How to calculate the Capital Gain Adjustment amount on Form 1040


🔍 How to calculate the Capital Gain Adjustment amount on Form 1040

The capital gains adjustment is based on a formula in the IRS instructions for Form 1116.

Instruction for Form 1116, page 8

⚠️ Before You Begin

To make the capital gains adjustment, you will need to know:

  • Your foreign source qualified dividends or capital gain distributions in each separate category
  • The tax rate that applies to each category (0%, 15%, or 20%)

📊 Step-by-Step Guide

Step 1: Identify the category and applicable tax rate

Use this when you need to determine which multiplier to use for each separate category.

To adjust your foreign source qualified dividends or capital gain distributions, you will work in each separate category.

Step 2: Multiply by the correct adjustment factor

Use this when you need to calculate the adjustment amount for each category.

Multiply your foreign source qualified dividends or capital gain distributions in each separate category by:

  • 0.4054 if the foreign source qualified dividends or capital gain distributions are taxed at a 15% rate
  • 0.5405 if they are taxed at a 20% rate

Step 3: Enter the results on the correct line

Use this when you need to report the calculated adjustment on Form 1116.

Include the results on line 1a of the applicable Form 1116.

Step 4: Handle the 0% rate category

Use this when you need to apply the rule for categories taxed at 0%.

You adjust your foreign source qualified dividends or capital gain distributions taxed at the 0% rate by not including them on line 1a.
