Can I write off time I spent working on my business?
To expand a little on what littleadv said, you can only deduct what something cost you. Even if you had done volunteer work for a charity as a sole prop you could only deduct your actual costs. If you paid an employee to do charity work or to learn something related to the business that would be deductible as a normal business expense.  Some common sense would show that if you could deduct something that didn't cost you anything (your time) you could deduct away all of your income and avoid paying taxes altogether. Back to your more nuanced question could 2 businesses you own bill each other for services? Yes, but you will still have to pay taxes for money earned under each of them. You will also need to be careful that the IRS does not construe the transactions as being done solely to lower your tax bill. No, you cannot write off time, period. You should price the time spent into your product. I, occasionally, work on side projects of my own and forgo the   possibility of earning direct income for that time. Income not earned is income not taxed, so there's nothing to deduct.
IRS Publication 463 is a great resource to help you understand what you can and can't deduct.  It's not a yes/no question, it depends on the exact company use, other use, and contemporaneous record keeping. How do I account for this in the bookkeeping? Here is an example below:  This is how you would accurately depict contributions made by an owner for a business. If you would want to remove money from your company, or pay yourself back, this would be called withdrawals. It would be the inverse of the first journal entry with cash on the credit side and withdrawals on the debited side (as it is an expense).  You and your business are not the same thing. You are two different entities. This is why you are taxed as two different entities. When you (the owner) make contributions, it is considered to be the cash of the business. From here you will make these expenses against the business and not yourself.  Good luck, Only if your work on the side is making you at least £60,000 profit a year. The overheads are just not worth it if you make less. Working as a sole trader, you can still claim for expenses incurred in the course of your business. You can also claim a percentage of your computer costs, even though you may use the computer for gaming. This is not unreasonable as the computer is necessary for your work. The Inland Revenue accept the fact that some assets are part work-related. In your case, as a web and mobile phone developer, I expect the percentage to be at least half, if not a lot more. If you need to travel in the course of your work you can claim a percentage for your car. You can include other small expenses such as telephone, stationery, electricity etc but don't go overboard. The important point to remember is that you must be able to defend the expenses claimed as work-related, so long as you can do this there is no problem. Remember to keep good records of all your expenses. This is on-going throughout the year and is much more work than filling out your tax return. The software on the IR self-assessment site is excellent, so it's conceivable that you may not need an accountant if you are prepared to do your own tax return. However, if you feel unsure employ an accountant initially and take it from there. "That works for something like consulting where you are advising the client on specific things but for accounting jobs like Tax and Audit work which have been very commoditized  it's expected to only bill the client for ""productive hours"" because the project only has a set budget and we need to get the work done. My work hours is seen as a cost to my team because my project needs to make money which the partner/manager/senior are all responsible for keeping man hours down. (Again that's hours chargeable to the client wasted hours in the day don't count).  And then on top of that we need to hit a certain number of chargeable client hours per week.    It's an annoying balance" How much is your time worth This has been useful for me, judging things based on how much their time value is worth to me, weighted more heavily than their actual worth. For instance, there was a time when I used to work on the weekends and pay to have my laundry done. Doing the laundry myself would have cost 25 cents, but taken two hours at least. Since I was making $45 an hour, I would have lost $90 dollars by doing my laundry, instead of paying specialists $28 to do it for me, much better than I would. Your own capital should begin growing at a rate that makes many MANY things worth less than the time it takes for you to entertain it. So in your cable bill example, you shouldn't have argued for a $5 credit for two hours, unless you make $2.25 an hour, after tax. This is simplistic, as you would extrapolate how much this would cost you over a year or two, but such cost benefit analysis' become easy with this simple concept. This can also be used to rationalize your lavish expenditures. Such as not really comparing the costs for a flight, because its a 2 hour flight for $400 and you've found yourself making at least $200 an hour with your $416,000 annual earnings and capital gains. This will cure your frugality while retaining safe guards on your spending. "As long as the losing business is not considered ""passive activity"" or ""hobby"", then yes. Passive Activity is an activity where you do not have to actively do anything to generate income. For example - royalties or rentals. Hobby is an activity that doesn't generate profit. Generally, if your business doesn't consistently generate profit (the IRS looks at 3 out of the last 5 years), it may be characterized as hobby. For hobby, loss deduction is limited by the hobby income and the 2% AGI threshold." "I did this a couple