Should I file a change of address with the IRS?
The most important thing to do when moving is to change your address with the post office. This will forward most mail for a year, and even automatically send change of address notices to many businesses that send mail to you. If you do this, and the IRS needs to send you something over the next year, you'll get it.  The IRS does have a procedure for changing your address, and you would want to do this if you are expecting something from the IRS and are unable to do a change of address with the post office for some reason. But if you do forward your mail and you aren't expecting a refund check, I don't think it is necessary. The IRS will get your new address when you file your return next year.
You put your Michigan address. The incorporation address is of no concern for the IRS, they couldn't care less where you're incorporated - it has no effect on your tax liability. The address is used when audited, and the IRS expects you to give the address where the records are (i.e.: where the business, aka you, is physically located). "If the IRS changes your return in any way (including math errors) - they send a letter explaining the change and the reasons for it. You should read that letter, it will answer your question (Usually its a CP12 notice). If you didn't receive it - you can call them and ask to resend it (they're unlikely to answer over the phone, but you can try asking). I'm confused by your using the word ""estimate"". Your tax return is not supposed to be estimate, it supposed to be precise. Why are you considering your tax return ""estimate""? If your filed tax return shows refund of $X and you received $X+$180 - then as I said, a letter of explanation from the IRS is due. If you don't know what the refund amount on your return is and you're trying to ""estimate"" it now - you better get a copy of that return." You proceed with a proper legal advice. You should not ignore IRS letters. You should have taken your chances in trying to reach a compromise with them, but that ship has likely sailed already. You might want to consider bankruptcy. Ask your parents for a couple of hundreds of dollars to pay for a legal consultation with a lawyer and a CPA and proceed from there. In how much trouble can I get exactly if the IRS finds out? I   understand that there's a 6 year statute of limitations on criminal   charges and no limitation at all on fraud. Is this considered fraud?   I'm assuming not. There's no statute of limitations for fraud (which is a criminal charge). The statute of limitations is for failure to report income which is not fraud. In your case, since you willingly decided to not report it knowingly that you should, it can most definitely account for fraud, so I wouldn't count on statute of limitations in this case. I should amend my taxes for those years That would be the easiest way to go. would the IRS go all the way and file criminal charges considering the amount of money I owe They have the legal right to, and if you do get caught - likely they will. Easy money for them, since you obviously have income and can pay all the fines and penalties. Practically speaking, what's the worst case scenario? Theoretically - can be jail as well. Being charged in a criminal court, even if the eventual punishment is just a penalty, is a punishment of its own. You'll have troubles finding jobs, passing security checks, getting loans approved, etc. For $3200, when you're in 25% bracket as an individual for years, I'd say not worth it. "Buried on the IRS web site is the ""Fillable Forms Error Search Tool"". Rather than including an explanation of errors in the rejection email itself, you're expected to copy and paste the error email into this form, which gives more details about what's wrong. (Don't blame me; I didn't design it.) If I copy your error message in, here's the response I get: There is an error with the “primary taxpayer’s Date of Birth” in Step 2 Section 4.  The date of birth that was entered does not match IRS records. Make sure you enter the correct birth date, in the correct format, in the correct space. Scroll down, and enter the current date (“Today’s date”).  Today’s date is the day you intend to e-file the return again. Also, if you are making an electronic payment you must re-date that section. E-File your return. You say that you've already checked your birthday, so I don't know as this is particularly helpful. If you're confident that it's correct and in the right place, I think your next step needs to be contacting the IRS directly. They have a link at the bottom of the error lookup response on how to contact them specifically about their solution not working, or you could try contacting your local IRS office or giving them a call." I'm not an attorney, nor am I a licensed tax adviser. I suggest you talk to these two types of professionals. From my limited knowledge, without proper documentation/organization, I can't see how the IRS/State will not consider this as a rent payment. The mortgage responsibility is of the person signing the mortgage