Comprehensive Federal & Multi-State Resident Return (Form 1040)
Under Internal Revenue Code § 1 and § 7701(b), US citizens, lawful permanent residents (Green Card holders), and resident aliens who meet the Substantial Presence Test are subject to US federal taxation on their worldwide earned income. Preparing a complete and compliant Form 1040 requires accurately consolidating W-2 wage earnings, multiple 1099 statements, equity compensation (RSUs, ESPP, stock options), capital gain transactions on Schedule D, and state income tax allocations across jurisdictions.
Our licensed CPAs perform line-by-line reconciliation of your tax data. We evaluate the optimal threshold between the standard deduction and itemized deductions (Schedule A), claim statutory credits such as the Child Tax Credit and Foreign Tax Credit (Form 1116), and ensure proper basis reporting on stock sales to prevent costly IRS CP2000 automated penalty assessments.

Who is this service designed for?
Statutory filing categories and taxpayer profiles tailored for this specialized service.
US Citizens & Lawful Permanent Residents (Green Card holders) with worldwide earned wages.
H-1B & L-1 visa holders who satisfy the 183-day Substantial Presence Test (SPT).
W-2 tech professionals with RSU equity grants, ESPP, and capital gains/losses.
Families claiming Child Tax Credit ($2,000/child) and dependent care benefits.
Key Statutory Provisions & Tax Deductions We Maximize
Every tax return is optimized under current Internal Revenue Code regulations to secure every legally allowable credit and deduction.
Standard vs. Itemized Deductions (Schedule A)
We benchmark your statutory standard deduction against itemized medical expenses, State and Local Taxes (SALT capped at $10,000), qualified mortgage interest on acquisition debt up to $750,000, and charitable contributions to secure maximum tax savings.
Equity Compensation (RSU, ESPP & Stock Options)
When tech employers vest RSUs or sell shares via ESPP, Box 1 of Form 1099-B often omits the cost basis already included in W-2 wages. We adjust the cost basis on Form 8949 using Code B to prevent double taxation on your equity.
Foreign Tax Credit (Form 1116) & DTAA Relief
For filers with foreign source income such as Indian NRE/NRO interest, overseas rental profits, or dividend earnings, we claim the Foreign Tax Credit (FTC) to offset US liability dollar-for-dollar against taxes paid in India.
Multi-State Nexus & Resident Apportionment
If you relocated between states or worked remotely across state lines, we prepare accurate multi-state returns (e.g., CA 540-NR, NY IT-203, NC D-400), properly apportioning wage income and claiming resident credits to eliminate dual state taxes.
Child & Family Dependent Tax Credits
We secure up to $2,000 per qualifying child under age 17, determine refundable Additional Child Tax Credit eligibility, and capture up to $3,000 in qualifying child and dependent care expenses for working parents.
Retirement & Pre-Tax Optimization
Maximize above-the-line adjustments to gross income including Traditional IRA contributions, Health Savings Account (HSA) deductions, and student loan interest deductions.
