U.S. nonresident alien: Is my state tax refund taxable?
Federal income tax refunds received during 2016 are not taxable income for 2016 (or any other year) on either the Federal or the State tax return. The State income tax refund for 2015 received during 2016 is not taxable income on the State tax return for 2016. It is taxable income on the Federal tax return for 2016 only to the extent that you received a tax benefit (reduction in Federal income tax due) from deducting State income tax as an Itemized Deduction on your 2015 Federal return. If you didn't deduct State income tax because you deducted State sales tax instead, then the State income tax refund is not taxable income on the Federal tax return.
"Is all interest on a first time home deductible on taxes? What does   that even mean? If I pay $14,000 in taxes will My taxes be $14,000   less. Will my taxable income by that much less? If you use the standard deduction in the US (assuming United States), you will have 0 benefit from a mortgage.   If you itemize deductions, then your interest paid (not principal) and your property tax paid is deductible and reduces your income for tax purposes.  If your marginal tax rate is 25% and you pay $10000 in interest and property tax, then when you file your taxes, you'll owe (or get a refund) of $2500 (marginal tax rate * (amount of interest + property tax)). I have heard the term ""The equity on your home is like a bank"". What   does that mean? I suppose I could borrow using the equity in my home   as collateral? If you pay an extra $500 to your mortgage, then your equity in your house goes up by $500 as well.   When you pay down the principal by $500 on a car loan (depreciating asset) you end up with less than $500 in value in the car because the car's value is going down.   When you do the same in an appreciating asset, you still have that money available to you though you either need to sell or get a loan to use that money. Are there any other general benefits that would drive me from paying   $800 in rent, to owning a house? There are several other benefits. These are a few of the positives, but know that there are many negatives to home ownership and the cost of real estate transactions usually dictate that buying doesn't make sense until you want to stay put for 5-7 years.   A shorter duration than that usually are better served by renting.  The amount of maintenance on a house you own is almost always under estimated by new home owners." "If you are a permanent resident (and it wasn't taken away or abandoned), then you are a resident alien for U.S. tax purposes. (One of the two tests for being a resident alien is the ""green card test"".) Being a resident alien means all your worldwide income is subject to U.S. taxes, regardless of where you live or work. That doesn't necessarily mean you need to actually pay taxes on your income again if you've already paid it -- you may be able to use the Foreign Tax Credit to reduce your taxes by the amount already paid to a foreign government -- but you need to report it on U.S. tax forms just like income from the U.S., and you can then apply any tax credits that you may qualify for. As a resident alien, you file taxes using Form 1040. You are required to file taxes if your income for a particular year is above a certain threshold. This threshold is described in the first few pages of the 1040 instructions for each year. For 2013, for Single filing status under 65, it is $10000. The only way you can legally not file is if your income the whole year was below this amount. You should go back and file taxes if you were required to but failed to. Having filed taxes when required is very important if you want to naturalize later on. It is also one component of demonstrating you're maintaining residency in the U.S., which you're required to do as a permanent resident being outside the U.S. for a long time, or else you'll lose your permanent residency. (Even filing taxes might not be enough, as your description of your presence in the U.S. shows you only go there for brief periods each year, not really living there. You're lucky you haven't lost your green card already; any time you go there you run a great risk of them noticing and taking it away.)" Since you were a nonresident alien student on F-1 visa then you will be considered engaged in a trade or business in the USA. You must file Form 1040NR.  Here is the detailed instruction by IRS - http://www.irs.gov/Individuals/International-Taxpayers/Taxation-of-Nonresident-Aliens "Here is the way I would estimate your taxes.  Remember that a bi-weekly paycheck means that you get 26 paychecks per year. If the $1000 federal refund is too much for you, you can decrease your withholding to bring your refund down.  This can be done by increasing your exemptions claimed on your W-4.  See ""How can I adjust tax withholding so that I don't get a large Tax Refund?"" for more details. However, keep in mind that your state withholding is perfect right now, and if you increase your exemptions, you will likely owe tax to the state, unless you increase your state withholding at the same time." Should I have a W-2 re-issued? A W-2 can be corrected and a new copy will be filed with the IRS if your employer incorrectly reported your income and withholding on a W-2 that they issued. In this case, though the employer didn't withhold those taxes, they should not reissue the W-2 unless they plan to pay your portion of the payroll taxes that were not withheld. (If they paid your share of the taxes, that would increase your gross income.) Who pays for the FICA I should have paid last year? Both you and your employer owe 7.65% each for FICA taxes. By law your employer is required to pay their half and you are required to pay your half. Both you and your employer owe additional taxes because of this mistake. Your other questions assume that your employer will pay your portion of the taxes withheld. You employer could decide to do that, but this also assumes that it was your employer's fault that the mistakes were made. If you transitioned to resident alien but did not inform your employer, how is that your employer's fault? "The answer to your first question is true. No tax on withdrawls. Under these circumstances, the withdrawl is ""qualified"". To your second question, as long as the withdrawl is qualified, it is not taxed, regardless of your additional income. http://www.investopedia.com/articles/retirement/03/030403.asp?lgl=rira-baseline-vertical has a very comprehensive, plain English, description of the IRS rules (as of today, anyway)." Having a large state return also means that there is a potential income tax liability created at the federal level for the following year, as the situation resulted from the deduction of more on one's federal return than should have been deducted. The state refund is treated as federal income in the year it is refunded. http://blog.turbotax.intuit.com/tax-tips/is-my-state-tax-refund-taxable-and-why-90/ You need to fill out form 8606.  It's not taxable, but you still need to report it
