Business Tax Preparation in Miami, FL
Federal and Florida business returns prepared from reconciled books, with the Florida adjustments, the county property return, and the owners' returns handled.
Federal and Florida returns together. The federal return for your entity, the Florida corporate return where one is due, and each owner's personal return, prepared from the same books.
Florida's differences handled. Florida adds back federal bonus depreciation and does not follow several recent federal changes, so the Florida return needs its own adjustments.
The county filings as well. The tangible personal property return to the Miami-Dade Property Appraiser, filed each spring with the business returns.
Corviniti prepares business tax returns for companies in Miami and across Miami-Dade County, from our office in downtown Miami. We prepare S corporation, partnership, C corporation, and sole proprietor returns, the Florida returns that go with them, and the owners' personal returns. A CPA leads the team, the returns are prepared from reconciled books, and we work in English and Spanish.
Florida has no personal income tax, so the income of an S corporation, a partnership, or an LLC taxed as one is usually taxed only on the federal return. A C corporation files the Florida corporate income tax return, Form F-1120, and pays 5.5 percent on income above $50,000. That return starts from federal taxable income and then applies Florida's own adjustments, so the Florida income differs from the federal figure.

The Detail
The gaps, and how we close each one
Service 01
The returns we prepare
A Miami business can owe several different returns each year, depending on its entity and where it operates, and each one has its own due date.
How we handle it
We prepare the federal return for your entity: Form 1120-S for an S corporation, Form 1065 for a partnership or multi-member LLC, Form 1120 for a C corporation, and Schedule C for a sole proprietor or single-member LLC. On the Florida side, a C corporation files Form F-1120, an S corporation files it only when it owes federal tax at the entity level, and a partnership files Form F-1065 only when one of its partners is a corporation. A calendar-year partnership return to Florida is due April 1. We also prepare the tangible personal property return for the county, any returns owed to other states, and each owner's personal return, so the K-1s and the personal returns agree.
What you get: Every federal, Florida, and county return the business owes, prepared from the same books.
Service 02
The Florida corporate income tax return
A C corporation in Miami owes Florida tax at a flat rate, but the tax is calculated on a Florida income figure that is often different from the federal one.
How we handle it
The Florida corporate income tax is 5.5 percent of Florida net income above a $50,000 exemption. The return, Form F-1120, is generally due on the first day of the fifth month after the tax year ends, so May 1 for a calendar-year company, or 15 days after the federal due date if that is later. A June 30 year end that began before 2026 is due on the first day of the fourth month instead, so a June 30, 2026 year end is due October 1, 2026, and its extension runs seven months. An extension on Form F-7004 otherwise runs six months. It is valid only if it is filed, with the tentative tax paid, by the original due date, and it is void if that payment falls short of the tax on the return by more than the greater of $2,000 or 30 percent. A company that does business in several states apportions its income to Florida, and the Florida return starts from federal taxable income, then adds and subtracts the items where Florida law differs. We prepare the federal and Florida returns together, so the Florida adjustments are traced to the federal figures they come from.
What you get: A Florida corporate return with each adjustment traced to the federal figure.
Service 03
Where Florida does not follow the federal code
Florida adopts the Internal Revenue Code as of a fixed date each year and makes exceptions. A return prepared only from the federal figures will be wrong on the Florida side.
How we handle it
Florida adopts the Internal Revenue Code by a bill passed each year. The 2026 bill, HB 7031 (Chapter 2026-137), adopts the Code as in effect on January 1, 2026, but keeps five sections as they stood on January 1, 2025, before the One Big Beautiful Bill Act: bonus depreciation under section 168(k), research and experimental expenditures under section 174(a), the business interest limit under section 163(j), the entertainment and meal rules under section 274, and expensing under section 179. It also leaves out the new section 168(n) allowance for qualified production property and section 174A. Separately, Florida adds back federal bonus depreciation for property placed in service before January 1, 2027 and deducts it over seven years. Qualified improvement property is the exception: Florida recovers its bonus depreciation on the schedule the Code allowed on January 1, 2020. A C corporation affected by these rules recomputes federal taxable income for the Florida return and attaches a pro forma federal return. We keep a Florida depreciation schedule beside the federal one, so the adjustments are carried correctly each year.
What you get: A Florida depreciation schedule and conformity adjustments carried correctly each year.
Unsure last year's Florida return was right? Have a CPA review it before the next filing.
Florida taxes business equipment, furniture, and fixtures as tangible personal property, and the return is filed with the county property appraiser, not with the Department of Revenue.
