Form 1120 Page 1 Line 18 interest adjustment
An unexpected adjustment may appear on Form 1120 Page 1 Line 18 when Form 8990 generates and transfers the business interest deduction amount. Suppress the auto-calculation to resolve this.
When Form 8990 generates, the amount on Form 8990 Page 2 Line 30 transfers to Form 1120 Page 1 Line 18 instead of consolidating interest deduction amounts directly. This can cause an unexpected adjustment to appear on Line 18.
To remove or control this adjustment:
- Go to .
- In theOptionssection, selectSuppress auto calculation.
- Run a full recompute.
The adjustment no longer appears on Line 18, and the interest amount now transfers correctly.
note
When you suppress auto-calculation, Line 30 won't calculate automatically. If you need a specific amount on Line 30:
- In the sameAdjustmentssection, enter the amount onLine 30 Current year business interest deduction.
- Run a full recompute.
