Everything we've learned about starting and running a US business — written down as we go. Plain-English guides on addresses, LLCs, taxes, and the paperwork nobody warns you about.
An LLC owner often manages three different names at once: the DBA (the trade name the LLC operates under), the business license (the operating authorization from the city, county, or state), and the trademark (the brand protection from USPTO or state). Each is a different legal instrument, each is filed in a different office, and each has its own address rule. This guide separates the three at the comparison level and points to deep-dive coverage in the dedicated guides.
An LLC and a partnership tax the same way at the federal level, so the choice comes down to liability, formation cost, and the operating agreement. For a two- or three-person active business, the partnership wins only in narrow situations: low-risk service work, zero-capital formation, and an explicit decision to accept unlimited personal liability. This guide separates General Partnership, Limited Partnership, and Limited Liability Partnership from the LLC, with the address slot for each structure.
An insurance agency formed as an LLC files three addresses with each Department of Insurance: the principal office, the designated responsible producer's affiliation, and the carrier appointment record. Address mismatches across these slots are a common source of license delay, and the rules vary state by state.
Form ADV Part 1A Item 1.F lists an RIA's principal office and place of business as a public IAPD record. The address rule shifts depending on whether the firm registers with the SEC or with a state securities regulator, and the slot decides where the firm appears on the regulator's record.

Section 83(b) is the IRS election a founder files within 30 days of receiving restricted equity to lock in the tax basis at grant. For LLC founders, the election interacts with profits interest safe harbors under Rev Proc 93-27, and the 30-day clock is unforgiving.
Series LLCs centralize one filing with internal cells. Holding company LLCs use a parent with separate subsidiary LLCs. The right structure depends on property count, investor stage, the state of operation, and how each address slot is assigned.
A property management LLC fills more address records than a typical LLC because state real estate commissions track the entity, the broker affiliation, and the tenant trust account on separate filings. This guide walks through which addresses a property management company actually needs, where state property management licensing boards require a broker license attached to the entity, and how a seven-city footprint fits a multi-state rental portfolio.
A holding company LLC owns the equity of one or more subsidiary LLCs rather than running its own operations. That structure creates more address records to manage, not fewer, because the parent LLC and each subsidiary each have their own state filings, EINs, bank accounts, and mail streams. This guide covers what a holding company LLC is, how a parent and subsidiaries are set up, and how a Delaware or Wyoming parent and multi-state subsidiaries align their addresses without inviting a veil-piercing argument.
A PO Box costs less, but it can't do what a virtual office can. Compare features, costs, and legal acceptance side by side to pick the right business address solution.
A real estate agent's commission LLC is a separate legal entity, and its address rules run through the state real estate commission, not only the Secretary of State. The brokerage affiliation, the license record, and the year-end commission documents each reference an address, and a mismatch between them is what stalls a commission deposit or a license renewal. This guide covers the three address slots a real estate agent LLC fills and where each one is checked.
Before a Series A data room goes to investors, a company's business address appears in at least four records that have to match: the Secretary of State filing, the Employer Identification Number letter, the bank's know-your-customer file, and the payment processor account. Investor counsel and equity tools like Carta surface the mismatches as diligence questions. This guide is a founder-side checklist for auditing the address before the data room is shared, not after a question comes back.
A state-licensed general contractor LLC has at least three address records that operate independently: the secretary of state LLC filing, the contractor license board, and the surety bond plus workers' compensation carrier. The formation guides cover the first one and stop. This guide covers the other two, including the parts where a virtual address can fill the slot and the parts where the license board still expects a physical site that a virtual address cannot replace.
