Income and taxes with subcontracting?
Since you say 1099, I'll assume it's in the US. :) Think of your consulting operation as a small business. Businesses are only taxed on their profits, not their revenues. So you should only be paying tax on the $700 in the example you gave. Note, though, that you need to be sure the IRS thinks you're a small business. Having a separate bank account for the business, filing for a business license with your local city/state, etc are all things that help make the case that you're running a business. Of course, the costs of doing all those things are business expenses, and thus things you can deduct from that $1000 in revenue at tax time.
"Does the money lending between us need to be reported in our tax   reports? No. Will he be taxed more because of lending the money to me? Yes. Will I be taxed more because of borrowing the money from him? No. How shall we report it so as to minimize our taxes? You cannot. What is reported on your tax returns is the income. A loan is not an income, so nothing gets reported. However, when you repay the loan, assuming it has interest, the lender has income: the interest. Interest income is reported on schedule B of the regular (1040/1040A) tax return (or, in the case of non-resident for tax purposes, on line 9 of 1040NR). It is taxed as ordinary income, and since you're both foreigners - the lender should look into the treaty provisions that might be relevant. Generally it is not exempt from taxable income based on treaty exemptions for students (which is only for earned income), but there might be other rules in the treaty regarding interest income. If there's no (fair market or higher) interest, then there's ""assumed"" interest at the IRS mandated rates, which is considered a gift. If it amounts to more than the yearly gift exemption, the lender may be liable for gift tax (depending on the lender's and your status, and again - see treaties). ""Loan"" without an obligation to repay and without actual repaying will also be considered a gift for tax purposes. If the lender has no intentions of having the loan repaid (i.e.: making a gift), it will be better to pay your tuition bills instead of actually giving you the money: tuition is exempt from gift tax. Talk to a CPA/EA licensed in your state for a proper tax advice on this issue." I'm not sure where you are, but in the United States capital gains are taxed at a lower rate than other types of income. On the 1040, captial gains income is separated from earned income, and income tax is calculated just on earned income. Then capital gains tax is calculated on capital gains income, and then added to income tax afterward. It also depends on where you work. If you move your home and your job then the date you establish residency in the new state is the key date. All income before that date is considered income for state 1, and all income on or after that date is income for state 2.  If there is a big  difference in income you will want to clearly establish residency because it impacts your wallet. If they had the same rates moving wouldn't impact your wallet, but it would impact each state. So make sure when going from high tax state to low tax state that you register your vehicles, register to vote, get a new drivers license... It becomes more complex if you move your home but not your job. In that case where you work might be the deciding factor. Same states have agreed that where you live is the deciding factor; in other cases it is not. For Virginia, Maryland, and DC you pay based on where you live if the two states involved are DC, MD, VA. But if you Live in Delaware and work in Virginia Virginia wants a cut of your income tax.  So before you move you need to research reciprocity for the two states. From Massachusetts information for Nonresident and Part-Year Resident Income, Exemptions, Deductions and Credits Massachusetts gross income includes items of income derived from   sources within Massachusetts. This includes income: a few questions later: Massachusetts residents and part-year residents are allowed a credit   for taxes due to any other jurisdiction. The credit is available only   on income reported and taxed on a Massachusetts return. Nonresidents   may not claim the taxes paid to other jurisdiction credit on their   Massachusetts Form 1-NR/PY. The credit is allowed for income taxes paid to: The credit is not allowed for: taxes paid to the U.S. government or a   foreign country other than Canada; city or local tax; and interest and   penalty paid to another jurisdiction. The computation is based on comparing the Massachusetts income tax on   income reported to the other jurisdiction to the actual tax paid to   the other jurisdiction; the credit is limited to the smaller of these   two numbers. The other jurisdiction credit is a line item on the tax form but you   must calculate it on the worksheet in the instruction booklet and also   enter the credit information on the Schedule OJC. So if you move your house to New Hampshire, but continue to work in Massachusetts you will owe income tax to Massachusetts  for that income even after you move and establish residency in New Hampshire. There are too many nuances to the question asked to explore fully but here are a few points to keep in mind. If you are a cash-basis taxpayer (most individuals are), then you are not required to pay taxes on the money that has been billed but not received as yet.  