Yes, corporations can open interest-bearing checking accounts, but the account type and interest rate depend on your business structure and the bank you choose

Most banks offer interest-bearing business checking accounts to corporations, though the interest paid is typically lower than what you would see on a savings account or money market account. The account works like a standard business checking account — you write checks, use a debit card, make deposits — but the bank pays you a small percentage on your daily balance.

The catch is that interest rates on business checking accounts are usually very low, often between 0.01% and 0.25% annually, depending on the bank and your balance. Some banks pay no interest at all on business checking. If you need meaningful returns on cash reserves, a separate business savings account or money market account will earn more, but those accounts typically limit how many withdrawals you can make per month.

The bank you choose matters more than the account type. Large national banks often pay little to no interest on business checking, while some online banks and credit unions offer slightly higher rates. You will need to compare what different institutions offer before opening an account.

Key Takeaways

  • Corporations can open interest-bearing business checking accounts at most banks, though the interest rate is usually very low — typically under 0.25% per year.
  • You will need your Employer Identification Number (EIN), corporate bylaws or articles of incorporation, and identification for the person authorized to open the account.
  • Online banks and credit unions often pay higher interest on business checking than large national banks do.
  • If you want better returns on cash reserves, a separate business savings or money market account will earn more interest, though with withdrawal limits.

What documents you need to open a corporate checking account

Banks require proof that your corporation exists and that you have authority to open an account on its behalf. Bring your Employer Identification Number (EIN) — the federal tax ID for your business — along with your articles of incorporation or corporate bylaws. Some banks also ask for a corporate resolution, which is a document signed by your board stating that you are authorized to open the account.

You will also need a government-issued ID for the person who will be the account owner or authorized signer. If multiple people will have access to the account, the bank will ask for ID and signatures from each of them. Some banks require this in person; others allow you to submit documents online or by mail.

If your corporation is very new and you do not yet have an EIN, you can obtain one immediately from the IRS website or by phone. The process takes a few minutes and you can use the number right away, even before you receive the official letter in the mail.

How interest rates on business checking accounts compare

Interest rates on business checking vary widely by bank and by the balance you maintain. A large national bank like Chase or Bank of America typically pays 0.01% or less on business checking, meaning a $10,000 balance would earn roughly $1 per year. Online banks like Axos or Lendingclub often pay 0.25% to 0.50%, which would earn $25 to $50 per year on that same $10,000.

Credit unions sometimes offer higher rates on business checking than banks do, particularly if you are a member. However, credit union rates also vary by institution and by the minimum balance required. You will need to contact credit unions in your area to compare their current offers.

Keep in mind that interest rates change frequently and are set by each bank independently. The rate you see today may be different in six months. If earning interest on your checking account is important to your business, check the current rates at several banks before you decide where to open your account.

Interest-bearing checking versus other business savings options

An interest-bearing checking account gives you the convenience of a checking account — unlimited deposits and withdrawals, check writing, debit card access — but with minimal interest. If you have cash reserves that you do not need to access frequently, a business savings account or business money market account will earn more interest, often 4% to 5% annually at online banks, though rates fluctuate.

The trade-off is that savings and money market accounts typically limit you to six withdrawals per month (though this rule has been relaxed at many banks in recent years). If you need to access your cash regularly for business operations, a checking account is the right choice even if the interest is low. If you have money you want to set aside and leave untouched, a savings account will earn significantly more.

Some businesses use both: a checking account for day-to-day operations and a linked savings account for reserves. Money can move between them easily, and you earn better interest on the portion you are not spending immediately.

Minimum balance requirements and monthly fees

Most business checking accounts require a minimum balance to avoid a monthly fee, though the amount varies. Some banks require $500, others $2,500 or more. If your balance falls below the minimum, you may be charged a fee of $10 to $25 per month. Interest-bearing accounts sometimes have higher minimums than non-interest-bearing ones.

Online banks often have lower or no minimum balance requirements, which can make them a better choice for small corporations or startups. However, they may charge fees for things like wire transfers or paper statements that brick-and-mortar banks include for free.

Before you open an account, ask the bank for a complete fee schedule and find out what the minimum balance requirement is. Calculate whether the interest you will earn actually exceeds the fees you might pay — at very low interest rates, it often does not.

How to compare banks and choose the right account

Start by listing the banks and credit unions available in your area or online. For each one, note the current interest rate on business checking, the minimum balance requirement, and any monthly fees. Then calculate: if you keep an average balance of what you expect to have, how much interest will you earn per year, and how much will you pay in fees?

Consider also whether you need in-person branch access or whether online banking is sufficient. If you deposit cash frequently, a bank with physical branches may be more convenient. If you mostly transfer money electronically, an online bank can work well and often pays higher interest.

Once you have narrowed your choices to two or three banks, contact them directly to confirm current rates and ask any questions about the account. Rates and terms change, so what you see on their website may not be exactly what you get when you apply.

Frequently Asked Questions

Do I need a separate business checking account, or can I use a personal account?

You should use a separate business account. Mixing personal and business money makes tax filing harder and can create legal problems if your corporation is ever sued. Banks also have different rules for business and personal accounts, and a personal account will not give you the same protections for business transactions.

Can I earn interest on a business checking account if I have a very small balance?

Yes, but the amount will be tiny. If a bank pays 0.25% and you keep $1,000 in the account, you will earn about $2.50 per year. If there is a monthly fee of $5, you will actually lose money. For small balances, look for banks with no minimum balance requirement and no monthly fees.

What if I want to move my account to a different bank later?

You can close the account and open a new one at any time. The bank will not charge you for closing, though some may require you to maintain a minimum balance for a certain period. If you have automatic payments or direct deposits set up, you will need to update those with your new account number before you close the old account.

Do online banks offer the same protections as traditional banks?

Yes, as long as they are FDIC-insured, which most are. FDIC insurance protects your deposits up to $250,000 per account category. Check the bank's website to confirm they are FDIC-insured before you open an account.

Can I earn interest if my corporation is an LLC or S-corp instead of a C-corporation?

Yes. Most banks offer interest-bearing business checking to all business structures — corporations, LLCs, partnerships, and sole proprietorships. The documents you need and the process are slightly different depending on your structure, but the account itself works the same way.
