Can I change my IRS installment agreement payment amount?

Yes, you can request a modification to your installment agreement if your financial situation changes. Common reasons include: income reduction (job loss, reduced hours, retirement), increased necessary expenses (medical costs, child support changes), or desire to increase payments to pay off faster. To modify your agreement: (1) For online agreements, log into your IRS account at IRS.gov and modify the payment amount or date. (2) Call the IRS at 1-800-829-1040 and request a modification. (3) Submit a new Form 9465 with the revised terms. There is a $10 fee for online modifications. If you need to reduce your payment, the IRS may require updated financial information (Form 433-F or 433-A) to verify the need. If you want to increase your payment (to pay off faster or reduce total interest), you can do so at any time without restriction. You can also make additional lump-sum payments alongside your regular installment payments to reduce the balance faster. Any extra payments reduce the principal, which reduces future interest charges. Request the modification before missing a payment to avoid default.
