Illinois governs executor compensation under 755 ILCS 5/27-2, which provides for "reasonable compensation" determined by the Probate Court. Illinois courts typically award fees in the range of 2% to 5% of the gross estate, with the percentage varying based on the size and complexity of the estate.

Smaller estates, proportionally, often yield higher percentage fees because the minimum administrative effort required creates a floor on what courts consider reasonable.

Illinois probate courts in Cook County and the Chicago metropolitan area may apply different benchmarks than rural downstate courts, reflecting differences in local fee norms and the complexity of matters commonly handled in each jurisdiction. Executors should research local court practices before finalizing a fee request, particularly for large or complex estates where the proposed compensation may attract scrutiny from beneficiaries or the court.

Illinois executor fees are governed by 755 ILCS 5/28-1, which authorizes reasonable compensation for the representative. Illinois Circuit Courts — Cook County (Chicago), DuPage, and Lake Counties handling the most cases — apply a reasonableness standard without a statutory fee schedule.

Executor fees in Illinois for a typical estate range from 2% to 3% of the gross estate based on local bar guidelines and court opinions. Illinois uses the term "independent administrator" when no court supervision is required, which is common for straightforward estates.

Small estates under $100,000 may use Illinois's small estate affidavit, bypassing executor fees. Illinois imposes a state estate tax with a $4 million exemption; executor fees are deductible administration expenses that reduce the taxable estate.

In Illinois, the court evaluates executor compensation against a multi-factor test. Common factors include the gross value of the estate, the number and nature of assets, whether the estate includes operating businesses or real property requiring active management, the duration of administration, and the personal representative's level of skill and experience.

While Illinois does not publish a fixed fee table, surveys and published court opinions suggest that fees in Illinois typically fall between 1.5% and 5% of the probate estate's value, depending on estate complexity and local court norms. Smaller estates tend toward the higher end of that range (as a percentage) because the minimum effort required to administer any estate creates a floor on reasonable compensation.

Fee norms can differ across Illinois's 102 counties. Urban courts with heavier caseloads may apply stricter scrutiny, while rural courts may rely more on local custom.

Illinois offers a simplified procedure for estates valued at or below $100,000, including a small estate affidavit option that may allow heirs to bypass formal probate entirely. For estates near this threshold, the executor fee calculation becomes especially important because the cost of administration relative to the estate's value determines whether formal probate or the simplified path is more cost-effective for the beneficiaries.

In a reasonable-compensation jurisdiction like Illinois, proactive documentation is essential. Personal representatives should maintain detailed time records from the day of appointment, categorize tasks by type (asset inventory, creditor claims, tax filings, distributions), and note any extraordinary circumstances that increased the difficulty of administration.

When drafting an estate plan in Illinois, consider including a compensation clause in the will that sets a baseline fee or references a specific calculation methodology. While the court can always adjust, a testamentary provision reduces ambiguity and signals the testator's intent, which many Illinois judges will respect absent unusual circumstances.

Illinois imposes a state-level estate tax with an exemption of $4,000,000. For taxable estates, executor fees are deductible as an administration expense, which can meaningfully reduce the overall tax burden.

The typical probate timeline in Illinois runs 6-18 months, though contested matters or estates with complex assets may take longer. Executor fees accrue over this entire period, which is why an accurate upfront estimate helps both the fiduciary and the beneficiaries plan for the duration of administration.

When multiple co-executors serve a Illinois estate, the question of how to divide compensation becomes more nuanced than in statutory-percentage states. Under Illinois's reasonable compensation framework, the court evaluates each co-personal representative's contribution individually.

If one co-executor handles the bulk of administration while the other plays a limited role, the court may allocate a larger share of the total compensation to the more active fiduciary.

Co-executors in Illinois should document their respective time and activities throughout administration. When the time comes to petition for fees, Illinois courts expect each co-personal representative to justify their share independently.

Without contemporaneous records, the court may default to an equal split — potentially over-compensating a passive co-executor at the expense of the one who did the work. To reduce future friction, consider including a compensation clause in the will that addresses the co-executor scenario directly, specifying whether each fiduciary receives independent compensation or shares a single pool.

Professional fiduciaries — such as bank trust departments or licensed professional executors — who serve alongside family co-executors in Illinois typically charge their standard institutional fee schedule. This can create tension when the total compensation exceeds what the estate would pay a single individual personal representative.

Address this dynamic at the estate planning stage by specifying in the will how professional and lay co-executor fees interact, and whether the estate is intended to bear the combined cost of both.

Because Illinois does not fix executor fees by statute, there is inherent room for negotiation between the personal representative and the beneficiaries — or between the personal representative and the estate's attorney. A fee agreement reached between the fiduciary and all beneficiaries can establish the compensation amount without court intervention, provided no interested party objects.

Fee expectations should be discussed early in administration — ideally at the first meeting with all interested parties — rather than deferred until the final accounting. Upfront clarity prevents disputes and allows the personal representative to make an informed decision about whether to serve.

If the anticipated compensation is insufficient to justify the time commitment, the nominated personal representative may decline the appointment, allowing the court to appoint an alternative who is willing to serve at the available fee level.

Written fee agreements are strongly recommended in Illinois, even when all parties appear to be in accord. The agreement should specify the compensation methodology (flat fee, hourly rate, percentage, or combination), the payment schedule (periodic draws vs.

single payment at closing), and any conditions that would trigger additional compensation (such as litigation, tax audits, or business operations). A clear written agreement protects the personal representative from surcharge claims and gives beneficiaries transparency into estate administration costs.

Standard personal representative compensation in Illinois — whether set by statute, court approval, or reasonable compensation analysis — covers the routine tasks of estate administration: gathering assets, paying debts and taxes, filing required court documents, and distributing the estate according to the will or intestacy statute. When administration demands services beyond this baseline, Illinois law provides a mechanism for the personal representative to seek additional compensation for extraordinary services.

Under Illinois's reasonable compensation framework, extraordinary services are typically factored into the overall fee petition rather than claimed separately. The court considers the totality of the personal representative's work — both ordinary and extraordinary — when evaluating whether the requested compensation is appropriate. Identifying and documenting extraordinary services distinctly strengthens any petition for higher-than-typical fees. Common extraordinary services recognized by Illinois courts include:

• Contested proceedings (will challenges, beneficiary disputes)
• Business management during administration
• Complex tax planning or audit defense
• Real property transactions requiring court oversight
• Multi-jurisdictional estate administration

Documentation is the key to securing extraordinary fee approval in Illinois. Contemporaneous time records should separate ordinary tasks from extraordinary services, with narrative descriptions that explain why each task was necessary and how it benefited the estate.

Courts are far more likely to approve extraordinary fees when the personal representative can demonstrate a direct link between the additional services and a measurable benefit — such as recovering assets, defeating an invalid claim, securing a favorable tax outcome, or achieving a sale price above appraised value. This calculator estimates standard compensation only — extraordinary fee projections require analysis of the specific estate's circumstances and should be discussed with a probate attorney.
