How Are Bonuses Taxed in Minnesota?

A bonus is additional compensation an employer provides to an employee beyond their regular wages, often recognizing performance or company success. Like all compensation, bonuses are subject to taxes and withholdings, impacting the final amount an employee receives. Understanding these financial obligations helps anticipate the net value of a bonus.

Federal Income Tax Withholding on Bonuses

For federal tax purposes, bonuses are classified as “supplemental wages.” The Internal Revenue Service (IRS) provides employers with specific methods for calculating income tax withholding from these payments. This withholding is an estimate of the tax due, not necessarily the final tax rate applied when annual returns are filed.

One common approach is the flat rate method. If supplemental wages paid to an employee during the calendar year are less than $1,000,000, employers generally withhold federal income tax at a flat rate of 22%. This method simplifies the calculation for employers.

Another method employers might use is the aggregate method. This approach combines the bonus payment with the employee’s regular wages for the current payroll period. The employer calculates the total income tax withholding on this combined amount, then subtracts the withholding on regular wages to determine the amount for the bonus.

The aggregate method can sometimes result in higher withholding in that pay period compared to the flat rate method, depending on the employee’s Form W-4 elections. These are withholding rules designed to collect taxes throughout the year. The actual tax liability for the bonus is ultimately determined when an individual files their annual federal income tax return, based on their total income and applicable deductions and credits.

Minnesota Income Tax Withholding on Bonuses

Bonuses paid to employees in Minnesota are subject to state income tax withholding, similar to regular wages. The Minnesota Department of Revenue requires employers to withhold state income tax from these payments. The specific amount withheld depends on the employee’s Form W-4MN, which provides information about their filing status and claimed allowances.

Employers in Minnesota typically follow principles similar to federal withholding when determining state tax on bonuses. They might apply the state’s withholding rates directly to supplemental wages. Alternatively, they could combine the bonus with regular wages for the pay period, calculating the total Minnesota tax and then backing out the amount attributable to regular wages, mirroring the federal aggregate method.

The goal of Minnesota’s withholding is to ensure state income tax obligations are met throughout the year. While the withholding amount reflects an estimate, the final Minnesota income tax liability for the bonus is determined when the individual files their annual Minnesota income tax return. This final calculation considers all income earned and any applicable deductions or credits.

Social Security and Medicare Taxes on Bonuses

Bonuses are subject to Federal Insurance Contributions Act (FICA) taxes, which fund Social Security and Medicare. These taxes apply to almost all earned income, including supplemental wages. Both the employee and the employer contribute to FICA taxes.

For Social Security, employees generally pay 6.2% of their gross wages, including bonuses, up to an annual wage base limit. This limit changes each year and is the maximum earnings subject to Social Security tax. Once an employee’s cumulative earnings for the year exceed this base, no further Social Security tax is withheld.

Medicare tax does not have a wage base limit. Employees pay 1.45% of all their gross wages, including the full amount of any bonus. An Additional Medicare Tax of 0.9% applies to earned income above certain thresholds: $200,000 for single filers, $250,000 for married couples filing jointly, and $125,000 for married individuals filing separately. This additional tax also applies to bonus income once these thresholds are met.

Understanding Your Net Bonus

When a bonus is paid, the gross amount is reduced by federal income tax withholding, Minnesota income tax withholding, and FICA taxes. This means the net amount an employee receives can appear significantly smaller than the advertised gross bonus. Each type of tax subtracts a portion, leading to a noticeable difference between the bonus amount announced and the direct deposit received.

It is common for individuals to mistakenly believe that bonuses are taxed at a higher rate than regular wages. This perception often arises because the initial withholding on a bonus, especially when the federal flat rate method is used, can seem substantial. However, the amount withheld from a bonus is simply an estimate of the tax owed, not a special, higher tax rate applied uniquely to bonuses.

The bonus is ultimately added to an individual’s total annual income and taxed at their ordinary marginal income tax rate, determined by their overall taxable income for the entire year. Withholding ensures an individual’s tax obligations are met throughout the year, helping to avoid a large tax bill at tax filing time. While the immediate net amount might be lower due to withholding, the bonus is taxed as regular income over the course of the tax year.
