How Is Child Support Calculated if You Own a Business in Michigan?

If you own a company in metro Detroit and a child support case is starting, you may fear that your income looks nothing like a paycheck and that a court will simply guess high. Understanding how child support is calculated if you own a business in Michigan starts with one fact: the state formula runs on net income, and for a self-employed parent that figure can include far more than the salary on a tax return. Hermiz Law is a Michigan divorce attorney for men helping business owners across Oakland, Macomb, and Wayne counties prove their real income instead of an inflated one.

Child support for a business owner in Michigan is the amount produced when the Michigan Child Support Formula is applied to a self-employed parent whose earnings come from wages plus the profits, fees, and benefits the business generates. The calculation sits inside the larger framework of child support in Michigan, which also covers medical support and child care. This page explains how a business owner’s net income is determined, which business income categories count, how deductions, depreciation, and deferred income are scrutinized, how courts use a company’s historical practices to test for hidden income, when a court may attribute potential income, what records to prepare, and how deviation, modification, and enforcement fit into the full picture.

Madana M. Hermiz is the founding attorney of Hermiz Law, a Troy, Michigan firm focused on divorce and family law throughout metro Detroit. She has represented parents in support disputes where a self-employed spouse’s true income was the central question. Her practice centers on measuring a business owner’s income by what Michigan’s formula and case law actually require, not by speculation about what a company could theoretically produce.

 How Michigan Calculates Child Support and Why Business Owners Are Different

Every child support calculation in Michigan, including interim orders and later modifications, must begin with the Michigan Child Support Formula (MCL 552.605(2)). The amount the formula recommends is presumed appropriate, and the court must order it unless it finds that applying the formula would be unjust or inappropriate (Calley v Calley, 197 Mich App 380 (1992); MCL 552.605(2)). A business owner starts at the same place as every other parent. The path to the income number that feeds the formula is simply much longer.

Under the formula, a parent’s obligation has three components: a base support obligation adjusted for parenting time, medical support obligations covering health care coverage and ordinary and extraordinary medical expenses, and child care expense obligations (2025 MCSF 3.01(A)). Michigan applies these rules in a gender-neutral way, so a father who owns a company is judged on the same income standards as any other parent, and understanding how parenting time works in Michigan matters because overnights directly adjust the base amount. A divorce lawyer for fathers in metro Detroit can make sure each component is built from accurate numbers rather than assumptions about what a business owner must earn.

The formula is required by statute to reflect the needs of the child and the actual resources of each parent (MCL 552.519(3)(a)(vi)). For a business owner, the phrase actual resources is where the work happens, because a company can deliver money to its owner in forms a wage earner never sees. Identifying those forms, and characterizing each one correctly, is the core of a self-employed parent’s support case.

 Net Income, Not Gross Pay

The Michigan Child Support Formula runs on net income, and the objective of determining net income is to establish, as accurately as possible, how much money a parent should have available for support. All relevant aspects of a parent’s financial status are open for consideration (2025 MCSF 2.01(B)). For a business owner, that means the court looks past the salary line to everything the company actually makes available, a point that matters even more for higher earners under the 2025 Michigan Child Support Formula rules for high-income parents.

Before the formula runs, the gross income of each party must be calculated, and the formula addresses the complexities that arise, including perks and in-kind income, capital gains, tips and gratuities, gifts that replace income, and imputed income (2025 MCSF 2.01 through 2.09). The income sources the formula counts may not match the taxable income categories the Internal Revenue Service recognizes, so a tax return is a starting point rather than the final word. A parent cannot shrink a support obligation by paying himself a modest salary while the company retains or reroutes its earnings.

 What Counts as Income for a Self-Employed Father

Every parent begins with the formula’s broad list of base income sources. Base income includes, among other categories, cost of living allowances, shift premiums, bonuses, trust fund payments, capital gains, rental income, gifts that replace income, employer contributions to retirement plans, and insurance or similar payments received as compensation for lost earnings (2025 MCSF 2.01(C)). A business owner starts from that same list and then adds the categories written specifically for self-employed parents.

Michigan’s formula treats a self-employed parent, a business owner, or a business executive differently from a wage earner because a company can pay its owner in many more ways than a paycheck. Under 2025 MCSF 2.01(E), a business owner’s income may also be derived from the following:

  • Distributed profits from the business.
  • Profit sharing.
  • Officer’s, management, or consulting fees.
  •  
  • Certain personal loans taken from the business.
  • Certain payments to friends or relatives made from the business.
  • Unnecessarily deferred or reduced income.
  • Certain pretax business deductions.

