How to properly report income without 1099-MISC
You are right that even if you do not receive a 1099-MISC, you still need to report all income to the IRS.  Report the $40 on Schedule C or Schedule C-EZ.  Since your net profit was less than $400, you do not need to file Schedule SE.  From the IRS web site: Self-Employment Income It is a common misconception that if a taxpayer does not receive a Form 1099-MISC or if the income is under $600 per payer, the income is not taxable. There is no minimum amount that a taxpayer may exclude from gross income. All income earned through the taxpayer’s business, as an independent contractor or from informal side jobs is self-employment income, which is fully taxable and must be reported on Form 1040. Use Form 1040, Schedule C, Profit or Loss from Business, or Form 1040, Schedule C-EZ, Net Profit from Business (Sole Proprietorship) to report income and expenses. Taxpayers will also need to prepare Form 1040 Schedule SE for self-employment taxes if the net profit exceeds $400 for a year. Do not report this income on Form 1040 Line 21 as Other Income. Independent contractors must report all income as taxable, even if it is less than $600. Even if the client does not issue a Form 1099-MISC, the income, whatever the amount, is still reportable by the taxpayer.
"Perhaps the real question you are asking is ""How can the tax code be fixed to make it simple for everyone (including me), and what would it take to effect those changes""? There are really two causes for the complexity of the tax code. Many of those who enter Government hold a desire for power, and Government uses the tax code as one lever of power to distribute largess to their supporters, and to nudge everyone to behaviors which they favor. The current system enables incumbents to spend taxpayer money to reward those they favor, and thus they accumulate power and security. Those who enter Government also love to spend money (especially other people's money), and their rapacious behavior recognizes no boundaries. They will spend money without control until the taxpayers yank them to a brutal stop. They enact complex rules which are used to ease the (tax) burden for some, which buys their support (with taxpayer money), and they spend money to benefit those which they favor. The system of lobbyists and contributors exists to entice Government to treat them and the causes they support favorably. This system enables incumbents to spend taxed money to reward those they favor, and to tax those they disfavor. Thus their greed is satisfied, and their power is increased. The freedom you seek is not available, although you can minimize the effort required for compliance. You can take the standard deduction, and use nothing but the W-2 provided by your employer, and unless you are subject to the Alternative Minimum Tax, you will find that the tax software will do most of the work for you. Do you want to approach the Nirvana of minimal effort to appease your tax collectors? Avoid starting your own business, charitable donations, investment income, 1099 income, and you will need minimal paperwork. Avoid earning enough to risk the AMT (Alternative Minimum Tax). Refuse to take the mortgage interest deduction, tax credits for electric vehicles, tax credits for high-efficiency appliances and air conditioners, tax credits for residential solar panel installations. Do not own investments which pay interest, or own stocks where you need to track the ""basis"" (purchase price) of the stocks, nor buy and then sell valuable items that might gain value (where you would need to track the purchase price, the ""basis""). Avoid owning and leasing a rental home for income, deducting businesses expenses and mileage for business purposes, contributions to a retirement plan (outside an employer plan) -- all complicate your tax filing. The solution you truly desire is either a ""Flat Tax"" or the ""Fair Tax"". These solutions would effect either a single tax rate (with no deductions or adjustments to income, yeah right), or a national retail sales tax, which would tax the money spent in the economy regardless of the source of the money (legal, gifts, crime) and there would be no need to report income, or classify it. The largest objection to either is that the tax code might become less ""progressive"" (increasing tax rate with increasing income). Good Luck!" "You can do either a 1099 or a W-2.  There is no limitations to the number of W-2s one can have in reporting taxes.  Problems occur, with the IRS, when one ""forgets"" to report income.  Even if one holds only one job at a time, people typically have more than one W-2 if they change jobs within the year. The W-2 is the simplest way to go and you may want to consider doing this if you do not intend to work this side business into significant income.   However, a 1099 gig is preferred by many in some situations.  For things like travel expenses, you will probably receive the income from these on a 1099, but you can deduct them from your income using a Schedule C.  Along these lines you may be able to deduct a wide variety of other things like travel to and from the client's location, equipment such as computers and office supplies, and maybe a portion of your home internet bill.  Also this opens up different retirement contributions schemes such as a simplified employee pension.   This does come with some drawbacks, however.  First your life is more complicated as things need to be documented to become actual business expenses.  You are much more likely to be audited by the IRS.  Your taxes become more complicated and it is probably necessary to employee a CPA to do them.  If you do this for primary full time work you will have to buy your own benefits.  Most telling you will have to pay both sides of social security taxes on most profits.  (Keep in mind that a good account can help you transfer profits to dividends which will allow you to be taxed at 15% and avoid social security taxes.) So it really comes down to what you see this side gig expanding into and your goals.  If you want to make this a real business, then go 1099, if you are just doing this for a fes months and a few thousand dollars, go W-2." "If she reported the income on the business return, I'd treat this as a ""mail audit"". Try to get a clear statement from Square confirming what they reported, under which SSN/EIN, for what transactions. Make a copy of that. If at all possible, get them to send a letter to the IRS (copy to you) acknowledging that they reported it under the wrong number. Copy the IRS's letter. Square's letter, and both personal and business 2012 returns. Write a (signed) cover letter explaining what had happened and pointing out the specific line in the business return which corresponded to the disputed amount, so they can see that you did report it properly and did pay taxes on it as business income. End that letter with a request for advice on how to straighten this out.  Certified-mail the whole package back to the IRS at whatever address the advisory letter gives. At worst, I'm guessing, they'll tell you to refile both returns for 2012 with that income moved over from the business return to the personal return, which will make everything match their records. But with all of this documentation in one place, they may be able to simply accept that Square misreported it and correct their files. Good luck. The IRS really isn't as unreasonable as people claim; if you can clearly document that you were trying to do the right thing, they try not to penalize folks unnecessarily." This sounds like a rental fee as described in the instructions for the 1099-MISC.   Enter amounts of $600 or more for all types of rents, such as    any of the following. ... Non-Employee compensation does not seem appropriate because you did not perform a service. You mention that your tax-preparer brought this up.  I think you will need to consult with a CPA to receive a more reliable opinion.  Make sure to bring the contract that describes the situation with you.  From there, you may need to consult a tax attorney, but the CPA should be able to help you figure out what your next step is. "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." "I think you're on the right track. Your #2 journal entry is incorrect. It should be (I usually put the debit entry on top, but I followed your formatting) I'm assuming your employer uses an accountable reimbursement plan (reimbursing you when you turn in your payment bill/receipts). This is not salary. Reimbursements under the accountable plan in the US are not taxed as income. If you think about it though, ""phone expense"" isn't really your phone expense. So, instead of #1 entry, you could make an account receivable, or other current asset account, maybe call it Reimbursables - cellphone, and debit this account, and credit your cash account. When you receive the $30 back, you will reverse the entries on the day of payment. If you do it this way, you should be able to see a list of receivables outstanding (I'm not too familiar with GNUCash but I'm sure it has this type of report)." One of the triggers for audit is when the IRS can't match 1099 income to the tax return. Whoever got the 1099 in her name should include that income on her return.
