How to fix eCAC not working
eCAC is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:
Your browser tries to reach cav.receita.fazenda.gov.br over your own connection, right now. Nothing is sent to us or stored.
Open eCAC through gov.br
Open a private window with Ctrl+Shift+N in Chrome or Edge, or Ctrl+Shift+P in Firefox, then go to https://cav.receita.fazenda.gov.br and choose Entrar com gov.br. If the password or two-step prompt fails, use Esqueci minha senha on the gov.br page before trying the portal again.
Clear Receita cookies
In Chrome or Edge, open chrome://settings/siteData or edge://settings/siteData, search for receita.fazenda.gov.br and acesso.gov.br, and remove the stored data for those sites. Close the browser, open it again, and sign in from cav.receita.fazenda.gov.br so gov.br creates a fresh session.
Allow Receita pop-ups
Chrome and Edge can block new windows that the portal uses for pages, receipts, or downloads. In Chrome, open Settings > Privacy and security > Site settings > Pop-ups and redirects; in Edge, open Settings > Cookies and site permissions > Pop-ups and redirects. Add https://cav.receita.fazenda.gov.br under the allowed list, then repeat the action that failed.
Check your digital certificate
If you choose certificate access, plug in the token or card reader before opening the browser. On Windows, press Win+R, run certmgr.msc, and check Personal > Certificates for a valid ICP-Brasil certificate issued to your CPF or CNPJ. If it is missing, reinstall the certificate chain and token or card driver from your certificate issuer, then restart the browser.
While eCAC is down: what to use instead
- Receita Federal site Use the public pages for CPF, CNPJ, certidões and downloads when the task does not need an eCAC session.
- Meu Imposto de Renda For income tax work, the Receita app or desktop program can help you prepare or send a declaration while the portal is failing.
- SicalcWeb If you only need to calculate or issue a DARF, SicalcWeb is the safer fallback than waiting inside the portal.
- Receita Federal atendimento For deadlines, identity issues or a blocked account, use Receita Federal service scheduling instead of retrying the same page all day.
Problems at the same time as eCAC
Since 3 November, all 2 of eCAC's spikes in problem reports overlapped a spike at another service.
When several services get problem reports at once, something they share, such as a cloud host or a network, can be the real cause. Matching times alone do not prove it.

What happens when eCAC goes down
eCAC is the Receita Federal do Brasil online service portal at cav.receita.fazenda.gov.br, used by individual taxpayers, businesses, accountants, and legal representatives in Brazil. An outage can interrupt gov.br sign-in, access to tax records, electronic case files, and requests such as payment plans or refunds.
Login trouble often shows up first, with the page sending you back to sign-in or stalling after gov.br authentication. Inside the portal, consultas, Caixa Postal, procurações eletrônicas, and processo digital pages may load slowly or fail after you submit a form. Some failures affect only one Receita Federal service while the main portal still opens, so a partial problem is common. Regional reports can happen, but many incidents look tied to the specific back-end service you are trying to use.

Tip: eCAC doesn't list a public status page that we know of, so its help centre and the report chart on this page are the best places to check.
How we track eCAC
The status on this page comes from user-submitted problem reports for eCAC, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for eCAC, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.
When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. eCAC doesn't publish a public status page that we know of, so user reports are often the quickest sign that something is wrong on their side.
