Short answerThe constitution requires that a tax on or measured by income be at a non-graduated rate, so no legislature can bracket it. But it exempts the replacement tax from its own one-tax limit, and that costs a partnership or S corporation 1.5 percent of net income.
Key takeaways
  • The constitution requires a non-graduated rate, so brackets need an amendment, not a bill.
  • The individual rate has been 4.95 percent of net income since 1 July 2017.
  • A corporate rate may not exceed the individual rate by more than a ratio of 8 to 5.
  • Partnerships, trusts and S corporations pay 1.5 percent replacement tax on top.
  • Leisure and hospitality grew 1.1 percent while total state employment stayed flat.

Illinois is the only state in this run of state pages where the flat rate is not a policy choice. The state constitution requires that a tax on or measured by income be at a non-graduated rate, so no legislature can turn it into a bracket schedule without amending the constitution first. That sounds like unusually strong protection for a working guide, and in one respect it is. The catch is written into the same document. The constitution also carves out a second income-measured tax that is expressly excluded from its own one-tax limit, and a guide who forms a partnership or an S corporation pays it on top of the ordinary rate.

The rate is constitutional, not legislative

A tax on or measured by income shall be at a non-graduated rate.

The wording in article IX of the Illinois Constitution is short enough to quote in full and blunt enough that there is nothing to interpret. A tax on or measured by income shall be at a non-graduated rate. At any one time there may be no more than one such tax imposed by the state for state purposes on individuals, and one such tax so imposed on corporations. That is the whole of the operative rule. It is not a statement of preference and it is not a statutory rate that a future session can revise; it is a constitutional limitation, and changing it requires the amendment process rather than a bill.

What that gives a guide

Certainty about the shape of the tax, if not about the number.

The practical benefit is worth naming plainly, because it is different from what a low rate gives you. In most states in this series the risk is that a good season pushes a guide into a higher band, or triggers a phase-out, or crosses a threshold that reprices earlier income. None of that can happen in Illinois. There is one rate, it applies to the first dollar and the last one identically, and no amount of success moves you into a worse position. The legislature can still change the number, and has. What it cannot do without a constitutional amendment is make the number depend on how much you earned.

The current number

4.95 percent of net income, in force since 1 July 2017.

The Department of Revenue's rate table publishes the individual rate as 4.95 percent of net income, effective 1 July 2017. Trusts and estates pay the same 4.95 percent under the business income tax heading, and corporations pay 7 percent. Withholding on employee compensation runs at the same 4.95 percent, and the department notes it also applies to Illinois lottery winnings each time a single payment exceeds $1,000, for residents and nonresidents alike, and to other gambling winnings paid to an Illinois resident where federal withholding requirements apply. Pull the current figure from the department before filing, because the number has moved more than once even though its shape cannot.

The 8 to 5 ceiling on corporations

The corporate rate may not exceed the individual rate by more than a ratio of 8 to 5.

One more constitutional constraint sits alongside the non-graduated rule, and it links the two rates together. In any tax imposed on corporations the rate shall not exceed the rate imposed on individuals by more than a ratio of 8 to 5. Run the arithmetic on the published figures and the relationship is visible: eight fifths of 4.95 percent is 7.92 percent, and the corporate rate is 7 percent, comfortably underneath. That calculation is this page's own, not the state's. What it means structurally is that Illinois cannot raise corporate tax without either raising the individual rate or bumping into a ceiling, which ties the two together in a way most states do not.

The second income tax the constitution allows

A replacement tax, expressly excluded from the one-tax limit.

Here is the part that catches people. A separate section of the same article required the General Assembly to abolish all ad valorem personal property taxes and to replace the lost local revenue with statewide taxes imposed solely on the classes relieved of that burden. Then comes the carve-out: if any taxes imposed for those replacement purposes are taxes on or measured by income, such replacement taxes shall not be considered for purposes of the limitations of one tax and the ratio of 8 to 5 set out in the non-graduated section. So the constitution permits a second income-measured tax and exempts it from its own headline restriction.

What the replacement tax costs a guiding operation

1.5 percent of net income for a partnership or an S corporation.

The department publishes the rates. Corporations other than S corporations pay 2.5 percent of net income as personal property replacement tax. Partnerships, trusts and S corporations pay 1.5 percent. That second line is the one that reaches a working guide, because a guide who takes on a partner, or who elects S corporation treatment on the advice that it saves self-employment tax, has moved into a category carrying an extra 1.5 percent of net income at state level. A sole proprietor is not on that list. Confirm the current position with the department before restructuring anything, because entity choice here has a state cost that the federal analysis will not show.

