Do I need to file taxes jointly with my girlfriend if we live together?
In Ontario, common law marriage requires 3 years of cohabitation, and doesn't give rights to property (which remains separate). I'd say in your situation you can still file as single, but I'd suggest asking your tax accountant to be sure. "If you pay her rent, how do you differ from a tenant in the eyes of the law? I ask this to show that you are in a business relationship first and foremost. If you don't want to file jointly, there is nothing compelling about your situation to force it. (Grant you, in most countries, there is a benefit to filing jointly) but here, I would argue it would be difficult to make the case. There are, to the best of my knowledge, no laws barring opposite sex landlord-tenant rental situations.  Furthermore, there are no laws barring romantic relationships amongst landlords and tenants.  Indeed, you would need to prove your relationship in some fashion for it to even be considered. In establishing a date of separation from my soon-to-be-ex-wife, for example, I merely needed to prove that we were not ""presenting ourselves as husband and wife.""  Once I showed that we didn't sit together at church and that she was attending parties I wasn't, that was sufficient. Proving you are in a relationship is actually a lot harder than proving you're not."
Reducing the lowest tax bracket to zero from ten, and the next one to twelve from fifteen, is a tax cut for the one percent?  As someone on the cusp of one percent, I'd be paying more under Trump's plan.  Fortunately I'm getting married and my wife doesn't make as much as me so when we file together we'll still get a break.  It's pretty sick how deficit spending only hurts the lower class and helps the one percent when there's a republican on office.  It's also pretty sick how the author's hypothetical spending cuts are to welfare, as if there's nowhere else in the budget that could be cut.   The article is partisan nonsense.  The tax cuts are directly to lower and middle class only.    True, there are massive corporate tax cuts, but any individual getting money from a corporation is paying income tax on it.  All a corporate tax does is reduce the amount of money the corporation has to invest in itself and its employees. First, the SSN isn't an issue. She will need to apply for an ITIN together with tax filing, in order to file taxes as Married Filing Jointly anyway. I think you (or both of you in the joint case) probably qualify for the Foreign Earned Income Exclusion, if you've been outside the US for almost the whole year, in which cases both of you should have all of your income excluded anyway, so I'm not sure why you're getting that one is better. As for Self-Employment Tax, I suspect that she doesn't have to pay it in either case, because there is a sentence in your linked page for Nonresident Spouse Treated as a Resident that says However, you may still be treated as a nonresident alien for the   purpose of withholding Social Security and Medicare tax. and since Self-Employment Tax is just Social Security and Medicare tax in another form, she shouldn't have to pay it if treated as resident, if she didn't have to pay it as nonresident. From the law, I believe Nonresident Spouse Treated as a Resident is described in IRC 6013(g), which says the person is treated as a resident for the purposes of chapters 1 and 24, but self-employment tax is from chapter 2, so I don't think self-employment tax is affected by this election. I have researched this question extensively in previous years as we have notoriously high taxes in California, while neighboring a state that has zero corporate income tax and personal income tax. Many have attempted pull a fast one on the California taxation authorities, the Franchise Tax Board, by incorporating in Nevada or attempting to declare full-year residence in the Silver State. This is basically just asking for an audit, however.  California religiously examines taxpayers with any evidence of having presence in California. If they deem you to be a resident in California, and they likely will based on the fact that you live in California (physical presence), you will be subject to taxation on  your worldwide income. You could incorporate in Nevada or Bangladesh, and California will still levy its taxation on any business income (Single Member LLCs are disregarded as separate corporate entities, but still taxed at ordinary income rates on the personal income tax basis). To make things worse, if California examines your Single Member LLC and finds that it is doing business in California, based on the fact that its sole owner is based in California all year long, you could feasibly end up with additional penalties for having neglected to file your LLC in California (California LLCs are considered domestic, and only file in California unless they wish to do business in other states; Nevada LLCs are considered foreign to California, requiring the owner to file a domestic LLC organization in Nevada and then a foreign LLC organization in California, which still gets hit with the minimum $800 franchise fee because it is a foreign LLC doing business in California).  Evading any filing responsibility in California is not advisable. FTB consistently researches LLCs, S-Corporations and the like to determine whether they've been organized out-of-state but still principally operated in California, thus having a tax nexus with California and the subsequent requirement to be filed in California and taxed by California. No one likes paying taxes, and no one wants to get hit with franchise fees, especially when one is starting a new venture and that minimum $800 assessment seems excessive (in other words, you could have a company that earns nothing, zero, zip, nada, and still has to pay the $800 minimum fee), but the consequences of shirking tax laws and filing requirements will make the franchise fee seem trivial in comparison.  