grotax_compute_ctread-onlyEstimate UAE Corporate Tax using the Grovisor computation (rows A–K): AED 375,000 0% band then 9%, 50% entertainment add-back, interest cap (higher of AED 12m or 30% of adjusted EBITDA), 75% loss relief, Small Business Relief, simplified QFZP and WHT/FTC credits. Only accountingProfit is required; pass revenue to test SBR. Returns a markdown table plus structured rows. Indicative, not tax advice.
grotax_health_checkread-onlyRun the Grovisor CT reviewer red-flag checklist (SBR, free zone/QFZP, TP disclosure and Local/Master File, connected-person pay, related-party loans, entertainment, fines, interest cap, loss continuity, audit threshold, exempt income). Pass the answers you know; call grotax_list_health_questions first for the keys and allowed values. Returns findings ranked High → Low.
grotax_list_health_questionsread-onlyList the groTAX health-check questions with their answer keys and allowed values, including which questions only apply after others (dependsOn). Use before grotax_health_check.
grotax_tp_thresholdsread-onlyCheck which UAE transfer pricing documents apply: TP Disclosure Form (related-party transactions > AED 40m with a category > AED 4m, or connected-person payments > AED 0.5m), Local File + Master File (revenue > AED 200m or MNE group).
grotax_compare_sbrread-onlyCompute the same facts with and without Small Business Relief (revenue ≤ AED 3m, periods ending by 31 Dec 2029). Shows tax payable and what carries forward each way: in an SBR year a tax loss and disallowed interest are forfeited. Takes the same inputs as grotax_compute_ct (sbrElect is ignored).
grotax_penaltiesread-onlyReturn and payment due date (9 months after period end) and estimated penalties: late filing AED 500 a month for 12 months then AED 1,000, late payment 14% a year charged monthly (from 14 Apr 2026), AED 10,000 late registration, waived if the first return is filed within 7 months of the end of the first tax period. Blank filing date = today; blank payment date = filing date.
grotax_qfzp_de_minimisread-onlyTest whether a free zone company's non-qualifying revenue stays within the de minimis limit: the lower of 5% of total revenue or AED 5m (MD 229 of 2025). Failing it ends Qualifying Free Zone Person status for that period and the next 4.
grotax_get_rulesread-onlyList every rate and threshold groTAX uses, with its legal source and whether it still needs verification (verify: true).
