- What a DBA/Trade Name/Assumed Name is — and what it does and doesn’t do - A DBA (also called fictitious business name, assumed name, or trade name) is a public-notice filing that lets an owner or entity operate under a name other than its legal name. It does not create a separate legal entity, does not by itself provide liability protection, and does not grant exclusive trademark rights. For name protection you must register a trademark at the USPTO (federal) or a state trademark where available. 2) Federal considerations every US business owner should know - EIN and IRS: Changing or adding a DBA generally does not require a new EIN; obtain or update EIN info per IRS guidance when your structure or tax responsibilities change (see IRS guidance and Form SS-4 instructions). Use the EIN and correct legal name when filing taxes and e-file returns. - Trademarks: A DBA filing is notice for business identity only — it does not clear or reserve trademark rights. Check the USPTO before investing in branding if you want exclusive national rights. 3) Common compliance steps (universal checklist) - Step 1 — Choose and verify the name: run state business-entity name search(s), local fictitious name searches and a USPTO trademark search. - Step 2 — Determine the correct office to file with: Secretary of State vs county clerk vs state Division of Corporations — this depends on the state and business type (see examples below). - Step 3 — Prepare and file the correct form and pay the fee (fees commonly range $25–$100; a few states like Florida list $50). Include required owner/entity info, principal business address, and counties where business will be conducted when asked. - Step 4 — Publication and affidavit of publication: if required in your state (e.g., California and Florida have publication/advertising rules in the county), publish in the designated local newspaper for required time and file an affidavit if the filing office requires proof. - Step 5 — Update banking, contracts, licenses, and tax registrations: open/update business bank accounts under the DBA, notify your bank and update license/permit records. Update IRS records if necessary (name control rules for e-file are important for corporate returns). - Step 6 — Monitor expiration and renew or re-file as required: some states have fixed terms (Illinois five-year renewal, Texas certificates include a stated term up to 10 years) — set calendar reminders. - Step 7 — Abandonment or amendment: when you stop using a DBA, file a statement of abandonment where required. If information in the filing becomes materially misleading (address, entity structure), file a new registration or amendment per state rules. 4) Representative state-specific highlights and practical notes (illustrative; emphasize to readers that rules vary by state and sometimes by county): - California (county-level filing; publication required): Fictitious business names are filed at the city/county level (not with the California Secretary of State). You must file within specified timelines (CalOSBA guidance notes filing within the first 40 days of operation or before expiration) and publish the statement once a week for four successive weeks in a county newspaper; file an affidavit of publication with the county clerk. County fees vary; check the county recorder or clerk website and use the CalGold tool to find local filing offices. - New York (Department of State certificate for entities; counties for sole proprietors/partnerships): Corporations, LLCs and other entities file a Certificate of Assumed Name with NY Department of State (DOS). Fees are shown on the DOS form pages (e.g., $25 for LLCs/Limited Partnerships; corporations may have additional county fees). General partnerships and sole proprietorships file business certificates with the county clerk. - Texas (mixed system; county vs Secretary of State distinctions): Sole proprietors and general partnerships typically file assumed name certificates with the county clerk where they maintain a business office. Corporations, LLCs, LPs, and other filing entities must file with the Texas Secretary of State. The SOS provides Form 503 and a $25 filing fee for assumed name certificates filed with the SOS; assumed name terms may be up to 10 years and must be refiled before expiration. Filing does not confer exclusive rights; multiple filings for the same name are possible and name conflicts are handled via private legal remedies (trademark, unfair competition law). - Florida (state filing on Sunbiz; advertising required): Florida requires fictitious name registration with the Division of Corporations (Sunbiz). The online registration fee is typically $50; the law requires the name be advertised at least once in a newspaper located in the county of the principal place of business (the online form certifies the name has been advertised). Sunbiz provides online filing, instructions and a searchable database. - Illinois (assumed name adoptions and renewals): Illinois allows LLCs and corporations to adopt assumed names via the Secretary of State; adopted assumed names have an effective period and are renewable — guidance indicates adopted assumed names are effective from filing until the first day of the company’s anniversary month in the next calendar year evenly divisible by five (a 5-year renewal cycle for most adoptees). Consult the ILSOS pages for the specific form and e-filing options. 5) Fees, timelines, and publication — typical ranges and examples - Filing fees are state- and office-dependent: many SOS filings are around $25 (TX, NY example lines), Florida is $50 for a fictitious name registration online; county fees vary widely (California counties typically $20–$50 or more). Publication costs (California, Florida, and some counties) are separate and depend on the newspaper chosen — these can add $30–$300 depending on circulation and the required run length. - Term & renewal: Some filings have explicit maximum terms (Texas up to 10 years), some are renewed every few years (Illinois - five-year renewal), and some remain effective unless abandoned or replaced (check the state form language). 6) Practical compliance checklist for blog readers (LLC founders and US business owners) - Before filing: name search — state SOS, county fictitious name searches (if the state uses county filings), and a USPTO federal trademark search. Consider domain name availability and branding. - File in the right place: county vs SOS vs state Division of Corporations depending on business type and state. Use state portals (Sunbiz, NY DOS, CA county clerk portals, Texas SOSDirect) for online filing where supported. - Comply with publication requirements where required; save affidavits and proof of publication for your records. - Pay attention to fees and request certified copies if you need documentary proof for banks or third parties. - Update bank accounts, licenses, permits, vendor/supplier contracts, and payment processors to accept the DBA name. - Track renewal dates, terms of the filing, and file abandonment/withdrawal when you stop using the name. - Consider registering a trademark if you need exclusive rights beyond the public-notice function of a DBA. - When in doubt about legal effect or contract-signing under a DBA, consult an attorney. 7) Recommended authoritative sources to cite in your blog (collected during research) - California guidance (CalOSBA): county-level filings and publication requirement — find local county clerk/recorder pages via CalGold for county-specific instructions and fees. - New York Department of State: Certificate of Assumed Name pages and fees/instructions for domestic and foreign entities. - Texas Secretary of State: Name filing FAQs, Form 503 (Assumed Name Certificate) and guidance on county vs state filing responsibilities, term/expiration rules, and fees. - Florida Sunbiz (Division of Corporations): Fictitious Name Registration instructions, filing portal, publication requirement, and fee schedule (online registration $50 listed). - Illinois Secretary of State: assumed name adoption guidance and renewal term (5year cycle language for LLC assumed names). - USPTO: trademark basics and the Trademark Registration Toolkit for readers who want national name protection. - IRS: EIN and Form SS-4 instructions (EIN rules; name-change vs new EIN triggers) and IRS guidance on name control for e-filing. - SBA: general guidance that DBA rules vary by state and localities and typical cost/time expectations. 8) Next recommended actions for me as the research coordinator (if you want the finished blog content): - I can draft the full blog post and newsletter using the structure above with: a) an opening explainer, b) the universal compliance checklist, c) state-specific sections for 6–10 commonly searched states (California, New York, Texas, Florida, Illinois, plus Pennsylvania, Ohio, Washington, Georgia, Arizona) with step-by-step filing actions and links to official filing pages and forms, d) a template DBA filing checklist and sample affidavit of publication language, and e) an FAQ covering EIN, bank accounts, and trademark considerations. - If you want exhaustive 50-state coverage, I recommend I run targeted extractions for the remaining states’ official filing pages (limit about 5 states per extraction call to collect forms, fees, publication rules, and renewal cycles) and then compile them into the blog.
