What are the tax implications if I do some work for a company for trade, rather than pay?
Such activity is normally referred to as bartering income. From the IRS site - You must include in gross income in the year of receipt the fair market value of goods or services received from bartering. Generally, you report this income on Form 1040, Schedule C (PDF), Profit or Loss from Business (Sole Proprietorship), or Form 1040, Schedule C-EZ (PDF), Net Profit from Business (Sole Proprietorship). If you failed to report this income, correct your return by filing a Form 1040X (PDF), Amended U.S. Individual Income Tax Return. Refer to Topic 308 and Amended Returns for information on filing an amended return. Yes, the business can count that as an expense but you will need to count that as income because a computer = money. Bartering is a tricky discussion. Yes, it definitely applies when you are self-employed and do a job that you would charge anyone else for, but what if you are helping a friend in your spare time? If you receive something in exchange, the value of the item you received would be your income, but what if you don't receive anything in exchange? If the company bought a computer that they loan to you to do occasional work for them, there's no reason you couldn't take the computer home and have that company retain ownership of the property. They could still expense the depreciation of the computer without giving it to you. If it were a car though, you would have to count mileage for personal use as income. What if you exchange occasional tech support for the use of an empty desk and Internet connection? As long as they aren't renting desks for money to others, there's probably no additional marginal cost to them if they allow you to use the space, so the fair market value question breaks down.
There are two totally different things: There is your limited company, and there is yourself.  Your limited company will absolutely have to pay 20% corporation tax on all its profits. The profits are the income of the limited company (you say it's £5,000 a year) minus all expenses. Usually you would pay yourself a salary, which immediately reduces your profits. And of course the payment to the accountant will reduce the profits.  If the limited company is your only source of income, the usual method is to pay yourself £10,600 salary a year, possible pay money into a pension for yourself which is tax free and reduces the company's profits, pay 20% corporation on the rest, and pay yourself a dividend twice a year. Unless you have another job where you make a lot of money, you should have paid all that money to yourself as income and paid zero corporation tax.  And may I say that if you made £5,000 a year, then there is most likely not enough going on to justify that an accountant charges you £600. You should be able to find someone doing it cheaper; I cannot imagine that he or she had to do a lot of work for this. The question seems to be from the point of view actual sales and not its impact on one's taxation. In case you just want to sell, why brokers will respond differently each times. Either there may be issues with ownership and/or the company whose shares it is? In case you feel that the issues lies with brok In Australia, any income you earn is taxable despite where it came from. Using your example your taxable income is $70,000. Keep in mind that with a business even as a sole trader any business expenses that contribute to the earning of your business income is deductible, reducing the final amount of tax you'll have to pay.  The ATO website has lots of good information and examples to look at including tax rates.  If your total income is pushing  into a higher tax bracket over 30c tax per $1 earned, it may be worth looking at shifting your business to operate under a company structure that just has a fixed tax rate around 30c per $1.  That said, for me, I don't want the paperwork overhead of a company yet so I'm running my side business as a sole trader too. I'd rather do that and keep it easy for now while my business gets profitable that waste time on admin structures for tax reasons even if in the shortterm it may mean slightly higher tax. In the end, you only pay tax on profit (income minus expenses) as opposed to raw/gross income.  For more info there are good books in the bookshops or local library (to read free) on starting a business on the side while still working. They discuss these issues too. There are ups and downs to doing this.  This isn't a taxable gain, because it's borrowed money that will be repaid. Whether there are restrictions or not depends upon your contract with the seller and your bank. If the concessions are for health & safety related repairs, your bank may require you to complete the work before closing or within a certain period of time. Overall: Upsides Downsides "Your wages are an expense to your employer and are therefore 100% tax deductible in the business income.  The company should not be paying tax on that, so your double-tax scenario, as described, isn't really correct. [The phrase ""double taxation"" with respect to US corporations usually comes into play with dividends.  In that case, however, it's the shareholders (owners) that pay double.  The answer to ""why?"" in that case can only be ""because it's the law.""]" "Your ""average company and taxpayer"" generally wouldn't have significant off-shore/foreign income. In the U.S., for example, even if you have your employer deposit all of your salary to an account at a foreign bank, they would still report it to the IRS as income. Removing the money from your home country isn't what gets it out of being taxed, it's that the money was never in your home country." 