| Anually | For small vendors with a tax liability below $50 per month | Calendar year | January 31 of the following year |
| Monthly | For businesses with a total tax liability of $150 or more per month | Each calendar month | 15th day of the following month |
| Quarterly | For businesses with a tax liability between $50–$150 per month | Jan–Mar, Apr–Jun, Jul–Sep, Oct–Dec | Last day of the month following the quarter |
