Impact of EIN on taxation
"Is it possible if (After getting EIN) I change my LLC type   (disregarded entity or C type or S type or corporation or change in   number of members) for tax saving ? You marked your question as ""real-estate"", so I'm guessing you're holding rental properties in your LLC. That means that you will not be able to qualify for S-Corp, only C-Corp treatment. That in turn means that you'll be subject to double taxation and corporate tax rate. I fail to see what tax savings you're expecting in this situation. But yes, you can do it, if you so wish. I suggest you talk to a licensed tax adviser (EA/CPA licensed in your State) before you make any changes, because it will be nearly impossible to reverse the check-the-box election once made (for at least 5 years)." Your question mixes up different things.  Your LLC business type is determined by how you organize your business at the state level.  Separately, you can also elect to be treated in one of several different status for federal taxation. (Often this automatically changes your tax status at the state level too, but you need to check that with your state tax authority.) It is true that once you have an EIN, you can apply to be taxed as a C Corp or S Corp.  Whether or not that will result in tax savings will depend on the details of your business.  We won't be able to answer that for you.  You should get a professional advisor if you need help making that determination.
"I'm no lawyer and no expert, so take my remarks as entertainment only. Also see this question. If you have a U.S. SSN which is eligible for work, they may be able to pay you on 1099 basis with your SSN as a sole proprietor, unless they have some personal reason for avoiding that. So perhaps try asking about that specifically. HR policies can be weird and tricky, maybe a nudge in the right direction will help. Not What You Asked: regardless, I might recommend you register as an LLC and get an EIN (sort of SSN for companies) for a variety of reasons. It's called a ""limited liability"" company for a reason. You may also have an easier time reaping various business-related rewards, like writing off expenses. If you do so, consider a state with no income tax like Wyoming. (Or, for convenience sake, WA if you live in BC, or maybe NH if you live in Ontario.. etc.)" Ihre Zahungen sind bei uns sicher --Für jedes Unternehmen kommt irgendwann der Punkt, an dem ein Mahnverfahren notwendig wird.

The question seems to be from the point of view actual sales and not its impact on one's taxation. In case you just want to sell, why brokers will respond differently each times. Either there may be issues with ownership and/or the company whose shares it is? In case you feel that the issues lies with brok I called the IRS (click here for IRS contact info) and they said I do not need to get a new EIN.  I could have just filed the appropriate employer federal tax return (940/941) and then the filing requirements would have been updated.  But while I was on the phone, they just updated the filing requirements for my LLC so I am all good now (I still need to file the correct form and make the correct payments, etc. but I can use this same EIN going forward). Disclaimer: Don't trust me (or this answer) for tax advice (your situation may be different).  The IRS person on the phone was very helpful so I recommend calling them if you are in a similar situation.  FYI, I have found calling the IRS to always be very helpful. "Those are just a form of ""rent tax"" on real economy - that is, people that work in those non-productive sectors of economy are just using the fruits of labor of all the others.   But only the real economy actually matters - and having a few extra zeroes in the bank accounts of the rich don't really affect it as long as those money stay there.  Money that are not exchanged for real world goods and services don't really exist for the real economy." "Taxes are triggered when you sell the individual stock.      The IRS doesn't care which of your accounts the money is in.  They view all your bank and brokerage accounts as if they are one big account mashed together.   That kind of lumping is standard accounting practice for businesses. P/L, balance sheets, cash flow statements etc. will clump cash accounts as ""cash"".  Taxes are also triggered when they pay you a dividend.  That's why ETFs are preferable to mutual funds; ETFs automatically fold the dividends back into the ETF's value, so it doesn't cause a taxable event.  Less paperwork.  None of the above applies to retirement accounts.  They are special.  You don't report activity inside retirement accounts, because it would be very hard for regular folk to do that reporting, so that would discourage them from taking IRAs.   Taxes are paid at withdrawal time (or in Roth's, never.)" Having an EIN does not make the LLC a corporation -- your business can have an EIN even when treated like a sole proprietorship. An EIN is required to have a Individual 401(k), for example. But you can still be an LLC, taxed as a sole proprietor, and have a 401(k). You would need to file a Form 2553 with the IRS to elect S Corporation status. If you don't do that, you're still treated as a disregarded LLC. Whether or not you should make the election is another question. I've had zero taxable income for the past 2 years and yet the calculations say I owe the government $250 for each year for the Self Employment tax.  How can they charge a non-zero tax on my income when my taxable income is zero?  That is theft. That demands reform.
