WHAT'S INCLUDED

## Complete tax preparation, end to end

### Federal Business Tax Returns
We prepare Form 1120 (C-Corp), 1120-S (S-Corp), 1065 (Partnership), and Schedule C (Sole Proprietor). Every return is reviewed by a senior accountant before submission.

### State & Multi-State Returns
Operating in multiple states? We handle nexus analysis, state tax registrations, and returns across all 50 states plus DC. We track filing deadlines so you never miss one.

### Quarterly Estimated Taxes
We calculate and prepare your quarterly estimated payments (Form 1040-ES or 1120-W) so you never face underpayment penalties. We remind you before each deadline.

### Sales Tax & E-commerce Compliance
Post-Wayfair, economic nexus rules can create surprise sales tax obligations. We track your thresholds, handle registrations, and file returns in all required states.

### Deduction Maximization
Our team proactively identifies every legitimate deduction — Section 179 expensing, bonus depreciation, home office, vehicle, retirement plan contributions, and more.

### IRS E-filing & Confirmation
All returns are prepared for electronic filing and signed off by your designated preparer. E-file confirmation typically follows within 48 hours of submission; we track acceptance and notify you immediately.

## How we prepare your tax return
01

### Document Collection
We send you a tailored document checklist by email. Share your documents securely — bank statements, 1099s, prior returns, receipts. We follow up proactively on anything missing.
02

### Accountant Review & Preparation
Your dedicated accountant reviews everything, identifies deductions, and prepares the draft return. Complex situations are escalated to senior reviewers with specialty expertise.
03

### Quality Control Check
Every return goes through a second-reviewer QC process before it reaches you. We check for accuracy, missed deductions, and state-specific requirements.
04

### Client Review & Approval
You receive the draft return with a clear summary of key numbers, estimated tax due/refund, and any notes. We walk you through it on a call if you'd like.
05

### E-filing & Confirmation
Once approved, your return is finalized for filing by your designated licensed preparer. You receive IRS acceptance confirmation within 48 hours, along with a copy of the filed return for your records.
