Bank accounts, state registrations, changes, and closing an EIN.

Business Bank Account Requirements: What You Need
What banks generally ask for when you open a business account, by business type.
Do You Need an EIN to Open a Business Bank Account?
For an LLC, corporation, partnership, estate or trust, the bank will ask for one. For a sole proprietor it depends on the bank. What each account type needs, and what else to bring.
How to Get a State Tax ID Number for Your Business
There is no single state tax ID. Which accounts your business needs, the steps to register, and each state's sales tax permit name and agency.
State Employer ID Numbers: All 50 States in One Table
The withholding account each state issues after the federal EIN, what the agency calls it, where to register, and who runs unemployment insurance. Plus the states with no wage income tax, and the ones that file withholding under the EIN itself.
Sales Tax Permit: Who Needs One and How to Get It
Who needs a sales tax permit, how to apply with your state, and how it differs from a resale certificate and an EIN.
LLC to S Corp: How to Make the Switch
An LLC can be taxed as an S corporation by filing Form 2553. Who qualifies, the deadline, and what changes.
Do I Need a New EIN? The Full Scenario Table
A new EIN is needed when the taxpayer changes, not when its details do. Name changes, new partners, and S-corp elections keep it; incorporating, sole prop to partnership, and a trust turning irrevocable need a new one.
Can a Business Have Multiple EINs? One Entity, One Number
One entity gets one EIN, but one owner can have several. How many each setup needs, why a sole proprietor shares one, and what to do with an extra number.
Changing Your EIN's Business Name, Address, or Responsible Party
An EIN is permanent, but the record behind it can be updated. Which changes are a letter, which are Form 8822-B, and which changes actually require a brand new EIN.
Does an EIN Expire?
The IRS calls an EIN permanent, and there is nothing to renew. What happens when a business closes, restarts or goes quiet for years, and when you do need a new number.
How to Cancel or Close an EIN
An EIN is never reused or deleted, but the IRS will close the business account tied to it. When that is worth doing, what to write in the letter, and why a wrong EIN is a different fix.
