If your modified adjusted gross income (MAGI) is $100,000 or less ($50,000 or less if married filing separately), you can deduct your loss up to the amount specified above. If your MAGI is more than $100,000 (more than $50,000 if married filing separately), your special allowance is limited to 50% of the difference between $150,000 ($75,000 if married filing separately) and your MAGI. Generally, if your MAGI is $150,000 or more ($75,000 or more if you are married filing separately), there is no special allowance.
