Nearly a month past the filing deadline, the balance-due notices are landing in mailboxes. If yours says you owe more than you can pay, the worst response is silence. The IRS sells time on published terms, and the terms are more reasonable than most people fear, provided you pick the right plan and apply the cheap way.
There are two basic payment plans, plus a handful of fee levels that depend entirely on how you apply and how you pay. Here is the whole menu, compared, using the costs the IRS lists on its payment plans page as of this spring.
First, understand the meter that keeps running
No payment plan stops the clock; it only makes the clock cheaper. Interest accrues on any unpaid tax at the federal short-term rate plus 3 percentage points, adjusted quarterly. For the quarter that began April 1, 2026, that works out to 6 percent a year, down from 7 percent, per the IRS quarterly interest rate table.
On top of interest, the failure-to-pay penalty normally runs 0.5 percent of the unpaid tax per month, up to a lifetime cap of 25 percent. Getting an installment agreement approved cuts that rate in half, to 0.25 percent per month, which is one of the quieter arguments for formalizing a plan instead of just sending money when you can.
The short-term plan: 180 days, no setup fee
If you can clear the balance within about six months, this is the obvious choice. Individuals who owe less than $100,000 in combined tax, penalties, and interest can get up to 180 extra days to pay in full, with no setup fee at all, whether you apply online, by phone, or by mail. Interest and the failure-to-pay penalty continue during the window, but there is no charge for the arrangement itself.
You can apply in minutes through the IRS online payment agreement tool or your IRS online account. Note that only individuals can set up a short-term plan online; businesses need to call.
The long-term plan: monthly payments, fees from $22 to $178
If six months is not realistic, the long-term installment agreement spreads the balance over monthly payments. Individuals qualify to apply online if they owe $50,000 or less in combined tax, penalties, and interest and have filed all required returns. The setup fee varies fourfold depending on two choices:
How you pay. Direct debit, where the IRS pulls the payment from your checking account automatically, costs $22 to set up online. Choosing to send payments yourself, by check or electronically each month, raises the online setup fee to $69, and direct debit is required anyway once you owe between $25,000 and $50,000.
How you apply. The same plans cost dramatically more through a human: $107 for direct debit and $178 for non-direct debit when set up by phone, mail, or in person. The paper route, Form 9465, exists for people who cannot use the online tool, but it is the most expensive door into the same room.
Low-income taxpayers, defined as those with adjusted gross income at or below 250 percent of the federal poverty level, get the fee waived entirely with direct debit, or reduced to $43 (and potentially reimbursed) without it. The IRS has also rolled out streamlined Simple payment plans that make qualifying more straightforward for most individual balances.
What a plan actually costs: a worked example
Take a $5,000 balance paid off over 12 months on a direct-debit plan set up online. You would pay the $22 fee, interest at 6 percent on the declining balance, roughly $160 over the year, and the reduced failure-to-pay penalty of 0.25 percent per month on what remains unpaid, roughly $80 more. Call it about $260 in total carrying cost, in the neighborhood of 5 percent of the debt. Unpleasant, but far cheaper than most credit cards, and it ends the notice cycle.
These figures are estimates for illustration; your exact interest depends on your payment dates, and rates reset quarterly.
The fine print that keeps plans alive
Once a plan is in place, the IRS generally will not levy your wages or accounts while it is active, or while your application is pending. In exchange, you must stay current: make every monthly payment, file every future return on time, and pay new balances in full, or the agreement can default (reinstatement carries its own fee, though changing payment amounts or dates online costs $10). Expect any future refunds to be applied against the balance until it is gone; that is standard and does not replace your monthly payment.
If even a monthly payment is out of reach
The payment plans assume the debt is payable over time. If it truly is not, different tools exist: the IRS can mark an account currently not collectible or consider an offer in compromise, which settles for less than the full amount in limited hardship cases. Both have real eligibility tests, and both are exactly where the late-night “pennies on the dollar” ads overpromise. Start at the IRS pages linked above, not with a firm that charges thousands to fill out the same free forms.
For most people who owe, the playbook is short: file on time even when you cannot pay, apply online, choose direct debit, and let the cheapest version of the plan do its work.
