6 steps to calculate your different minimal tax (AMT)
Step 1
Determine your common tax legal responsibility, which you will discover in your tax return or on Line 16 in your Type 1040. Don’t make the error of utilizing the quantity paid or refunded on the final line of your tax return.
Your common tax legal responsibility is the tax stability earlier than any offsetting withholding or funds are utilized.
Duncan’s common tax legal responsibility is $100,000.
Step 2
Now, it’s time to calculate your ISO AMT adjustment.
When you exercised and held any ISOs, begin by calculating your discount factor.
To take action, you’ll want the next numbers:
- The honest market worth of the inventory on the date you exercised. For Duncan, it’s $55.
- The strike value (i.e. value paid) per ISO. For Duncan, it’s $12.
The distinction between these two numbers is your discount factor. Duncan’s discount factor is $43 per share.
Additionally work out the variety of shares you exercised and held. For Duncan, that quantity is 10,000 shares.
Subsequent, plug the above numbers into this equation:
ISO AMT adjustment = discount factor * variety of shares
$43 * 10,000 = $430,000
Duncan’s ISO AMT adjustment is $430,000.
Step 3
Determine your AMT taxable revenue by including your common tax legal responsibility and ISO AMT adjustment collectively.
Common tax legal responsibility + ISO train = AMT taxable revenue
Right here’s what that equation would seem like for Duncan:
$100,000 + $430,000 = $530,000
His AMT taxable revenue is $530,000.
Step 4
Alter your AMT taxable revenue based mostly in your submitting standing — are you single or married?
If single, scale back the quantity from Step 3 by $85,700.
For a single Duncan, that might be: $530,000 – $85,700 = $444,300.
If married, scale back the quantity from Step 3 by $133,300.
For a married Duncan, that might be: $530,000 – $133,300 = $396,700.
Observe: This quantity can have a prorated discount in case your AMT taxable revenue exceeds a sure greenback quantity.
Step 5a
Subsequent, calculate your different minimal tax.
Multiply the quantity you calculated in Step 4 by 28%. If the quantity you calculated in Step 4 is decrease than $220,700, multiply it by 26% as a substitute, and skip step 5b beneath.
As a result of Duncan’s Step 4 calculation is larger than $220,700, he’ll multiply it by 28%.
For a single Duncan, the calculation would seem like:: $444,300 * 0.28 = $124,404.
For a married Duncan, the calculation would seem like: $396,700 * 0.28 = $111,076.
Step 5b
If Step 5b applies to you (that’s, if the quantity you calculated in Step 4 was decrease than $220,700), it’s good to make yet one more adjustment to calculate your different minimal tax:
Cut back the quantity you calculated in Step 5a by $4,414.
For a single Duncan, the calculation could be: $124,404 – $4,414 = $119,990.
For a married Duncan, the calculation could be: $111,076 – $4,414 = $106,662.
Step 6
The final step to calculate your anticipated AMT is decreasing the AMT you calculated in Step 5 by common tax.
Cut back your calculation from Step 5a (or 5b, if relevant) by your common tax legal responsibility, which is the quantity you calculated in Step 1.
For a single Duncan, the calculation could be: $119,990 – $100,000 = $19,990.
For a married Duncan, the calculation could be: $106,662 – $100,000 = $6,662.
If single, Duncan’s anticipated different minimal tax is $19,990.
If married, Duncan’s anticipated different minimal tax is $6,662.
