The 2027 Tax Plan package is now before the House of Representatives. It was submitted on 15 September 2026, and Parliament can still change the measures. The proposals remove some rules but add transition dates, eligibility checks and reporting work that can affect business plans.
Why this matters
Small firms are making decisions before every tax detail is final. Budgets, payroll settings, vehicle contracts and staff reward plans need dates and figures. The proposed youngtimer thresholds are 17 years in 2027 and 20 years in 2028. Proposed employee-option rules require qualification, payroll and share records. This can add work and alter cash needs. Keep current law, proposed law and planning assumptions separate.
Example
A self-employed founder qualifies for the starter deduction. The proposal cuts it from €2,123 to €10 in 2027 and removes it from 1 January 2028. A 2027 forecast using the current deduction may understate taxable income. That can affect the provisional assessment, household cash and income-dependent arrangements. The founder needs one file showing the current rule, the proposal and the next forecast review date.
XTROVERSO tips
- Label every tax assumption. Mark each budget figure as current law, proposed law or an internal scenario. Use the same labels in cash forecasts and payroll files.
- Find decisions with early deadlines. Check vehicle contracts, staff rewards, provisional assessments and owner drawings. Record the date each decision must be made.
- Connect the supporting records. Link contracts, first-registration dates, option agreements, payroll records, valuations and employee details to the relevant tax year.
- Test the cash effect. Run a base case and a proposal case. Check tax payments, payroll, household drawings and the cash buffer.
- Set an owner and review date. Give one person responsibility for following Parliament. Update the planning file at fixed review points, rather than after every headline.
