Quarterly Tax Payment
Quarterly estimated tax payments are required if you expect to owe $1,000+ in taxes and don"t have sufficient withholding (self-employed, freelancers, investors).
Taxable Income = Expected Annual Income - Deductions
Estimated Annual Tax = Taxable Income × Effective Tax Rate
Quarterly Payment = Estimated Annual Tax / 4
