Is the interest on money borrowed on margin in/for an RRSP considered tax deductible?
I believe your question is based on a false premise. First, no broker, that I know of, provides an RRSP account that is a margin account. RRSP accounts follow cash settlement rules.  If you don't have the cash available, you can't buy a stock.  You can't borrow money from your broker within your RRSP. If you want to borrow money to invest in your RRSP, you must borrow outside from another source, and make a contribution to your RRSP.  And, if you do this, the loan interest is not considered tax deductible. In order for investment loan interest to be tax deductible, you'd need to invest outside of a registered type of account, e.g. using a regular non-tax-sheltered account. Even then, what you can deduct may be limited. Refer to CRA - Line 221 - Carrying charges and interest expenses: You can claim the following carrying charges and interest [...] [...]   You cannot deduct on line 221 any of the following amounts:
(a) you give away your money - gift tax The person who receives the gift doesn't owe any tax.  If you give it out in small amounts, there will be no gift tax. It could have tax and Estate issues for you depending on the size of the gift, the timing, and how much you give away in total.  Of course if you give it away to a charity you could deduct the gift. (b) you loan someone some money - tax free?? It there is a loan, and and you collect interest; you will have to declare that interest as income. The IRS will expect that you charge a reasonable rate, otherwise the interest could be considered a gift. Not sure what a reasonable rate is with savings account earning 0.1% per year. (c) you pay back the debt you owe - tax free ?? tax deductible ?? The borrower can't deduct the interest they pay, unless it is a mortgage on the main home, or a business loan. I will admit that there may be a few other narrow categories of loans that would make it deductible for the borrower. If the loan/gift is for the down payment on a house, the lender for the rest of the mortgage will want to make sure that the gift/loan nature is correctly documented. The need to fully understand the obligations of the homeowner. If it is a loan between family members the IRS may want to see the paperwork surrounding a loan, to make sure it isn't really a gift. They don't look kindly on loans that are never paid back and no interest collected. Most brokers have a margin maintenance requirement of 30%.  In your example, it would depend on how much money you're borrowing from your broker on margin. Consider this: You have $250, and short AAPL at $500 on margin. This would be a common scenario (federal law requires investors to have at least 50% of their margin equity when opening a transaction). If your broker had a requirement of 30%, they would require that for your $500 position, you have at least $500 * .3 = $150 equity. Since you are currently above that number at $250, you will not be hit with a margin call. Say the price of AAPL doubles, and now your position is worth $1000. $1000 * .3 = $300, which is $50 above your initial equity. Your broker will now consider you eligible for a margin call. Most will not execute the call right away, you will often have some time to either sell/cover stock or add funds to your account. But not all brokers will warn you if you are breaking margin requirements, and sometimes margin calls can take you by surprise if you are not paying attention. Also, many will charge interest on extra margin borrowed. "For an RRSP, you do not have to pay taxes on money or investments until you withdraw the money. If you do not reinvest the dividends but instead, take them out as cash, that would be withdrawing the money. For mutual funds, you would normally reinvest the dividends if holding the investment inside an RRSP. For stocks, I believe the dividends would end up sitting in the cash part of your RRSP account (and you'd probably use the money to buy more stocks, though would not be required to do so). Either way, you do not pay tax on this investment income unless you withdraw it from your RRSP. For example, you invest $10,000 inside your RRSP. You get the tax benefit from doing so. You get dividends of $1,000 (hey, it was a good year), and use these to buy more stock. As the money never left your RRSP account, you are considered to have invested only your initial $10,000. If instead, you withdraw the $1,000 in dividends, you are taxed on $1000 income. TFSA are slightly more complicated. You don't get a tax benefit from your initial contribution, but then do not pay tax when you withdraw from the TFSA. Your investment income is still tax-free, and you are (generally) much more limited in how much you can contribute. For example, you invest $10,000 inside your TFSA. You get dividends of $1,000, and use these to buy more stock. Your total contributions to your TFSA remains at $10,000 as the money never left your account. You could instead withdraw the $1000 from your TFSA and would not pay tax on it. In the next calendar year (or later) after the withdrawal, you could ""repay"" the $1000 you took out without suffering an overcontribution penalty. This makes TFSA an excellent place to park emergency funds, as you can withdraw and subsequently replace the investment while continuing to get the tax benefits on your investment income. RRSPs are better for retirement or for the home buyers plan. In general, you should not be withdrawing money from either your TFSA or RRSP, except in emergencies, when retiring, or when purchasing a home. I prefer indexed mutual funds or money market accounts for both my RRSP and TFSA rather than individual stocks, but that's up to you." "Mortgage interest in Canada is not generally tax deductible for individuals. (Where did you read otherwise?) As an individual, the only mortgage interest you may be able to deduct is when you borrow the money to purchase an income-producing asset, e.g another property you can rent out, or investments producing dividends or other income.  In these cases, the interest you pay on the borrowed funds, i.e. the ""carrying costs"" for your investments, would be deductible against the income produced by the investments purchased." It doesn't make much difference in the end. Imagine you have $100 of revenue in your company. You can either pay it to yourself as salary, meaning that you don't pay corporate tax on it, or you can keep it in the company, pay corporate tax on it, then pay yourself a dividend of what is left. While that dividend will be treated better than salary, remember that the company already paid tax on it. You paying less on what's left doesn't equate to paying less overall. Go ahead and run the numbers using your actual corporate tax rate and your personal income tax rate. Try doing your whole salary as dividends - not dollar for dollar, but as how much the company would have as profit to give you a dividend if it didn't spend (and deduct) salary money on you. You are unlikely to see any difference at all. The net final money in your pocket, and the amount that went to the government, will probably be the same. If paying dividends keeps your earned income low, you may find that you can't use RRSP or childcare deductions. You are also not getting CPP credit. That's an argument for salary, or at least a certain minimum amount of salary. You have to deduct taxes at source on salary and send it along to the government, which is an argument for dividends if you feel you could invest that money and use it well before the taxes get around to being due. Possibly you may discover an edge case where you move a few thousand from one marginal tax rate to another and clear a few hundred extra as a result. I don't discourage you from doing the math, I just point out that the various percentages (tax rates, grossups, deductions etc) have all been carefully chosen so that it pretty much works out the same, or gives a small preference to salary. We give excess money to ourselves as bonus rather than dividend having run the numbers a few times. There's no secret trick here. Eeeeeeh... No, you don't. In Canada, and pretty much any country with common sense they will rarely charge you for income made outside its borders. In the worst case scenario you're taxed on income deemed resulting from investment (stocks, bonds, etc.), but the general rule is... You don't pay taxes on income made abroad. My wife and I are both Canadian citizens living in the US with green card status.  I still have a Canadian RRSP and bank account in Canada that are dormant for the most part.  We use the Canadian debit card only when traveling (which is quite helpful). Neither of us file any paperwork in Canada anymore.  But as others have mentioned, we do file the FBAR form... this takes about 10 minutes and gets mailed somewhere in Michigan if I recall correctly.  (Keep the balance less than $10k total among all foreign accounts and you relieve yourself of this too.) As far as taxes go, we make less interest in our Canadian account than in our US accounts, so the tax burden is less. That Economist quote only offers a very weak argument.  It doesn't argue from anything fundemental, it just says they think corporations borrow too much and the tax-code should remove this insentive to borrow.  That's an arguement based on a feeling and weak.   There's absolutely a logical consistency to allow a deduction for interest at the corporate level and not dividends.  As mentioned, interest is an expense to a financier, dividends are distributed residual income.
