Many taxpayers can’t pay their tax bill in full when it’s due. Unexpected income, penalties, or cash-flow challenges can make a lump-sum payment unrealistic. Instead of falling behind, the IRS allows individuals and businesses to set up payment plans that spread the balance into manageable monthly payments. 

If you owe taxes, you can call the IRS to discuss your options and request an installment agreement. Knowing the right phone number, what to expect during the call, and how the process works can help you act quickly, avoid penalties, and take control of your tax debt. 

IRS Phone Number for Payment Plans 

If you want to set up a payment plan by phone, you need to contact the IRS directly. The IRS uses specific phone lines for tax balances and installment agreements, so calling the right number helps you reach the correct department faster. 

For individual taxpayers, the main IRS phone number for payment plans is 800-829-1040. This line connects you with IRS representatives who handle tax balances, payment options, and installment agreements. The IRS typically answers calls Monday through Friday during standard business hours, although wait times can vary depending on the time of year. 

Businesses that owe taxes may need to call a different number. The IRS Business & Specialty Tax Line at 800-829-4933 handles questions related to business taxes, employer tax liabilities, and business payment plans. Calling this line allows business owners to discuss their outstanding balances and explore available payment options. 

Before you call, it helps to prepare key information, such as your Social Security number or Employer Identification Number (EIN), the tax years you owe, and the total balance due. Having this information ready can make the conversation more efficient and help the IRS representative propose a payment plan that fits your situation. 

How IRS Payment Plans Work 

An IRS payment plan, also called an installment agreement, allows you to pay your tax balance over time instead of in one lump sum. Once the IRS approves your request, you make fixed monthly payments until you pay off your balance, including interest and fees. 

The process usually starts when you contact the IRS or apply online. The IRS reviews your tax balance, financial situation, and payment history. Based on this information, the agency determines whether you qualify for a payment plan and what type of plan fits your situation. 

In many cases, you can propose a monthly payment amount. The IRS often approves reasonable payment terms as long as they align with your income and expenses. For smaller tax balances, the IRS may approve streamlined plans with minimal documentation. For larger balances, the IRS may require detailed financial information before approving a plan. 

Once you set up a payment plan, you must make payments on time and stay current on future tax filings. Missing payments or failing to file future returns can cause the IRS to cancel your agreement and restart collection actions. However, if you follow the terms of your plan, you can avoid more aggressive enforcement measures while steadily reducing your tax debt. 

What to Prepare Before You Call the IRS 

Before you call the IRS about a payment plan, gather the key information you’ll need during the conversation. Preparing ahead of time helps you move through the call faster and increases your chances of securing a payment plan that fits your budget. 

Start with your identification details. Have your Social Security number ready if you file as an individual, or your Employer Identification Number (EIN) if you own a business. You should also know which tax years you owe and the total balance due, including penalties and interest. 

Next, review your financial situation. Estimate your monthly income, essential expenses, and how much you can realistically pay each month. The IRS may ask questions about your finances, especially if you owe a larger amount or request a lower monthly payment. 

If you plan to set up automatic payments, keep your bank account information nearby. Direct debit payments often make the process easier and can reduce certain fees. With these details prepared, you can speak confidently with the IRS and avoid delays when requesting a payment plan. 

Other Ways to Set Up an IRS Payment Plan 

Calling the IRS is not the only way to set up a payment plan. In many cases, you can apply online or submit a request by mail. Choosing the right method depends on your tax balance, financial situation, and how quickly you want to finalize your agreement. 

The fastest option is the IRS Online Payment Agreement system. Through the IRS website, you can request a short-term or long-term payment plan, select a monthly payment amount, and receive approval in many cases without speaking to an agent. This option works best for individuals with straightforward tax situations and smaller balances. 

You can also apply for a payment plan by mail using IRS Form 9465, Installment Agreement Request. This method may take longer, but it can work well if you prefer written communication or need to provide additional documentation. 

Despite these alternatives, calling the IRS can still be helpful in certain situations. If you owe a larger amount, need flexible payment terms, or want to negotiate your monthly payment, speaking with an IRS representative can provide clarity and personalized options. Many taxpayers find that a direct conversation helps them understand their obligations and choose the most practical path forward. 

Types of IRS Payment Plans 

The IRS offers several types of payment plans to match different financial situations. Understanding these options helps you choose the plan that fits your tax balance and budget. 


A short-term payment plan gives you up to 180 days to pay your tax balance in full. This option works well if you expect to pay off your taxes within a few months and want to avoid setting up a long-term agreement. 


A long-term installment agreement allows you to spread your payments over several years. Most taxpayers use this option when they owe a larger balance and need predictable monthly payments. The IRS typically approves these plans if you file all required returns and propose a reasonable payment amount. 


Some taxpayers qualify for a streamlined installment agreement. This option requires less documentation and offers faster approval, especially for balances below certain thresholds. The IRS uses this approach to simplify the process for many individuals and small businesses. 

In certain cases, the IRS may approve a partial payment installment agreement. With this plan, you pay less than the full tax balance over time, based on your financial capacity. The IRS evaluates your income, expenses, and assets before approving this type of agreement. 

Businesses can also set up payment plans for payroll taxes, corporate taxes, or other business liabilities. These plans often require additional financial information, but they follow the same core principle: structured monthly payments that help businesses stay compliant while managing cash flow. 

Fees and Interest for IRS Payment Plans 

The IRS charges fees and interest when you set up a payment plan. Understanding these costs helps you estimate the true price of paying your tax balance over time. 

First, the IRS charges a setup fee for most installment agreements. The fee varies depending on how you apply and how you make payments. Online applications and direct debit payments usually cost less than agreements set up by phone or mail. Low-income taxpayers may qualify for reduced fees. 


Second, the IRS continues to charge interest on your unpaid tax balance until you pay it in full. The interest rate changes quarterly and applies to both the original tax amount and any penalties. Even with a payment plan, your balance can grow if your monthly payments remain too low. 

The IRS also applies penalties for late payment. While a payment plan reduces the risk of aggressive collection actions, it does not eliminate penalties entirely. However, setting up an installment agreement typically lowers the failure-to-pay penalty compared to doing nothing. 


To reduce overall costs, many taxpayers choose higher monthly payments or automatic withdrawals. Paying off your balance faster minimizes interest and penalties, while direct debit payments help you avoid missed payments and additional fees. 

Key Takeaways 

Setting up an IRS payment plan can make an overwhelming tax bill feel manageable. Instead of paying your balance in one lump sum, you can spread payments over time and regain control of your finances. Knowing the correct IRS phone number, understanding how installment agreements work, and preparing the right information before you call can simplify the process and reduce unnecessary stress. 

Whether you choose to call the IRS, apply online, or submit a request by mail, taking action early is critical. Payment plans help you avoid escalating penalties and more serious collection measures while giving you a clear path to resolving your tax debt. By understanding your options and choosing a plan that fits your budget, you can move forward with confidence and stay on track with your tax obligations.
