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.
"Hearing somewhere is a level or two worse than ""my friend told me.""  You need to do some planning to forecast your full year income and tax bill. In general, you should be filing a quarterly form and tax payment. You'll still reconcile the year with an April filing, but if you are looking to save up to pay a huge bill next year, you are looking at the potential of a penalty for under-withholding.  The instructions and payment coupons are available at the IRS site.  At this point I'm required to offer the following advice - If you are making enough money that this even concerns you, you should consider starting to save for the future. A Solo-401(k) or IRA, or both. Read more on these two accounts and ask separate questions, if you'd like." The obligation is contractual, so you need to read the contract to answer your question. However, since you paid for the service provided, I see no way they can force you buy any other service from them. They cannot file your tax returns without your explicit consent (on a form dedicated to that, dated and having the numbers matching the return filed - not something you can sign before the actual return is ready). Worst case they can claim you owe them more money, but since you paid for the services provided, I can't see how they can have that stand in court as well. Bottom line - even if the contract has such an obligation, I cannot see how it can be enforced. As to the mistake they noted... I wouldn't rely on H&R Block advice in any matter. Very likely, the person you were talking to was not even licensed to provide tax advice. You're lucky if the person has passed CRTP exams (in California they're legally required), but I seriously doubt their clerks are EAs or CPAs (the only designations other than a lawyer legally allowed to provide tax advice). Tax preparers (CRTPs included) are only allowed to provide advice pertaining to the preparation of the tax return they're currently engaged to prepare. Claiming income is sourced or not sourced in NY is borderline, IMHO. If they got it wrong (and to me it sounds as they did) you can sue them for damages. If your situation is tricky and it is too late to get an appointment with a proper adviser - file an extension (form 4868) and deal with it after the April busy season. You can file a revised W-4 with your employer claiming more allowances than you do now. More allowances means less Federal tax and (if applicable and likely with a separate form) less state tax. This doesn't affect social security and Medicare with holding, though.  That being said, US taxes are on a pay-as-you-go system. If the IRS determines that you're claiming more allowances than you're eligible for and not paying the proper taxes throughout the year, they will hit you with an underpayment penalty fee, which would likely negate the benefits of keeping that money in the first place. This is why independent contractors and self-employed people pay quarterly or estimated taxes. Depending on the employer, they may require proof of the allowances for adjustment before they accept the revised W-4. File a 2nd amended return that corrects the mistake I made on the 1st amended return This. Pay the $500 before April 27th and try to get it back later This. Your best bet is going to be contacting TaxAct directly for their information. If you do enter your spouses information and choose to purchase their deluxe product, I would think you might end up paying for the second efile. I have used their deluxe version for many years now, but choose it mostly because of the free state efiling and not for the ability to determine whether or not to file separately.  In my case, it makes sense to file jointly and not file separately.   The deluxe version allows you to portion out your deductions and see which method of filing gives you the lowest total tax bill. Here's the link directly to TaxAct's support: https://www.taxact.com/tsupport/support_request.asp The IRS allows filers to attach a statement explaining the reason for late filing.  I have had clients do this in the past, and there has never been an issue (not that that guarantees anything, but is still good to know). Generally, the IRS is much more lenient when a taxpayer voluntarily complies with a filing requirement, even if it's late, than if they figure it out themselves and send a notice. Since you both are members of the LLC - it is not a single-member LLC, thus you have to file the tax return on behalf of the LLC (I'm guessing you didn't elect corporate treatment, so you would be filing 1065, which is the default). You need to file form 4868 on behalf of yourselves as individuals, and form 7004 on behalf of the LLC as the partnership. Since the LLC is disregarded (unless you explicitly chose it not to be, which seems not to be the case) the taxes will in fact flow to your individual return(s), but the LLC will have to file the informational return on form 1065 and distribute K-1 forms to each of you. So you wouldn't pay additional estimated taxes with the extension, as you don't pay any taxes with the form 1065 itself. If you need a help understanding all that and filling the forms - do talk to a professional (EA or CPA licensed in your state). Also, reconsider not sending any payment. I suggest sending $1 with the extension form even if you expect a refund. California is very aggressive when it comes to determining residency. While you have a legitimate defense, I suggest talking with a California-licensed CPA or EA practicing in California, which are experienced in dealing with the FTB residency audits. It matters because that is the requirement for the 83(b) selection to be valid. Since the context is 83(b) election, I assume you got stocks/options as compensation and didn't pay for them the FMV, thus it should have been included in your income for that year. If you didn't include the election letter - I can only guess that you also didn't include the income. Hence - you lost your election. If you did include the income and paid the tax accordingly, or if no tax was due (you actually paid the FMV), you may try amending the return and attaching the letter, but I'd suggest talking to a professional before doing it on your own. Make sure to keep a proof (USPS certified mailing receipt) of mailing the letter within the 30 days window. Based on these dates in your question: Going back over my records, I was able to recall the following: Maryland realized recently that on the 2009 Federal 1040 Form you stated that on December 31 2009 you liven in Maryland. They are wondering where the state tax form is. DC, MD and VA due to reciprocity collect income tax based on where you live not where you work. So when you moved in August 2009 and again in August 2010 you needed to file new state versions of the W4.  