The typical cost to file Form 1120S varies widely depending on whether the business owner files themselves, uses online software, or hires a CPA. Price drivers include return complexity, number of shareholders, and state tax requirements. This article provides practical cost ranges in USD and practical factors to consider when budgeting.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Self-file (free software, zero CPA) | $0 | $0 | $0 | Only if no software fees and no professional help. |
| Tax software (online, per return) | $0 | $40 | $260 | Most programs range $40–$200; some add e-file charges. |
| CPA or enrolled agent (preparation) | $450 | $900 | $2,000 | Complex returns or multiple schedules raise costs. |
| State returns (if needed) | $0 | $50 | $300 | Some states require separate filings; professional fees vary. |
| Estimated additional filings (M-3, etc.) | $0 | $100 | $500 | Depends on asset levels and reporting requirements. |
Overview Of Costs
For a straightforward 1120S with one or few shareholders and simple deductions, total costs often range from $0 to $1,000 when using software, and $600–$2,000 when engaging a professional. The high end applies to more complex situations, such as multiple state filings, Schedule K-1 distributions, or detailed M-3 reconciliation. On a per-unit basis, expect roughly $0–$300 per state if separate state returns are filed, or $40–$200 per return when using software.
Cost Breakdown
This section breaks down where money goes when filing Form 1120S. The table below shows representative components, with assumptions for typical S-Corps (one to five shareholders) and standard payroll in the prior year.
| Materials | Labor | Software/Tools | Permits | Delivery/Disposal | Taxes |
|---|---|---|---|---|---|
| Tax software license or e-filing | Self-service time: 2–6 hours | $0–$200 | $0–$50 | $0 | Taxes included in state filings where applicable |
| CPA/EA preparation | 5–15 hours | Included in hourly rate | $0–$50 | $0 | Possible additional state tax charges |

What Drives Price
Key price drivers include shareholder count, state taxation, and reporting complexity. Larger S-Corps with many shareholders or intricate allocations raise compliance time and software tiers. The Form 1120S itself is simple, but accompanying schedules (M-1 adjustments, M-3 if required) and payroll data complexity increase the bill. One-cardboard threshold examples: ownership > 15 shareholders, and gross receipts exceeding thresholds may trigger state-level reporting, increasing total costs.
Common drivers include:
- Shareholder count: 1–10 vs. 11–100, affects K-1 preparation and review time
- Payroll complexity: number of employees and payroll frequency
- State filings: multi-state operations add annual state tax returns
Ways To Save
Budget-friendly tips can reduce the cost of filing 1120S. First, gather all financials and distribute profit allocations before engaging a preparer. Use reputable tax software for simple returns and compare quotes from CPAs who specialize in S-Corps. Consider bundling 1120S with other business tax filings to obtain package discounts. Delaying filing to avoid peak tax season can also yield savings.
- File electronically with software for basic returns
- Shop multiple CPAs for a written quote
- Provide clean records to minimize revision time
Regional Price Differences
Prices vary by region due to labor rates and local tax rules. In the Northeast, professional fees tend to be higher due to higher cost of living. The Midwest often presents mid-range pricing, while the Southeast can be slightly lower on average. Consumers in urban areas typically see higher software and service fees than in rural markets.
| Region | Typical Range (Total) | Notes |
|---|---|---|
| Northeast (Urban) | $700–$2,400 | Higher labor, state complexities |
| Midwest (Suburban) | $600–$1,900 | Balanced costs |
| South / Rural | $500–$1,500 | Often lower hourly rates |
Labor, Hours & Rates
Labor costs hinge on the preparer’s experience and the return’s complexity. Hours correlate with shareholder count, asset tallies, and required reconciliations. Typical CPA rates range from $150–$350 per hour, with total project time from 3–20 hours depending on data readiness and the number of schedules. Software-based filing reduces labor but adds per-return fees.
Additional & Hidden Costs
Surprises can occur beyond base filing fees. Some potential extras include state amendments, late-file penalties, rush processing surcharges, and additional schedules like Schedule M-3 for large or complex financials. If the company is subject to state franchise taxes or local filing requirements, those may add to the bottom line. Ensure any estimated quote includes all anticipated add-ons.
