§ 01 · What an S-Corp actually is

An S-Corp is a tax election — not an entity type.

Your underlying LLC or corporation files Form 2553 and elects to be taxed under Subchapter S of the Internal Revenue Code. Income flows through to the shareholders and is taxed once — bypassing the corporate-level tax of a C-Corp.

The lever is your two pay channels: a reasonable W-2 salary (subject to FICA + Medicare) plus distributions (no self-employment tax). Most owner-operators earning $80K+ net leave $8K–$15K/year on the table by staying Schedule C.

Worked example

Over 35 years of 1120-S work — the partner who runs the math is the partner you call when the K-1 lands. We've been preparing 1120-S returns since 1989; the math below is the same math we walk every prospective client through, with their own numbers.

Solo consultant · $180K net SE income on Schedule C

Self-employment tax — Schedule C ~$25,400
— If S-Corp had been elected —
$80K W-2 salary → FICA ~$12,240
$100K distribution → no SE tax $0
Savings, year 1 ~$13,160

Example only. Actual savings depend on your specific facts — reasonable comp varies by industry and role.

§ 03 · From the firm

The firm has been preparing 1120-S returns since 1989. Two offices, two principals, one specialty. We do not advertise volume — we advertise depth.

— KDM Accounting

§ 04 · Why KDM

The principles the firm is organized around.

Professionalism, responsiveness, quality. Not slogans — operational standards. Here is what each one means for a client engaging us.

§ 04 · 01

S-Corp specialist — not a generalist preparer

Two South Florida offices and three decades of S-Corporation tax practice. We are tax specialists for small to medium businesses — not generalists who file an S-Corp once a year.

§ 04 · 02

Specialist-led from day one

The specialist you meet in the scoping call is the specialist on your file. No bait-and-switch to junior staff after the engagement letter is signed.

§ 04 · 03

Same-business-day responsiveness

Phone and email reply within the business day, by default. Material questions reach a specialist inside the day — built into how the engagement is staffed, not promised in a marketing line.

§ 04 · 04

One firm across personal and entity

Bookkeeping, S-Corp tax, owner 1040, and IRS notice response — handled under one roof, by the specialist on your file. No re-explaining the business when April arrives.

Principle 01

Professionalism

Engagements are specialist-led from day one. Senior judgment on the strategy, the work product, and the relationship — not handed down to a junior after the sale.

Principle 02

Responsiveness

A scoped engagement defines who answers you and how fast. Same-business-day reply is the standard, not the headline. Material questions reach a specialist.

Principle 03

Quality

Defensible positions. Documentation that holds up to lender, IRS, and counsel scrutiny. Work that does not need re-work next quarter or next year.

§ 05 · Engagement process

From first call to scoped engagement in under a week.

Engagement of a tax and accounting firm ought to feel like engagement of professional services — clean scope, written terms, specialist accountability. Here is what that looks like with us.

§ 05 · 01

Scoping call

A 30-minute call with the specialist who would lead the engagement. We discuss your situation, the specific outcomes you need, and whether our practice is the right fit. If it is not, we say so and point you elsewhere.

Day 0

§ 05 · 02

Engagement letter

A written scope, deliverables, cadence, and flat fee. No hourly drift on open-ended work. Bookkeeping engagements run month-to-month; tax preparation and one-off services are flat-fee.

Days 1–5

§ 05 · 03

Onboarding and delivery

Secure portal access, document collection, and the first cadence of deliverables. The same specialist remains on your file year over year — you do not re-tell the story to a new face in twelve months.

Week 1 onward

§ 06 · The Florida advantage

South Florida headquarters. Engagements nationwide.

We engage S-Corporation owner-operators across the United States from our two South Florida offices. For clients with Florida operations or those relocating here, the local tax posture is genuinely different from the high-tax states they came from — and we work the difference into the planning at both the entity and owner level.

0%

state income tax (individual)

A favorable tax environment for owner-operators

Florida levies no individual income tax. For owner-operators of pass-through entities (S-corps, LLCs taxed as partnerships, sole proprietors), the entire bottom-line distribution flows to a 0% state rate. The structuring decisions we make on the corporate side compound this advantage.

5.5%

corporate income tax

Among the lowest C-corporation rates in the country

Florida's 5.5% corporate income tax applies only to in-state C-corporation income. For multi-state operations, apportionment math drives planning. We model both the federal and Florida posture together so the structure is built once and built right.

Nationwide

engagement footprint

Florida-headquartered, serving clients coast-to-coast

Most tax and bookkeeping work runs fully remote — the same specialist, the same deliverable cadence, regardless of where the entity sits. We file in every state with client nexus and handle the multi-state apportionment math that goes with it.

§ 07 · FAQ

Questions clients ask first.

The five most-common questions before we start an engagement. The full FAQ covers bookkeeping, tax, and IRS notice response in depth.

What kind of work do you do?

Three pillars under one roof: bookkeeping (monthly close, QuickBooks, reconciliations, financial statements — monthly from $325/mo or quarterly $525/qtr + $750 year-end for smaller corporations; payroll is a separate engagement); tax (Form 1120-S, K-1s, reasonable-compensation analysis, basis tracking, Schedule C, Form 1065, late-S-election rescue under Rev. Proc. 2013-30); and IRS notice response (CP2000, CP14, CP504 and similar routine notices for returns we prepared). We focus on small to medium businesses, with deep S-Corporation specialty.

Do you work with clients nationwide or just Florida?

Nationwide. We are headquartered in South Florida (Boca Raton + Fort Lauderdale offices) but most engagements run fully remote — secure portal, video calls, e-signature. We serve small to medium business owners across the United States.

How is reasonable compensation actually determined for an S-Corp owner?

We build a written reasonable-compensation memo using the IRS multi-factor test: training and experience, duties performed, time and effort, comparable salaries paid for comparable services, dividend history, payments to non-shareholder employees, timing and manner of paying bonuses, and what comparable businesses pay. The memo lives in the file as documentation defending the salary chosen — if the IRS ever examines the return and challenges the wage-vs-distribution split, we have the analysis ready.

My LLC missed the 75-day window to elect S-Corp status. Is it too late?

Usually not. Under Rev. Proc. 2013-30 the IRS grants late-S-election relief up to 3 years and 75 days after the intended effective date, provided the entity has filed consistently as an S-Corp (or had reasonable cause for not filing). We prepare the Form 2553 with the late-election statement and shepherd it through processing.

What kind of firm are you?

We are a tax and accounting firm focused on small to medium businesses, with deep specialty in S-Corporation taxation. We are not a CPA firm — financial-statement assurance work is performed by state-licensed CPAs and is outside our practice scope. We are not an IRS-representation firm — for audit defense, collections, appeals, or Offers in Compromise, we refer you to a licensed Enrolled Agent or tax attorney. We do respond to routine IRS notices (CP2000, CP14, CP504, and similar) on tax returns we prepared.
