Yes, police do catch credit card thieves, but it often happens as part of larger investigations or through the thief getting caught for other crimes, rather than a single report leading to an immediate arrest, as small-dollar cases have low police priority; they are more often solved by tracking large fraud rings, working backward from found equipment, or relying on video/digital evidence that connects to other offenses.

How much cash can you put in the bank before it gets flagged?

You can deposit any amount of cash without being automatically flagged if it's under $10,000 in a single transaction, but banks must report deposits of $10,000 or more to the IRS via a Currency Transaction Report (CTR).

Is it safe to have $500,000 in one bank?

It's generally not fully safe to keep $500,000 in one bank account because the standard FDIC insurance limit is $250,000 per depositor, per bank, per ownership category, meaning $250,000 is at risk if the bank fails. To fully protect the entire $500,000, you need to structure it across different ownership categories (like single, joint, trust accounts) or use multiple banks to spread the funds, leveraging separate $250,000 coverage for each.

How much money can you deposit in a bank without getting questioned?

There's no legal limit on how much cash you can deposit into a bank account in the UK. But if you're planning to deposit a large sum, your bank might pause to ask where the money came from. This is because they need to follow anti-money-laundering (AML) rules designed to stop financial crime.

What bank account can the IRS not touch?

The IRS can generally levy any account in your name for unpaid taxes, but some funds are protected, like certain disability payments or Social Security (though some can be taken), and funds in an irrevocable trust or accounts not directly in your name (like some business or trust accounts) are harder to seize. Certain income sources are never taxed, like some veterans' benefits, child support, and welfare, but these aren't usually held in traditional bank accounts. The key is that the IRS targets your assets for your tax debt, so protecting funds by legally changing ownership or ensuring they are designated as non-taxable income is how they become untouchable by levy.
