Adjusted basis
Purchase price is only the starting point. Certain acquisition costs and capital improvements can increase basis; depreciation and other adjustments can reduce it.
Property-sale tax planning
Selling a home? Start by finding the facts that determine the gain.
Organize purchase records, improvements, occupancy, rental history and selling costs before closing—then request the actual basis and tax calculation as a defined piece of work.

What changes the answer
The sale price is only one line in the calculation.
Principal-residence exclusion
A qualifying seller may exclude up to $250,000 of gain—or up to $500,000 on certain joint returns. Ownership, use, filing status, prior exclusions and exceptions matter.
Rental or business use
Depreciation allowed or allowable, business use outside the living area, conversion dates and nonqualified-use periods can change what remains taxable.
Federal rate layers
Taxable gain can cross federal capital-gain brackets. Depreciation-related gain may face a different maximum rate, and the 3.8% NIIT depends on income and other facts.
California taxation
California generally taxes capital gains as ordinary income. The applicable marginal rate depends on the seller’s full California taxable-income picture.
Cash at closing
Mortgage payoff affects net cash received, but it generally does not reduce taxable gain. Cash proceeds and taxable gain are related—but different—questions.

Short answers
Common property-sale tax questions.
A useful estimate separates what is known from the assumptions that still need documentation.
Is tax based on the cash I receive after paying off the mortgage?
Generally no. The mortgage payoff affects cash received at closing. Gain generally starts with amount realized after selling costs minus adjusted tax basis.
Can home improvements reduce the gain?
Certain capital improvements may increase basis. Repairs and maintenance generally do not. Keep invoices, contracts, permits, settlement statements and records describing what the work changed.
Do I automatically get the $250,000 or $500,000 exclusion?
No. The maximum exclusion depends on ownership and use tests, filing status, prior use of the exclusion and special rules. Partial exclusions and disqualifying facts can also apply.
What if the home was rented or had a home office?
Depreciation allowed or allowable and the location and period of business or rental use can affect the exclusion and character of the gain. That history should be reviewed before relying on a simple estimate.
Does California have a lower capital-gain rate?
No separate lower California capital-gain rate generally applies. California taxes capital gains as ordinary income, so the seller’s broader income picture matters.
Can I hire Randall only for the sale analysis?
Yes, when the matter is a fit. Property-sale tax analysis can be separately scoped and does not require investment management or a comprehensive financial-planning engagement.
Before you sell
Turn the record outline into a documented calculation.
The scope can be limited to reconstructing basis, estimating gain and identifying the tax assumptions that still need resolution.
