What Square Does and How It Moves Money

Square is a payment processor that lets businesses accept card payments in person, online, or through invoices. When a customer swipes, taps, or enters a card at a Square terminal or website, Square captures that transaction, routes it through the card networks (Visa, Mastercard, American Express, Discover), and deposits the funds into the business owner's bank account. The money does not go to Square first — it flows from the customer's bank through the card network to the business's bank, with Square taking a cut along the way.

Square makes money by charging a percentage of each transaction plus a small flat fee. For in-person card payments, that is typically 2.6% plus 10 cents per transaction. For online payments, it is 2.9% plus 30 cents. Square also charges monthly fees for certain services like payroll or invoicing software, and hardware costs if you buy a reader or terminal. Understanding these fees matters because they reduce what the business owner actually receives from each sale.

Key Takeaways

  • Square charges a percentage of each transaction (usually 2.6% for in-person, 2.9% for online) plus a flat fee, and these costs come out before the business owner sees the money.
  • Funds typically arrive in the business owner's bank account within one to two business days, though timing depends on the bank and the time of day the transaction occurs.
  • Square holds onto a small reserve of funds from transactions as protection against chargebacks and refunds, which can delay access to a portion of revenue.
  • The card networks (Visa, Mastercard, etc.) and the customer's bank also take fees from the transaction, which Square does not control and cannot reduce.
  • Square reports all transaction data to the IRS on Form 1099-K if annual volume exceeds certain thresholds, so business owners need to track and report this income.

How Money Moves From Customer to Business Owner

The path a payment takes involves multiple stops. When a customer pays with a card at a Square terminal, the terminal sends the card details to Square's servers. Square then contacts the customer's card issuer (their bank) to verify the card is valid and the account has sufficient funds. If approved, the card issuer sends an authorization code back to Square, and Square sends a receipt to the terminal.

At this point, the transaction is authorized but not yet settled. Settlement happens at the end of the business day when Square batches all the day's transactions and sends them to the card networks. The networks then instruct the customer's bank to transfer the money. That transfer goes to Square's bank account first, then Square deposits the business owner's portion (minus fees) into their designated bank account. This entire process usually takes one to two business days, though some banks are slower than others.

If a customer disputes the charge or requests a refund, the money can flow backward through the same route. The business owner's bank account gets debited, and the funds return to the customer's card issuer. This is why Square holds a reserve — to cover these reversals without the business owner going negative.

Square's Fees and What They Cover

Square's standard in-person rate of 2.6% plus 10 cents covers the cost of processing the transaction, but it also includes Square's profit margin. That percentage goes to multiple parties: the card networks take a small cut, the customer's bank takes a cut (called interchange), and Square keeps the remainder. Square does not publish exactly how much each party receives, but interchange typically accounts for 1% to 2% of the transaction.

Online transactions cost more (2.9% plus 30 cents) because they carry higher fraud risk. Square cannot see the customer's face or verify their identity in person, so the card networks charge higher interchange rates for online sales. Square passes this cost along to the business owner.

Beyond per-transaction fees, Square charges for optional services. Square Payroll costs $99 per month plus $5 per employee per pay period. Square Invoices is free for basic use but charges 2.9% plus 30 cents if the customer pays by card. Square Hardware — readers, terminals, and stands — ranges from $29 for a basic card reader to $399 for a full point-of-sale terminal. Monthly subscription plans for Square's point-of-sale software start at $60.

When Money Actually Arrives in the Bank Account

Square deposits funds on a schedule that depends on when the transaction settled and which bank the business owner uses. Most deposits arrive within one to two business days. A transaction completed on Monday morning might arrive Tuesday or Wednesday. A transaction on Friday evening might not arrive until Monday or Tuesday, depending on the business owner's bank and whether the weekend falls in between.

Square offers next-day deposits for an additional fee in some cases, though this is not standard. The business owner's bank also plays a role — some banks hold deposits for an extra day or two before making them available. If the business owner uses a small or regional bank, deposits may take longer than if they use a major national bank.

Square also holds a rolling reserve on a portion of transactions. This reserve is typically 1% to 5% of daily volume, held for 7 to 30 days. The reserve protects Square against chargebacks and refunds. If a customer disputes a charge 60 days after the transaction, Square can pull the funds from this reserve to cover the refund. The business owner eventually gets this money back, but only after the reserve period ends and no disputes have been filed.

Chargebacks and Disputes

A chargeback occurs when a customer contacts their bank and claims they did not authorize the charge or did not receive what they paid for. The bank then reverses the transaction, pulling the money back from Square's account. Square deducts the full transaction amount plus a chargeback fee (usually $15) from the business owner's account. If the business owner does not have enough funds, their account can go negative.

Square gives business owners a chance to dispute the chargeback by providing evidence — a receipt, a shipping confirmation, a signed contract, or a message from the customer acknowledging the purchase. If the business owner wins the dispute, the money is restored and the chargeback fee is waived. If they lose, the money stays gone.

High chargeback rates can get a business owner flagged. If chargebacks exceed 1% of transactions in a month, Square may require a higher reserve, charge additional fees, or in extreme cases, close the account. This is why businesses need to keep good records and respond quickly to disputes.

Reporting to the IRS and Tax Implications

Square reports all transaction data to the IRS on Form 1099-K if the business owner processes more than $5,000 in a calendar year. This threshold has been subject to change — the IRS has proposed raising it to $20,000 — so business owners should check current rules. The 1099-K reports the total volume of transactions, not the net amount after fees.

This matters because the business owner owes income tax on the full transaction amount, not just what Square deposited. If a business owner processes $100,000 in sales but pays $2,600 in Square fees, they still report $100,000 as income. The fees are deductible as a business expense, but the business owner has to track and report them separately.

Square provides a year-end summary in the business owner's account, and they can read transaction reports at any time. Keeping these records organized makes tax filing easier and helps if the IRS ever questions the business owner's reported income.

Frequently Asked Questions

Can I get my money faster than one to two days?

Standard deposits take one to two business days. Some banks offer faster clearing, and Square occasionally offers expedited deposits for a fee, but this varies by account type and bank. Weekends and holidays slow deposits because the banking system does not process transfers on those days.

What happens if a customer does a chargeback after I have already spent the money?

Square pulls the full transaction amount plus a $15 fee from your bank account. If you do not have enough funds, your account goes negative and you owe Square the difference. You can dispute the chargeback with evidence, but until it is resolved, the money is gone from your account.

Do I have to report Square income to the IRS?

If you process more than $5,000 per year, Square sends you a 1099-K and reports the same information to the IRS. You must report this income on your tax return. Even if you process less than $5,000, you still owe income tax on all revenue — the 1099-K threshold only determines whether Square reports it to the IRS.

Why does Square hold a reserve if I have been a customer for years?

The reserve protects Square against chargebacks and refunds, which can happen months after a transaction. Even reliable businesses occasionally have customers dispute charges or request refunds. The reserve size depends on your chargeback history and transaction volume, not how long you have been a customer.

Can I use Square if I do not have a business bank account?

Square can deposit funds into any bank account in your name, including a personal checking account. However, mixing personal and business funds makes accounting and taxes harder. Most accountants recommend opening a separate business account to keep records clear.