How we handle it
Every business that owns furniture, equipment, computers, or fixtures in Florida files Form DR-405 with the county property appraiser by April 1. After the first return, the filing is waived in any year the property is worth $25,000 or less, and it is required again once the value is higher. Each return is eligible for an exemption of up to $25,000 of assessed value, and filing on time is how the exemption is claimed: a business that files late can lose it. Equipment that is fully depreciated for income tax is often still on the property tax roll at a value above zero, and assets that were sold or scrapped stay on the roll until they are reported as disposed. We prepare the return from the fixed asset records we keep for the income tax return, so the two lists agree.
What you get: A tangible personal property return filed on time, so the $25,000 exemption is kept.
Service 05
Owners and companies with income in other states
A Miami company with customers, employees, or owners in other states can owe returns in those states. Florida taxes a C corporation's income at 5.5 percent and does not tax individuals' income.
How we handle it
A Miami company files in another state when it has employees, property, or enough sales there, and each state sets its own threshold. A company that moved from New York files a final New York return for the part of the year it did business there, and may keep filing if it still has New York employees or customers above the state's threshold. Owners who moved during the year file part-year returns in their former state. We prepare the federal, Florida, and other state returns together, so each state taxes only the income it is entitled to.
What you get: Returns in every state where the company or its owners owe them.
Service 06
Business returns for Miami's main industries
The items that change a business return differ by industry.
How we handle it
Funds and advisory firms. We prepare the partnership or S corporation return, allocate income among the partners, and prepare the returns owners still owe in New York or another state.
Companies with foreign owners. A U.S. corporation that is at least 25 percent foreign-owned, or a U.S. single-member LLC owned by a foreign person, files Form 5472 with its income tax return for each year it has transactions with a related party, and we prepare the two together.
Restaurants and hotels. We claim the federal credit for employer Social Security tax paid on reported tips, depreciate the equipment and build-out, and reconcile revenue to the sales tax returns.
Real estate. We prepare returns for property-holding LLCs and partnerships, with depreciation, cost segregation, the passive activity rules, and 1031 exchange reporting.
Medical and professional practices. We plan owner compensation, retirement plan contributions, and equipment depreciation with the owners' returns.
What you get: A return prepared around the items that change your industry's tax.
Service 07
How the filing process works
A return prepared in a hurry from unreconciled books leads to amended returns and notices later.
How we handle it
If we keep your books, the return is prepared from books that are already reconciled, and the year-end work starts in January. If another firm keeps them, we review and correct the books before preparing the return. You receive one request for the documents we need, a draft return with a written explanation of the main items, and time to ask questions before anything is filed. We file the extension where one is needed, and we set the next year's estimated payments when the return is filed. Explanations are available in English or Spanish.
What you get: One document request, a draft with a written explanation, and a filed return.
FAQ
Frequently asked questions
When are business tax returns due in Florida?
The federal S corporation and partnership returns are due March 15 for a calendar year, and the federal C corporation return April 15. A calendar-year C corporation's Florida Form F-1120 is due May 1, or 15 days after the federal due date if that is later. A partnership that must file Form F-1065 files it by April 1. The tangible personal property return is due April 1, and the annual report to the Division of Corporations between January 1 and May 1.
Does my S corporation file a Florida return?
Usually not. An S corporation files Form F-1120 only in a year when it owes federal tax at the entity level, such as the built-in gains tax or the tax on excess net passive income, and Florida taxes only that income. In other years the income passes to the shareholders, and Florida does not tax it.
Do I need to file a tangible personal property return?
Yes, if the business owns furniture, equipment, computers, or fixtures in Miami-Dade. Form DR-405 goes to the Miami-Dade Property Appraiser by April 1, and filing on time claims the exemption of up to $25,000 of assessed value.
Can you prepare our New York returns as well?
Yes. Ro Sokhi is a CPA licensed in New York, and we prepare New York returns for Miami companies that still do business there and for owners who have New York income. We prepare the federal, Florida, and New York returns together so the figures agree.
Do you work in Spanish?
Yes. Our team works in English and Spanish, including the review of the draft return before you sign it.
Do you prepare returns for restaurants and bars?
Yes. The items that change a restaurant's return include the federal credit for employer Social Security tax paid on tips, depreciation on equipment and build-out, and cost of goods sold. We reconcile reported revenue to the sales tax returns filed during the year.
Do you prepare returns for foreign-owned companies?
Yes. A U.S. company with a foreign owner files additional federal information returns, and the penalties for missing them are large. We prepare them with the income tax return, from records kept during the year.
Do you prepare returns for management companies and advisory firms?
Yes. We prepare the partnership or S corporation return, allocate income among the partners or shareholders, and coordinate with each owner's personal return and any other state where an owner still files.
Do you prepare returns for real estate companies?
Yes. We prepare returns for property-holding LLCs and partnerships, including depreciation and cost segregation, the passive activity rules, and the reporting for a 1031 exchange.
