Question 1

What's the most important tax deadline for New York LLCs?

Accepted Answer

For most New York LLC owners: federal quarterly estimated tax payments (April 15, June 15, Sept 15, Jan 15) + New York annual report (Biennial, anniversary) + federal tax return (March 15 for partnerships/S-Corps, April 15 for SMLLC). Missing the annual report triggers admin dissolution.

Question 2

When are estimated tax payments due for New York LLCs?

Accepted Answer

Federal: quarterly on April 15, June 15, Sept 15, and Jan 15 of the following year. Pay at least 100% of last year's total tax (110% if AGI > $150K) or 90% of current year's liability to avoid underpayment penalties. New York state estimated tax varies — check New York Department of Revenue for state-specific quarterly dates.

Question 3

What's the New York state annual report deadline?

Accepted Answer

Biennial, anniversary. Missing this deadline risks administrative dissolution of your LLC — which retroactively removes liability protection. Calendar it immediately after formation.

Question 4

When are federal LLC tax returns due?

Accepted Answer

Single-member LLC (disregarded): April 15 with personal 1040. Multi-member LLC (partnership): Form 1065 due March 15. S-Corp LLC: Form 1120-S due March 15. C-Corp LLC: Form 1120 due April 15. All except SMLLC can extend 6 months (to Sept 15 or Oct 15).

Question 5

What are the penalties for missing deadlines in New York?

Accepted Answer

Federal: 5%/month late filing (up to 25% of tax). State: varies — CA franchise fail = $800 + interest; FL late annual = $400; NY annual late = $9 penalty; TX franchise late = $50+. Admin dissolution risk if annual compliance missed 1-3 years.

Question 6

Does New York offer tax extensions?

Accepted Answer

Federal: automatic 6-month extension via Form 4868 (individual) or Form 7004 (entity). New York state extensions often require separate filing — most states grant 6 months but require a state extension form. Extensions extend filing time, NOT payment time — penalty interest still accrues on unpaid tax.
