Understanding Your Results
The results above give you a clear snapshot of your financial situation based on the numbers you entered. Here is how to make the most of them:
Look at the big picture first. Start with the summary totals before diving into line-by-line details. This gives you a sense of where you stand overall.
Compare scenarios. Try changing your inputs to see how different situations play out. What happens if your income increases? What if you claim an additional deduction? Playing with the numbers helps you make informed decisions.
Use this as a starting point. These calculations are based on general federal rules and standard rates. Your actual tax situation may differ based on your state, filing status, and specific circumstances. When in doubt, bring these numbers to a tax professional — they make a great conversation starter.

Frequently Asked Questions
What should a freelance invoice include?
A professional invoice should include your business name and contact info, client details, a unique invoice number, date and due date, itemized line items with descriptions and amounts, subtotal, taxes if applicable, total due, and payment terms.
When should I send invoices?
Send invoices immediately upon completing work or according to your contract terms. For ongoing projects, invoice on a regular schedule (weekly, bi-weekly, or monthly). The sooner you invoice, the sooner you get paid.
What payment terms should I use?
Net 30 (due in 30 days) is standard, but many freelancers use Net 15 or even Due on Receipt for faster payment. Consider offering a small discount (2-3%) for early payment to encourage promptness.