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. "ECI is relevant to non-resident aliens who are engaged in trade or business in the US. For that, you have to be present in the US, to begin with, or to own a business or property in the US. So the people to whom it is relevant are non-resident aliens in the US or business/property owners, not foreign contractors.  From the IRS: The following categories of income are usually considered to be   connected with a trade or business in the United States. You are considered to be engaged in a trade or business in the United States if you are temporarily present in the United States as a   nonimmigrant on an ""F,"" ""J,"" ""M,"" or ""Q"" visa. The taxable part of any   U.S. source scholarship or fellowship grant received by a nonimmigrant   in ""F,"" ""J,"" ""M,"" or ""Q"" status is treated as effectively connected   with a trade or business in the United States. If you are a member of a partnership that at any time during the tax year is engaged in a trade or business in the United States, you   are considered to be engaged in a trade or business in the United   States. You usually are engaged in a U.S. trade or business when you perform personal services in the United States. If you own and operate a business in the United States selling services, products, or merchandise, you are, with certain exceptions,   engaged in a trade or business in the United States. For example,   profit from the sale in the United States of inventory property   purchased either in this country or in a foreign country is   effectively connected trade or business income. Gains and losses from the sale or exchange of U.S. real property interests (whether or not they are capital assets) are taxed as if you   are engaged in a trade or business in the United States. You must   treat the gain or loss as effectively connected with that trade or   business. Income from the rental of real property may be treated as ECI if the taxpayer elects to do so." Yes, you would have to report the gain. It is not relevant that you traded the stock previously, you still made a profit on the trade-at-hand. Imagine if for some reason this type of trade were exempt. Investors could follow the short term swings of volatile stocks completely tax-free. It's not quite clear what you are asking, so I'll answer a few possible interpretations. Businesses pay taxes on their profits. So if your business took a million pounds in revenue (e.g. sold a million pounds worth of stuff) then you would subtract (roughly speaking) everything the business spent on making and selling that stuff, and pay taxes only on the profit. VAT however is a different matter, and you would have to pay VAT on all of that income (technically the VAT portion isn't even income - it's tax you are forced to collect on behalf of the government). If your business made a million pounds pounds profit, it would pay tax on all of that million (subject to what a tax accountant can do to reduce that, which ought to be considerable).  You can't subtract your personal living expenses like that. However the company can pay you a salary, which counts as an expense and the company doesn't pay tax on that. You might also take some money from the company as dividends. Both salary and dividends count as personal income to yourself, and you will need to pay personal income tax on them.  As for the Ferrari, it depends on whether you can justify it as a business expense. A lot of companies provide cars for their employees so that they can use them for business - however you have to be able to show that IS for business, otherwise they are taxed like salary. The rules for company cars are quite complicated, and you would need an accountant. If this is a real rather than hypothetical situation, definitely get a tax accountant involved. "I'm not 100% certain on boats, since they aren't typically sold for a gain, but the tax base of an asset is typically the cost of the asset plus the cost of any improvements, so your $15,000 gain looks right (check with a CPA to be certain, though, if you can).  Your ""cost basis"" would be $50,000 + $25,000 = $75,000, and your net gain would be $90,000 - $75,000 = $15,000.  The result is the same, but the arithmetic is organized a little differently. I am fairly confident you cannot include your time in the ""cost of improvements"".  If you incorporated and ""paid yourself"" for the time, then the payment would be considered income (and taxed), if it was even allowed. Depending on your tax bracket that may be a WORSE option for you. You can look at it this way - you only pay the tax on the $15k gain versus paying someone else $15k to do the labor." "Keep in mind that all of the information below assumes: That being said, here are some examples of national tax laws relating to barter transactions. Obviously this isn't an exhaustive list, but based on my grossly non-representative sample, I think it's fairly safe to assume that barter transactions are more likely taxable than not.  You're referring to a barter system; in the United States, the IRS is very specific about this (see the section titled Bartering).  