You can deposit large amounts of cash in a year, but single deposits over $10,000 (or equivalent) trigger mandatory reporting to government agencies (like the IRS in the U.S. or AUSTRAC in Australia) via Currency Transaction Reports (CTRs) or similar forms, requiring banks to document the source, while structuring deposits (breaking large amounts into smaller ones to avoid reporting) is illegal and carries severe penalties, so it's best to deposit legally and be prepared to show proof of funds.
You must submit a TTR to AUSTRAC for each individual cash transaction of A$10,000 or more. If you suspect your customer is structuring their transactions to avoid the TTR reporting threshold, or is transacting with proceeds of crime, you must submit a suspicious matter report (SMR) to AUSTRAC.
Banks must report cash deposits of $10,000 or more. Don't think that breaking up your money into smaller deposits will allow you to skirt reporting requirements. Small business owners who often receive payments in cash also have to report cash transactions exceeding $10,000.
The cash limit set per day, per transaction, and from one person is ₹2 lakhs. On the other hand, the cash deposit limit in a Savings Account per financial year is set at ₹10 lakhs. Your bank will report a transaction that exceeds this limit to Income Tax authorities.

The RBI has set a cap of ₹2 lakh for cash deposits made in a day, per transaction, and from a single person under section 269ST. The most significant number you must remember is the annual limit. In a financial year, the cash deposit limit in a savings account is capped at ₹10 lakh.
The IRS reporting threshold: The $10,000 rule
¹ This applies to cash deposits, wire transfers, and other large financial movements. But this rule isn't about taxing you — it's part of anti-money laundering laws designed to flag suspicious activity.
The ₹10 Lakh Cash Deposit Rule
At the heart of the discussion lies the widely known ₹10 Lakh Rule. Under current regulations, if the total cash deposits in a savings account exceed ₹10 lakh during a financial year, the bank is required to report this activity to the Income Tax Department.

It's not just lump sum cash deposits that can raise flags. Several related deposits that equal more than $10,000 or several deposits over $9,800 can also trigger a bank's suspicion, causing it to report the activity to FinCEN.
Many banks don't limit the amount of cash you can deposit. However, depositing more than $10,000 will subject your deposit to extra rules and regulations from the bank and the federal government.

When conducting an audit, the Australian Taxation Office (ATO) can obtain access to any reports made to AUSTRAC about cash transactions of $10,000 or more.
Your bank must report the deposit to the federal government. That's because the IRS requires banks and businesses to file Form 8300 and a Currency Transaction Report, if they receive cash payments over $10,000. Depositing more than $10,000 will not result in immediate questioning from authorities, however.
Australia's new cash laws, effective January 1, 2026, mandate that major grocery and fuel retailers must accept cash for in-person purchases up to $500 between 7 am and 9 pm, ensuring essential goods remain accessible, though small businesses with under $10m turnover are generally exempt. These regulations aim to support cash-reliant Australians but don't apply to all businesses, with specific rules for essential items and transaction times.
Banks do not have a requirement (known to the public) to file a report unless someone deposits more than $10,000 at one time, but they keep records and likely have other thresholds to report. For example, to keep track of possible structuring of deposits to avoid ever depositing $10,000.
Deposits over $10,000 are treated a little differently by banks because of a law called the Bank Secrecy Act. Under this law, when you make a cash deposit of $10,000 or more, the bank is required to file a Currency Transaction Report (CTR). The CTR needs to include: The name of the person who is making the deposit.
