US business tax filing means more than transferring a trial balance into a form. It requires confirming your entity's correct federal tax classification, whether that's a C-corporation filing Form 1120 or an S-corporation filing Form 1120S, reconciling income and deductible expenses against your books, and coordinating any state-level filings that apply on top of the federal return. Livida's US business tax filing service is delivered remotely by our India-based team, an extension of the bookkeeping and payroll support we already provide to USA-based clients. Filing instructions and forms for both return types are published directly by the IRS.
Confirming Your Entity's Tax Status First
Before preparing a return, it's worth confirming exactly how your business is classified for federal tax purposes. A C-corporation pays tax at the corporate level and files Form 1120. An S-corporation, provided it has a valid election on file with the IRS, passes income through to shareholders' individual returns and files Form 1120S instead. Many LLCs, by default, file neither form since they're taxed as sole proprietorships or partnerships unless they've specifically elected corporate treatment. Getting this classification wrong at filing time can mean using the wrong form entirely, which creates more work to correct than confirming it upfront.
What Each Return Requires
- Form 1120 requires a full accounting of corporate income, deductions, and credits to arrive at taxable income and the corporate tax owed.
- Form 1120S instead calculates each shareholder's share of income, deductions, and credits to pass through to their individual returns via Schedule K-1, alongside confirming the company's S-Corp election remains valid.
- Both depend on accurate underlying books, since errors in expense categorization or income recognition flow directly into the figures reported on the return.
Coordinating State Filings
Federal filing is often only part of the picture. Depending on where a business operates, state-level corporate income tax, franchise tax, or other state filings may apply on top of the federal return, each with its own rules and deadlines. Livida reviews which state obligations apply to your business based on where you operate and coordinates those filings alongside the federal return rather than treating them as a separate afterthought.
How We Deliver US Business Tax Filing Remotely
Livida does not maintain a physical office in the United States. Our US business tax filing service is provided by our India-based team, working directly with clients online to prepare and file Form 1120 or 1120S, coordinate applicable state filings, and manage the underlying documentation, delivered remotely in the same way we support clients across every region outside India.
A typical engagement follows four steps:
- Confirm your entity's federal tax classification and tax year.
- Reconcile income and expenses against your bookkeeping records.
- Prepare the federal return, Form 1120 or 1120S, and any state filings that apply.
- Review with you, file, and keep the filed copies on record.
Why This Works Better Connected to Your Books
Because Livida already handles bookkeeping, accounts receivable and payable, and payroll filings including Form 1099, 940, and 941 for many USA-based clients, business tax return preparation draws on the same set of records maintained throughout the year rather than a separate year-end scramble to reconstruct them. That continuity reduces the back-and-forth that often slows down tax season and helps keep your federal and state filings consistent with each other. If your US business tax return is coming up, Livida's team can prepare and file it remotely as part of your existing accounting relationship.
In the filings we handle, the most common delay is an entity whose tax election was assumed rather than confirmed, so we recommend checking this before any return is prepared. For founders who are still choosing a structure, our post on a US LLC for non-US founders explains how LLC tax treatment can differ from a corporation.
US Business Tax Filing at a Glance
| Question | Short answer |
|---|---|
| Who it suits | C-corporations, S-corporations, and LLCs taxed as either |
| What we handle | Federal return preparation, state coordination, reconciliation |
| Typical documents | Books, prior returns, shareholder details, payroll records |
| What happens next | Filing, then planning for the next tax year |
Key Takeaways
- Confirm your entity's federal tax classification before anything else.
- C-corporations file Form 1120, and S-corporations file Form 1120S.
- Default LLCs file neither form unless they have elected corporate treatment.
- State filings, including franchise tax, often sit on top of the federal return.
- Returns built on year-round books are faster and more consistent.
Conclusion
A tax return is only as good as the classification and books behind it, however your business is organized. Settling both early makes filing season calmer and keeps your federal and state filings aligned.
