An LLC and an S corporation are not interchangeable tax terms. An LLC is created under state law, while its federal tax treatment depends on its ownership and any elections it has made. A single-member LLC is generally disregarded for federal income tax purposes unless it elects corporate treatment. A multi-member LLC is generally treated as a partnership unless it elects to be taxed as a corporation.
For Port Washington and other New York business owners, that distinction affects the return that must be filed, the records that should be prepared, and the questions that should be resolved before the filing deadline. This S Corporation and LLC tax preparation checklist can help organize the process before you meet with a tax professional.
1. Confirm the entity’s tax classification
Do not assume that forming an LLC automatically created an S corporation. Confirm how the business is treated for federal and New York tax purposes.
Useful records may include:
- Articles of Organization or Certificate of Incorporation
- Employer Identification Number confirmation
- Form 2553 acceptance notice, if an S corporation election was requested
- Form 8832, if the entity elected corporate classification
- New York Form CT-6 approval or related correspondence
- Ownership percentages and the dates ownership changed
A federal S election does not always settle the New York treatment. New York generally requires a separate S corporation election using Form CT-6 unless the corporation is subject to a mandatory New York S election rule. The facts should be reviewed rather than assumed.
2. Reconcile bookkeeping before preparing the return
The tax return should be based on complete, reconciled books rather than a collection of bank statements assembled at the last minute. At a minimum, review:
- Business bank and credit-card reconciliations
- Income recorded in the books compared with Forms 1099-K and 1099-NEC
- Accounts receivable and accounts payable, when applicable
- Payroll reports and payroll-tax filings
- Owner contributions, draws, distributions, and reimbursements
- Business loans and year-end balances
- Equipment and other fixed-asset purchases
- Inventory, if the business sells products
- Prior-year adjusting entries and beginning balances
Personal transactions should be identified and separated. If an owner paid a business expense personally, the records should show whether it was reimbursed, treated as a contribution, or handled another appropriate way.
3. Review owner payroll and S corporation distributions
An S corporation shareholder who performs services for the company may also be an employee. The IRS states that an S corporation must pay reasonable compensation to a shareholder-employee for services provided before making non-wage distributions to that person.
Reasonable compensation is not determined by one universal percentage. Relevant facts can include the owner’s duties, experience, time devoted to the business, comparable compensation, the work performed by other employees, and the source of the company’s revenue.
Before filing, compare:
- Forms W-2 and quarterly payroll filings
- Officer compensation recorded in the books
- Shareholder distributions
- Health-insurance premiums paid for more-than-2% shareholders
- Reimbursements and accountable-plan records
Large distributions combined with little or no officer compensation deserve review before the return is finalized.
4. Separate entity-level and owner-level items
S corporations and partnerships generally pass many tax items through to their owners, but the entity still has its own filing obligations. The business may need to issue Schedule K-1 information, maintain basis-related records, and separately report items that affect owners in different ways.
Gather information concerning:
- Ownership changes during the year
- Capital contributions and distributions
- Shareholder or partner loans
- Guaranteed payments to partners
- Health insurance and retirement-plan contributions
- State taxes and estimated payments
- Prior-year suspended losses or other carryforwards
Owners should retain basis information rather than relying only on the current year’s Schedule K-1.
5. Identify New York-specific filing issues
A New York S corporation may have a New York franchise-tax return and fixed-dollar minimum tax obligation. Partnerships and LLCs can have different New York filing and fee requirements depending on their classification, income, and activity.
Businesses operating in more than one state should also identify where employees worked, where customers were served, where property was located, and whether the company registered or filed returns outside New York. Remote work and online service do not automatically eliminate multistate tax questions.
6. Check filing deadlines and extensions
For a calendar-year S corporation, Form 1120-S is generally due on the fifteenth day of the third month after year-end. Partnerships generally follow a similar federal timetable for Form 1065. An extension provides more time to file, but it does not necessarily postpone every payment or information-reporting obligation.
Do not wait until the deadline to determine whether an election was accepted, payroll filings agree with the books, or missing records must be reconstructed.
7. Prepare questions before the tax meeting
- Whether the current tax classification still fits the business
- Whether payroll and owner distributions were handled consistently
- Whether estimated payments should change
- Whether bookkeeping should be updated monthly instead of reconstructed annually
- Whether a retirement plan or accountable reimbursement plan is appropriate
- Whether expansion, a new owner, financing, or a major purchase changes the tax plan
Entity selection and S corporation elections should not be made solely because someone heard that an S corporation always saves taxes. Administrative costs, payroll obligations, state treatment, profit level, and the owner’s individual circumstances all matter.
