What Texas Form 01-142 Is For
Texas Form 01-142 is needed to report and pay the Heavy-Duty Diesel Equipment Surcharge that is part of the Texas Emissions Reduction Plan. The Texas Legislature established the surcharge to help fund the Texas Comptroller's efforts to reduce emissions.
The Texas Emission Reduction Plan Fund gets the money from this surcharge. The Texas Commission on Environmental Quality then uses that money for its own projects. These programs adhere to the Transportation Code and the Health and Safety Code to ensure compliance with air quality regulations.
The surcharge applies to the sale, lease, or rental of qualifying off-road diesel equipment in Texas powered by a 50 HP diesel engine or greater. The Heavy Duty Equipment Tax applies only when the transaction is otherwise subject to Texas sales tax.
When You’d Use Texas Form 01-142
Texas Form 01-142 must be filed by businesses that sell, lease, or rent taxable off-road diesel equipment subject to the TERP tax. Buyers must also file if the seller did not collect the surcharge at the time of purchase.
The form is also used to file amended returns or submit a refund claim when errors are discovered after the return has been filed. Common corrections include misapplied tax rates, improper exemption treatment, or refunds issued to customers in error.
The amount of activity in the surcharge liability account over the course of the fiscal biennium will determine how frequently the account is filed. State regulations require larger companies to file reports monthly, while smaller businesses may only be required to file quarterly.
Key Rules or Details for 2022
The surcharge applies only when the underlying transaction is subject to tax. Equipment that qualifies as tax-exempt is also exempt from the surcharge, including agricultural use equipment, agricultural products, and qualifying timber operation machinery.
The 50 HP diesel engine surcharge rate for 2022 is 1.5 percent of the taxable amount. The applicable tax rate is determined by the contract execution date, not the payment date, which is critical for long-term lease agreements.
In most cases, there is a four-year statute of limitations for assessments and refund claims. If a contract is signed with the Texas Comptroller during an audit or review, this timeframe may be prolonged.
Step-by-Step (High Level)
Step 1: Prepare transaction records
Examine service ticket records, sales-by-part-number reports, and invoice format documentation for all eligible transactions to ensure accuracy. Verify that the transactions are not tax-exempt and that the Texas nexus is applicable.
Step 2: Calculate the surcharge base
Total taxable transactions and confirm the surcharge base reflects taxable receipts only. Do not include sales tax in the surcharge base.
Step 3: Compute the surcharge and valid credits
To determine the surcharge, multiply the taxable receipts by the applicable surcharge rate. Only use credits when a documented refund claim has been made and recorded in the GL or liability account.
Step 4: Complete and file Texas Form 01-142
Fill in the header information, the total amount of taxes owed, the surcharge amounts, and any changes. Use the proper method to file: if electronic thresholds apply, use TEXNET; if not, use Webfile or an approved paper option.
Step 5: Submit payment and retain support
Pay by the due date set by law and keep the filing confirmation. Keep master file documentation, exemption certificates, serialized records, and supporting calculations for audits and reconciliations.
Common Mistakes and How to Avoid Them
- Charging surcharge on exempt agricultural/timber equipment: Verify exemption documentation before billing and retain supporting documentation so exempt transactions are not overcollected or questioned in an audit.
- Skipping the 50HP diesel threshold check: Review manufacturer specifications to confirm the equipment meets the 50HP diesel engine requirement before applying the Heavy Duty Equipment Tax.
- Misclassifying lease renewals as original contracts: Treat each renewal or extension based on its own execution date and apply the tax rate tied to that renewal date.
- Refund customers without amending the return: File the amended return or refund claim with supporting documentation to ensure credits are correctly reported and not denied.
- Including standalone replacement parts in surcharge totals: Exclude replacement parts sold separately unless they are bundled with qualifying equipment as part of the taxable package.
What Happens After You File
The Texas Comptroller processes the return and puts the payment into the right liability account after it is filed. People who file electronically receive confirmation right away, but those who file by mail must wait for the postmark date to ensure they are on time.
Provide additional paperwork, such as invoices, proof of payment, and exemption certificates, when requesting a refund. A filer has the option of receiving their authorized refund via direct deposit or check.
Accounts may be chosen for an audit based on refund activity or reporting trends. Invoice records, serialized records, and maintenance documentation for master files are usually examined during audits.
