10 Really Surprising Things That Can Hurt Your Credit Score

10 Really Surprising Things That Can Hurt Your Credit Score

Most people know the typical credit no-nos:

Don’t make a late payment. Don’t allow an account to go into collections. Avoid tax liens, bankruptcies and foreclosures.

And of course, paying off credit card debt should be one of your top financial priorities.

But there are also lesser-known ways you could unintentionally damage your credit score.

Here are ten actions—from least to most harmful—that could make your number take a plunge.

10. Renting a Car With a Debit Card

While many rental agencies require that you pay your deposit with a credit card, some will accept your debit card instead. However, agencies typically have a clause in the contract stating that they can pull your credit report if you choose to pay with a debit card. That credit check causes a hard inquiry, which can ding your score a few points.

A hard inquiry is when a lender, credit card issuer or other financial institution requests a credit check in order to decide whether or not to extend a line of credit to you, such as a credit card or home loan. Each hard inquiry usually drops your credit score by a few points and will remain on your credit report for two years. The other kind of inquiry, soft inquiries, are made by people who don't intend to take action, such as your landlord checking your credit, and won't have any effect on your credit score.

9. Requesting a Credit Limit Increase

While it could be a good idea to ask for a limit increase on your credit card (and might help your credit score in the long run), it could also damage your score in the short-term if it initiates a hard credit inquiry. When calling to request a limit increase, make sure to ask first if it will initiate a hard or soft inquiry on your credit report. Each institution handles it differently.

8. Applying for an Account at a Credit Union

With lots of people moving their money from big banks to smaller credit unions, it’s important to know that opening that new account could cause a hard inquiry. Before applying, ask whether or not opening a new account will involve a hard inquiry into your credit report. The inquiry isn't unique to credit unions—most institutions conduct a hard inquiry when you open a new account.

7. Getting a New Cell Phone

Opening a new mobile account could also initiate a hard credit inquiry. Although each hard inquiry shouldn't drop your score too drastically, you'll want to be careful not to initiate too many in too short a time, or else these little actions can really add up.

6. Using a Business Credit Card

It used to be that business credit card activities didn’t show up on your credit report, but that’s no longer true. These days, all major credit card issuers require that you provide a “personal guarantee” when applying for a business credit card. That means you’ll essentially be a co-signer with your company on the card. Your company may be responsible for paying the balance, but your credit will take a hit if you fail to keep up with the paperwork or they default on a payment. If you work for a small, young business and need a business card for work expenses, first ask if you'll have to provide a personal guarantee. If the answer is yes, you may instead want to use your own credit for business expenses and fill out expense forms.

5. Not Using Your Credit Cards

If you have a credit card account in good standing that has zero activity over a long period of time, your credit card issuer could choose to close your account due to inactivity. If you’re not using it, you may not notice that your account has been closed until your credit takes a hit. The reason this would hurt your score is that it would be bad for your credit utilization ratio. For more on what that is and why it matters, check this out.

4. Disputing a Credit Card Bill

If you’re in the midst of a credit dispute, some credit score algorithms may not take the disputed credit line into account when calculating your score, so a credit check done on your profile during that time could cause your score to be lower than it would be if the disputed account were included. Why? Again, by lowering your total "available" credit line, your credit utilization ratio would change, and not for the better.

3. Using a Finance Plan for a Major Purchase

A small, local furniture retailer may offer to let you finance a purchase ... but if you accept the loan, it can hurt your credit because it’s considered a “last-resort” loan, which may make you look like a higher credit risk. Additionally, your credit could suffer from the high balance being reported on your credit.

For instance, say you apply for credit to finance a $1,400 couch. You get a great offer: no payments and 0% interest for 18 months. You take a few months to start making payments, and in the interim you have a new line of credit on your credit report. The new line will essentially be maxed out, because the limit will be $1,400 and your balance will be $1,400. Your credit utilization rate, therefore, would be negatively affected.

2. Closing an Old Credit Card Account

It may seem like a good idea to get rid of an old credit card, but it can decrease the length of your credit history and increase your credit utilization rate, both of which can lower your credit score. In particular, we generally suggest you avoid closing your oldest credit card, since that long credit history is an asset you'll want to hang on to.

1. Sitting on Unpaid Parking Tickets

Some jurisdictions turn over unpaid parking tickets to collections agencies. Having an account in collections severely decreases your credit score. More and more municipalities have been sending unpaid parking ticket information to collection agencies recently, in an effort to close budget gaps.

This year, Chicago and the suburbs of Washington, D.C. have started pursuing unpaid tickets this way. New York City, which has nearly $700 million in overdue parking fines, does this, too. To find out if your city gives unpaid tickets to collections agencies, search on its .gov homepage or call the Department of Revenue. Keep in mind that this includes parking tickets you may have incurred as an out-of-state visitor!
