Do I have to pay tax on money I earn as a tutor?
You would be required to report it as self-employment income and pay tax accordingly.  It's up to you to keep proper records (like a receipt book, for example), especially when it comes to cash.  If you can't prove exactly how much you earned and the government decides to guess the amount for you then you won't like the outcome! There is a moral and legal obligation to file the earnings. Not doing so is tax fraud. You should keep a ledger or some record of your earnings, helpful guidelines here. Records are required by the CRA: According to the law, your responsibilities include: (source) You could get in trouble if one of your pupils report the expense at their tax filing, and the CRA finds no matching statement on your filing report. Tutoring are eligible for tax credit in case of disability: Tutoring services that are supplementary to the primary education of a person with a learning disability or an impairment in mental functions, and paid to a person in the business of providing these services to individuals who are not related to the person. A medical practitioner must certify in writing that these services are necessary. So if one of your pupils fall under that provision, you will get tax trouble sooner or later. Bottom line: start making records now, and report your earnings. Collect your tax as any lawful citizen is required to.
"TL;DR - my understanding of the rules is that if you are required to register for GST (earning more than $75k per annum), you would be required to pay GST on these items. To clarify firstly: taxable income, and goods and services tax, are two different things. Any income you receive needs to be considered for income tax purposes - whether or not it ends up being taxable income would be too much to go into here, but generally you would take your expenses, and any deductions, away from your income to arrive at what would generally be the taxable amount. An accountant will help you do this. Income tax is paid by anyone who earns income over the tax free threshold. By contrast, goods and services tax is a tax paid by business (of which you are running one). Of course, this is passed on to the consumer, but it's the business that remits the payment to the tax office. However, GST isn't required to be charged and paid in all cases: The key in your situation is first determining whether you need to register for GST (or whether indeed you already have). If you earn less than $75,000 per year - no need to register. If you do earn more than that through your business, or you have registered anyway, then the next question is whether your items are GST-free. The ATO says that ""some education courses [and] course materials"" are GST-free. Whether this applies to you or not I'm obviously not going to be able to comment on, so I would advise getting an accountant's advice on this (or at the very least, call the ATO or browse their legal database). Thirdly, are your sales connected with Australia? The ATO says that ""A sale of something other than goods or property is connected with Australia if ... the thing is done in Australia [or] the seller makes the sale through a business they carry on in Australia"". Both of these appear to be true in your case. So in summary: if you are required to register for GST, you would be required to pay GST on these items. I am not a financial advisor or a tax accountant and this is not financial advice." You only need to report INCOME to the IRS. Money which you are paying to a landlord on behalf of someone else is not income. 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. House rent allowance:7500 House Rent can be tax free to the extent [less of] Medical allowance : 800 Can be tax free, if you provide medical bills. Conveyance Allowance : 1250 Is tax free.  Apart from this, if you invest in any of the tax saving instruments, i.e. Specified Fixed Deposits, NSC, PPF, EPF, Tution Fees, ELSS, Home Loan Principal etc, you can get upto Rs 150,000 deductions. Additional Rs 50,000 if you invest into NPS. If you have a home loan, upto Rs 200,000 in interest can be deducted. So essentially if you invest rightly you need not pay any tax on the current salary, apart from the Rs 200 professional tax deducted. Generally, prize money is miscellaneous income, reported on line 21 of your 1040 and not subject to self employment tax. See IRS publication 525 for more details; under 'Prizes and Awards', they give an example of winning a photography contest. Now, there are a couple of exceptions. If your main occupation is participating in contests such as this - or you do it sufficiently that it could be considered such - then it may be considered something you should pay self employment taxes on. If it's your first one - you're fine. Also, it would have to be something that doesn't look like work for me to be confident it's self employment income. I'm not sure that winning the Netflix prize for improving on their algorithm by 10% wouldn't run the risk of being considered sort of employment. I'm not a tax advisor, but in that case I would hire one to be sure.  I could imagine companies abusing 'prizes' otherwise to get out of paying employment taxes... "If a country had a genuine completely flat income tax system, then it wouldn't matter who paid the tax since it doesn't depend on the employee's other income. Since not many countries run this, it doesn't really make sense for the employee to ""take the burden"" of the tax, as opposed to merely doing the administration and paying the (probable) amount of tax at payroll, leaving the employee to use their personal tax calculation to correct the payment if necessary. Your prospective employer is probably saying that your tax calculation in Singapore is so simple they can do it for you. They may or may not need to know a lot of information about you in order to do this calculation, depending what the Singapore tax authorities say. If you're not a Singapore national, they may or may not be relying on bilateral tax agreements with your country to assert that you won't have to pay any further tax on the income in your own country. It's possible they're merely asserting that you won't owe anything else in Singapore, and in fact you will have taxes to report (even if it's just reporting to your home tax authority that you've already paid the tax). Still, for a foreign worker a guarantee you won't have to deal with the local tax authority is a good thing to have even if that's all it is. Since there doesn't appear to be any specific allowance for ""tax free money"" in the Singapore tax system, it looks like what you have here is ""just"" the employer agreeing to do something that will normally result in the correct tax being paid in your behalf. This isn't uncommon, but it's also not exactly what you asked for. And in particular if you have two jobs in Singapore then they can't both be doing this, since tax is not flat. The example calculation includes varying tax rates for the first X amount of income that (I assume without checking) are per person, not per employment. Joe's answer has the link. In practice in the UK (for example), there are plenty of UK nationals working in the UK who don't need to do a full tax return and whose tax is collected entirely at source (between PAYE and deductions on bank interest and suchlike). In this sense the employer is required by law to take the responsibility for doing the admin and making the tax payments to HMRC. Note that a UK employer doesn't need to know your circumstances in detail to make the correct payroll deductions: all they need is a so-called ""tax code"", which is calculated by HMRC and communicated to the employer, and which basically encodes how much they can pay you at zero rate before the various tax rate tiers kick in. That's all the employer needs to know here for the typical employee: they don't need to know precisely what credits and liabilities resulted in the figure. However, these employers still don't offer empoyees a net salary (that is, they don't take on the tax burden), because different employees will have different tax codes, which the employer would in effect be cancelling out by offering to pay two people the same net salary regardless of their individual circumstances. The indications seem to be that the same applies in Singapore: this offer is really a net salary subject to certain assumptions (the main one being that you have no other tax liabilities in Singapore). If you're a Singapore millionaire taking that job for fun, you might find that the employer doesn't/can't take on your non-standard tax liability on this marginal income." I know that if you make more, you pay more, but do those who have   more, not make more, pay higher income tax? In general, no. In most locales, income tax is based on income, not on wealth. I am retired. I have little income but a fair amount of wealth. I play very little income tax. (But I do pay other kinds of taxes.) Here's a scenario. 2 people of average wealth with similar situations   have the same job with equal pay. After 5 years, their situations   haven't changed and they still earn equal pay, but now one has $40,000   in their account and the other $9,000. Does one now pay higher income   tax because he has more in his account or does he pay the same because   he makes the same? In most locales, you pay income tax on everything that is counted as income. Your salary is income. In some cases, earned interest is income.  But aside from the earned interest from your bank accounts, neither the $40,000 nor the $9,000 is income. Your huge mansion isn't income. Your expensive car isn't income. The huge amount of land you own isn't income. The pricey artwork on your walls isn't income. You don't pay income tax on any of these, but your local may impose other taxes on these (such as property tax, etc.) [Note: consult the tax laws of your specific locale if you want to know details.] Pennsylvania is one of the states that divide the land up in to thousands of jurisdictions all of which have the power to tax.  Where you live (or work) is located in either a county, city, township or borough. They can tax you based on either your income, your property. You can also be taxed by the school district which can encompass multiple jurisdictions. You should get local tax help to make sure that all the appropriate taxes are being covered. Since you have already paid tax to the Government of Uk, no tax will be levied on the money earned outside India. As per the Income tax act, any income received in India in all cases is taxable irrespective of the tax payer's residential status. A NRI after receiving income from outside India cannot be taxed as income because of remittance of such income to India. "What theyre fishing for is whether the money was earned in the U.S.  It's essentially an interest shelter, and/or avoiding double taxation.   They're saying if you keep income you make outside the US in a bank inside the US, the US thanks you for storing your foreign money here and doesn't tax the interest (but the nation where you earned that income might).   There is no question that the AirBNB income is ""connected with a US trade or business"".   So your next question is whether the fraction of interest earned from that income can be broken out, or whether IRS requires you to declare all the interest from that account.   Honestly given the amount of tax at stake, it may not be worth your time researching.   Now since you seem to be a resident nonresident alien, it seems apparent that whatever economic value you are creating to earn your salary, is being performed in the United States. If this is for an American company and wages paid in USD, no question, that's a US trade or business. But what if it's for a Swedish company running on Swedish servers, serving Swedes and paid in Kroner to a Swedish bank which you then transfer to your US bank? Does it matter if your boots are on sovereign US soil?  This is a complex question, and some countries (UK) say ""if your boots are in our nation, it is trade/income in our nation""... Others (CA) do not.  This is probably a separate question to search or ask. To be clear, the fact that your days as a teacher or trainee do not count toward residency, is a separate question from whether your salary as same counts as US income." It's income. It's almost certainly subject to income tax. As miscellaneous income, if nothing else. (That's what hobby income usually falls under.) If you kept careful records of the cost of developing the app, you might be able to offset those against the income... again, as with hobby income. Do you get cash (or a deposit into your bank account) of your PhD stipend and then you immediately send the university a check to pay the tuition fee (which might be more than the cash you get from the University)? Or does the University simply keep the stipend money, transferring it from one pocket to another in essence, and say, OK, you have paid your tuition except for $X that you still owe us? Or does the university grant you a tuition waiver as part of your assistantship and reports this as income on Form 1099-MISC? In all of these cases, the money reported on Form 1099-MISC is not taxable income to you, and it is neither subject to Self-Employment tax (basically, Social Security and Medicare tax -- both the employee's share and the employer's share) nor to (Federal) income tax. "In the UK it all comes down to what HMRC will allow you to charge without taxing you on the ""rent profit"" and not hitting capital gain tax when you sell the house, it may not all count as your ""main home"" if some is rented out.   (http://www.accountingweb.co.uk/ is a good place to ask this type of questions in the uk)" Tax is due in India as you offered services from India.  So whether the International Client pays via Credit Card, Bank Transfer, Paypal or any other means is not relevant. Even if the International Client pays you in a account outside India; it is still taxable in India. "As you are earning an income by working in India, you are required to pay tax in India. If you contract is of freelance, then the income earned by you has to be self declared and taxes paid accordingly. There are some expenses one can claim, a CA should be able to guide you.