Why that changes the entity conversation

The federal saving and the state cost run in opposite directions.

The usual argument for a guide electing S corporation treatment is federal: split the income between a reasonable wage and a distribution, and the distribution escapes self-employment tax. That argument is made without reference to any state. In Illinois there is a number on the other side of it, and 1.5 percent of net income is not trivial against a margin that is already thin. None of that makes the election wrong. It makes it a calculation with two sides rather than one, and a guide being sold the federal half alone is being sold half an analysis. Take proper advice before you elect anything.

Illinois builds on the federal number

The constitution expressly permits adopting federal law by reference, including future changes.

The same article contains a provision that explains why an Illinois return leans so heavily on the federal one. Laws imposing taxes on or measured by income may adopt by reference provisions of the laws and regulations of the United States, as they then exist or thereafter may be changed, for the purpose of arriving at the amount of income upon which the tax is imposed. The phrase or thereafter may be changed is doing the work. Illinois has constitutional permission to move with federal law automatically rather than re-enacting conformity each time Congress acts, which is why a change in a federal deduction can reach an Illinois return without any Illinois legislation at all.

What that means for a guide's deductions

The federal treatment of your boat, truck and gear largely settles the Illinois figure.

Because the starting point is a federally computed amount of income, the deductions that matter most to a guiding operation are fought on the federal return rather than the state one. The depreciation position on a hull, the treatment of a trailer, the expensing of client tackle: all of that determines the net income figure before Illinois applies a percentage to it. That makes the federal analysis in the resale side of a guide's kit and the cost structure in what a boat actually runs more consequential to an Illinois guide's bill than the state rate itself.

Uniformity, and what it rules out

Subjects within a class must be taxed uniformly, and allowances must be reasonable.

A neighbouring section adds a general rule for non-property taxes that is worth knowing exists. In any law classifying the subjects or objects of non-property taxes or fees, the classes shall be reasonable and the subjects and objects within each class shall be taxed uniformly, and exemptions, deductions, credits, refunds and other allowances shall be reasonable. That is a constitutional standard rather than a rate, and it is the kind of provision that gets argued about rather than applied mechanically. For an ordinary guiding operation it will never come up. It is here because it shows Illinois writing structural limits into its constitution where most states leave them to statute.

Only one such tax, at any one time

The constitution permits a single income tax on individuals, full stop.

The clause that follows the non-graduated rule is easy to skim past and does real work. At any one time there may be no more than one such tax imposed by the state for state purposes on individuals. That is a numerical limit rather than a rate limit, and it forecloses a whole category of move available elsewhere. Illinois cannot layer a surcharge on top of its income tax, cannot add a second levy aimed at high earners, and cannot do what several states in this series do, which is to bolt flat dollar recaptures or phase-outs onto a schedule. Whatever the state wants from income has to be collected through one tax at one rate. For a guide that is worth more than it first appears, because the machinery that catches people in other states simply has nowhere to attach here.

Withholding reaches past wages

The same 4.95 percent applies to lottery and certain gambling payouts, not just payroll.

The department's rate table sets out where withholding bites, and the list is broader than employee pay. The 4.95 percent is required to be withheld from employee compensation based on the number of allowances claimed, from Illinois lottery winnings each time a single payment is over $1,000, for both Illinois residents and nonresidents, and from other gambling winnings paid to an Illinois resident where those winnings are subject to federal income tax withholding requirements. None of that is a guiding obligation. It is included because it shows the shape of Illinois withholding: the state attaches its collection duty to the payer rather than the recipient wherever it can, which is the same instinct that puts a withholding duty on a guide the moment they put a deckhand on a payroll.

Two Illinois markets, one border

A big-water charter fleet and an inland river business, sharing nothing but a state line.

Opinion rather than evidence. The Lake Michigan operation sells a boat, runs crew, burns fuel by the hour and lives or dies on a window of a few months. The downstate river and reservoir work sells a guide, runs on a fraction of the fixed cost and stretches across a longer calendar even if the day rates are lower. Those two are not variations on a theme; they are different businesses with different break-evens, and a captain moving between them is starting over on pricing. The inland end looks closer to the economics in what bass work pays, while the lake end carries the fixed base described in what putting a boat on finance really involves. Anyone weighing the two should price the platform before the market.

