How do I pay my estimated income tax?
Congratulations on starting your own business. Invest in a tax software package right away; I can't recommend a specific one but there is enough information out there to point you in the right direction: share with us which one you ended up using and why (maybe a separate question?) You do need to make your FICA taxes but you can write off the SE part of it. Keep all your filings as a PDF, a printout and a softcopy in the native format of the tax software package: it really helps the next tax season. When you begin your business, most of the expenses are going to be straightforward (it was for me) and while I had the option of doing it by hand, I used software to do it myself. At the beginning, it might actually seem harder to use the tax software package, but it will pay off in the end. Build relationships with a few tax advisors and attorneys: you will need to buy liability insurance soon if you are in any kind of serious (non hobby) business and accounting for these are no trivial tasks. If you have not filed yet, I recommend you do this: File an extension, overpay your estimated taxes (you can always collect a refund later) and file your return once you have had a CPA look over it. Do not skimp on a CPA: it's just the cost of running your business and you don't want to waste your time reading the IRS manuals when you could be growing your own business. Best of luck and come back to tell us what you did!
"I've done various side work over the years -- computer consulting, writing, and I briefly had a video game company -- so I've gone through most of this. Disclaimer: I have never been audited, which may mean that everything I put on my tax forms looked plausible to the IRS and so is probably at least generally right, but it also means that the IRS has never put their stamp of approval on my tax forms. So that said ... 1: You do not need to form an LLC to be able to claim business expenses. Whether you have any expenses or not, you will have to complete a schedule C. On this form are places for expenses in various categories. Note that the categories are the most common type of expenses, there's an ""other"" space if you have something different. If you have any property that is used both for the business and also for personal use, you must calculate a business use percentage. For example if you bought a new printer and 60% of the time you use it for the business and 40% of the time you use it for personal stuff, then 60% of the cost is tax deductible. In general the IRS expects you to calculate the percentage based on amount of time used for business versus personal, though you are allowed to use other allocation formulas. Like for a printer I think you'd get away with number of pages printed for each. But if the business use is not 100%, you must keep records to justify the percentage. You can't just say, ""Oh, I think business use must have been about 3/4 of the time."" You have to have a log where you write down every time you use it and whether it was business or personal. Also, the IRS is very suspicious of business use of cars and computers, because these are things that are readily used for personal purposes. If you own a copper mine and you buy a mine-boring machine, odds are you aren't going to take that home to dig shafts in your backyard. But a computer can easily be used to play video games or send emails to friends and relatives and lots of things that have nothing to do with a business. So if you're going to claim a computer or a car, be prepared to justify it. You can claim office use of your home if you have one or more rooms or designated parts of a room that are used ""regularly and exclusively"" for business purposes. That is, if you turn the family room into an office, you can claim home office expenses. But if, like me, you sit on the couch to work but at other times you sit on the couch to watch TV, then the space is not used ""exclusively"" for business purposes. Also, the IRS is very suspicious of home office deductions. I've never tried to claim it. It's legal, just make sure you have all your ducks in a row if you claim it. Skip 2 for the moment. 3: Yes, you must pay taxes on your business income. If you have not created an LLC or a corporation, then your business income is added to your wage income to calculate your taxes. That is, if you made, say, $50,000 salary working for somebody else and $10,000 on your side business, then your total income is $60,000 and that's what you pay taxes on. The total amount you pay in income taxes will be the same regardless of whether 90% came from salary and 10% from the side business or the other way around. The rates are the same, it's just one total number. If the withholding on your regular paycheck is not enough to cover the total taxes that you will have to pay, then you are required by law to pay estimated taxes quarterly to make up the difference. If you don't, you will be required to pay penalties, so you don't want to skip on this. Basically you are supposed to be withholding from yourself and sending this in to the government. It's POSSIBLE that this won't be an issue. If you're used to getting a big refund, and the refund is more than what the tax on your side business will come to, then you might end up still getting a refund, just a smaller one. But you don't want to guess about this. Get the tax forms and figure out the numbers. I think -- and please don't rely on this, check on it -- that the law says that you don't pay a penalty if the total tax that was