This deadline guide for the 2024 tax year lists key dates for various tax-related forms, payments, returns, extensions and IRS interactions.

Why are these deadlines so important? 

  • Penalties & Interest: If you miss a tax deadline, the government may charge you penalties and interest. These penalties are in place to encourage timeliness and by meeting the deadlines, you can avoid unnecessary financial loss. 
  • Maintain Good Standing with Tax Authorities: Timely filing and payment of taxes helps maintain a positive relationship with tax authorities. This can be important for future interactions, audits and overall compliance with tax laws. 
  • Budgeting & Financial Planning: Knowing the deadlines for tax filings can help you plan your finances accordingly and budget for tax liabilities. 
  • Credit & Financial Standing: For businesses, meeting tax deadlines can impact your credit and financial standing. Lenders and investors may review a company’s tax compliance as part of their decision-making process.
