🟢gst_hst_small_supplier_check(quarters, taxiOrRideshare)
Apply the CRA's $30,000 small-supplier tests (single calendar quarter and four consecutive calendar quarters) to taxable revenue by calendar quarter. Says whether the person must register for the GST/HST, when they stop being a small supplier, the effective date of registration, and headroom for next quarter. Most businesses only (not charities/public service bodies).
