Starting in 2026, households and individual businesses will have to switch from paying fixed taxes to tax declaration, meaning all revenue and expenses must have legal invoices and documents. This regulation leaves many household businesses confused as they need to change habits, adopt technology, and manage invoices and documents according to new standards.

So, what should household businesses and taxpayers prepare to ensure the declaration process is quick and smooth? Let’s explore with Meksmart in this article!

1. Transitioning to Tax Declaration: What Challenges Do Household Businesses Face?

Switching to tax declaration certainly comes with many challenges. The biggest difficulty is changing traditional work habits. Many household businesses still record transactions informally, without clear tracking of revenue and expenses. When moving to declaration, they must get used to daily record-keeping, storing invoices, tracking eligible expenses, and issuing electronic invoices for each transaction.

Technology barriers remain a major obstacle for many household businesses. Tasks such as preparing tax returns, using digital signatures, or troubleshooting system errors often cause confusion, especially for those unfamiliar with software. Additionally, fear of mistakes and penalties for late or incorrect declarations makes them hesitant to fulfill tax obligations.

Another common issue is the lack of valid invoices and documents. Many customers are used to buying without requesting invoices or receiving improperly formatted invoices, making it difficult for businesses to justify expenses. Without sufficient documentation, those expenses are not recognized, resulting in higher tax liabilities than expected.

Challenges Household Businesses Face During Tax Transformation

2. Steps to Help Household Businesses Declare Taxes Quickly, Accurately, and Completely

To adapt to the new regulations, household businesses need to understand the laws and prepare thoroughly. The transition is not too difficult, but it requires a proper, complete, and controlled process.

Businesses must re-register their tax payment method, switching from fixed tax to declaration based on actual revenue. This is the first and most important step for the Tax Authority to update information and guide taxpayers through the new process.

In addition, revenue and expense tracking must be continuous and systematic. This can be done using notebooks, Excel, or, most conveniently, sales management software, which allows real-time revenue monitoring and complete data storage for tax declaration.

Finally, to minimize errors, taxpayers should use tax declaration support software. These tools automate most tasks, consolidate revenue and expenses, reconcile data, and generate reports with just a few simple steps. Not only do they reduce mistakes, but they also significantly shorten declaration time—especially useful for those unfamiliar with technology.
