Lok at this IRS webpage. there are multiple options and without knowing your personal situation it's impossible to say which is right for you
1) use IRS direct pay - for making full or partial payment without setting up a payment plan or offer in compromise
2) pau by debit or credit card - full or partial payment again without setting up a payment plan or offer in compromise
1) and 2) are not recommended if you ar not paying in full. penalties and interest charges for late payment are higher
3) a payment plan- you pay off over a period of time
4) offer in compromise - you get the IRS to agree to settle for less than the full amount owed
