Sales tax calculator
Add sales tax to a price or find the tax inside a total. Put in your combined state and local rate.
To add sales tax, multiply the price by 1 plus the rate: $100 at 8.25% is $108.25. To take it out of a total, divide by 1 plus the rate. The rate is your state rate plus any local rates, and many states don't charge sales tax on most services.
Get paid without chasing
Sam sends invoices and polite, automatic reminders for every unpaid one, including invoices from Xero, QuickBooks, FreeAgent and Sage.

Add tax: price × (1 + rate) · Remove tax: total ÷ (1 + rate)
Worked example
At an 8.25% combined rate, a $500 job comes to $541, with $41.25 sales tax.
Contractors and sales tax
Rules differ a lot by state. In some states, contractors pay sales tax when they buy materials and charge none to the customer; in others, labor or certain services are taxable too. Check your state's department of revenue before you add sales tax to an invoice.
Questions
What sales tax rate should I use?
The combined state and local rate for where the work is done. Your state's department of revenue has a rate lookup.
Do I charge sales tax on labor?
It depends on the state and the type of work. Many states don't tax labor on real property improvements; some do.
Should my quote include sales tax?
Show it as a separate line so the customer sees the price of the work and the tax apart.
