You might have two supplemental tax bills because you didn’t pay enough taxes initially, which could be due to several reasons. Perhaps your income was higher than expected, or you claimed too many deductions. Alternatively, it’s possible that you didn’t withhold enough taxes from your paychecks throughout the year. Additionally, if you received a tax refund last year that you weren’t entitled to, the IRS may issue a supplemental bill to recover the funds. To avoid future supplemental bills, make sure to accurately estimate your tax liability and adjust your withholdings accordingly. You can also consider making estimated tax payments throughout the year to ensure that you’re paying your taxes evenly.
Why Do I Have Two Supplemental Tax Bills
You may have received multiple supplemental tax bills if you have income from different sources. The IRS requires taxpayers to file a separate tax return for each type of income. When a taxpayer has income from different sources in different tax years, they may be required to pay taxes on those earnings.
Multiple Income Sources
The most common reason an individual may have multiple supplemental tax bills is because they have income from various sources. These sources include:
- Wages or salary
- Self-employment
- Investments
- Retirement accounts
- Rental properties
Each individual income source requires its own tax filing requirements. As a result, individuals may end up owing taxes on each earnings type. This can lead to multiple supplemental tax bills.
Example of Multiple Income Sources
To demonstrate income from different sources, consider the following example. Suppose a taxpayer earns a salary of $50,000 per year, has self-employment income of $20,000, and receives $5,000 in interest income. In this instance, they will need to file three separate tax returns:
- Form W-2 for their salary income
- Schedule C for their self-employment income
- Schedule B for their interest income
Based on their income and applicable tax rates, the taxpayer may be required to pay taxes on each income source. Depending on the specific circumstances, this could result in multiple supplemental tax bills.
Table: Types of Income and Tax Filing Requirements
| Income Type | Tax Filing Requirement |
|—|—|
| Wages/salary | Form W-2 |
| Self-employment | Schedule C |
| Investments | Schedule B |
| Retirement accounts | Form 1099-R |
| Rental properties | Schedule E |
## Why Do I Have Two Supplemental Tax Bills
There are a few reasons why you might have received two supplemental tax bills.
Underpayment of Estimated Taxes
If you did not pay enough estimated taxes throughout the year, you may owe a penalty. Estimated taxes are required if you expect to owe more than $1,000 in taxes for the year. You can make estimated tax payments using Form 1040-ES.
The penalty for underpayment of estimated taxes is calculated as follows:
* **Individuals:** 0.5% of the tax that should have been paid, multiplied by the number of days the payment was late (up to 45 days).
* **Businesses:** 0.5% of the tax that should have been paid, multiplied by the number of days the payment was late (up to 90 days).
**Example:**
If you should have paid $1,000 in estimated taxes and you paid only $750 on time, you would owe a penalty of $12.50 (0.5% x $250 x 50 days).
You can avoid the penalty for underpayment of estimated taxes by:
- Making estimated tax payments timely.
- Paying at least 90% of your tax liability for the year through estimated tax payments.
- Owing less than $1,000 in taxes for the year.
Other Reasons for Two Supplemental Tax Bills
* **Error on your tax return.** The IRS may have made an error when processing your tax return, which could result in you receiving a supplemental tax bill.
* **Change in your tax situation.** If your tax situation changed during the year, you may owe additional taxes. For example, if you received a large inheritance, you may need to pay additional taxes on the income from the inheritance.
* **Audit of your tax return.** If the IRS audits your tax return, they may determine that you owe additional taxes.
**If you have received two supplemental tax bills, you should contact the IRS to determine why.** The IRS can help you resolve the issue and make sure that you are paying the correct amount of taxes.
Tax Return Errors
- Incorrect AGI: Ensure the AGI reported on your tax return matches the amount on your W-2, 1099, and other income documents.
- Math Errors: Carefully review your tax calculations for errors in addition, subtraction, multiplication, and division.
- Missing or Incorrect Deductions/Credits: Verify that all eligible deductions and credits are claimed and that the amounts are correct.
- Mistakes on Schedules: Double-check that information reported on schedules, such as Schedule A or Schedule C, is accurate.
Other Factors
- Identity Theft: If you suspect someone fraudulently filed a tax return in your name, report it to the IRS immediately.
- Tax Audits: The IRS may conduct audits to review tax returns for accuracy. If you receive a notice of an audit, respond promptly and provide the requested information.
- Estimated Tax Payments: If you underpaid your estimated taxes, you may receive a supplemental tax bill to cover the shortfall.
Proactive Measures
- Hire a Tax Professional: Consider consulting a tax professional to review your tax returns and ensure accuracy.
- Use Tax Software: Utilize reputable tax software that can assist in identifying errors and calculating your taxes correctly.
- Keep Records: Maintain a well-organized file with all necessary tax documents for future reference.
Changes to Tax Law
Several recent changes to the tax law have made it more likely that you may receive two supplemental tax bills. These changes include:
- The Tax Cuts and Jobs Act (TCJA) of 2017
- The American Rescue Plan Act (ARPA) of 2021
- The Inflation Reduction Act (IRA) of 2022
TCJA
The TCJA made significant changes to the tax code, including increasing the standard deduction and reducing the number of tax brackets. These changes resulted in many taxpayers receiving a smaller refund or owing more taxes than they expected.
ARPA
The ARPA provided for economic stimulus payments in response to the COVID-19 pandemic. These payments were not initially taxable, but they were later made taxable by the TCJA. This means that some taxpayers who received stimulus payments may now owe additional taxes.
IRA
The IRA made changes to the tax code related to climate change and healthcare. These changes may also result in some taxpayers receiving a smaller refund or owing more taxes than they expected.
Supplemental Tax Bills
If you owe additional taxes, you may receive a supplemental tax bill from the IRS. These bills are typically sent out in the spring or summer, and they will include instructions on how to pay your balance due.
What to Do If You Receive a Supplemental Tax Bill
If you receive a supplemental tax bill, you should review it carefully to make sure that it is accurate. If you believe that you do not owe the taxes that are being claimed, you can contact the IRS to dispute the bill.
You can also take the following steps to avoid receiving supplemental tax bills in the future:
- Make sure that you are withholding enough taxes from your paycheck.
- Estimate your taxes quarterly and make estimated tax payments if necessary.
- File your tax return on time and pay any taxes that you owe.
| Law | Key Changes |
|---|---|
| TCJA | Increased standard deduction, reduced tax brackets |
| ARPA | Provided for economic stimulus payments, which were later made taxable by the TCJA |
| IRA | Made changes to the tax code related to climate change and healthcare |
