Receiving a notice that you owe money, despite claiming tax credits, usually means you received an overpayment, claimed a credit you weren't eligible for, or had your refund offset to pay other debts. Common causes include income changes, filing errors, or failing to reconcile advance payments like the Premium Tax Credit.
If you are owing the IRS money then you are not withholding enough throughout the year, or you are not filing your taxes correctly. There is no good reason anyone with one allowance should wind up underwithheld throughout the year assuming your employer withholds according to the IRS formulas.
You can be overpaid tax credits even if you told HM Revenue and Customs ( HMRC ) about a change of circumstances on time. You'll normally have to repay these. Disputes are usually only successful if HMRC made a mistake.
If your income is more than what you told us on your application, you may have to repay some or all of the advanced premium tax credits that you got. There are limits to the amount you may need to repay, depending on your income and if you file taxes as “Single” or another filing status.

Tax credits are amounts you subtract from your bottom-line tax due when you file your tax return. Most tax credits can reduce your tax only until it reaches $0. Refundable credits go beyond that to give you any remaining credit as a refund. That's why it's best to file taxes even if you don't have to.
If at the end of the year you've taken more premium tax credit in advance than you're due based on your final income, you'll have to pay back the excess when you file your federal tax return. If you've taken less than you qualify for, you'll get the difference back.
To help prevent an overpayment, you must notify us if you:

The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.
For used vehicles, the credit amounts to 30% of the vehicle's price, up to a maximum of $4,000. Unlike a tax deduction, which reduces your taxable income, a tax credit directly reduces your tax bill. For example, if you qualify for the maximum $4,000 credit, it reduces your tax bill by that amount.
You likely received $1400 from the IRS today as a supplemental payment for the 2021 Economic Impact Payment (EIP3), specifically the Recovery Rebate Credit, for people who missed it by not claiming it or leaving it blank on their 2021 tax return. These are "plus-up" payments for those eligible for the third stimulus but didn't get the full amount, often for dependents or due to income changes, with a deadline to claim it by April 2025 by filing a 2021 return if you hadn't already.
Tax credits work by directly reducing the amount of income tax you owe, dollar-for-dollar, potentially lowering your tax bill or increasing your refund, unlike deductions which lower your taxable income. Credits are categorized as nonrefundable, meaning they can only reduce your tax owed to $0 (e.g., Child and Dependent Care Credit), or refundable, allowing you to get money back even if you owe no tax (e.g., Earned Income Tax Credit, Additional Child Tax Credit). You claim them when filing your tax return by completing forms or answering questions in tax software.
You must let HMRC know if your income varies so they can adjust your tax credit payment. This stops overpayments in the next tax year. Let HMRC know of any changes on 0345 300 3900.
