StashTax: Freelance Tax

Know exactly how much tax to set aside from every payment. Log income and deductible expenses, track quarterly estimates and export a clean report. Offline and private.

StashTax is the offline freelance tax calculator and quarterly tax estimator that tells you exactly how much money to set aside from every payment you receive. If you are self-employed, a 1099 contractor, a consultant or a gig worker, a quarterly estimated tax bill should never catch you off guard again.

Most tax apps want your bank login and a subscription. StashTax does neither. It is a private, offline self employment tax calculator: you log what you earn and what you spend, and it estimates the tax to save in real time. Nothing leaves your device.

WHY FREELANCERS LOVE IT

• A clear "set aside this much" number updated as you log income and expenses
• A simple quarterly tax estimator with a countdown to your next due date
• A what-if slider that shows the extra tax to set aside for an upcoming invoice
• No account, no bank connection, no subscription — just open it and go

KNOW WHAT TO SAVE The home screen shows a single, honest figure: how much to move into your tax savings right now, plus your recommended savings rate and what you keep after tax. Adjust an upcoming payment with the what-if slider and instantly see the marginal tax to put aside.

LOG INCOME AND DEDUCTIBLE EXPENSES Track every payment by client and category, and mark it received or invoiced-but-unpaid. Record deductible business expenses — home office, mileage, software, supplies, equipment, marketing, travel, meals, insurance and more — with a deductible percentage and a receipt photo. Your net profit updates instantly.

QUARTERLY AND ANNUAL REPORTS See a per-quarter breakdown of net profit and estimated tax, an annual summary with your effective tax rate, and a deduction breakdown by category. Export a clean tax-prep report as a PDF or CSV to hand straight to your accountant at tax time.

INSIGHTS THAT ACTUALLY HELP A monthly net-profit chart, a logging-activity heatmap, income by weekday and your personal records make it easy to see how your freelance business is really doing across the year.

BUILT FOR ANY COUNTRY StashTax is region-configurable. Use the simple "set aside X%" mode, or switch to the detailed model with a self-employment tax rate and fully editable progressive income-tax brackets, a standard deduction and your own quarterly due dates. Pick your currency from a long list.
