Consider an installment agreement
If you’re paying taxes via credit card because you can’t pay your tax bill all at once, consider an installment plan. This is an agreement with the IRS that lets you pay your tax debt in monthly payments. You can choose between a short-term plan that lasts 120 days, or a long-term plan that lasts more than 120 days. While you’ll still accrue interest on the balance, it’s typically less than the APR on most credit cards — so it may be a more prudent option in the long run.
To begin an installment plan, you must file your tax return and owe $50,000 or less in taxes, penalties and interest.
