Esther can help with:

Rental Income

Rental income is taxed at standard income tax rates, but you can also deduct the costs of buying and improving a rental property.
Charitable giving

Donations made to qualified charities can be deducted to reduce taxable income.
ITIN

An individual tax identification number (ITIN) helps people file taxes without a Social Security number.
Retirement

Retirement income, pensions, and annuities can change the way you file your taxes.
Estates and Trusts

The estate tax involves the right to transfer property at one’s death. A trust allows a third party to hold assets on behalf of a beneficiary or beneficiaries, with various tax rules for income.
Audits or IRS/state notices

This includes tax audits and notices from the IRS that say there’s an unpaid balance or issue with your return.
Small Business Advanced Certified

Proprietorships, C corps, and S corps all file yearly taxes, but the forms used to file depend on the way the business is set up.
Spanish

File taxes in Spanish. Use a bilingual tax prep checklist to get your docs in order.