withheld from your paycheck plus the amount you paid in estimated payments is more than the tax you owed last year. So like lets say that this year -- just to make up some numbers -- your employer withheld $4,000 from your paychecks. At the end of the year you did your taxes and they came to $3,000, so you got a $1,000 refund. This year your employer again withholds $4,000 and you paid $0 in estimated payments. Your total tax on your salary plus your side business comes to $4,500. You owe $500, but you won't have to pay a penalty, because the $4,000 withheld is more than the $3,000 that you owed last year. But if next year you again don't make estimated payment, so you again have $4,000 withheld plus $0 estimated and then you owe $5,000 in taxes, you will have to pay a penalty, because your withholding was less than what you owed last year. To you had paid $500 in estimated payments, you'd be okay. You'd still owe $500, but you wouldn't owe a penalty, because your total payments were more than the previous year's liability. Clear as mud? Don't forget that you probably will also owe state income tax. If you have a local income tax, you'll owe that too. Scott-McP mentioned self-employment tax. You'll owe that, too. Note that self-employment tax is different from income tax. Self employment tax is just social security tax on self-employed people. You're probably used to seeing the 7-whatever-percent it is these days withheld from your paycheck. That's really only half your social security tax, the other half is not shown on your pay stub because it is not subtracted from your salary. If you're self-employed, you have to pay both halves, or about 15%. You file a form SE with your income taxes to declare it. 4: If you pay your quarterly estimated taxes, well the point of ""estimated"" taxes is that it's supposed to be close to the amount that you will actually owe next April 15. So if you get it at least close, then you shouldn't owe a lot of money in April. (I usually try to arrange my taxes so that I get a modest refund -- don't loan the government a lot of money, but don't owe anything April 15 either.) Once you take care of any business expenses and taxes, what you do with the rest of the money is up to you, right? Though if you're unsure of how to spend it, let me know and I'll send you the address of my kids' colleges and you can donate it to their tuition fund. I think this would be a very worthy and productive use of your money. :-) Back to #2. I just recently acquired a financial advisor. I can't say what a good process for finding one is. This guy is someone who goes to my church and who hijacked me after Bible study one day to make his sales pitch. But I did talk to him about his fees, and what he told me was this: If I have enough money in an investment account, then he gets a commission from the investment company for bringing the business to them, and that's the total compensation he gets from me. That commission comes out of the management fees they charge, and those management fees are in the same ballpark as the fees I was paying for private investment accounts, so basically he is not costing me anything. He's getting his money from the kickbacks. He said that if I had not had enough accumulated assets, he would have had to charge me an hourly fee. I didn't ask how much that was. Whew, hadn't meant to write such a long answer!" Your capital gain is about $40K, which (assuming your total income is under $250K) is taxed at 15% long term capital gains rate. Additional depreciation recapture of approximately $5K is taxed at 25%. So this gives us rough estimate of $7250 tax. This is Federal tax, AZ rates are somewhere between 2% and 4%, so you'll be looking at some $1.6K additional tax to AZ. If you have accumulated rental losses or other expenses, it will lower the total amount of your gain (and, accordingly, the taxes). This is all very rough estimates, and you shouldn't rely on this but verify on your own or with a professional. I suggest using professional services because while being costly, they will probably save you more in taxes than you'll have to pay them because of the knowledge of what exactly of your expenses can be deducted and how to calculate the cost basis correctly. (edit from JoeT - the home exclusion requires occupancy for 2 of prior 5 years. For the OP, the prorated $125k exclusion 'might' cover the gain, it depends when the increase in value occurred, if the gain was during the time rented, it's taxable, I believe.) The are a couple of explanations that I can think of; though for determining exactly what is different you will want to print out both returns and compare them line by line to see how they differ. If the company grossed up your income to account for the taxes on housing (possibly by paying the additional withholding), you may be just benefiting from them estimating your tax rate. This can especially be the case if your only work was the three month internship. They would have to assume your salary was for the entire year. There is an earned income tax credit for low wage earners that you may have qualified for (it would depend your specific circumstances if you meet the criteria). But that credit for a range of income actually pays out more the more you earn (to encourage working that extra hour instead of reducing benefit because you had another hour of employment). As for the housing subsidy itself, while the value is quite high the IRS considers that to be a taxable benefit that the employer provided you and so it needs to be