Frequently asked questions
How much should I set aside for taxes as a freelancer?
A common rule of thumb is 25–35% of every payment. In the US, self-employment tax alone is 15.3% on the first ~$168k (2025), plus federal and state income tax. In the UK, most sole traders pay 20% basic-rate income tax on profits, with higher rates above £50k. This estimator uses your actual numbers instead of the rule of thumb — and exports the due dates to your calendar.
When are quarterly tax payments due?
US (IRS estimated payments): April 15, June 15, September 15, January 15. UK (self-assessment): two payments on account by January 31 and October 31, plus the balancing payment by January 31. Canada (installments): typically March, June, September, December (or the 15th of the month after your tax year, depending on your method). Australia: BAS/IAS lodgement dates monthly or quarterly. The tool lists the dates that apply to you.
What deductions can freelancers claim?
The big ones: home office (portion of rent/mortgage + utilities), business equipment and software, a share of internet and phone, mileage or travel for client work, professional development, insurance, and accounting fees. Track expenses from day one with the Expense Deduction Tracker — deductions you can't document are deductions you can't claim.
