## What is Quarterly Taxer?

QuarterSafe is the quarterly tax copilot for US freelancers, 1099 contractors, and gig workers. Log income in two taps and see exactly how much to move into your tax jar - with every IRS deadline counted down on your Lock Screen.

The IRS fine print trips up millions of self-employed people every year: quarters that are not really quarters, deadlines that shift for weekends and holidays, the 15.3% self-employment tax everyone forgets, and penalty math that quietly adds up to $1,000 or more. QuarterSafe handles all of it so you can stop worrying and pay on time.

KEY FEATURES

- US deadline engine: all four federal estimated tax deadlines for 2026, with weekend and federal holiday shift rules applied automatically. Q2 really is just 8 weeks after Tax Day - QuarterSafe never lets it sneak up on you.

- Two-tap income logging: enter what a client paid you and instantly see "this one: save $312". Every payment you log updates your quarter target on the spot.

- Smart reminder chain: friendly notifications at 21, 14, 7, and 1 day before each deadline, plus deadline day itself. The moment you mark a quarter as paid, the remaining reminders cancel themselves - no nagging after you have paid.

- Safe Harbor precision engine (Pro): real compliance math that follows IRS rules - 90% of this year, 100% or 110% of last year, whichever is lower, plus the $1,000 small-balance exemption and the high-income AGI tier. No guesswork.

- Simple 30% mode (free): no last-year numbers yet? QuarterSafe falls back to a conservative 30% reserve estimate and tells you honestly that it is a simple mode.

- Tax jar with carryforward: watch your jar fill as you set money aside. Overpaid a quarter? The extra rolls into the next one automatically.

- Payment ledger and proof vault: record every estimated payment with the method (IRS Direct Pay, EFTPS, check, or other), the confirmation number, and an optional proof photo from your library.

- Tax Proof Pack PDF (Pro): one tap exports an audit-ready PDF of every payment - dates, amounts, confirmation numbers, and your proof photos indexed - the record the IRS cannot dispute.

- Payment jump-off to IRS Direct Pay: open the official IRS payment site in one tap. QuarterSafe never touches your money or asks for a bank connection.

- Lock Screen widget: see the next deadline countdown and your jar progress without opening the app.

- All 50 states plus DC: state tax estimates with flat-rate and no-income-tax states handled, and quarterly reminders tuned to your state.

- Private by design: no account, no sign-up, no analytics, no bank connection. Everything stays on this iPhone.

FREE VS PRO

Free: deadline countdown, the full reminder chain, income and expense logging, the 30% simple calculator, the basic Lock Screen widget, and the payment ledger.