added to your W-2 wages. $8k a month seems quite high, but I don't know the quality of the apartment you were provided and what the going rates are in the area. Given that you said you worked for a major tech company, I can imagine that you might have been working in an area with high rents. If the employer did gross up your paycheck so as to cover your taxes, that $24k would also include that extra tax payment (e.g. if the employer paid $8k in additional taxes for you, then the housing cost that they directly paid were $16k). "Trying to figure out how much money you have available each day sounds like you're making this more complicated than it needs to be. Unless you're extremely tight and you're trying to squeeze by day by day, asking ""do I have enough cash to buy food for today?"" and so on, you're doing too much work. Here's what I do. I make a list of all my bills. Some are a fixed amount every month, like the mortgage and insurance premiums. Others are variable, like electric and heating bills, but still pretty predictable.  Most bills are monthly, but I have a few that come less frequently, like water bills in my area come every 3 months and I have to pay property taxes twice a year. For these you have to calculate how much they cost each month. Like for the water bill, it's once every 3 months so I divide a typical bill by 3. Always round up or estimate a little high to be safe. Groceries are a little tricky because I don't buy groceries on any regular schedule, and sometimes I buy a whole bunch at once and other times just a few things. When groceries were a bigger share of my income, I kept track of what I spent for a couple of months to figure out an average per month. (Today I'm a little richer and I just think of groceries as coming from my spending money.) I allocate a percentage of my income for contributions to church and charities and count this just like bills. It's a good idea to put aside something for savings and/or paying down any outstanding loans every month. Then I add these up to say okay, here's how much I need each month to pay the bills. Subtract that from my monthly income and that's what I have for spending money. I get paid twice a month so I generally pay bills when I get paid. For most bills the due date is far enough ahead that I can wait the maximum half a month to pay it. (Worst case the bill comes the day after I pay the bills from this paycheck.)  Then I keep enough money in my checking account to, (a) Cover any bills until the next paycheck and allow for the particularly large bills; and (b) provide some cushion in case I make a mistake -- forget to record a check or make an arithmetic error or whatever; and (c) provide some cushion for short-term unexpected expenses. To be safe, (a) should be the total of your bills for a month, or as close to that as you can manage. (b) should be a couple of hundred dollars if you can manage it, more if you make a lot of mistakes. If you've calculated your expenses properly and only spend the difference, keeping enough money in the bank should fall out naturally. I think it's a lot easier to try to manage your money on a monthly basis than on a daily basis. Most of us don't spend money every day, and we spend wildly different amounts from day to day. Most days I probably spend zero, but then one day I'll buy a new TV or computer and spend hundreds.  Update in response to question What I do in real life is this: To calculate my available cash to spend, I simply take the balance in my checking account -- assuming that all checks and electronic payments have cleared. My mortgage is deducted from my checking every month so I post that to my checking a month in advance. I pay a lot of things with automatic charges to a credit card these days, so my credit card bills are large and can't be ignored. So subtract my credit card balances. Subtract my reserve amount. What's left is how much I can afford to spend. So for example: Say I look at the balance in my checkbook today and it's, say, $3000. That's the balance after any checks and other transactions have cleared, and after subtracting my next mortgage payment. Then I subtract what I owe on credit cards. Let's say that was $1,200. So that leaves $1,800. I try to keep a reserve of $1,500. That's plenty to pay my routine monthly bills and leave a healthy reserve. So subtract another $1,500 leaves $300. That's how much I can spend. I could keep track of this with a spreadsheet or a database but what would that gain? The amount in my checking account is actual money. Any spreadsheet could accumulate errors and get farther and farther from accurate values. I use a spreadsheet to figure out how much spending money I should have each month, but that's just to use as a guideline. If it came to, say, $100, I wouldn't make grandiose plans about buying a new Mercedes. If it came to $5,000 a month than buying a fancy new car might be realistic. It also tells me how much I can spend without having to carefully check balances and add it up. These days I have a fair amount of spending money so when, for example, I recently decided I wanted to buy some software that cost $100 I just bought it with barely a second thought. When my spending money was more like $100 a month, lunch at a fast food place was a big event that I planned weeks in advance. (Obviously, I hope, don't get stupid about ""small amounts"". If you can easily afford $100 for an impulse purchase, that doesn't mean that you can afford $100 five times a day every day.) Two caveats: 1. It helps to have a