When is income taxable?

When is Income Taxable?

For Individual Income Taxpayers:

For individual taxpayers, income is considered taxable when it is received, regardless of whether it is cashed or immediately used. Even if payment is made directly to a third party on your behalf, it is still treated as your income.

Businesses Using the Cash Basis Method

Under the Cash Basis accounting method, two key rules apply:
  1. Income is reported and taxed in the year it is actually received.
  2. Expenses are reported and deducted in the year they are actually paid.
Example Scenario
  1. Fiscal Year End: December 31
  2. Transaction: ABC Company bills a client $1,200 on October 24, 2024, with payment due November 24, 2024.
  3. Payment: The client pays $1,260 (including a late fee) on January 22, 2025.
Tax Treatment: The payment is recorded in 2025, so the tax liability falls in the 2025 tax year, even though the services were performed and billed in 2024.

Businesses Using the Accrual Basis Method

Under the Accrual Basis accounting method, income and expenses are recognized when they are incurred, regardless of when cash is received or paid.
Example Scenario
  1. Fiscal Year End: December 31
  2. Transaction: ABC Company bills a client $1,200 on October 24, 2024, with payment due November 24, 2024.
  3. Payment: The client pays $1,260 (including a late fee) on January 22, 2025.
Tax Treatment: Because the service was performed and billed in 2024, the income is considered incurred in 2024. Therefore, the tax liability applies to the 2024 tax year, even though payment was not received until 2025.

Key Distinction

  1. Cash Basis: Taxes are based on when money changes hands.
  2. Accrual Basis: Taxes are based on when income and expenses are incurred, regardless of payment timing.