If you operate on an accrual basis, then the income accrues to you the day you perform the service and not on the day you bill the client. You can make four equal payments of estimated tax on the due dates, and if these (together with any income tax withholding from wage-paying jobs) are at least 90% of your tax liability for that year, then you owe no penalties for underpayment of tax regardless of how your income varied over the year. If your income does vary considerably over the year (even for people who only have wages but who invest in mutual funds, the income can  vary quite a bit since mutual funds typically declare dividends and capital gains in December), then you can pay different amounts in each quarterly installment of estimated tax. This is called the annualization method (a part of Form 2210 that is best avoided unless you really need to use it).  Your annualized income for the payment due on June 15 is 2.4 = 12/5 times your taxable income through May 31. Thus, on Form 2210, you are allowed to assume that your average monthly taxable income  through May 31 will continue for the rest of the year. You then compute the tax due on that annualized income and you are supposed to have paid at least 45% of that amount by June 15. Similarly for September 15 for which you look at income through August 31, you use a multiplier of 1.5 = 12/8 and need to pay 67.5% of the tax on the annualized income, and so on.  If you miscalculate these numbers and pay too little tax in any installment, then you owe penalties for that quarter.  Most people find that guesstimating the tax due for the entire year and paying it in equal installments is simpler than keeping track of nuances of the annualized method. Even simpler is to pay 100% of last year's tax in four equal installments (110% for high earners) and then no penalty is due at all. If your business is really taking off and your income is going to be substantially higher in one year, then this 100%/110% of last year's tax deal could allow you to postpone a significant chunk of your tax bill till April 15. Ethically, you and your landlord should always report both income and expense as there technically exists a service and a rent. So it is subject to taxation. On the other hand, it can be considered an exchange of a simple favour and if it doesn't involve a money exchange or any profits (I am assuming that you are not selling what you or your landlord produce on the market) no value can be calculated thus no taxation can be applied. This changes though if a contract is involved, as a legal value can be estimated. Caution: These subjects can vary on an extreme level of specificity, of what can and cannot be claimed as income and expense, which can vary per country, state, province and even per judge, as well as the nature and sector of the work. Also, if you intend to formalize this relationship, the type of contract and reporting forms do vary per state as well. So it might be best to confirm it with a local legal advisor to avoid unfortunate surprises. Don't overthink it. As an employee, whether of your own corporation or of someone else, you get a salary and there are deductions taken out. As the owner of a business you get (hopefully) business profits as well. And, in general, you often have other sources of income from investments, etc. Your estimated tax payments are based on the difference between what was withheld from your salary and what you will owe, based on salary, business income, and other sources. So, in essence, you just add up all the income you expect, estimate what the tax bill will be, and subtract what's been withheld. That's your estimated tax payment. Your best approach is to assess rent levels in your local area for offices of a similar size. You need to take into account all the usuals - amenities, parking, etc, just as if your home-office was provided by a third-party. Get your $/sq ft and work out the monthly amount. With this figure, you need to then work out what % of it you can charge. If the space is used exclusively for the business, charge 100%. If it's used about half the time, charge 50%, etc. I would strongly advise you to do two things - 1. make sure your accountant and your attorney help you get this squared away. 2. document everything about how you arrived at the cost. Nothing fancy, but dates, realtors, addresses, $/sq foot. A simple table will do. By doing these two things, if the IRS should come around to chat, you should be covered. "I agree with some of the points of the other answers but why not avoid all the guesswork? I highly recommend you not charge him now. Wait until the end of the year when you have much more information about both of your companies and then you can run the numbers both ways and decide if it would benefit you (collectively). If either of your businesses runs on a cash basis and you decide to invoice, just make sure the check is deposited before Dec 31. Update: If you want to do this for 2016, at least your husband's business would have to be using an accrual basis (since it's too late to take the deduction on a cash basis). Simply run the numbers both ways and see if it helps you. If it doesn't help enough to warrant it for 2016 you could rerun the numbers near the end of 2017 to see if it helps then. Diclaimer: I think it's OK to do this type of manipulation for the scenario you described since you have done (or are doing) the work and you are charging a reasonable fee, but realize that you shouldn't manipulate the amount of the invoice, or fabricate invoices. For example, you shouldn't ever think about such things as: ""If I invoice $50K instead of $3K, will that help us?"""
