What UAE VAT Threshold Monitor is for

Tests a small business's monthly taxable supplies and imports against the UAE VAT registration thresholds published by the Federal Tax Authority and the Ministry of Finance: AED 375,000 mandatory and AED 187,500 voluntary (supplies and imports, or taxable expenses), over the previous 12 months and for the next 30 days. Shows headroom, the month a growth rate would cross the line, a one-call weekly report, the 5% standard rate with the zero-rated list and the 28-day return rule. The application period after the threshold is met is NOT stated on the pages read and is flagged unverified in every answer. Every threshold names its source, page date and verification level. Group registration, timing of imports and the classification of supplies are not modelled.

Ask your assistant things like:

"My sales were 28,000 to 40,000 a month for the last 12 months: have I crossed the UAE VAT registration threshold?"
"My taxable expenses were about 10,000 a month: can I register for UAE VAT voluntarily?"
"We crossed AED 375,000 on 30 September 2026: by what date do we have to apply for VAT registration?"
"How much room do I have before the UAE VAT threshold and when will I pass it if sales grow 2% a month?"
"Give me this week's UAE VAT threshold check from my monthly sales"
"What is the UAE VAT rate, what is zero-rated, and when is a VAT return due?"

Conventions

Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.
