Moving a personal business to a LLC accounting in California
You can move money in and out of the business at will, just keep track of every transaction. Ideally you'd use an accounting software like QuickBooks or similar. Create a Capital Contributions account and every time you put money into the business checking account record it as a Capital Contribution. Likewise, if you take money out of the business, it comes from your capital accounts. (You can create a separate Capital Distributions account in your accounting software, or just use a single account for contributions and distributions). Money coming in and out of those capital accounts is not taxable because you will pay taxes based on net earnings regardless of whether or not you have distributed any profits. So there's no need to make a loan to the company, which would have tax consequences. To reimburse yourself for purchases already made, submit an expense report to the company. If the company is unfunded right now, you can make a capital contribution to cover current expenses, submit the expense report, and wait until you have some profits before paying out the expense report or making any distributions.

"If the single active member lives in California and works at home, then you likely need to register in CA and pay the annual $800 franchise tax.  California is quite aggressive about enforcing registration of LLCs. A foreign LLC needs to register if it is ""doing business"" in California.  Here is a blog post that covers it in some detail.  It looks like you meet at least one of the criteria for doing business in California, such as:" As a new (very!) small business, the IRS has lots of advice and information for you. Start at https://www.irs.gov/businesses/small-businesses-self-employed and be sure you have several pots of coffee or other appropriate aid against somnolence.  By default a single-member LLC is 'disregarded' for tax purposes (at least for Federal, and generally states follow Federal although I don't know Mass. specifically), although it does have other effects. If you go this route you simply include the business income and expenses on Schedule C as part of your individual return on 1040, and the net SE income is included along with your other income (if any) in computing your tax. TurboTax or similar software should handle this for you, although you may need a premium version that costs a little more.  You can 'elect' to have the LLC taxed as a corporation by filing form 8832, see https://www.irs.gov/businesses/small-businesses-self-employed/limited-liability-company-llc . In principle you are supposed to do this when the entity is 'formed', but in practice AIUI if you do it by the end of the year they won't care at all, and if you do it after the end of the year but before or with your first affected return you qualify for automatic 'relief'. However, deciding how to divide the business income/profits into 'reasonable pay' to yourself versus 'dividends' is more complicated, and filling out corporation tax returns in addition to your individual return (which is still required) is more work, in addition to the work and cost of filing and reporting the LLC itself to your state of choice. Unless/until you make something like $50k-100k a year this probably isn't worth it. 1099 Reporting. Stripe qualifies as a 'payment network' and under a recent law payment networks must annually report to IRS (and copy to you) on form 1099-K if your account exceeds certain thresholds; see https://support.stripe.com/questions/will-i-receive-a-1099-k-and-what-do-i-do-with-it  . Note you are still legally required to report and pay tax on your SE income even if you aren't covered by 1099-K (or other) reporting. Self-employment tax. As a self-employed person (if the LLC is disregarded) you have to pay 'SE' tax that is effectively equivalent to the 'FICA' taxes that would be paid by your employer and you as an employee combined. This is 12.4% for Social Security unless/until your total earned income exceeds a cap (for 2017 $127,200, adjusted yearly for inflation), and 2.9% for Medicare with no limit (plus 'Additional Medicare' tax if you exceed a higher threshold and it isn't 'repealed and replaced'). If the LLC elects corporation status it has to pay you reasonable wages for your services, and withhold+pay FICA on those wages like any other employer. Estimated payments. You are required to pay most of your individual income tax, and SE tax if applicable, during the year (generally 90% of your tax or your tax minus $1,000 whichever is less). Most wage-earners don't notice this because it happens automatically through payroll withholding, but as self-employed you are responsible for making sufficient and timely estimated payments, and will owe a penalty if you don't. However, since this is your first year you may have a 'safe harbor'; if you also have income from an employer (reported on W-2, with withholding) and that withholding is sufficent to pay last year's tax, then you are exempt from the 'underpayment' penalty for this year.  If you elect corporation status then the corporation (which is really just you) must always make timely payments of withheld amounts, according to one of several different schedules that may apply depending on the amounts; I believe it also must make estimated payments for its own liability, if any, but I'm not familiar with that part. In addition to asking an accountant, I would also ask a lawyer.  When exploring the same question for myself, I found that one of the benefits of incorporating or forming an LLC is that your personal assets are better protected.   Including asset protection, here are 5 reasons to incorporate: Initially, I thought that as I had so few assets, I should not be concerned.  I was glad I was able to do a free consult with a lawyer who advised me to look into forming an LLC.  (Ultimately, my planned business idea never panned out.  So, I never went the incorporation/LLC route.)  Hope this helps! The cost will be around $300-$500 if you do it correctly it in Florida and can be over a $1,000 if you do it in New York (New York is more expensive due to a publication requirement that New York has for LLC’s).  The price ranges I’ve given include filing, state fees, getting a tax ID number (EIN), operating agreement, membership certificates, registered agent fees and publication fees if done in New York. Each state also have licensing boards and city fees that are applicable, so you would want to also make sure that you are keeping compliant there. Yearly paperwork to keep the LLC running won’t be so expensive, expect the state to charge a yearly fee and require some basic information to be submitted.  I had a quick look at Florida, and with someone filing it for you, expect around $200 to $250 a year, plus registered agent fees.  If you are late in Florida the penalty is $400 so you definitely would want a service that provides compliance calendar notifications to make sure you are on time with fees. In regards to bookkeeping and taxes, yearly tax filing will start at $250 to $500 for an LLC and move up from there depending on the services being offered and the amount of time of work.  I recently referred someone to an accountant that will charge $250 to file an almost zero tax return on an LLC.  I think $40 an hour is a little low for a bookkeeper but it all depends on where you are.  I know in some major cities bookkeepers expect $75 an hour or higher. So the expectation in Miami and Manhattan will probably be more expensive than Jacksonville and Albany. If you doing a little business don’t expect the cost to be too much on the bookkeeping. So, breakdown: $300-$500 (FL) - $1,000 (NY) Registration of LLC + any business license, city or other registrations $250 Yearly Fee + Yearly Registered Agent + any business licenses, city or other fee $500 Tax Return + Bookkeeping Fee Banks will charge more than a personal account so expect $120 a year plus. In regards to service I would look at companies that specialize in foreigners setting up  businesses in the US, because they will have services designed to help you more than services that primarily specialize with US clients. You are going to have some different needs, based on not having a Social Security Number or establishing from overseas.

