Yes, corporations can have interest-bearing checking accounts, but the options are more limited than for personal accounts

Most banks offer interest-bearing checking accounts designed for businesses, though they work differently than personal versions. A corporation's account earns interest on the balance you keep in it, just like a personal account does — but the interest rate is usually lower, the minimum balance requirement is higher, and the account comes with features built for business use rather than personal spending.

The catch is that many banks treat business checking and savings as separate products. Some banks will not pay interest on a checking account at all, no matter how much money sits in it. Others offer interest only if you move your money into a separate savings account or money market account. Before you open an account, you need to ask the bank directly whether they offer interest on the specific business checking product you want.

Key Takeaways

  • Banks offer interest-bearing business checking accounts, but not all banks do, and the rates are typically lower than personal savings accounts.
  • Many banks require a higher minimum balance to earn interest on a business checking account than they do for personal accounts.
  • Some banks separate business checking from savings entirely, meaning you earn interest only on money in a linked savings or money market account.
  • The interest rate and minimum balance vary by bank and by the account tier you choose, so comparing banks before opening is worth the time.
  • A corporation needs an Employer Identification Number (EIN) and business formation documents to open any business checking account.

How interest rates work on business checking accounts

Interest on a business checking account is calculated the same way as on a personal account: the bank takes your daily balance, applies the annual interest rate, and deposits the earnings monthly or quarterly. If you keep $50,000 in the account and the rate is 0.05% per year, you earn about $25 annually — paid in small increments throughout the year.

The rate itself is the real variable. Personal checking accounts sometimes offer 4% to 5% on balances up to a certain limit, but business accounts rarely do. Most banks pay between 0.01% and 0.50% on business checking, depending on the account type and your balance. Some accounts tier the rate — meaning you earn a higher percentage on larger balances. A bank might pay 0.10% on the first $25,000 and 0.25% on anything above that.

Interest rates change when the Federal Reserve changes its benchmark rate, which happens several times a year. When rates rise, your bank's rates usually rise too, but with a delay. When rates fall, your bank's rates fall faster. This means the rate you see today may not be the rate you earn six months from now.

Minimum balance requirements for business accounts

Most banks require you to keep a minimum balance in a business checking account to earn any interest at all. This minimum is often $2,500 to $10,000, though some banks ask for $25,000 or more. If your balance drops below the minimum on any day, you may lose the interest for that entire month, or the rate may drop to zero.

A few banks waive the minimum if you meet other conditions — for example, if you set up direct deposit of payroll, maintain a linked savings account, or use the bank's credit card. Read the account terms carefully, because the minimum balance rule is where banks hide the real cost of the account.

Business checking versus business savings for interest earnings

Many banks do not pay interest on checking accounts at all, even for businesses. Instead, they offer a separate business savings account or money market account that earns interest. The checking account is for spending and transactions; the savings account is for storing money and earning a return.

This split makes sense for a bank's accounting, but it means you have to move money between accounts to earn interest. Some banks let you link the accounts so transfers are when ready and free. Others charge a fee for each transfer or limit how many you can make per month.

Before opening a business checking account, ask the bank: "Does this checking account earn interest, or do I need a separate savings account to earn interest?" The answer will tell you whether you are looking at one account or two.

What you need to open a business checking account

A corporation needs more paperwork than a person opening a personal account. You will need your Employer Identification Number (EIN), which the IRS issues to all businesses. You will also need your Articles of Incorporation or Certificate of Formation — the legal document that created your corporation.

The bank will ask for a government-issued ID for at least one owner or authorized signer, and may ask for a business license or tax return to verify that the business is real. Some banks also require a resolution from your board of directors authorizing someone to open the account and sign checks.

If your corporation is new and does not have an EIN yet, you can explore for one online at the IRS website (irs.gov) in about 15 minutes. The number is issued when ready. You do not need to wait for a letter in the mail to open a bank account.

Interest-bearing checking versus other ways to store business cash

An interest-bearing checking account is not the only way to earn a return on business cash. A business savings account usually pays more interest than checking, but you cannot write checks from it. A money market account is a hybrid — it pays more than checking but less than savings, and it lets you write a limited number of checks per month.

A business money market account might pay 0.40% while checking pays 0.05%, but the money market account may require a $10,000 minimum and limit you to three checks per month. For a business that needs to access cash frequently, checking makes sense even at a lower rate. For a business that can leave money untouched, savings or money market may be worth the restrictions.

Some businesses use both: a checking account for daily operations and a savings account for reserves. Money moves from savings to checking as needed, and interest accrues on the larger balance sitting in savings.

Where to find business checking accounts that pay interest

Not all banks advertise interest rates on business checking prominently. Online banks and credit unions are more likely to offer competitive rates than large national banks, but you have to check each one individually.

Start by calling or visiting the websites of banks where you already have a personal account — they may offer better rates to existing customers. Then check online banks that focus on business accounts, and ask your local credit union whether they offer business checking with interest. When you compare, write down the interest rate, the minimum balance, and any fees for falling below the minimum.

The difference between 0.05% and 0.40% does not sound large, but on a $100,000 balance, it is the difference between $50 and $400 per year. For a business with larger balances, that gap widens.

Frequently Asked Questions

Does my corporation lose the interest if I dip below the minimum balance for one day?

It depends on the bank's policy. Some banks calculate interest on your average daily balance throughout the month, so one day below the minimum does not cost you. Others use the lowest balance method, where falling below the minimum even once means you earn zero interest for that month. Read the account disclosure before you open the account, or call and ask directly.

Can I earn interest on a business checking account if I have multiple owners?

Yes. The account itself earns interest regardless of how many people can sign checks or access it. The bank will ask for identification and authorization from each owner, but that does not change the interest rate or how it is calculated.

What happens to the interest if I close the account mid-month?

You receive interest earned up to the day you close the account. The bank calculates it based on your balance through the closing date and deposits it before the account closes, or includes it in your final statement.

Is the interest I earn on a business checking account taxable?

Yes. Your corporation must report all interest earned as income on its tax return. The bank will send you a Form 1099-INT at the end of the year showing how much interest you earned. This is a question for your accountant or tax preparer, not the bank.

Can I move money between my business checking and savings account without losing the interest?

Yes, transfers between your own accounts do not affect interest. Interest is calculated on the balance in each account separately. Moving money from checking to savings does not cost you interest — it just changes which account the money is in.
