Corporate Tax Estimator for UAE SMEs

A small business owner or accountant often needs to answer one question before year end: roughly how much corporate tax will we owe, and can I show the working. Doing it in a spreadsheet means rebuilding the bridge every time and trusting a formula nobody has audited. This app does the arithmetic in one file you open by double-clicking, keeps your numbers on your device and prints the whole computation on one A4 page.

The design rule is honest: the app contains no built-in corporate tax rate, band, threshold or relief rule. The only fact it states is that a federal corporate tax exists in the UAE and is administered by the Federal Tax Authority. Everything else is a setting that you enter after confirming it with the FTA or your tax adviser. The Load example data button fills invented numbers so you can see it working; they are labelled example only and are not the real rates.

What is inside

• Profit to taxable income bridge: accounting profit (entered, or revenue plus other income less expenses), add-back and deduction rows with a type checklist, taxable income before losses.
• Tax losses brought forward with an optional utilisation limit you enter, losses used, losses left, and any tax loss arising in the period.
• Tax by band: any number of bands you enter (from, to, rate), progressive slices shown, rounded once at the end, half up.
• Small business relief check: a checklist driven by your settings (availability, revenue threshold, prior period revenues, a list of conditions you enter and tick, and the effect you choose).
• A list of prompts to ask your adviser, a Checks tab that flags problems, and a printable computation page with every formula.
• Backup and restore with Export and Import JSON, CSV export and import of the adjustments, a clear-everything button and a worked example in the README.

Who it is for Owners, bookkeepers and accountants of UAE small and medium businesses who want a transparent estimate and a working paper to discuss with an adviser.

What it is NOT It is not tax or legal advice, not an FTA-approved system and not a return. It does not know any current rate, threshold, relief condition, loss rule or due date, and it models no instalments, group or free zone regimes, transfer pricing, foreign tax credits, interest limits or filing. E-invoicing is not covered. Adjustment types are things worth asking about, not statements of what is deductible.

How it differs from the Corporate Tax Readiness Workbook: that product is an Excel organiser that calculates no tax. This is an offline calculator that does the arithmetic once you enter the rules.
