Do banks maintain records of the total deposits made into an account over a specific time period?

Yes, you can obtain a one-year bank account statement specifically for deposits into your account. Here's how:

1. Online banking: Many banks offer this feature through their online platforms. You may be able to generate the statement yourself.

2. Customizable filters: Some banks allow you to apply filters based on transaction types. For example, in the US, you might be able to filter for:

• FedWire In
• ACH In
• SWIFT In

(Note that these terms may vary depending on your country's banking system)

3. Direct request: If you can't access this information online, you can simply ask your bank for a one-year statement showing only deposits.

This type of statement request is a common service offered by banks, so you should have no trouble obtaining the information you need.
