Almost €6.57 billion in tax was received by the Exchequer in July, up €303m (4.6%) on the same month of last year.
Figures from the Department of Finance show Corporation Tax take continuing to surge, with €333m taken in the month.
That is €101m - or 43.3% - more than in July 2022.
Income tax receipts were €217m (8.7%) higher year-on-year, at €2.7 billion.
Meanwhile €2.93 billion was received in VAT, up €136m (4.9%) on July 2022.
It means that almost €47.8 billion has been received by the Exchequer so far this year - up €4.34 billion (10%) on the first seven months of 2022.
Corporation tax take is €1.87 billion (20.7%) higher so far this year at almost €10.9 billion.
Income taxes are €1.48 billion (8.8%) higher at €18.22 billion, while €13.2 billion has been received in VAT; up €1.36 billion (11.5%).
However there has been a decline in some other tax categories in the first seven months of the year.
Stamp duties are currently €289m (26.4%) lower year-on-year at €806m.
Capital gains tax take is down €105m (21.6%) to €382m, while capital acquisitions taxes are down €16m (10.2%) at €141m.
Overall the Exchequer recorded a €700m surplus in the year to the end of July, compared to a €5 billion surplus in the same period of last year.
The Department of Finance said the bulk of this difference was due to the transfer of €4 billion to the National Reserve Fund.
On a 12-month rolling basis, the Exchequer surplus was also at €700m.
However when one-off factors - including what is estimated to be "excess" corporation tax take - are excluded, the department says there is an underlying deficit of around €6 billion.
The figures show that total Exchequer expenditure stood at €58.7 billion by the end of July.
Gross voted expenditure represented €49.2 billion of that - up €3.9 billion (8.6%) year-on-year.
Non-voted expenditure made up the remaining €9.5 billion - which is €1.6 billion (20.2%) more than a year ago.
"July is traditionally not a key month for corporation tax but receipts for the month are still up on last year indicating that profitability in the corporate sector continues to hold firm," said Tom Woods, head of tax at KPMG.
"Total VAT receipts in the year to date at €13.2 billion are well on track to meet the Government's €20.4 billion projected VAT take for 2023.
"Cumulative income tax receipts are also on target to achieve the forecasted €32.8 billion income tax take for the full year."
"VAT receipts dipped slightly in May and there was more evidence of a decline in spending in the July figures," said Peter Vale, tax partner at Grant Thornton Ireland. "While ahead of last year, the more muted VAT receipts likely reflect the impact of both higher interest rates and utility costs on discretionary spending power.
"Income tax receipts remain strong, running almost 9% instead of the same period in 2022, although there is a small decline in the rate of increase. While the economy remains close to full employment, the loss of some highly paid roles in the multinational sector may be reflected in the figures."
Reacting to the figures, acting chair of the Irish Fiscal Advisory Council Professor Michael McMahon said the economy is "doing pretty well".

Speaking on RTÉ's Morning Ireland, Professor McMahon said the latest numbers show that despite inflation and the challenges on cost of living and cost of business, the Irish economy is "doing pretty well and is pretty close to or above its full employment levels."
He said the figures were "good news" and they give the public coffers a boost.
"But that doesn't mean that the Government should just decide to immediately spend them," he added.
"It's absolutely right that elected officials in a democracy make the decisions and that's ultimately what does always happen in Ireland," Professor McMahon said.
But he added that the one reason the Irish Fiscal Advisory Council is around is that we should ignore the politics of it and give the advice on the basis of "what's right to do now".
The Professor said Ireland is in a really fortuitous position and one that other countries would love to have.
He said that July is not a particularly important month for corporation tax because of the nature of the timing of when companies file.
But, he said, the numbers are up quite a lot, but other months we have seen even bigger nominal amounts.
"This is still going to be a very good year for corporation tax with a lot of it emanating outside of the Irish economy," he stated.
He explained that other countries, when they have discovered oil reserves for example, have spread the resources from that across many years and have the resource pay off for many generations by putting them into a savings vehicle.
The Government has indicated, and the IFAC has argued for a long time that that is a route that they are going to go down, he said.
"There's a lot of detail still to work out. Now our particular preference is to put it into something that is earmarked for age-related spending that we know is coming 20 years down the road," he said.
