Ask The Taxgirl: SMLLC & Estimated Payments

Taxpayer asks:

I started a single member LLC this year, and need to make estimated tax payments.

When I went onto the IRS site to make payments, it asked for either my EIN or my SSN for the payments.

Am I making payments on both?

Taxgirl says:

You’re only making payments for the LLC once.

The big question is whether you are operating as a disregarded entity. If you are (and most single-member LLCs do), then you don’t need the EIN – just use your SSN. You’ll report your tax info directly on your form 1040 since there’s no separate return for a Single Member LLC treated as a disregarded entity for tax purposes. So, when calculating estimated payments, file your estimated taxes using a form 1040-ES.
