TaxTab

TaxTab is a sales tax calculator built for small business owners — market vendors, service providers, and anyone who needs to know exactly what to charge and what they owe. CALCULATE BOTH WAYS Add tax to a price, or work backward from a total to find the pre-tax amount. Both directions use the exact same formula your accountant would use — no rounding shortcuts. BUILD REAL TAX PROFILES Create tax profiles for every state, county, and city you sell in. Stack multiple tax components (state + county + city) automatically, or set them up manually if you know your exact rate. Reference data is bundled in for dozens of states — pick yours and go. LOG EVERY TRANSACTION Save any calculation to your log with one tap. Add a note and tag it by category (Retail, Service, Market/Vendor) to keep things organized as your records grow. Tap into any entry to see the full details. SEE THE BIG PICTURE Period Summary rolls your logged transactions up by week, month, or quarter — total taxable sales, total tax collected, and a breakdown by tax profile. Know exactly what you owe before it's time to file. EXPORT WHEN YOU NEED IT Generate a full CSV of every transaction or a clean PDF summary, ready to hand off to your accountant or attach to your filing. COMPARE RATES Selling in more than one jurisdiction? Compare your saved tax profiles side by side to see which rate applies where. YOUR DATA STAYS YOURS No account required. No ads. No tracking. No subscription. Everything is stored locally on your device — TaxTab doesn't have a server, so there's nothing to hack, sell, or lose. Built for people who want a clear, honest picture of the sales tax they collect — and a record they can trust when it's time to file.
