How can I work out how much a side-job contracting will be taxed for?
I would say you can file your taxes on your own, but you will probably want the advice of an accountant if you need any supplies or tools for the side business that might be tax deductible. IIRC you don't have to tell your current employer for tax reasons (just check that your contract doesn't state you can't have a side job or business), but I believe you'll have to tell HMRC. At the end of the year you'll have to file a tax return and at that point in time you'll have to pay the tax on the additional earnings. These will be taxed at your highest tax rate and you might end up in a higher tax bracket, too. I'd put about 40% away for tax, that will put you on the safe side in case you end up in the high tax bracket; if not, you'll have a bit of money going spare after paying your taxes. "Being self-employed, your ""profit"" is calculated as all the bills you send out, minus all business-related cost that you have (you will need a receipt for everything, and there are different rules for things that last for long time, long tools, machinery).  You can file your taxes yourself - the HRS website will tell you how to, and you can do it online. It's close to the same as your normal online tax return. Only thing is that you must keep receipts for all the cost that you claim.  Your tax: Assuming your gross salary is £25,000 and your profits are about £10,000, you will be paying 8% for national insurance, and 20% income tax. If you go above £43,000 or thereabouts, you pay 40% income tax on any income above that threshold, instead of 20%, but your national insurance payments stop."
4 months working from your kitchen doesn't sound like an isolated or incidental transaction. So I think that yes, that income would be taxable by NYS (and NYC/Yonkers if the kitchen is in these cities). I'm not a tax advisor, but I've done freelance work, so... If any of your side-business revenue is reported on a 1099, you're now a business owner, which is why Schedule C must be filled out. As a business owner, minimum wage doesn't apply to you. All revenue is income to you, and you owe taxes on the profit, after subtracting legitimate (verifiable) business expenses. You'll want to talk to a real tax advisor if you're going to start expensing mileage, part of your house (if you use a home office), etc. Don't forget that you'll owe self-employment tax (the employer's half of your payroll tax).  You can't save money on business taxes by paying yourself a wage and then counting it as an expense to the business. You'll definitely want to talk to a tax expert if you start playing around with finances as an (the) owner of the business. Income that is not reported on a 1099 should be reported as hobby income. "Chris, Joe's table helps.  but think this way:  there are two ways you can pay the taxes for your side-gig:  either you can send a check quarterly to the Feds, OR, you can overwithhold at your real job to cover taxes at your sidegig.  I'd do this in ""arrears"" -- after you get your first paycheck from sidegig, then adjust your real job's withholding. Except (and Joe neglected this), you're still responsible for Social Security / Medicare Tax from your sidegig.  I suspect your income at real-job is high enough that you stop paying Social Security Tax, so at least at this time of year you won't be subject to 15.4% Social Security Tax.  However, that's NOT true for the 2.9% Medicare Tax.  Remember that because you're an independent contractor being payed without withholding, YOU are responsible not only for the Medicare (and Social Security) taxes you'd be responsible for if a regular employee, but you're also responsible for what your employer's share as well." Hourly rate is not the determinant.  You could be selling widgets, not hours. Rather, there's a $30,000 annual revenue threshold for GST/HST. If your business's annual revenues fall below that amount, you don't need to register for GST/HST and in such case you don't charge your clients the tax. You could still choose to register for GST/HST if your revenues are below the threshold, in which case you must charge your clients the tax. Some businesses voluntarily enroll for GST/HST, even when below the threshold, so they can claim input tax credits. If your annual revenues exceed $30,000, you must register for GST/HST and you must charge your clients the tax.  FWIW, certain kinds of supplies are exempt, but the kind of services you'd be offering as an independent contractor in Canada aren't likely to be. There's more to the GST/HST than this, so be sure to talk to a tax accountant. References: Not as you suggest. Since you are sole prop, you are taxed on a cash basis. Within reason, you can prepay vendors - so temp to hire through an agency might appear more attractive than direct hire. But there needs to be a justification other than avoidance of taxes. So pre-paying 100k on 12/25 would look fishy as fuck. Plus your quality of candidate will suffer if you need anything other than low skill labor.  Look at your other fully deductible expenses - anything you can prepay-prepay. For example, I set my liability insurance renewal January 15 to provide optionality. But it just shifts one year into another .. Means fuckall if you are in the same marginal bracket next year.  