Calculate Estimated Tax on Hobby Business LLC
"You are on the right track, for tax purposes its all ordinary income at the end of 2016. If the free lance ""employer"" will withhold fed,state and local tax, then that takes care of your estimated tax. If they can't or won't, you will need to make those estimates and make payments quarterly for the fed and state tax at your projected tax liability.  Or, you can bump up withholding by your day job employer and cover your expected tax liability at year end without making estimated tax payments." "I assume your employer does standard withholding?  Then what you need to do is figure what bracket that puts you in after you've done all your normal deductions.  Let's say it's 25%.  Then multiply your freelance income after business expenses, and that's your estimated tax, approximately.  (Unless the income causes you to jump a bracket.) To that you have to add approximately 12-13% Social Security/Medicare for income between the $90K and $118,500.  Filling out Form 1040SSE will give you a better estimate. But there is a ""safe harbor"" provision, in that if what you pay in estimated tax (and withholding) this year is at least as much as you owed last year, there's no penalty.  I've always done mine this way, dividing last year's tax by 4, since my income is quite variable, and I've never been able to make sense of the worksheets on the 1040-ES."
There is a shortcut you can use when calculating federal estimated taxes.  Some states may allow the same type of estimation, but I know at least one (my own--Illinois) that does not. The shortcut: you can completely base your estimated taxes for this year on last year's tax return and avoid any underpayment penalty.  A quick summary can be found here (emphasis mine): If your prior year Adjusted Gross Income was $150,000 or less, then   you can avoid a penalty if you pay either 90 percent of this year's   income tax liability or 100 percent of your income tax liability from   last year (dividing what you paid last year into four quarterly   payments). This rule helps if you have a big spike in income one year,   say, because you sell an investment for a huge gain or win the   lottery. If wage withholding for the year equals the amount of tax you   owed in the previous year, then you wouldn't need to pay estimated   taxes, no matter how much extra tax you owe on your windfall. Note that this does not mean you will not owe money when you file your return next April; this shortcut ensures that you pay at least the minimum allowed to avoid penalty. You can see this for yourself by filling out the worksheet on form 1040ES.  Line 14a is what your expected tax this year will be, based on your estimated income.  Line 14b is your total tax from last year, possibly with some other modifications.  Line 14c then asks you to take the lesser of the two numbers.  So even if your expected tax this year is one million dollars, you can still base your estimated payments on last year's tax. IRS has it spelled out Business or Hobby? This is wrong.  It should be  or  Now, to get back to self-employment tax.  Self-employment tax is weird.  It's a business tax.  From the IRS perspective, any self-employed person is a business.  So, take your income X and divide by 1.0765 (6.2% Social Security and 1.45% Medicare).  This gives your personal income.  Now, to calculate the tax that you have to pay, multiply that by .153 (since you have to pay both the worker and employer shares of the tax).   So new calculation  or they actually let you do  which is better for you (smaller).   And your other calculations change apace.   And like I said, you can simplify Q1se to  and your payment would be  Now, to get to the second quarter.  Like I said, I'd calculate the income through the second quarter.  So recalculate A based on your new numbers and use that to calculate Q2i.   or  Note that this includes income from both the first and second quarters.  We'll reduce to just the second quarter later.  This also has you paying for all of June even though you may not have been paid when you make the withholding payment.  That's what they want you to do.   But we aren't done yet.  Your actual payment should be  or  Because Q2ft and Q2se are what you owe for the year so far.  Q1ft + Q1se is what you've already paid.  So you subtract those from what you need to pay in the second quarter.  In future quarters, this would be  All that said, don't stress about it.  As a practical matter, so long as you don't owe $1000 or more when you file your actual tax return, they aren't going to care.  So just make sure that your total payments match by the payment you make January 15th.   I'm not going to try to calculate for the state.  For one thing, I don't know if your state uses Q1i or Q1pi as its base.  Different states may have different rules on that.  If you can't figure it out, just use Q1i, as that's the bigger one.  Fix it when you file your annual return.  The difference in withholding is going to be relatively small anyway, less than 1% of your income. Don't overthink it. As an employee, whether of your own corporation or of someone else, you get a salary and there are deductions taken out. As the owner of a business you get (hopefully) business profits as well. And, in general, you often have other sources of income from investments, etc. Your estimated tax payments are based on the difference between what was withheld from your salary and what you will owe, based on salary, business income, and other sources. So, in essence, you just add up all the income you expect, estimate what the tax bill will be, and subtract what's been withheld. That's your estimated tax payment. "These kinds of questions can be rather tricky. I've struggled with this sort of thing in the past when I had income from a hobby, and I wanted to ensure that it was indeed ""hobby income"" and I didn't need to call it ""self-employment"". Here are a few resources from the IRS: There's a lot of overlap among these resources, of course. Here's the relevant portion of Publication 535, which I think is reasonable guidance on how the IRS looks at things: In determining whether you are carrying on an activity for profit, several factors are taken into account. No one factor alone is decisive. Among the factors to consider are whether: Most of the guidance looks to be centered around what one would