Austrailian tax resident earning salary in the UK - how much tax do I pay on foreign income?
This page and this page on the ATO website provide some information on tax rates. They're rather lengthy and there's a few exceptions, but essentially, your entire foreign income, even if held overseas, is taxable. Australians are taxed worldwide.
Note:  This is not professional tax advice.  If you think you need professional tax advice, find a licensed professional in your local area. What are the expected earnings/year? US$100? US$1,000?  US$100,000?  I would say if this is for US$1,000 or less that registering an EIN, and consulting a CPA to file a Partnership Tax return is not going to be a profitable exercise.... all the earnings, perhaps more, will go to paying someone to do (or help do) the tax filings. The simplest taxes are for a business that you completely own.  Corporations and Partnerships involve additional forms and get more and more and complex, and even more so when it involves foreign participation.  Partnerships are often not formal partnerships but can be more easily thought of as independent businesses that each participants owns, that are simply doing some business with each other. Schedule C is the IRS form you fill out for any businesses that you own. On schedule C you would list the income from advertising.  Also on schedule C there is a place for all of the business expenses, such as ads that you buy, a server that you rent, supplies, employees, and independent contractors.  Amounts paid to an independent contractor certainly need not be based on hours, but could be a fixed fee, or based on profit earned.   Finally, if you pay anyone in the USA over a certain amount, you have to tell the IRS about that with a Form 1099 at the beginning of the next year, so they can fill out their taxes.  BUT.... according to an article in International Tax Blog you might not have to file Form 1099 with the IRS for foreign contractors if they are not US persons (not a US citizen or a resident visa holder). "Can I use the foreign earned income exclusion in my situation? Only partially, since the days you spent in the US should be excluded. You'll have to prorate your exclusion limit, and only apply it to the income earned while not in the US. If not, how should I go about this to avoid being doubly taxed for   2014? The amounts you cannot exclude are taxable in the US, and you can use a portion of your Norwegian tax to offset the US tax liability. Use form 1116 for that. Form 1116 with form 2555 on the same return will require some arithmetic exercises, but there are worksheets for that in the instructions. In addition, US-Norwegian treaty may come into play, so check that out. It may help you reduce the tax liability in the US or claim credit on the US taxes in Norway. It seems that Norway has a bilateral tax treaty with the US, that, if   I'm reading it correctly, seems to indicate that ""visiting researchers   to universities"" (which really seems like I would qualify as) should   not be taxed by either country for the duration of their stay. The relevant portion of the treaty is Article 16. Article 16(2)(b) allows you $5000 exemption for up to a year stay in the US for your salary from the Norwegian school. You will still be taxed in Norway. To claim the treaty benefit you need to attach form 8833 to your tax return, and deduct the appropriate amount on line 21 of your form 1040. However, since you're a US citizen, that article doesn't apply to you (See the ""savings clause"" in the Article 22). I didn't even give a thought to state taxes; those should only apply   to income sourced from the state I lived in, right (AKA $0)? I don't know what State you were in, so hard to say, but yes - the State you were in is the one to tax you. Note that the tax treaty between Norway and the US is between Norway and the Federal government, and doesn't apply to States. So the income you earned while in the US will be taxable by the State you were at, and you'll need to file a ""non-resident"" return there (if that State has income taxes - not all do)." "I also don't know the specific details for Finland and/or Belgium, however many countries have tax treaties, which generally prevent double taxation (i.e., paying tax in both countries on the same base income). Being that both Finland and Belgium are EU member states, I'm quite certain there's a provision that covers this, and the same would apply: You pay taxes on what you earn while in Finland to Finland, and to Belgium what you earn while in Belgium. All of this is similar to what you presented, however there's also a section where you'd declare how much taxes were paid in other countries. One other thing to note, which will be the determining factor in the above, is whether EU law requires you to change residence to BE for the time you're there. If not  then you'll be paying taxes in Finland the entire time on the entire amount. This comes from an Irish governmental site: ""By working in another member state and by transferring your residence there, you are likely to become ""resident for tax purposes"" there. The definition of fiscal residence varies from one member state to another. You must comply with the laws of the country where you have established your residence. The laws on personal taxation vary considerably from one member state to another and you may be liable for taxation in more than one country. In general, you are subject to income tax in the country where you are living but this may not be the case if you are a “posted worker” – see below. In general, property is taxed in the country in which it is situated but, again, there are variations. Tax agreements have been concluded between most of the member states of the EU, which are intended to avoid double taxation, if you derive income from different countries. In general, national fiscal rules must respect the fundamental principle of non-discrimination against nationals of another EU country.""" "First of all congrats... very nice work indeed..  