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.
Form SS-4 asks for more than one address, and getting them wrong, or using a registered agent address, can cause problems later. Here is what the IRS asks for on each line, what to do with a virtual address, and the registered agent question that trips people up.
Forming an LLC for your Airbnb or VRBO rental raises a question most host guides skip: which address goes on the LLC, on the registered agent line, and on the local rental permit. Here is how the three address layers work and where they differ by state.
Renaming an LLC means filing articles of amendment with the state, then telling the IRS so its records match, usually without a new EIN. Here is how the name change works, how it differs from a DBA or an address change, and everyone you need to update.
Closing an LLC is a sequence of steps, not a single form. You wind up the business, file articles of dissolution with the state, file final tax returns, and separately close the EIN. Here is the order, why your address still matters after you close, and where things go wrong.

A US LLC counts as a US person for FBAR, so foreign accounts that together top $10,000 at any point in the year usually have to be reported on FinCEN Form 114. Here is who must file, how the combined threshold works, the deadline, and the penalties for getting it wrong.
A Delaware LLC pays a flat $300 franchise tax every year, due June 1, no matter how much it earned or whether it did business at all. Here is what the tax is, how it differs from the corporation rules, the late penalty, and where your registered agent and address fit.
When you move and your LLC needs to move with you, there are three real options: domesticate it into the new state, register it as a foreign LLC, or dissolve and start fresh. Here is how each works, which one keeps your EIN, and where your address fits.
Form 8832 is the check-the-box election that lets an LLC override its default tax classification, usually to be taxed as a C corporation. Here is how it differs from Form 2553, the 60-month lock-in, the 75-day timing rule, and what it means for foreign-owned LLCs.
Once your LLC pays its first W-2 employee, it usually has to file Form 941, the employer's quarterly federal payroll tax return. Here is who files, the single-member LLC nuance, the four deadlines, why depositing is not the same as filing, and the zero-wage quarter rule.
A foreign-owned single-member LLC treated as a disregarded entity has to file Form 5472 attached to a pro forma Form 1120 whenever it has a reportable transaction with a related party. Here is who must file, how the mail-or-fax process works, why the penalty is $25,000, and where your US address fits in.
What address a 501(c)(3) nonprofit actually needs: a registered agent street address in its state, a mailing address for the IRS determination letter, and extra addresses when you fundraise across state lines.
Most Texas LLCs must file a franchise tax report each year, but if your revenue is below the current no-tax-due threshold, the tax owed is zero. You still have to file the report and the Public Information Report by May 15. Here is how the margin tax, the threshold, and the address on your PIR fit together for multi-state founders.
