Trade value is not equity
Estimate the tax benefit.
Trade allowance versus net equity
The dealer's gross trade allowance can affect the taxable measure. Net equity is that allowance minus the old loan payoff. A $12,000 trade with an $8,000 payoff has $4,000 of equity, but the entered qualifying tax allowance is still $12,000.
Negative equity
When payoff exceeds trade value, the difference can be rolled into the new financing. That increases the amount funded even though the trade may still qualify under the selected state tax path.
Confirm eligibility
Like-kind, dealer participation, ownership, timing and documentation requirements can matter. Use this figure as a negotiation estimate and confirm the final taxable measure.