The labour market is losing people

Employment fell in every month while the unemployment rate held at 5.1 percent.

Illinois household employment declined in each month of the first half of 2026, from 6,241.8 thousand in January to 6,194.3 thousand in June, a fall of over forty-seven thousand. The civilian labour force peaked at 6,571.0 thousand in March and fell to 6,524.0 thousand by June. The unemployment rate rose from 4.9 percent to 5.1 percent and then sat there for four consecutive months. Unemployment itself went from 318.7 thousand to 329.7 thousand, having peaked at 337.3 thousand in April. That table sits at the federal Economy at a Glance page for Illinois, extracted 22 July 2026.

The sector that books trips is the one growing fastest

Leisure and hospitality up 1.1 percent, against a state total that is flat.

The composition is the encouraging half. Leisure and hospitality employment rose from 602.7 thousand jobs in January to 610.9 thousand in June, with the twelve-month change moving from minus 0.7 percent through zero and up to plus 1.1 percent. Total nonfarm employment across the state was essentially flat over the same period at plus 0.1 percent. Meanwhile financial activities fell 3.3 percent, information fell 2.7 percent and professional and business services fell 1.0 percent. Construction grew 4.5 percent and mining and logging 4.3 percent. The part of the Illinois economy that buys guided days is doing better than the state as a whole.

Two readings of the same state

Fewer people working, and more of them working in hospitality.

Those two sections describe the same economy and point different ways, so it is worth holding both. Household employment is falling and the labour force is shrinking, which is a weak signal. Payroll employment is flat to marginally positive and the visitor-facing sector is growing faster than anything except construction, which is a better one for a charter operation specifically. The two series are collected differently and a divergence between them is not an error. What a guide should take from it is narrow: the customer base looks steadier than the state's overall employment picture, and neither series says anything about what those customers spend.

What none of these sources measures

Three documents, none of which was built to say what a captain earns.

A constitution sets limits on how taxes may be structured and never touches income levels. A rate table lists percentages by taxpayer category and does not ask what any category actually makes. An employment series counts 610.9 thousand leisure and hospitality jobs statewide, in which charter fishing does not appear as its own line and carries no earnings figure. Illinois also splits into two quite different guiding markets, the Lake Michigan charter fleet out of the Chicago area and the inland river and reservoir work downstate, and averaging those together would describe neither.

A short open-water window

Roughly spring to autumn on the lake, against twelve months of slip and storage.

Below this line there is no citation. The Lake Michigan season is the constraint that shapes an Illinois charter business, and it is short enough that the fixed costs dominate the arithmetic. A slip, winter storage, insurance and a payment do not pause when the lake does, which means the number of sellable days matters far more than the headline trip price. That is the calculation worked through in the honest count of a working year, and it is sharper here than in most states because the window is genuinely narrow rather than merely seasonal.

A six-angler boat is a different business

Party-boat economics reward filling seats, not raising rates.

Still opinion. A Lake Michigan charter priced per boat for up to six anglers behaves differently from a guide selling a skiff to one or two people. The revenue per trip is higher and so is the fuel, the crew and the insurance, so the margin is not obviously better, and the marketing problem changes shape: the operator is selling a whole boat rather than a seat, which means a half-full booking is a full-cost day. The cover for that kind of platform is priced closer to what is set out in what guide insurance actually costs than most first-year plans assume.

What the entity election costs at state level

Every figure below is invented illustration built to show how the replacement tax interacts with the flat rate. It is not an Illinois guide's tax position, it ignores the federal side entirely, and it is not a recommendation about entity choice.

Sole proprietor. Net income of $70,000. Individual income tax at 4.95 percent is $3,465. No personal property replacement tax appears on the department's list for a sole proprietor, so the state total is $3,465.

S corporation, same net income. The $70,000 still runs through to the individual return and carries the same $3,465 of individual income tax. On top of that the entity pays personal property replacement tax at 1.5 percent of net income, which is $1,050. State total $4,515.

The gap. $1,050 a year, before any federal saving is counted on the other side. The federal self-employment argument for the election may still win. The point is that it has to win by more than this, and the federal analysis alone will not show you the number. Work it with your own figures and current rates before deciding anything.

1.5%of net income is the personal property replacement tax charged to partnerships, trusts and S corporations, on top of the ordinary 4.95 percent. A sole proprietor is not on that list. It is a state cost of entity choice that the usual federal argument for an S corporation election never mentions.Source: Illinois Department of Revenue, Income Tax Rates

Building an Illinois number

Work the entity question before the rate question.

