Washington State tax filing extension?
Washington State doesn't have a state income tax for individuals, so unless you've got a business there's nothing to file. Find out more on their website.
"Form W-9 (officially, the ""Request for Taxpayer Identification Number and Certification"") is used in the United States income tax system by a third party who must file an information return with the Internal Revenue Service (IRS). It requests the name, address, and taxpayer identification information of a taxpayer (in the form of a Social Security Number or Employer Identification Number). A W-9 is typically required when an individual is doing work, as a contractor or as an employee, for a company and will be paid more than $600 in a tax-year.  The company is required to file a W-2 or a 1099 and so requests a W-9 to get the information necessary for those forms. I cannot say if it is incompetence on the part of the accounting department or a deliberate ploy to make the refund process more onerous, but do not comply.  Politely nsist on a refund without any further information.  If the company refuses, request a charge-back from the credit-card company, file a complaint with the consumer-protection department of the state where the company is located, and write a bad review on Yelp or wherever else seems appropriate." This is a common occurrence, I know people who moved and then only remember the next spring during tax season that they never filed a new state version of a W-4. Which means for 3 or 4 months in the new year money is sent to the wrong state capital, and way too much was sent the previous year. In the spring of 2016 you should have filed a non-resident tax form with Michigan. On that form you would specify your total income numbers, your Michigan income numbers, and your other-state income numbers; with Michigan + other equal to total. That should have resulted in getting all the state taxes that were sent to Michigan returned.  It is possible that the online software is unable to complete the non-resident tax form. Not all forms and situations can be addressed by the software. So you may need to fill out paper forms. You should be able to find what you need on the state of Michigan website for 2015 Taxes. A quick read shows that you will probably need the Michigan 1040, schedule 1 and Schedule NR You may run into an issue if your license, car registration, voter registration, and other documentation point to you being a resident for the part of the year you earned that income. That means you will have to submit Form 3799 Statement to Determine State of Domicile You want to do this soon because there are deadlines that limit how far back you can files taxes. The state may also get tax information from the IRS and could decide that all your income from 2015 should have applied to them, so they will be sending you a tax bill plus penalties for failure to file. Yes. In fact, it's explicitly mentioned in Publication 590-A that you can file before making the contribution, as long as you make the contribution before the deadline. Filing before a contribution is made.    You can file your return claiming a traditional IRA contribution before the contribution is   actually made. Generally, the contribution must be made by the due   date of your return, not including extensions. She filed for 0 withholdings in her W4, so my (unprofessional) guess   was that she'd be owed money, and therefore the IRS wouldn't care much   if she didn't file her taxes.† Maybe, but doesn't she want that money back? Is she at as much risk as any other individual of being audited and   penalized to the same degree if she skips filing her taxes? Audited and penalized are not the same. She's at the same risk of being audited, and even slightly higher since the IRS got reports of her wages, but didn't get the matching report from her. They may want to ask why. But it doesn't mean she's going to be penalized for anything. Being audited doesn't mean you did something wrong. Or does the IRS tend to overlook such individuals. The IRS might want to overlook because they're the ones owning money. She cannot get a refund without filing a tax return. She'd file her taxes today if she could, but the worry is that time's   running out Filing an extension is free and it postpones the deadline to file till OCTOBER! The regulations you're talking about (TR 1.263) are going into effect starting tax year 2016, so for purchases you made last year they're (kindof...) irrelevant. Kindof, because the IRS promises to not audit those that qualify under the regulations even if they use it before it goes into effect, but it doesn't legally have to. Since the regulations are new, I suggest you talk to a licensed professional who'd explain them to you and interpret them with regards to your specific situation. From my brief read, you can expense under these rules things that you would otherwise capitalize, with the $500 limit to the invoice. Meaning, if you bought a computer paying $500, which you use 50% for your business - you can expense $250. The benefit, comparing to the Sec. 179, is that you're not limited to new items, nor are you limited to business revenue. Otherwise, it looks like the applicability is similar. As I said - talk  to a licensed tax adviser (EA/CPA licensed in your State), since these rules are new and untested, and you should probably have a professional provide guidance. I'm not such a professional. I did receive TurboTax's automatically generated confirmation of successfully completing tax filing electronically the day I did my tax on their web site. About 24 to 48 hours after you push the button at TurboTax the IRS should either confirm or reject the initial check of the tax documents. You should return to the TurboTax website to make sure the IRS has accepted the reutrn. Next review either the confirmation you received when you pushed the button or the information at the TurboTax site. It should specify when the money would be withdrawn. You were given options regarding payment method and date you want to make the payment. Many people who finish their tax paperwork early, but owe money wait until the last day to submit. Now it is possible to submit paperwork early but specify a date just before the deadline. Print out or even better save an electronic copy of the information at the TurboTax website. I have no idea how long it takes the IRS to actually pull the money from an account, once the day you specified has occurred. You have to plan as if the withdraw will happen on the exact date, but with millions of tax payers making transactions it may be delayed by a day or two. The purpose of making sure you met the safe harbor was to avoid the penalty. Having achieved that goal the tax law allows you to wait until April 15th to pay the balance. So do so.  Put enough money aside to make sure you can easily make that payment.  I was in this exact situation a few years ago. I planned my w4 to make the safe harbor, and then slept easy even though the house settlement was in May and I didn't have to make the IRS payment unti 11 months later in April. According to TurboTax, it is perfectly legal to final as an individual with zero income. But, alas, according to Entities, by the IRS, you must file as a partnership or a corporation even if you have zero income.  As for my two cents, I can only see it being advantageous for filing on expense purposes, but as you have no income, the point is mute. Hope it all goes over well as the forms are due March 15.