The IRS has also relaxed depreciation on office technology. Computers are now fully deductible rather than being capitalized.  @ 500k revenue you should have a CPA and legal counsel. Simply incorporating isn't tax magic. The purpose is to limit yourersonal liability, not a tax shelter - but shitty things happen once you have employees, don't create the potential for a disgruntled employee lawsuit put your shelter at risk of court judgment.  That said, assuming you aren't dumping a hypothetical on the Internet, congrats - for all the headaches, having employees is the ultimate leverage .. it's like a xerox machine for your labor (including loss of fidelity with each copy) .. The benefits and taxes thing, in my opinion is the biggie. Most people don't realize that the cost to the company for a full-time employee with benefits can be 2x or even 3x the amount they see in their paycheck.  Health plans are extremely expensive. Even if you are having money taken from your check for health insurance, it is often just a fraction of the total cost, and the employer is subsidizing the rest.  More expensive benefits that contractors don't typically get are 401K matches and paid vacation days. When contractors call in sick or don't work because it is a national holiday, they don't get paid for that day. Also, see that line on your paycheck deducting for Social security and Medicare? That is only half of the tax. The employer pays an equal amount that is not shown on that statement. Also, they pay taxes that go towards unemployment benefits , and may be required to pay higher taxes if they churn through a lot of full-time employees. You can usually let contractors go with relative impunity . For the unemployment tax reasons, not paying for people's days off or benefits, a lot less paperwork, and less risk to the business associated with committing to full-time employees all provide value to the company. Thus companies are willing to pay more because they are getting more.  Think of it like a cell phone-contract. If you commit to a three year contract it can be a pain/expensive to get out of the deal early, but you will probably get a better rate in exchange for the risk being shifted to your end of the deal. I just scanned in a single sheet summary of my last two years tax returns. It is something our CPA does for us. How would I post it? Don't worry, I marked out all the personal information.    What is says is I paid over $50K in taxes in 2015. Last year we had one of our biggest contracts put on hold, so I only paid $20K.   I won't have this years figures, because we don't submit them to our CPA until the end of the year. However, this year, we just bought out two other owners at $1.2M, which makes me a 33% owner. The contract is getting restarted (knock on wood), which all together means my personal tax liability is going to be well over $100K.   My company is a commercial company, but we work with the government, and matter of fact some of the stuff we produce was designed and developed by the government (as is many of today's modern inventions - I think you would be surprised).   So lets tackle it one at a time. Pick one of those things that commercial does better than government.   P.s. Higher taxes doesn't mean higher for you, a lot of times it means higher for guys like me or way better than me (which I am perfectly fine with, and matter of fact would support). People who use infastructure more - like large corporations - should pay more for it... This is how a consulting engagement in India works. If you are registered for Service Tax and have a service tax number, no tax is deducted at source and you have to pay 12.36% to service tax department during filing (once a quarter). If you do not have Service tax number i.e. not registered for service tax, the company is liable to deduct 10% at source and give the same to Income Tax Dept. and give you a Form-16 at the end of the financial year. If you fall in 10% tax bracket, no further tax liability, if you are in 30%, 20% more needs to be paid to Income Tax Dept.(calculate for 20% tax bracket). The tax slabs given above are fine. If you fail to pay the remainder tax (if applicable) Income Tax Dept. will send you a demand notice, politely asking you to pay at the end of the FY. I would suggest you talk to a CA, as there are implications of advance tax (on your consulting income) to be paid once a quarter. From my blog's discussion on 2017 tax rates.  This is the final set of numbers. So, if you currently have, say $120K taxable income, every dollar above that starts getting taxed at 25%, until $153K, then 28%.  In other words, forecast your taxes based on the day job, but then the 1099 goes on top of that. "As an easy and rough rule of thumb, a job for $55,000 per year is $55 per hour as a contractor. That's roughly twice the hourly rate.  In return, the company gets the rate to vary your hours or cease your employment with less financial, legal or managerial overhead than a full time employee.  