Don't forget there are loads of dues you can claim as miscellaneous expense deductions. Some are more obvious than others; union dues, for instance, should absolutely be deducted. (And don't forget to include initiation fees.)
But it doesn't stop there. If you belong to professional, civic or public service organizations, you can deduct your fees as well. Lawyers can deduct their bar fees and doctors their medical association dues, for instance. But quite a few other organizations also fall under the umbrella of dues you can deduct. If you belong to trade organizations -- or any professional group that helps you carry out your job -- you can feel comfortable deducting fees.
Now don't think you can join the country club and call it business dues. The IRS does know the difference between social or entertainment clubs and professional ones. You're not going to find Uncle Sam paying to help improve that chip shot.
