Construction

Local context: what changes in United States

Straight to the numbers — here is how Construction behaves under US rules, units and pricing conventions.

Key local facts

• Money & format: Amounts are US dollars written as $1,234.56, with a period as the decimal mark. Sales tax is added at checkout, so advertised prices are pre-tax.
• Tax structure: Federal income tax runs in brackets from 10% to 37%, on top of state income tax that ranges from 0% (TX, FL, WA) to over 13% (CA).
• Payroll: FICA takes 7.65% from the employee (6.2% Social Security + 1.45% Medicare) and the employer matches it; Social Security stops at the annual wage base.
• Units: Imperial by default: miles, pounds, °F, US gallons and feet/inches. A US gallon is 3.785 L, not the 4.546 L imperial gallon.
• Power & standards: Households run on 120 V / 60 Hz with NEMA Type A/B plugs, and wiring sizes follow AWG under the NEC, not mm².

Local examples

• Example — Texas: A homeowner in Austin runs Construction with local rates, then checks the output against a contractor quote before signing.
• Example — New York: A freelancer in NYC uses Construction to separate federal, state and city obligations before setting aside quarterly estimates.