Two of these categories carry presumptions worth knowing. Undistributed profits of a company the parent owns are included as income unless the parent shows that the retained earnings are essential to the operation of the company (2025 MCSF 2.01(E)(4)(d)(i)). Personal loans from the business are presumed to be redirected income unless the owner shows a signed note with loan terms, a receivable on the company’s books, current regular payments, and interest and repayment terms that look like reasonable business practice (2025 MCSF 2.01(E)(4)(c)(i)).

The formula also counts spousal support a parent receives from someone who is not the other parent in the case (2025 MCSF 2.01(F)), which is one of several ways spousal support and alimony in Michigan can interact with a child support calculation. Means-tested sources such as Temporary Assistance to Needy Families, food stamps, the federal Earned Income Credit, and Supplemental Security Income are not counted (2025 MCSF 2.04(A)).

 How Deductions, Depreciation, and Deferred Income Are Scrutinized

Because the formula reaches certain pretax business deductions and unnecessarily deferred or reduced income (2025 MCSF 2.01(E)), a Michigan court examines whether each deduction genuinely reduces what an owner has available or merely moves income out of view. Tax returns are helpful for a self-employed parent but do not prove actual income for child support, since cash flow to the owner can be far higher than the adjusted income a return reports (2025 MCSF 2.01(E)(1)). Schedule C, business returns, balance sheets, income statements, and general ledgers all become evidence of what is truly available (2025 MCSF 2.01(E)(2)).

Depreciation shows how Michigan draws the line. In Riemer v Johnson, 311 Mich App 632 (2015), the court excluded depreciation taken by the plaintiff’s businesses from income because the depreciation was consistent with the nature of those businesses. The formula narrows the deduction further: only straight-line depreciation of tangible personal property, consistent with the nature of the business, may reduce income, while real estate depreciation is always added back, and depreciation on home offices, personal vehicles, and accelerated depreciation is added back as well (2025 MCSF 2.01(E)(4)(e)).

Deferred and reduced income receives the same scrutiny, and the word unnecessarily does the work. Prepaying next year’s expenses in a profitable year, cutting an owner’s salary without a business reason, or routing pay to friends and relatives can all be treated as income that remains available. Unless the business shows legitimate reasons for reductions in salaries, bonuses, management fees, or other amounts paid to a parent, the parent’s income may be based on a three-year average (2025 MCSF 2.01(E)(4)(d)). A fathers’ rights divorce lawyer helps a business owner show that a deferral or deduction served a genuine business purpose rather than an effort to suppress the number.

 When a Deduction Is Added Back

Whether a deduction is respected or added back turns on the facts of how the business runs, not on a blanket rule. Entertainment and travel expenses that are not in the nature of the business, and personal automobile costs paid through the company, are the kinds of deductions courts add back to income (2025 MCSF 2.01(E)(4)(e)). A deduction that reflects the ordinary, documented operation of the company is far more likely to stand, which is why the reasoning behind each deduction, and the records supporting it, carry real weight.

Whether a depreciation entry or a deferral is respected or added back can decide a large share of your support number. Call Hermiz Law at (248) 825-8042 to review how your deductions should be presented in an Oakland, Macomb, or Wayne County support case.

 Historical Practices and the Hidden-Income Question

A recurring dispute in a business owner’s support case is how to value income that flows through a closely held company. Michigan law grounds that analysis in how the business has actually operated, not in an outside opinion of how it could be run. Diez v Davey, 307 Mich App 366 (2014), makes the point directly: the trial court erred by calculating a father’s income from an expert’s business judgment about how his S corporation should be run, rather than from the corporation’s historical practices and whether the father used the corporation to hide income.

Courts still look at the whole financial picture. A judge is not strictly limited to a payer’s income and may consider the payer’s overall financial condition when deciding what is fair (Good v Armstrong, 218 Mich App 1 (1996)). In Stallworth v Stallworth, 275 Mich App 282 (2007), evidence that a parent kept large amounts of cash, drew checks on demand from a corporation, owned multiple companies, and lived a lifestyle far above his claimed income supported a higher income finding. Owners of substantial closely held companies see the same financial scrutiny in a high net worth divorce in Michigan, where business value and business income are examined side by side.

