Business Tax Filing Starting at $100

Yes, filing is mandatory even with losses. Reporting losses can actually benefit you — business losses offset other income on your personal return. Not filing can result in IRS penalties starting at $205/month for certain forms.

Single-member LLCs: April 15th (Schedule C with personal return). Multi-member LLCs/Partnerships: March 15th (Form 1065). S-Corps: March 15th (Form 1120-S). We can file extensions if needed, but estimated taxes are still due on original dates.

We analyze your sales data across all marketplaces, determine your nexus in each state (typically $100K+ in sales or 200+ transactions), register your business, configure automated collection, and file every return on schedule.

You must file Form 5472 with pro-forma Form 1120 — even with zero US income. Penalty for not filing: $25,000 per form. If you have US-source income, Form 1040-NR may also be required. We handle all of this.

COGS, marketplace fees (Amazon referral, FBA fees), shipping costs, PPC spend, software subscriptions, home office, vehicle/mileage, professional services, insurance, warehouse fees, and equipment depreciation. We maximize every deduction.

If you expect to owe $1,000+ in taxes, the IRS requires quarterly payments (April 15, June 15, Sept 15, Jan 15). We calculate your payments, send reminders, and prepare vouchers so you avoid underpayment penalties.

Marketplaces issue 1099-Ks reporting gross sales — including shipping, sales tax, returns, and refunds. We reconcile your 1099-Ks against actual net income so you're not taxed on money you never earned.

General accountants and DIY software don't understand marketplace fee structures, FBA cost accounting, multi-state nexus, or 1099-K reconciliation. Our CPAs work exclusively with ecommerce sellers and know every deduction specific to your business.
