Activity allocation · 100% enforced · Schedule E + Schedule C
One cost, one split
A cost that serves both the rentals and JCS cannot land whole on Schedule E. Enter it once, allocate it across activities, and the server holds the split to exactly 100% — so nothing is deducted twice and nothing is quietly abandoned.
Costs ·
Each cost, entered once, with its split across activities. Edit to re-allocate.