Clean, consistent records are a business owner’s strongest protection. A clear multi-year history of how profits were distributed, how the owner was paid, and how deductions were taken lets a court measure real income and answers the hidden-income question directly, without leaving room for an opposing expert’s theory of what the company could pay.

 When a Michigan Court Can Attribute Potential Income

A business owner cannot lower support simply by drawing less from a profitable company. When a parent is voluntarily unemployed or underemployed, or has an unexercised ability to earn, income includes the potential income that parent could earn, subject to that parent’s actual ability (2025 MCSF 2.01(G)). Michigan courts have long held that a parent who voluntarily reduces income can be ordered to pay support based on the unexercised ability to earn (Berger v Berger, 277 Mich App 700 (2008); Olson v Olson, 189 Mich App 620 (1991)).

The analysis is grounded in reality, not punishment. A genuine downturn, a lost contract, or a prudent business decision is different from suppressing a draw to game the formula, and a divorce and custody lawyer for men can marshal the financial history that shows which one actually happened.

 The Factors a Court Weighs Before Imputing Income

Potential income is never a number picked out of the air. Before finding an unexercised ability to earn, the court considers a defined set of factors (2025 MCSF 2.01(G)(2)):

  • Prior employment experience and history, including earnings history and reasons for changes.
  • Educational level, literacy, and any special skills or training.
  • Physical and mental disabilities that may affect the ability to work.
  • Availability for work, excluding periods when the parent could not work.
  • Availability of opportunities to work in the local geographic area.
  • Prevailing wage rates and the number of hours of available work locally.
  • Diligence exercised in seeking appropriate employment.
  • Evidence that the parent is able to earn the imputed income.
  • Personal history, including age, health, residence, and means of support.
  • The presence of the children in the parent’s home and its impact on earnings.
  • Whether income dropped significantly compared with the period before the case was filed.

A court that skips this analysis can be reversed. In Carlson v Carlson, 293 Mich App 203 (2011), the trial court abused its discretion by imputing income without assessing the formula’s factors and without determining whether the parent had the actual ability and likelihood of earning the imputed amount. Michigan law also respects prudent financial choices: in Clarke v Clarke, 297 Mich App 172 (2012), a parent’s decision not to take early Social Security retirement benefits was not an unexercised ability to earn, as long as the choice was financially prudent rather than intended to harm the other parent or the child.

Whether a court can attribute potential income to you turns on your company’s real history and your actual ability to earn. Call Hermiz Law at (248) 825-8042 to talk through the imputation factors before they are argued against you in a metro Detroit courtroom.

 Preparing Your Business Records Before a Support Case

Because Michigan measures a company by its historical practices and demands proof of net income, preparation often shapes the result more than argument. A self-employed father who arrives with organized, consistent records is positioned to prove his true income and to rebut an inflated figure. Involving a divorce attorney for dads early gives you time to assemble the documentation before positions harden, and the same records also drive how property division works in a Michigan divorce when the business itself is on the table.

The records that matter most in a business owner’s support case include the following:

  • Several years of business and personal tax returns, including all schedules.
  • Profit and loss statements, balance sheets, and general ledgers showing performance over time.
  • Records of how profits were distributed and how the owner was compensated.
  • Loan documents for any personal loans from the business, with payment history.
  • Support for each significant deduction and for every depreciation entry.
  • Bank and merchant statements that reconcile with the reported figures.
  • Contracts or correspondence explaining any drop in revenue or in the owner’s draw.

Work closely with your accountant, because a clear explanation of how the business operates and why deductions were taken helps a court separate legitimate practice from hidden income. Consistency across several years is persuasive, since a pattern that predates the case is hard to portray as a maneuver designed to lower support. Respond to discovery completely and on time, keep money communications factual and documented, and avoid restructuring compensation while the case is pending, because changes made mid-case invite the very suspicion you are trying to avoid.

 Medical Support, Child Care, and the Full Support Picture

Child support in Michigan is more than one base number. A support obligation includes payment for the general care and needs of the child, medical support, and child care expenses (2025 MCSF 3.01(A)). Medical support covers health care coverage and the division of premiums along with ordinary and extraordinary medical expenses, so a business owner should expect the order to reach these obligations on top of base support adjusted for parenting time.

Every component rests on the income findings discussed above, which is why an accurate net income figure protects the entire order rather than one line of it. An overstated income number inflates base support, the medical allocation, and the child care split all at once. Reviewing what you should know about child support during a Michigan divorce helps a self-employed father see how these pieces come together while the case is still pending.

