CPA of Denver prepares returns for Colorado LLC owners after confirming how the business is taxed. Your number of owners, elections and business activity determine whether preparation belongs on an owner return, partnership return or corporate return.
LLC Tax Preparation: Choose the Return Your Business Needs
| Your LLC’s tax treatment | Preparation route | Fee and scope |
|---|---|---|
| Individual-owned single-member operating business, no corporate election | Owner Form 1040 with Schedule C | From $595 for the defined cash-basis business scope. Rental activity uses a different route. |
| Multi-member LLC taxed as a partnership | Form 1065 and partner K-1s | $750 qualifying no-balance-sheet return; balance-sheet preparation from $1,499. |
| LLC with an effective S corporation election | Form 1120-S and shareholder K-1s | $750 qualifying no-balance-sheet return; balance-sheet preparation from $1,499. |
| LLC taxed as a C corporation | Form 1120 preparation | Quoted after review. |
These are starting points, not a classification determination or a quote for every LLC. Existing return history, ownership, special elections and the activity matter. See how LLC tax classification works and the IRS LLC classification guidance. For individually owned rental activity, review rental-property preparation.
What Records Does Your CPA Need for LLC Taxes?
- Prior business and owner returns, EIN information and any election acceptance letters.
- Current ownership details and changes during the year.
- Complete financial statements, general ledger and account reconciliations.
- Owner contributions, draws, distributions and loan records.
- Payroll, fixed-asset and depreciation information where applicable.
- State activity and prior state filings.
How LLC Return Preparation Works
- Confirm the current filing classification and return year.
- Review the records and identify missing information or corrective work.
- Agree the preparation scope, fee and secure submission process.
- Coordinate the entity and owner information needed for the accepted filings.
Unreconciled books, payroll corrections, missing basis history and ownership changes can require a separate quote. A balance-sheet return does not automatically include reconstruction. Request a scope review before paying if these issues apply.
Colorado Multi-Member LLC and Partnership Returns
When the LLC is taxed as a partnership, preparation can involve federal Form 1065, partner K-1s and the applicable Colorado DR 0106 filing. Review our Colorado partnership return service for the state/federal distinction and preparation options.
Should Your LLC Elect S Corporation Treatment?
Expected profit, owner services, reasonable compensation, payroll and administrative cost should be evaluated together. An election is not automatically beneficial. Explore S corporation election help; timely election preparation and late-election corrective work have separate scopes.
Preparation Only or Ongoing Business Advice?
Compare business and owner return preparation from $1,795 with annual advisory plans. For a focused classification or records question, the $350 CPA Consultation covers up to one hour total for review, preparation and a telephone call. Written reports and implementation require separate agreement.
Frequently Asked Questions
What tax return does an LLC file?
Ownership, elections and activity determine the route. Common returns include an owner Form 1040, partnership Form 1065, S corporation Form 1120-S or C corporation Form 1120.
Does the $750 fee apply to every LLC?
No. It is a limited preparation fee for a qualifying S corporation or partnership return, not a universal LLC fee. Review the return classification and complete eligibility conditions first.
Can you review prior LLC filings?
Yes. A separately defined review can examine return and election history and identify questions or corrective filings. Corrections are not automatically included in return preparation.
