How the IRS Installment Agreement Works

An IRS installment agreement breaks your federal tax debt into monthly payments. You apply, the IRS approves (or counters), and you make fixed monthly payments until the balance — plus interest and penalties — is paid off. The IRS offers three tiers.

Short-term plan (under $100,000): Up to 180 days to pay the full balance. No setup fee. Interest and the failure-to-pay penalty keep accruing, but there’s no cost to get on the plan. Good option if you have a lump sum coming — a bonus, a tax refund from another year, a real estate closing.

Long-term plan (under $50,000): Monthly payments for up to 72 months. Setup fee is $31 with direct debit or $130 if you pay manually. Apply through the IRS Online Payment Agreement tool — it takes about 15 minutes and approval is usually instant for straightforward cases.

Over $50,000: You’ll file Form 9465 along with a Collection Information Statement (Form 433-A or 433-F). The IRS reviews your entire financial picture — bank accounts, assets, monthly expenses — and determines what you can afford. Processing takes 30 to 90 days, and the IRS may propose a higher payment than what you requested.

The Cost of Waiting

Interest on IRS debt currently runs around 7% to 8% (federal short-term rate plus 3%). The failure-to-pay penalty adds 0.5% per month on the unpaid balance, dropping to 0.25% per month once you’re on an approved installment agreement.

On a $15,000 balance, that works out to roughly $1,050 to $1,200 in interest during the first year, plus $225 to $450 in penalties. By the time you finish a 5-year payment plan on a $15,000 debt, you’ll have paid closer to $20,000 total. The math gets worse the longer you stretch it.

Some Miami taxpayers put off applying because the paperwork feels complicated. It isn’t — for balances under $50,000, the online application is a web form. Every month you delay costs money in interest you could have avoided by starting payments sooner.

No State Tax Debt: Florida’s Advantage

This is the part New York and California taxpayers envy. When a Miami resident owes the IRS $20,000, that’s the full picture. An NYC taxpayer in the same situation probably owes another $6,000 to $10,000 to New York State, and an LA taxpayer owes a similar amount to the California FTB.

The practical benefit: one payment plan, one monthly payment, one creditor. You don’t have to coordinate two separate installment agreements with two agencies that don’t talk to each other. Your total monthly payment obligation is lower because there’s no state layer, and you avoid the risk of defaulting on a state plan if money gets tight.

The flipside: because Florida has no state income tax, some taxpayers underestimate their federal liability. They move from New York or California, stop having state taxes withheld, and assume their total tax bill dropped. It did — but if your federal withholding was calibrated for a high-tax-state situation, you might need to adjust your W-4 or your estimated payments to avoid owing the IRS at filing time.

What the IRS Can Do if You Don’t Pay

The IRS has serious collection tools, and Florida residency doesn’t shield you from any of them.

• Federal tax lien: Filed as a public record, attaches to all your property (including real estate in Miami-Dade), and shows up on title searches. The IRS generally files liens on balances over $10,000.
• Bank levy: The IRS can seize funds in your bank account after sending a final notice of intent to levy. You get 30 days to respond before they pull the money.
• Wage garnishment: The IRS can contact your employer directly and require them to send a portion of each paycheck to the IRS. The amount left for you is based on your filing status and number of dependents — it’s often less than you’d expect.
• Passport revocation: If you owe more than $62,000 (2025 threshold) and haven’t set up a payment plan, the IRS can certify your debt to the State Department, which can deny or revoke your passport. For Miami residents who travel internationally, this gets attention fast.

Alternatives to a Monthly Payment Plan

If the monthly payment the IRS requires doesn’t fit your budget, other options exist.

Offer in Compromise: You propose a lump-sum settlement for less than the full balance. The IRS accepted about 15,000 offers in the most recent fiscal year out of roughly 45,000 applications. Acceptance depends on your income, expenses, assets, and future earning potential. The process takes 12 to 24 months, and you’ll pay a $205 application fee plus an initial payment with your offer.

Currently Not Collectible (CNC): If your income barely covers basic living expenses, the IRS can place your account in CNC status. Collection activity stops — no levies, no garnishments — but interest and penalties keep accruing. The 10-year collection statute still runs, so if the IRS can’t collect within that window, the debt expires. This isn’t a forgiveness program, but it buys time if you’re in a genuinely difficult financial situation.

Partial-pay installment agreement: You make payments the IRS knows won’t cover the full debt before the collection statute expires. The remaining balance gets written off. This requires a full financial disclosure and is harder to get than a standard installment agreement, but it exists for taxpayers whose income supports some payment but not the full amount.

Getting Started in Miami

The IRS doesn’t care where you live — the application process is the same in Miami as it is in Manhattan or Montana. For balances under $50,000, go to IRS.gov, verify your identity through ID.me, and set up your plan online. Choose direct debit — the setup fee is lower and you won’t accidentally miss a payment.

For larger balances or complicated situations (multiple tax years, business tax debts, prior defaults), having a CPA or enrolled agent handle the application typically results in better terms. They know which expenses the IRS allows in the Collection Information Statement, how to present your financial picture accurately, and when to push back on the IRS’s proposed payment amount.
