Direct deposit moves money electronically from a payer's account to a payee's account. It is used for payroll, Social Security benefits, tax refunds, and vendor payments. The payer initiates the transfer through the ACH network. The money appears in the payee's account on the scheduled date. No paper check, no trip to the bank, no hold.

The system is faster and safer than paper checks. Checks can be lost, stolen, or forged. Direct deposit cannot be intercepted in the same way. It also saves money. The federal government switched to electronic payments for benefits in the 1990s, saving millions in check printing and postage. Employers save too. A single direct deposit file can pay thousands of employees at once.

Setting up direct deposit is simple. You provide your employer or payer with your bank routing number and account number. They enter it into their payroll system. The first payment may take a cycle or two to process. After that, the money arrives on schedule. If you change banks, you must update the information with each payer. Missing a update can delay your pay.

Direct deposit is not instant. It goes through the ACH network, which settles in one to three business days. Some employers offer early access to wages through apps like Chime or DailyPay, which advance funds before the scheduled deposit. Those services can help with cash flow, but they may charge fees. Direct deposit itself is usually free.