 Deviation, Modification, and Changes in Business Income

A Michigan court may deviate from the formula only if applying it would be unjust or inappropriate, and the order must state the amount the formula would have produced, how the order deviates from it, the value of any property awarded in lieu of support, and the reasons the formula result would be unjust or inappropriate (MCL 552.605(2); 2025 MCSF 1.04(B)). Income disparity between the parents does not, by itself, justify a deviation. For a business owner, the path to a fair number almost always runs through an accurate income calculation rather than a request to depart from the formula.

Business income rarely stays flat, and support can change with it. The court may modify a support order as the circumstances of the parents and the needs of the children require, and the party alleging a change in circumstances carries the burden of proving a change that justifies modification. A change in the child support formula itself can justify a modification but does not require one. The process for modifying child support in Michigan applies whether an owner seeks relief after a real downturn or responds to a claim that business income has grown, and it applies during and after a divorce in Michigan alike.

Timing matters when income changes. Support is generally modifiable only from the date notice of the petition is given to the other party, so waiting to file leaves an owner paying on outdated numbers. One exception cuts the other way: a court may retroactively correct the amount if a party required to report income to the Friend of the Court intentionally misrepresents or fails to report it, which makes full and honest disclosure of business income very much in an owner’s own interest.

 How Child Support Is Collected and Enforced

Once an order is entered, payment generally flows through the Michigan State Disbursement Unit, and all support orders must provide for income withholding, which takes effect immediately unless the court makes specific good-cause findings or the parties reach a court-reviewed written agreement on an alternative arrangement. For an owner whose income does not arrive as a conventional paycheck, setting up a reliable, documented payment method matters, because an order that is not immediately withheld becomes subject to withholding once the payer falls behind by an amount equal to one month of support. Knowing what actually happens at the Oakland County Friend of the Court helps a business owner keep an ordinary cash-flow swing from turning into an enforcement file.

When payments are missed, Michigan’s tools are strong. A delinquent payer’s driver’s, occupational, recreational, or sporting licenses may be suspended, and contempt proceedings may follow where withholding is inapplicable or unsuccessful. A contempt order may issue if the court finds the payer has the capacity to pay some or all of the amount due through diligence or currently available resources, and the court may presume, absent contrary proof, that the payer has resources equal to one month of support. Clear records of what the business genuinely produced let you show the real limits of your ability to pay instead of leaving the figure to presumption.

 Frequently Asked Questions About Child Support for Business Owners in Michigan

 Is child support based on my salary or my whole business income in Michigan?

Michigan uses net income under the Michigan Child Support Formula, and for a business owner that reaches well beyond the salary line. Income can include distributed profits, profit sharing, officer’s, management, or consulting fees, commissions, certain personal loans and payments from the business, unnecessarily deferred or reduced income, and certain pretax business deductions (2025 MCSF 2.01(E)). The goal is to capture how much money you actually have available for support.

 Does business depreciation count as income for child support in Michigan?

Not automatically. In Riemer v Johnson, 311 Mich App 632 (2015), depreciation was excluded from an owner’s income because it was consistent with the nature of the businesses. Under the formula, only straight-line depreciation of tangible personal property consistent with the business may reduce income, while real estate, home office, personal vehicle, and accelerated depreciation are added back (2025 MCSF 2.01(E)(4)(e)).

 Can I lower child support by paying myself less from my business?

Not by simply suppressing your draw. The formula counts unnecessarily deferred or reduced income (2025 MCSF 2.01(E)), can base income on a three-year average when pay reductions lack a legitimate business reason (2025 MCSF 2.01(E)(4)(d)), and allows potential income when a parent is voluntarily underemployed, subject to actual ability (2025 MCSF 2.01(G)). A court can look past a reduced salary to what the company genuinely makes available.

 How does a Michigan court decide if a business owner is hiding income?

The court examines the company’s historical practices and whether the owner used it to conceal earnings. In Diez v Davey, 307 Mich App 366 (2014), the trial court erred by relying on an expert’s opinion of how an S corporation should be run instead of the corporation’s actual history and the hidden-income question. Consistent multi-year records showing how the business really operated are your strongest answer to a hidden-income claim.

 Can my child support change if my business income goes up or down later?

Yes. Support can be modified on motion of either party or the Friend of the Court as circumstances change, and the party alleging the change carries the burden of proving it. Because support is generally modifiable only from the date notice of the petition is given to the other party, filing promptly after a genuine drop in business income protects you from paying on outdated numbers.
