The destination‑based cash flow tax (DBCFT) is a proposal to replace the U.S. corporate income tax with a system that taxes cash outflows rather than profits and bases tax liability on where goods and services are consumed. It combines three core changes:
- Immediate expensing – businesses can deduct the full cost of investment in equipment and research in the year incurred, eliminating depreciation schedules.
- Elimination of interest treatment – the deduction for interest paid is removed and interest received is no longer taxed.
- Border adjustment – imports are denied a deduction while exports are excluded from taxable income, making the tax “destination‑based.”
The plan also integrates the business tax with the individual income tax by repealing the Section 199A deduction and applying a flat 21 % rate to pass‑through entities, subject to the same border adjustment.
Economic impact
- The Tax Foundation’s general‑equilibrium model projects a 1.4 % increase in long‑run GDP.
- On a dynamic basis, the reform would reduce the 10‑year federal deficit by about $3.9 trillion, including interest savings.
These gains stem largely from the removal of depreciation drag, the reduction of the debt‑bias, and the curtailment of profit‑shifting incentives.
How the cash‑flow base addresses current distortions
- Inflation erosion – Under the current code, deductions lose real value over time; immediate expensing preserves the full real cost of investment.
- Debt‑equity bias – Presently, interest payments are deductible while dividend payments are not, making debt artificially cheaper. Removing the interest deduction narrows this bias, aligning the cost of debt with equity financing.
The bulk of the projected growth effect comes from the ability of firms to expense investments immediately.
How destination‑based taxation curtails profit shifting
- Multinational firms currently shift profits to low‑tax jurisdictions (e.g., licensing patents to a Bermuda subsidiary).
- By taxing only the portion of income linked to goods and services consumed in the U.S., the border adjustment eliminates many of the mechanisms that enable such shifting.
- The approach mirrors the trade‑neutrality of value‑added taxes (VATs), which levy taxes on imports at the border and refund taxes on exports, resulting in no long‑run effect on trade volumes according to IMF evidence.
Treatment of non‑corporate (pass‑through) businesses
If the DBCFT applied only to corporations, pass‑through entities would retain the origin‑based individual income tax, creating arbitrage opportunities. The proposal therefore:
- Extends the border adjustment to all business forms.
- Repeals the Section 199A deduction.
- Subjects pass‑throughs to the same 21 % flat, border‑adjusted rate as corporations.
This uniformity avoids incentives for firms to restructure solely to exploit tax differentials.
Distributional effects
- A border‑adjusted corporate tax alone is modestly progressive because it taxes consumption funded by wealth, rents, and market power—income streams more prevalent among higher‑income households.
- When combined with the flat 21 % rate on pass‑through income, the overall reform becomes regressive:
- Bottom quintile after‑tax income falls 5.4 %.
- Top 0.1 % after‑tax income rises 2.9 %.
These estimates are dynamic and incorporate both direct tax changes and indirect economic effects.
Implementation challenges
| Issue | Key considerations |
|---|---|
| Symmetry | The tax must treat gains and losses equally; otherwise investment incentives remain distorted. Loss carrybacks/forwards with interest accrual are proposed to preserve neutrality. |
| Currency adjustment | The expected appreciation of the dollar (to offset higher import costs) could affect debt‑service costs for dollar‑denominated liabilities. A phased rollout may mitigate market disruption. |
| Financial sector | Measuring the tax base for financial intermediation is difficult, so a separate regime for banks and insurers is typically required. |
| World Trade Organization (WTO) rules | Because a DBCFT exempts exports, it could be viewed as a prohibited subsidy. Pairing the DBCFT with a VAT and an employer‑side payroll tax could replicate the economic effect while staying within WTO constraints. |
| Administrative complexity | Implementing loss carrybacks/forwards, tracking border adjustments across all entity types, and coordinating with existing payroll and VAT systems would demand extensive rulemaking and compliance infrastructure. |
Policy considerations
A DBCFT simultaneously lowers the tax penalty on investment, reduces the bias toward debt financing, and limits profit‑shifting incentives, while generating substantial revenue and boosting long‑run output. However, the reform’s regressive distributional impact (when applied to pass‑throughs) and the significant design complexities—particularly around symmetry, currency effects, financial sector treatment, and WTO compliance—must be addressed before implementation.
