Bit Co — operating as The BIT Company — is a tax-preparation and estate-planning firm at 8085 La Mesa Boulevard in La Mesa Village, steps from the La Mesa Village Farmers Market corridor and the Farmer's Table restaurant block. Mortgage-qualification packages assembled for home-purchase clients require two years of signed federal returns, W-2s, and self-employment income documentation — the same filing history that loan officers at firms like Jared Kelley - Home and Investment Planning Expert verify during the underwriting process. The firm's scope covers individual 1040 returns, trust and estate filings, small-business Schedule C and partnership returns, and complex multi-jurisdictional filings for military retirees who have changed state residency and sold rental properties in the same tax year. Renovation and addition projects financed through home-equity lines generate deductible-interest calculations and capital-improvement basis adjustments — tax-code intersections that arise when contractors such as HomeRevive Construction complete permitted work on residential properties. Estate-planning engagements model federal unified-credit utilization, portability elections under IRC Section 2010(c)(4), and California inheritance-tax exposure to structure asset transfers that minimize combined gift and estate tax liability across multi-generational family holdings.
