Formation & state registration- Partnerships should check state rules for whether a filing is required to form or to register (general partnership often forms by agreement but many states require filing for limited partnerships, LLPs, or to register as a foreign partnership). Use the relevant Secretary of State or state business filing office to register or file a Certificate of Limited Partnership/LLP if required.

Employer Identification Number (EIN) & federal IDs- Obtain an EIN for the partnership (required for federal tax filings, banking, and payroll).

Partnership agreement & governance- Draft a written partnership agreement that sets ownership, decision-making, profit/loss allocation, capital contributions, dispute resolution, and exit/dissolution terms (strongly recommended even where not required).

Federal tax reporting (IRS)- Partnerships file Form 1065 (U.S. Return of Partnership Income) annually as an information return; the partnership does not pay income tax but issues Schedule K-1 to partners reporting their shares of income, deductions, credits.- Partnerships that employ staff must comply with employment tax filings (Form 941 quarterly, Form 940 FUTA, deposit and reporting rules) and employer withholding where applicable.- Other federal filings may apply for international activities (Forms 8865, 5471, etc.).5) State compliance

tax returns, franchise taxes, and annual reports- States vary. Example: California requires partnership returns (Form 565) and limited partnerships may owe an $800 annual tax; states may require annual reports and/or franchise taxes. Foreign qualification is required where the partnership conducts business in multiple states and may trigger additional tax/filing obligations.

Registered agent & trade names- Most states require a registered agent and registration (or DBA/fictitious name filing) if using a trade name.

Licenses, permits, and local compliance- Obtain any industry-specific or local licenses/permits (city/county business licenses, professional licenses) before operating.

Sales tax nexus and payroll obligations- Determine sales tax nexus in states where sales occur and register with state tax agencies; withhold and remit payroll taxes for employees in applicable jurisdictions.

Beneficial Ownership Information (BOI) / Corporate Transparency Act (FinCEN)- FinCEN’s BOI rule underwent changes

interim final rule (March 26, 2025) revised the definition of reporting companies such that entities formed under U.S. law (domestic entities) were exempted from BOI reporting; foreign entities registered to do business in the U.S. remain subject to BOI reporting with deadlines noted by FinCEN.- Check FinCEN guidance for current rules and deadlines.10) Dissolution and closing filings- File final federal and state tax returns, notify state business filing offices and tax agencies, and file necessary dissolution or termination documents with the Secretary of State and state tax bodies.Practical next steps (action checklist for US business owners / LLC founders forming or managing a partnership)- Confirm entity type and whether the partnership needs to file with the state (general vs limited vs LLP/LP).- Get an EIN from the IRS.- Draft and sign a partnership agreement (use attorney for complex arrangements).- Register with state(s) where you do business; appoint a registered agent.- Determine state tax registrations (income/franchise, sales tax, employer withholding) and file for any required licenses/permits.- Prepare to file Form 1065 and provide Schedule K-1s to partners by applicable deadlines; set up payroll tax deposits and filings if you have employees.- Review FinCEN BOI guidance to confirm whether your partnership must file (note: as of FinCEN IFR March 26, 2025 domestic entities were exempted; foreign reporting companies retained reporting obligations). Confirm current status with FinCEN.- If operating in multiple states, consider foreign qualification and monitor multi-state filing and tax obligations.Sources and supporting verbatim excerpts(Each entry below is the source URL followed by verbatim excerpt(s) extracted from that page.)1) IRS — Partnerships: https://www.irs.gov/businesses/partnershipsExcerpts:- "A partnership is the relationship between two or more people to do trade or business. ..."- "A partnership must file an annual information return to report the income, deductions, gains, losses, etc., from its operations, but it does not pay income tax.

The majority of reporting companies must file their initial, updated or corrected reports by March 21, 2025."- "If your LLC, corporation, partnership, or nonprofit corporation conducts business activities in more than one state, you might need to form your business in one state and then file for foreign qualification in other states where your business is active. ...

Many state rules differ (filing names, fees, franchise taxes, reporting deadlines). For a full state-by-state breakdown, I can fetch the Secretary of State and tax office pages for each state you want to cover (e.g., CA, NY, TX, FL, IL, NJ, PA, GA, VA) and extract the specific filing names, fees, and deadlines.Recommendation / next tool use- If you want a blog post that includes detailed, state-by-state compliance bullets (specific filing names, fees, links and deadlines) for a set of states, I recommend specifying which states (or confirm you want the major states: CA, NY, TX, FL, IL, NJ, PA, GA, VA). I can then fetch each state's Secretary of State and Department of Revenue pages and produce precise, citation-backed state sections.
