Can I deduct equipment expenses for a job I began overseas?
A computer is a special case because the IRS thinks that you might be using it for personal applications.    You may need to keep a log, or be able to state that you also have another computer for non-business use. That said, if your schedule C shows a small profit then you don't need to itemize expenses, just state the total. I'm not an expert, but here's my $0.02. Deductions for business expenses are subject to the 2% rule. In other words, you can only deduct that which exceeds 2% of your AGI (Adjusted Gross Income). For example, say you have an AGI of $50,000, and you buy a laptop that costs $800. You won't get a write-off from that, because 2% of $50,000 is $1,000, and you can only deduct business-related expenses in excess of that $1,000. If you have an AGI of $50,000 and buy a $2,000 laptop, you can deduct a maximum of $1,000 ($2,000 minus 2% of $50,000 is $2,000 - $1,000 = $1,000). Additionally, you can write off the laptop only to the extent that you use it for business. So in other words, if you have an AGI of $50,000 and buy that $2,000 laptop, but only use it 50% for business, you can only write off $500. Theoretically, they can ask for verification of the business use of your laptop. A log or a diary would be what I would provide, but I'm not an IRS agent.
I looked at Publication 463 (2014), Travel, Entertainment, Gift, and Car Expenses  for examples. I thought this was the mot relevant. No regular place of work.   If you have no regular place of work but   ordinarily work in the metropolitan area where you live, you can   deduct daily transportation costs between home and a temporary work   site outside that metropolitan area. Generally, a metropolitan area includes the area within the city   limits and the suburbs that are considered part of that metropolitan   area. You cannot deduct daily transportation costs between your home and   temporary work sites within your metropolitan area. These are   nondeductible commuting expenses. This only deals with transportation to and from the temporary work site.  Transportation expenses do not include expenses you have while   traveling away from home overnight. Those expenses are travel expenses   discussed in chapter 1 . However, if you use your car while traveling   away from home overnight, use the rules in this chapter to figure your   car expense deduction. See Car Expenses , later. You will also have to consider the cost of tolls of the use of a  trailer if those apply. First of all, Dilip's answer explains well how the business deductions generally work. For most (big) expenses you depreciate it. However, in some cases you need to capitalize it, which is another accounting method. When you capitalize your expense, it becomes part of the basis of the product you're creating. Since you're an engineer, this might be relevant for you. Talk to your tax adviser. How exactly you deduct/depreciate/capitalize things, and what expense goes which way depends greatly on the laws and jurisdictions. Even in the US, different states have different laws, and the IRS and State laws don't have to conform (unfortunately). For example, the limitations on Sec. 179 deduction in 2010-2011 were 20 times higher on Federal level than in the State of California. This could have lead to cases where you fully deducted your expense on your Federal tax return, but need to continue and depreciate it on your State return (or vice versa). Good tax adviser is crucial to avoid or manage these cases. Depending on what software you use. It has to be reported as a foreign income and you can claim foreign tax paid as a foreign tax credit. "To be deductible, a business expense must be both ordinary and necessary. An ordinary expense is one that is common and accepted in your trade or business. A necessary expense is one that is helpful and appropriate for your trade or business. An expense does not have to be indispensable to be considered necessary.  (IRS, Deducting Business Expenses) It seems to me you'd have a hard time convincing an auditor that this is the case.  Since business don't commonly own cars for the sole purpose of housing $25 computers, you'd have trouble with the ""ordinary"" test.  And since there are lots of other ways to house a computer other than a car, ""necessary"" seems problematic also." "Hobby expenses are not tax deductible.  Business expenses are, but only if it's a bona fide business.  First they look at profitability: if you reported a net profit (i.e. paid taxes) in your first 3 years, they will believe you rant on Youtube for a living.   Remember, by the time they get around to auditing you, you'll likely be well into, or through, your third year.   There is an exception for farms.  Other than that, if you lose money year after year, you better be able to show that you look, walk and quack like a business; and one with a reasonable business reason for delayed profitability.  For instance Netflix's old business model of mailing DVDs had very high fixed infrastructure expense that took years to turn profitable, but was a very sensible model.  They're fine with that.  Pets.com swandived into oblivion but they earnestly tried. They're fine with that too.  