Section 179 vs depreciation of laptop
I'm not a tax expert, but I think you mean Form 4562, right? If you acquire the laptop in the year for which you're filing taxes, then it is just that simple.  (At least according to my reading of 4562 instructions, and my history of accepted tax returns where I've done this for my own business.) If, however, you acquired the laptop in a previous year and have already depreciated it previously (with the plan to spread over several years), there is more complexity I believe -- you may limited in how you could accelerate the remaining depreciation. The CPA's mention of $2,500 is probably referring to the recently increased de minimis safe harbor under the final tangible property regulations (used to be $500) without an applicable financial statement. The IRS will not challenge your choice of expense or capitalization on amounts on or below $2500 if you elect the de minimis safe harbor election on your return. However, you must follow whatever you're doing for your books. (So if you are capitalizing your laptops for book purposes, you would also need to capitalize for tax purposes). Section 179 allows you to expense property that you would have otherwise have had to capitalize and depreciate. Section 179 can be annoying, especially if your LLC is treated as a passthrough, because there are recapture provisions when you dispose of the asset too early. For the tax return preparer, it makes the return preparation much more simple if there are no fixed assets to account for in the first place, which is quite possible if you are expensive all items/invoices less than $2,500.
"First, don't use Yahoo's mangling of the XBRL data to do financial analysis.  Get it from the horse's mouth: http://www.sec.gov/edgar/searchedgar/companysearch.html Search for Facebook, select the latest 10-Q, and look at the income statement on pg. 6 (helpfully linked in the table of contents).  This is what humans do. When you do this, you see that Yahoo omitted FB's (admittedly trivial) interest expense.  I've seen much worse errors. If you're trying to scrape Yahoo... well do what you must.  You'll do better getting the XBRL data straight from EDGAR and mangling it yourself, but there's a learning curve, and if you're trying to compare lots of companies there's a problem of mapping everybody to a common chart of accounts. Second, assuming you're not using FCF as a valuation metric (which has got some problems)... you don't want to exclude interest expense from the calculation of free cash flow.  This becomes significant for heavily indebted firms. You might as well just start from net income and adjust from there... which, as it happens, is exactly the approach taken by the normal ""indirect"" form of the statement of cash flows.  That's what this statement is for.  Essentially you want to take cash flow from operations and subtract capital expenditures (from the cash flow from investments section).  It's not an encouraging sign that Yahoo's lines on the cash flow statement don't sum to the totals. As far as definitions go... working capital is not assets - liabilities, it is current assets - current liabilities.  Furthermore, you want to calculate changes in working capital, i.e. the difference in net current assets from the previous quarter.  What you're doing here is subtracting the company's accumulated equity capital from a single quarter's operating results, which is why you're getting an insane result that in no way resembles what appears in the statement of cash flows.  Also you seem to be using the numbers for the wrong quarter - 2014q4 instead of 2015q3. I can't figure out where you're getting your depreciation number from, but the statement of cash flows shows they booked $486M in depreciation for 2015q3; your number is high. FB doesn't have negative FCF." 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: I'll give the credit to @Quid in the comments section of the question.  You put out $10k, you got back $20k, that's a cash gain of $10k, how the asset was valued between your purchase and sale isn't relevant. From an accounting perspective, the company is the only party that is realizing the loss (as they have sold the asset for 40K less than par). You the buyer, only get to see the initial buy and sale of such capital asset.  Example: A company purchases a car for $20,000 and after depreciation it is worth (book valued at) $2,000. It is then sold to a customer for $3,000.  Does the customer realize a loss of $1,000? No.  Does the company realize a gain of $1,000? Yes.  Your bank analogy is flawed in two ways: What?  They don't need to improve on shit, their ThinkPad line is amazing.  They are already the best laptops on the market, hands-down.  Using one right now, over 2 years old and flawless.    Plus, the little red dots are called *nipples*.  My laptop has a *nipple*.  Hehehehehe. "The downside of the store card is that the ""deal"" for using the card is typically 6-12 months of ""no payments"" or ""no interest"". In reality, the ""deal"" is deferred payments/interest. The problem is, if you miss any payment, or fail to pay the computer off in full, you'll have to pay for the accrued interest -- at a rate typically 25% or higher. That means if you buy your computer for $1,000, and pay $999 at the end of 12 months, you may have to pay $250 in accrued interest. These cards can be great deals, just be really careful!" 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. Yes, you can depreciate gifts to your business subject to the special rules in § 1011 and Regulation § 1.1011–1 and 1.167(g)–1. It is dual basis property so when you sell the item your gain/loss basis will be different. Adjusted basis of the donor for gain, FMV on the date received for the loss. Minus any depreciation you add, of course, in both cases. Extended warranty or insurance is a tricky thing.  In general, the big screen TV, or other electronics are going to become obsolete before they fail. Laptops, even Macs, are at risk for higher failure rates than other electronics.  The question remaining is whether after the item has reached its 3rd or 4th birthday, if you would already be in the market for a newer model.  In the big picture, if you have the money to buy a new replacement, or pay for a repair, you are better off to avoid the insurance. The highest failures are in the first year (aka 'infant mortality') and after N years, closer to 7-10, enough for obsolescence, than in years 2-5.