Secondly, i do not offer this as legal advise.. lol.. anyhow.. you need to make sure to hang on to as much as possible, being a single earner, our Uncle (Sam) is going to want what's due... That being said, you should probably look into investments, for starters, purchase a primary residence or start a business, or purchase a primary residence and use that as a business residence (both).. what you basically want are write-offs.. you need to bring your ""taxable"" income as low as possible so you pay minimal taxes.. in your case, you're in danger of paying a hefty sum in taxes... i'm sure you can shield yourself with various business expenses (a car, workplace, computers, etc.. ) that you could benefit from, both professionally and individually.. and then seriously bro... making 250k leads me to believe you've got at least more than half a brain, and that you're using more than half of that.. so dude.. get an accountant... and one you can trust.. ask your parents, colleagues, people you've worked with in the past.. etc.. there are professionals who are equally as talented in helping you keep your money as you are in making it.. -OR- you could get married, make sure your wife stays at home and start popping out kids asap... those keep my taxable (and excess) income pretty low.. LOL!!! I'm going to add to this... as a contractor, i've generally put any ""estimated"" taxes into some kind of interest accruing account so i can at least make a little money before i have to give it away.. in your case, i'd say put away at least 2/3's into some kind of interest earning account.. start by talking to your personal banker wherever your money is.. you'll be surprised at how nice they treat you... you ARE going to have to pay taxes.. so until you do, try to make a little money while it sits..  again, nice problem to have!" For income tax, you can expect to pay (see here for the rates): For class 4 NICs, it should be (see here for the rates): So expected take-home is £36667. You can avoid the income tax - but not the NICs - by putting money into a pension. For example you might put £7525 in to eliminate the entire 40% part of the bill, which would only cost you £4515 from your take-home pay because it would reduce the tax bill by the £3010. 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. In the UK you have an allowance of £40,000 per annum for tax relief into a pension. This amount includes both your and your employer's contributions. If you earn more than £150,000 per annum this allowance starts to reduce and if you earn less than the allowance, your allowance is limited to what you earn. You can also carry over unused allowance from up to 3 years previously. If you stick within this allowance you won't pay tax on your pension contributions, if you go over the excess will be subject to tax. Salary exchange normally lets you avoid the National Insurance value of your contribution being taxed. If you paid your own money into your pension (without going through salary exchange), your contributions would have the 20% basic rate of tax credited to them and if you're a higher rate taxpayer you could reclaim the difference between the basic rate of tax and the higher rate of tax you pay but the National Insurance you've paid on your own money would not be reclaimable. You can't get the money back you've paid into your pension till you are are 58 (given that you are 27 now), the minimum age has risen from its historic 55 for your age group.  That's the pension trade off, you forgo tax now in the expectation that, once retired, you will be paying tax at a lower rate (because your income will be lower and you are much less likely to be subject to higher rate taxation) in return for locking in your money till you're older. Your pension income will be subject to tax when you eventually take it. There are other options such as ISAs which have lower annual limits (£20,000 currently) and on which your contributions do not attract tax relief, but which are not taxed as income when you eventually spend them. ISAs and pensions are not mutually exclusive so if you have the money, you can do both. It's up to you to determine what mix of savings will be appropriate to generate income for your eventual retirement. If you are living in some other country when you retire your pension will be paid net of UK tax. You might then be able to claim (or pay) any difference between that and your local tax rate depending on what agreement exists between the UK government and the other country's government. You will have to pay your taxes in the UK not USA. For tax purposes it is the company's tax residency not where the server is located. You are just hiring a server in USA. Take for example a CDN being used for your same service then would you pay taxes in 300 different countries if you use Akamai? Does not work that way.