of years ago, and boy do I regret it. After many months of delayed, and new faces coming onto the team for a short period before leaving, there wasn't much hope to ever complete the project. I ended up accumulating debt (About 4.5 grand) that I am still paying off because I chased my dream. Unfortunately, anything can happen when you choose to pursue a goal. It can get delayed, stopped, or outright fail. At the bare minimum, you would best be prepared to deal with delays, competing products, and outright failures. If you say ""I have enough money to last me 12 months and I expect to take 7 months"", then you best be prepared to answer: These are just a handful of ideas, and there are plenty more that would need to be addressed. Probably the best thing that I have seen a few friends do is to ask for reduced hours. Working part time allows you more time while reducing, but not eliminating, the pay. Even better is that depending on your company, you could ask to go back to full time if your startup didn't work out. Another option is to do what I'm doing currently: Find a job with lots of downtime. My job is critical and the market here is starved of good techs. Even then, I have a solid 2-4 hours of work each day. The other 4-6 hours I can spend on my personal projects that may eventually lead into a startup. If you plan to do this though, make sure to read your agreements carefully. There may be restrictions on copyright and the likes by working on a personal project on company property. If you do plan to go this route, you might want to consult a lawyer (like I did) to make sure you won't get screwed later." Use one journal entry, and split the expenses into the appropriate accounts. This can happen even if you never mix business and personal on the same receipt: say you order office supplies (which where I live are immediately deductible as an expense) and software or hardware (which must be depreciated because they are assets) on the same order. We have an account called Proprietors Loan which represents money the company is lending to the humans who own it, or that the humans are lending to the company. Were I to pay for my personal lunch on a business credit card, it would go through that account, increasing the amount the company has lent me or decreasing the amount I have lent it. Similarly if I made a business purchase with a personal card it would go through that account in the other direction. Where I live, I can lend my company all the money I want any time, but if the company lends me money there can't be an outstanding balance over the corporate year end. If you make two credit card entries of 5 and 10 when you go to reconcile your accounts it will be harder because you'll have to realize they together match the single 15 line on your statement. Making a single entry (your A option) will make reconciling your statement much easier. And that way, you'll probably reconcile your statements, which is vital to knowing you actually recorded everything. You would report it as business income on Schedule C.  You may be able to take deductions against that income as well (home office, your computer, an android device, any advertising or promotional expenses, etc.) but you'll want to consult an accountant about that. Generally you can only take those kinds of deductions if you use the space or equipment exclusively for business use (not likely if it's just a hobby).  The IRS is pretty picky about that stuff. "The government thought of that a long time ago, and has any loophole there plugged. Like if you set up a company to buy a car and then allow you to use it ... You can use the car for company business, like driving to a customer's office to make a sales call or delivery, and the cost of the car is then tax deductible. But the company must either prohibit personal use of the car, or keep a log of personal versus business use and the personal use becomes taxable income to you. So at best you'd get to deduct an expense here and then you'd have to add it back there for a net change in taxable income of zero. In general the IRS is very careful about personal use of business property and makes it tough to get away with a free ride. I'm sure there are people who lie about it and get away with it because they're never audited, but even if that causes you no ethical qualms, it's very risky. I don't doubt that there are people with very smart lawyers who have found loopholes in the rules. But it's not as simple as, ""I call myself a business and now all my personal expenses become tax deductible business expenses."" If you could do that, everybody would do it and no one would pay taxes. Which might be a good thing, but the IRS doesn't see it that way." "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." Your freelance income will not qualify you for the work-from-home deductions, for that you would need a T2200 form signed by your employer. But, you are allowed to be self employed as a sole-proprietorship while still being an employee of another company. If you take that route, you'll be able to write-off even more expenses than those you linked to. Things like a portion of your internet bill can be claimed, for example. But note that these deductions would only apply to offset the self-employment income, so if you're not earning very much from the freelance work, it might not be worth all the hassle. Filing taxes when self-employed is definitely more complicated, and many people will get professional tax preparation help - at least for the first time. You should check several things: How your business can deduct your child care expenses is beyond me. If your mother-in-law starts a business as a neighborhood babysitter, she might get some deductions for her related expenses though. "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." 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.
