Does opening bank accounts hurt your credit?

Two different reports get mixed up in this question, and only one of them is a credit report.

Does a checking account touch your credit score?

No. A credit score is built from borrowing: cards, loans, whether you paid them. A checking or savings account is money you hold, not money you owe, and deposit accounts are not reported to the credit bureaus. Some banks run a soft inquiry to confirm your identity when you apply, and a soft inquiry does not move a score.

So opening a fourth checking account this year has the same effect on your credit score as opening none.

Then what does the bank check?

A different report. The CFPB describes specialty consumer reporting companies that "collect information and provide reports about how consumers use their deposit accounts", and the best known of them is ChexSystems. ²

What they record is negative deposit history. The CFPB's examples are an "unpaid negative balance on that account, such as from an overdraft", account closures the bank initiated, and suspected fraud or bad-cheque history. ¹ An account you opened, used as the terms required, and closed at zero is not on that list.

How long does it stay on the report?

The CFPB states that these companies "can't include most negative information that's more than seven years old", and notes that some disregard information after five years in practice. ¹ That is the same outer limit the credit bureaus work to, and it is why an old overdraft can still block a new account.

Where bonus chasing can go wrong

Not in the opening. In the closing.

The habit that lands on a checking account report is leaving a small negative balance behind: a monthly fee that posted after you emptied the account, an overdraft from a forgotten subscription, a returned deposit. The bank charges it off, closes the account, and reports the closure. Seven years later a different bank reads it.

So before you close any account:

1. Cancel every recurring debit pointed at it and wait one cycle.
2. Confirm the balance is exactly zero after the last fee has posted.
3. Close it in writing and keep the confirmation.

What if you are denied?

The bank must give you an "adverse action" notice that "includes the name and contact information of the checking account reporting agency". ¹ You are then entitled to a free copy of the report, on top of the free copy you can request every twelve months anyway. ^{1 2} If something on it is wrong, dispute it with the reporting company: under the Fair Credit Reporting Act it must conduct a reasonable investigation free of charge. ³

What this looks like in CardLab

An offer's terms sometimes name a deposit-account screening as a condition of opening, and CardLab prints that on the offer when the page says so. The bonus tracker's safe-to-close date is the other half: closing on that date, at zero, is what keeps the next application clean.
