Background & Context

2 stories

2.1

An EIN is not your state tax ID.

The federal EIN identifies the business to the IRS for payroll, federal tax filing, and bank-account opening. State tax IDs are separate, often required for state payroll, sales tax, and unemployment-insurance accounts. Some states issue multiple IDs for different functions. Using the EIN alone leaves state obligations unfiled.

Why It Matters

State agencies catch missing registrations through cross-checks with the federal EIN database, often years later, with penalties and interest accruing the whole time.

2.2

Why quarterly estimated payments fail in year two.

The federal safe harbor for estimated payments is the lesser of 90% of current-year tax or 100% (110% for higher incomes) of prior-year tax. New businesses meet safe harbor easily in year one when prior-year tax was zero. In year two, last-year-based safe harbor disappears and underpayment penalties surface.

Why It Matters

The penalty is not large per dollar but compounds across quarters and surprises owners who thought their bookkeeper was handling it. Cash flow gets squeezed at exactly the growth point where it is tightest.
