What are the tax implications on selling the Share ISA portfolio?
Assets held within an ISA or New ISA are completely free of CGT, so you won't have to pay either income tax or capital gains tax.
An order is not a transaction.  It is a request to make a transaction.  If the transaction never occurs (e.g. because you cancel the order), then no fees should be charged. will I get the stamp duty back (the 0.5% tax I paid on the shares purchase) when I sell the shares? I'm not a UK tax expert, but accorging to this page is seems like you only pay stamp tax when you buy shares, and don't get it back when you sell (but may be responsible for capital gains taxes).  That makes sense, because there's always a buyer and a seller, so if you got the tax back when you sold, the tax would effectively be transferred from the buyer to the seller, and the government would never collect anything. It is a very good idea to spread your ISAs over more than one stock broker.    However now that a lot of stock brokers charge an admin fee it can get expensive if you use too many. There is no need to tell your last year’s ISA provider that you are using a different one, however you MUST ONLY pay into one ISA provider in each tax year. According to HMRC it seems that if you overpay, then at least part of the interest generated by that ISA is taxable (emphasis mine): If, by mistake, you put more than £10,680 into your ISAs in a tax year, the excess payments are invalid, and you are not entitled to any tax relief on investments purchased with the excess payments. You should not try to correct this mistake yourself. Instead, you should call the ISA Helpline and explain the problem to them. They will advise you what action you need to take. However, as AlexMuller pointed out, HMRC also states (in section 6.1 here) that the ISA Manager (ie. the bank/building society) should not allow you to overpay. Managers’ systems must ensure that ... no more than the cash ISA subscription limit can be subscribed to a cash ISA in a tax year and that no more than the overall subscription limit can be subscribed to a stocks and shares ISA in a tax year. As to what an individual ISA Manager would do should you attempt to over-pay, I imagine it would vary from Manager to Manager. ING Direct, for example, has the following policy (Taken from Section 12.5 here): ...f you send us a payment for an amount which would take you over the ISA investment limit under the ISA Regulations, we will send the excess above the investment limit,   or, if you sent us the payment by cheque, the whole of that payment, back to you. I believe your last requirement is the main problem.  AIUI the law requires that ISA providers allow withdrawals.  They can require a notice period and they can penalise you (e.g. via lost interest) for withdrawing but they cannot prevent you accessing your money for an extended period. "I don't think blanket answers are very helpful. You are asking the right question when you are young! You have a large number of investment options and Australia has the Superannuation system that you can extract significant tax value from. I've not attempted to grade these with regard to ""risk"", as different people will rate various things with different levels, depending on their experience and knowledge. Consider the following factors for you:-" Not knowing the US laws at all, you should worry more about having the best stock portfolio and less about taxes. My 0,02€ (I'm assuming the tag of United-states is accurate) Yes, the remaining amount is tax free -- at the current price.  If you sell at exactly the original price, there is no capital gain, no capital loss.  So you've already payed the taxes. If you sell and there is a capital gain of $3000, then you will pay taxes on the $3000.  If 33% is your marginal tax rate, and if you held the stock for less than a year, then you will keep $7000 and pay taxes of $1000.  Somehow, I doubt your marginal tax rate is 33%. If you hold the stock for a year after eTrade sold some for you to pay taxes, then you will pay 15% on the gain -- or $450. eTrade sold the shares to pay the taxes generated by the income.  Yes, those shares were considered income.  If you sell and have a loss, well, life sucks.  However, if you sell something else, you can use the loss to offset the other gain.  So if you sell stock A for a loss of $3000, and sell stock B at a gain of $4000, then you pay taxes on the net of $1000. You can't actually transfer shares directly unless they were obtained as part of an employee share scheme - see the answers to questions 19 and 20 on this page: http://www.hmrc.gov.uk/isa/faqs.htm#19 Q. Can I put shares from my employee share scheme into my ISA? A. You can transfer any shares you get from into a stocks and shares component of an ISA without having to pay   Capital Gains Tax - provided your ISA manager agrees to take them. The   value of the shares at the date of transfer counts towards the annual   limit. This means you can transfer up to £11,520 worth of shares in the tax   year 2013-14 (assuming that you make no other subscriptions to ISAs,   in those years). You must transfer the shares within 90 days from the day they cease to   be subject to the Plan, or (for approved SAYE share option schemes) 90   days of the exercise of option date. Your employer should be able to   tell you more. Q. Can I put windfall or inherited shares in my ISA? A. No. You can only transfer shares you own into an ISA if they have   come from an employee share scheme. Otherwise, the ISA manager must   purchase shares on the open market. The situation is the same if you have shares that you have inherited.   