Tax & ZUS, in the month you pay them
October’s tax and ZUS are due by 20 November, so they belong to November’s plan. This month’s amount still shows, so you can set it aside, and real figures from your accountant replace the estimates.


Your JDG, your job, your bank accounts, investments and taxes, together at last. Saldo shows what is really yours each month, in plain English.






Days billed, payslips, invoices, bills and balances go in. One clear answer comes out: what is really yours this month.
Tell Saldo how you earn and it asks only what matters for you. Switch any time.
Log the days you bill. Saldo turns them into income tax, ZUS and health estimates, and checks your KSeF invoices against them.


Add your gross salary and Saldo works out every payslip, and whether the yearly tax return will ask for more or give some back.


In months your job pays at least the minimum wage, your JDG pays no social ZUS. Saldo knows, and keeps both incomes in one plan.
