IRS Audit & Refund Notice Assistance for Day Traders in Chicago

The IRS does not hand out trader tax status, you have to earn it with the facts of how you trade, and in an audit the burden is on you to show it. There is no single test in the code, so the IRS and the courts look at a pattern. They want to see that you trade often, on most market days rather than a few times a month, that your holding periods are short and measured in hours or days rather than months, that you are trying to profit from short swings in price rather than from dividends and long term appreciation, and that the activity is continuous and looks like a business you run rather than an investment you tend. A day trader who placed a few hundred trades over the year, held for weeks, and mostly collected dividends is going to have a hard time, no matter what they wrote on the return.

The way you win that argument is with records, gathered before the audit rather than after. A complete trade log that shows the date, the instrument, the entry and exit, and the holding period is the backbone of the defense, because it proves the frequency and the short holding periods in one document. A calendar of trading days shows the regularity. Notes on your method, your hours at the screen, and your setup show that this is how you make your living and not a hobby. We build that record with you through the year, so when the IRS asks how many days you traded and how long you held, the answer is a spreadsheet and not a shrug.

The stakes are real, because trader status controls two things. First, it lets you deduct the cost of trading as a business on a Schedule C, the platform fees, the data feeds, the home office used only for trading, and the education, none of which an ordinary investor can write off since the 2018 suspension of those deductions. Second, only a qualifying trader can make the mark to market election under Section 475(f). If the IRS reclassifies you from trader to investor, both of those disappear. Say you deducted 15,000 dollars of trading business expenses on your Schedule C. A reclassification to investor disallows that 15,000 dollars, raising your federal taxable income, and because Illinois starts from your federal number, it raises your Illinois tax at the flat 4.95 percent too, about 743 dollars more to the state on top of the federal bill.

That is why the defense is really about the record, and the record is built long before a notice arrives. We document your trading pattern honestly, tell you where you genuinely stand on trader status rather than where you wish you stood, and assemble the trade log, the day count, and the expense support into a package that answers an examiner point by point. When an audit is already open, we represent you and respond to the information requests on time, and when it is not, we set your records up so a future challenge is a short conversation. That work runs through our tax compliance service, the trader tests come from the IRS guidance on traders in securities, the examination process from the IRS material on audits, and the state rate a reclassification raises from the Illinois Department of Revenue.

A CP2000 is not an audit, though it lands with the same jolt, and for a day trader it is one of the most common notices there is. It is generated automatically when the income the IRS has on file from third parties does not match what your return reported. Your broker sends the IRS a Form 1099-B for every account, showing proceeds and, in most cases, cost basis. If the totals on your return do not line up with those 1099-B figures, the computer flags it and proposes additional tax, plus interest and sometimes a penalty. Because a day trader can generate thousands of transactions in a year, there is a lot of room for the numbers to diverge, and the notice can propose a frightening balance built on a matching error rather than a real underpayment.

The wash sale rule is the usual culprit. Under Section 1091, when you sell at a loss and rebuy the same security within 30 days, the loss is deferred, and an active trader triggers this constantly. Your broker reports wash sales on the 1099-B a particular way, and if your return handled them differently, the totals will not match and the CP2000 will read the difference as unreported gain. Say the notice proposes tax on 110,000 dollars of additional gain that is really trapped wash sale losses, not new income. Left unanswered, the IRS will assess tax on that 110,000 dollars, and Illinois will follow with its own 4.95 percent, about 5,445 dollars of state tax on a phantom number. The fix is a reconciliation that shows the IRS how your reported figures tie to the 1099-B, not a check for tax you do not owe.

Section 1256 futures are the other frequent trigger. Futures and broad based index options are marked to market and taxed 60 percent long term and 40 percent short term on Form 6781, a completely different path from the Schedule D and Form 8949 route for stocks. A CP2000 can appear when those 1256 gains were reported one way by the broker and another way on your return, or when they were dropped onto the wrong form. Answering it means showing the correct 60/40 treatment and where it belongs, which often reduces the proposed tax rather than confirming it, because the automated notice does not know your futures got the favorable split.

The worst thing you can do with a CP2000 is ignore it, because the proposed changes become an assessment if you do not respond by the deadline, usually 30 days. The second worst thing is to simply pay it, because a large share of these notices are matching errors that a clean reconciliation makes disappear. We read the notice, pull your broker records, rebuild the reconciliation between your return and the 1099-B, and write the response that either corrects the IRS or agrees only to the part that is genuinely owed. We handle the Illinois side in the same motion, since a federal change flows to the state return. That work runs through our tax compliance service, the notice itself is explained in the IRS CP2000 guidance, the wash sale mechanics in IRS Publication 550, and the state rate that follows a federal change comes from the Illinois Department of Revenue.

Yes, and the refund window is the clock that matters for a day trader. Someone who overpaid because a prior return mishandled wash sales, dropped the 60/40 treatment on 1256 futures, or missed a deduction can generally file an amended return to claim the money back, but only within the statute of limitations, which for a refund is usually three years from when you filed the original return or two years from when you paid the tax, whichever is later. Miss that window and the overpayment is gone for good, no matter how clearly it was an error. So the first thing we do when we take on a trader with messy prior years is check which years are still open.

The most common recovery is a wash sale or reconciliation error that inflated a prior gain. Suppose two years ago your return reported 110,000 dollars of gain that was really trapped wash sale losses against a true economic net near 20,000 dollars. You overpaid federal tax on roughly 90,000 dollars of phantom income, and you overpaid Illinois on it too, about 4,455 dollars at the flat 4.95 percent. An amended federal return, Form 1040-X, corrects the federal number, and an amended Illinois return recovers the state overpayment, because Illinois starts from the corrected federal figure. That is real money back in your pocket for a year you already closed the books on.

