Common questions
Is NetPayGuide as accurate as SmartAsset for paycheck calculations?▾
For 2026 take-home math, yes. Both apply the same IRS Publication 15-T withholding logic, the 2026 Social Security wage base of $184,500, and the same Medicare rates. State brackets are sourced directly from each state revenue department. Differences in final numbers between the two calculators are usually rounding or how pre-tax deductions are categorized — not accuracy.
Does SmartAsset share my data with financial advisors?▾
SmartAsset operates an advisor-matching service called SmartAdvisor that connects users with fiduciary advisors who pay SmartAsset for leads. If you complete the advisor-match flow, your contact information is shared. The paycheck calculator itself does not require this, but the funnel is prominently placed on the page.
Can I save and share a paycheck scenario in SmartAsset?▾
SmartAsset does not encode calculator state in the URL. To share a scenario you would need to screenshot the result or describe the inputs separately. NetPayGuide encodes every input in the URL automatically, so a single link reproduces the exact scenario.
Why does the SmartAsset result sometimes differ from my actual paycheck?▾
Both NetPayGuide and SmartAsset produce withholding estimates based on the standard deduction and zero W-4 adjustments unless you specify otherwise. Real paychecks reflect W-4 step-2 multiple-job adjustments, employer-specific benefit elections, and post-tax deductions like garnishments. Use the actual figures from your most recent pay stub for the closest match.
Which calculator is faster for comparing offers in different states?▾
NetPayGuide is faster because the URL encodes the scenario — you can change the state dropdown and the resulting URL is shareable. SmartAsset requires re-entering most inputs when navigating between state pages.
