How to prevent misusing my Account details
This is more legal and less personal finance question. You should immediately lodge a police complaint mentioning that some persons are using your PAN card details for activities not authorized by you. In the meantime also engage the services of a CA and reply back to income tax authorities. Do not ignore the notice.
"According to an article on Bankrate.com from 2011, yes, it can hurt your credit: With individual liability accounts, the employee holds all responsibility for the charges, even if the company pays the issuer directly. Joint liability means the company and employee share the responsibility for payments, says Mahendra Gupta, author of the RPMG survey. In both cases, if the card isn't paid and the account becomes delinquent, it will pop up on the employee's credit report and dent his or her credit score, says Barry Paperno, consumer affairs manager at myFICO.com. It doesn't matter if the company was supposed to make the payment; the repercussions fall on the employee. ""It will impact your score no differently than if you were late on one of your own accounts,"" Paperno says. Usually, with corporate credit cards, the employee is liable along with the employer for charges on the card.  The intent is to provide the employee with an incentive not to misuse the card.  However, this can be a problem if your company is late in paying bills. In the distant past, I had a corporate credit card.  I was not supposed to have to pay the bill, but I did receive a bill in the mail every month.  And occasionally, the payment was late.  In my case, these late payments never showed up on my credit report.  I can't remember now whether or not this card was reported on my credit report at all.  And I remember being told when I got the card that I was jointly responsible for the card with the company. However, your experience may be different.  Do the on-time payments show up on your credit report?  If so, that may be an indication that a late payment might appear." In my opinion, every person, regardless of his or her situation, should be keeping track of their personal finances.  In addition, I believe that everyone, regardless of their situation, should have some sort of budget/spending plan. For many people, it is tempting to ignore the details of their finances and not worry about it.  After all, the bank knows how much money I have, right?  I get a statement from them each month that shows what I have spent, and I can always go to the bank's website and find out how much money I have, right?  Unfortunately, this type of thinking can lead to several different problems. Overspending.  In olden days, it was difficult to spend more money than you had.  Most purchases were made in cash, so if your wallet had cash in it, you could spend it, and when your wallet was empty, you were required to stop spending.  In this age of credit and electronic transactions, this is no longer the case.  It is extremely easy to spend money that you don't yet have, and find yourself in debt.  Debt, of course, leads to interest charges and future burdens. Unpreparedness for the future.  Without a plan, it is difficult to know if you have saved up enough for large future expenses.  Will you have enough money to pay the water bill that only shows up once every three months or the property tax bill that only shows up once a year?  Will you have enough money to pay to fix your car when it breaks?  Will you have enough money to replace your car when it is time?  How about helping out your kids with college tuition, or funding your retirement?  Without a plan, all of these are very difficult to manage without proper accounting.   Anxiety.  Not having a clear picture of your finances can lead to anxiety.  This can happen whether or not you are actually overspending, and whether or not you have enough saved up to cover future expenses, because you simply don't know if you have adequately covered your situation or not.  Making a plan and doing the accounting necessary to ensure you are following your plan can take the worry out of your finances. Fear of spending.  There was an interesting question from a user last year who was not at all in trouble with his finances, yet was always afraid to spend any money, because he didn't have a budget/spending plan in place.  If you spend money on a vacation, are you putting your property tax bill in jeopardy?  With a good budget in place, you can know for sure whether or not you will have enough money to pay your future expenses and can spend on something else today. This can all be done with or without the aid of software, but like many things, a computer makes the job easier.  A good personal finance program will do two things: Keeps track of your spending and balances, apart from your bank.  The bank can only show you things that have cleared the bank.  If you set up future payments (outside of the bank), or you write a check that has not been cashed yet, or you spend money on a credit card and have not paid the bill yet, these will not be reflected in your bank balance online.  However, if you manually enter these things into your own personal finance program, you can see how much money you actually have available to spend. Lets you plan for future spending.  The spending plan, or budget, lets you assign a job to every dollar that you own.  By doing this, you won't spend rent money at the bar, and you won't spend the car insurance money on a vacation. I've written before about the details on how some of these software packages work.  To answer your question about double-entry accounting: Some software packages do use true double-entry accounting (GnuCash, Ledger) and some do not (YNAB, EveryDollar, Mvelopes).  In my opinion, double-entry accounting is an unnecessary complication for personal finances.  If you don't already know what double-entry accounting is, stick with one of the simpler solutions. This answer fills in some of the details you are unsure about, since I'm further along than you. I bought the ESPP shares in 2012.  I didn't sell immediately, but in 2015, so I qualify for the long-term capital gains rate. Here's how it was reported: The 15% discount was reported on a W2 as  it was also mentioned twice in the info box (not all of my W2's come with one of these) but also  This showed the sale trade, with my cost basis as the discounted price of $5000. And for interests sake, I also got the following in 2012: WARNING! This means that just going ahead and entering the numbers means you will be taxed twice! once as income and once as capital gains. I only noticed this was happening because I no longer worked for the company, so this W2 only had this one item on it. This is another example of the US tax system baffling me with its blend of obsessive compulsive need for documentation coupled with inexplicably missing information that's critical to sensible accounting. The 1099 documents must (says the IRS since 2015) show the basis value as the award price (your discounted price).   So reading the form 8949: Note: If you checked Box D above but the basis reported to the IRS was   incorrect, enter in column (e) the basis as reported to the IRS, and   enter an adjustment in column (g) to correct the basis. We discover the number is incorrect and must adjust.  The actual value you need to adjust it by may be reported on your 1099, but also may not (I have examples of both). I calculated the required adjustment by looking at the W2, as detailed above. I gleaned this information from the following documents provided by my stock management company (you should the tax resources section of your provider): The reason people like Mint is because it allows you to see all of your financial details in one place. When you create an account, you’re able to link all of your bank accounts, credit cards, and investment accounts. This linking enables Mint to update your transactions automatically. The catch is that you have to provide the username and password you use for each one, which can certainly make you feel jittery if you’re worried about a security breach. Mint is designed to be a read-only service, which means you can’t transfer money back and forth between accounts. If someone were to get their hands on your Mint login, all they’d be able to do is view your balances and transactions. Your full account numbers aren’t displayed, nor are your bank account or credit card usernames and passwords. The only thing that would be visible would be your email address. If a hacker was interested in taking things a step further, there’s always the possibility that they could physically steal the information from Mint’s secure servers – but that’s really a long shot. That would require knowing where the servers are located, bypassing the physical security measures that are in place, and cracking the code on how the data is encrypted. If that were to happen, then your personal information might be at risk, but so far, there’s no record of it being attempted. I was very skeptical of Mint and how secure it truly was. I did my fair share of research. Try looking at: "We change it every so often to reduce fraud. This is idiocy. They receive regular payments. They are asking the people who pay them to regularly change where their money is being sent. This increases their exposure to fraud dramatically as each time the account is changed, there is a risk it will be changed to an account they do not control. This is a huge red flag. Confirm that this is authentic and, if so, insist that they sign an agreement accepting all liability for the risks this crazy policy causes, otherwise, you should refuse to go through the effort of confirming new accounts and risking typing or communication errors on a regular basis. This is definitely a ""what were they thinking?!"" kind of thing. If it's not fake entirely. (This answer assumes that you were given a correct explanation, that they change it regularly believing that will reduce fraud.)" I've had a card cloned 15 years ago and used to buy over 5k of goods in another country. So the inconvenience of having a card closed and re-issued is quite annoying even though the charges were reversed and I was made whole. But these days most CC fraud isn't from a card scanned by a waiter and cloned then used elsewhere. Mostly it is poorly secured databases or point of sale terminal malware. The latter is getting curtailed by chipped cards and the largest source of fraud is now online transactions (so called card not present) where the merchant has your CC number. If their system is breached the bad guys have a wealth of card numbers they sell in an E-bay like site on the dark web. This is where the Citi virtual CC comes in handy. Here's how it works to protect the bank and the hassles you go through when a card as to be re-issued. Citi's virtual CCs let you generate an actual credit card, complete with security code and expiration date. What is unique is that once the virtual CC is used it can only be used subsequently by that same merchant and is declined by any other. You can also set a total limit on what the merchant can charge as well as an expiration date. I use them for all my online accounts because they are, for all practical purposes, immune to the malware that steals CC info. Even if somehow the virtual CC is used before the merchant makes the initial charge that locks in the CC to their account the charge can be reversed without closing your actual card which has a different number. You can manage multiple Citi virtual CCs and view charge status, close, or adjust limits over time so managing them is quite easy with no risk to your primary account. Regardless of UK Money Laundering Laws - All companies have a responsibility under the Data Protection Act to ensure that all data kept is necessary and accurate - and so they can actually ask you to send up-to-date information* in any time period that they deem reasonable to ensure they are compliant with the act. That being said, most payment systems these days are automated and use algorithms to try and find suspicious activity. Using multiple accounts will definitely be a red flag here, unfortunately, the advice to use your previous account will just be seen as yet another account switch by these algorithms and will probably look even more suspicious. The main thing to remember is that ultimately these acts and regulations are there to protect you and your investment, so unless you have any suspicious that you're being asked for documents by a company or individual that you don't trust I would simply send them on and let them do their job. As a side note - make sure you send anything of that nature in a recorded delivery so that you know exactly who handled it and when! * So long as the information is necessary. The use of an old address would make me suspect that your data was stolen from some database you had registered to long ago with the old address.  I would think that contacting your credit rating firm and the credit card company is urgent.