The rate is fixed and there is nothing to plan around in it, which frees a guide here to spend the planning effort where it actually matters. First, the entity: sole proprietor, partnership or S corporation, priced with the state's 1.5 percent alongside whatever the federal analysis says. Second, the federal deduction position, since that produces the net income figure Illinois then multiplies. Third, the ordinary season sum of days sold, rate charged and twelve months of cost. Tips sit outside that and behave differently, as the piece on gratuities sets out.

Illinois against the others

The most structurally locked-down rate here, with a second tax hidden behind it.

Set against Georgia, whose rate steps down only if three fiscal tests pass, Illinois offers certainty about shape and no schedule of reductions. Set against Connecticut, which stacks four adjustments on top of its table, Illinois has none: one rate, first dollar to last. Set against California, which charges an entity simply for existing, Illinois charges an entity for what it earns instead, which is at least proportionate. What a guide gives up for that simplicity is the low band a graduated state provides in a poor year. The operating side sits in the business end of guiding.

There is no trip price anywhere on this page. The percentages are constitutional limits and published tax rates, the dollar figures are a withholding threshold and invented arithmetic, and the employment counts describe whole industries across a state of more than six million workers. None of it is a day rate and none of it describes what any operation earns. The worked example compares two entity structures at state level only and deliberately ignores the federal side, which is where the argument for an election normally lives, so it is not a basis for choosing anything. Rates change even where the constitution fixes their shape. Confirm the current rate, the replacement tax position for your own entity and the treatment of your own income with the department, and take proper advice, before you file or restructure.

How this was checked

The constitutional provisions come from article IX of the Constitution of the State of Illinois as published by the Illinois General Assembly at ilga.gov/commission/lrb/con9.htm, read 27 July 2026. Quoted or closely paraphrased: section 3(a), that a tax on or measured by income shall be at a non-graduated rate, that at any one time there may be no more than one such tax imposed by the state for state purposes on individuals and one on corporations, and that a tax imposed on corporations shall not exceed the rate imposed on individuals by more than a ratio of 8 to 5; section 3(b), that laws imposing taxes on or measured by income may adopt by reference provisions of the laws and regulations of the United States, as they then exist or thereafter may be changed, for the purpose of arriving at the amount of income on which the tax is imposed; section 2, that classes for non-property taxes shall be reasonable, that subjects within each class shall be taxed uniformly, and that exemptions, deductions, credits, refunds and other allowances shall be reasonable; and section 5(c), requiring abolition of ad valorem personal property taxes with replacement revenue raised by statewide taxes on the classes relieved of that burden, and providing that where such replacement taxes are taxes on or measured by income they shall not be considered for the purposes of the one-tax limitation and the 8 to 5 ratio in section 3(a).

The rates come from the Illinois Department of Revenue income tax rates page at tax.illinois.gov/research/taxrates/income.html, read 27 July 2026. Taken from it: individual income tax at 4.95 percent of net income effective 1 July 2017; business income tax of 7 percent for corporations and 4.95 percent for trusts and estates; personal property replacement tax of 2.5 percent of net income for corporations other than S corporations and 1.5 percent of net income for partnerships, trusts and S corporations; and withholding at 4.95 percent, applying to employee compensation based on allowances claimed, to Illinois lottery winnings each time a single payment is over $1,000 for residents and nonresidents, and to other gambling winnings paid to an Illinois resident where subject to federal withholding requirements.

What is inference, and what is not claimed. The observation that eight fifths of 4.95 percent is 7.92 percent, and that the published 7 percent corporate rate therefore sits below the constitutional ceiling, is this page's own arithmetic on two published figures and is labelled as such in the body. The connection between section 5(c) and the personal property replacement tax rates published by the department is likewise this page's reading of two sources together, not a statement either source makes. No claim is made that any particular guiding operation should or should not elect a given entity form, and the worked example says in its own text that it ignores the federal side. No Illinois filing deadline, penalty, interest rate or estimated tax threshold is stated anywhere in this article, because no source covering those was read. No Illinois sales tax position for charter trips is claimed, and no licensing requirement is mentioned.