limited number of credit cards so you can keep the balances under control. I have two credit cards I use for almost everything, so I only have two balances to keep track of. I used to have more and it got confusing, it was easy to lose track of how much I really owed, which is a set up for getting in trouble." The committee folks told us Did they also give you advice on your medication? Maybe if they told you to take this medicine or that you'd do that? What is it with people taking tax advice from random people? The committee told you that one person should take income belonging to others because they don't know how to explain to you which form to fill. Essentially, they told you to commit a fraud because forms are hard. I now think about the tax implications, that makes me pretty nervous. Rightly so. Am I going to have to pay tax on $3000 of income, even though my actual winning is only $1000? From the IRS standpoint - yes. Can I take in the $3000 as income with $2000 out as expenses to independent contractors somehow? That's the only solution. You'll have to get their W8's, and issue 1099 to each of them for the amounts you're going to pay them. Essentially you volunteered to do what the award committee was supposed to be doing, on your own dime. Note that if you already got the $3K but haven't paid them yet - you'll pay taxes on $3K for the year 2015, but the expense will be for the year 2016. Except guess what: it may land your international students friends in trouble. They're allowed to win prizes. But they're not allowed to work. Being independent contractor is considered work. While I'm sure if USCIS comes knocking, you'll be kind enough to testify on their behalf, the problem might be that the USCIS won't come knocking. They'll just look at their tax returns and deny their visas/extensions. Bottom line, next time ask a professional (EA/CPA licensed in your State) before taking advice from random people who just want the headache of figuring out new forms to go away. They are four quarterly estimated tax payments.   The IRS requires that you pay your taxes throughout the year (withholding in a W-2 job).  You'll need to estimate how much taxes you think you might be owing and then pay roughly 1/4 at each of the 4 deadlines. From the IRS: How To Figure Estimated Tax To figure your estimated tax, you must   figure your expected AGI, taxable   income, taxes, deductions, and credits   for the year. When figuring your 2011 estimated tax,   it may be helpful to use your income,   deductions, and credits for 2010 as a   starting point. Use your 2010 federal   tax return as a guide. You can use   Form 1040-ES to figure your estimated   tax. Nonresident aliens use Form   1040-ES (NR) to figure estimated tax. You must make adjustments both for   changes in your own situation and for   recent changes in the tax law. For   2011, there are several changes in the   law. Some of these changes are   discussed under What's New for 2011   beginning on page 2. For information   about these and other changes in the   law, visit the IRS website at IRS.gov. The instructions for Form 1040-ES   include a worksheet to help you figure   your estimated tax. Keep the worksheet   for your records. You may find some value from hiring a CPA to help you setup your estimated tax payments and amounts. "You can simply use the previous year's tax liability as your basis for payments. Take the amount of tax you owed the previous year, divide by four, and use that amount for your estimated payments. As long as you're paying 100% of what you owed last year, you won't have any penalty. Except if your AGI is above a certain limit ($150k for married filing jointly in 2011), then you have to pay 110%. See IRS Pub 505 for details (general rule, special rule, under ""Higher Income Taxpayers""). (H/T to @Dilip Sarwate for pointing out the 110% exception in a comment below.)" "If you're making $80k, and you're consulting for an extra $400/wk or $20,800/yr, you're earning a total of $100,800.  That's assuming you do it for a full calendar year of course.  Either way, assuming you can deduct/exclude at least $11k of income (as almost everyone can), you're paying 25% on your marginal dollars.  (This also assumes you're single; if you're married/filing jointly, this may not be true.)  Note, you're right at the edge of the 25% bracket if you earn this in a full calendar year - but if you have a 401k, health insurance, or other reductions you'll be fine.  Additionally, for this year you'll be under (again assuming single and no other income) because you aren't earning a full year's worth. Assuming your $80k is precisely taken care of by your regular withholding, then, you will literally pay 25%*$400/week in additional taxes - $100 per week.  So if you are paid biweekly, you need to add $200/week in withholding on your W-4.  If you expect to overpay taxes (if you own a house with a mortgage for example, you often do), you can reduce it some, but adding $200/biweekly paycheck should bring you right to where you were before the extra income. The general rule is to calculate your marginal (not effective) tax rate before the new income, assuming default withholding takes care of that, and then withhold the marginal rate for the new income [checking that the new income doesn't push the marginal rate up - if so, calculate in two parts, the part in the lower marginal rate and the part in the higher marginal rate]. You can google ""2014 tax brackets"", or look at the IRS tax tables for detailed information about marginal rates."
