Folks, we might have a new winner in the contest for the most hated consumer industry. For years, the hands-down winner was car dealers.

But we think that credit card companies are giving them a serious run for their money!

Most credit card companies are downright ingenious when it comes to cooking up sneaky new credit card fees and dirty tricks that take more money out of your pocket. If you've had enough, keep reading because today we are going to reveal seven of the industry's dirtiest tricks. We hope this list will help you protect yourself, slash your costs and be credit card smart.

Dirty Trick #1: Say "Bye-Bye" to Your Grace Period

No grace period means that you'll start accruing interest the moment you charge something. That can cost you a bundle of "extra" interest.

Dear Ken and Daria,

My husband and I are 62. We are debt- and mortgage-free. Our savings, however, are not as high as we'd like. What can we do to make sure we still have money for when we retire in a few years?

Dear Ken and Daria,

I have some credit card debt and have been approached by a debt-reduction company, which says it can reduce my debt 60%-70%. Is this the best way to do it, or should I go to a nonprofit credit counseling firm instead?

Dear Ken and Daria,

Without our knowledge, our 23-year-old daughter ran up $5,000 worth of credit card debt on three different cards. She defaulted and now the collection agencies are coming after my wife and me. We could pay the debt off, but does it make sense to do that?

Ken and Daria Dolan are widely known as America's First Family of Personal Finance.

This time of year, we are all well aware of how much we pay Uncle Sam in income taxes. And we all can clearly see the sales tax we pay when we go shopping or enjoy a nice dinner out. We're not happy about them. But at least we know that we're paying those taxes.

But most of us have no idea just how many hidden taxes we pay every day that take a serious bite out of our wallets. We pay little known-taxes on everything from travel to peanut butter (Ken's favorite), to life insurance to liquor. Often, we don't know, specifically, what federal tax we are paying on goods and services because that tax (such as excise tax on imports or 'sin' taxes on liquor), is built right into the price, and doesn't appear anywhere on the sales slip as a tax.

And boy, does it add up! We consumers pay hundreds of billions of dollars in "hidden" taxes each year. It's estimated that our federal income tax represents less than half of the taxes we pay each year. So let's expose eight hidden taxes you probably didn't even know you were paying...

1. Gasoline tax. Next time you fork over big bucks at the gas pump, remember that you are paying nearly 46 cents per gallon in federal, state and local taxes. That's nearly 15% of the cost of a gallon of gas!

Dear Dolans,

I've followed your advice and actually paid off the balance on one of my credit cards. I'm very excited! Should I cancel that account now?

Maya

Great question, Maya. This is a situation we hear about a lot.

First, let us congratulate you. You've been smart with your money, worked hard and accomplished something significant by paying off one of your credit cards. Well done!

We understand your desire to cancel that account, but that may not be the right thing to do.

There are two very important questions to consider here:

• Is it in your best interest to cancel the card? (It's not always.)
• If you do cancel the account, are you doing it the right way?

Dear Ken and Daria,

I'm about 65 years old and will retire soon. When I do, my company will cancel my life insurance policy. I've been hearing about these burial insurance policies. Should I buy one?

Ken and Daria,

My credit score is 657. My wife and I want to refinance our mortgage, but we need a higher score to get a good interest rate. What can we do to boost our credit score before we talk to our lender?

Here's a little tax trivia for you...

How many pages long is the United States Tax Code? If you guessed 18,500, you win the prize. It's no wonder that so many of us make mistakes when filing our federal income tax forms.

A mistake or two on your tax return can bring you unnecessary stress, delay your refund and subject you to more pesky paperwork -- or worse yet, an appointment with an IRS agent to fix the problem.

But here's the good news... The most common taxpayer mistakes are, for the most part, very simple to avoid once you know to watch out for them. So let's look at the Dolans' Dirty Dozen. Here are 12 common taxpayer mistakes you can easily avoid:
