Entity Formation & Structuring for High Net Worth Individuals in Chicago

It starts with a boundary. The Reed Corporation is a CPA and tax firm. We do not practice law and we do not draft operating agreements. We do not file articles with the Illinois Secretary of State as a legal service, and we do not pretend that a tax opinion is a legal one. Your attorney does that work and should. What we do is the tax analysis that tells your attorney what to draft, run alongside your counsel rather than in place of them. Entity formation for high net worth clients in Chicago is a two chair job, and the chairs are not interchangeable. The lawyer owns liability protection and governance. We own the arithmetic of how the thing gets taxed for as long as it exists.

The federal menu is short, and the IRS business structures material lays it out. A sole proprietorship reports on Schedule C and pays self employment tax through Schedule SE. A partnership files Form 1065 and pushes income out to the owners on K-1s. An S corporation files Form 1120-S after an election made on Form 2553. A C corporation files Form 1120 and pays its own tax before anything reaches you. An LLC is a state law creature with no federal tax identity of its own, which is the fact people find hardest to accept, and it defaults to disregarded or partnership treatment unless you check a box on Form 8832 or elect S status.

The Illinois layer is what makes this a local question rather than a generic one. Illinois taxes individuals at a flat rate of about 4.95 percent rather than a graduated one, so the bracket games that drive entity choice in California or New York simply do not apply here. What does apply is the Personal Property Replacement Tax, and the Illinois Department of Revenue collects it on top of everything else. Partnerships and S corporations pay roughly 1.5 percent of Illinois net income. Traditional corporations pay about 2.5 percent. That is a real cost of choosing an Illinois pass through, it is charged at the entity level before a dollar reaches your personal return, and it is invisible in every generic online comparison of an LLC against an S corporation.

A worked example. A client planned an S corporation for a consulting practice expected to clear 900,000 dollars of Illinois net income. The replacement tax at 1.5 percent runs about 13,500 dollars a year at the entity level, on top of the 4.95 percent personal tax on the flow through income and the federal tax on all of it. Over ten years that is 135,000 dollars nobody had put in the model. The S election still won, because the self employment tax saved on the distribution portion was larger, but it won by about 34,000 dollars a year rather than the 47,000 dollars the client had been told by a calculator he found online. The corrected number changed his decision about a second entity he was considering, and that is the point of running the arithmetic before the filing rather than after it.

The common mistake is choosing the entity from a search result and asking the tax question afterward. By then the articles are filed, the EIN is issued, the bank account is open under the wrong taxpayer, and unwinding it costs more than getting it right would have. Bring the attorney and the accountant into the same room before anything gets filed. If you are weighing a structure right now, you can Request Private Consultation and we will run the real numbers with your attorney in the loop. A tax strategy consulting engagement that models the real numbers, backed by bookkeeping set up correctly from day one, means the structure fits the business instead of the business bending around a structure somebody picked in a hurry. The entity you form this year is one you will live inside for a decade, so the hour spent now is cheap.

Enough to change the answer, and it is the most overlooked number in entity formation for high net worth clients in Chicago. The Personal Property Replacement Tax is an Illinois tax on the entity itself. The Illinois Department of Revenue collects it and passes it to local governments, replacing revenue that disappeared when Illinois abolished the personal property tax in 1970. It has nothing to do with property you own, and nothing to do with anything you would find by searching for property tax. The name is a historical artifact of a constitutional change more than fifty years ago, and it fools people every year, including accountants who moved here from states with no equivalent. It shows up as a line on the entity return and a check that has to clear, and by that point the structure is already chosen.

The rates are about 1.5 percent of Illinois net income for partnerships and S corporations, with trusts in the same bracket, and about 2.5 percent for traditional corporations. There is no federal analogue, so nothing in the IRS business structures guidance mentions it, and nothing in the standard comparison of Form 1065 against Form 1120-S will either. It applies before the flow through income reaches your personal return, where the flat 4.95 percent then hits the same dollars again. That is not double taxation in the technical sense, because the replacement tax is deductible in computing the income that passes through, but the cash leaves either way.

A worked example that shows the size of it. Take two structures for the same 1,200,000 dollars of Illinois net income from an operating business. As an S corporation the replacement tax is about 18,000 dollars at 1.5 percent, and the remaining income flows to the owner and carries about 58,509 dollars of Illinois personal tax at 4.95 percent on the 1,182,000 dollars that survived, so roughly 76,500 dollars of Illinois tax in total. As a C corporation the replacement tax is about 30,000 dollars at 2.5 percent, the Illinois corporate income tax adds 7 percent on top of that, or about 84,000 dollars, and then any dividend paid out gets taxed to the owner again at the personal 4.95 percent. The C corporation costs more than 114,000 dollars of Illinois tax before a single dollar of dividend leaves the building, against 76,500 dollars for the pass through. Federal treatment then runs on top of both, and the 21 percent federal corporate rate is exactly what tempts people toward the C corporation in the first place.

The Form 8995 qualified business income deduction sits on the other side of that comparison, and it exists only for pass through income. A C corporation never touches it. A 20 percent federal deduction against 1,182,000 dollars of qualifying income, in a year where the wage and property limits allow the full amount, is worth more than the gap between the 21 percent corporate rate and the individual rates for most operating businesses. Form 8995-A runs the versions where those limits bind or where the business is a specified service trade, which is where a lot of Chicago professional practices land. That single item flips more entity decisions than any state rate does, and it is the item most often left out of the spreadsheet a client arrives with.

The common mistake is a modeling one and it runs in both directions. People who read about the 21 percent federal corporate rate and stop reading forget the second tax waiting on the dividend. People who choose the pass through without touching the replacement tax underprice it by roughly 1.5 percent of everything the business earns, forever. Get both numbers onto the same page before your attorney files anything. A tax strategy consulting model that runs your real income figures, supported by bookkeeping that can actually produce them, answers the question in an afternoon. Illinois rates have moved before and will move again, so treat the structure as something to review rather than something permanent.

The S election is the most common question in entity formation for high net worth clients in Chicago, and the mechanism behind it is simple enough to state in two sentences. Wages you pay yourself carry payroll tax. Distributions of the remaining profit do not. That is the entire engine, and Form 2553 is how you make the election, generally within two months and fifteen days of the start of the tax year you want it to apply to, though late election relief exists and gets used far more often than the deadline suggests. The entity then files Form 1120-S and hands you a K-1 for the flow through income.

The savings are real and they are bounded. Self employment tax runs 15.3 percent, made of 12.4 percent for Social Security up to the annual wage base plus 2.9 percent for Medicare with no ceiling at all, and Schedule SE is where a sole proprietor pays it. Once your wages clear the Social Security wage base, the only thing left to save on the distribution side is the 2.9 percent Medicare piece plus the 0.9 percent additional Medicare tax above the threshold. So the election is worth the most inside a band of income, not at every level, and at the very top the savings shrink against the fixed cost of running payroll all year.

Reasonable compensation is the constraint and it is not optional. The wage has to reflect what the work is worth. The IRS position, backed by a long line of cases, is that an owner performing services must be paid what a stranger would command for the same job, and paying yourself 30,000 dollars on 900,000 dollars of profit invites exactly the examination you would expect it to invite. Wages report on Form W-2, and the payroll returns run through Form 941 quarterly and Form 940 annually. There is no bright line percentage, which frustrates everyone who asks, and the defense is built on comparable pay data and hours you can point to.

A worked example, and the number surprises people. A Chicago consultant clearing 400,000 dollars of net profit as a sole proprietor pays self employment tax of roughly 34,000 dollars once the Social Security wage base cap and the Medicare layers are worked through. Convert to an S corporation with a defensible salary of 180,000 dollars and the payroll taxes on that wage run about 27,100 dollars counting both halves, so the federal payroll saving is only about 6,900 dollars, not the 30,000 dollars an online calculator implies. Then Illinois takes its share. The replacement tax at 1.5 percent on roughly 220,000 dollars of S corporation net income costs about 3,300 dollars a sole proprietorship never owed, and running payroll adds perhaps 2,400 dollars of administration. The net benefit lands near 1,200 dollars a year. At that income the payroll arithmetic alone does not carry the election, and the honest answer is that the case has to be made on the wage limit inside the qualified business income deduction or on retirement plan capacity instead.

The common mistake is the calculator. Every one of them shows the federal payroll saving, none of them show the replacement tax or the payroll administration, and none of them know anything about the reasonable compensation constraint that caps the saving in the first place. The second mistake is the opposite error, which is paying a salary so low it collapses under a single question from an examiner. Set the wage from comparable data and write down how you got there. Run the structure through tax strategy consulting with your real profit figure, keep the payroll and the books tied together through bookkeeping that reconciles to the returns, and the election either earns its keep or it does not. Either answer is fine. Guessing is not, and the guess compounds every year the entity stays alive.

More than the state rate does, and it is the reason a lot of Chicago structures look the way they look. The qualified business income deduction gives owners of pass through businesses a federal deduction of up to 20 percent of qualifying business income, computed on Form 8995 for simple cases and Form 8995-A when the limits apply. A C corporation filing Form 1120 gets nothing from it at all. That gap is the first thing to price, because at this income level the limits almost always bind and the generic advice almost always assumes they do not.