contract, and you're under no obligation to pay that person anything. Had you not lived at the property, you might argue that it was a gift (although I'm not sure if it would stand), but since you do live in the property - it is quite obviously a rent payment. Putting your name on the deed may mitigate this slightly but I'm not sure how much - since you're still not obligated to pay the mortgage. However this is probably moot since it is unlikely for a bank to give a mortgage on a property to person A when it is also owned by a person B, without that person B being side to the mortgage contract. "The wire is probably the quick way to go. There may be a lower cost method through an international bank like Citi or HSBC. If you are a US resident or have a ""substantial presence"" in the United States, the IRS may be interested in the origins of your money." "I'm mostly guessing based on existing documentation, and have no direct experience, so take this with a pinch of salt. My best understanding is that you need to file Form 843. The instructions for the form say that it can be used to request: A refund or abatement of a penalty or addition to tax due to    reasonable cause or other reason (other than erroneous written    advice provided by the IRS) allowed under the law. The ""reasonable cause"" here is a good-faith confusion about what Line 79 of the form was referring to. In Form 843, the IRC Section Code you should enter is 6654 (estimated tax). For more, see the IRC Section 6654 (note, however, that if you already received a CP14 notice from the IRS, you should cross-check that this section code is listed on the notice under the part that covers the estimated tax penalty). If your request is accepted, the IRS should issue you Notice 746, item 17 Penalty Removed: You can get more general information about the tax collection process, and how to challenge it, from the pages linked from Understanding your CP14 Notice" Why not just leave it as is and register as foreign entity in New Mexico? You won't avoid the gross receipts tax, but other than that - everything stays as is. Unless Illinois has some taxes that you would otherwise not pay - just leave it there. It will not affect your tax bracket so long as he files his taxes.   It will not affect your credit negatively so long as the joint account takes out no debts.  If it does take out debts, then someone would need to pay them to avoid negative credit.  Ideally debts should take signatures from both of you (ask the bank).   The IRS will not automatically assume that the only reason that two people might have a joint account is illegal activities.   If he withdraws money from the account in such a way to cause an overdraft, you might be responsible for it.  However, it sounds like he isn't supposed to be withdrawing money from that account.  So that's a potential problem but not a guaranteed problem.  Make sure that you have the power to close the account without him (so if you break up later, you can take your name off unilaterally).  Realize that you might have to pay a little to close the account if he overdraws it.  If possible, have the bank refuse overdrafts.   Consider a savings account rather than a checking account.  The rules may better fit what you want to do.  In particular, if you are limited to transfers, that's safer than checks.  Schedule a time to talk to someone at the bank about the account.  Ask them to leave plenty of time because you have questions.  Explain what you want and let them tell you how to structure the account. I suggest you talk to a New York-licensed tax adviser (EA or NY-licensed CPA). New York is very aggressive when it comes to residency determination, and given your facts and circumstances you may end up being considered NY resident despite relocating to Florida. If you maintain a studio in NY, I'd say 99% chance is that you remain NY resident for the whole year (but verify with a professional). "Ditto @GradeEhBacon, but let me add a couple of comments: But more relevantly: GradeEhBacon mentioned transaction costs. Yes. Many tax shelters require setting up accounts, doing paperwork, etc. Often you have to get a lawyer or accountant to do this right. If the tax shelter could save you $1 million a year in taxes, it makes sense to pay a lawyer $10,000 to set it up right. If it could save you $100 a year in taxes, paying $10,000 to set it up would be foolish. In some cases the tax savings would be so small that it wouldn't be worth the investment of spending $20 on a FedEx package to ship the paperwork. Inconvenience. Arguably this is a special case of transaction costs: the cost of your time. Suppose I knew that a certain tax shelter would save me $100 a year in taxes, but it would take me 20 hours a year to do the paperwork or whatever to manage it. I probably wouldn't bother, because my free time is worth more than $5 an hour to me. If the payoff was bigger or if I was poorer, I might be willing. Complexity. Perhaps a special case of 3. If the rules to manage the tax shelter are complicated, it may not be worth the trouble. You have to