Work It Out
Before You Call
Four tools we built because these are the questions we answer most often. Every figure in them is checked against IRS and California sources, and every one of them tells you what it does not cover.
Tax deadline checker
Every date that applies to you, including the extension deadline and the quarterly payments people forget. Worked out from the federal rules, so it is right even in the years when the fifteenth is not the deadline.
Open the toolDocument checklist
Tick what applies to your year and get the list of what to bring, grouped and printable. The commonest reason a return takes longer than it should is a missing form.
Open the toolLate penalty estimator
What filing or paying late actually costs, including the partnership penalty that applies even when no tax is owed. Shows why filing without paying beats doing nothing.
Open the toolS-corp savings calculator
Compare self-employment tax as a sole proprietor against payroll tax under an S-corporation election, with the California costs that most calculators leave out.
Open the toolThese are free and there is nothing to sign up for. They give general estimates, not tax advice. If a number matters, ask us and we will check it against your actual position at no cost.