Bartering is an exchange of property or services. The fair market   value of goods and services exchanged is fully taxable and must be   included on Form 1040 in the income of both parties. The IRS also provides more details: Bartering occurs when you exchange goods or services without   exchanging money. An example of bartering is a plumber doing repair   work for a dentist in exchange for dental services. You must include   in gross income in the year of receipt the fair market value of goods   and services received in exchange for goods or services you provide or   may provide under the bartering arrangement. Generally, you report this income on Form 1040, Schedule C (PDF),   Profit or Loss from Business or Form 1040, Schedule C-EZ (PDF), Net   Profit from Business. If you failed to report this income, correct   your return by filing a Form 1040X (PDF). Refer to Topic 308 for   amended return information. So yes, the net value of bartered goods or services is most likely taxable. According to the Australian Tax Office: Barter transactions are assessable and deductible for income tax   purposes to the same extent as other cash or credit transactions. Her Majesty's Revenue and Customs states that: If you supply services or goods (new or second-hand) and receive other   goods or services in payment, there are two separate supplies: You must account for VAT, and so must your customer if they're   VAT-registered. The VAT treatment is the same as for part-exchanges.   You must both account for VAT on the amounts you would each have paid   for the goods or services if there had been no barter and they had   been paid for with money. Searching the website of the Federal Tax Service for the Russian/Cryllic word for barter (бартер) doesn't yield any results, but that might be because even between Google Translate and the rest of the internet, I don't speak Russian. That being said, I did manage to find this (translated from the first full paragraph of the Russian, beginning with ""Налог на доходы..."": The tax on personal income is paid by citizens of the Russian   Federation with all types of income received by them in the calendar   year, either in cash or in kind. Since bartering would probably qualify as an in kind transaction, it would likely be taxable.  The South African Revenue Service includes barter transactions in the supply of goods taxed under the VAT.  The term “supply” is defined very broadly and includes all forms of   supply and any derivative of the term, irrespective of where the   supply is effected. The term includes performance in terms of a sale,   rental agreement, instalment credit agreement or barter transaction. Look for section 3.6, Supply and Taxable Supply, found on p17 of the current version of the linked document." "In simple terms, it is a business operation when it becomes a   profit-making enterprise. It is a grey area, but there is a difference between selling   occasional personal items on eBay and selling for profit. I would imagine the sort of considerations HM Revenue & Customs would   take into account are the size of your turnover, the extent to which   you are both buying and selling, and whether you are clearly   specialising in one particular commodity as opposed of disposing of   unwanted presents or clearing the loft. http://www.ebay.co.uk/gds/When-does-eBay-selling-become-taxable-/10000000004494855/g.html I don't believe that you selling your personal camera gear will be taxable, but as the link says, it is a grey area.  They also recommend to do this It's far better than having to deal with an investigation a few years   down the line. When it comes to completing your tax return, there is a section which   is headed ""other income"", and it is here where you will enter the net   earnings from the web business. ""Net"" here means your additional income, less all expenses associated   with it. If you are still worried I would always encourage people to take a cautious approach and discuss their position with HMRC via its helpline on 08454 915 4515." If your net profit is $0, then no, you will not owe income tax as a result of providing this service. But there's a lot more to consider than just that... Before you begin you'll need to decide if this is a business or a hobby. Based on the fact that you don't intend to make a profit, you are probably going to be calling it a hobby for tax purposes. Regardless of whether it is a business or a hobby, since you will be accepting payments from people, you will need to report the income on your tax return. As both a business and a hobby you can deduct all of your expenses to bring your profit down to $0. (Assuming all the expenses are legitimate business/hobby expenses.) The main differences between business and hobby are: If you choose to run as a business you'll likely save quite a bit of money by avoiding the 2% rule, and also by being able to deduct any non-specific-customer expenses and take a loss. Be careful though that you don't go too many years with a business loss or the IRS may re-classify it as a hobby, which may include an audit. If you decide to run as a business you may need to charge a little more than just expenses to attempt to turn a profit, or at least break even. Yes, this extra income would be taxed at your marginal rate because it is increasing your total income. This does not necessarily apply to all income, however. Capital gains are taxed at a different rate. Depending on the amount of extra work, you may wish to consider setting up a corporation. Corporations are taxed entirely differently. This would also give you the opportunity to write off far more of your expenses, but be aware of double taxation. Investopedia has a good article on double taxation. The issue is that the corporation must pay taxes on the revenue and then, when you take out the money either as salary or dividends, you personally will pay tax. It may leave you better off, even with the double taxation. Dividends are taxed at a lower rate than your marginal tax rate, generally. And you can write off much more inside a corporation. If considering this, talk to an accountant and discuss your expected revenue from consulting. The accountant should be able to quantify the costs and benefits.
