When you are employed, tax is taken before you see your pay. When you are self-employed, every payment you receive is gross income and the tax is entirely your responsibility to calculate, set aside, and remit. Miss a quarterly deadline or underestimate your liability and you face penalties and interest. Our free Tax Tracker logs every payment and shows your estimated tax liability in real-time.
How Self-Employment Tax Works
In the United States, self-employment income is subject to two layers of tax:
- Self-Employment (SE) Tax 15.3% on net self-employment income up to $168,600 (2024), then 2.9% above that. This covers Social Security and Medicare.
- Federal Income Tax applied to the same income at your marginal rate (10–37%).
In the UK, you pay Class 2 and Class 4 National Insurance plus Income Tax via Self Assessment. In most countries the principle is the same: net profit (income minus allowable deductions) is the taxable base.
The 25–30% Rule
A simple, battle-tested rule: set aside 25–30% of every invoice payment in a dedicated savings account the moment it arrives. For higher earners in higher tax brackets, 35% is safer. This single habit eliminates the end-of-year tax shock that catches many freelancers off-guard.
Log every payment platform, amount, currency, date using the Tax Tracker. It calculates your running USD equivalent and estimated tax owed based on Bangladeshi thresholds, adaptable to your own country's rules.
Allowable Deductions That Reduce Your Tax Bill
Most countries allow self-employed individuals to deduct legitimate business expenses:
- Home office (proportional area of rent/mortgage, utilities)
- Software subscriptions (design tools, project management, accounting)
- Hardware and equipment (depreciated or expensed)
- Professional development (courses, books, conferences)
- Accountant and legal fees
- Business insurance
- Bank and payment processing fees
Keep receipts for everything. If you are paid in foreign currencies, convert to your reporting currency at the time of payment using our Currency Converter and record the exchange rate used.
Quarterly Estimated Payments (US)
The IRS expects quarterly estimated payments if you expect to owe $1,000 or more in taxes for the year. Deadlines are typically April 15, June 15, September 15, and January 15 of the following year. The IRS estimated tax guide covers the exact safe-harbour rules to avoid underpayment penalties.
Frequently Asked Questions
What is the self-employment tax rate in the US?
The total SE tax rate is 15.3% 12.4% for Social Security and 2.9% for Medicare applied to 92.35% of your net self-employment income. You can deduct half of the SE tax paid when calculating your income tax.
Do I need an accountant as a freelancer?
Not necessarily for straightforward income, but an accountant typically pays for itself in identified deductions and avoided penalties once your annual income exceeds $40,000–$50,000 (or equivalent). The AICPA maintains a directory of licensed CPAs in the US.
How do I handle tax if I have clients in multiple countries?
You generally pay tax in your country of residence on your worldwide income. If a client withholds tax in their country, you can usually claim a foreign tax credit in your home country to avoid double taxation. Get professional advice if you regularly earn from 3+ jurisdictions.
