /:([^\s]+)/ ? $1 : () } # take the stuff between th
+e : and the first blank
            grep { /Acct:/ }
            <DATA>; # Read a file line by line and select the lines ma
+tching Acct:

print sprintf "Have %d items\n", 0+@lines;

my $item = $lines[0];
my $outfile = $item . '_' . $nm;
print "$outfile\n";

print $outfile;
#open (OUTFILE, ">$outfile");
# do whatever with the values in @lines
#print "$_\n" for @lines;

__DATA__

foo

Acct:123
Acct:456

Note that you have a close($filename), which likely should be close($fh) in your code.
