20% Income Deduction 

Business taxpayers who are engaged in the following business types: self-employment, partnerships, S Corps, LLCs – may deduct 20% of their taxable income (phase-outs and income thresholds may reduce the deduction). If qualified, this deduction is reflected on Line #10, Form 1040, even for those who own and rent Commercial Buildings or Residential Rental Property. This provision does not apply to high-income taxpayers.

Maximum Home Mortgage Interest Deduction: Mortgage interest deductions are limited to the first $750,000 of the mortgage (Mortgages created after Dec. 15, 2017). Please refer to Publication 936 (2019), Home Mortgage Interest Deduction from the IRS.

  • California allows deductions for home mortgage interest on mortgages up to $1 million, plus up to $100,000 in equity debt.

Charitable Contributions: Up to 60% of AGI is deductible for 2025 (California 50% of AGI). For non-itemizers (taxpayers who take the standard deduction), in 2025, up to $1,000 is deductible for single filers, and up to $2,000 is deductible for those filing married filing jointly.

7) Holding Period for acquiring a principal residence under Section 1031 exchange – A house exchanged using Section 1031 must be held for a minimum of five years from the date the exchange was completed to exclude any capital gains taxes. One important thing to keep in mind is that, in order to exclude up to $500,000 of gain, the home must be titled in at least one spouse’s name, and the tax return must be filed as married filing jointly.

8) Most taxpayers no longer have the option to carry back the net operating loss (NOL). For most taxpayers, NOLs arising in tax years after 2020 can only be carried forward.

9) Precautions to take with 1040X filings: When amending several years, do not put multiple 1040x filings into one envelope. We recommend our clients to mail in each amendment separately. Submit an amendment (1040X) only after the original tax return (1040) is fully accepted by the IRS. If amendments are received by the IRS prior to the original return, this may cause severe delays and complications. Please do not send related supporting materials with the amendments.

10) Social Security Benefit Rule: A single credit is given for every quarter you have earned income of $1,810 or more as of 2025. 40 credits (10 years) is required to start receiving benefits. The SSA calculates the benefits based on your highest 35 years of earnings.

11) Meals and Entertainment Expenses are for 2025:

 
Type of Expense Deduction

Unlicensed cannabis businesses may deduct cost of goods sold, but may not deduct other business expenses, such as rent and wages.

This summary of credit card transactions will be reported directly to the IRS from the credit card processor. If revenue is calculated correctly (cash sales + credit card sales), reported revenue should almost always exceed the credit card sales. For the 2025 tax year, the 1099-K reporting threshold for third party organizations returns to over $20,000 and more than 200 transactions.

35) Trump Accounts for Newborns

This is a benefit where President Donald Trump will deposit $1,000 into accounts for U.S. children born after December 31, 2024, and before January 1, 2029. Parents can then add $5,000 into the account. The following is a comparison between Section 529 Plans and Trump Accounts (Investment Accounts for Minors):

1) Prime Purpose: A 529 Plan is designed to save for children’s education costs, such as college. A Trump Account, on the other hand, is meant to provide for children’s long-term retirement savings. When the child turns 18, the account will convert into a Traditional IRA.

2) Contribution Limits: The 529 Plan allows for a lifetime contribution of up to $100,000. A Trump Account allows for an annual contribution of up to $5,000 over a 4-year period.

3) Tax Treatment: With a 529 Plan, there are no taxes when the funds are withdrawn for education expenses. With a Trump Account, taxes will be due when the money is withdrawn after the child turns 18.

 4) Withdrawals: With a 529 Plan, withdrawals of up to $20,000 per year are allowed. With a Trump Account, after the child turns 18, they can withdraw funds from the Traditional IRA for any purpose.

5) Ownership: The 529 Plan is owned by the parent or guardian. In the Trump Account, the account becomes the child’s property once they turn 18.

 6) Government Seed Money: The 529 Plan does not receive any seed money from the government. However, the Trump Account receives $1,000 in seed money from the government.

7) Financial Aid Impact: The 529 Plan does not affect eligibility for financial aid. On the other hand, the Trump Account will be considered when calculating financial aid, which may reduce the amount of financial aid the child can receive.