Futures traders leave money on the table the same way. If a prior preparer reported your CME futures as ordinary short term gains on Schedule D instead of applying the 60/40 split on Form 6781, you paid more federal tax than the law required. On 100,000 dollars of futures gains, applying 60/40 rather than full short term treatment can save several thousand dollars, and an amended return within the window claims that back. There is also a limited 1256 loss carryback election that can apply a current year futures loss against 1256 gains in the three prior years, a refund tool a generalist rarely knows to use. You claim that carryback by amending the earlier gain years and carrying the current year 1256 loss back against them, and the IRS pays interest on a refund it holds too long, so a well documented claim can come back with a little extra on top of the tax, which for a Chicago trader with heavy CME volume can turn a losing year into a check.

Amending is not free of risk, because a Form 1040-X gets a closer human look than an original return, so it has to be right and well supported, not a hopeful guess. We only amend when the numbers clearly favor it and the records back the change, and we file the federal and Illinois amendments together so the state refund follows the federal correction. We also fix whatever caused the error going forward, since recovering a refund once is good and never overpaying again is better. That work runs through our individual tax return service, the amended return rules come from the IRS guidance on amended returns, the futures treatment from the IRS Form 6781 material, and the state refund follows the rules of the Illinois Department of Revenue.

This is the part traders forget until a second notice arrives, this time from Springfield. Illinois builds its individual income tax on your federal taxable income, so almost any change the IRS makes to your federal number flows straight through to your Illinois return. Illinois and the IRS also share information, so when the IRS adjusts your federal return, the state usually finds out, and it expects you to report the change and pay the matching state tax. A day trader who settles a federal notice and thinks the matter is closed can get an Illinois bill months later for the state tax on the same adjustment, plus interest.

Put a number on it. Say the IRS adjusts your federal return to add 30,000 dollars of income, whether from a disallowed deduction, a reclassification, or a wash sale correction. At the Illinois flat 4.95 percent, that 30,000 dollars carries about 1,485 dollars of additional state tax, and it lands whether or not you remembered Illinois existed. Illinois generally asks you to file an amended state return within a set number of months after the federal change becomes final, and skipping it lets the state assess the tax with interest running from the original due date, which quietly enlarges that 1,485 dollar adjustment by the time the notice arrives. On a larger 80,000 dollar federal adjustment the Illinois piece alone is about 3,960 dollars at 4.95 percent, so the state follow on is never an afterthought. The good news is that the reverse is also true. When a federal change reduces your income, such as an amended return recovering trapped wash sale losses, the Illinois tax comes down with it and you claim the state refund on the same corrected figure.

Because the two returns are joined at the hip, we never handle a federal notice in isolation for a Chicago trader. When we answer a CP2000 or defend an audit, we calculate the Illinois consequence at the same time, so you know the full cost or the full refund across both governments before you agree to anything. If the federal outcome raises your income, we prepare the Illinois amended return and get ahead of the state notice rather than waiting for it. If it lowers your income, we file for the Illinois refund alongside the federal one. Chicago itself adds no city income tax on trading income, so the state layer stops at the Illinois 4.95 percent, which at least keeps the follow on bill to a single rate.

The lesson is that a trader’s federal and Illinois returns move together, and treating them separately is how a second surprise bill happens. We keep them synchronized, report federal changes to Illinois on time, and make sure a federal refund pulls an Illinois refund along behind it rather than being left unclaimed. That coordination runs through our individual tax return service, the federal side follows the IRS audit and adjustment process and the IRS CP2000 guidance, and the state tax that follows a federal change is set at the flat rate published by the Illinois Department of Revenue.

A notice questioning your mark to market election is a different animal from a CP2000, because it goes to whether the election was valid at all, not just to a number, and for a day trader the whole return can hinge on it. The Section 475(f) election lets a qualifying trader treat open positions as sold at year end fair value, turn trading gains and losses ordinary, and stop the wash sale rule from applying. It is powerful, which is why the IRS looks closely at whether it was made correctly. The election has an unforgiving deadline, generally the original due date of the prior year return, and it usually requires a proper statement and a Form 3115 to change your accounting method. Miss a step and the IRS can treat the election as invalid, which unwinds everything that depended on it.

The most painful version is a trader who claimed ordinary loss treatment under an election that the IRS says was never valid. Say you elected mark to market, had a rough year, and deducted a 120,000 dollar ordinary trading loss against your other income, which an ordinary loss lets you do without the 3,000 dollar capital loss limit. If the IRS finds the election defective, that 120,000 dollar loss reverts to a capital loss, deductible against capital gains plus only 3,000 dollars a year against other income, and the rest carries forward for years. The tax swing can be enormous, and because Illinois follows the federal number, the state consequence moves with it, though Illinois taxes the capital and ordinary character the same at 4.95 percent.

Defending the election means showing the IRS the paper trail, the timely election statement, the Form 3115 that changed the method, and the trader status that made you eligible in the first place, since only a qualifying trader can elect. If the election was genuinely made on time and correctly, the defense is a matter of producing the documents and the trade log that supports trader status. If there was a defect, the conversation shifts to relief, whether a late election or a method change can be salvaged, which is a narrow path but sometimes open. Either way, the answer starts with the records, not with an argument.

We keep the election statement, the Form 3115, and the supporting trade log together from the year the election is made, precisely so a later notice is a short exchange rather than a crisis. When a notice already questions an election, we assemble the proof, respond by the deadline, and handle the Illinois consequence in the same motion since the state follows the federal result. When we make the election for you in the first place, we file it correctly so it holds up years later. That work runs through our tax compliance service, the election and its mechanics are described in the IRS guidance on traders in securities and IRS Publication 550, and the state rate that follows the federal outcome comes from the Illinois Department of Revenue.
