Can I deduct taxes for home office as a freelance computer software developer?
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. You can do it, provided that the bedroom is ONLY set up as an office. That is, no bed, TV or other stuff. You can stretch it a bit, considering a TV is also a monitor, a couch is also a visitor couch. Whatever route you choose you have to be able to justify what everything is doing there in case of a visit from the authorities. I am (was) in exactly the same situation for two years and had no problem deducting ~30% of the housing costs. That is, the usage of bathroom and utilities is calculated as proportional to the surface area given to the office. It might make more sense to move into a larger apartment just so you can have one designated office room. Edit: the above applies in Germany, YMMV, IANAL, etc. EU is pretty consistent though in regulations and as far as I know the above aplies in most EU countries.
"According to this post on TurboTax forums, you could deduct it as an ""Unreimbursed Employee"" expense. This would seem consistent with the IRS Guidelines on such deductions: An expense is ordinary if it is common and accepted in your trade, business, or profession. An expense is necessary if it is appropriate and helpful to your business. An expense does not have to be required to be considered necessary. Office rent is not listed explicitly among the examples of deductible unreimbursed employee expenses, but this doesn't mean it's not allowed.  Of course you should check with a tax professional if you want to be sure." If it's a legitimate cost of doing business, it's as deductible as any other cost of doing business. (Reminder: be careful about the distinctions between employee and contractor; the IRS gets annoyed if you don't handle this correctly.) I heard that a C-Corp being a one person shop (no other employees but the owner) can pay for the full amount 100% of personal rent if the residence is being used as a home office. Sure. Especially if you don't mind being audited. Technically, it doesn't matter how the money gets where it goes as long as the income tax filings accurately describe the tax situation. But the IRS hates it when you make personal expenses from a business account, even if you've paid the required personal income tax (because their computers simply aren't smart enough to keep up with that level of chaos). Also, on a non-tax level, commingling of business and personal funds can reduce the effectiveness of your company's liability protection and you could more easily become personally liable if the company goes bankrupt. From what I understand the 30% would be the expense, and the 70% profit distribution. I recommend you just pay yourself and pay the rent from your personal account and claim the allowed deductions properly like everyone else. Why & when it would make sense to do this? Are there any tax benefits? Never, because, no. You would still have to pay personal income tax on your 70% share of the rent (the 30% you may be able to get deductions for but the rules are quite complicated and you should never just estimate). The only way to get money out of a corporation without paying personal income tax is by having a qualified dividend. That's quite complicated - your accounting has to be clear that the money being issued as a qualified dividend came from an economic profit, not from a paper profit resulting from the fact that you worked hard without paying yourself market value. For stocks, bonds, ETF funds and so on - Taxed only on realised gain and losses are deductible from the gain and not from company's income. Corporate tax is calculated only after all expenses have been deducted. Not the other way around. Real estate expenses can be deducted because of repairs and maintenance.  In general all expenses related to the operation of the business can be deducted. But you cannot use expenses as willy nilly, as you assume. You cannot deduct your subscription to Playboy as an expense. Doing it is illegal and if caught, the tours to church will increase exponentially. VAT is only paid if you claim VAT on your invoices. Your situation seems quite complicated. I would suggest, get an accountant pronto. There are nuances in your situation, which an accountant only can understand and help. "You are pushing your luck, but not because you're not in the US, because it is likely that you're not qualified. From what you said, I doubt you can take it (I'm not a professional though, get a professional opinion). You say ""dedicated space"". It has to be an exclusive room. You cannot deduct 10 sq. ft. from your living room because your computer that is used wholly for your business is there. It has to be a room that is used exclusively for your business, and for your business only. I.e.: nothing not related to the business is there, and when you're there the only thing you do is working on your business. Your office doesn't have to be in the US necessarily, to the best of my knowledge. Your office must be in your home. If you take primary residence exclusion as part of your FEI, then I doubt you can deduct as well." I am a freelancer based in Europe and I want to tell you: - if you are a freelancer, then you INVOICE your Swizzerland based client The word salary is improper. - So your client will DEDUCE the invoice from its taxes, and NOT pay income tax on top of that invoice. Because invoice = expense.  