You have less stability, less benefits, perhaps need to put some time into finding another job sooner. Of course the ultimate, though less helpful, answer is ""whatever the market will bear.""" "I don't see why you would need an ""international tax specialist"". You need a tax specialist to give you a consultation and training on your situation, but it doesn't seem too complicated to me. You invoice your client and get paid - you're a 1099 contractor. They should issue you a 1099 at the end of the year on everything they paid you. Once you become full-time employee - you become a W2 employee and will get a W2 at the end of the year on the amounts paid as such. From your perspective there's nothing international here, regular business. You have to pay your own taxes on the 1099 income (including SE taxes), they have to withhold taxes from your W2 income (including FICA). Since they're foreign employers, they might not do that latter part, and you'll have to deal with that on your tax return, any decent EA/CPA will be able to accommodate you with that. For the employer there's an issue of international taxation. They might have to register as a foreign business in your state, they might be liable for some payroll taxes and State taxes, etc etc. They might not be aware of all that. They might also be liable (or exempt) for Federal taxes, depending on the treaty provisions. But that's their problem. Your only concern is whether they're going to issue you a proper W2 and do all the withholdings or not when the time comes." "The translation scheme is detailed in IRS Publication 15, ""Employer's Tax Guide"". For the 2010 version, the information is in Section 16 on Page 37. There are two ways that employers can calculate the withheld tax amount: wage bracket and percentage. Alternatively, they can also use one of the methods defined in IRS Publication 15-A. I'll assume the person making $60k/yr with 10 allowances is paid monthly ($5000/period) and married. Using the wage bracket method, the amount withheld for federal taxes would be $83 per pay period. Using the percentage method, it would be $81.23 per pay period. I don't recommend that you use this information to determine how to fill out your W-4. The IRS provides a special online calculator for that purpose, which I have always found quite accurate. Note: ""allowances"" are not the same as ""dependents""; ""allowances"" are a more realistic estimation of your tax deductions, taking into consideration much more than just your dependents." "(I'm assuming USA tax code as this is untagged) As the comments above suggest there is no ""right"" answer or easy formula.  The main issue is that you likely got into business to make money and if you make money consistently you will pay taxes.  Reinvesting generally should be a business decision where the main concern is revenue growth and taxes are an important but secondary concern. Taxes can be complicated, but for a small LLC shouldn't be that bad.  I highly recommend that you take some time closely analyze your business and personal taxes for the previous year.  Once you understand the problem better, you can optimize around it.  If it is a big concern, some companies buy software so they can estimate their taxes periodically through the year and make better decisions." "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." Sounds you need to read up on S corp structures. I think this would benefit you if you generate income even after you physically stopped working which is incomes from membership fees, royalties % of customer revenue, middle man etc...  Under the Scorp, you as the sole member must earn a wage that fair and at current market value. You pay social security and Medicare on this wage. The interesting thing here is that an Scorp can pay out earning dividends  without having to pay payroll taxes but the catch is that you, as the sole employee must earn a fair wage.   As for paying the other member you may want to look into 1099 contract work plus a finders fee. The 1099 hourly wage does not require you to pay Medicare and SS.   The common fee I'm used to is 5% of gross invoice. Then you would pay her an hourly wage. The company then bills these hours multiplied by 2 or 3 (or whatever you think is fair) to the client. Deduct expenses from this and that's your profit.   Example. Contractor brings Client A which is estimated as a  100 hour project with $100 cost in supplies and requires 2 hours of your time @ $40/hr.   You quote 100 hours @ $50 to client, client agrees and gives you down payment.   You then present the contract work to your contractor, they complete the work in 100 hours and bill you at $25.   You pay your contractor 2500 plus the 5% ($250)  and your company earns $2070 (5000 - 2500 - 100-80)  And you'll earn $80 minus the payroll tax.   Then at the end of the quarter or year or however you want to do earning payouts your LLC- Scorp will write you a check for $2070 or whatever earning % you want to take. This is then taxed at your income tax bracket.   One thing to keep in mind is what is preventing this other person from becoming your competition? A partnership would be great motivation to try and bring in as much work under the LLC. But if you start shafting people then they'll just keep the work and cut you out.
