Business Tax Filing Services Backed by IRS-Authorized Professionals
Syntax Solutions provides business tax filing services for LLCs, S corporations, C corporations and partnerships across the United States. As an Authorized IRS e-file Provider, we prepare your federal and state returns and submit them electronically before each deadline.
Tax Filing Support for All the Returns Your Business Owes
Federal returns, state returns and annual compliance filings, handled by one team so nothing slips through the gap between two firms.
Business Tax Returns: 1120, 1120-S, 1065 and Schedule C
C corps, S corps, partnerships, multi-member LLCs and single-owner businesses. We prepare the federal return that matches how your business is taxed, issue the K-1s your owners need, and file the state returns that go with it.
Self-Employed and Owner Tax Returns
Freelancers, 1099 contractors and owners whose business income flows onto a personal 1040. We report it correctly, claim the deductions you qualify for, and make sure your personal return lines up with your business return.
Annual Reports and State Compliance Filings
Each state runs its own calendar for annual reports and franchise taxes. Miss one and you can face late fees, and some states will administratively dissolve your LLC. We track your dates and file before they hit.
Online Tax Filing Through IRS E-File
Syntax Solutions is an Authorized IRS e-file Provider. Your return goes to the IRS electronically, you get an acceptance confirmation back, and you never wonder whether a paper envelope made it.
Tax Season, Simplified. No Missed Deadlines. Filed Right, Filed on Time.
We pull your financial data directly from the accounting, payroll and tax platforms you already use, including QuickBooks, Zoho Books, ADP, TurboTax and TaxAct, to prepare accurate business tax returns. As an Authorized IRS e-file Provider, we file securely and on time while helping you claim every deduction you’re entitled to.

Online Tax Filing in Four Steps
You approve. We file.
Send Us What You Have
Upload last year's return, your books and your bank statements. If Syntax Solutions already does your bookkeeping, this part is done. If not, we review what you send and list exactly what's missing before any work starts.
We Prepare Your Return
A CPA or Enrolled Agent builds your federal and state returns around your entity type, the states you operate in, and who owns what.
You Review and Approve
You get the draft with a plain-English summary: what you owe, why, and what changed from last year. Ask anything. Nothing is filed until you say yes.
We E-File and Confirm
We e-file with the IRS and your state, and the acceptance confirmation goes into your dashboard. You keep proof of filing for as long as you're a client, ready for the day a lender or the IRS asks for it.