need to do to convince the IRS that an activity actually is a business, because then one can deduct the ""business expenses"", even if that brings the total ""business income"" negative (and I'm guessing that's a fraud problem the IRS needs to deal with more often). There's not nearly as much about how to convince the IRS that an activity isn't a business and thus can be thrown into ""Other Income"" instead of needing to pay self-employment tax. Presumably the same principles should apply going either way, though. If after reading through the information they provide, you decide in good faith that your activity is really just ""Other income"" and not ""a business you're in on the side"", I would find it likely that the IRS would agree with you if they ever questioned you on it and you provided your reasoning, assuming your reasoning is reasonable. (Though it's always possible that reasonable people could end up disagreeing on some things even given the same set of facts.) Just keep good records about what you did and why, and don't get too panicked about it once you've done your due diligence. Just file based on all the information you know." "-Alain Wertheimer I'm a hobbyist... Most (probably all) of those older items were sold both prior to my establishing the LLC This is a hobby of yours, this is not your business. You purchased all of these goods for your pleasure, not for their future profit. The later items that you bought after your LLC was establish served both purposes (perks of doing what you love).  How should I go about reporting this income for the items I don't have records for how much I purchased them for?  There's nothing you can do. As noted above, these items (if you were to testify in court against the IRS). ""Losses from the sale of personal-use property, such as your home or car, aren't tax deductible."" Source Do I need to indicate 100% of the income because I can't prove that I sold it at a loss? Yes, if you do not have previous records you must claim a 100% capital gain. Source Addition: As JoeTaxpayer has mentioned in the comments, the second source I posted is for stocks and bonds.  So at year begin of 2016, I started selling what I didn't need on eBay and on various forums [January - September]. Because you are not in the business of doing this, you do not need to explain the cost; but you do need to report the income as Gross Income on your 1040. Yes, if you bought a TV three years ago for a $100 and sold it for $50, the IRS would recognize you earning $50.  As these are all personal items, they can not be deducted; regardless of gain or loss. Source Later in the year 2016 (October), I started an LLC (October - December) If these are items that you did not record early in the process of your LLC, then it is reported as a 100% gain as you can not prove any business expenses or costs to acquire associated with it.  Source Refer to above answer.  Refer to above answer.  Conclusion Again, this is a income tax question that is split between business and personal use items. This is not a question of other's assessment of the value of the asset. It is solely based on the instruments of the IRS and their assessment of gains and losses from businesses. As OP does not have the necessary documents to prove otherwise, a cost basis of $0 must be assumed; thus you have a 100% gain on sale." It's income. It's almost certainly subject to income tax. As miscellaneous income, if nothing else. (That's what hobby income usually falls under.) If you kept careful records of the cost of developing the app, you might be able to offset those against the income... again, as with hobby income. "From the poster's description of this activity, it doesn't look like he is engaged in a business, so Schedule C would not be appropriate. The first paragraph of the IRS Instructions for Schedule C is as follows: Use Schedule C (Form 1040) to report income or loss from a business   you operated or a profession you practiced as a sole proprietor. An   activity qualifies as a business if your primary purpose for engaging   in the activity is for income or profit and you are involved in the   activity with continuity and regularity. For example, a sporadic   activity or a hobby does not qualify as a business. To report income   from a nonbusiness activity, see the instructions for Form 1040, line   21, or Form 1040NR, line 21. What the poster is doing is acting as a nominee or agent for his members. For instance, if I give you $3.00 and ask you to go into Starbucks and buy me a pumpkin-spice latte, you do not have income or receipts of $3.00, and you are not engaged in a business. The amounts that the poster's members are forwarding him are like this.  Money that the poster receives for his trouble should be reported as nonbusiness income on Line 21 of Form 1040, in accordance with the instructions quoted above and the instructions for Form 1040. Finally, it should be noted that the poster cannot take deductions or losses relating to this activity. So he can't deduct any expenses of organizing the group buy on his tax return. Of course, this would not be the case if the group buy really is the poster's business and not just a ""hobby."" Of course, it goes without saying that the poster should document all of this activity with receipts, contemporaneous emails (and if available, contracts) - as well as anything else that could possibly be relevant to proving the nature of this activity in the event of an audit." "You report it when the expense was incurred/accrued. Which is, in your case, 2014. There's no such thing as ""accounts payable"" on tax forms, it is an account on balance sheet, but most likely it is irrelevant for you since your LLC is probably cash-based. The reimbursement is a red-herring, what matters is when you paid the money." "Re the business license - in California business licenses are given by the municipal/county governments, so you'll have to check that with your city hall or county office. Re taxes - yes, you'll have to pay taxes, as with any income. Services are considered ""imputed income"", and generally you'd recognize income to the extent they would be paying had they been paying the full price (or the actual cost of services provided, if more). Since this is a hobby and not a for-profit enterprise, your deductions may be limited by the actual income and the 2% AGI threshold. See more here." "It's not possible to determine whether you can ""expect a refund"" or whether you are claiming the right number of exemptions from the information given.   