Definition
Cash Flow After Taxes (CFAT) is the cash remaining to an investor after paying operating expenses, debt service, and income taxes.
CFAT reflects the true spendable cash from an investment after tax obligations.
Core Formula
CFAT is typically calculated as:
CFAT = Pre-Tax Cash Flow − Taxes Paid
Or expanded:
CFAT = (NOI − Debt Service − Reserves) − Income Taxes
Why Taxes Often Don’t Equal Cash Flow × Tax Rate
Real estate taxation is heavily influenced by non-cash deductions such as depreciation and interest expense.
- Depreciation reduces taxable income without reducing actual cash.
- Interest is tax-deductible, but principal payments are not.
- Tax losses may offset other passive income (subject to passive activity loss rules).
As a result, a property can produce positive cash flow but minimal taxable income — increasing CFAT relative to pre-tax projections.
Example
Assume:
- NOI: $500,000
- Debt Service: $340,000
- Replacement Reserves: $25,000
Pre-Tax Cash Flow = $135,000
If taxable income after depreciation is only $40,000 and the investor’s effective tax rate is 25%:
Taxes owed = $10,000
CFAT = $135,000 − $10,000 = $125,000
Why CFAT Matters
- True investor return: Shows real after-tax benefit.
- Comparing investments: Tax-advantaged assets may outperform on CFAT basis.
- Distribution planning: Determines actual take-home cash.
- Long-term modeling: Important for IRR and exit projections.
CFAT vs Related Metrics
- Cash Flow Before Taxes (CFBT): Excludes tax impact.
- NOI: Excludes both debt and taxes.
- Levered IRR: Often calculated using after-tax cash flows.
- Return of Capital: A distribution that may not be taxable income.
Advanced Considerations
- Sale taxes and depreciation recapture impact final-year CFAT.
- Cost segregation can accelerate depreciation and increase early CFAT.
- Real estate professional status may allow active loss treatment.
- Entity structure (LLC, partnership, REIT) influences tax flow-through treatment.
Common Pitfalls
- Ignoring state income taxes.
- Assuming tax rate remains constant across years.
- Forgetting capital gains tax on sale.
- Confusing accounting income with taxable income.
Investor Checklist
- Model depreciation correctly.
- Understand passive loss limitations.
- Forecast sale-year tax impact.
- Consult a qualified tax advisor before making projections.
