how it works
Marriage Allowance is a tax relief for married couples or civil partners. If one of you earns less than the personal allowance (£12,570) and the other is a basic-rate taxpayer, you can transfer some of your unused tax-free allowance reducing your joint tax bill.

My experience with Taxbax was very positive, and I would absolutely recommend them to a friend. They secured over £2,000 in tax benefits for me, which was an excellent outcome. I’m already looking forward to working with them again next year on my next claim. I’m glad I chose Taxbax, and I want to highlight Fatim, who was amazing throughout the process. She was extremely helpful, and I’ll be encouraging others to speak with her directly to get their claim resolved.

My experience with Taxbax has been very good, and I would definitely recommend them to others. They secured a total benefit of £7,230 for me, which was a fantastic result. I’m already planning to work with them again next year on my next claim and have recommended the company to my wife and friends. I was especially impressed with Laura, who was very attentive and supportive throughout the whole process. She really made the experience smooth and straightforward for me.
Gareth Smith
My dealings with Taxbax were very straightforward, and I would not hesitate to recommend them to others. My claim came to around £8,000, which was an excellent result and far beyond what I expected. I am definitely looking forward to working with Taxbax again next year for another claim. I dealt with Rhiannon, and everything went so smoothly from start to finish. I was delighted with the care and attention I received and felt very well supported throughout the process.
