Compare your estimated tax liability under an all-cash sale versus spreading the gain over time using the IRS installment sale method (IRC §453).
| Year | Principal Received | Interest Received | Gain Recognized | Tax on Gain | Tax on Interest | Total Tax That Year |

Under the installment method, you only recognize capital gain proportional to the principal you actually receive each year. The IRS calculates this using your Gross Profit Percentage — the ratio of your total gain to the contract price. Interest payments are taxed separately as ordinary income each year.
Depreciation recapture (Section 1245/1250) is taxed in the year of sale at 25%, regardless of whether you use the installment method. These figures are excluded from the installment deferral calculation.
These are estimates only. State tax treatment of installment sales varies. Consult a CPA or tax attorney before making decisions based on these figures.