So, ONLY YOU pay income tax in India. Your client pays no tax at all, not in India, not in Swizzerland. As you are a freelancer and not employee, the company has no obligation to pay employer taxes for you. A company  has financial benefits from working with a freelancer. "Even though you will meet the physical presence test, you cannot claim the FEIE because your tax home will remain the US. From the IRS: Your tax home is the general area of your main place of business, employment, or post of duty, regardless of where you maintain your family home. Your tax home is the place where you are permanently or indefinitely engaged to work as an employee or self-employed individual. Having a ""tax home"" in a given location does not necessarily mean that the given location is your residence or domicile for tax purposes.   ...   You are not considered to have a tax home in a foreign country for any period in which your abode is in the United States. However, your abode is not necessarily in the United States while you are temporarily in the United States. Your abode is also not necessarily in the United States merely because you maintain a dwelling in the United States, whether or not your spouse or dependents use the dwelling.   ...   The location of your tax home often depends on whether your assignment is temporary or indefinite. If you are temporarily absent from your tax home in the United States on business, you may be able to deduct your away from home expenses (for travel, meals, and lodging) but you would not qualify for the foreign earned income exclusion. If your new work assignment is for an indefinite period, your new place of employment becomes your tax home, and you would not be able to deduct any of the related expenses that you have in the general area of this new work assignment. If your new tax home is in a foreign country and you meet the other requirements, your earnings may qualify for the foreign earned income exclusion.   If you expect your employment away from home in a single location to last, and it does last, for 1 year or less, it is temporary unless facts and circumstances indicate otherwise. If you expect it to last for more than 1 year, it is indefinite.   If you expect your employment to last for 1 year or less, but at some later date you expect it to last longer than 1 year, it is temporary (in the absence of facts and circumstances indicating otherwise) until your expectation changes. For guidance on how to determine your tax home refer to Revenue Ruling 93-86. Your main place of business is in the US and this will not change, because your business isn't relocating. If you are intending to work remotely while you are abroad, you should get educated on the relevant laws on where you are going. Most countries don't take kindly to unauthorized work being performed by foreign visitors. And yes, even though you aren't generating income or involving anyone in their country, the authorities still well may disapprove of your working. My answer to a very similar question on Expatriates." You need to set your status as self-employed the day you started online work. If that date is a little ambiguous (as is usually the case with online business), you can start with the day you first made any money. Yes, you can deduct expenses from your revenue. But you have to be sure that the expenses were purely business related.  This is how it goes: You inform HMRC about the day you started work. HMRC will assign you a UTR (Unique Tax Reference) number. Depending on how much you make you might or might not need to pay Class 2 NI contributions. You'll need to tell HMRC how much you expect to earn in the current tax year. Finally, you'll need to complete a Self-Assessment at the end of the tax year. I highly recommend setting up a business banking account. Here is a link that discusses being part-time self-employed in the UK. It looks like you can.  Take a look at these articles: http://www.googobits.com/articles/1747-taking-an-itemized-deduction-for-job-expenses.html http://www.bankrate.com/finance/money-guides/business-expenses-that-benefit-you.aspx http://www.hrblock.com/taxes/tax_tips/tax_planning/employment.html But of course, go to the source: http://www.irs.gov/publications/p529/ar02.html#en_US_publink100026912 From publication 529: You can deduct certain expenses as   miscellaneous itemized deductions on   Schedule A (Form 1040 or Form 1040NR).   You can claim the amount of expenses   that is more than 2% of your adjusted   gross income. You figure your   deduction on Schedule A by subtracting   2% of your adjusted gross income from   the total amount of these expenses.   Your adjusted gross income is the   amount on Form 1040, line 38, or Form   1040NR, line 36. I hope that helps.  