You can't mix all your activities. If you're an electrician specializing in IoT and smart homes, can you deduct a trip to the CES trade show, you bet.  Blackhat conference, arguable.  SES?  No way.  Now if you had a second business of a product-reco site which profited by ads and affiliate links, then SES would be fine to deduct from that business.  But if this second business loses money every year, it's a hobby and not deductible at all.  That person would want separate accounting books for the electrician and webmaster businesses.  That's a basic ""duck test"" of a business vs. a hobby. You need to be able to show how each business gets income and pays expense separate from every other business and your personal life.  It's a best-practice to give each business a separate checking account and checkbook. You don't need to risk tax penalties on a business-larva that may never pupate.  You can amend your taxes up to 3 years after the proper filing date.  I save my expense reciepts for each tax year, and if a business becomes justifiable, I go back and amend past years' tax forms, taking those deductions.  IRS gives me a refund check, with interest!" I will not pay any taxes in the Us, since I am not working for an US   company What you will or will not pay is up to you of course, but you definitely should pay taxes in the US, as you're working in the US. Since you mentioned being from Japan, I'll also suggest checking whether you're allowed to perform any work in the US under the conditions of your visa. If you're a F1/J1 student - you'll be breaking the immigration law and may be deported. You might be liable for taxes in Germany, as well, and also in Japan. I'll have to edit this to allow people who downvoted the answer without knowing the legal requirements to change their vote. F1 student cannot be a contractor without a valid EAD. Period. There's no doubt about it and legal requirements are pretty clear. Anyone who claims that you wouldn't be breaking the terms of your visa is wrong. Note, I'm neither a lawyer nor a tax professional, for definite advice talk to a professional. The IRS Guidance pertaining to the subject.  In general the best I can say is your business expense may be deductible.  But it depends on the circumstances and what it is you want to deduct. Travel Taxpayers who travel away from home on business may deduct related   expenses, including the cost of reaching their destination, the cost   of lodging and meals and other ordinary and necessary expenses.   Taxpayers are considered “traveling away from home” if their duties   require them to be away from home substantially longer than an   ordinary day’s work and they need to sleep or rest to meet the demands   of their work. The actual cost of meals and incidental expenses may be   deducted or the taxpayer may use a standard meal allowance and reduced   record keeping requirements. Regardless of the method used, meal   deductions are generally limited to 50 percent as stated earlier.    Only actual costs for lodging may be claimed as an expense and   receipts must be kept for documentation. Expenses must be reasonable   and appropriate; deductions for extravagant expenses are not   allowable. More information is available in Publication 463, Travel,   Entertainment, Gift, and Car Expenses. Entertainment Expenses for entertaining clients, customers or employees may be   deducted if they are both ordinary and necessary and meet one of the   following tests: Directly-related test: The main purpose of the entertainment activity is the conduct of business, business was actually conducted   during the activity and the taxpayer had more than a general   expectation of getting income or some other specific business benefit   at some future time.   Associated test: The entertainment was associated with the active conduct of the taxpayer’s trade or business and occurred directly   before or after a substantial business discussion. Publication 463 provides more extensive explanation of these tests as   well as other limitations and requirements for deducting entertainment   expenses. Gifts Taxpayers may deduct some or all of the cost of gifts given in the   course of their trade or business. In general, the deduction is   limited to $25 for gifts given directly or indirectly to any one   person during the tax year. More discussion of the rules and   limitations can be found in Publication 463. If your LLC reimburses you for expenses outside of this guidance it should be treated as Income for tax purposes. Edit for Meal Expenses: Amount of standard meal allowance.   The standard meal allowance is   the federal M&IE rate. For travel in 2010, the rate for most small   localities in the United States is $46 a day. Source IRS P463 Alternately you could reimburse at a per diem rate A non-resident alien is only allowed for deductions connected to producing a US-sourced income (See IRC Sec. 873). Thus you can only deduct things that qualify as business expenses, and State taxes on your wages. In addition you can deduct a bunch of stuff explicitly allowed (like tax preparation, charitable contributions, casualty losses, etc) but sales tax is not in that list. No, you cannot. You can only deduct expenses that the employer required from you, are used solely for the employer's (not your!) benefit, you were not reimbursed for them and they're above the 2% AGI threshold. And that - only if you're itemizing your deductions. "As a person who has had several part time assistants in the past I will offer you a simple piece of advise that should apply regardless of what country the assistant is located. If you have an assistant, personal or business, virtual or otherwise, and you don't trust that person with this type of information, get a different assistant.  