The Welsh Rugby Union Group recorded increased pre-tax profits of £27.6million last year on the back of a record £58.5million turnover.
The 2010 annual report shows the WRU's profits rose from £24.5million and their total income increased by 18%, helped by eight home internationals at the Millennium Stadium.
Chief executive Roger Lewis said: "I am delighted at the success we have again achieved against the backdrop of an economic environment which remains challenging. We have been able to grow the business in terms of income and this has allowed us to make radical and forward looking decisions which will benefit the future of the game in Wales."
The WRU ploughed £20million directly back into the game. The four professional regions received a combined total of £14.2million while £1.3million went to the semi-professional Premiership clubs.
The community game was allocated £4.5m, including a one-off investment of £1.0m in rugby equipment. The WRU also reduced their bank debt to £26.7m and extended their property portfolio in Cardiff.
That £2.3million investment covered the acquisition of the lease for the Cardiff Arms pub, improvements to the stadium and projects covering the WRU's new centre of excellence.
Lewis added: "I am extremely mindful that our three core priorities are elite rugby, the community game and the Millennium Stadium so we have to devise polices and strategies which sustain and develop them all.
"We have to have a strong community game to deliver the supporters and players who fill the Millennium Stadium to follow our national teams.
"The range of successful initiatives and projects outlined in our Annual Report all align to our core aims which are to do the best we can for Welsh rugby. There are exciting and challenging times ahead, but I am confident we have the right people and the correct strategies and systems in place to look forward with confidence."
The WRU has secured broadcasting contracts with the BBC, BBC Wales and S4C and agreed a new shirt sponsorship deal with Admiral.
