Free Guide to Opening a Joint Bank Account Online

What Is a Joint Bank Account and How It Works

A joint bank account is a deposit account that two or more people own together. Each account holder has equal rights to the money in the account, meaning any owner can deposit funds, withdraw money, or make decisions about the account without permission from the other owners. This differs from accounts where one person is authorized to act on behalf of another—in a joint account, all owners have full, independent access.

Joint accounts operate under one of two legal structures: "joint tenants with rights of survivorship" or "tenants in common." With survivorship rights, if one account owner passes away, their share automatically transfers to the surviving owner. With tenancy in common, a deceased owner's share becomes part of their estate and goes through probate proceedings. Most joint accounts default to survivorship unless you specifically choose otherwise.

According to the Federal Reserve, approximately 32 percent of couples maintain at least one joint account for household expenses. Joint accounts work well for families managing shared costs like mortgage payments, groceries, utilities, and childcare expenses. They also function effectively for parents managing accounts for adult children or for siblings managing elderly parents' finances.

The account itself operates like any other checking or savings account. You receive statements showing all transactions, can set up automatic bill payments, and access funds through debit cards, checks, and online transfers. However, the key difference is that all owners see all activity. There is no privacy between account holders—every deposit and withdrawal is visible to everyone with access.

Practical takeaway: Before opening a joint account, discuss with potential co-owners how you'll use the account, what happens if someone wants to close it, and whether you want survivorship protections included in the account structure.

Choosing the Right Bank and Account Type

When opening a joint account online, your first decision is selecting which institution to use. Banks, credit unions, and online-only financial institutions all offer joint accounts, each with different features and fee structures. Traditional banks with physical locations offer in-person support but typically charge monthly maintenance fees ranging from $10 to $25. Credit unions often charge lower fees or none at all, though they may require membership. Online-only banks frequently have zero monthly fees and higher interest rates on savings products, but provide no physical branch access.

The second decision involves choosing between account types. Joint checking accounts work for everyday transactions and bill payments. Joint savings accounts focus on accumulating funds with interest—according to the FDIC, the national average savings account rate is approximately 0.45 percent for regular savings and 4.50 percent for high-yield savings accounts as of 2024. Money market accounts combine checking and savings features with higher interest rates but require larger minimum balances. Some institutions offer joint money market accounts with rates around 4.75 to 5.00 percent, though these typically require deposits of $2,500 or more.

Location of the bank matters less now than it once did. Online banks process applications, issue debit cards, and transfer funds as quickly as traditional banks. However, if you need to deposit cash or checks frequently, online-only institutions may present challenges since they lack ATMs and deposit locations. Many online banks partner with ATM networks to provide access at thousands of locations, but this varies by institution.

Review the fee schedule carefully. Beyond monthly maintenance fees, consider overdraft fees (averaging $35 per incident), ATM fees at out-of-network machines ($2 to $3 per transaction), and fees for services like wire transfers or closing accounts early. Some institutions charge monthly fees only if you fall below a minimum balance—typically $500 to $5,000—so a joint account might help multiple people meet this requirement more easily.

Practical takeaway: List your banking habits—how often you visit ATMs, whether you deposit checks, how many transactions you typically make—then compare institutions based on their fee structures and features that match those habits.

Documents and Information You'll Need

Opening a joint account online requires specific documentation from each account holder. Banks must verify identity and confirm legal status to comply with Know Your Customer (KYC) regulations set by the Financial Crimes Enforcement Network (FinCEN). This process protects against fraud and financial crime.

Each person opening the joint account must provide a valid government-issued photo ID. This includes a driver's license, passport, state ID card, or military ID. The ID must be current and not expired. Some institutions scan the ID during the online process using a smartphone camera; others require uploading a photo of the front and back. A few banks still require mailing physical copies, though this is increasingly rare.

You'll also need your Social Security Number (SSN). Banks use this to pull your credit report and verify your identity against government databases. If someone doesn't have an SSN—which may apply to non-U.S. residents or certain visa holders—they may need to provide an Individual Taxpayer Identification Number (ITIN) instead. Some banks decline to open accounts for non-residents or those without these numbers; others have special programs.

Current contact information is required: a phone number, email address, and physical mailing address. Banks will send account numbers, debit cards, and statements to the mailing address. The phone number and email allow the bank to contact you about account activity and send security notifications. Some institutions verify phone numbers by sending a code via text message that you enter during the account opening process.

Proof of address may be requested, particularly if your ID is expired or doesn't show your current address. A utility bill, lease agreement, mortgage statement, or government mail with your name and current address works for this purpose. Most online banks request this only if other verification methods fail.

You may also need to provide information about your employment, income level, and occupation. Banks collect this for compliance purposes and to determine whether you qualify for certain account features or credit products. This information doesn't prevent you from opening an account; it merely creates a record of your account profile.

Practical takeaway: Gather all documents before starting the online application—valid ID for each person, SSN or ITIN numbers, current contact information, and a piece of mail showing your current address. Having these ready prevents interruptions during the application process.

Step-by-Step Process for Opening an Account Online

The online joint account opening process typically takes 15 to 30 minutes from start to finish. Most banks begin by asking you to select the type of account you want and the ownership structure. You'll specify that this is a joint account and designate whether you want survivorship rights included.

Next, the bank collects information about the first account holder. You'll enter your full legal name, date of birth, Social Security Number, phone number, email address, and physical address. Some institutions ask security questions at this stage—questions only you could answer, like your mother's maiden name or the city where you were born. These questions help prevent fraud if someone later tries to access your account.

The identity verification step follows. If using ID scanning technology, you'll take a photo of both sides of your driver's license using your phone camera. The system uses optical character recognition (OCR) to read the text from your ID and compares it against the information you entered. This usually takes under one minute. If the information matches, you move forward; if discrepancies appear, you may need to re-take the photo or provide additional documentation.

After the first owner's information is verified, the system asks for the second account holder's information. This person will typically receive an email or text message inviting them to complete their portion of the application. They'll enter their own identifying information and undergo the same verification process. Some institutions allow both people to complete the process simultaneously if you're opening the account together in person or online at the same time.

You'll then select funding options. Most online banks allow you to link an existing bank account to transfer your opening deposit electronically. You'll provide your current bank's routing number and account number—information found at the bottom of checks or in your current bank's online portal. The bank will then make two small test deposits (usually under $1 each) to verify the account information is correct. Once you confirm the deposit amounts, the link is established and you can transfer larger sums.

Some banks still accept checks by mail. You'll receive a deposit envelope with the account number printed on it; you mail a check to the bank's processing center, and funds appear in your account within 3 to 7 business days.

Before finalizing the account, you'll review and accept the account agreement and privacy policy. These documents outline fees, the bank's liability, your rights and responsibilities, and how
