How this works
This tool estimates how much you may owe in taxes based on your income and expenses from self-employment or side hustle activities. When you enter your total income and subtract your business-related expenses, the tool calculates your estimated net income. From there, it estimates:
- Self-employment tax (which covers Social Security and Medicare)
- Federal income tax (based on simplified bracket assumptions)
- A combined estimate of total taxes owed
It also provides guidance on how much you may want to set aside and what your quarterly tax payments could look like — giving you a practical view of your real earnings after taxes, not just your gross income.
Net income
Gross income minus deductible business expenses — what you are actually taxed on.
Self-employment tax
15.3% flat rate covering Social Security (12.4%) and Medicare (2.9%) — owed in addition to income tax.
Federal income tax
Estimated using simplified bracket tiers based on your total combined income.
Quarterly payments
Self-employed individuals typically pay taxes four times per year to avoid underpayment penalties.
Why this is useful
One of the biggest challenges with side income is that taxes are not automatically withheld. Many people underestimate how much they owe and end up with an unexpected tax bill at the end of the year. This tool helps you:
- Estimate your true take-home income
- Avoid underpaying taxes
- Plan ahead with savings targets
- Understand how expenses reduce taxable income
Instead of guessing, you can make informed decisions about pricing, spending, and saving.
If your estimated taxes are higher than expected
This is very common. Self-employment income is taxed differently than regular employment income, and it often includes additional tax obligations. If your estimated taxes feel too high, consider:
- Reviewing and properly tracking all legitimate business expenses
- Increasing how much you set aside regularly
- Adjusting your pricing or income targets to account for taxes
- Breaking your tax amount into smaller monthly or quarterly savings goals
The most important factor is preparation. Taxes are much easier to manage when you plan ahead instead of reacting later.
How to reduce and control your tax burden
While you cannot avoid taxes entirely, there are legitimate ways to reduce what you owe and manage it more effectively. The most important method is tracking and claiming business expenses — software, equipment, home office space, and work-related travel can often be deducted, lowering your taxable income.
- Keep detailed records of all work-related expenses
- Separate personal and business finances to simplify tracking
- Use retirement contributions (SEP IRA or Solo 401k) to reduce taxable income
- Time purchases strategically — for example, buying needed equipment before year-end
- Avoid missed deductions due to poor documentation
Consistency matters. Small deductions add up over time, and regular recordkeeping prevents missed opportunities.
Proven approaches for managing tax obligations
01
Percentage-based set-aside
Consistently set aside 25-35% of all income into a dedicated account before spending any of it.
02
Quarterly planning
Estimate taxes throughout the year and make payments every three months instead of facing a lump sum later.
03
Separate tax account
Immediately move a portion of every payment into a different account so it is never accidentally spent.
04
Income smoothing
Use higher-earning periods to cover slower months and future tax obligations. Consistency over reaction.
Frequently asked questions
What is self-employment tax and why is it 15.3%?
Self-employment tax covers Social Security (12.4%) and Medicare (2.9%), totaling 15.3%. When you work as an employee, your employer pays half of these taxes on your behalf. As a self-employed person, you pay both halves yourself. This is in addition to federal income tax, which is why the total tax burden for self-employed individuals is often higher than people expect.
Do I have to make quarterly tax payments?
Generally yes, if you expect to owe at least $1,000 in federal taxes for the year. The IRS requires self-employed individuals to pay estimated taxes quarterly rather than waiting until April. The due dates are typically April 15, June 16, September 15, and January 15. Failing to pay quarterly can result in underpayment penalties, even if you pay everything owed by the April filing deadline.
What counts as a deductible business expense?
Business expenses are costs that are ordinary and necessary for your work. Common examples include software subscriptions, equipment and tools, home office space (if used exclusively for work), internet and phone (the business-use portion), professional services, and work-related travel. Personal expenses are not deductible. Keeping detailed records and receipts is essential — the IRS requires documentation for all deductions claimed.
How is this estimate different from what I will actually owe?
This tool uses simplified bracket tiers and assumes single-filer status. Your actual tax liability depends on your filing status, the standard deduction or itemized deductions, other credits and deductions, state income taxes, and whether you qualify for the 20% qualified business income (QBI) deduction. This estimate is a useful planning tool but should not replace advice from a tax professional for your actual return.
What is the recommended 25-30% set-aside rule?
A common rule of thumb for self-employed individuals is to set aside 25-30% of every payment received into a dedicated account reserved for taxes. This covers both self-employment tax and federal income tax for most people in lower to middle income ranges. If your income is higher or you live in a state with income tax, 30-35% may be more appropriate. The key is to move the money immediately before it gets spent.
Can I deduct half of my self-employment tax?
Yes. The IRS allows self-employed individuals to deduct half of their self-employment tax from their gross income when calculating their adjusted gross income (AGI). This deduction is taken on your federal tax return and reduces your taxable income, which in turn reduces your federal income tax. This tool uses simplified estimates and does not model this deduction — a tax professional or tax software will apply it automatically when you file.
