FL Tax Law Specialist · Understand the traps and how to avoid them.
When computing a client's federal taxable income, the candidate stops at adjusted gross income and applies the standard deduction without first netting the qualified business income deduction under IRC §199A, or conversely claims the §199A deduction on wages the client earned as an employee rather than on qualified trade or business income from a sole proprietorship, partnership, or S corporation.
Candidates memorize the §199A percentage and threshold amounts but never build the deduction from its components (qualified business income, the W-2 wage limitation, the UBIA limitation, and the specified service trade or business phase-out), so they either omit the deduction entirely or apply it to the wrong income category. The deduction sits between AGI and taxable income, a step many candidates rush.
What to do instead
Practice a repeatable worksheet: identify each trade or business, classify it as SSTB or not, compute QBI after removing reasonable compensation and guaranteed payments, apply the greater of 50% of W-2 wages or 25% of wages plus 2.5% of UBIA when over the threshold, then aggregate and apply the overall taxable income limit. Run at least five scenarios that cross the threshold in both directions and one where the taxpayer is an employee only.
The candidate treats a partnership or S corporation as a separate taxpayer for federal income tax purposes and computes entity-level tax, or files the wrong return (Form 1040 instead of Form 1065 or 1120-S), or fails to include a separately stated item such as charitable contributions or §179 expense on the partner's or shareholder's Schedule K-1.
Candidates conflate the return-filing obligation with the tax-paying obligation. Pass-through entities file information returns but generally pay no entity-level federal income tax; the character of each item flows through to the owners. Mixing up the two leads to double taxation or omitted income.
What to do instead
Build a comparison table for sole proprietorship (Schedule C, no separate return), partnership (Form 1065, Schedule K-1, no entity tax), S corporation (Form 1120-S, Schedule K-1, reasonable compensation required), and C corporation (Form 1120, entity-level tax). For each entity type, list which items are separately stated and which are aggregated. Then trace one K-1 line by line onto a hypothetical Form 1040.
The candidate misses a procedural deadline by treating the three-year period for assessment under IRC §6501 as the only limitation period, ignoring the six-year period for substantial omission of income, the unlimited period for a false return or failure to file, and the separate periods for refund claims and for collection after assessment under §6502.
Candidates learn one number per topic and do not build a timeline of which period applies to which event. Exam items often hinge on whether the taxpayer filed, omitted more than 25% of gross income, or filed a fraudulent return, and each changes the answer.
What to do instead
Draw a single timeline from filing date through assessment, collection, and refund. Annotate each segment with its statute, trigger, and exception. Then work backwards from a fact pattern: identify the filing date, the omission percentage, and whether fraud is alleged, and select the period before computing any date.
When advising on representation, the candidate states that a CPA or enrolled agent may represent a client before the IRS in any matter without regard to the client's filing status or the practitioner's own compliance, or confuses a power of attorney with a tax information authorization and assumes Form 2848 permits the representative to endorse or cash a client refund check.
Circular 230 and the rules on practice before the IRS are dense, and candidates collapse several distinct authorities into one. The scope of representation, the difference between Form 2848 and Form 8821, and the limits on receiving refunds are frequent exam targets.
What to do instead
Memorize the practitioner categories and their limits, the distinction between limited and unlimited representation, and the specific acts a representative may not perform. Pair each rule with a one-line fact pattern so you can recognize the trigger. Review Circular 230 subpart B and the Form 2848 instructions side by side.
The candidate computes Florida corporate income tax by applying the 5.5% rate to federal taxable income without first adding back the Florida-specific adjustments, without subtracting the exemption, and without applying the alternative minimum tax or the apportionment formula where the taxpayer has Florida and non-Florida activity.
Florida starts from federal taxable income but then modifies it. Candidates who skip the addition and subtraction schedule, the $50,000 exemption, and the apportionment mechanics arrive at a number that looks plausible but is wrong on every component.
