When a partner's basis history is missing, most workflows quietly assume zero. k1flow flags the gap instead of guessing, and shows every step in an Excel workpaper you can tick and tie. Missing years? Book a basis rescue and we rebuild them with you.
A partner with an unrecorded history and a loss this year. Here is what happens when the missing years are assumed to be zero, and what happens when they're rebuilt.
Nothing warns you. The return just looks normal.
| Basis at start of year | 0 |
| This year's income and contributions | 12,000 |
| This year's loss | (40,000) |
| Loss suspended for lack of basis | (28,000) |
| Loss allowed on the return | 12,000 |
Prior K-1s are rolled forward and every number is traceable.
| Basis rebuilt from prior years | 46,500 |
| This year's income and contributions | 12,000 |
| This year's loss | (40,000) |
| Loss suspended for lack of basis | 0 |
| Loss allowed on the return | 40,000 |
The tax math is fixed code, so the same inputs always give the same numbers.
If last year's basis or at-risk amount is missing, k1flow says so plainly instead of filling in zero.
For the years nobody tracked, we rebuild the capital account and outside basis with you, year by year, using the same engine.
When something doesn't reconcile, the workpaper and tax software codes stay blocked until it's resolved.
Four steps, with you reviewing at each one.
The demo is for synthetic K-1s only. Leave the starting basis blank and watch the gap get flagged.
