Business tax planning in Chicago for established owners
A Chicago owner comparing tax planning firms needs a clear account of the decisions, people and obligations the engagement will cover. A personal return, a partnership election and a city tax review can involve different records and professionals. A proposal should explain how those pieces connect before it promises a result.
Financial Sales Insider focuses on established business owners with annual personal income before tax of at least $500,000, preferably $1 million or more. Business revenue and company value are separate figures. This resource helps you define a useful planning assignment and describe the help you need.
Choose the team around the owner and the business
Start by naming the decision that brought you to the search. An equity partner joining another practice needs a different scope from a software business owner reviewing contracts or a practice owner changing compensation. Ask a prospective firm which comparable ownership situations it handles and who would lead your work.
Give each firm the same initial summary: entities, ownership percentages, owner residence, business locations, current bookkeeping arrangements and the decision date. Include what will change. A professional cannot assess a partner transition from the last personal return alone, and a business forecast without the owners' obligations leaves part of the cash requirement unexplained.
For a partnership, ask who gathers information from the other partners and reconciles the entity calculation with each owner's position. For an S corporation, ask how the professional evaluates compensation for an owner working in the business. The IRS reasonable compensation guidance makes the services actually performed relevant. A standard salary percentage is not an adequate explanation of your facts.
Ask how the 2026 partnership election is modeled
Illinois planning needs current state assumptions as well as a federal projection. The Illinois PTE publication describes the annual election for eligible partnerships and S corporations. Ask the professional to identify the entity, tax year and owners included in any proposed comparison.
There is an additional partnership-specific question for tax years ending on or after December 31, 2026. IDOR bulletin FY 2027-01 describes two partnership PTE tax-base methods, including a choice involving resident partners' full distributive shares. Ask which method the analysis uses and how partner residence affects it. This expanded choice should not be presented as an S corporation rule.
The useful deliverable is a comparison based on the actual partner group, with payment responsibilities and assumptions stated. An election discussion should also explain what information is still missing and who supplies it. A possible entity-level benefit does not establish every owner's final outcome.
Check Chicago software and lease responsibility
A Chicago engagement may need expertise beyond income-tax returns. Under the city's lease-tax definitions, nonpossessory computer use can raise local questions. Confirm the current code section with the adviser before relying on a contract classification.
Ask who reviews the users' locations, the access arrangement and any bundled services. The code includes a terminal-location rule, a mobile-device sourcing provision and an optional-service test. An invoice address alone may leave the professional without the facts needed for the review.
An initial records schedule can identify the contract, subscribing entity, user locations, billing periods, charges and vendor tax treatment. Ask the adviser to distinguish your responsibilities as a purchaser from any responsibilities as a provider. Do not assume that software-related receipts all receive the same treatment.
The code also has exempt lease provisions. A claimed exemption needs its conditions checked for the relevant payment periods. Request a written explanation of the conclusion, supporting evidence and any city guidance still needed.
Compare the work each proposal will deliver
Ask for an owner-and-entity projection tied to the books, a description of alternatives and an implementation schedule. For a partner change, that schedule might allocate information requests among the tax firm, bookkeeper and attorney. For a lease-tax review, it should identify who obtains contracts, assesses treatment and handles any filings.
Compare the same scope across proposals. Check whether personal returns, entity returns, local tax work, payroll changes and follow-up reviews are included or separately quoted. The business tax planning fees guide provides a broader comparison framework.
Check professional credentials through the appropriate issuing authority. Illinois license lookup helps with state license records. The IRS explains CPA, EA and other preparer qualifications. A credential and experience with your particular ownership decision are separate checks.
Questions to settle before you engage a firm
Does the tax professional need a Chicago office?
An office can help with meeting preferences, but it does not establish the required expertise. Ask how the team handles Chicago obligations, partner information and secure records, whether meetings are remote or in person, and who responds when the facts change.
What should I expect after the planning meeting?
Agree on the output beforehand. Useful work identifies assumptions, alternatives, responsible people and action dates. Ask which steps the firm will implement and which require your approval or another professional. A discussion does not itself change payroll, make an election or complete a filing.
Describe the business tax help you need
Tell FSI about your ownership role, entities, locations and the decision you want help assessing. An inquiry is a request to discuss fit. It does not confirm an appointment, an available local firm or a tax result.
Describe my business tax needs
CPA and EA firms can introduce their services and participation questions separately.
