Is the address on 1040 and MD resident 502 my previous address in 2013 or my current address?
No, always give the most current address information to the IRS, not least because they will use this address to send you important communications, such as refund checks or notices of deficiency. Per the 1040 Instructions, you should put in your address, with no mention of past addresses.  Moreover, if you will change addresses after filing, the IRS has provided Form 8822 to notify them of the new address.  There is a similar Form 8822-B for business addresses. They will use your Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or Employer Identification Number (EIN) to track who you are.  There's no point to purposely giving an invalid address, and in fact it's technically illegal since you will sign and certify the return as true and accurate to the best of your knowledge.
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. I did the reverse several years ago, moving from NH to MA. You will need to file Form 1-NR/PY for 2017, reporting MA income as a part-year residence. I assume you will need to report the April capital gain on your MA tax return, as you incurred the gain while a MA resident. (I am not a lawyer or tax professional, so I don't want to state anything about this as a fact, but I would be very surprised if moving after you incurred the gain would have any affect on where you report it.) While I agree with keshlam@ that the gym had no reason (or right) to ask for your SSN, giving false SSN to obtain credit or services (including gym membership) may be considered a crime. While courts disagree on whether you can be charged with identity theft in this scenario, you may very well be charged with fraud, and if State lines are crossed (which in case of store cards is likely the case) - it would be a Federal felony charge. Other than criminal persecution, obviously not paying your debt will affect your credit report. Since you provided false identity information, the negative report may not be matched to you right away, but it may eventually. In the case the lender discovers later that you materially misrepresented information on your mortgage application - they may call on your loan and either demand repayment in full at once or foreclose on you. Also, material misrepresentation of facts on loan application is also a criminal fraud. Again, if State lines are crossed (which in most cases, with mortgages they are), it becomes a Federal wire fraud case. On mortgage application you're required to disclose your debts, and that includes lines of credits (store cards and credit cards are the same thing) and unpaid debts (like your gym membership, if its in collection). I heard from someone that since my friends are moving money to my account, I'm liable to be taxed by the IRS  Not completely true. If there are large deposits in your account, you may be asked for clarification from IRS. If there is a reasonable justification; in your case the agreement that you are sharing the apartment, the lease deed has all the 3 names, there is explicit mention in lease about how funds are transferred. Note at times the audit maybe in future for quite a bit of past. Hence you would need to keep the record for quite some time. Alternative arrangements like opening a joint account and making payments from that account may make it easier from record keeping point of view. If it is your primary residence and you lived there continuously and for more than 2 years out of the last 5 - then you can exclude the gain under the IRC Sec. 121. In this case, you'll pay no taxes on your gain. If the property has been a rental or you haven't lived there long enough, the rules become more complicated but you may still be able to exclude some portion of the gain, even all of it, depends on the situation. So it doesn't look like 1031 exchange is good for you here, you don't want to carry excluded gain - you want to recognize it and get the tax benefit. However, refinancing after purchase with cash-out money affects the deductability of the loan interest. You can only deduct interest on money used to buy, not cash-out portion. I believe there's a period (60 days IIRC) during which you can do the cash-out refinance and still count it as purchase money, but check with a licensed tax advier (EA/CPA licensed in your State). It is also possible that the settlement company didn't tell the local government where to send the new tax bill. This would worry me because what else was missed regarding filing the proper documents with the lenders and the local government. It could also be a problem with the local government. Contact the settlement company or your attorney to get the issue resolved. If you owe the money you want to know; if the new owner owes the money they don't want to face a tax lien because the settlement company made a mistake. Generally this is split between the parties based on the number of days each will own the home. At settlement the money should move from one party to the other based on what has been deposited into escrow and when the actual bills are due. For example the payment for the first half of the year due July 1st may be sent in June. If the settlement was in June The new owner would give money to the old owner. But if settlement was in early July Money would move the other way. I think you should consult a professional with experience in 83(b) election and dealing with the problems associated with that. The cost of the mistake can be huge, and you better make sure everything is done properly. For starters, I would look at the copy of the letter you sent to verify that you didn't write the year wrong. I know you checked it twice, but check again. Tax advisers can call a dedicated IRS help line for practitioners where someone may be able to provide more information (with your power of attorney on file), and they can also request the copy of the original letter you've sent to verify it is correct. In any case, you must attach the copy of the letter you sent to your 2014 tax return (as this is a requirement for the election to be valid). "This may be relevant: it suggests that IRS is lenient with the attachment of the form with 1040. To paraphrase: ""The ruling involved a taxpayer who timely filed the election with the IRS within 30 days of the property transfer but who did not attach a copy of the election to his or her Form 1040 for the year of the transfer.  Fortunately for the taxpayer in question, the ruling indicated that the submission of the election to the IRS within 30 days of the property transfer fulfilled the requirements for a valid election, and the failure to attach the copy to the tax return did not affect the validity of the election.  