How is income tax calculated in relation to selling used items?
If the items you sold are items you previously bought for a higher price, the money you get selling them is not income, as you are taking a loss. However, you cannot deduct such losses. If you sell anything for more than what you paid for, the difference is a gain and is taxable. See this IRS web site for the explanation: https://www.irs.gov/businesses/small-businesses-self-employed/tax-tips-for-online-auction-sellers If I sell it for $50 can I write off the $50 loss. Only if you can establish that it is a normal part of your business and that you did not get $50 worth of use out of it.  That's the technical, legal argument.  As a practical matter, it's unlikely that they'll ding you for selling something after using it, as they won't know.  If they did catch you, you would be in trouble.  You can't deduct loss due to personal use.   The larger problem is that if you sell one TV for a $50 loss, they aren't going to believe that you are in the business of selling TVs.  If you sell a larger amount for a loss, then they still are unlikely to believe that you are in business.  If you sell a large amount for an overall gain, they are unlikely to notice that you took a loss on one TV.  They could only notice that if they were already auditing you, as that wouldn't be visible in your tax forms. Yes. This income would be reported on schedule SE. Normally, you will not owe any tax if the amount is less than $400.  Practically, $100 in a garage sale is not why the IRS created the form SE. I wouldn't lose sleep over keeping track of small cash sales over the course of a year. However, if you have the information I'm not going to tell you not to report it.
Let me restate question for clarity. Facts: Question: Are there any taxes for this transaction? Answer: (Added improvements provided by Eric) Generally No. Generally, it is not considered income until you sell and the sale price is greater than the purchase price. But with currency differences, there is an additional complication, section 988 rules apply. It could result in ordinary income or loss. My experience (two purchases, Ontario, Canada) is that the property taxes are paid   by whomever is the owner on the date the tax bill comes due.  The bill might be due before the owners even decide to sell.   However: A part of the closing process is a Statement of Adjustments, in which various costs that span the tenure of two owners are split on a per-diem basis.  In your case, there would have been a charge against you of 2/365 of the tax bill on this statement at the time of closing (if you hadn't paid any 2014 taxes) The statement also includes things like flat-rate water bills, monthly cable bills, security system monitoring...  All paid by one owner or the other, but split fairly on a per diem basis at the time of closing... IRS Pub 561 says you have to use fair market value.  You cannot simply use a depreciated value. You should attempt to determine what people normally pay for comparable items, and be prepared to defend your determination with evidence in the event of an audit. If significant amounts are involved, that would be a good time to consult a tax professional (EA/CPA licensed in your state).  Generally, sale of a business is an ordinary income and you can only deduct tangible expenses, as Joe said. That would be laptops, bills, expenses per receipt, of course they must all be directly attributable to the business. You will need to be able to show that the laptops has only been used in business, recapture depreciation, etc. Same with all the rest of the expenses. If you're incorporated (i.e.: you hold this software under an S-Corp), then you're selling stocks, not business, and the tax treatment may be different, but I'm guessing this is not the case for you. I think that author does a disservice by writing such seemingly sensible articles without actually knowing how things work. If I didn’t know better, I would think this guy was teaching me something. It’s a shame he did not do research before he started writing.  Let’s say you buy a classic car. You take super good care of it, all original, mint condition. You paid cash for it out of your savings. This is a balance sheet transaction that has nothing to do with income. You traded your cash asset for a classic car asset.  Now let’s say this car is so rare and you keep it in such good condition that it gains value every year. Maybe it was worth $15k when you bought it, but this year it’s already worth $17k. Great job on making a great purchase! But is that $2k gain counted as income to you? No, it is not. The value of that asset on your balance sheet went up, but you did not make anything off of that increase in value because you have not sold it.  If you had to pay taxes on the increase in value every year, those taxes would essentially force you to sell that car to pay the taxes just because you took care of it. Additionally, in the long term, no one would want to own anything, so this would destroy the value of everyone’s stuff, but I digress.  In this example, amazon stock is the car. The author is seeing the increase in stock value adding to the balance sheets of the investors who bought the stock and confusing that with income.  Back to our example, let’s say your car increased in value $2k a year for two years and you decide to sell it for $19k - now we are about to realize some income! Since you bought it for $15k and sold for $19k, you earned an income of the difference, or $4k.   Your income wasn’t $19k, because you originally put $15k in cash into the car. That cash was already saved from income you made in the past, and it is not counted again as income in this sale.  Because you did not work for this new car sale income, but it was derived from asset growth, the income is called capital gains. You invested your capital ($15k) into the asset (car), and that asset appreciated. When you sold it, you received capital (money) back in exchange for that asset. The capital you received is more than what you invested, which is to say you gained $4k of capital by investing in and then selling your  asset (car).  Because you held the car for two years, you qualify for lower long term capital gains tax rate on that $4k. Had you sold it after year 1, you would’ve paid your regular normal income tax rate on those capital gains. Either way, you owe the tax when you sell the asset, not when it appreciates.  I’m sure you realize this already, but if we change the car to amazon stock in my story, this is exactly how it works with investors.  The author gets several things wrong   1 - amazon profits are not passed through to shareholders for income tax purposes. If amazon paid dividends, those dividends would be taxed at payout at the long term capital gains rate, and they would be paid out of cash amazon has left after it already paid corporate taxes on profits.   