You are not able to transfer them into an ISA. Good question - I know you can keep the ISA in the UK and it won't lose its tax free status but you're not able to contribute it while you're not a UK resident. Not that its tax free status buys you that much if you're a non-resident as you could apply to receive tax gross on pretty much any savings account anyway. Given that the idea of tax-free saving outside a retirement account doesn't really exist here in the US I would assume that you will have to declare the interest as income and, if you don't pay any other taxes in the UK that would cover the amount you'd have to pay on your ISA under the foreign tax credit, you'd end up giving the IRS their pound of flesh. As I mentioned in an answer to a previous question, you really need to talk to an US accountant/CPA, preferably one that is familiar with UK taxation law as well. Is selling Vested RSU is the same as selling a regular stock? Yes. Your basis (to calculate the gain) is what you've been taxed on when the RSUs vested. Check your payslips/W2 for that period, and the employer should probably have sent you detailed information about that. I'm not a US citizen, my account is in ETrade and my stocks are of a   US company, what pre arrangements I need to take to avoid tax issues? You will pay capital gains taxes on the sale in Israel. Depending on where you were when you earned the stocks and what taxes you paid then - it may open additional issues with the Israeli tax authority. Check with an Israeli tax adviser/accountant. I'm not going to tackle the 2nd part of your question, as any number of the questions tagged with international-transfer should cover you on that. There's no way to transfer an ISA into an Australian tax-free savings account, so no need to worry about anything special there. Don't forget that the FX rates change quite a bit over time, and different methods have varying fees, so moving at the wrong time could easily cost you more than the missed interest! For the first part, it depends. One thing you should seriously consider right away is switching your ISA money into one paying a better rate. Check the best-buy tables online or in a paper, as you can get a lot better than 0.1% on a transfer in, even with current depressed rates. At least that way you'll earn more interest while you decide. As for when to transfer, that's something you'll have to calculate for yourself, based on your marginal tax rate, and your view of how the FX rates will shift. If you're a 40% taxpayer, then 2% in an ISA is worth the same to you as 3.3% gross. Don't forget to consider both your UK and Australian tax rates in the year you move, as most likely you'll have to pay the higher of the two. The westpac rate looks like you might struggle to beat a decent ISA over the course of a year, were you a higher rate tax payer. Oh, and don't forget that you'll likely loose the tax-free status of your ISA once you're an Australian tax resident, so you'll need to start paying tax on interest earnt in the ISA once you're out there. If the portfolio itself is taxable, then yes; if you have two stocks and you're rebalancing them, without using new cash, you are forced to sell one stock to buy another. That sale is taxable, unless you're in some sort of tax deferred/deductible account, such as an IRA.   If you're talking about you being in a mutual fund and the fund itself rebalances, the same rules apply as above, though indirectly; you'll have capital gains realized and distributed to you, those gains will be taxed unless, again, your account is a retirement account. 1) You parents will have to pay tax on the gain as it wasn't their primary home.  You don’t pay Capital Gains Tax when you sell (or ‘dispose of’) your home if all of the following apply: As I look at it, it is your parents are the ones who own the property and they will have to pay on £60000. But as you say you pay part of the mortgage, I would go to a tax advisor/accountant to confirm if they will only pay on the £15000. I couldn't find any guidance on that matter on gov.uk 2) Inheritance tax will not be levied on it as it is below £325000, but tax will be levied on £325000, less £3000 annual gift allowance. Two articles for further information -  GOV.UK's Tax when you sell your home   Money.co.UK's Gifting money to your children: FAQs Selling one fund and buying another will incur capital gains tax on the sale for the amount of the gain. I'm not aware of any sort of exemption available due to you moving out of the country. However, long-term capital gains for low-tax-bracket taxpayers is 0%. As long as your total income including the gains fits within the 15% regular tax bracket, you don't pay any long-term capital gains. Options for you that I see to avoid taxes are: Note that even if you do sell it all, it's only the amount of gains that would take your income over the 15% normal tax bracket that would be taxed at the long-term rate of 15%, which may not end up being that much of a tax hit. It may be worth calculating just how bad it would be based on your actual income. Also note that all I'm saying here is for US federal income taxes. The state you most recently lived in may still charge taxes if you're still considered a resident there in some fashion, and I don't know if your new home's government may try to take a cut as well. The mathematical answer is for you to have a diversified portfolio in your ISA.  But that's easier said than done.