The IRS requested that the taxpayer forward a copy of the election to the IRS to be associated with the processing of the tax return. - See more at: http://www.bnncpa.com/services/employee_benefit_plans/blog/irs_rules_that_failure_to_attach_83b_election_to_form_1040_did_not_invalida#sthash.0c3h2nJY.dpuf"" If someone wants to grok the IRS ruling: http://www.irs.gov/pub/irs-wd/1405008.pdf And this is the article where I saw the above referenced. www.bnncpa.com/services/employee_benefit_plans/blog/irs_rules_that_failure_to_attach_83b_election_to_form_1040_did_not_invalida" "I have no personal knowledge of this company; I've only looked over what I found on the web.  Overall, my judgement is that Pension Benefit Information, Inc. of San Rafael, CA is likely legitimate and aboutmyletter.com is one of two sites run by them (the other being pbinfo.com). These two sites are registered to Pension Benefit Information, Inc. (aboutmyletter uses Network Solutions privacy service but gives the company name; pbinfo uses their name and San Rafael address.) They are in the BBB.  The president (of the 8 employee Co.), Susan McDonald, has testified (PDF on .gov site) before Congress about business uses of SSNs.  They made a (very schlocky) video, which has an interview with McDonald after several canned, generic, ""impressive"" introductions.  I found the interview convincing of a person actually running a small, real business of this type.  A short version is on their site, long version here. There are some queries about their legitimacy online (like this one), but I found nothing negative on them, and one somewhat positive. One article talks about the suspicions they run into when contacting participants, and has some advice.  Also, scammers are unlikely to pay the U.S. Postal Service money to send paper letters. So what are the dangers? Money or identity.  So don't pay them any fees (now or later), especially since it looks like their clients (retirement funds) pay on the other side.  As for identity information: What's in the letter?  Don't they show that they already know a bunch about you?  Old employer?  Maybe the last four digits of your SSN?  Your address (if this is not the forwarded-by-IRS type of contact letter).  Other things, maybe?  What information would you be giving up if you did respond to them fully? You could try contacting your old company directly (mentioning PBI, Inc,), although on their website PBI says you'll have to go through them.  (They probably get paid for each successful contact, and deserve it.)  Still, responding through mail or telephone to PBI seems like the reasonable thing to do." As I have worked for H&R Block I know for a fact that they record all your activity with them for future reference. If it is their opinion that you are obligated to use their service if you use some other service then this, most likely, will affect your future dealings with them.  So, ask yourself this question: is reducing their income from you this year worth never being able to deal with them again in future years? The answer to that will give you the answer to your question. "It is legal.  They're probably going to give you a 1099-MISC, which is required of businesses for many cash payments over $600 in value to all sorts of counterparties.  (Probably box 3 of 1099-MISC as is typical in ""cash for keys"" situations where one is paid to vacate early)   A 1099-MISC is not necessarily pure income, but in this case, you do have money coming in.  This money isn't a return of your security deposit or a gift. The payment could possibly be construed by you as a payment to make you whole, but the accounting for this would be on you.  This is not a typical situation for IRS reporting.   However, if you are uncomfortable with potentially explaining to the IRS how you implemented advice from strangers over the internet, the safest course is to report it all as income.  Look at it this way: you did enter into a mutual contract, where you were paid consideration to release your leasehold interests in the property." I will preface saying that I only have personal experience to go on (purchased home in KS earlier this year, and have purchased/sold a home in AR). You do not give the seller the document stating the amount you have been approved for. Your real estate agent (I recommend having one if you don't) will want to see it to make sure you will actually be able to purchase a house though. But the contract that is sent to the Seller states the total purchase price you are willing to pay and how much of that will be financed. Link to blank KS real estate contract shows what would be listed. Looks like it is from 2012 - it is similar to the one I had back in March, but not exactly the same format. "I know nothing about this stuff. Am I in trouble? You might be. If you don't file your return the IRS may ""make up"" one for you based on the (partial) information they have. Then they'll assess taxes and penalties and will go after you to pay those. Will I be hit with interest/penalties? You may if any money is owed. You may also lose the refund if you wait for too long (3 years after the due date). You may also be hit with the penalties for non-filing/late filing by your State. Not owing to IRS doesn't mean you also don't owe to the State - you can get hit with interest and late payment penalties there too. He has all my paperwork (I probably have copies... somewhere...) Should I go somewhere else and start fresh? He must return all the original paperwork you gave him. He can be disbarred if he doesn't. If you did 2013 yourself - what was significantly different in 2012 that you couldn't do yourself? If nothing - then just do it yourself and be done with it. You can buy 2012 preparation software at very deep discounts now. Otherwise - yes, go somewhere else. Busy season is over and it shouldn't be difficult to find another preparer/EA/CPA to do the work for you." Hope you figure it out.  There wouldn't be a different RFR / discount rate because you're assuming a return on parked cash - that's what it's for.  Since both situations would theoretically happen simultaneously you use the same rate unless you would do something different with cash in each instance. It looks like what you're calling a name change was registered as a merger that resulted in an exchange of stock.  If that's the case, then what you've been told is correct.  You've got one long-term sale and one short-term sale. Based a quick read of the Form 8937 that was filed, it looks like there were multiple entities involved in this event, more than one of which existed prior to it. https://www.mylan.com/-/media/mylancom/files/form%208937%20for%20mylan%20n%20v.pdf
