Tax calendar

We track your tax deadlines. You don't have to.

The AT portal won't remind you. Neither will Segurança Social. Descodify tracks every deadline that applies to your situation, VAT, IRS, Social Security, e-fatura, the agregado familiar confirmation, and emails you 7 days before each one is due. You focus on your business. We watch the calendar.

We watch. You get reminded.

Every morning, Descodify checks which deadlines are coming up in the next 7 days for every user. If something is due, you get an email. The email tells you what it is, when it's due, and what you need to do.

On your dashboard, each deadline shows up with a checkbox. When you've submitted the declaration on the AT portal or Segurança Social Direta, check it off. Descodify keeps a record of what you've completed and what's still pending. Simple, but it removes the mental load of remembering.

Email reminders are included on the Completo plan. The calendar itself, seeing every deadline and its status, is free on Starter.

Where the numbers come from

The calendar tells you when something is due and whether it applies to you. The amounts themselves are worked out on their own pages.

How VAT is calculated

Rate per invoice, the quarterly breakdown, the recapitulative statement, and the two revenue ceilings that change your regime.

How contributions are calculated

The contribution rate, the income base it applies to, the monthly cap, and the quarter lag that catches people out.

The calendar is free

See every deadline that applies to your situation. No credit card, no trial period. The calendar is part of Starter, free forever.