spend a bunch of time, and if you do it wrong, you may get audited and slapped with fines and penalties. Even if you do it right, a shelter might increase your chance of being audited, and thus create uncertainty and anxiety. I've never intentionally cheated on my taxes, but every year when I do my taxes I worry, What if I make an honest mistake but the government decides that it's attempted fraud and nails me to the wall? Qualification. Again, as others have noted, tax shelters aren't generally, ""if you fill out this form and check box (d) you get 50% off on your taxes"". The shelters exist because the government decided that it would be unfair to impose taxes in this particular situation, or that giving a tax break encourages investment, or some other worthy goal. (Sometimes that worthy goal is ""pay off my campaign contributors"", but that's another subject.) The rules may have unintended loopholes, but any truly gaping ones tend to get plugged. So if, say, they say that you get a special tax break for investing in medical research, you can't just declare that your cigarette and whiskey purchases are medical research and claim the tax break. Or you talked about off-shore tax havens. The idea here is that the US government cannot tax income earned in another country and that has never even entered the US. If you make $10 in France and deposit it in a French bank account and spend it in France, the US can't tax that. So American companies sometimes set up bank accounts outside the US to hold income earned outside the US, so they don't have to bring it into the US and pay the high US tax rate. (US corporate taxes are now the highest of any industrialized country.) You could, I suppose, open an account in the Caymans and deposit the income you earned from your US job there. But if the money was earned in the US, working at a factory or office in the US,  by a person living in the US, the IRS is not going to accept that this is foreign income." "Did it show just your address, or was your name on it as well?   You didn't share how long you've lived at the address either, so it makes me wonder whether a former tenant is the one who filed that paperwork.  It's also possible that someone used your address when making a filing.  Whether that was deliberate or accidental is hard to discern, as is their intent if it was intentional. It could be accidental -- someone picked ""CA"" for California when they meant to pick ""CO"" for Colorado or ""CT"" for Connecticut...These things do happen.  It can't make you feel any better about the situation though. You should be able to go online to the California Secretary of State's website (here) and look up everything filed by the LLC with the state.  That will show who the founders were and everything else that is a matter of public record on the LLC.  At the very least, you can obtain the registered agent's name and address for the LLC, which you can then use to contact them and ask why your address is listed as the LLC's business address. Once you have that info, you can then contact the Secretary of State and tell them it isn't you so they can do whatever is necessary to correct this. This doesn't sound like a difficult matter to clear up, but it's important to do your homework first and gather as much information as you can before you call the state.  Answering ""I don't know"" won't get you very far with them compared to having the best answers you can about where the mistake started. I hope this helps. Good luck!" I am currently dealing with the same issue of having a 1099 reported to the wrong person.  I applied for the square account for my son's business but used my information, which I realized now was a BIG mistake.  I did contact Square by email yesterday, which was Saturday, not expecting to hear from them until Monday, or possibly not at all (wasn't hearing a lot of good things about Square's customer service).  She was most helpful and while the issue isn't completely taken care of, I do feel better about it.  She just had me update the taxpayer information number which then updated the 1099 form. "If you are a telecommuter and in good terms with your employer, then all you need is contact your employer and explain your situation. Ask them for a short letter that indicates: ""1. they require you to work from a privately rented office (or from a home office for those who prefer working from home), 2. this is one of the terms of your employment, and, 3. they will not reimburse you for this expense."" With this letter in your hand, you satisify both the ""convenience of employer"" test AND the deduction of the rent for your private office as a unreimbursed employee expense.  The IRS cannot expect your employer to open an office branch in your city just for your sake, nor can they expect you to commute to your employer's city for work, which is an impossiblity considering the distance. Additionally, the IRS cannot ""force"" telecommuters to work from home. The key is to get a letter from your employer. You'd be surprised how easily they are willing to write such letter for you."
