When it comes to calculating annual income, knowing your hourly wage is just the first step. The real question is: How much will you take home after taxes, deductions, and other factors? For example, if you earn $31.50 per hour, how does that translate to your annual earnings after federal and state taxes? This question requires a deep dive into the tax system, deductions, and how various factors influence your net income. In this article, I will walk you through a detailed breakdown of how much $31.50 an hour is per year after taxes, considering the different components that impact take-home pay.

Step 1: Gross Annual Income Calculation
Before delving into taxes and deductions, it’s essential to first calculate the gross annual income. The gross income is simply the amount you make before any deductions, such as taxes, Social Security, or Medicare.
To calculate your gross annual income, we use the following formula:
\text{Gross Annual Income} = \text{Hourly Rate} \times \text{Hours per Week} \times \text{Weeks per Year}For someone earning $31.50 per hour, and assuming a full-time schedule of 40 hours a week for 52 weeks a year (no time off), the calculation would be:
31.50 , \text{USD/hour} \times 40 , \text{hours/week} \times 52 , \text{weeks/year} = 65,520 , \text{USD/year}Therefore, before any deductions, your gross annual income is $65,520.
Step 2: Federal Income Tax Deductions
The next step is to account for federal income taxes, which are based on the IRS’s progressive tax system. The U.S. federal tax system taxes income in brackets, meaning the more you earn, the higher your effective tax rate will be. For the 2025 tax year, the federal income tax brackets for a single filer are as follows:
- 10% on income up to $11,000
- 12% on income from $11,001 to $44,725
- 22% on income from $44,726 to $95,375
- 24% on income from $95,376 to $182,100
- 32% on income from $182,101 to $231,250
- 35% on income from $231,251 to $578,100
- 37% on income over $578,100
For this example, we will assume you are filing as a single person with no dependents and taking the standard deduction of $13,850 in 2025. Let’s now calculate the taxable income:
65,520 , \text{USD} - 13,850 , \text{USD} = 51,670 , \text{USD}Now, let’s calculate the federal tax owed based on the progressive tax brackets.
- The first $11,000 is taxed at 10%:
The next $33,725 (from $11,001 to $44,725) is taxed at 12%:
33,725 \times 0.12 = 4,047 , \text{USD}The remaining $6,945 (from $44,726 to $51,670) is taxed at 22%:
6,945 \times 0.22 = 1,528 , \text{USD}So, the total federal income tax would be:
1,100 + 4,047 + 1,528 = 6,675 , \text{USD}Step 3: State Income Tax Deductions
State income tax varies from state to state. Some states, like Texas, Florida, and Washington, do not charge any state income tax, while others, like California and New York, impose significant state taxes. For the sake of this example, let’s calculate the state income tax in California, which has the following state income tax brackets for a single filer in 2025:
- 1% on income up to $10,099
- 2% on income from $10,100 to $23,942
- 4% on income from $23,943 to $37,788
- 6% on income from $37,789 to $52,455
We’ll calculate the state income tax based on the taxable income of $51,670. Here’s the breakdown:
- The first $10,099 is taxed at 1%:
The next $13,843 (from $10,100 to $23,942) is taxed at 2%:
13,843 \times 0.02 = 276.86 , \text{USD}The next $13,845 (from $23,943 to $37,788) is taxed at 4%:
13,845 \times 0.04 = 553.80 , \text{USD}The remaining $13,882 (from $37,789 to $51,670) is taxed at 6%:
13,882 \times 0.06 = 832.92 , \text{USD}The total California state income tax would therefore be:
100.99 + 276.86 + 553.80 + 832.92 = 1,764.57 , \text{USD}Step 4: Social Security and Medicare Taxes
In addition to federal and state taxes, every employee in the U.S. contributes to Social Security and Medicare, which are known collectively as FICA taxes. As of 2025, these rates are:
- Social Security: 6.2% of your income up to $160,200
- Medicare: 1.45% of your entire income, with no income cap
Let’s calculate these deductions on your $65,520 annual salary.
- Social Security tax:
Medicare tax:
65,520 \times 0.0145 = 949.04 , \text{USD}Step 5: Total Tax Deductions
Now, let’s sum up all the taxes you will owe:
- Federal tax: $6,675
- State tax (California): $1,764.57
- Social Security tax: $4,062.24
- Medicare tax: $949.04
The total tax deductions would be:
6,675 + 1,764.57 + 4,062.24 + 949.04 = 13,450.85 , \text{USD}Step 6: Net Annual Income After Taxes
To calculate your net income after all deductions, simply subtract the total taxes from your gross income:
65,520 - 13,450.85 = 52,069.15 , \text{USD}So, after taxes, your net annual income would be approximately $52,069.15.
Step 7: Comparison with Other Hourly Wages
It’s helpful to see how $31.50 per hour compares to other hourly wages in terms of net income. Below is a table showing the net income for various hourly wages, assuming the same 40-hour workweek and 52-week work year, along with the same tax rates (federal, California state, and FICA):
| Hourly Rate | Gross Annual Income | Federal Tax | State Tax (CA) | Social Security | Medicare | Total Tax Deductions | Net Annual Income |
|---|---|---|---|---|---|---|---|
| $31.50/hour | $65,520 | $6,675 | $1,764.57 | $4,062.24 | $949.04 | $13,450.85 | $52,069.15 |
| $35/hour | $72,800 | $7,722 | $2,011.75 | $4,513.60 | $1,055.60 | $15,303.95 | $57,496.05 |
| $40/hour | $83,200 | $9,143 | $2,323.75 | $5,158.40 | $1,208.00 | $17,833.15 | $65,366.85 |
As you can see, a higher hourly wage results in a higher net annual income, but also leads to more taxes due to the progressive tax system.
Step 8: Financial Planning Considerations
When you’re earning $31.50 per hour, it’s crucial to think beyond just your take-home pay. In particular, financial planning should include the following elements:
- Retirement Savings: Contributing to a 401(k) or an IRA can help you reduce your taxable income and save for the future.
- Health Insurance: If your employer offers health insurance, it may be deducted pre-tax, reducing your taxable income.
- Emergency Fund: With a net income of around $52,069 per year, it’s wise to start building an emergency fund to cover 3-6 months of living expenses.
Conclusion
Earning $31.50 per hour results in a gross annual income of $65,520. After accounting for federal, state (California), and FICA taxes, your net annual income comes out to approximately $52,069.15. This figure provides a good starting point for budgeting, saving, and planning for the future. Understanding how taxes and other deductions impact your earnings is crucial for making informed financial decisions. By considering factors like retirement savings, health insurance, and an emergency fund, you can optimize your finances for the long term.
