A direct deposit is an electronic payment sent straight into your bank or credit union account over the ACH network, instead of a paper check. Employers use it for payroll, and Nacha, which governs the ACH Network, lists tax refunds, government benefits, payment app payouts, expense reimbursements, bonuses and commissions as other common uses.
​

To set it up, you give the payer two numbers: your bank's routing number and your account number. Nacha says those are the two pieces of information you need. Once the payer's system is updated, each payment lands in your account on the scheduled date without a trip to the bank.
​

Direct deposit runs on the ACH network. Your employer or its payroll provider sends a file of payment instructions to its bank. That bank passes the entries through an ACH operator to your bank, which reads the routing and account numbers and credits your account on the settlement date the payer chose.
​

In ACH terms, the employer's bank is the originating institution and your bank is the receiving institution. The routing number tells the network which bank receives the entry, and the account number tells your bank whose account to credit. The Federal Reserve Banks operate FedACH as one ACH operator and publish a routing directory of institutions that can receive ACH entries.
​

Because the payment is scheduled in advance, payroll deposits tend to arrive on the same day every pay period. Nacha describes direct deposit as delivering salaries each payday along with Social Security and veterans benefits.
​

Ask your employer or payer whether it offers direct deposit, then give it your routing number, account number and account type. Most employers use an online payroll portal or a paper authorization form. Some banks can prefill the form or connect to your payroll provider from the banking app.

As one bank example, Bank of America lets customers set up direct deposit from its mobile app by finding their employer or payroll provider, or by downloading a prefilled form from Online Banking. The bank says you will need your account and ABA routing numbers plus your employer's name and address.
​

A direct deposit authorization form asks for your name, your bank's name, the nine digit routing number, your account number, and whether the account is checking or savings. Many forms also ask for an amount or percentage if you split deposits, plus your signature and sometimes a voided check.
​

Nacha describes a Split Deposit feature: you can ask that a percentage go to checking and the rest to savings, for example 85% and 15%, or send a set dollar amount to savings. Double check the account number digit by digit, since a typo is the most common reason a first deposit bounces back to the payer.
​

Federal rules require your bank to make an electronic deposit available by the business day after the banking day it receives the funds. Many banks post payroll the same day it arrives. When your first deposit starts depends on your employer's payroll cycle, so the first payday after you sign up may still be a paper check.
​

The CFPB says your bank or credit union must make direct deposit funds available on the next business day after the business day it received them, and adds that many institutions make payroll funds available immediately. The underlying rule is Regulation CC, 12 CFR 229.10(b), which covers electronic payments and applies once the bank has received actually and finally collected funds.
​

Some banks advertise early direct deposit, posting pay before the official payday when the payroll file arrives early. That is a bank policy, not a federal rule, so check your own bank's terms.
​

Yes. The IRS deposits refunds into checking, savings and some retirement accounts when you enter your routing and account numbers on your return. You can split a refund across up to three accounts. There is a cap on how many electronic refunds a single account can receive in a year.
​

The IRS says it issues more than nine out of ten refunds in less than 21 days, and that you can deposit a refund into one, two or three accounts using Form 8888 if you file on paper. The same IRS page says no more than three electronic refunds can go into a single account or prepaid debit card, and anyone over that limit receives a notice and a paper refund.
​

Most US salaried and hourly employees, Social Security and veterans benefit recipients, and taxpayers getting refunds. Usage is lower among gig workers, who are often paid through apps or platforms instead of payroll. Payment apps themselves often move money to bank accounts using direct deposit.
​

In a study it commissioned, Nacha reported in October 2022 that 97% of workers ages 22 to 34 had a bank or credit union account and 83% were paid by direct deposit. The same Nacha release found 88% of W2 employees in that group used direct deposit, compared with 47% of gig workers.
​

Direct deposit depends on correct numbers and on the payer's schedule. A wrong digit can delay pay for a cycle, switching banks means updating every payer, and ACH settles on business days only. It also requires a bank or credit union account, which not every worker has.
​

Three limits are worth planning for. First, changes take effect only after the payer processes them, so keep your old account open until the first deposit lands in the new one. Second, ACH does not settle on weekends or bank holidays, so a payday that falls on one may shift. Third, people without an account cannot use it, which is part of why Nacha found lower usage among gig workers.
​

Direct deposit is one type of ACH payment: a credit pushed into your account. ACH also carries debits such as bill payments.
​

Yes, if your employer supports it. Nacha describes splitting by percentage or a set dollar amount.
​

Only if the form asks for one. Some banks, such as Bank of America, offer a prefilled form or app setup instead.
​

By the next business day after your bank receives it, per the CFPB, and often the same day.
​

Nacha suggests asking your employer to consider offering it.