You're evaluating an LLC vs a Corporation (both corporate entities).  Both have one or more members, and both are seen similarly (emphasis on SIMILAR here, they're not all the same) to the IRS.  Specifically, LLC's can opt for a pass-through tax system, basically seen by the IRS the same way an S-Corp is. Put another way, you can be taxed as a corporate entity, or it's P/L statements can ""flow through"" to your personal taxes.  When you opt for a flow-through, the business files and you get a separate schedule to tie into your taxes.  You should also look at filing a business expense schedule (Schedule C) on your taxes to claim legitimate business expenses (good reference point here). While there are several differences (see this, and this, and this) between these entities, the best determination on which structure is best for you is usually if you have full time employ while you're running the business.  S corps limit shares, shareholders and some deductions, but taxes are only paid by the shareholders.  C corps have employees, no restrictions on types or number of stock, and no restrictions on the number of shareholders.  However, this means you would become an employee of your business (you have to draw monies from somewhere) and would be subject to paying taxes on your income, both as an individual, and as a business (employment taxes such as Social Security, Medicare, etc). From the broad view of the IRS, in most cases an LLC and a Corp are the same type of entity (tax wise).  In fact, most of the differences between LLCs and Corps occur in how Profits/losses are distributed between members (LLCs are arbitrary to a point, and Corps base this on shares). Back to your question IMHO, you should opt for an LLC.  This allows you to work out a partnership with your co-worker, and allows you to disburse funds in a more flexible manner.  From Wikipedia : A limited liability company with multiple members that elects to be taxed as partnership may specially allocate the members' distributive share of income, gain, loss, deduction, or credit via the company operating agreement on a basis other than the ownership percentage of each member so long as the rules contained in Treasury Regulation (26 CFR) 1.704-1 are met. S corporations may not specially allocate profits, losses and other tax items under US tax law. Hope this helps, please do let me know if you have further questions.  As always, this is not legal or tax advice, just what I've learned in setting several LLCs and Corporate structures up over the years. EDIT: As far as your formulas go, the tax rate will be based upon your personal income, for any pass through entity.  This means that the same monies earned from and LLC or an S-corp, with the same expenses and the same pass-through options will be taxed the same. More reading: LLC and the law (Google Group)" "I expect the company wanted to pay you for a product (on a purchase order) rather than as  a contract laborer. Whatever. Would they be willing to re-issue the check to you as a sole proprietor of a business named ABC Consulting (or anything like that)? You can register your sole proprietor business with the state using a ""Doing Business As"" (DBA, or fictitious name), and then open the bank account for your business using the check provided by the customer as the first deposit. (There is likely a smaller registration fee for the DBA.) If they won't re-issue the check and you have to go the LLC route... Scrounge up $125 doing odd jobs or borrowing from a friend or parents. Seriously, anyone can earn that amount of money in a week or two. Besides the filing fee for the LLC, your bank may require you to provide an Operating Agreement (which is not required by the State). The Operating Agreement can be simple, or more complex if you have a partner (even if it's a spouse). If you do have a partner, it is essential to have such an agreement because it would specify the responsibilities and benefits allocated to each partner, particularly in the event of equity distributions (taking money out of the business, or liquidating and ending the LLC). There are websites that will provide you a boilerplate form for Operating Agreements. But if your business is anything more than just single member LLC, you should pay an attorney to draw one up for you so the wording is right. It's a safeguard against potential future lawsuits. And, while we're at it, don't forget to obtain a EIN (equivalent to a SSN) from the IRS for your LLC. There's no cost, but you'll have to have it to file taxes as a business for every year the LLC exists and has income. Good luck!" Thanks for your input.  &gt; Are you talking about domicile?  Nope, **domestication**. See #2 [here]. I've seen that term on a few places on the web.  I am a single-member LLC. I think I'll probably get a biz attorney. Do you think it matters whether the attorney is within the state I currently reside as opposed to the one I'm moving to?
