If all the money that comes in and out of my account are by means of cheques and credit cards, can I still commit money laundering? If I'm not mistaken, paper trail is proof of innocence.
You can be charged. The criminal act is defined here and here. A core defining feature of violation of The Money Laundering Control Act of 1986 is knowing that the property involved in a financial transaction represents the proceeds of some form of unlawful activity, conducts or attempts to conduct such a financial transaction which in fact involves the proceeds of specified unlawful activity So if someone writes you a check funded by drug sales, then you have to worry about the reason for the check. Two of the reasons that will get you in trouble if the transaction is (i) with the intent to promote the carrying on of specified unlawful activity; or (ii) with intent to engage in conduct constituting a violation of section 7201 or 7206 of the Internal Revenue Code of 1986; Another reason would be knowing that the transaction is designed in whole or in part— (i) to conceal or disguise the nature, the location, the source, the ownership, or the control of the proceeds of specified unlawful activity; or (ii) to avoid a transaction reporting requirement under State or Federal law A "paper trail" if proof of nothing, it just makes it easier to get caught.
Your tax advisor was legally correct, but perhaps not very savvy. Unfortunately, the best way to resolve this sort of situation is to avoid it: You should have insisted your employer stop withholding for PA as soon as you moved out of state. Once someone else has possession of your money the burden is on you to get it back, and the burden can be (practically) quite high before it runs afoul of any serious laws. The fact is that your filings are correct, and the PA Department of Revenue is being ridiculous. If they can't be satisfied with reasonable and adequate evidence backing your return you can file administrative appeals at little cost in hopes of reaching a more reasonable agent. However, if I were in this situation, since NC's tax rate is higher, I would just amend my NC return to claim a credit for taxes paid (even though erroneously) to another state. (This takes advantage of our federalist system and your state citizenship and puts the burden on NC to collect the "correct" difference from PA if they care enough. You also don't have to fight for the actual return of money with your new state because presumably you will owe them taxes again this year, and if they haven't returned what you claim you're owed then you just deduct it from what you owe this year.)
It is legal for a company to ask for any information they want as a condition of doing business with you, so long as their request isn't proscribed by law. I don't know of any jurisdiction where a request for banking or credit information is illegal. (In this case, however, it does seem like you are being phished. You could report the matter to your country's consumer protection agency.)
You did not commit any crime, but that does not mean you cannot be charged with a crime. Up to the point where you take the item back out of your pocket, a police officer would have probable cause to believe you were attempting to steal the merchandise, and probable cause is all he would need to charge you. At trial, the government would have the burden of proving that you intended to actually steal the item, but it can satisfy that burden merely by showing that your actions were consistent with such an intention. You would have the option of testifying that you planned to pay for the item. From there, it would be up to a jury to decide whether it believes you. If so, you should be acquitted. If not, you would likely be convicted, and your conviction would likely be affirmed on appeal.
How come this is viable? Because it’s legal. What if people use their service to commit crimes? What if people use a Ford in a bank holdup? Or a Glock in a murder? Or the US Postal Service in a Nigerian letter scam? If the goods or services are legal and not provided for an obviously illegal purpose, nothing happens.
I can’t speak for Indonesia but if you did this in Australia you would be a criminal. You either committed fraud or are an accessory to fraud. You would probably be considered an accessory at and after the fact which means you are subject to the same maximum penalty as if you had committed the fraud yourself - 10 years in jail. In addition, you are liable to repay the money taken, jointly and severally with your ‘friend’. However, if they can only find you, you cannot recover from your ‘friend’ as you were engaged in a joint criminal enterprise. Scams such as you describe are distressingly common and many people fall for them. As such, assuming the court accepted your story (because you might actually be the fraudster and have just made it up) you would be unlikely to get close to the full sentence and if you caught the judge on a good day, might even escape jail. If you are lucky, the jury might acquit, even though, on the facts, they shouldn’t - juries do what juries do. If you’re really lucky the police might decide not to prosecute.
Is It Legally Binding? While their customer service sucks, your oral authorization of the charge is legally binding (I take payments that way almost every day in my own business, it isn't an unusual business practice in small professional businesses). You authorize oral authorization of payments over the phone in the credit card agreement that your credit card company sends you every year that you don't read and throw away. The provider has to collect more information for a credit card payment over the phone than they do for an in person swipe in a credit card machine (e.g. your credit card billing address) and they are fully responsible for wrongful charges if they deal with an imposter. By regularly checking your credit card statements, you can confirm that no incorrect charges are present. Tax Issues If you want to take a tax deduction for non-reimbursed medical expenses, you simply need to tote up the amounts your are entitled to from your own records, and put it in the appropriate box on your tax forms. You don't have to attach documentation to your return. If the IRS disputes your payment, you can offer up your credit card statements and your photograph of the receipts, and if necessary, medical records to show that you received the services, to show that the payment really happened and are deductible. Your credit card company's records, reflected in your monthly credit card statements, are considered very reliable for tax purposes. You have the burden of proving that the expense was incurred and is of a type that qualifies for a deduction by a preponderance of the evidence in the event that there is a dispute that is litigated, which means that you must show that it is more likely than not that you incurred a deductible expense of that kind in that amount in that tax year. Privacy Issues While there are financial information privacy issues associated with this transaction, HIPAA, which covers medical records, normally wouldn't apply to a credit card payment that indicates the person paid, the person paying, the account, the amount and the date, but not a description of the medical services provided or to whom they were provided, which is what is normally on a credit card receipt. The financial privacy issues are also partially addressed by the provider's merchant agreement with the credit card company which contains terms requiring them to maintain certain kinds of security with respect to your financial information (which is not to say that the provider actually follows all of the requirements of their merchant agreement scrupulously, which is why data breaches happen all the time in businesses both large and small).
What does the contract say? I write that so often I should get a stamp made. If the contract is silent, then it is implied that payment in US currency is acceptable, as is any other method of payment the parties agree to. As you have correctly quoted, there is no limit to the number of US coins that are valid for payments, unlike in many other jurisdictions where there is such a limit. Accept the coins, make the tenant wait while you count them one by one and then give them a receipt. Oh, and change your lease when you can to nominate sensible forms of payment like electronic transfer.
