ONT-TAXS, Ontario's Tax Services
At the Ministry of Revenue we are addressing the changing needs of Ontario's 600,000 tax clients. We are making it simpler for Ontario businesses to comply with their tax obligations – less paper, more connected and less hassle.
The ministry is introducing new and improved Ontario Tax Services, or ONT-TAXS, which includes:
- one toll-free number;
- one business number;
- new Internet services – ONT-TAXS online – providing self-serve options; and
- system improvements to facilitate one-window service delivery.
The new toll-free number 1 866 ONT-TAXS was launched in June 2008.
All of these new services are expected to be fully implemented by 2010.