Two constraints matter above the income thresholds. The first is the wage and property limit, which caps the deduction at the greater of 50 percent of the W-2 wages the business paid, or 25 percent of wages plus 2.5 percent of the unadjusted basis of qualifying depreciable property. A business with high profit and no payroll can lose the deduction entirely on that test alone, which is a genuine argument for an S corporation paying real wages where a partnership paying guaranteed payments would not qualify, because guaranteed payments are not W-2 wages. The second constraint is the specified service trade or business rule, which phases the deduction out completely above the threshold for consulting, law, accounting, health, financial services, and a longer list besides. A Chicago professional practice earning 900,000 dollars typically gets zero, and no amount of restructuring fixes that, because the rule looks at what the business does rather than how it is organized.

A worked example. A client owns a distribution business rather than a service business, generating 1,000,000 dollars of qualifying income. Structured as a partnership paying the owner 300,000 dollars of guaranteed payments and no W-2 wages to anyone, the wage limit produces a deduction of zero, because guaranteed payments do not count as wages for this test. Restructured as an S corporation paying that same owner a 300,000 dollar W-2 salary, qualifying income drops to 700,000 dollars, 20 percent of that is 140,000 dollars, and the wage limit of 150,000 dollars no longer bites. The deduction lands at 140,000 dollars, worth about 49,000 dollars at a 35 percent federal rate. The Illinois replacement tax on the S corporation runs about 10,500 dollars at 1.5 percent, which is a real cost, and it is dwarfed by the federal deduction the structure unlocked.

Illinois does not follow the federal deduction. This is a federal deduction only, taken below the line on Form 1040, and Illinois starts from federal adjusted gross income rather than federal taxable income, so the flat 4.95 percent applies to the full amount regardless of what the deduction did federally. That is worth knowing, because it means the deduction is a pure federal play here, and the Illinois side of the entity decision has to be argued on the replacement tax and the personal rate alone. Advisers who trained in a conforming state get this backward often enough that it is worth checking.

The common mistake is assuming the deduction is automatic because a friend with a smaller business gets it without thinking about it. Above the thresholds it is anything but automatic, and it is the single item most worth designing before the entity is formed rather than after, because payroll structure and entity type are precisely what the tests measure. Model it against your actual income with tax strategy consulting, and keep the wage and property records clean through bookkeeping that can prove the numbers the form asks for. Congress has reshaped this deduction before and may reshape it again, so build a structure that stands on its own merits rather than one that depends entirely on a single provision surviving untouched.

The filing is the easy part. What follows is a set of small obligations that each carry their own penalty, and the weeks right after formation are when almost every avoidable problem gets created. Your attorney’s engagement ends when the Illinois Secretary of State accepts the articles. The accounting obligations start that same day, nobody hands you a checklist, and the penalties do not care that you were busy launching a business. This is the part of the work that looks clerical and is not, and it is where entity formation for high net worth clients in Chicago quietly goes wrong.

Start with the employer identification number. The IRS guidance on getting an employer identification number covers the application, and Form SS-4 is the form behind it. Every entity with employees needs one, and practically every entity with a bank account needs one. It should be issued under the right responsible party the first time, because correcting that afterward is a paper exercise nobody enjoys. The IRS starting a business material walks the same ground from the federal side and is worth twenty minutes of reading before the first bank appointment. A single mismatch between the name on the articles and the name on the EIN application produces notices for years.

Then the accounting method and the tax year, both chosen on the first return and both hard to change afterward. Publication 538 covers accounting periods and methods, and the choice between cash and accrual decides when income shows up for the rest of the entity’s life, which for a business carrying receivables at year end is not a small thing. Then payroll, if there are employees or an S corporation owner drawing a wage, which means Form 941 every quarter and Form 940 every year, with deposits on a schedule that begins with the first paycheck rather than at some later date of your choosing. Then Form 7004, the extension, which buys time to file and never buys time to pay. Illinois runs its own registration and its own replacement tax return alongside all of that, and the Illinois Department of Revenue does not learn about your new entity from the Secretary of State in any way you should rely on.

A worked example of what neglect costs. A client formed an S corporation in March, filed the election on time, and then let the first year run without payroll because the business was new and cash was tight. He took 240,000 dollars out as distributions and zero as wages. The late filing penalty on Form 1120-S alone runs about 245 dollars per shareholder per month, so a return filed five months late with two shareholders costs 2,450 dollars for nothing but lateness. The reasonable compensation exposure was the larger problem. Recharacterizing 150,000 dollars of those distributions as wages produced payroll tax of roughly 22,950 dollars, plus penalties and interest on deposits that were never made, and the cleanup cost more than the first two years of the election had ever saved. None of that was a hard problem. It was a calendar problem.

The common mistake is treating formation as an event rather than a start date. The entity exists now. It has filing obligations now. It needs a bank account that stays separate from your personal money, and books that begin on day one rather than at the first tax deadline. Set up bookkeeping the week the articles land, not the following March, and let tax strategy consulting put the compliance calendar in front of you before the first deadline goes past. The structure you build this year is the one that will hold your business for the next decade, so start it clean and it stays clean.