Happy deducting! Before starting to do this, make sure that you are squeaky clean in all aspects of your tax preparation and are prepared to back up any claims that you make with documentation. Home office deductions are a huge red flag that often trigger audits. Follow mbhunter's advice and be incredibly meticulous about following the rules and keeping records. I am a very light TurboTax user and have expensed a laptop in the past (since it was used exclusively for work) and used the itemized deduction there and has no issues.  Just not sure if there was a limit or anything of note to realize ahead of time.  Thanks! The general rule is: Generally, in order to claim a business deduction for your home, you must use part of your home exclusively and regularly: Exclusively seems to be the toughest standard and I do not know exactly how strict the IRS's interpretation is. Working in your living room where you regularly watch TV and have people over on the weekends would seem to fail that test. A separate room with your computer in it would pass it. If it was your only computer and you regularly played online games with it, that would seem to be a grey area.  The IRA booklet covering this area is here http://www.irs.gov/pub/irs-pdf/p587.pdf I know people that have rented rooms in other places or made use of rental offices for this purpose. According to page 107 of the instructions for schedule A for form 1040 : Include taxes (state, local, or foreign) paid on real estate you own that was not used for business. ... If you want to make a business out of her property and be her agent in the management, you might be able to work with an accountant on this, but it won't be a valid personal deduction. "There are way too many details missing to be able to give you an accurate answer, and it would be too localized in terms of time & location anyway -- the rules change every year, and your local taxes make the answer useless to other people. Instead, here's how to figure out the answer for yourself. Use a tax estimate calculator to get a ballpark figure. (And keep in mind that these only provide estimates, because there are still a lot of variables that are only considered when you're actually filling out your real tax return.) There are a number of calculators if you search for something like ""tax estimator calculator"", some are more sophisticated than others. (Fair warning: I used several of these and they told me a range of $2k - $25k worth of taxes owed for a situation like yours.) Here's an estimator from TurboTax -- it's handy because it lets you enter business income. When I plug in $140K ($70 * 40 hours * 50 weeks) for business income in 2010, married filing jointly, no spouse income, and 4 dependents, I get $30K owed in federal taxes. (That doesn't include local taxes, any itemized deductions you might be eligible for, IRA deductions, etc. You may also be able to claim some expenses as business deductions that will reduce your taxable business income.) So you'd net $110K after taxes, or about $55/hour ($110k / 50 / 40). Of course, you could get an answer from the calculator, and Congress could change the rules midway through the year -- you might come out better or worse, depending on the nature of the rule changes... that's why I stress that it's an estimate. If you take the job, don't forget to make estimated tax payments! Edit: (some additional info) If you plan on doing this on an ongoing basis (i.e. you are going into business as a contractor for this line of work), there are some tax shelters that you can take advantage of. Most of these won't be worth doing if you are only going to be doing contract work for a short period of time (1-2 years). These may or may not all be applicable to you. And do your research into these areas before diving in, I'm just scratching the surface in the notes below." "The relevant IRS publication is 526, Charitable Contributions. The section titled ""Contributions you cannot deduct"" begins on page 6; item 4 reads: ""The value of your time or services."" I read that to mean that, if the website you built were a product, you could deduct its value. I don't understand the legal distinction between goods and services I originally said that I believe that a website is considered a service. Whether a website is a service or a product appears to be much more controversial that I originally thought. I cannot find a clear answer. I'm told that the IRS has a phone number you can call for rulings on this type of question. I've never had to use it, so I don't know how helpful it is. The best I can come up with is the Instructions for Form 1120s, the table titled ""Principal Business Activity Codes,"" starting on page 39. That table suggests to me that the IRS defines things based on what type of business you are in. Everything I can find in that table that a website could plausibly fall under has the word ""service"" in its name. I don't really feel like that's a definitive answer, though.  Almost as an afterthought, if you were able to deduct the value of the website, you would have to subtract off whatever the value of the advertisement is. You said that it's not much, but there's probably a simple way of estimating that."
