State estimated tax: You must make estimated payments if your Rhode Island income tax is expected to be $250 or more above allowable credits, whether or not you must pay federal estimated tax. Same dates as federal (April 15, June 15, September 15, January 15) Form RI-1040ES.
LLC annual charge (minimum tax): Every LLC not taxed as a corporation, including a single-member LLC, pays an annual charge equal to the $400 corporate minimum tax. A $100 addition applies if paid late. Sole proprietors without an LLC do not owe it.
Worker misclassification law (R.I. Gen. Laws § 28-14-19.1): Treating a worker as an independent contractor when they should be an employee violates the state wage law. The Department of Labor and Training investigates complaints using federal FLSA factors and may refer cases for criminal prosecution.
Healthcare Worker Platform Act (2026-H 7030B / S 2107A): Signed into law in 2026. It allows app-based platforms where healthcare workers such as CNAs, LPNs, and RNs pick up shifts at healthcare facilities. The Department of Health will license each platform, and the law adds background checks, worker and patient protections, inspections, and annual reporting.

Federal rules for 2026

Solo 401(k) up to $72,000

A one-person consultancy can contribute a $24,500 employee deferral plus an employer share of about 20% of net self-employment earnings, up to $72,000 in 2026, plus an $8,000 catch-up at 50 or older ($11,250 at ages 60 to 63).

The S-corp trade-off

Electing S-corp status can cut payroll tax, but the salary you pay yourself also sets your Solo 401(k) room. Run both sides before you elect.

Quarterly estimated taxes

No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.

Self-employment tax

On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.

A worked example

A consultant with $150,000 of net profit in 2026
Self-employment tax (sole proprietor)	$21,194
Solo 401(k) maximum	$52,381
SEP IRA maximum	$27,881
Payroll tax saved as an S-corp on a $75,000 salary	$9,719
Solo 401(k) maximum as that S-corp	$43,250
