Business Tax Filing (USA)

Common IRS forms include Form 1120 (C-Corporation), Form 1120-S (S-Corporation), and Form 1065 (Partnership). The specific form depends on your business entity type. C-Corporations file Form 1120 reporting taxable income at the corporate level. S-Corporations file Form 1120-S as pass-through entities, with income reported on shareholders' personal returns via Schedule K-1. Partnerships file Form 1065, distributing income to partners through K-1 schedules. Single-member LLCs typically report on Schedule C of the owner's Form 1040, while multi-member LLCs file as partnerships. We determine the correct filing status and forms during your consultation.

Yes — most states require filing based on income sourced or economic nexus in that state. If your business has physical presence (offices, employees, inventory) or significant sales in a state, you likely have filing obligations there. Many states use economic nexus thresholds (e.g., $100,000 in sales or 200 transactions) to determine filing requirements, especially for eCommerce businesses. Multi-state businesses must also handle apportionment (allocating income across states) and may owe franchise taxes or excise taxes in certain jurisdictions. We analyze your business footprint, determine where you have nexus, and manage all required state filings and compliance.

Typically quarterly using Forms 941 and 940, with annual W-2 and 1099 filings. Form 941 (Employer's Quarterly Federal Tax Return) reports employee wages, federal income tax withheld, and Social Security/Medicare taxes for each quarter. Form 940 (Federal Unemployment Tax) is filed annually. You must also file W-2 forms for employees and 1099-NEC/MISC for contractors by January 31st each year. Depending on your payroll size and deposit schedule, you may need to remit taxes semi-weekly or monthly via EFTPS. State payroll filings vary by jurisdiction. We manage the entire payroll tax cycle — from quarterly filings to year-end reconciliation.

Nexus means having sufficient business presence (sales, employees, or property) in a state that triggers a filing obligation. Physical nexus occurs when you have offices, warehouses, employees, or inventory in a state. Economic nexus is triggered when your sales or transaction volume exceeds a state's threshold (commonly $100,000 in sales or 200 transactions annually), even without physical presence. This is especially relevant for eCommerce and remote businesses. Post-Wayfair Supreme Court ruling, most states enforce economic nexus. We perform a nexus analysis for your business, identify where you owe sales tax, register you with the appropriate state tax authorities, and manage ongoing filing and remittance.
