You can spend cash up to $10,000 (or equivalent) in a single transaction without triggering an automatic report (like a Threshold Transaction Report in Australia or Form 8300 in the US) by financial institutions, but banks can still report any suspicious activity, even smaller amounts, to authorities like AUSTRAC or the IRS. The key is to avoid structuring, which means breaking down large sums into smaller deposits (e.g., several deposits under $10k) to evade reporting, as this itself is illegal and highly suspicious.
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.

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.
If you are traveling with an excess of $10,000, you must report it to a Customs and Border Protection (CBP) officer when you enter or exit the U.S. But there is no limit to the amount of money you can travel with.

Making multiple smaller cash deposits to avoid hitting $10,000 is called structuring, and it's illegal. Banks are required to report suspected structuring even if the amounts are well below the threshold. That's why deposits around $5,000 draw extra attention. They can look like the start of a pattern.

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.

A high volume of deposits, or transfers from other accounts, that are below £5,000 but add up to a much larger sum will quickly alert a bank to possible money laundering.
There's no limit to how much cash a family can bring into or out of the US, but if the combined total exceeds $10,000, it must be declared to US Customs and Border Protection (CBP). This $10,000 threshold applies to the family as a group, not per person.
