State Tax Debt
Connecticut Back Taxes: What to Do in 2025
The short answer: Connecticut back taxes can be owed to the IRS, the Connecticut Department of Revenue Services (DRS), or both. Each agency has its own rules. The fastest way to stop interest and enforcement is to file any missing returns, confirm what you owe to each, and set up a payment plan or relief option before collection starts.
⏱ Why timing matters: interest keeps adding to a Connecticut back tax balance every single month, with both the IRS and DRS. Acting early — before a state tax warrant or an IRS levy notice — is the difference between choosing your own payment plan and having the agency choose collection for you.
First, figure out who you owe
The phrase "Connecticut back taxes" covers two very different debts, and people mix them up all the time.
Federal taxes — income tax on your federal return — are owed to the IRS. State taxes — Connecticut income tax, sales tax, business taxes — are owed to the Connecticut Department of Revenue Services, usually just called DRS. They are separate agencies. A payment plan with the IRS does nothing for your state balance, and a deal with DRS does nothing for your federal one.
So step one is simple: find out exactly what you owe to each. For the IRS, check your IRS online account. For the state, log in or create an account at the Connecticut Department of Revenue Services through its myconneCT portal. Until you see real numbers from both, you're guessing.
Why you owe Connecticut back taxes
Most state back tax balances come from one of a few things: you filed a Connecticut return but couldn't pay the full amount, you didn't file at all for one or more years, you moved and missed a part-year filing, or self-employment income left you short. Sales tax debt is common for small business owners who collected the tax but fell behind sending it in.
If unfiled returns are part of your problem, that's worth fixing first — you generally can't settle a balance the agency can't even calculate yet. Our guide on how many years of back taxes you have to file walks through the federal lookback, and the same idea applies to the state: file the returns, then deal with the balance.
What happens if you ignore Connecticut back taxes
Both agencies escalate, just on different tracks. With DRS, ignoring a state balance can lead to:
- Billing notices — the state's first requests for payment, with interest already attached.
- Tax warrant — a legal document that lets the state enforce the debt, similar to a court judgment.
- State tax lien — a claim against your property that can show up when you sell or refinance a home.
- Bank execution and wage execution — the state can pull money from your bank account or garnish your paycheck.
- Refund offset and collection referral — your Connecticut refund can be kept, and the debt can be sent to an outside collection agency.
The IRS runs its own automated sequence — CP14 bill, reminder notices, then a final notice before it can levy. If you've started getting IRS letters, our breakdown of the order of IRS collection letters shows exactly where you stand and how much time each notice buys you.
Your options for Connecticut back taxes
You have more choices than "pay it all today." Which one fits depends on your finances, not on marketing promises.
- State payment plan (DRS installment arrangement) — pay a Connecticut balance over time through myconneCT or by phone. Interest continues, but an active plan stops most enforced collection.
- IRS payment plan — for federal balances under about $50,000, a streamlined installment agreement can usually be set up over up to 72 months. Here's how to set up an IRS payment plan online, step by step.
- Currently Not Collectible / hardship — if paying anything would create real hardship, the IRS can pause collection. Our guide to IRS Currently Not Collectible status explains how it works; DRS reviews hardship situations too.
- Offer in compromise / offer of compromise — both the IRS and Connecticut have a process to settle for less than the full amount when your finances genuinely can't cover it. It's real, but the agency runs the math. Anyone promising to settle your debt for "pennies on the dollar" before they've reviewed your income, expenses, and assets is selling you something.
- Penalty relief — first-time or reasonable-cause relief can remove some penalties, lowering what you owe before you even set up a plan.

How to handle Connecticut back taxes, step by step
- Separate the debts. Confirm your federal balance in your IRS online account and your state balance in myconneCT. Write down the year and amount for each.
- File any missing returns. You can't set up a clean plan or settlement on a balance the agency hasn't calculated. Get unfiled IRS and Connecticut returns filed first.
- Stop the bleeding. Pay what you can toward each balance to slow interest, even if you can't pay in full.
- Pick an option for each agency. A state plan with DRS and a federal plan with the IRS are set up separately — handle both.
- Respond to deadlines on every notice. A state tax warrant or an IRS final levy notice both carry time limits. Don't let one slip while you focus on the other.
- Get a professional review if it's complex. If you owe both the IRS and the state, have several unfiled years, or are facing a levy, the order you fix things in changes what you end up paying.
A quick worked example
Say you owe $8,000 to the IRS and $3,000 to Connecticut DRS, both from a year you filed but couldn't pay. If you ignore it, interest and the federal failure-to-pay penalty (0.5% of the unpaid tax per month) keep stacking on the IRS side, while state interest grows on the DRS side — and either agency can move toward enforcement. If instead you file everything, set up an IRS installment agreement and a DRS payment plan, the enforcement clock stops, and you pay each balance down on a schedule you can actually afford. Same debt, very different year.
Connecticut back taxes: common questions
Who do I owe Connecticut back taxes to — the IRS or the state?
It can be either or both. Federal income tax is owed to the IRS. Connecticut state income tax, sales tax, and similar debts are owed to the Connecticut Department of Revenue Services (DRS). They are separate agencies with separate collection systems, so a plan with one does not settle the other. Check both before assuming you only owe one.
Can Connecticut set up a payment plan for back taxes?
Yes. The Connecticut Department of Revenue Services offers installment payment arrangements through its myconneCT portal or by phone, so you can pay a state balance over time instead of all at once. Interest continues to add up while you pay, but an active plan stops most enforced collection like bank and wage executions.
What happens if I ignore Connecticut back taxes?
DRS can issue a tax warrant, place a lien on your property, levy your bank account, and garnish your wages. The state can also offset your Connecticut tax refund and refer the debt to a collection agency. Interest keeps accruing the entire time. Acting before enforcement starts gives you far more options.
Does Connecticut have an offer in compromise for back taxes?
Connecticut DRS does have an offer of compromise process that can let some taxpayers settle a state debt for less than the full amount when they genuinely cannot pay it. Approval depends on your finances and the facts of your case — no one can promise a settlement before reviewing your income, expenses, and assets.
How many years can Connecticut and the IRS collect back taxes?
The IRS generally has 10 years from the date a tax is assessed to collect it, called the collection statute. Connecticut's collection timeline works differently and a tax warrant can extend how long the state can pursue a debt. Because the rules differ, confirm each agency's deadline rather than assuming the federal 10-year rule applies to your state balance.
