Insufficient input credits are the industry's chronic tax problem: labour, sand and gravel and small purchases often come without a special invoice, so the effective rate far exceeds the nominal 9%. Whether to use the general or simplified method therefore depends on how many credits you can collect. This tool does arithmetic only and is not tax advice — filing follows the local tax authority.

Formula
| Net amount | gross ÷ (1 + rate) |
| Output tax | gross − net |
| VAT payable | output − input credit |
| Surcharges | payable × surcharge rate |
| Total tax | payable + surcharges |
| Effective rate | total tax ÷ net |
One million gross at 9% with 50,000 of credits: 917431 net, 82569 output tax, 32569 payable, 3908 surcharges — 36477 in total, an effective rate of 3.98%.
How to work it out
- Separate tax-inclusive from tax-exclusive amounts first. Contract values and invoices are usually inclusive, while cost analysis needs exclusive figures — a 9% gap under the general method.
- Exclusive amount N = inclusive ÷ (1 + rate). One million inclusive at 9% gives 1,000,000 ÷ 1.09 = 917,400.
- Output VAT O = inclusive − N = 82,600. That is what is declared on the invoice.
- VAT payable V = output tax − deductible input tax. Input tax comes from properly issued special invoices on materials, subcontracts and plant hire. On one million inclusive with 50,000 input, the payable is 32,600.
- Surcharges S = V × surcharge rate. Urban maintenance tax 7% in city districts, education surcharge 3%, local education surcharge 2% — 12% in total.
- Effective burden = (VAT payable + surcharges) ÷ exclusive revenue. For construction, 2-4% is normal; markedly lower invites scrutiny.
Where it goes wrong
- Multiplying the inclusive amount by the rate. One million × 9% = 90,000 is wrong; the correct figure is 1,000,000 − 1,000,000 ÷ 1.09 = 82,600, an overstatement of 7,400.
- Forgetting input tax. Computing output tax alone overstates the liability by more than double. Materials, subcontracts, plant hire and equipment purchases all generate deductible input.
- Mixing the simplified and general methods. Labour-only packages, client-supplied materials and legacy projects may elect 3% simplified treatment, but then input tax is not deductible. Compare the two in total rather than picking the lower headline rate.
- Applying 7% urban maintenance tax everywhere. It is 7% in city districts, 5% in counties and towns, and 1% elsewhere. Using the wrong band misstates surcharges by 40%.
Material and cost
Construction services VAT: 9% under the general method, 3% simplified (labour-only, client-supplied materials, projects predating 30 April 2016). Surcharges total 12% of VAT payable on the city-district basis. Corporate income tax at 25%, with relief for small low-profit enterprises, sits outside this tool.
On site
- Certify input invoices promptly. The certification deadline has been abolished, but invoices should still be collected in step with progress, or the current-period liability is inflated and cash is tied up.
- Client-supplied materials are the classic trap: the client takes the input credit and the contractor provides services only, so the tax base excludes those materials. Contracts and invoices must align.
- Cross-county projects require prepayment locally — 2% under the general method, 3% under the simplified — with the return filed at the registered location.
- An anomalous effective rate triggers audit. General-method construction projects normally sit at 2-3.5%; below 1.5% needs a clear explanation, such as a large share of simplified-method work.

FAQ
Why is the effective rate 4% when the nominal rate is 9%?
Because VAT taxes value added, not turnover — output tax less input credits is what you pay, and materials, plant and subcontracts all generate credits. The effective rate tracks how many invoices you collect: 80% coverage gives 2-4%, 40% gives over 6%. That is why paperwork is the heart of construction tax management.
What are surcharges based on?
On the VAT actually paid, not on revenue: 7% urban construction tax in city areas, 3% education surcharge and 2% local education surcharge — 12% in total. If a credit balance means no VAT is payable, there are no surcharges either. Small-scale taxpayers get a 50% reduction in many places, so check local policy.
When is the simplified method cheaper?
When credits cover less than about 30% of costs. Simplified charges 3% on the full amount with no credits; general charges 9% but allows them. Setting p as credits over output tax, 3% = 9% × (1 − p) gives p = 67% — so once credits fall below two thirds of output, simplified wins. Labour-only and client-supplied-material jobs usually qualify.
