KMA Accounting and Tax Services, located in Vienna, VA, provides tax filing services for businesses, including S-Corps and LLCs. Here’s a general overview of what each entity needs in terms of tax filing:
S-Corp Tax Filing:
An S Corporation (S-Corp) is a tax status that allows income, deductions, and credits to pass through to shareholders, avoiding double taxation. Here’s what needs to be filed for an S-Corp:
- Form 1120-S: This is the tax return for an S-Corp, where the corporation reports income, deductions, and other financial information.
- Schedule K-1: For each shareholder, the S-Corp provides a Schedule K-1, which reports their share of income, deductions, and credits from the S-Corp. Shareholders must include this information on their personal tax returns (Form 1040).
- State Filings: Some states may require additional forms or state income tax returns for S-Corps. In Virginia, for example, an S-Corp may need to file Form 502 (Virginia Corporation Income Tax Return) depending on its activity and income.
- Payroll Taxes: If the S-Corp has employees or pays the shareholder-employee a salary, the business must file Form 941 (quarterly) and issue Form W-2 at year-end.
- Estimated Tax Payments: Shareholders may need to make quarterly estimated tax payments on their share of the S-Corp’s income.

LLC Tax Filing:
A Limited Liability Company (LLC) can be taxed in different ways based on elections made (sole proprietorship, partnership, S-Corp, or C-Corp). For a basic LLC, here’s what you need to know:
- Single-Member LLC (Disregarded Entity): If the LLC is a single-member LLC and not treated as an S-Corp or C-Corp, it’s taxed as a sole proprietorship. The owner reports LLC income on Schedule C (attached to Form 1040).
- Multi-Member LLC (Partnership): A multi-member LLC is treated as a partnership unless it elects to be treated as an S-Corp or C-Corp. The LLC must file Form 1065 (U.S. Return of Partnership Income), and each member will receive a Schedule K-1 to report their share of the LLC’s income.
- LLC Taxed as an S-Corp or C-Corp: If the LLC elects to be taxed as an S-Corp, it must file Form 1120-S (as described above for S-Corps). If taxed as a C-Corp, it must file Form 1120.
- State Filings: Like S-Corps, LLCs may have state-specific filing requirements. In Virginia, LLCs must file an Annual Report with the Virginia State Corporation Commission and pay the associated fees.
- Self-Employment Taxes: If the LLC is treated as a disregarded entity or partnership, the owners will generally be subject to self-employment taxes on their share of the LLC’s income.
- Estimated Tax Payments: LLC owners may need to make quarterly estimated tax payments, especially if they expect to owe more than $1,000 in taxes when filing their returns.
