Taxes
Free tax calculators for income tax, sales tax, VAT, capital gains, self-employment tax, and property tax.
Estimate your bill, deductions, and refund.
46 calculators covering income tax, capital gains, self-employment, deductions and sales tax. These estimate. They do not file anything, and for anything unusual the arithmetic here is a starting point for a conversation with an accountant rather than a replacement for one.
The most common misunderstanding these pages exist to fix is the marginal rate. Moving into a higher bracket does not tax all your income at the new rate, only the part above the threshold. Nobody has ever taken home less money by earning more, despite how often that is repeated. Every bracket page here shows the tax accumulating band by band, because seeing the split is what actually corrects the belief.
Capital gains splits short-term from long-term, and the gap is large enough to be worth planning around: short-term gains are taxed as ordinary income while long-term rates top out far lower. The holding period boundary is one year and a day, not one year.
Home office compares the simplified rate against the actual-expense method side by side, since which one wins depends on the size of the space and the cost of the home, and people usually pick one out of habit.
Tax pages stay in the currency of the country whose rules they implement, because the brackets are the calculation. That is stated on each page.
