Postdated checks: How do they work?

In this case, writing a postdated check with a future date on it might seem like an easy way to buy yourself some time, so the bank won’t transfer the funds before the cash is available.

Unfortunately, this doesn’t quite work.

Postdating a check doesn’t stop the recipient from cashing it or the bank from trying to take the money from your account, even if you don't have it. This can result in a pile of confusion — and fees.

Here’s why a postdated check won't necessarily delay a payment and probably makes a lousy Christmas gift — and some tips on how to successfully push payment dates later, if you need to.

What is a postdated check?

Written checks are a promise to pay a certain amount of money drawn from your bank account. When you fill out a check, there's a line for the date — and you usually put in the current day's date.

But with a postdated check, you simply write in some date in the future. It's not illegal — unless you have no intention of ever making good on the check.

While you can postdate a check to whatever date you like, banks and credit unions are not obliged to hold up a transaction.

Thanks to something called the Uniform Commercial Code, which has been implemented in many states, financial institutions may clear any check right away — even checks written for a future date.

When a check is signed, it becomes legal tender and can be processed immediately, explains the U.S. Consumer Financial Protection Bureau.

How to ensure your postdated check is delayed

The only way to make sure your postdated check won't get processed too soon is to notify both the bank and the recipient in writing.

If anything goes wrong, the letters will provide a paper trail that might protect you from consequences, like overdraft or late fees.

Before you start writing, make sure the person you’re paying will accept a postdated check.

If, for example, you're pretty sure your nephew will be OK with a postdated check in his Christmas stocking, then you can fill out the check with a date beyond Dec. 25. The same goes if your landlord says a postdated check will be all right for next month's rent.

Then, send or give the recipient the letter, specifying the date when the check should be cashed. Sign and date the note and make a copy for yourself.

Next, write your bank and ask for a "stop payment order" or a "postdated order" on your check. In some states, reasonably timed written notice is the only way to ensure a postdated check is processed according to your time table.

So you'll fee confident the bank will delay the correct check, your letter should clearly state:

• Your account number.
• The check number.
• The routing number.
• The name of the person or business receiving the check.
• The precise amount of the check, to the penny.

As long as the check hasn’t been processed yet, most banks will be able to postpone processing — although you may be charged a fee of about $20 to $35, or more. Ask your bank about its policy before you decide to go this route.

What if you don’t have enough funds for a check?

If your landlord or other recipient deposits the check and the funds aren’t available in your account, some banks will cover the check and pay out the money. Other banks will let the check bounce.

If the transaction goes through but you don’t have sufficient funds in your account, then your bank will charge you an overdraft fee.

If the check doesn’t go through, your bank will charge you a bounced-check fee (also known as an NFS or nonsufficient funds fee), and your recipient also may charge you a bounced-check fee — and maybe a late-payment fee, too.

It's not a crime to overdraw your bank account or accidentally bounce a check. But writing a bad check on purpose is considered fraud, which could bring a criminal charge.

Alternatives to writing a postdated check

Most people postdate checks in order to defer a payment — whether it’s for convenience or because they don't yet have the money.

Here are some better alternatives to using postdated checks.

Schedule payments using your bank’s online payment system. You can set up a single payment or recurring payments and choose the exact date(s) you’d like the money to go out. This is an easy way to control and monitor your bill payments.