The fact you did or didn't submit to your employer a correct state W-4 is not directly related, because you would owe the tax regardless. The W-4 just makes sure that something close to the correct amounts are withheld and sent to the appropriate state capital. I seem to remember something about not having to pay Maryland state   taxes since I not only lived in the state for less than 6 months but   also did not work in the state. The reciprocity between DC, MD and VA says that Maryland gets the money because that is where you lived. The last time I had to do a part year the law was that they would forgive a half a month. In other words if you move in late December or early January you could ignore that small time period and avoid having to file in two states. In some cases people argue that some short term moves were never meant to be permanent. You might be able to claim that except the fact that your 2009 federal tax form you most likely claimed you lived in Maryland.  The next issue is time and money. If Maryland says you  owe them money for that time period, and if they still have the ability to force you to pay it; This is where the issue of correct state W-4 comes in.  If the money during the period you lived in Maryland was sent to Virginia, you should have had that money refunded by Richmond in the spring of 2010. But if there was no W-4 filed with your employer that would mean that Maryland didn't get any money for 2009. If you didn't tell Richmond you moved in 2009 they may not have refunded everything because they thought you lived there all year. Because of the time that has passed it may be too late to fix your Virginia filing, so they may not refund you excess payment to them. Maryland is interested in calculating how much you should have paid them in 2009. They are only looking at what you told the feds you made, and they may be assuming that you lived there the whole year. But until you file correctly that have no ability to calculate what you really owe. You need professional advice. You need to know what they can and can't collect. You also need to know what you can and can't get back from Richmond. And since it also may impact your filings for 2010 you will want to get that resolved at the same time. I'd be surprised if this ended in a materially-damaging final settlement. It may take more than 5 years to resolve, unless a smoking gun is produced. If PWC and outside counsel really issued written opinions, it could get a lot messier. Especially when we tip over into another recession, the IRS will come under intense Congressional pressure to cut a nominal deal. To be on the safe side - you'll want to get the full invoice. You don't need to actually print them, you can save it as a PDF and make sure to make your own backups once in a while. Only actually print them when the IRS asks you to kill some trees and send them a paper response, and even then you can talk to the agent in charge and check if you can email the digital file instead. The IRS won't ask for this when you file your taxes, they will only ask for this if you're under audit and they will want to actually validate the numbers on your return. You'll know when you're under audit, and who is the auditor (the agent in charge of your case). You'll also want to have some representation when that happens. 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. If you took advantage of options like a home buyers plan (HBP) you definitely need to file since you must designate how much of the plan to repay.  Your employer does not know about what you do with your money so cannot take this into account for the withheld taxes.  If you do not report repayment of the HBP it will be treated as a withdrawal from your RRSP i.e. additional income for that tax year. "It's not quite as bad as the comments indicate. Form 1040ES has been available since January (and IME has been similarly for all past years). It mostly uses the prior year (currently 2016) as the basis, but it does have the updated (2017) figures for items that are automatically adjusted for inflation: bracket points (and thus filing threshhold), standard deductions, Social Security cap, and maybe another one or two I missed.  The forms making up the actual return cannot be prepared very far in advance because, as commented, Congress frequently makes changes to tax law well after the year begins, and in some cases right up to Dec. 31. The IRS must start preparing forms and pubs -- and equally important, setting the specifications for software providers like Intuit (TurboTax) and H&RBlock -- several months ahead in order to not seriously delay filing season, and with it refunds, which nearly everyone in the country considers (at least publicly) to be worse than World War Three and the destruction of the Earth by rogue asteroids. I have 1040 series from the last 4 years still on my computer, and the download dates mostly range from late September to mid January. Although one outlier shows the range of possibility: 2013 form 1040 and Schedule A were tweaked in April 2014 because Congress passed a law allowing charitable contributions for Typhoon Haiyan to be deducted in the prior year. Substantive, but relatively minor, changes happen every year, including many that keep recurring like the special (pre-AGI) teacher supplies deduction (""will they or won't they?""), section 179 expensing (changes slightly almost every year), and formerly the IRA-direct-to-charity option (finally made permanent last year).  As commented, the current Congress and President were elected on a platform with tax reform as an important element, and they are talking even more intensely than before about doing it, although whether they will actually do anything this year is still uncertain. However, if major reform is done it will almost certainly apply to future years only, and likely only start after a lag of some months to a year. They know it causes chaos for businesses and households alike to upend without advance warning the assumptions built in to current budgets and plans -- and IME as a political matter something that is enacted now and effective fairly soon but not now is just as good (but I think that part is offtopic)."
