The tax code requires extensive documentation to establish tax liabilities except for three “safe harbor” provisions and standard deductions which enable taxpayers to reduce their tax obligations without needing to maintain a complete physical documentation system of their expenses. The government provides citizens with approved methods which enable them to deduct their necessary expenses for daily life and job performance.
The Standard Deduction

The Standard Deduction serves as your most effective financial resource. The government grants taxpayers the option to deduct a predetermined sum from their income without needing to record all their expenditures. People will discover that this amount exceeds their total individual receipts.
Educator Expenses

The classroom supply deduction for K-12 teachers and aides allows them to deduct up to $300 of their personal expenses. Educators can deduct this amount on their tax returns because they meet the requirement for qualified education professionals without needing to show receipts for their classroom materials.
Health Savings Account (HSA) Contributions

HSA contributions operate like IRA contributions because they lower your taxable income when you make your deposit. The bank transactions serve as proof because they exist in the digital system, which allows you to deduct expenses without needing receipts for your tax preparation.
Small Cash Charitable Donations

The government permits taxpayers to deduct small cash donations to registered charities without requiring a formal donation letter from the charity, though proper documentation through bank records remains the safest option.
Moving Expenses for Military Members

Active-duty military members who have permanent change of station orders still retain their ability to deduct moving expenses. Members can use standard mileage rates to determine their moving expenses without needing to keep gas station receipts.
State and Local Sales Tax (Standard)

You can select between deducting your state income tax or your state sales tax. IRS Optional State Sales Tax Tables provide you with a deduction option for your state, which does not charge income tax. The deduction offers you a standard deduction that is dependent on your income and family size, which allows you to avoid keeping all your grocery receipts.
The Home Office Simplified Option

The simplified home office measurement system enables remote workers to bypass the complex process of calculating their electricity and internet costs. Home Office users can use the Simplified Option to receive a deduction of $5 for each square foot of their home office space, up to a maximum of 300 square feet. The system operates as a fixed deduction method which does not require you to maintain utility bill documentation.
Standard Mileage Rate

You do not need to maintain vehicle maintenance documentation if you drive your car for business or medical purposes. You can document your travel distance by keeping a mileage log, which allows you to calculate your deduction using the government Standard Mileage Rate.
Jury Duty Pay Surrendered to Employer

The deduction permits you to subtract your jury pay from your income when your employer requires you to deliver your jury pay to the company, but they will continue paying your full salary during your jury duty period. The system ensures that you will not face taxes on funds which you did not actually receive.