An assistant is someone who is supposed to make your life easier by off loading work. Modifying your records before sending them every month sounds like you are creating more work for yourself not less. Either take the leap of faith to trust your assistant or go somewhere else.  An assistant that you feel you have to edit crucial information from is less than useful. That being said, there is no fundamental reason to believe that an operation in the Philippines or anywhere else is any more or less trustworthy than an operation in your native country. However, what is at issue is the legal framework around your relationship and in particular your recourse if something goes wrong.  If you and your virtual assistant are both located in the US you would have an easier time collecting damages should something go wrong.  I suggest you evaluate your level of comfort for risk vs. cost.  If you feel that the risk is too high to use an overseas service versus the savings, then find someone in the states to do this work.  Depending on your needs and comfort you might want to seek out a CPA or other licensed/bonded professional.  Yes the cost might be higher however you might find that it is worth it for your own piece of mind. As a side note you might even consider finding a local part-time assistant. This can often be more useful than a virtual assistant and may not cost as much as you think. If you can live without someone being bonded.  (or are willing to pay for the bonding fee) yourself,  depending on your market and needs you may be able to find an existing highly qualified EA or other person that wants some after hours work.   If you are in a college town, finance, accounting or legal majors make great assistants.  They will usually work a couple hours a week for ""beer money"", they have flexible schedules and are glad to have something pertinent to their degree to put on their resume when they graduate.  Just be prepared to replace them every few years as they move on to real jobs." This answer is assuming you're in the US, which apparently you're not. I doubt that the rules in the EU are significantly different, but I don't know for sure. In case of an IRS control, is it ok to say that I regularly connect   remotely to work from home although in the work contract it says I   must work at client's office? No. Are there any other ways I can prove that this deduction is valid? No. You can't prove something is valid when its not. You can only deduct home office expense if it is used exclusively for your business, and your bedroom obviously is not. Business Apprentice is internship. That is not what is applicable for you. You're a visiting professor/researcher, which falls under Article 22, so you don't get the standard deduction. First, you should probably have a proper consultation with a licensed tax adviser (EA/CPA licensed in your State). In fact you should have had it before you started, but that ship has sailed. You're talking about start-up expenses. You can generally deduct up to $5000 in the year your business starts, and the expenses in excess will be amortized over 180 months (15 years). This is per the IRC Sec. 195. The amortization starts when your business is active (i.e.: you can buy the property, but not actually open the restaurant - you cannot start the depreciation). I have a couple questions about accounting - should all the money I   spent be a part of capital spending? Or is it just a part of it? If it qualifies as start-up/organizational expenses - it should be capitalized. If it is spent on capital assets - then it should also be capitalized, but for different reasons and differently. For example, costs of filing paperwork for permits is a start-up expense. Buying a commercial oven is a capital asset purchase which should be depreciated separately, as buying the tables and silverware. If it is a salary expense to your employees - then it is a current expense and shouldn't be capitalized. Our company is LLC if this matters.  It matters to how it affects your personal tax return. "It depends on what the ""true"" reason for the trip is.  If you decide to deduct the trip as a business expense, then during an audit you will be asked why you had to go there. If there was nothing accomplished via the travel (that is, you worked from the hotel, met with no clients, visited no tradeshows, etc) then the expense is unlikely to be allowed. Yes, on a business trip you can do sightseeing if you wish (though you can't deduct any sightseeing specific expenses, like admission to a tourist attraction), but if you are just working while on vacation, then the trip itself is not deductible, since there was no business benefit to traveling in the first place." "The answer is ""Yes"", You can deduct them. As long as you showed that you put in effort to make a profit then you can deduct business expenses."
