The number of charities registered in Ireland surpassed 10,000 for the first time last year, according to the annual report from the Charities Regulator.
Last year was the busiest year for the regulator since it was established in October 2014. The total number of registered charities grew by 7% on 2018.
With that, the number of trustees, the committee members and company directors, grew by 10%.
The 2019 report shows that 2,165 of the 10,514 registered charities reported an annual income of more than €250,000.
More than 875 of those had an income in excess of €1m. This is up from 855 in 2018.
The regulator saw a fall in the number of concerns raised about charities last year.
However, 91% of complaints were about the legitimacy of a charity, governance issues or financial control and transparency.
More than 166 of those concerns related to the issue of bogus clothing collections.
This resulted in a national radio campaign in November, urging members of the public to check the Register of Charities before donating.
Visits to the regulator's website were up 4.25% last year compared to 2018.
The regulator is now focused on the challenges presented by Covid-19.
Chief Executive Helen Martin said her office is monitoring the impact of the pandemic on the sector and said it will provide information and guidance to charities "as they navigate this difficult period".
In May, the Government announced a €40m package of supports for the charity sector due to the virus.
This included a targeted €35m Stability Fund distributed as once-off cash grants to provide immediate short-term cash flow for organisations delivering critical services that have suffered significant income loss due to restrictions.
It also included a €5m Government contribution to a Philanthropy Fund focused on supporting Covid-19 responses that "require innovative and adaptive solutions" to existing and emerging challenges.

Speaking on RTÉ's Morning Ireland, Ms Martin said charities, which are dependent on public support have been really hit hard by a loss of fundraising revenue during the pandemic, and most cannot see how they can fund raise going forward.
She said that those in difficulty have obligations as trustees to meet and make informed decisions, knowing any assets they have must remain in the charitable sector if they cease to operate.
