For people who paid AMT on an ISO exercise
How fast does your AMT credit come back?
AMT paid on an ISO exercise becomes a credit. Each year you can use only part of it. See the schedule for your numbers.
This is live. Change any number; it recomputes in your browser and nothing you type leaves it.
About $9,730 of the $50,000 credit comes back in 2026.
All of it is back by 2031.
| Year | Comes back | Still waiting |
|---|---|---|
| 2026 | $9,730 | $40,270 |
| 2027 | $9,730 | $30,540 |
| 2028 | $9,730 | $20,810 |
| 2029 | $9,730 | $11,080 |
| 2030 | $9,730 | $1,350 |
| 2031 | $1,350 | $0 |
What this assumes
- Assumes flat W-2 income of $250,000 for every projected year.
- Assumes no new AMT preference items (no further ISO exercises) during the horizon.
- Years after 2026 use 2026 tax tables.
- Selling the ISO shares can bring the credit back sooner. That is not counted here.
The app counts your sales, vests and withholding too, which change how much credit you can use.