If you're committed to living in California and desire to organize an LLC or S-Corp, you must file with the state of California, either as a domestic corporation/LLC or foreign corporation/LLC doing business in California. The only alternatives are being a sole proprietor (unincorporated), or leaving the state of California altogether. Not what you wanted to hear I'm sure, but that's the law. "From what you've described, your spouse is a non-resident alien for US tax purposes. You have two choices: Use the Nonresident Spouse Treated As Resident election and file as Married Filing Jointly. Since your spouse doesn't have, and doesn't currently qualify for, an SSN, he/she will need to apply for an ITIN together with the tax filing. Note that by becoming a resident alien, your spouse's worldwide income the whole year would be subject to US taxes, and would need to be reported on your joint tax filing, though he/she will be able to use the Foreign Earned Income Exclusion to exclude $100k of her foreign earned income, since he/she will have been out of the US for 330 days in a 12-month period. Or, file as Married Filing Separately. You write ""NRA"" for your spouse's SSN on your tax return. As a nonresident alien, if your spouse doesn't have any US income, he/she doesn't have to file a US tax return, and doesn't need to apply for an ITIN. Which one is better is up to you to figure out." "I believe you have to file a tax return, because state tax refund is considered income effectively connected with US trade or business, and the 1040NR instructions section ""Who Must File"" includes people who were engaged in trade or business in the US and had a gross income. You won't end up having to pay any taxes as the income is less than your personal exemption of $4050." You need to report your accounts, not other persons. However, if you have a joint account with another person - it is your account, jointly. So the joint account has to be reported, your girlfriend's personal accounts - not (unless the money there is yours or you have signature authority, of course). For a joint account - you need to report who are the joint holders, yes. "The Form 1040 (U.S. tax return form) Instructions has a section called ""Do You Have To File?"".  Below a certain income, you are not required to file a tax return and pay any tax.  This amount of income at which you are required to file depends on several things, including your dependency status (you are a dependent of your parents), your marital status, and other factors.  The instructions have charts that show what these numbers are.  You would fall under Chart B. Assuming that you are under age 65, unmarried, and not blind, you only have to file when you reach the following conditions: Your unearned income was over $1,050. Your earned income was over $6,300. Your gross income was more than the larger of— $1,050, or Your earned income (up to $5,950) plus $350. (Note: Income from YouTube would count as ""earned income"" for the purposes above.) However, if you are producing your own videos and receiving revenue from them, you are technically self-employed.  This means that the conditions from Chart C also apply, which state: You must file a return if any of the five conditions below apply for 2015. As a self-employed person, you can deduct business expenses (expenses that you incur in producing your product, which is this case is your videos).  Once your revenue minus your expenses reach $400, you will need to file an income tax return." Both states will want to tax you. Your tax home is where you maintain a domicile, are registered to vote, etc. and you will probably want to keep this as MA since you state that MA is your permanent residence and you are staying in a rented place in PA. But be careful about voter registration; that is one of the items that can be used to determine your state of residence.  OK, so if you and your spouse are MA residents,  you should file jointly as residents in MA and as nonresidents in PA. Do the calculations on the nonresident return first, and then the calculations on the resident  return. Typically, on a nonresident tax return, the calculations are effectively the following: Report all your income (usually AGI from the Federal return).  Call this $X. Compute the PA state tax due on $X.  Note that you follow the rules for nonresidents in doing this, not the calculations used by PA residents. Call the amount of tax you computed as $Y. What part of the total income $X is attributable to PA sources? If this amount is $Z, then you owe PA $Y times (Z/X). On the resident return in MA, you will likely get some credit for the taxes paid to PA, and this will reduce your MA tax burden. Usually the maximum credit is limited to the lesser of actual tax paid to PA and what you would have had to pay MA for the same income. As far as withholding is concerned, your employer in PA will withhold PA taxes as if you are a PA resident, but you can adjust the amount via the PA equivalent of IRS Form W4 so as to account for any additional  tax that might be due because you will be filing as a nonresident.  Else you can pay estimated taxes via the PA equivalent of IRS Form 1040ES. Similarly, your wife can adjust her withholding to account for the MA taxes that you will owe on the joint income, or you can pay estimated taxes to MA too. Note that it is unlikely that your employer in Pennsylvania will withhold  Massachusetts taxes (and send them to Massachusetts) for you, e.g. if it is a ma-and-pa store, but there may be special deals available if  your employer does business in both states, i.e. is a MA-and-PA store.
