The German government has decided to adjust the tax interest rate in 2021. The background to this is the low level of interest rates that has persisted for years. This is because the previous interest rates for back taxes and tax refunds were significantly higher than the current market interest rates. This resulted in a disproportionately high financial burden for taxpayers.
In the course of the adjustment, the interest rates for tax arrears and tax refunds are to be reduced to the level of the market interest rate. The changed interest rates are to be applied from 1. to come into force on July 2021. For back taxes, the interest rate is then 0.5 percent per month, for tax refunds 0.5 percent per year.
The adjustment of tax interest to the low interest rate level has both advantages and disadvantages for taxpayers. On the one hand, back tax payments can now be settled at lower interest rates, which means a noticeable financial relief. On the other hand, an interest rate of only 0.5 percent per year will be paid on refunds in the future, which is far below the previous interest rates.
Background information
The adjustment of tax interest rates to the low interest rate level has repeatedly caused discussion in recent years. This refers to the interest charged by the tax office on tax arrears if they are not paid on time.
The level of tax interest is based on the respective market interest rate and is intended to ensure that taxpayers do not derive any financial advantage from paying their taxes later. However, in times of low interest rates, the amount of tax interest can also become problematic. This is because taxpayers will then have to pay significantly higher interest than they themselves receive on their credit balances.
Discussions on the adjustment of tax interest to the low interest rate level have repeatedly led to political debates in recent years. While some experts argue for a reduction in tax interest rates, others argue for maintaining the current level. Ultimately, however, it is up to politicians to decide on the adjustment of tax interest rates.
- Tax interest rates to be based on the market interest rate
- High tax interest rates can be problematic
- Political debates on the adjustment of tax interest rates

One way to reduce the burden of high tax interest is to pay your taxes on time. Those who file their tax returns on time and pay the additional payment within the set deadline do not have to pay any or only a small amount of tax interest. Installment payments may also be an option for taxpayers to reduce the burden of high tax interest rates.
However, taxpayers must also keep in mind that the amount of tax interest is an important source of revenue for the government. A reduction in tax interest rates can therefore also lead to revenue shortfalls that have to be offset elsewhere.
- Pay taxes on time
- Payment in installments as an option
- Reduction of tax interest rates may lead to revenue shortfall
Ultimately, taxpayers will need to weigh which option is best for them when adjusting tax rates to the low interest rate environment. In this regard, early payment of taxes can not only save tax interest, but also help to maintain a good relationship with the tax office.
Impact on taxpayers: adjustment of tax interest rates to the low interest rate level
The adjustment of tax interest rates to the low interest rate level has an impact on all taxpayers in Germany. Since interest rates on savings and investments have been very low for several years, the reference rate for calculating tax interest is also decreasing. This will result in lower back taxes and advance tax payments for many taxpayers.
However, this adjustment does not apply to all types of taxes. The tax interest for late tax payments and tax arrears in the context of a tax audit remains unchanged at a high level. Here, taxpayers still face high interest payments if they fail to pay their taxes on time or have made mistakes on their tax returns.
Another effect of adjusting tax interest rates to low interest rates is that the ratio of back taxes to advance taxes changes. Since back taxes are lower, taxpayers may have to adjust their advance tax payments downward to avoid paying too much tax up front.
- CONCLUSIONS:
- Adjusting tax rates to the low interest rate environment has a positive impact on many taxpayers, as back taxes are lower. However, the risk of high interest payments remains for late tax payments and back taxes due to an audit. It is therefore advisable to make tax payments on time and carefully review tax returns to avoid errors.
Criticism and controversy regarding the adjustment of the tax interest rate to the low interest rate level
In the financial world, there has been a debate for years about whether the adjustment of tax interest to the low interest rate level is appropriate and fair. Some economists argue that this move is necessary to promote economic growth. However, there are also critics who claim that the adjustment will lead to an uneven distribution of the tax burden.
Proponents of the adjustment argue that low interest rates can incentivize investment and boost the economy. The adjustment of tax rates is also expected to increase the acceptance of bonds and equities, which in turn may lead to more growth. On the other hand, critics warn that such an adjustment will lead to a burden on savers and retirees who rely on interest income.
- This adjustment could also have a negative impact on life insurance returns.
- There is also the question of whether it is fair that taxpayers with debts benefit from the adjustment of tax interest rates, while those with savings are disadvantaged by it.
- Another controversy is that the distortion of investment decisions among companies may lead them to make riskier decisions in order to achieve higher returns.
Overall, there are many arguments for and against adjusting tax interest rates to the low interest rate environment. What is certain is that this adjustment will have an impact on all areas of the economy and should therefore be carefully considered.
Analysis of the adjustment of tax interest rates to the low level of interest rates
Since 2012, the base interest rate for calculating advance tax payments and back taxes in Germany has been adjusted to the very low interest rate level. As a result, tax interest rates have also been reduced to a very low level. This has led to discussions as to whether the adjustment was appropriate, as it has given companies and individuals a financial advantage.
After a detailed analysis, we can say that the adjustment of tax interest rates to the low level of interest rates was justified. At a time when the European Central Bank has attempted to stimulate the economy by lowering interest rates to historically low levels, it would not have made sense for tax interest rates to remain at high levels.
Considering that the reduction in tax rates did not hurt anyone and the situation in the economy was difficult, the adjustment was a necessary measure. However, it remains to be seen whether tax interest rates will be raised again to a higher level once the economy recovers.
- Conclusion: the adjustment of tax interest rates to the low level of interest rates was an appropriate measure, justified in the context of the economic situation.
- Outlook: It remains to be seen whether tax rates will be raised again to higher levels when the economy recovers.
Tips for taxpayers to adjust tax interest rates to reflect low interest rates
The current low interest rate environment may impact taxpayers who are owed back taxes or are awaiting refunds. In this context, the following recommendations for action should be taken into account:
- Early filing of tax returns: The earlier tax returns are filed, the faster refunds can be processed and paid out. This can help prevent assets from losing value due to low interest rates.
- Tax prepayments: Taxpayers should review their prepayments and have them adjusted if necessary. If they overpay, they may be able to avoid losing interest when interest rates are low.
- Plan payments: Taxpayers should plan their payments so that they are only made when they are due. This allows them to minimize the impact of low interest rates on their payments.
It is important for taxpayers to consider their individual situation and obligations, and if necessary, speak with a tax advisor or financial services provider to find the best options for adjusting their tax rates to the low interest rate environment.
