State-Specific Deadlines
State deadlines vary. Some states conform to federal deadlines, others have different dates. Alan handles multi-state filings and ensures compliance across all jurisdictions where you have nexus.
Extension Strategies
If you can't meet a deadline, extensions are available — but they extend time to file, not time to pay. Estimated taxes must still be paid by the original deadline to avoid penalties.
Next Steps
Missing a deadline means penalties and interest. Alan provides quarterly reminders, handles all filings, and ensures you never miss a deadline. If you're behind, he can negotiate penalty abatements and get you current.