What to do instead
Work a full Florida corporate return from federal taxable income through adjustments, exemption, apportionment, and rate. Keep a one-page list of the Florida additions and subtractions and the apportionment factors. Verify the current rate and exemption against the Florida Department of Revenue's published guidance before relying on memory.
The candidate treats every sale of tangible personal property as taxable at the same rate and ignores that Florida sales tax applies at the state rate plus applicable county surtax, that the surtax generally does not apply to items taxed at the state rate above a statutory cap, and that many categories (groceries, prescription drugs, certain services, occasional or isolated sales) are exempt or treated differently.
Candidates learn the state rate and stop there, then apply it uniformly. County discretionary surtaxes, the single-item cap, and category-specific exemptions change the answer, and the exam tests whether the candidate knows when the surtax does and does not attach.
What to do instead
Build a matrix of transaction types with columns for state tax, county surtax, and the governing exemption or cap. Practice computing tax on a mixed basket of items, including one item above the surtax cap. Confirm current rates and the surtax cap with the Department of Revenue rather than relying on a remembered figure.
The candidate applies documentary stamp tax at one flat rate to every document, failing to distinguish the rate for deeds and other conveyances from the rate for promissory notes and written obligations to pay money, and overlooking the Miami-Dade County surtax on documents or the surtax on consideration for certain conveyances.
Documentary stamp tax uses different rates for different document classes, and county surtaxes add another layer. Candidates memorize a single number and misapply it, or forget that the tax attaches to the document rather than the transaction's economic substance.
What to do instead
Create a table of document classes with their statutory rates, the base each rate applies to, and any county surtax. Practice computing tax on a deed with consideration, a promissory note, and a document executed in Miami-Dade. Note which party is responsible for the tax and when the document must be stamped.
The candidate advises a client to skip the informal protest or the administrative appeal and go straight to court, or misses the window to file a protest after a notice of proposed assessment, thereby forfeiting the taxpayer's administrative remedies.
Candidates conflate the federal deficiency process with Florida's procedure and do not know the Florida timeline for responding to a proposed assessment, requesting an informal conference, or filing a petition for reconsideration. Missing the window is fatal to the client's position.
What to do instead
Map the Florida assessment and appeal sequence on one page: notice of intent to assess, the taxpayer's response period, informal protest, formal protest, and judicial review. Annotate each step with its deadline and the office that handles it. Compare this map to the federal sequence so the two do not blur.
The candidate computes a refund or credit without confirming the taxpayer's filing status and dependency determinations first, then discovers that the standard deduction, the child tax credit, the earned income credit, and the applicable brackets all change, and the original computation must be redone.
Filing status is the gate to nearly every other computation, but candidates treat it as a labeling step and jump to the numbers. Dependency tests (qualifying child versus qualifying relative, residency, support, joint return) are frequently tested and frequently missed.
What to do instead
Always resolve filing status and dependents before touching any number. Work through the qualifying child and qualifying relative tests as a checklist and write the conclusion at the top of the worksheet. Then compute the standard deduction, credits, and brackets using that conclusion, and re-verify the head of household and surviving spouse requirements.
The candidate assumes a Florida collection or enforcement action follows federal rules, or advises that a Florida taxpayer may simply wait out a levy or lien without requesting a hearing, without checking whether a collection due process right or a Florida equivalent applies, and without confirming the practitioner's authority to act.
Federal collection due process and Florida collection procedures are separate systems with different notices, hearing rights, and deadlines. Candidates who carry federal assumptions into a Florida question, or vice versa, give advice that is wrong on the applicable authority and may waive the client's rights.
What to do instead
Keep a side-by-side comparison of federal and Florida collection: the notice issued, the hearing or protest right, the deadline, and the office of jurisdiction. For each scenario, first identify which sovereign is acting, then apply that sovereign's procedure. Confirm the representative's authority before any contact with the agency.