The labour figures come from the U.S. Bureau of Labor Statistics, Economy at a Glance: Illinois, at bls.gov/eag/eag.il.htm, data extracted 22 July 2026, seasonally adjusted, June 2026 preliminary. Household employment falling from 6,241.8 thousand to 6,194.3 thousand, the civilian labour force peaking at 6,571.0 thousand in March and falling to 6,524.0 thousand, the unemployment rate series of 4.9, 5.0, 5.1, 5.1, 5.1 and 5.1 percent, unemployment rising from 318.7 thousand to 329.7 thousand with an April peak of 337.3 thousand, total nonfarm employment of 6,164.4 thousand at plus 0.1 percent over twelve months, leisure and hospitality rising from 602.7 thousand to 610.9 thousand with its twelve-month change moving from minus 0.7 percent to plus 1.1 percent, and the twelve-month changes in financial activities, information, professional and business services, construction and mining and logging are all read directly off that table. The arithmetic on the fall in household employment is this page's own. That page publishes no occupational earnings for fishing guides or charter captains in Illinois.

The worked example is invented. It applies the published individual rate and replacement tax rate to a chosen net income to size the state-level difference between two entity forms. The operation does not exist, no federal amounts are modelled, and the comparison is deliberately incomplete.

Reading an Illinois year, in order

Why can't Illinois have tax brackets?

Because its constitution forbids them. Article IX states that a tax on or measured by income shall be at a non-graduated rate, and that at any one time there may be no more than one such tax imposed by the state on individuals and one on corporations. That is a constitutional limitation rather than a statutory rate, so making the tax graduated requires the amendment process rather than legislation. The practical effect for a guide is that no good season can push you into a worse band, because there is no other band.

What is the rate?

4.95 percent of net income for individuals, in force since 1 July 2017. Trusts and estates pay the same 4.95 percent under the business income tax heading and corporations pay 7 percent. Withholding runs at 4.95 percent too, and the department notes it also reaches Illinois lottery winnings each time a single payment exceeds $1,000, for residents and nonresidents alike, and other gambling winnings paid to an Illinois resident where federal withholding requirements apply. Check the current rate for your own filing year.

What is the 8 to 5 ratio about?

It ties the two rates together. The constitution says a tax imposed on corporations shall not exceed the rate imposed on individuals by more than a ratio of 8 to 5. On the published figures, eight fifths of 4.95 percent is 7.92 percent and the corporate rate is 7 percent, so it sits underneath the ceiling. That arithmetic is this page's own rather than the state's. Structurally it means Illinois cannot raise corporate tax far without also raising the individual rate, which is an unusual linkage.

What is the personal property replacement tax?

A second income-measured tax that the constitution specifically permits. Article IX required the abolition of ad valorem personal property taxes and the replacement of the lost local revenue with statewide taxes on the classes relieved of that burden, then added that where such replacement taxes are measured by income they are not counted for the purposes of the one-tax limit or the 8 to 5 ratio. So the same document that forbids a second income tax makes an exception for this one.

Does it apply to me?

It depends entirely on your entity. The department publishes the rates as 2.5 percent of net income for corporations other than S corporations, and 1.5 percent for partnerships, trusts and S corporations. A sole proprietor does not appear on that list. So a guide who takes on a partner, or elects S corporation treatment, moves into a category carrying an extra 1.5 percent of net income at state level. Confirm the current position with the department before restructuring anything.

So is an S corporation election still worth it?

That is a two-sided calculation and most people are only shown one side. The usual argument is federal: split income between a reasonable wage and a distribution so the distribution escapes self-employment tax. That argument is made without reference to any state. In Illinois there is 1.5 percent of net income on the other side of it, which is not trivial against a thin margin. None of that makes the election wrong. It means it has to win by more than the state cost, and the federal analysis alone will not show you that number.

Why does my Illinois return follow my federal one so closely?

The constitution permits it explicitly. Laws imposing taxes on or measured by income may adopt by reference provisions of the laws and regulations of the United States, as they then exist or thereafter may be changed, for the purpose of arriving at the amount of income on which the tax is imposed. The phrase or thereafter may be changed does the work: Illinois can move with federal law automatically rather than re-enacting conformity each time. So the depreciation position on your boat is fought federally, and Illinois applies a percentage to the result.

So what does an Illinois guide make?

No source used here reports it, and Illinois holds two quite different markets. The Lake Michigan charter fleet around Chicago sells a whole boat for up to six anglers on a season running roughly spring to autumn. The inland river and reservoir work downstate is a different business with different economics. Averaging them would describe neither. What is worth doing instead is working the entity question first, since the rate itself offers nothing to plan around.
