Key Facts Circa US Taxation

Imposta federale a 7 scaglioni
10% / 12% / 22% / 24% / 32% / 35% / 37% in 2025. Bracket thresholds depend on filing status — MFJ brackets are roughly twice the Single brackets up through 32%, then converge above $626k.
Detrazione standard di >5.000
Single filers deduct $15,000 in 2025. MFJ gets $30,000. Capofamiglia $22,500. Inflation-adjusted yearly. Most taxpayers take the standard rather than itemize after the 2017 SALT cap.

Social Security 6.2% on wages up to $176,100 (2025) plus Medicare 1.45% on all wages. Employer matches. Self-employed pay both halves (15.3% SE tax) but can deduct half.
21 % di imposta sulle società
Federal corporate income tax has been flat 21% since the 2017 Tax Cuts and Jobs Act. Stato corporate rates add 0–11.5%. Pass-through entities (S-corps, LLCs) flow income to owners' personal returns instead.
