Quick Answer
Yes, you can deduct state sales tax instead of state income tax, but not both. This benefits residents of states with no income tax (like Texas, Florida) or those who made large taxable purchases. The average sales tax deduction ranges from $3,000-$8,000, while state income tax deductions average $5,000-$15,000 for middle-income earners.

Taxpayers who need to understand the basic choice between state income tax and sales tax deductions
The either/or choice: Income tax vs. sales tax
On Schedule A, Line 5, you must choose to deduct EITHER:
You cannot deduct both in the same year. This choice is subject to the $10,000 SALT cap regardless of which option you select.
Two methods to calculate sales tax deduction
Method 1: Actual sales tax paid
Keep receipts for all purchases and add up the sales tax paid throughout the year. This is tedious but can yield higher deductions if you made large purchases.
Method 2: IRS Sales Tax Tables
Use the IRS optional sales tax tables based on your income and family size, plus add sales tax on major purchases over $1,000.
Example: Comparing both options for different scenarios
Scenario 1: Texas resident (no state income tax)
Scenario 2: California resident with large purchase
Scenario 3: New York resident, normal year

What you should do

Taxpayers who moved between states during the tax year and need to understand how to handle both state income taxes and sales taxes
Multi-state moves complicate the income vs. sales tax choice
When you move between states during the tax year, you may owe income taxes to multiple states, which affects your federal deduction strategy.
Example: Move from California to Texas
In this case, the sales tax deduction ($4,300) exceeds the state income tax paid ($4,000), making sales tax the better choice.
Part-year resident considerations
Income allocation: Some states tax only income earned while a resident, while others tax all income for part-year residents. This affects your total state income tax paid and thus your federal deduction.
Sales tax timing: If you moved to a high-sales-tax state and made major purchases after the move, the sales tax deduction might be surprisingly competitive.
Record-keeping for moves: Maintain separate records for:
Strategic timing around moves
If you know you're moving from a high-income-tax state to a no-income-tax state, consider:
Key takeaway: Multi-state moves often make sales tax deduction more competitive since total state income tax paid may be lower than in a full-year residency scenario.
Key Takeaway: Moving from high-income-tax to no-income-tax states during the year often makes sales tax deduction more beneficial than state income tax deduction.

Taxpayers who earn income in multiple states and may pay income taxes to several states
Multi-state income creates complex deduction scenarios
If you earn income in multiple states, you may pay income taxes to several states while living in one primary state. This can create opportunities for higher state income tax deductions.
Example: Consultant with multi-state income
The combined state income taxes ($9,500) clearly exceed the sales tax option ($4,200).
Credits vs. deductions in multi-state situations
Important distinction: You may receive credits on your resident state return for taxes paid to other states, but you can still deduct the total amount paid to ALL states on your federal return.
Federal deduction: Total of all state income taxes paid
State credit: Credit for taxes paid to other states (doesn't affect federal deduction)
Non-resident state returns and deduction planning
Some strategies for multi-state earners:
Sales tax considerations for frequent travelers
If you travel frequently for work and make purchases in different states:
Key takeaway: Multi-state income typically increases total state income tax paid, making the income tax deduction more valuable than sales tax deduction, even with the SALT cap.
Key Takeaway: Earning income in multiple states usually results in higher total state income tax payments, making state income tax deduction more beneficial than sales tax deduction.