Amazon has decided they can add more value to investors by using cash to grow instead of paying dividends. When the investors sell the stock, they will owe capital gains on the growth of that stock. If amazon is correct that using cash to grow, then investors will effectively pay more when they sell the stock than they would pay today if dividends were paid.  2 - asset appreciation is not income. Those investors will realize the income when they sell the stock, and they will pay the tax then.   3 - he is missing the point entirely on why amazon runs a low profit or how business strategy translates into financials. Low prices are not a function of low profitability. Low profitability could be an adverse result of low pricing, but being low profit in order to be low price is a ridiculous and failing strategy. Amazon’s low pricing is a function of their unparalleled buying power, unparalleled consumer and product data, amazing logistics prowess, clever loyalty programs like amazon prime, and many other brilliant things they’ve done. Their low profitability is a function of their investment in things like amazon fresh, amazon Alexa, drone delivery, automated convenience stores, building out cloud computing infrastructure, and many other R&amp;D projects, $4 billion in original content spending for amazon prime video, and all kinds of expenditures years ahead of when they become profitable. By the time consumers want it, amazon already built it three years ago - this is the power of amazon. Sometimes multi billion dollar experiments fail, and all that money was for nothing. Sometimes they lose money for a few years and then become the infrastructure that runs a third of the internet. Amazon does not let fear of failure stop them, they invest in growth with their cash. This is how Bezos thinks - how do we build the future, not how can I avoid tax    I do need to make a disclaimer here - there could be special tax treatment of classic cars that makes my example not work. Also classic cars may not appreciate in value. I don’t know anything about classic cars, I just picked a politically neutral thing to put in my story and made some assumptions to illustrate how capital gains work. My story is definitely how stocks work, and probably cars, but I just want to point out that I don’t know shit about car collecting. It doesn't go on Schedule E at all, it goes on form 4797. The fridge should have been depreciated, over 5 years. If you sold it after 5 years, all the proceeds are taxable income taxed as depreciation recapture (25% rate) up to the allowable depreciation (your original cost basis), above which it is taxable capital gain. Whether you actually have depreciated it or not, it is really your problem, IRS doesn't care. So if 5 years of ownership passed - just write it all as taxable income on the form 4797. Otherwise, allowable depreciation prorated (and you can still amend forms 3 years back to get at least part of it). The new fridge should also be depreciated over the 5 years of its expected useful life. See form 4562. Talk to a licensed tax professional (EA/CPA licensed in your state) for details. What you are doing is barter trade. Most countries [if not all] would tax this on assumed fair value. There are instances where countries may relax this norm in border areas for a small amount.   Barter is not just for gold – one can virtually do this for any goods, i.e. sell garments in exchange for oil, sell electronic chips in exchange for consumer goods, etc. Quite a few business would flourish doing this and not exchange currency at all, hence the need for government to tax on the [assumed / calculated / arrived/ derived] fair value. A word of caution: at times this may not be fair at all and may actually cost more than had one done a transaction using currency. The way the wash sale works is your loss is added to your cost basis of the buy.  So suppose your original cost basis is $10,000.  You then sell the stock for $9,000 which accounts for your $1,000 loss.  You then buy the stock again, say for $8,500,  and sell it for $9,000.  Since your loss of $1,000 is added to your cost basis, you actually still have a net loss of $500. You then buy the stock again for say $10,500,  then sell it for $9,500.  Your $500 loss is added to your cost basis,  and you have a net loss of $1,500. Since you never had a net gain, you will not owe any tax for these transactions. Yes -- you can refund the sales tax and adjust your return. Make sure you have a copy of your customer's reseller permit on file. If the item sold was for their own use (instead of resale), then sales tax is due, so you might want to check with the customer and ask them what they want to do. The buyer of such an account is likely treating it as an asset, and if they ever resell it capital gains (or loss) would be realized. I don't see why this would be any different for the person that created the account initially, except that the basis starts at $0 making the entire sale price taxable. How you figure the value of the account before the initial sale would be more difficult, but fortunately you may not ever need to know the value (for tax purposes) until you actually sell it. Australian Goods and Services Tax is charged on the sale amount. Whatever internal accounting you do before billing the customer is of no interest to the Australian Tax Office. Capital gains taxes for a year are calculated on sales of assets that take place during that year.  So if you sell some stock in 2016, you will report those gains/losses on your 2016 tax return. I would say when starting with Gnucash to start with the level of granularity you are comfortable with while sticking to the double entry bookkeeping practices. So going through each one: Refund for Parking Pass. Assuming you treat the Parking Pass as a sunk cost, i.e. an Expense account, its just a negative entry in the Expense account which turns into a positive one in your Bank account. Yes it may look weird, and if you don't like it you can always 'pay from Equity' the prior month, or your Bank Account if you're backfilling old statements. Selling physical items. If you sold it on eBay and the value is high enough you'll get tax forms indicating you've earned x. Even if its small or not done via eBay, treat it the same way and create a 'Personal Items/Goods' Income account to track all of it. So the money you get in your Bank account would have come from there. Found jacket money would be an Equity entry, either Opening Balances into Cash or Bank account. Remember you are treating Equity / Opening Balances as the state before you started recording every transaction so both the value going into Assets (Banks,Stock,Mutual Funds) and Liabilities (Mortgage, Student Debt, Credit Card Debt) originate from there. If you don't track the accrued costs involved, then it means that the valuation of the deal will be somewhat arbitrary, but it still can be made by looking at the value of equivalent or similar goods or services. It's rather similar to accounting treatment of (noncash) gifts, for example. You make up a valuation, and as there are obvious tax reasons to make it as low as possible, the valuation should be justifiable or you risk the wrath of IRS. If you sell the same goods or services for cash, then the value of the barter deal is obvious. If this barter is the only time you're handling this particular type of goods, a wholesale price of similar items (either of your items, or the items that you're receiving in barter) could work. It's better to use the accounting equation concept: Asset + Expenses = Capital + Liabilities + Income If you purchase an asset: Suppose you purchased a laptop of $ 500, then its journal will be: If you sell the same Laptop for $ 500, then its entry will be:
