Questions builders ask

Do I have to amend old returns?

Not for depreciation. Once two or more returns are filed, the depreciation you missed is taken all at once on this year's return. Energy credits are different: they go on an amended return, and only while that year is still open.

Why do the dates matter?

Each strategy has its own window. The home energy credit ended for homes sold or leased after June 30, 2026, and the energy-efficient building deduction for buildings started after that date. Older years close three years after the return was due.

What does my CPA get?

The study, the catch-up schedule and the form your CPA files with it, or the amended-return figures where that is the path, plus the asset detail for the depreciation software. Your CPA confirms every date.