If your wife were not working and you did not do independent contracting, then the answer would be much simpler.  However, in this case, we must also factor in how much your contracting brings in (since you must pay income tax on that, as well as Medicare and, probably, Social Security), whether you are filing jointly or separately, and your wife's income from her business.   There are also other factors such as whether you'll be claiming certain child care expenses, and certain tax credits which may phase out depending on your income.   If you can accurately estimate your total household income for the year, and separate that into income from wages, contracting, and your wife's business, as well as your expenses for things like state and local income and property taxes, then you can make a very reasonable estimate about your total tax burden (including the self-employment taxes on your non-wage income) and then determine whether you are having enough tax withheld from your paycheck.  Some people may find that they should have additional tax withheld to compensate for these expenses (see IRS W-4 Line #6)." This new roof should go on the 2016 LLC business return, but you probably won't be able to expense the entire roof as a repair.  A new roof is most likely a capital improvement, which means that it would need to be depreciated over many years instead of expensed all in 2016.  The depreciation period for a residential rental property is 27.5 years.  Please consider seeking a CPA or Enrolled Agent for the preparation of your LLC business return. See also: IRS Tangible Property Regulations FAQ list When you made the loan to the LLC (by paying the contractor and making a contract with the LLC), did you state an interest rate?  If not, you and your brother should correct the contract so that an interest rate is stated, then follow it.  The LLC needs to pay you interest until the loan is paid off.  You need to report the interest income on your personal return, and the LLC needs to report the interest expense in its business return. "I have done similar software work. You do not need an LLC to write off business expenses. The income and expenses go on Schedule C of your tax return. It is easy to write off even small expenses such as travel - if you keep records. The income should be reported to you on a 1099 form, filled out by your client, not yourself.  For a financial advisor you should find one you can visit with personally and who operates as a ""fee-only"" advisor. That means they will not try to sell you something that they get a commission on. You might pay a few $hundred per visit. There are taxes that you have to pay (around 15%) due to self-employment income. These taxes are due 4 times a year and paid with an ""estimated tax"" form. See the IRS web site, and in particular schedule SE. Get yourself educated about this fast and make the estimated tax payments on time so you won't run into penalties at the end of the year." You can and are supposed to report self-employment income on Schedule C (or C-EZ if eligible, which a programmer likely is) even when the payer isn't required to give you 1099-MISC (or 1099-K for a payment network now). From there, after deducting permitted expenses, it flows to 1040 (for income tax) and Schedule SE (for self-employment tax). See https://www.irs.gov/individuals/self-employed for some basics and lots of useful links. If this income is large enough your tax on it will be more than $1000, you may need to make quarterly estimated payments (OR if you also have a 'day job' have that employer increase your withholding) to avoid an underpayment penalty. But if this is the first year you have significant self-employment income (or other taxable but unwithheld income like realized capital gains) and your economic/tax situation is otherwise unchanged -- i.e. you have the same (or more) payroll income with the same (or more) withholding -- then there is a 'safe harbor': if your withholding plus estimated payments this year is too low to pay this year's tax but it is enough to pay last year's tax you escape the penalty. (You still need to pay the tax due, of course, so keep the funds available for that.) At the end of the first year when you prepare your return you will see how the numbers work out and can more easily do a good estimate for the following year(s). A single-member LLC or 'S' corp is usually disregarded for tax purposes, although you can elect otherwise, while a (traditional) 'C' corp is more complicated and AIUI out-of-scope for this Stack; see https://www.irs.gov/businesses/small-businesses-self-employed/business-structures for more. From my 15 years of experience, no technical indicator actually ever works. Those teaching technical indicators are either mostly brokers or broker promoted so called technical analysts. And what you really lose in disciplined trading over longer period is the taxes and brokerages. That is why you will see that teachers involved in this field are mostly technical analysts because they can never make money in real markets and believe that they did not adhere to rules or it was an exception case and they are not ready to accept facts. The graph given above for coin flip is really very interesting and proves that every trade you enter has 50% probability of win and lose. Now when you remove the brokerage and taxes from win side of your game, you will always lose. That is why the Warren Buffets of the world are never technical analysts. In fact, they buy when all technical analysts fails. Holding a stock may give pain over longer period but still that is only way to really earn. Diversification is a good friend of all bulls. Another friend of bull is the fact that you can lose 100% but gain any much as 1000%. So if one can work in his limits and keep investing, he can surely make money. So, if you have to invest 100 grand in 10 stocks, but 10 grand in each and then one of the stocks will multiply 10 times in long term to take out cost and others will give profit too... 1-2 stocks will fail totally, 2-3 will remain there where they were, 2-3 will double and 2-3 will multiply 3-4 times. Investor can get approx 15% CAGR earning from stock markets... Cheers !!!
