Corporate Tax Preparation

If you own a corporation, an S-Corp or a multi-member LLC, your business owes the IRS a return of its own, separate from yours. Corporate tax preparation in Coral Springs, FL is what we do for companies across Broward County: the right federal form for how you are actually organized, filed on the right date, with the Florida side handled at the same time.

Accounting Max Services, Inc. was founded in 2009, and the team behind it brings over 17 years of combined professional experience. Your return is prepared by Enrolled Agents (EA), enrolled to practice before the Internal Revenue Service, and by CPAs, in English or Spanish.

Which return your business has to file

The form follows your structure, not your size. If you are not sure which one is yours, that alone is worth a first meeting.

• C corporation — Form 1120.
• S corporation — Form 1120-S, plus a Schedule K-1 for every shareholder.
• Partnership or multi-member LLC — Form 1065, plus a K-1 for every partner.
• Single-member LLC — no separate federal return by default; the activity flows onto your personal return.

Federal deadlines, by entity type

There are two dates a month apart, and the earlier one is the one owners miss.

• Form 1120-S and Form 1065 are due "the 15 day of the 3rd month after the end of its tax year". For calendar-year filers the IRS gives the date outright: "the due date is March 16, 2026 (March 15th falls on Sunday)" (Instructions for Form 1120-S, 2025; Instructions for Form 1065, 2025).
• Form 1120 comes a month later: "Generally, a corporation must file its income tax return by the 15th day of the 4th month after the end of its tax year." One exception matters — "a corporation with a fiscal tax year ending June 30 must file by the 15th day of the 3rd month" (Instructions for Form 1120, 2025).

Form 7004 buys time to file, not time to pay: "The automatic extension period for time to file is generally 6 months" (Instructions for Form 7004, Rev. December 2025). Anything you owe is still due on the original date, and interest runs from there.

Florida corporate income tax: who actually owes it

Florida has no personal income tax, so pass-through owners file nothing personal with the state. The entity is a different question. "For taxable years on or after 1/1/2022, the tax rate is 5.5%", and before you apply it you "subtract an exemption ($50,000 as of December 31, 2015) to arrive at Florida net income" (Florida Department of Revenue, Corporate Income Tax).

• Corporations, and LLCs classified as corporations, file Form F-1120.
• An S corporation files in Florida only if it pays federal income tax on its Form 1120-S.
• An LLC treated as a partnership files the information return F-1065 "if one or more of its owners is a corporation".
• "A single member LLC disregarded for federal and Florida income tax purposes is not required to file a separate Florida corporate income tax return."

With a December 31 year end, the F-1120 is due "on or before the 1st day of the 5th month following the close of the tax year" — May 1.

What we need from you

A corporate return is only as good as the books behind it. Bring, or send securely:

• Year-end profit and loss statement and balance sheet.
• Bank and credit card statements for the full year, reconciled.
• Payroll reports, and the W-2 and 1099 forms you issued.
• Prior-year federal and Florida returns.
• Asset purchases, vehicle records and loan documents.
• Your Sales Tax returns for the year, if you collect it.

If that list makes you uneasy, that is the real work, and it is not a January problem. Clients on monthly bookkeeping arrive at filing season with the return already half written, and the financial statements a bank or a landlord will ask for exist as a by-product. Sales Tax runs on its own calendar and is filed separately; see Sales Tax filing.

What a late return costs

For an S-Corp or a partnership the penalty has nothing to do with tax owed. It is charged per owner, per month: "$255 for each month or part of a month (up to 12 months) the return is late... multiplied by the total number of persons who were shareholders" (Instructions for Form 1120-S, 2025), and the same figure per partner on Form 1065. Four shareholders, three months late, is $3,060 before any tax is calculated.

A C corporation is penalized on the money: "5% of the unpaid tax for each month or part of a month the return is late, up to a maximum of 25% of the unpaid tax", with a floor for a return "required to be filed in 2026 that is more than 60 days late" of "the smaller of the tax due or $525" (Instructions for Form 1120, 2025).

Corporate tax preparation in Coral Springs, FL, with an EA

An Enrolled Agent is licensed by the IRS and holds, in the IRS's own words, "unlimited practice rights": "unrestricted as to which taxpayers they can represent, what types of tax matters they can handle, and which IRS offices they can represent clients before." That matters after filing, not during it. If a notice arrives about a return we prepared, the person who prepared it can answer the IRS for you.

We are EAs and CPAs in one office, working in both languages, at 1700 N University Dr STE 210 in Coral Springs, and we file for businesses in Tamarac, Coconut Creek, Parkland, Margate and Fort Lauderdale as well.
